Also , we calculated the risk ratio of malalignment of > 3 and > 2 and the complication rates with both procedures 同时,我们计算了> 3和> 2的力线不良的危险比和两者手术步骤中的并发症发生率。
Radio interference characteristics of overhead power lines and high - voltage equipment ; part 2 : methods of measurement and procedure for determining limits ; identical with cispr 18 - 2 : 1986 架空线力线和高压设备的无线电干扰特征.第2部分:测量
In order to solve the problem of measurement - control signal communication in situation , we propose a detail project that the lonworks technique is transplanted to high - voltage power line in this paper 为了解决特殊情况下的测控信号传输问题，本论文提出lonworks技术向高压电力线移植的具体方案。
The main conclusions are as follows : first of all , applying the conception of flux lines to the theory of electromagnetic field makes abstract electrostatic field visible and intuitive 主要内容和结论可归纳如下:首先,电磁场理论由于引入了力线的概念,从而使得非常抽象的静电场获得了形象化的直观表达。
We use rogowski coil as the sensor that mounted on high voltage power line . after converting rogowski coil ' s analog signal to digital signal , we transmit the digital signal to low voltage part through pof where we resume the analog signal and finish the tasks of measurement 采用rogowski线圈作为高压电力线上的传感头，将rogowski线圈的输出数字化后，通过光纤传送到低压端恢复成原来的模拟信号，实现对高压电力母线电流的测量。
Carrier communication over high voltage power line has been developing for near one hundred years . it has many applications for voice communication in power distribution , data collection from tele - control instrumentation , and so on . however , using power line within one transformer area to provide internet access is a just recent development 高压电力线载波通信已有近百年的历史，它在电力调度话音通信、电力系统远动装置数据采集等方面取得了卓有成效的应用，但是利用一个台区的低压电力线建立internet接入网是近几年来国际上刚刚兴起的技术。
This article describes the plc ’ s using enviroment and the users ’ needs in details , and then tells the differences between the dplc and the troditional plc . it also describes how to decimation and compress the tele - voice , how to deal with the data tunnels , and the multiplex data through the the line which ’ s bandwidth is changeable between 10 . 8bps and 28 . 8kbps this project uses the programmable vopp chips , the cpld for bus controlling , the fpga and the mcu with high processing ability . all of these ensure the high ability to process the signals and the operations 本文详细介绍了高压电力线载波机的使用环境和用户需求,全数字电力载波机和传统模拟载波的的差异;按电力调度的需求设计完整的两路语音、两路数据的电力线载波通讯机。详细描述电话语音的采样,压缩;数据通道的处理;及在10 . 8kbps 28 . 8kbps可变线路速率通道上的数据复接处理。从实现方法上看,该项目采用专用可编程vopp语音处理芯片, cpld芯片做为总线控制,大规模fpga集成电路,高处理能力的mcu 。
