The objective of design optimization for the current loop is to maximize the cross-over frequency. The results show the stability is improved and the capability of suppressing the switching noise is far better than the original. The objective of design optimization for the voltage loop is to minimize the gain of the line ripple voltage.As a result the bandwidth minishes obviously and optimization design excelles in restraining the ripple.

主电路以总体积最小为优化目标，优化结果表明电路的体积减少了0.5%；电流环以开环穿越频率最大为目标，优化结果表明电流环的稳定性能得到了改善，开关噪声抑制能力明显优于优化前的；电压环以线纹波电压增益最小为目标，优化结果表明电压环的带宽明显减小，纹波抑制能力远远优于优化前的。

Three types of modulators are available, which differ according to the bandwidth(6,7orMhz).

By adding the Presentation Interlayer and the Logic Interlayer from the point of view of logical level, the system can pool large numbers of computing and net flow onto agent-server side, so it can not only minimize transmission data between the browser and embedded facilities'gateway, and save the limited bandwidth but also improve the response time.

从逻辑层次上该系统通过增加表示过渡层和逻辑过渡层将大量的计算和网络流量集中于智能代理-服务器一边，从而减轻了嵌入式设备的计算负担，减少了浏览器到嵌入式设备网关之间的数据传输、节约有限的带宽、提高了响应时间。

There are a lot of public and private torrent tracker sites on the Internet that does not always open for free registration, but often features a lot of fast seeders, best downloadable contents and extreme fast download speed which may max out ADSL bandwidth limit.

有很多公共和私人洪流跟踪上网际网路的网站，这并不总是开放免费注册，但往往功能很多快速seeders ，最好的可下载的内容和极端快速的下载速度可能的最大的ADSL带宽的限制。

It causes companies financial losses because they have to purchase more high tech software like spam blockers and spy-ware removers, and it's a strain on system servers and bandwidth.

公司造成经济损失，因为他们喜欢购买更多的高科技软件、垃圾邮件阻断间谍用品油剂、它的带宽和服务器系统的压力。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
