孿晶界 的英文怎麼說
中文拼音 [jīngjiè]
孿晶界
英文
twin boundaries-
Two area defects are twins and grain boundaries.
有兩種面積缺陷,即孿生和晶粒間界。The macroscopic defects such as twins, small - cracking, scattering particles, growth layer and cores are examined ; they are related with the temperature difference between gas and melt : the twins and small - cracking come out when the difference is large, the bubbles and scattering particles come out when that is small
觀察到了孿晶、裂隙、雲層、生長層和核心等宏觀缺陷,晶體的這些宏觀缺陷與氣- -液界面溫差有較大關系:溫差大容易造成孿晶、裂隙等缺陷;溫差小容易造成氣泡、散射顆粒等缺陷。The dfz might fragment and rotate as crack propagation
裂尖前方可能發生形變孿晶,裂紋沿孿晶界擴展。Coherent twin boundary
相干孿晶間界Defects such as extended dislocations, pile - ups of dislocation and grain boundaries ( twin boundaries ) were also investigated
塗層中存在擴展位錯、位錯塞積列、 (孿)晶界等晶體缺陷。Further ncrease in c content leads to lattice contraction, due to the solid solution in ubstitution mode, i. e. replacing si in the p structure
的b軸和c軸又幾乎相等,這都容易形成孿晶,使得界面情況變得復雜。Recently bulk tb - dy - fe single crystals have been obtained by magnetic levitation cold crucible without contamination in wuhan university of technology. these excellent single crystals, possessing a large displacement output under low magnetic field, build a foundation for the fabrication of the high precision micro - displacement actuators. the purpose of this research is to manufacture an advanced micro - displacement actuator with this high performance single crystal as the driving unit
常規的磁致伸縮型微位移致動器大多採用多晶或具有孿晶結構的磁致伸縮材料作為驅動單元,由於晶界和孿晶界對疇壁的移動具有阻礙作用,其低場下的位移輸出較小,調控精度受到很大影響。分享友人
