Through experiments analysis, it is found that the integrated lts is the most versatile laser tracker available for dimensioning, tool building, alignment, and reverse engineering applications with the characteristic of high tracking precision and excellent dynamic capability. this paper also provided an effective new method and technique in the application of large workpieces and industry field measurement and orientation by using dual - frequency laser interferometer
實驗結果表西安理工大學碩士學位論文明這套跟蹤測量系統能夠適用於高精度、響應速度快和動態性能要求高的工業現場安裝與測量，具有廣泛的應用前景，同時也為雙頻激光干涉儀在大工件和現場測量、定位的應用提供了一種有效的方法與技術，並為三維空間的跟蹤測量方法的研究奠定基礎。 -
The main reason are as following : on one hand, the nd - rich phases in the hydrogen desorpted powders is so brittle that they are easily milled too fine and some are run off seriously, and then inducing low density. on the other hand, the alignment of the magnets prepared by hydrogen desorption are much low. so the hydrogen desorption process should be modified, and the solution methods can be the substitution of traditional ingots with strip cast, the enhancement of the alignment magnetic field and the addition of nd - rich phase or ( and ) lubricant before the press
主要原因是hd磁粉中的富釹相較脆，在球磨時容易被磨成超細粉而造成過量流失和使磁體燒結不夠緻密；另外一個原因是hd法燒結磁體的易磁化軸的取向度較低，為了提高hd磁體的b _ r和（ bh ） _ （ max ）可對hd工藝進行改進，改進的方法可以是用鑄片代替鑄錠，提高成型磁場強度以及在磁粉成型前加富釹相和潤滑劑。
