1. As to doubly fed adjustment system , it will own excellent dynamic and static behavior if vector control is used . but if the system includes speed and position sensor , it will cause the increment of cost , descend of reliability , complication of structure and limitation of application area
   雙饋調(diào)速系統(tǒng)，如果采用矢量控制，將具有良好的動、靜態(tài)性能，但若系統(tǒng)中設(shè)有位置傳感器和速度傳感器，則會使系統(tǒng)的成本增加、可靠性降低、結(jié)構(gòu)復(fù)雜、從而使應(yīng)用場合受到很大的限制。
2. The contributions done are as follows : according to the mathematical model of doubly fed motor and the theory of vector control , a unit power factor of rotor control scheme is proposed . in the doubly fed adjustment system , in order to control magnetic torque of motor this scheme is designed by controlling the reverse direction between rotor voltage and current to keep the vertical direction between rotor current and flux . it is known from theoretical analysis that for partly decoupling this scheme is only effective under sub - synchronization speed , but not control the system and obtain steady state since speed adjustment system ca n ' t adjust the magnitude of rotor flux under sup - synchronization
   而傳統(tǒng)的無速度傳感器雙饋調(diào)速矢量控制系統(tǒng)，由于采用磁鏈定向方法，在同步速附近存在較大的工作死區(qū)，針對上述問題，本文做了如下的研究工作：本文從雙饋電機(jī)的數(shù)學(xué)模型出發(fā)，根據(jù)矢量控制的基本原理，提出了一種轉(zhuǎn)子側(cè)功率因數(shù)為1的雙饋電機(jī)矢量控制方案的設(shè)想，即在雙饋調(diào)速時采用轉(zhuǎn)子電流定向的方法，并控制外加轉(zhuǎn)子電壓與轉(zhuǎn)子電流始終反相，以保持了轉(zhuǎn)子電流與轉(zhuǎn)子磁鏈?zhǔn)噶看怪?，通過控制轉(zhuǎn)子電流的大小來達(dá)到控制電機(jī)電磁轉(zhuǎn)矩的要求。
3. The path - way controlling of neptunium in co - decontamination step of purex process , the extraction thermodynamics of amido podand and its usage in recovery of actinides from simulated hllw have been investigated . more than 95 % np were maintained in np ( v ) in 1a extractor and flowed into 1 aw , if enough amount of hno2 was added in feed adjustment and then hno2 scavenger ( urea ) was added before extraction . three kinds of amido podand were synthesized , and the extraction of lanthanides , actinides and some fission products were studied . one of them ( tbopda , n , n , n ' , n " - tetrabutyl - 3 - oxa - pantenadiamide ) was used as extractant to recover actinides from hllw . the results of experiments show that more than 99 . 99 % actinides were recovered from hllw and separated basically in groups . the main digests are as follows : 1
   镎走向控制研究中通過調(diào)價階段加入亞硝酸、而萃取前清除亞硝酸的獨(dú)特辦法可以將大于95的镎趕入1aw 。合成了三種酰胺莢醚萃取劑，研究了它們對錒系和裂片元素的萃取熱力學(xué)，通過條件實(shí)驗(yàn)選擇了其中一種莢醚tbopda ( n ， n ， n ’ ， n ’ ?四丁基? 3 ?氧戊二酰胺) ，進(jìn)行了從模擬高放廢液中分離錒鑭系元素的工藝研究，錒系的回收率大于99 . 99 ，并且基本上實(shí)現(xiàn)了錒鑭元素的組分離。其要點(diǎn)如下： 1
