Understanding Chinese characters for science experiments and lab vocabulary is essential for expat students studying in China, especially if you are attending university, working in research, or simply curious about science. Mastering these characters will help you read lab instructions, communicate with professors, and understand scientific articles in Mandarin. In this post, we will cover essential words, phrases, and sentences used in a laboratory setting.
Basic Lab Vocabulary
When you first enter a lab, some of the most common items and tools you will encounter include test tubes (试管, shìguǎn), microscopes (显微镜, xiǎnwēijìng), beakers (烧杯, shāobēi), and pipettes (移液管, yí yè guǎn). Knowing these words allows you to follow instructions and communicate with lab partners. For example:
这个实验需要用试管 (zhège shíyàn xūyào yòng shìguǎn) – This experiment requires using a test tube.
请把显微镜调高一点 (qǐng bǎ xiǎnwēijìng tiáo gāo yīdiǎn) – Please adjust the microscope to a higher position.
烧杯里有一百毫升水 (shāobēi lǐ yǒu yī bǎi háoshēng shuǐ) – There are 100 milliliters of water in the beaker.
Performing Experiments
In Chinese labs, teachers or lab manuals often use instructions containing imperative verbs. Some common verbs are measure (测量, cèliáng), mix (混合, hùnhé), heat (加热, jiārè), and observe (观察, guānchá). Example sentences include:
请测量溶液的温度 (qǐng cèliáng róngyè de wēndù) – Please measure the temperature of the solution.
把两种化学物质混合在一起 (bǎ liǎng zhǒng huàxué wùzhì hùnhé zài yīqǐ) – Mix the two chemicals together.
加热烧杯中的液体五分钟 (jiārè shāobēi zhōng de yètǐ wǔ fēnzhōng) – Heat the liquid in the beaker for five minutes.
观察显微镜下的细胞 (guānchá xiǎnwēijìng xià de xìbāo) – Observe the cells under the microscope.
Describing Experiments
In science, describing procedures and results is important. Words like reaction (反应, fǎnyìng), solution (溶液, róngyè), sample (样品, yàngpǐn), and experiment (实验, shíyàn) are frequently used. Sentences you may encounter include:
这个反应产生了气泡 (zhège fǎnyìng chǎnshēngle qìpào) – This reaction produced bubbles.
溶液需要静置十分钟 (róngyè xūyào jìngzhì shí fēnzhōng) – The solution needs to stand for ten minutes.
每个学生都需要准备一个样品 (měi gè xuéshēng dōu xūyào zhǔnbèi yī gè yàngpǐn) – Every student needs to prepare a sample.
这个实验非常复杂 (zhège shíyàn fēicháng fùzá) – This experiment is very complex.
Safety and Instructions in the Lab
Safety is crucial in any lab environment. You will often see signs and instructions using words like wear (戴, dài), gloves (手套, shǒutào), goggles (护目镜, hùmùjìng), and dangerous (危险, wēixiǎn). Example sentences include:
进入实验室前请戴护目镜 (jìnrù shíyànshì qián qǐng dài hùmùjìng) – Please wear goggles before entering the laboratory.
操作化学品时必须戴手套 (cāozuò huàxuépǐn shí bìxū dài shǒutào) – Gloves must be worn when handling chemicals.
请小心，这里很危险 (qǐng xiǎoxīn, zhèlǐ hěn wēixiǎn) – Be careful, it is very dangerous here.
遵守实验室规则非常重要 (zūnshǒu shíyànshì guīzé fēicháng zhòngyào) – Following lab rules is very important.
Recording Observations and Results
When writing reports or taking notes, words like record (记录, jìlù), result (结果, jiéguǒ), graph (图表, túbiǎo), and data (数据, shùjù) are commonly used. Example sentences:
请记录实验的所有步骤 (qǐng jìlù shíyàn de suǒyǒu bùzhòu) – Please record all the steps of the experiment.
实验结果显示温度升高了 (shíyàn jiéguǒ xiǎnshì wēndù shēnggāole) – The experiment results show that the temperature increased.
把数据画成图表 (bǎ shùjù huà chéng túbiǎo) – Plot the data into a graph.
这个记录非常详细 (zhège jìlù fēicháng xiángxì) – This record is very detailed.
Practical Communication in the Lab
Communicating with lab partners and teachers requires phrases like I need help (我需要帮助, wǒ xūyào bāngzhù), Can you explain (你能解释吗, nǐ néng jiěshì ma), and I don’t understand (我不懂, wǒ bù dǒng). Sentences:
我需要帮助来完成这个实验 (wǒ xūyào bāngzhù lái wánchéng zhège shíyàn) – I need help to complete this experiment.
你能解释一下实验步骤吗 (nǐ néng jiěshì yīxià shíyàn bùzhòu ma) – Can you explain the experiment steps?
我不懂这个实验结果 (wǒ bù dǒng zhège shíyàn jiéguǒ) – I don’t understand the results of this experiment.
请指导我如何使用移液管 (qǐng zhǐdǎo wǒ rúhé shǐyòng yí yè guǎn) – Please guide me on how to use the pipette.
