The labels " analog ground " and " digital ground " on these pins refer to the parts of the converter to which the pins are connected , and not to the system grounds to which they must go 引脚标记说明该引脚已连接到芯片内部的哪个部分,并非要把该引脚连接到电路的哪个参考点。
Ultimately , a 3d demo system is established based on the browser / web server mode , which provides a feasible method to found a flight simulation system ground on internet 本文最终建立了以浏览器/ web服务器为基础的三维飞行演示系统,为建立基于internet的飞行仿真系统提供了一种可行的方法。
Japan - like recession : much like japan in the early 1990s , unable to figure out just what assets are bad and which institutions are tainted , the whole system grinds on slowly working through these problems 日本式萧条:很像上世纪90年代的日本,无法明确指出哪个资产不好,那些机构有问题,整个系统带着这些问题缓慢地进行。
This paper mainly studies the electri - hydro servo system of a certain airplane ' s steering system and the construction of the landing gear system ground simulator computer control system of this airplane , including hardwares and softwares 本文主要对国产某型飞机的起落架地面模拟器计算机控制系统的硬软件构建及其操纵系统的电液位置伺服系统的特性分析进行介绍。
