【摘要】 本文根据微波与金属相互作用产生散射的特性,采用新颖小型微带天线辐射器和对人体无害的、能接收被金属表面散射的微波功率的有耗振子天线,进行各级标准样块粗糙度与微波被散射功率的实验测量研究,设计制作了一套微波测量粗糙度装置。该装置测量R.值的范围为0.01～2.00μm,其测量误差不大于5%。测量速度快,操作简便,成本低廉,具有一定的实用价值,易于推广应用。更多还原

【Abstract】 Based on the principle that the interaction between microwaves and metal surface can produce some scatterance,a new type of midget microstrip antenna and dissipative scillatrs which are harmless to human bodies and can receive the power of the microwaves scattered by metal surface are used in the experiments and researches to find out the relati ns between the surface roughness and microwaves.An apparatus is devised and made to measure the roughness(the range of the measurement of Ra is 0.01-2.00, um).The error of measuring is less than 5%. The apparatus has several advantages: rapid in measuring, convenient in operation, low in production costs and easy in proctical use.The refore it has some practical values.更多还原
