  2. Its nonsense ; childs play ! he went up to the map, and began talking rapidly, pointing with his wrinkled finger about the map, and proving that no sort of contingency could affect the adaptability of the drissa camp to every emergency, that every chance had been foreseen, and that if the enemy actually did make a circuit round it, then the enemy would infallibly be annihilated

    胡說， kinderspiel 。 」他走近地圖，用肌肉萎縮的指頭點著地圖，開始快速地講起來，他證明任何意外的情況都不能改變德里薩陣地的適當性，一切都預見到了，假如敵人真要迂迴，那就一定會被消滅。
  3. Firstly, this paper introduces the asynchronous motor model, and compares it with the dc motor ’ s. then the paper studies the principle of vector control, and proposes an improved current model of rotor flux observer. this paper also studies the three - level inverter ’ s topology, working principle, the neutral - potential unbalance mechanism and its controlling strategy. the paper especially studies the svpwm in details. the interface between the vector control and the three - level inverter is studied in details, including the generation of reference voltage vector, its judging of the sector and triangular regions, and the working mechanism after it sent into three - level inverter. when synthesizing the reference voltage vector, select the vector which only includes p and o states as the starting vector, thus eliminate the vector shift problem when sector changes. this paper fully takes advantages of the powerful functions of matlab / simulink to set up the simulation model. this construction is very explicit. the simulation results verify the inverter voltage output is correct, the rotor flux is steady, the asynchronous motor ’ s dynamic and steady state performances and speed modulation are excellent

    本文首先介紹了異步電機的數學模型，在此基礎上將異步電機的數學模型與直流電機的數學模型進行了比較;然後介紹了矢量控制的基本原理，採用了一種改進的轉子磁鏈電流型觀測模型;對三電平逆變器的電路拓撲、工作原理、中點電位不平衡的機理及控制方法進行了介紹，詳細分析了空間矢量脈寬調制策略。本文對異步電機的矢量控制與三電平逆變器之間的介面進行了詳細的研究，包括:參考電壓矢量的形成、所落扇區與具體小三角形區域的判斷、送入逆變器之後的工作機理。在參考電壓矢量的合成時，選擇只包含p 、 o狀態的空間電壓矢量作為起始矢量，解決了扇區切換時的矢量突變問題。
  4. At the same time, vp4 gene was mutated in a certain point by pcr. the plant expression vector : pbi121 was constructed and then transformed to agrobacteriutn tumefaciens eha105 directly. a. tumefaciens eha105 harboring pbi121 / vp4 was used to transform the boechmeria nivea l. guad according to the leaf disc procedure
