转换器

The principle, system design and test method of a displacement changer was introduced, which is used to measure axial remotion magnitude etc.

该文介绍测量轴向移动量的位移转换器的原理、系统设计及校验方法。

The main features of the system are: the communications line is not only used for data transmission but also responsible for the system control and management; only one analogue to digital converter is needed for the whole system; a digital trimmer which is analogous to the adjustable resister in function is installed to each sub—system.

本文所进行的数字型条干均匀度测试仪的系统设计，采用了多微处理器的分布式并行结构，提出了一种数字信号的总线结构，采取了数据预处理和数字微调等措施，其主要特点为：半双工异步通信线不但用于数据传输，而且还负责系统的控制和管理；整个系统只需一路模数转换器；各子系统均设有数字微调装置，其功能类似于模拟电路中的电位器，可独立进行参数调整。

Sample and hold circuit is an indispensable important circuit block, which almost determines the performance of the whole A/D converter.

采样保持电路作为模数转换器的必不可少的关键单元，很大程度上决定了ADC的性能。

A high performance CMOS sample and hold circuit for use in the front end of a l2bit 100MS/s ADC is presented.

介绍了一种用于12bit，100MS/s流水线模数转换器前端的采样／保持电路的设计。

Later, in order to provide a semantical model for the program withprobability choice, many researchers research the probabilistic predicate transformers.

后来，研究学者为了给带有概率选择的程序提供语义模型，提出概率谓词转换器。

Connections come courtesy of a 9-pin serial control cable via RS232 to RS485 converter.

连接来提供一个9针通过RS232串口控制电缆的485转换器。

This timing is done by the SOFTWARE used to CONTROL the serial PORT and not by the converter.

这个时序不是由转换器完成的的而是由控制端口的软件完成的。

The Apollo acquisition is an important step forward in our vision of becoming a full-sector sheeter supplier covering the entire market from mills to small converters," stated Steve Brimble, MarquipWardUnited sheeter sales leader and managing director of the Apollo product line."

太阳神收购迈出了重要的一步扩大我们的视野，成为一个完整的部门切纸机供应商，覆盖了整个市场从工厂到小转换器，说："史蒂夫布林布尔，MarquipWardUnited切纸机销售领导人及董事总经理的阿波罗产品行。"

Because a bulk smoothing capacitor is usually installed on the DC side of many AC to DC converters, the characteristics of harmonic loads will be influenced by this capacitor. Nowadays, shunt active power filters can't reduce harmonics effectively for this voltage type harmonic-producing load. Therefore, a series active power filter is designed to meet the requirements of voltage-sourced harmonic loads. Both source current and load voltage are detected in order to reach the compensation voltage for the SAPF.

由於许多交直流电源转换器均在直流端并联一直流电容以作为稳压之用，此大电容将造成负载谐波特性的改变；此类谐波源负载，如果使用现今常见的并联型主动式电力滤波器并不能很有效解决此类谐波问题；因此本文将采用串联型主动式电力滤波器，并配合同时量测电源电流及负载电压的混合式控制模式，即可有效解决此类谐波问题。

Growing from the forming of flame combustion process and plant of the snow flake, one can all realize the existence of chemical meaning. Moreover, one can find the world to be profound to reach, observe fixed star and evolve theory examine, and even as small as plastic bag, wash bowl precise, catalyst converter, nanotech material in detail.

从雪花的形成、火焰燃烧过程以及植物生长等，都可体会到化学意涵的存在，甚至大到发现世界奥妙，观测恒星和演化论推究，小到塑胶袋、洗碗精、触媒转换器、奈米材料中都可一窥其境。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
