脆變溫度 的英文怎麼說
中文拼音 [cuìbiànwēndù]
脆變溫度
英文
embrittlement temperature-
High accuracy kdp crystal optics is now considered as one of optics that is the most difficult to be processed for its series of disadvantageous characteristics to optics processing such as anisotropy, soft nature, easy to deliquesce, high brittleness, sensitive to temperature change, easy to crack and so on. therefore the long machining period, low percent of pass and astaticism quality has become the bottleneck of icf technology, and the surface quality control of kdp crystal processing has become the key problem to be solved in the research of icf in our country
Kdp晶體零件是目前公認的最難加工的光學零件之一,因為kdp晶體具有各向異性、質軟、易潮解、脆性高、對溫度變化敏感和易開裂等不利於光學加工的特點,所以加工周期長、合格率低、質量不穩定成為慣性約束聚變技術的瓶頸, kdp晶體超精密加工表面質量控制問題已經成為我國慣性約束聚變研究中亟待解決的關鍵問題。It seems the ncz silicon has a higher bdt temperature compared with cz silicon ' s. it is suggested that the elastic effects and the electronic effects of nitrogen doped in silicon made the bdt temperature higher. the observation of fracture surface showed that it was curves at high temperature in brittle fracture, but smooth planes at room temperature
當溫度升高達到硅材料的脆塑轉變時,材料的斷裂強度有個很大的提高,但是首次發現含氮硅單晶卻不明顯,而且摻氮的硅單晶脆塑轉變溫度比普通單晶高,可能是氮的摻入改變了硅材料的內部晶體結構及電子結構。Wearing while it s true that gemstones such as ruby and sapphire are second only to diamond on the hardness scale, it is not a measurement of their indestructibility
鉆石的物理特性較穩定,可用沸水清洗,但一些寶石如綠寶石紫水晶均非常脆弱,易受溫度劇變的影響,應盡量避免使用沸水。The knowledge on the properties of used materials is urgently needed for reasonable life - prediction and life - distribution. as cylinder bolts are concerned, they often rapture at the first tooth - root resulting from lower high temperature strength of their material and higher stress. since bolts operate at high temperature environment, creep skew and damage causing their failure are important factors that can not been neglected
就汽缸螺栓而言,由於螺栓材料的高溫強度偏低,預緊力過大,常常在螺栓的第一齒根部位發生蠕變脆性斷裂,因其長期在高溫環境下工作,蠕變變形和蠕變損傷是其失效的一個不可忽略的重要因素。The mathmatical interrelated models for transition temperatureof ductile brittleness fracture for mild steel
高氮鎮靜鋼韌脆轉變與溫度的關聯數模Brittle - ductile transition temperature
延脆轉變溫度( 3 ) both oxide - induced closure and embrittlement of grain boundaries take place for 2 - cr1mo and 2 - cr1mov at high temperature. the change of fatigue crack growth rates with temperature is not so evident as 316land 16mnr
裂紋表面氧化引進的閉合效應和晶界脆化相對比較均衡,裂紋擴展速率隨著溫度升高的變化沒有鐵素體和奧氏體材料明顯。Conventional mos image sensors require polymer onchip microlenses and dyed rgb color filters, which are fragile and extremely susceptible to sunlight exposure and a change in temperature
傳統的mos圖像傳感器需要採用聚合在電路板上的微透鏡和染色rgb顏色過濾器,這種脆性材料非常易碎,而且在日曬下和溫度變化時極其易受影響。分享友人
