The resulting semi - solid mixture then flows homogeneously , figure 1 , behaving as a thixotropic fluid with viscosity depending on fraction solid , morphology , shear rate and time 这样最终形成的半固态混合物会均匀地流动（图表1 ） ，并依据固体粒度、晶形、剪切速率及时间而形成粘性触变液体。
The x - ray diffraction analysis shows films prepared by rf and ve have scattering peaks , however the peak intensity of pure cdte films prepared by css method is higher than ahead both 而且用css方法制备的cdte薄膜晶粒度大，薄膜晶形好。利用近距离升华技术在glass / ito基片上先后沉积cds 、 cdte膜，保证cds膜的厚度< 2000
Xrd and dsc were used to investigate the surface treatment and the content of the nano - sio2 influencing their crystalline characteristic . results showed that pp / nano - sio2 had the same crystal type with pure pp . so the melt point changed a little 通过dsc及xrd对复合材料的结晶特性进行研究：纳米sio _ 2粒子改性的复合材料的晶形为晶形，与纯pp相同，熔点并无明显变化；纳米sio _ 2具有成核剂的作用。
The tourmaline is a kind of boron and silicate mineral , calling " the green imperial or royal seal " of the gems , there are its colors in many , the crystallization has nothing in common with each other , the crystal structure has tripartite crystal , six arrises body , post form body and one bunch of needles form fibrous respectively , the hardness of the tourmaline is generally about 7 . 3 - 9 . 6 , the relative density is 3 . 03 - 3 . 25 式中r代表金属阳离子，当r为mg2 fe2或li al3时，分别构成镁电气石黑电气石和锂电气石三个端员矿物种。电气石晶体呈近三角形的柱状，两端晶形不同，柱面具纵纹，常呈柱状针状放射状和块状集合体。
This edta route has several remarkable advantages in comparison with other method . because of the greater ability of edta anions to chelate metal cations , and forming very stable and soluble complexes , all of the starting materials are mixed at the molecular or atoms level in a solution , it is easy to control the composition and a high degree of homogeneity is achievable 传统的合成方法是高温固相反应，由于灼烧温度高、灼烧时间长，形成硬团聚体，产物粒径较大，一般为m级，需进行球磨粉碎以减少其粒径，很难制得均相、均一粒度分布的氧化物粉体，在研磨过程中容易引入杂质且晶形破坏使得发光亮度减小。
The experimental results show that the cycle of the mother liquid increases the yield of the product , the seed crystal can improve long - diameter ratio remarkably , the proper additive reduces the speed of crystal growth and make size distribution homogenize . through appending different seed crystal and bivalent lead at one time , we may receive when the content of the seed crystal is 0 . 075 % and pb2 + is 20 - 50ppm , the yield of the basic magnesium chloride whisker is high and crystal shape is good . the surface active agent can improve dispersion performance of the basic magnesium chloride whisker 研究结果表明：母液循环可以提高碱式氯化镁晶须的产率；添加晶种可明显的改善晶形；合适的添加剂可以降低晶体生长速度并可提高晶须的粒径分布；而同时加入不同用量的晶种和pb ~ ( 2 + ) ，试验结果表明晶种含量在0 . 075 ， pb ~ ( 2 + )在20 50ppm时，晶须的产率高，晶形好；表面活性剂对产品的分散性能有所改进。
Components , structure and surface morphology of the resulted films were identified by fourier transform infrared ( ftir ) spectroscopy , x - ray diffraction ( xrd ) and scanning electronic microscopy ( sem ) . the analyses showed the content of cubic boron nitride in the resultant films on substrates was rather high and crystal particles of c - bn with uniform size , smooth crystal plane and regular shapes ( quadrangle and hexagon ) densely arrayed on the substrate 傅里叶转换红外吸收( ftir )光谱仪、 x射线衍射( xrd )仪和扫描电镜( stm )的测量结果显示，基底上的bn膜中立方相含量很高，且晶粒大小均匀、排列致密，晶形呈规则的四角和六角形。
