Examples
- It is applicable for both direct and comparative measurements of outer and inner dimensions of workpieces such as parallel planes , spheres , cylinders and bores
主要用于对平行平面状，圆柱状，球状类精密量具和零件的外形，内孔、尺寸的测量。 - Secondly , with the demands of monitoring plant water potential in mind , the apparatus has been tested with satisfactory results thirdly , utilizing that testing apparatus and nacl solutions at 20 c , a study is preformed to investigate the on - line non - invasive automatic monitoring technique of plant water potential , with some models of monitoring plant water potential properly established . results show that the second model of monitoring plant water potential is desirable after comparing . then , comparative measurements are done with kc1 solutions , using both the testing apparatus and the commercial wescor water potential meter
利用所设计的试验装置和不同浓度的氯化钠溶液进行在线无创伤自动监测植物水势的试验研究分析，并建立了一些监测植物水势的模型，经过比较分析，确定最优地能实现在线无创伤自动监测植物水势的模型；然后运用此模型对不同浓度氯化钾溶液的水势进行测定，以及与美国wescor公司生产的植物及土壤水势测定仪进行比较测试试验，通过对这些比较验证试验的分析，认为此模型在植物水势在线无创伤自动监测方面具有其可行性。 - The comparative measurement method for vacuum gauge calibration is introduced . the construction , principle and process of the calibrator are described . the effects of six kinds of gas on the calibrated ionization gauge are explored and relative sensitivity is obtained . the necessity of the calibration on the vacuum gauge and instrument is proved by the research
文章介绍了对真空规管和仪器进行校准的比对法,阐述了校准系统的结构、原理及校准方法;探讨了被校电离规在6种不同的气体中的校准效果及校准前后的差异,说明了气体歧视效应的存在和影响,得出了各气体的相对常数;结果表明,对真空规管及仪器进行校准是必要的。
