검출하다 en 30 secondes
- To find or detect something specific, often using science or equipment.
- Used in technical and scientific contexts for identification.
- Implies a process of testing or measurement.
- Similar to 'detect' or 'identify' in English.
The Korean verb 검출하다 (geomchulhada) is used to describe the act of finding or identifying the presence of something, typically through a process of detection, examination, or scientific testing. It implies a deliberate effort to discover or ascertain whether a particular substance, signal, element, or even a condition exists. This word is commonly encountered in contexts involving scientific research, medical diagnostics, security, environmental monitoring, and technological applications.
When we use 검출하다, we are often referring to a situation where we are looking for something specific that might be hidden, subtle, or present in small quantities. For example, scientists might use this verb when they are trying to 검출하다 a new virus in a patient's sample, or when engineers are attempting to 검출하다 a fault in a complex system. In environmental science, it's used to 검출하다 pollutants in water or air. The core idea is the successful identification or realization of something's existence after an investigative process.
The term suggests a level of precision and often relies on specialized equipment or methods to achieve the detection. It's not just about casually noticing something; it's about actively finding and confirming its presence. Consider the difference between simply seeing a spider and using a specialized trap to 검출하다 the presence of a particular species of spider in a given area. The former is observation, while the latter is detection using a method.
In everyday language, while less common than in technical fields, it can be used metaphorically. For instance, one might say they are trying to 검출하다 the underlying cause of a problem, implying a search for a hidden root. However, its primary domain remains scientific and technical. The process of 검출하다 often involves comparing observed data against a known standard or looking for specific signatures that indicate the presence of the target entity.
The verb carries a sense of confirmation and verification. It's not just about suspecting something is there; it's about proving it through a systematic process. This is why it's so prevalent in fields where accuracy and evidence are paramount. When a sensor is designed to 검출하다 changes in temperature, it's built to specifically identify and report those fluctuations, not just general environmental shifts. The act of detection is crucial for making informed decisions, whether in medical treatment, safety protocols, or scientific discovery.
의사가 환자의 혈액에서 바이러스를 검출하다.
이 장비는 미세한 금속 조각을 검출하다.
탐지견이 숨겨진 폭발물을 검출하다.
Using 검출하다 correctly involves understanding its grammatical structure and the typical subjects and objects it pairs with. As a verb, it follows the standard Korean sentence structure, often appearing at the end of a clause or sentence. The typical pattern is Subject + Object + 검출하다.
The subject is usually an entity performing the detection, such as a person (doctor, scientist, technician), an instrument, or a system. The object is what is being detected – a substance, a signal, a condition, or an anomaly. For example, a scientist (subject) might 검출하다 a specific gene (object).
Let's look at some common sentence structures:
- Basic Structure
- [Subject]은/는 [Object]을/를 검출하다.
Example 1:
과학자들이 새로운 항체를 검출했습니다.
Here, '과학자들' (scientists) is the subject, and '새로운 항체' (a new antibody) is the object. The verb is conjugated to the past tense '검출했습니다'.
- With Instruments
- [Instrument]은/는 [Object]을/를 검출하다.
Example 2:
이 센서는 유해 가스를 검출할 수 있습니다.
In this case, '이 센서' (this sensor) is the subject, and '유해 가스' (harmful gases) is the object. The phrase '검출할 수 있습니다' means 'can detect'.
- With Specificity
- [Subject]은/는 [Specific Item]의 존재를 검출하다.
Example 3:
연구팀은 토양에서 특정 박테리아의 존재를 검출하는 데 성공했습니다.
Here, '연구팀' (research team) is the subject, and '특정 박테리아의 존재' (the presence of a specific bacteria) is the object. The phrase '검출하는 데 성공했습니다' means 'succeeded in detecting'.
The verb can also be modified by adverbs to indicate the manner or degree of detection, such as '정확하게 검출하다' (to detect accurately) or '쉽게 검출하다' (to detect easily).
You will most frequently encounter the verb 검출하다 in formal and technical settings. It's a staple in discussions related to science, technology, and specialized fields. Here are some common scenarios and contexts where this word is used:
1. Scientific Research and Laboratories: This is arguably the most common domain. Scientists use 검출하다 when discussing experiments, analyses, and discoveries. Whether it's detecting a specific protein in a biological sample, a new element in a chemical reaction, or a signal from a distant star, the verb is essential.
연구 결과, 시료에서 미량의 납이 검출되었습니다.
2. Medical and Health News: When reporting on diseases, diagnostic tests, or public health alerts, 검출하다 is frequently used. News articles about the detection of viruses, bacteria, cancerous cells, or specific biomarkers will employ this term.
새로운 변종 바이러스가 공항에서 검출되었다는 소식입니다.
3. Technology and Engineering: In fields like electronics, telecommunications, and manufacturing, 검출하다 is used to describe the function of sensors, testing equipment, and diagnostic systems. This includes detecting errors, faults, signals, or specific materials.
이 시스템은 비정상적인 활동을 자동으로 검출합니다.
4. Environmental Monitoring: When discussing pollution, climate change, or natural resource management, environmental agencies and researchers use 검출하다 to report on the presence of pollutants, specific gases, or changes in environmental conditions.
대기 중 미세먼지 농도가 기준치 이상으로 검출되었습니다.
5. Security and Forensics: In security contexts, such as at airports or for law enforcement, 검출하다 is used for detecting contraband, explosives, or other dangerous items. Forensic scientists use it to detect evidence at a crime scene.
공항 검색대에서 위험 물질이 검출될 경우 즉시 경보가 울립니다.
6. Industrial and Quality Control: Manufacturers use 검출하다 in quality control processes to identify defects in products or raw materials.
생산 라인에서 불량품을 검출하는 자동화 시스템이 도입되었습니다.
While 검출하다 is a precise term, learners might make mistakes by using it in inappropriate contexts or confusing it with similar-sounding but distinct verbs. Understanding these pitfalls can significantly improve your accuracy.
1. Using it for General Observation: 검출하다 implies a process of active investigation or the use of tools. It's not suitable for simply noticing something obvious. For instance, you wouldn't say you 검출하다 a chair in a room; you would just see it.
- Incorrect Usage
- 나는 방에서 의자를 검출했다. (I detected a chair in the room.)
- Correct Usage
- 나는 방에서 의자를 봤다. (I saw a chair in the room.)
2. Confusing with '발견하다' (balgyeonhada - to discover): While both involve finding something, '발견하다' often implies a more general discovery, sometimes accidental, and can be used for abstract concepts or new findings. 검출하다 is more specific to the act of detection through testing or measurement.
- Incorrect Usage
- 이 기계는 새로운 이론을 검출한다. (This machine detects a new theory.)
- Correct Usage
- 이 기계는 새로운 이론을 발견하는 데 도움을 준다. (This machine helps discover a new theory.)
- 이 장비는 특정 신호를 검출한다. (This equipment detects a specific signal.)
3. Overusing in Casual Conversation: As mentioned, 검출하다 is a formal and technical term. Using it in everyday chats about simple matters can sound unnatural or overly academic.
- Incorrect Usage
- 오늘 아침에 피곤함을 검출했어. (I detected tiredness this morning.)
- Correct Usage
- 오늘 아침에 피곤함을 느꼈어. (I felt tired this morning.)
4. Incorrect Particle Usage: While less common, learners might sometimes misuse the object particle '을/를'. Ensure it correctly follows the noun representing what is being detected.
5. Using for Intent vs. Action: 검출하다 refers to the successful act of detection. Avoid using it when simply intending to search or look for something without confirmation.
While 검출하다 is specific, several other Korean words share overlapping meanings or can be used as alternatives depending on the nuance and context. Understanding these differences helps in choosing the most precise word.
1. 발견하다 (balgyeonhada): To discover, to find.
- 검출하다 vs. 발견하다
- 검출하다 is about detecting something specific through a process, often scientific or technical. '발견하다' is broader; it can mean to discover something new, to find something lost, or to realize something, often with less emphasis on the method of detection.
연구원은 새로운 행성을 발견했다.
이 장비는 특정 파장의 빛을 검출한다.
2. 찾아내다 (chajanaeda): To find out, to locate, to ferret out.
- 검출하다 vs. 찾아내다
- '찾아내다' implies actively searching for and successfully finding something, often something that was hidden or difficult to locate. It can be used in both technical and non-technical contexts, but 검출하다 is more formal and scientific.
경찰은 용의자의 은신처를 찾아냈다.
실험에서 예상치 못한 물질이 검출되었다.
3. 감지하다 (gamjihada): To sense, to detect (often passively or intuitively).
- 검출하다 vs. 감지하다
- '감지하다' often refers to sensing subtle changes or signals, sometimes without explicit tools, or through a more passive reception. It can be used for feelings, atmospheres, or faint signals. 검출하다 implies a more active, often instrument-based, confirmation of presence.
그녀는 주변의 싸늘한 분위기를 감지했다.
이 장치는 초음파를 감지할 수 있습니다.
4. 탐지하다 (tamjihada): To detect, to scout, to reconnoiter.
- 검출하다 vs. 탐지하다
- '탐지하다' is very close to 검출하다, often used in contexts of searching for something hidden or unknown, like enemies, signals, or underground resources. It carries a sense of active searching and locating. 검출하다 might focus more on the confirmation of presence once a method is applied.
군대는 적의 움직임을 탐지하기 위해 정찰기를 보냈다.
금속 탐지기가 동전을 검출했습니다.
In summary, choose 검출하다 when the emphasis is on scientific or technical detection, confirmation through measurement or testing. For broader discovery, use '발견하다'. For active searching and locating, '찾아내다' or '탐지하다' are good options, with '탐지하다' often implying a more systematic search for hidden things. '감지하다' is for sensing or detecting subtle changes, sometimes more passively.
How Formal Is It?
Le savais-tu ?
The Hanja characters 檢 (검) and 出 (출) together imply a process of rigorous inspection leading to the emergence or revelation of a finding. This etymology perfectly captures the essence of scientific or technical detection, where an examination process is crucial to confirm the presence of something.
Guide de prononciation
- Pronouncing '검' (geom) too softly or like 'com'.
- Not aspirating the 'ch' in '출' (chul), making it sound like 'sul'.
- Rushing the final '하-다' (ha-da) or not enunciating the vowels clearly.

Informal/FigurativeFacile à confondre
Both verbs relate to finding something that wasn't previously known or apparent.
<strong>검출하다</strong> emphasizes the process of detection through scientific methods, testing, or equipment, focusing on confirming the existence of something specific. '발견하다' is a more general term for discovering or finding something, which can be accidental, intuitive, or a result of broader exploration, not necessarily tied to a specific detection process.
과학자는 새로운 물질을 <strong>검출</strong>하기 위해 실험을 했다. (The scientist conducted an experiment to detect a new substance.) vs. 그는 우연히 오래된 유물을 <strong>발견했다</strong>. (He accidentally discovered an ancient artifact.)
Both <strong>검출하다</strong> and '탐지하다' are used for finding things, often in technical or search-related contexts.
<strong>검출하다</strong> often implies a more definitive confirmation of presence through measurement or analysis, typically using specific instruments. '탐지하다' can involve a broader search, reconnaissance, or scouting for something hidden or unknown, like enemies or resources. While overlapping, '탐지하다' might carry a stronger sense of active searching or surveying.
이 장비는 미세한 방사능을 <strong>검출</strong>할 수 있다. (This equipment can detect faint radiation.) vs. 군대는 적의 침투를 <strong>탐지</strong>하기 위해 정찰기를 보냈다. (The military sent a reconnaissance plane to detect enemy infiltration.)
Both verbs refer to becoming aware of something's presence.
<strong>검출하다</strong> is typically used for active, often instrumental, detection and confirmation of specific substances, signals, or conditions. '감지하다' refers to sensing or perceiving something, often more subtly, intuitively, or passively, such as sensing an atmosphere, a faint signal, or a slight change. It doesn't always imply a rigorous testing process.
센서가 온도 변화를 <strong>검출</strong>했다. (The sensor detected the temperature change.) vs. 그녀는 분위기의 변화를 <strong>감지했다</strong>. (She sensed the change in atmosphere.)
Detection often leads to identification.
<strong>검출하다</strong> is the act of finding or confirming the presence of something. '식별하다' is the act of recognizing, distinguishing, or identifying what has been detected. Detection is the 'finding', identification is the 'naming' or 'knowing what it is'.
이 기기로 특정 바이러스를 <strong>검출</strong>한 후, 전문가가 그것이 무엇인지 <strong>식별</strong>했다. (After detecting the specific virus with this device, an expert identified what it was.)
Detection often involves measuring specific properties.
<strong>검출하다</strong> is about confirming the existence of something. '측정하다' is about quantifying a characteristic of something, such as its size, amount, temperature, or intensity. You might detect the presence of a gas (검출하다) and then measure its concentration (측정하다).
이 장비는 미세먼지를 <strong>검출</strong>하고, 그 농도를 <strong>측정</strong>합니다. (This equipment detects fine dust and measures its concentration.)

Learners might incorrectly use the active form when the passive is more appropriate, especially in reporting results. For example, saying 'The sensor detected the anomaly' instead of 'The anomaly was detected by the sensor' (which would use <strong>검출되다</strong>).

Mémorise-le
Moyen mnémotechnique
Imagine a detective (검사 - geomsa, meaning inspector/detective) examining a crime scene. He carefully checks (검사) everything, and a hidden clue suddenly comes out (출현 - chulhyeon, meaning appearance/emergence). So, the detective '검' inspects to make clues '출' come out.
Association visuelle
Picture a magnifying glass (representing examination) over a chemical beaker from which a small, glowing particle emerges (representing detection). The magnifying glass for '검' and the emerging particle for '출'.

Try to describe a simple scientific experiment you might have seen on TV, using the word 검출하다 to explain what the equipment was doing.
Origine du mot
The word 검출하다 is a Sino-Korean word, derived from Chinese characters. The first character '검' (geom) comes from 檢 (jiǎn), meaning 'to inspect', 'to examine', or 'to check'. The second character '출' (chul) comes from 出 (chū), meaning 'to come out' or 'to emerge'. Thus, literally, it can be understood as 'to examine and come out', implying an examination process that reveals something.
Sens originel : To examine and reveal the existence of something.
Sino-Korean (derived from Chinese)Contexte culturel
The word itself is neutral. However, the context in which it's used can be sensitive. For example, detecting diseases or dangerous substances can cause anxiety. The successful detection of evidence in forensic contexts is crucial for justice.
In English-speaking cultures, the concept of detection is also highly valued, particularly in scientific, medical, and security fields. Terms like 'detect', 'identify', and 'diagnose' are common. The technological advancements that enable precise detection are often showcased and celebrated.

Questions fréquentes
10 questions검출하다 specifically refers to detecting the presence of something through a process of scientific testing, measurement, or specialized equipment. It's about confirming existence. '발견하다' is a broader term meaning 'to discover' or 'to find', which can be accidental, intuitive, or a result of general exploration without necessarily involving a specific detection method. For example, a scientist might 검출하다 a new compound in a lab, while an explorer might '발견하다' a new island.
You should use 검출되다 (to be detected) when the focus is on the object that has been found, rather than the person or instrument that performed the detection. It's very common in reports and scientific findings. For example, '시료에서 유해 물질이 검출되었습니다.' (Harmful substances were detected in the sample.) Here, the emphasis is on the substances being detected.
Generally, 검출하다 is a formal and technical term. You are unlikely to hear it in casual conversations among friends unless they are discussing scientific, medical, or technological topics. In everyday situations, you would use verbs like '보다' (to see), '느끼다' (to feel), or '찾다' (to look for/find) instead.
Many things can be 검출하다ed, including physical substances (like viruses, pollutants, chemicals, metals), signals (like radio waves, sound waves), conditions (like temperature changes, pressure fluctuations), anomalies (like defects in products, unusual network activity), and even biological markers or genetic mutations.
While its primary use is literal and technical, it can be used metaphorically to describe the act of identifying or uncovering something hidden or abstract, similar to how 'detect' might be used in English. For example, one might say they are trying to 검출하다 the underlying cause of a problem. However, this usage is less common and might sound a bit formal or literary.
Both verbs mean 'to detect'. 검출하다 often implies a more precise confirmation of presence through scientific measurement or analysis, commonly using specific instruments. '탐지하다' can imply a broader search, reconnaissance, or scouting for something hidden or unknown, like enemies or underground resources. While they overlap, '탐지하다' might suggest a more active searching process.
Use 검출하다 for active, often instrumental, detection and confirmation of specific things. Use '감지하다' for sensing or perceiving things more subtly, intuitively, or passively, like sensing an atmosphere or a faint signal. For instance, a sensor 검출하다s a gas, but a person might 감지하다 a change in mood.
Common phrases include '검출되다' (to be detected), '검출할 수 있다' (can detect), '검출되지 않다' (not detected), '검출률' (detection rate), and '검출 한계' (detection limit). You'll also frequently see collocations like '바이러스를 검출하다' (to detect a virus) or '오염 물질을 검출하다' (to detect pollutants).
The Hanja for 검출하다 are 檢出. '검' (geom) comes from 檢 (jiǎn), meaning 'to inspect' or 'examine', and '출' (chul) comes from 出 (chū), meaning 'to come out' or 'emerge'. This etymology highlights the process of examination leading to revelation.
Certainly. For example, '공항 검색대에서 위험 물질이 검출되면 즉시 경보가 울립니다.' (If dangerous substances are detected at the airport security checkpoint, an alarm sounds immediately.) Here, 'detect' refers to the security equipment finding prohibited items.
