晶格異質 的英文怎麼說
中文拼音 [jīnggéyìzhí]
晶格異質
英文
lattice heterogeneity-
However, it is not easy to incorporate large n concentration in gap due to the large differences in lattice structure ( gan belongs to wurtzite structure while gap zinc blende structure ) and in lattice constant ( ~ 20 % ) between gan and gap, which will lead to an extremely large miscibility gap
然而要在gap中實現高濃度的摻氮並不容易。這主要是由於gap和gan之間較大的物理特性的差異,特別是晶格結構和晶格常數的差異,使得gap和gan存在較大的可混溶性間隙,從而難以生長高質量的高摻氮的gap材料。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。The effect of lattice mismatch on the nucleation process of heteroepitaxial growth of ultrathin film
晶格失配對異質外延超薄膜生長中成核特性的影響The theoretical calculation and explanation of strain behavior during heteroepitaxy of oxides thin films : when the lattice mismatch is relative small ( for example, batio _ 3 / srtio _ 3 with a lattice mismatch of 2. 18 % ), the growth mode of thin films is layer - by - layer, and the critical thickness and strain relaxation can be calculated or estimated by matthews - blakeslee expressions ; when the lattice mismatch is large ( for example mgo / srtio _ 3 with lattice mismatch of 8 % ), the strain relaxation process can be explained by theory of coherent strained islands
氧化物薄膜異質外延應變行為的理論預測和解釋。對于晶格失配較小的外延體系(如batio3 / srtio _ 3 2 . 18 % ) ,薄膜以層狀方式進行生長,臨界厚度和應變釋放過程可以用經典的matthews - blakeslee公式進行預測;對于晶格失配較大的體系(如mgo / srtio _ 3 8 % ) ,薄膜以島狀方式進行生長,應變釋放過程可以由彈性應變島的理論體系進行解釋。The heteroepitaxial growth of 3c - sic on si substrate not only unfurls the maturity of si process, but also incarnates the excellence of 3c - sic, so that it become for long researchful direction. due to the large lattice parameter mismatch ( ~ 20 % ) and the large thermal expansion coefficient mismatch ( ~ 8 % ), however, the 3c - sic / si study is very difficult
然而,由於3c - sic與si之間存在較大的晶格失配度(約20 % )和熱膨脹系數差異(約8 % ) ,因此, 3c - sic / si異質外延薄膜的制備非常困難,仍存在許多技術問題需要克服。As a kind of condensed state matter, the characteristic and structure of liquid crystal between solid crystal and isotropic liquid. it is a ordering liquid, as the macroscopical characters are concerned, it have the flowing power and viscidity like liquid, and the anisotropy like crystal, it has birefringence, bragg reflection, diffraction and optical rotation like crystal. furthermore, it has thermal light effect, electrical light effect or magneto optical effect in outside field
它是一種有序性的液體,從宏觀物理性質上看,既具有液體的流動性、粘滯性,又具有晶體的各向異性,能象晶體一樣發生雙折射、布拉格反射、衍射及旋光效應,也能在外場作用下產生熱光、電光或磁光效應。We, fafa gems, has more than ten years experimence to develop and produce zirconium, spinel, corundum, etc. we always hold the attitute of trying best to inovate and making our product in the highest quality to run business. now, we are able to offer many kinds of zirconium and jewel end product. those zirconiums have many kinds of colours and shapes. all of the products we offer are in high quality and worthwhile to trust. and the prices are reasonable
