对广大供电企业来说，用户功率因数的高低，直接关系到电力网中的功率损耗和电能损耗，关系到供电线路的电压损失和电压波动，而且关系到节约电能和整个供电区域的供电质量，这是众所周知的道理。提高电力系统的功率因数，已成为电力工业中一个重要课题。文中简要集中探讨了影响电网功率因数的主要因素以及低压无功补偿的几种实用方法，和确定无功补偿容量从而提高电力系统功率因数的一般方法。
For the majority of power supply enterprises, the level of user power factor, is directly related to the power loss and power loss in the power grid, related to the voltage of the power supply line losses and voltage fluctuations, but also to save energy and supply area for electric quality, this is a well-known truth. Improve the power factor of the power system, the power industry has become an important topic. Briefly several practical approach focuses on the main factors affecting the grid power factor and low voltage reactive compensation, and determine the reactive power compensation capacity of the general method to improve the power factor of power system.

Debug－PC之开山老祖
Debug 原意是杀虫子。这里是机器调试工具。
其实，Debug的由来，还有一则趣闻，在早期美国的一计算机房中，科学家正在紧张的工作。同时，许多台大型的计算机也在不停的运行着。大概是由于，机器过热，引来许的小虫子，以至于，计算机无法正常运行。科学们，只好停下来，捉虫子...虫子捉完了，计算机运行也正常了，后来，这个名词就沿用至今了....
虽然，现在好的软件越来越多了，但是有些，我们只需动手，用Debug就可解决，且快而好！接下来，我们就一起学习Debug在各方面的运用吧！（在杀毒、加解密、系统...）下面我和大家一起学习一些，Debug的用法，虽然，现在好的软件越来越多了，但是有些，我们只需动手，用Debug就可解决，且快而好！
