查询词典 keyboard input

The readout system can efficiently reduce the influences from leakage current, input offset, process parameter instability, and other causes. The value of input weak current signal can be obtained simply through demarcation.

读出电路系统可以有效地减小漏电流、输入失调、外来干扰和工艺参数不稳定等带来的影响，通过简单的标定和换算即可得到微弱电流信号的大小。

Note that the input offset current can be partially nulled by enabling the INSTRUMENT current suppress with the input terminals disconnected and ZERO CHECK open.

要注意，在仪器电流抑制的条件下，即输入端不连接和"ZERO CHECK"开路时，输入失调电流可部分无效。

This system is designed based on SPCE 061A microcontroller to measure the close loop parameters of the amplifier. The system can measure the input offset voltage、the input offset current、the open loop AC differential mode voltage gain、the AC common mode rejection ratio and unit gain bandwidth,using the measure method of assistant amplifier. What is more, data printing is completed in this system.

摘要本系统是基于SPCE 061A 单片机的运算放大器闭环参数测试系统，该系统采用辅助运放测试方法，可对运放的输入失调电压、输入失调电流、交流差模开环电压增益和交流共模抑制比以及单位增益带宽进行测量，并具有将测试数据打印输出的功能。

At an input resistance of 1 M relative to the ground, the input signal is not grounded.

此输入端的输入阻抗为1M，而输入信号则为接地。

An electrometer preamplifier is used at the input to increase sensitivity and raise input resistance.

在其输入端采用一个静电计前置放大器以提高灵敏度并提高输入电阻。

Because its condition is obtains by input refurbishing, therefore, it reflects is the input state.

由于它的状态是由输入刷新得到的，所以，它反映的就是输入状态。

The signal identifying unit receives an input signal and identifies the type of input signal that is received.

所述信号识别单元接收输入信号并识别所接收的输入信号的类型。

For taking the input, the unit does nothing of efforts but just accepts an input and does not modify it.

采取的输入，该单位即努力无关，而只是接受一个输入，不对其进行修改。

So the growth of economic output can be directly summed up in two parts: First, the growth of input, second, the growth of output per unit input, namely the growth of productivity.

所以增长的实现直接归结为两部分：一是投入的增长，二是单位投入的产出的增长，即生产率的增长。

Power meter measure true power by multiplying the instantaneous input voltage and input current, the product is then averaged out.

功率表是通过将瞬间的输入电压和输入电流相乘﹐然后取平均值来得到真实的输入功率。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。

On one hand, there are discussions with the works council and union about extension of short time working up to the end of September.

一方面，有讨论，工程理事会和联盟关于延长工作时间短至9月底。
