This paper is consisted of two major parts : one deals with the general working performance of the fmghp by setting up mathematic model and developing computer procedure, getting the datum related to the capillary flow and heat transfer, analysing the working characteristics of fmghp in different working temperature, heat flux and inclination angle etc. in this part, the prediction of capillary and boiling limit are also included. the other major part studies the flow and heat transfer characteristics in the micro - film region formed by the meniscus attached on the metalic fin in the micro rectangular groove. investigations on the influence of width of groove and other factors on heat transfer in this region have been made. the importance of this micro - region in the heat transfer of the entire heat pipe has been unveiled. the heat transfer characteristics gotten by this research could be used in design and application and also optimization of this kind of fmghp
本文在大量查閱現有國內外文獻的基礎上，總結並綜合前人有關微槽平板熱管理論研究方面的成果，對單面刻有槽道的微槽平板熱管進行了較為深入和細致的研究。本文的研究共分兩大部分，其中第一部分考察了該型熱管的整體工作表現，通過建立數學模型和開發相應的計算程序，得到了熱管內部毛細流動和傳熱的數據，分析了熱管在不同工作傾角、不同加熱熱流以及不同工作溫度等情況下工作特性的變化規律，考察了汽液界面上的剪切作用對熱管傳熱量的影響，並且進一步在理論上預測了該型熱管的毛細和沸騰極限。 -
The tests of e - o applications by our flux ktp has been realized, the results showed : optical waveguides fabricated by using an ion - exchange process, which have an exchange - ion concentration depth profile and refractive - index profile, is close to a complementary error - function distribution, optical homogeneity and device thermal stability is much better. amplitude modulation switch formed by our flux ktp has the contrast ratio of 150 : 1 and insert loss is 2. 5 % at 1064 nm. high quality optical pulse with 1 ns width was cut successfully by using an e - o modulator from a laser pulse with 50 ns width, this modulator had run for three years, and the crystal did n ' t blackened, it showed our low conductivity flux ktp can endure high modulation voltage for a very long time
Ktp晶體的電光應用試驗表明：用離子交換法製作的電光波導，其離子交換濃度、折射率變化符合餘弦誤差函數，光學均勻性以及器件的溫度穩定性較好；製作的強度調制電光開關，消光比為150 ： 1 ，對1064nm激光的插入損耗為2 . 5 ；製作的電光調制器用於激光脈沖整形試驗，從脈沖寬度50ns的激光脈沖削出脈寬1ns的高質量光脈沖，該電光開關經過長達三年多的使用，沒有出現晶體變黑現象，說明本實驗的低電導率ktp晶體能夠耐受長時間的調制電壓。 -
The direct torque control theory is a kind of new control method after vector control theory in ac control field. it calculates and controls the torque and the flux of ac electromotor in stator coordinate using the voltage space vector. adopting the stator magnetism field direction method, it recurs to discrete pang - pang control producing pulse width modulation signal and controls the switch state of the transductor when better quality steady - state performance is produced
直接轉矩控制技術是繼矢量控制技術之後交流調速領域中新興的控制技術，它採用空間矢量分析的方法，直接在定子坐標系下計算並控制交流電動機的轉矩和磁鏈，採用定子磁場定向，藉助于離散的兩點式控制產生脈寬信號，直接對逆變器的開關狀態進行最佳控制，以獲得轉矩的高動態性能。
