  1. Based on the analyses on mechanical properties, microstructure and fracture of - the microalloyed steels socrv with various heat treatment technique, it can be affirmed that various fractures arttribute to various mechanism, we can draw conclusion that the strength and toughness of microalloyed steels 50crv will be increase simultaneously by optimal heat treatment technique. to illustrate the mechanism of the strength and toughness of microalloyed steels socrv, we designed the comparative experiment and observed the microstructure of the sample which occurred at different quench and tempering temperature and different tempering time. the last experiment results were determined by the four factors : fined microalloyed elements grains, the decompound of martensite, martensite transformation of remnant austenite and the second phase precipitation

    為解釋微合金化50crv鋼強韌化機理，本文通過對不同淬火溫度，回火溫度，回火時間下的力學性能指標的對比及顯微分析，認為微合金元素的細化晶粒，馬氏體的回火分解，殘余奧氏體的轉變，第二相的沉澱析出共同決定了微合金鋼的強韌化情況，特別是由於微合金元素的存在，其細化晶粒及其碳氮化物的沉澱析出，導致鋼的良好的強韌性，並且如果工藝滿足第二相的沉澱析出強化大於回火馬氏體分解引起的軟化效應，會在硬度曲線中產生明顯的二次硬化現象。
  2. In the positioning servo - system, which generally is configured by the d. c. pulse width modulator ( pwm ) velocity governing system and position servo - loop, the parameter perturbance of pwm velocity loop really exist by reason of such as the load behavior ; power voltage supply ; operating setting value, etc. 1, 2 ， and it cannot be ignored. by using the identification technique to form the mathematical model of the system, authors have confirmed the facts. therefore, to design the discrete sliding mode controller ( dsmc ) of the positioning servo - system, the perturbed parameters value bounds of the pwm velocity loop, which is as the controlled plant of position servo - loop, should be accounted. consequently, the design principle of dsmc for accounting system with parameter perturbance is proposed by the authors. the proposed method can ensure the stability of system with parameter perturbance and the behavior of non - overshoot, fast precise positioning. in order to reveal the effects of the design method, the comparative research work is done by the authors. also, it has been tested in an industrial experiment, the results proved it is satisfactory
