短帶開關
英文
broken tape sweitch-
The usual method to broaden the bandwidth of the pin diode switch is combining the pin diodes with stub filters : when under reverse bias, the didoe is part of the filter, the transmission bandwidth is broadened ; when under forward bias, the structure of the filter is destroyed, signal is isolated
Pin二極體開關展寬頻帶的方法一般是把pin二極體結合進短截線濾波器，使pin二極體在反向偏置時作為濾波器的組成部分，以展寬開關在傳輸狀態下的頻帶；當二極體正向偏置的時候，濾波器的結構被破壞，起到隔離的作用。The following are the results from the unreasonable utilization for the city area : food producing become more difficult because of the excessive declining of farmland ; management of the land resources turn to be unmarketable and the land is fallowed and wasted ; the ecological crisis could be aroused and the exist and development of the city be threaten because of the destroying of the ecological balance ; the improvement of social economy and quality of people ' s life is seriously banned by the unnatural shortage of the land supply, or the abnormal increase of the land price ; the outline of a city could n ' t be impressive, or the aesthetic value could n ' t be carry out on account for the monotony in the city ' s construction, etc. too much lessons show that we must pay more attention on the research of the utilization of the city ' s land in order to make scientific, forecasting and reasonable principles, laws and policies to regulate activities for people planning and exploiting city land
對城市土地不合理利用的後果是：或造成耕地大量被侵佔，給糧食生產帶來危機；或造成土地資源的大量閑置和浪費，引起土地資源配置的非市場化；或造成生態環境失衡，引發嚴重的城市生態危機，危及城市未來的生存與發展；或導致城市土地供應的人為短缺及房地產價格的畸形高漲，嚴重阻礙經濟增長和人民生活質量的改善；或城市土地結構趨同，缺乏鮮明的個性和特點；或城市土地上的工程都千篇一律，難以樹立城市形象，難以體現美學價值等等。理論和歷史教訓警示我們，土地資源是人類社會可持續發展的基礎，必須切實加強對城市土地利用的研究，制定出具有前瞻性、科學性和實踐性的與城市土地利用相關的法律、法規和政策，以規范人們的用地行為，指導城市規劃、土地開發等實踐活動。Saturating logic draws large fast current spikes from its supply during switching and, having noise immunity of hundreds of millivolts or more, has little need of high levels of supply decoupling
晶體管在開關過程中會流過短暫的大電流（帶來噪聲） ，但是數字電路的噪聲容限可達數百毫伏，所以對電源去耦的要求不高。Based on the advantage of the solid - switch, many fcls with solid - state switch have been proposed. fcl with series compensation which could limit the fault current and also make compensation is more flexible and practical when compared to the others. in this paper, a type of fault current limiter with series compensation is studied
基於此，研究者提出了各種不同拓撲結構的採用固態開關的故障限流器，其中，帶串聯補償的故障限流器，既具有串聯補償的功能，又能根據短路的實際情況改變限流程度，因而具有較大的靈活性和實用性。Based on adaptive transmission, in this paper, several key technologies are studied on the wide - band wireless digital communications. the basic idea is to decrease system spending, optimize the whole system performance, reduce computation complexity, shorten transmission delay, improve the real - time processing capability, and cut cost
本文基於自適應傳輸的思想，對寬帶無線數字通信中的關鍵技術進行了研究，力圖節省系統開銷，從整體上優化系統性能，降低計算復雜度，縮短傳輸時延提高系統的實時處理能力，節約成本。分享友人
