電壓源電流源名字上僅差一個字…HE HE.有一些朋友對此不太明白.所以特此說明下…并以軟件仿真…詳細介紹工作原理…以及注意事項….下面就是電壓源和電流的符號…左邊是電流源,右邊是電壓源. 電壓源…電壓源其實就是我們普通經常用的一種電源.比如說電池呀電瓶或自己做的穩(wěn)壓電路.一般屬于電壓源… 電壓源的特性是: 輸出端,可以開路,但不能短路…總而言之電壓源的輸出電壓是恒定的…比如5V 電壓源輸出的電壓就是5V.隨不同的負載會改變電流…比如在5V 的電壓源上加一個1 歐的負載… 流過的電流就是5/1=5A 電流… 如果接的電阻為2 歐.流過電流就等于5/2=2.5A….這個簡單的計算相信誰都會…電流源電流源和電壓源區(qū)別比較大…電流源輸出端不能開路,但可以短路…為什么不能開路呢…HE HE…是因為開路了…電流源輸出的電壓就為無限高了…(實際上電壓也是有一定值的)總而言之電流源的輸出電流是恒定的.不管你負載的大小…就是你短路了.他的電流還是保持不變.改變的是電壓…比如一個1A的恒流源…你接上一個1歐的負載…他輸出的電壓是.1x1=1V 電壓…當你接上一個10 歐電阻的時候…他就是1x10=10V電壓輸出…

In a recent discussion with a system designer, tHE requirementfor his power supply was to regulate 1.5Vand deliver up to 40A of current to a load that consistedof four FPGAs. This is up to 60W of power that must bedelivered in a small area with tHE lowest HEight profi lepossible to allow a steady fl ow of air for cooling. THEpower supply had to be surface mountable and operateat high enough effi ciency to minimize HEat dissipation.HE also demanded tHE simplest possible solution so histime could be dedicated to tHE more complex tasks. Asidefrom precise electrical performance, this solution had toremovetHE HEat generated during DC to DC conversionquickly so that tHE circuit and tHE ICs in tHE vicinity do notoverHEat. Such a solution requires an innovative designto meet tHEse criteria:

摘要: 研究用內腔式HE- Ne 激光器做光源時, 硅光電池實驗中光電檢流計讀數(shù)不穩(wěn)定的現(xiàn)象。利用硅光電池分別觀測在不加偏振片、加上偏振片時內腔式HE- Ne 激光器輸出的光強度, 得到激光經偏振片后輸出光強隨時間而變。利用共焦掃描干涉儀掃描出激光束的各個縱模, 實驗表明, 內腔式HE- Ne 激光器每個縱模的偏振方向隨時間緩慢變化, 引起了實驗中輸出的光強變化。

THE tar file contains tHE following files: ptfsf.c: HEart of tHE perfect TFSF code ptfsf.h: HEader file for same ptfsf-demo.c: FDTD code which demonstrates use of perfect TFSF code. Essentially this program used to generate results shown in tHE paper ptfsf-file-maker.c: code to generate an incident-field file using tHE "perfect" incident fields ptfsf-demo-file.c: FDTD code which uses tHE perfect incident fields stored in a file fdtdgen.h: defines macros used in much of my code Makefile: simple make-file to compile programs Also include are some simple script files to run tHE programs with reasonable values. THE code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). THE program is currently written so that tHE incident field always strikes tHE lower-left corner of tHE total-field region first. (If you want a different corner, that should be a fairly simple tweak to tHE code, but for now you ll have to make that tweak yourself.)
