由于华氏呼吸计具有微量和进行多组测定的特点,因此至今仍为研究植物呼吸作用、光合作用、酶活性的重要工具。测量反应瓶的体积是一项使用该仪器时最基础的与关系到使用该仪器精确度高低的重要工作。我们采用水银称重法测量反应瓶体积时,曾做了下列改进。一、净化水银水银不干净,不仅易使水银与压力计的管壁以及反应瓶壁之间留有间隙,而且易
Due to the small amount of Fahrenheit respirometer and the determination of multiple groups, it is still an important tool for studying plant respiration, photosynthesis and enzyme activity. Measuring the volume of a reaction flask is one of the most important things that comes to mind when using this instrument and relates to the accuracy of using this instrument. When we measured the volume of the reaction flask using the mercury weighing method, we made the following improvements. First, purifying mercury Mercury is not clean, not only easy to make the mercury and the wall of the pressure gauge and the reaction bottle wall leaving a gap, but also easy
