一、引言有时为了快速地校核电子管的性能,观察有沒有不正常的現象存在,或者要很快的记录电子管特性的数据,利用曲线显示法在示波器上直接观察电子管整个特性是一种最方便的方法,在課堂教学时用作表演更是生动。在1954年3月及1956年1月的物理学报上,曾先后刊登过两篇利用脈冲技朮調亮示波器栅极的方法和綫路。我們将其进行了仔細的究究。在原材料容易置备,以及装置和使用都非常簡便的原則下,我們也进行了一种綫路的設計,裝置和使用的結果,尚称滿意,現特将其介紹如下:
First, the introduction Sometimes in order to quickly check the performance of the tube to observe whether there is any abnormal phenomenon, or to quickly record the characteristics of the tube data, the use of curve display method in the oscilloscope direct observation of the entire tube characteristics is the most convenient Way, it is even more vivid to use for the performance in class teaching. In March 1954 and January 1956, the Journal of Physics, has published two methods and lines using pulse technology to tune the oscilloscope gate. We conducted a careful study of it. We are also satisfied with the design, installation and use of a circuit, which is easy to prepare, easy to set up and use, and is described below.
