Conclusion the successful theoretical model provides theoretical foundation for the conducting heat properties of crystal material surface layer powerfully 结论理论模型比较成功,为晶体材料表面层中的导热问题提供了有力的理论依据。
So next work should be to study the crystallization mechanisnu nickel contents and mobility after the nickel - silicide on the surface is removed 对此方法的晶化机理和对镍的含量及去除表面层的镍化合物后迁移率的大小测试分析将在下一步工作中展开。
Normally sanitary napkin is consists of surface layer , absorbent layer and bottom layer , so you have to consider the materials and functions in the above three layers 卫生巾一般由表面层、吸收层和底层三部分构成,使用时就要从这三部分的材料及作用考虑。
These disc type semi - conductive capacitors are reformed smaller size with larger capacitance than usual hi - k type ceramic capacitors . the following is the comparative list for two kinds of semi - conductive capacitors 圆片型半导体电容器具有较高介电常数,电容器体积更小,电容量更大,有表面层和晶界层之分。
The experiment on the conclusion of shakedown analysis with the direct analysis method was conducted for proving residual stress of contact surface layer of the rolled specimen . the paper concerns itself on the following specific aspects : 1 本文针对接触表面层的强化与疲劳失效问题,提出通过研究接触表面层在循环载荷作用下的安定特性,来建立强化设计与疲劳评估准则。
After storage for a long time , a layer of li2co3 and absorbed species ( h2o , co2and o2 - ) will appear on the surface , and a thin nio - like layer will be formed on the near surface of linio2 material 长期贮存的linioz电极材料将在表面形成一层包含lizco3 、 hzo 、 co :以及残余活性氧物种02 .在内的覆盖层,以及在近表面层生成一层类似nio的立方岩盐结构钝化层,从而导致其电化学性能下降。
Oxygen atoms in the air are known to actively react with the fresh gaas . it was observed that the ga - o bond is stronger than that of as - o and that ga atoms preferentially migrate towards the surface leaving vacancies behind in the subsurface region . this behavior can convert the subsurface layer into an as - enriched one 本文分析了硫钝化后源漏饱和电流减小的原因,认为gaas表面极易被空气中的氧原子氧化,由于ga - o键比as - o键结合的更紧, ga原子优先向表面移动,这导致亚表面层成为富as层。
The pavement panel , under load and with already existing initial cracking & inherent damaged conditions as well as its cracks & damage , further accumulates and expanses , which lays a foundation for the fissures & breakage ; the surface layer - as the uneven pavement brings about interaction between spring plates which results in impact on the vehicle load , is the main reason speeding up the fissures in the pavement panel 在荷载作用下,使得已经存在初始裂纹和固有损伤条件的路面板,其裂缝和损伤进一步累积和拓展,为路面的断裂破坏奠定了基础;表面层? ?由于路面表面的不平整而引起的车板相互作用带来车辆运动荷载的冲击,是加速路面板断裂的主要原因。
The objective of this paper is to obtain metal - ceramic composite materials with better complex properties by the way of preparing nano - composite powders of metal and ceramic . in our thought , firstly we should prepare nano - ceramic powders coated with metal , and then during the period of sintering , the film of metal could prevent the nano ceramics powder from dumpling and keep the powders to be nano - sized 这样,在随后制备块材的烧结过程中,由于复合粉体复合充分,相容性提高,结合力高,另外金属表面层可抑制纳米陶瓷粉体的融合长大,使粉体在烧结后保持纳米尺寸,从而发挥纳米颗粒的作用;同时通过引入均匀分布的韧性金属相,进一步改善陶瓷的脆性。
