安培计

In most cases, an ammeter or picoammeter is used to measure current.

多数情况下，安培计或皮安计是用于测量电流的。

In this method, a constant voltage source is placed in series with the unknown resistor and an ammeter.

在此方法中，恒压源与未知电阻和安培计相串联。

He only had some ammeter and an ampoule.

他只有一些安培计和一个安瓶。

Another way to subtract the input offset current from measurements is to use the relative function of the ammeter.

从测量结果中减去输入偏置电流的另一种方法是使用安培计的相对功能。

The LO of the ammeter and the LO of thesource are connected together.

安培计的LO端和电压源的LO端连在一起。

There are two basic techniques for making current measurements: these are the shunt ammeter and the feedback ammeter techniques.

有两种电流测量的基本技术，即分流安培计技术和反馈安培计技术。

If we connect one ammeter to measure the electric carrent flowing into a torch bulb and another one to measure the current flowing out, they each read the same.

如果我们连接一个安培计来测量流入手电筒电珠里的电流，并连接另一个安培计去测量流出的电流，那么两个安培计各自的读数就会相同。

An ammeter is connected in series with the light bulb, with its positive terminal connected close to the terminal of the battery.

把安培计的正负极分别连接至电池组和灯泡。安培计的正极须接向电池组的极。常见家用电器的电流数值。

Practical ammeters, however, do have some small current that flows when the input is open.

在输入端开路时，理想的安培计指示为零，而实际的安培计总有小部分电流流过。

Feedback ammeters with high value sensing resistors in the feedback loop have lower Johnson current noise and thus greater sensitivity than shunt ammeters with lower resistance shunts.

反馈安培计反馈回路中的取样电阻阻值高，其约翰逊电流噪声就比较低，从而比分流电阻值低的安培计的灵敏度更高。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
