一前言近代无线电电子学是向着频率逐步提高、波长愈来愈短的方向发展,达就要求电子仪器的研究和生产能跟上科学发展的需要。对于微波仪器的另件,诸如:同轴测量彼、调配器、谐振腔、电子腔、波长计、精密衰減等等,要求光洁度和精度愈来愈高;同时这些另件的形状也愈来愈复杂,因而对于微波另件的加工和工艺的要术也就更高了。达就要求我们对微波工艺和加工的研究工作能跟上无线电电子学发展的需要。最近我们加工的一个“吸收体”另件,是“吸收塑料”,达是近几年的新材料,加工时容易破裂,特别是另件的口部薄,最容易坏。针对这种情况,我们学习了毛主席关于 A preface Modern radio electronics is toward the gradual increase in frequency, the shorter the wavelength of the direction of development, up to the requirements of electronic equipment research and production to keep up with the scientific development needs. For other parts of the microwave instrument, such as coaxial measurement, adapter, resonator, electronic cavity, wavelength meter, precision attenuation, etc., require higher and higher finish and accuracy; at the same time the shape of these parts also more and more Complicated, so for microwave processing and processing of other components will be higher. The requirements of our work on microwave technology and processing research to keep pace with the development of radio electronics needs. Recently, an additional piece of “absorbent body” that we process is “plastic absorptive”, which is a new material in recent years. It is easily broken during processing. In particular, the other parts are thin and the most vulnerable. In response to this situation, we learned about Chairman Mao
