  1. Because of adopting fixed groundwork, position of every observation station is immovability, agility of instrument is poor, singular fixed stand can not meet the need of modern equipment

    由於採用固定地基的方式，各觀測點的位置不動，儀器設備的機動性差，單一的固定站點已不能滿足現代化的裝備要求。
  2. But as i had no instruments to take an observation to know what latitude we were in, and did not exactly know, or at least remember what latitude they were in ; i knew not where to look for them, or when to stand off to sea towards them ; otherwise i might now easily have found some of these islands

    過去我曾到這一帶的海岸來過一次，知道加那利群島和維德角群島離大陸海岸不遠。但船上沒有儀器，無法測量我們所在地點的緯度，而且，我也已不記得這些群島確切的緯度了，因此也無法找到這些群島，也不知道什麼時候該離開海岸，駛向海島。
  3. Based on the observation data obtained from 69 sampling sites of different age class forests, and by using biomass expansion factor function, the regression equations of stand biomass and volume of the main forest forests in pearl river delta were built, and the regional forest biomass and its dynamics were estimated on the basis of forest inventory data

    摘要利用生物量轉換因子連續函數法，通過69組不同齡級的森林樣地實測數據，擬合了珠江三角洲主要森林類型的生物量和蓄積量之間的回歸方程，並結合3個時段森林清查資料，估算了區域森林生物量及其動態。
  4. 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。
  5. Some believe that couples who stand under the tower when the lights go on must vow eternal love. lovers can also tie a ribbon to a special christmas " love tree " on the tower ' s observation deck

    每逢聖誕來臨之際，日本著名的情侶約會地東京鐵塔的瞭望臺上將放置心形的照明物和一顆名為「愛情樹」的聖誕樹。
