德国化学家罗伯特·本生发明本生灯。
首先,取一烧杯的水,在本生灯上微微加热。

他还发明了早期的本生灯装置,几乎所有的实验室都使用它作为最便利的热源。
He also invented the earliest form of the device that was to become the Bunsen burner, which is used almost universally in science laboratories as a convenient source of heat.
在每一次本生灯灯火焰燃烧10秒钟移开后,没有任何一个试片被火焰点燃超过10秒钟。
The specimens may not burn with flaming combustion for more than 10 seconds after either application of the test flame.
本生:德国化学家,是光谱分析领域的先驱,与人合作发现了铯和铷两种元素。1855年发明了本生灯。
German chemist who pioneered in spectrum analysis and codiscovered the elements casium and rubidium. he introduced the bunsen burner in1855.
我告诉他别浪费宝贵的时间和金钱时,他抄起一个培养皿就扔过来,砸中我的鼻梁又弹开,我不得不拿一盏本生灯逼住他。
When I told him to stop wasting valuable time and money, he bounced a petri dish off the bridge of my nose, and I was forced to hold him at bay with the Bunsen burner.
在最近的一次旅行中,我尝试了一下,非常有趣,不过需要手巧一点,很像以前在学校里上的化学课,只是没有实验用的本生灯(Bunsenburner)。
I tried this for a trip recently and it was quite fun to do, if a bit fiddly, much like an old chemistry class at school, minus the Bunsen burner.
