如果可以弄到更长的垂直导压管，就定位安装座，将其80%上行、20%下行。
If longer lengths of straight run are available, position the mounting such that 80% of the run is upstream and 20% is downstream.
如果支撑设施不够完善，应使用通道、角铁、导管或管道对单独导压管进行连续支撑。
Where this facility is not available, individual tube runs shall be supported continuously in channel , angle iron , conduit or pipe.
采用P型栅压自举开关补偿技术，可以有效地克服采样管导通电阻变化引入的非线性失真，提高采样精度。
By compensating with P-type bootstrapped switch, this circuit can overcome nonlinear distortion, which is generally introduced by signal-dependent on-resistance, and improve sampling resolution.
由于静电计、安培计或皮安计的输入端压降小于1mV，这两个二极管不会导通。
Since the voltage burden of the electrometer ammeter or picoammeter is less than 1mV, the diodes won't conduct.
晶闸管逆变弧焊电源具有单管导通电流大、耐压高、正向压降低、过载能力强等特点，但在使用过程中会出现各种故障。
Thyristor inverter welding power source with single-conduction high current, high breakdown voltage, low positive voltage drop and the high over load etc.
