In order to improve the precision of the instrument, circuits for precise rectification, double-integral modulas-digit conversion, temperature compensation, in-line sampling and disturbances prohibition are adopted and their performances are also analysed. 为了提高仪器测量精度,采用了精密整流、双积分模&数转换、温度补偿、同步采样和干扰抑制等电路,并对此作了分析。
The principles of organic agriculture are health, ecology, fairness and care. The organic production emphasized on conversion, buffer zone, parallel production, inputs, biological diversity and prohibition of GMOs. 有机农业的原则是健康、生态、公平、关爱,有机产品生产的重点包括转换期、缓冲带、平行生产、投入品、生物多样性以及对转基因的禁止。
The spin conversion of Ps becomes weaker with NiO content exceeding monolayer dispersion capacity, the prohibition effect of Ps formation by crystalline NiO is significant. 当NiO含量超过单层分散量时,Ps的自旋转换逐渐减弱,晶态NiO对Ps形成有明显的禁止效应。
