查询词典 ammeters

Electrometer ammeters and picoammeters and methods of making low current measurements were described in Sections 1 and 2 respectively.

第一章和第二章已经分别对静电计和皮安表以及弱电流测量的方法等问题进行了介绍。

The former circuit in experiments of revising ammeters with box electricity potential difference meter s can only revise an ammeter, but can not measure the interior resistance of the ammeter at the same time, which can be overcome with the improvements on the circuit.

原有箱式电势差计校正电表实验线路往往只能校正电表而不能同时测量电表的内阻，通过对电路加以改进可以克服这些缺点。

Now we can produce various capacitors professionally,such as AC,DC, pulsating and metallized films capacitors,which are used in Communication Equipments, Exactitude Instruments,Television,Display,Electromotion Tools, Motors, Rectifier for Lamps, Electronic Portfire, Electronic Ammeters, and etc.

Part 2: Special requirements for ammeters and voltmeters

第2部分：电流表和电压表的特殊要求

So it is used instead to calibrate more practical current-measuring instrument, called ammeters.

因此，它只用于校准更实用的测量电流的仪表――安培计。

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

然而，实际的安培计在输入端开路时的确有一些小的电流。

This is the case, you need to observe the offset press control cabinet in ammeters pointer changes.

呈现这种环境，必给查察胶印机电气柜边的电流表指针的改变。

The key problem to work out the electrical data acquisition system is how to establish the communication link between the FMU and ammeters and make sure the system can get the data in ammeters and run without failure.

电力数据采集系统实现的关键技术就是如何建立集中器和电表之间的通信链路，使系统对电表的数据采集能够正常进行。

There are various means to realize the communication link between FMU and ammeters, such as Ethernet and PLC, however they all have different limitation. We would take advantage of radio frequency in ISM channel to provide a better solution in the communication between FMU and ammeters.

集中器与电表之间的物理链路可以有很多选择，如以太网，电力载波线等，但它们都存在着一定的缺陷，所以我们采用了公用ISM频段的无线通信方式来实现集中器与电表之间的数据通信和采集，这种技术有很多优点，它无需布线、成本低、传输速度快、可靠性高。

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。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
