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。 -
The characters and the stability of volume of air quench steel slag have been summarized first in this paper. the air quench steel slag has good physical and chemistrial properties, and can be used to prepare concretes as aggregate. at the same time, theoretical analyzation and experiment results also show that f - cao content is very low, and mgo exists in the ro phase, so the volume of air quench steel slag is stabile
本文首先講述了風淬鋼渣的性質及其體積穩定性，指出風淬鋼渣具有良好的物理和化學性能，適合於作集料來配製混凝土；同時從理論上分析並通過試驗驗證表明，由於風淬鋼渣中游離cao含量很低，而mgo主要以ro相形式存在，不存在體積安定性不良的問題。 -
Life time of mn2 + in nano - zns was measured and was found to be close to that of the bulk materials. therefore the quenching centers quench the exciton but not the mn2 + ion self. 2. the increasing curves are different in film and ethanol colloids because there is diffusion process of quenching centers in colloids
對薄膜樣品的熒光增強曲線的擬合表明，顆粒表面猝滅中心數目隨輻照時間的衰減函數是非e指數形式;同時考慮溶液中猝滅中心通過向顆粒表面的擴散而逐漸耗盡，很好地解釋了溶膠的增強曲線與固體薄膜的增強曲線的不同。 -
Under legal agreements made during that time, the buendia dam is still obliged to relinquish enormous quantities of its precious water to quench the thirst of residents living in murcia in southern spain where the climate is even drier
按照當時的法律協議，布溫迪亞水壩要放出大量極為寶貴的水來解決生活在西班牙南部穆爾西亞的居民的缺水問題，因為那裡的氣候更乾旱。
