We reject this model in favour of including everyday practices, and doing so without endorsing or prioritising textual traditions, high status practices, or capital cities and tops of hierarchies in general, in order to see the work of transmission at all levels and how, or if, they work together.

然而，我们舍弃了这个方法，而是将日常的物质实践也包括进来，并不优先考虑整体性研究文本传统、高等级实践、都城、以及阶序中的高等级。我们的方法可以研究各个层次的传递，以及传递的方法，或者它们是否共同作用。

In neural transmission experiment shows that the greater the stimulus intensity to stimulate the higher the frequency of nerve impulses, high frequency extremely low frequency rejection, for nerve inhibition; light stimuli at low frequency, for the nerve on the weak signal, there are complementary role.

在神经传输的实验中证明，刺激力度越大，激发神经脉冲的频率越高，高频率极易抑制低频率，对于神经有抑制作用；轻刺激产生低频率，对于神经上的弱信号，有相辅相成的作用。

However, according to the operation of"GZB-SNQ and TSQ-GBJ HVDC project", reliability of Circuit Protection Device of domestic and international HVDC lines is not high, within easily disoperation and other issues. So how to improve reliability of HVDC transmission lines is urgently needed to solve in our country's development of HVDC.

然而根据葛上直流输电工程和天广直流输电工程的运行情况来看，目前国内外投运的直流线路继电保护装置普遍存在着可靠性不高，易误动等问题，因此如何提高直流输电线路保护的可靠性是我国发展直流输电亟待解决的问题。

In addition, there are two strands of the head is also black, and are rust, rust can be seen because of lead wire resistance increases, resulting in the signal can not be smooth, telephone through the audio signal, the low band signal can also only phone, there is always the voice of flap, and the use of the ADSL band signal is relatively high, head through the rust on it is very difficult, leading to slow or stop signal transmission.

此外有两处绞合的线头处也发黑了，都是锈，可见正是因为导线生锈导致电阻增大，导致信号不能畅通，电话通过的音频信号，频带低，信号还能通过，只是电话里老是有啪啪的声音，而ADSL的信号使用的频带比较高，线头生锈了就很难通过，导致信号传输变慢或者断流。

Featuring wider angle views than predecessors, a new "super achromatic" objective lens,"Phase Corrected" Abbe-Koenig prisms, light transmission of at least 91%, and nitrogen filled composite housings reinforced with fiberglass to assure high endurance. In September 1994 Zeiss announced the first "Contax" 35mm rangefinder camera with interchangeable lenses made since 1959; the "G1" features include auto focus with any of four optional lenses, TTL metering, automatic film advance of up to 2 frames per second, and a luxurious titanium body.

这些新品体现了公司技术成就的最新进展，拥有较以前产品更宽的视角，新型&超消色差&物镜，&相位修正&阿贝-科宁棱镜，至少91%的透光率，充氮加固玻璃纤维复合镜室，以确保产品的耐用性。1994年9月，蔡司又推出了自1959年以来的首款镜头可互换型&康泰克斯&35mm连动测距对焦相机；此款&G1&型相机包括自动对焦功能和可任选的四个镜头，晶体管逻辑电路测距（TTL，晶体管逻辑电路），每秒高达两帧的自动卷片功能，和豪华钛机身外壳。
