observer eye
解釋
觀測透鏡,目鏡-
The spectacle of the aurora may appear to dazzle and enchant the observer's eye.
極光的壯麗景色的出現，會使觀察者為之眩目和迷惑。 -
And as for the vague something - was it a sinister or a sorrowful, a designing or a desponding expression ? - that opened upon a careful observer, now and then, in his eye, and closed again before one could fathom the strange depth partially disclosed ; that something which used to make me fear and shrink, as if i had been wandering amongst volcanic - looking hills, and had suddenly felt the ground quiver and seen it gape : that something, i, at intervals, beheld still ; and with throbbing heart, but not with palsied nerves
至於那種令人難以捉摸的東西那種表情是陰險還是憂傷，是工於心計還是頹唐沮喪，一個細心的旁觀者會看到這種表情不時從他目光中流露出來，但是沒等你探測暴露部分的神秘深淵，它又再次掩蓋起來了。那種神態過去曾使我畏懼和退縮，彷彿徘徊在火山似的群山之中，突然感到大地顫抖，看到地面裂開了，間或我還能見到這樣的表情，我依舊怦然心動，卻並未神經麻木。 -
Put down the name of the observer, the place and time of observation, duration of observation, cloud cover, the sky s limiting magnitude the magnitude of the faintest star you can see with the naked eye and the number of meteors observed on the data sheet
流星雨的觀測資料，只要清楚註明觀測者姓名觀測地點觀測時間觀測長度雲量最暗可見星等及流星數目，便已經是一份十分有科學價值的觀測記錄了，很簡單，對嗎？ -
Indispensable for the observer is a good star atlas, containing all naked eye stars.
觀測者必須具備一份包括肉眼能看到的所有天體的好星圖。 -
Aim at the dtc ' s blemish mentioned above and the direction of dtc technique development, the dissertation put great emphasis on the work as follows, with an eye to exalt dtc system function : ( 1 ) a new speed - flux observer of an induction motor is proposed to enhance the accuracy of flux observing, which is an adaptive closed - loop flux observer and different from the traditions. a new adaptive speed - observation - way is deduced out according to the popov ' s stability theories ; ( 2 ) to improve the performance of dtc at low speed operation, we have to exalt the accuracy of the stator flux estimation and a new way of bp neural network based on extended pidbp algorithm is given to estimate and tune the stator resistance of an induction motor to increase the accuracy of the stator flux estimation ; ( 3 ) digital signal processor is adopted to realize digital control. an device of direct torque control system is designed for experiment using tms320lf2407 chip produced by ti company ; ( 4 ) bring up a distributed direct torque control system based on sercos bus, sercos stand for serial real time communication system agreement which is most in keeping with synchronous with moderate motor control ; ( 5 ) the basic design frame of the hardware and software of the whole control system is given here and some concrete problem in the experiments is described here in detail
針對上面提到的直接轉矩控制的缺陷和未來直接轉矩控制技術發展方向，本論文重點做了以下幾個方面的工作，目的在於提高dtc系統的綜合性能： （ 1 ）提出一種新型的速度磁鏈觀測器，新型的速度磁鏈觀測器採用自適應閉環磁鏈觀測器代替傳統的積分器從而提高磁鏈觀測的精度，並且根據popov超穩定性理論推導出轉速的新型自適應收斂律； （ 2 ）改善系統的低速運行性能，主要從提高低速時對定子磁鏈的估計精度入手，提出了一種提高定子磁鏈觀測精度的新思路? ?利用基於bp網路增廣pidbp學習演算法來實時在線地修正定子電阻參數； （ 3 ）採用數字信號處理器dsp實現系統全數字化硬體控制，結合ti公司生產的tms320lf2407晶元，設計了直接轉矩控制系統的實驗裝置； （ 4 ）提出了基於sercos總線網路化分散式的直接轉矩控制系統， sercos （ serialrealtimecommunicationsystem ）是目前最適合同步和協調控制的串列實時通信協議； （ 5 ）基本勾勒出整個控制系統的硬體和軟體設計基本框架，詳細描述一些實驗中的具體的細節問題。 -
We then specify where the observer s eye will be located. the ray tracing program will mathematically model the objects, the light rays and the observer and compute the colour for each pixel on the screen
光線追蹤的程式會利用數學模型模擬物件光線及觀察者之間的關系，從而計算觀察者在電腦屏幕上應看到的影像。 -
