查询词典 pulses

The principle of telegraphy is simple: Pulses of electrical current are sent through a wire by manually tapping on a key to operate a simple switch.

电报机的原理很简单。用按键来操纵一个开关，然后就在导线中就产生了电流脉冲。

Each letter of the alphabet, and numbers 0-9, is represented by a unique pattern of dots and dashes, which are transmitted electronically as short and long pulses by a person using a telegraph key.

每个字母和数字0-9 ，代表的是一种独特的模式点和破折号，这是电子方式传送的短期和长期豆类的人使用电键。

The body constitution often more leans. Deep-red tongue often occurred; reddened top tongue also could be seen. The coats were thin and white or thin and yellow. The pulses were thready or thready and feeble.

临床观察发现此类患者往往形体偏瘦，舌暗红较多，也有舌边尖红者，苔可见薄白苔或薄黄苔，脉往往表现为细或细弱脉。

In this respect, PCM bears little resemblance to these other forms of signal encoding, except that all can be used in time division multiplexing, and the binary numbers of the PCM codes are represented as electrical pulses.

由这点来说，PCM、PWM 和 PPM 除了三者都能用於 TDM 上，以及 PCM 的确将它的代码表回脉冲以外，PCM 和它的前辈们确实很不相像。

The time interval between start pulses is equal to the signal accumulation time.

启动脉冲之间的时间间隔是相等的信号积累的时间。

Pulses on ON/OFF less than tOFF are ignored, offering glitch immunity.

对脉冲开/关比托夫少被忽略，提供无干扰。

Beginning with wave equation, the paper has deduced the propagation of gauss pulses in single mode fiber and fiber grating transmission compensation. The characteristics of cascaded phase-shift gratings are discussed by numerical simulations of coupled-mode theory and T-matrix method. The experimental works and measurement results are shown in this paper. On the other hand, we have introduced the basic theory of EDFA and figured out the characteristics for EDFA at different conditions by numerical simulation. Some experimental results for EDFA are also presented here. In this article, you can find the influence on Optical Fiber Amplifier by Gain Tilt, especially, the negative effect on CSO in CATV transmission system.

论文首先从波动方程入手，对高斯脉冲在单模光纤中的传播演化及光纤光栅透射补偿进行了详细的研究；较系统地介绍了光纤光栅的耦合模理论，并将传输矩阵计算法用于计算级连相移光纤光栅的光学特性；重点介绍了作者在光纤光栅刻制及特性测量方面所做的一些实验研究工作；较系统介绍了EDFA的基本理论，计算出各种条件下EDFA的光学特性，并进行了一些实验研究；综合分析光纤放大器对光纤传输系统的影响，特别分析了光纤放大器增益不平坦对光纤CATV系统中CSO恶化的原因及其解决方法，并研究了光纤布拉格光栅在稳定980nm泵浦源输出功率和输出波长方面的应用；结合一个基于光纤光栅和光纤放大器的光纤用户接入网方案，对光纤用户接入网的若干问题进行了理论与初步的实验研究。

You can use a clamping circuit instead of a Schmitt trigger to clean up high-frequency input pulses.
