测量精密度 meaning in English

precision of measurement

Cid - icp - aes has the advantages of high sensitivity , high signal - to - noise and high quantum efficiency , which nearly reaches theoretical limit value of theoretical parts of an apparatus ; it can memorize thousands of spectra lines at the same time . cid - icp - aes is the newest model , and there are still few articles to report analytical character of this type , as this result the optimum of operating condition and the effect of analytical parameters for photometric precision , signal - to - noise and detection limits are studied : r . f . power is 11 sow , nebulizer pressure is 28psi , the measurement time is 3 times and the integral time is 20s
本实验室的光谱仪是当前最新型号的全谱直读光谱仪，这类新型装置分析性能的研究报道较少，因此研究着重分析了参数对测量精密度、线背比及检出限的影响，对仪器最佳操作条件进行了摘要优化：发射功率采用1150w ；载气压力为28psi ，测量次数选择3次，积分时间为205 。
