在实验室内记录实验的结果,常用照像法和机械记纹法,其中机械记纹法在实验室内或教学上用得最广,因该法在使用上比照像法简便,但是记纹法也要用很多时间来薰纸、染纸、干燥等麻烦手续。如果实验时间较长,往往中途需要换薰烟纸,尤感不便,虽然可用双鼓,仍感不足。近年来虽有设计用墨水直接在纸上记纹,但是性能有限,适用范围仍然较小,故迄今实验室内和教学上,还是采用薰烟纸记纹法来记录实验的结果。最近我设计成功一种笔尖可装在槓桿、检压
In the laboratory record the results of the experiment, the commonly used photographic method and mechanical Jiwen law, in which the mechanical Jiwen law in the laboratory or teaching the most widely used because the method in the use of photographic than simple, but Ji pattern Law also use a lot of time to smoked paper, dyed paper, dry and other troublesome procedures. If the experiment time is longer, often need to change the cigarette paper halfway, especially inconvenient, although the available double drum, still not enough. In recent years, although the design of ink directly on the paper in mind, but the performance is limited, the scope of application is still small, so far in the laboratory and teaching, or the use of smoked paper Zhiwen method to record the results of the experiment. Recently I designed a tip can be mounted on the lever, check
