The engineering ethics in the united sates : consisting of " microethics " and " macroethics " in contents and objects ; bringing engineering ethics into an education system through three kinds of curriculum models for engineering ethics education those consists of stand - alone engineering ethics course, across technical course and across non - technical course ; changing the teaching direction by the abstract preachment of morals theories to practice analytical case teaching, and paying attention to the development of the teaching resources and the usage of the internet
摘要美國工程倫理教育，在內容與目標上包括關注個體職業責任問題的「微觀倫理」和關注工程整體發展責任問題的「宏觀倫理」 ；課程上以獨立工程倫理課程、工程倫理與技術課程整合、工程倫理與非技術課程整合三種模式將工程倫理成分納入工程教育體系中；教學上由道德理論的抽象說教轉向實踐分析的案例教學，並注重教學資源的開發和網際網路的使用。 -
" anyway, " he continued, with the smoke drifting in the direction of the fireplace, " this chap could stand it no longer and subsequently decided to take his own life by shooting himself in the head with a pistol
「最後， 」他繼續講著，吐出的雪茄煙霧向著壁爐的方向飄去「那傢伙再也受不了，就飲彈自盡了，現在有謠言說他的鬼魂就在那房子里出沒。 」 -
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。 -
The gas layers are controlled by the faults in the direction east and west in the plane, and in the direction of north and south the connectivity is somewhat better, the wells of connection become more and the gas layers stand in the high place of structure
氣田內氣層平面上東西向受斷層控制，南北連通性略好，連通井數多，且多分部在構造高部位。總體來講，八屋氣田具有氣層多，縱向上分佈較連續、橫向上分佈不穩定的特點，東西向主要以斷層隔擋，南北向受巖性制約。
