The mountain materials, Russia expected, the Qinghai-hat "tremolite" small crystals have a certain arrangement of different materials, such as Qinghai, the crystal fibers are arranged mostly in the same direction, showing a translucent and strong, and this has not been a natural Sorting mountain materials, micro-fractured, micro-cracks will affect the diffuse light glossy surface, it is generally not a good oil lubrication performance sense, but there are also individual mountain material, because structure is very good, so oil is also very good, used to play, and Tian's friends must have taken note of this in!

而山料、俄料、青海料"透闪石"小晶体的排列方式有一定的不同，如青海料的晶体纤维的排列多为同一方向，表现出透光性强，并且这种没有经过自然分选的山料，微裂隙发育，微裂隙对光漫反射会影响表面的光泽感，所以一般表现不出很好的油润感，但也有个别的山料，由于结构非常好，所以油性也非常好，经常玩和田玉的朋友一定也注意到这一点了！

Four non-ionic europium complexes,〓-phen(11),〓·bipy(12),〓·dia(13) and 〓(14)(TTA=2-thenoyltrifluoroacetone, DBM=dibenzoylmethane, phen=phenanthroline, bipy=2,2'-bipyridine, dia=4,5- diazafluoren-9-one, dmbp=4,4'-dimethyl-2,2,-bipyridine), were synthesised and the triboluminescent phenomena of 12, 13 and 14 were firstly observed. Structure determinations of 11,12 and 14 were carried out. The triboluminescence maxima of 12 and 13 are similar to those of their photoluminescence. X-Ray structure analyses show that Eu atoms all exhibit eight-coordinate tetragonal antiprismatic geometries and complexes 11, 12 and 14 are all centrosymmetric.

二、合成了四个非离子型的铕的配合物：〓、〓、和〓(14)[HTTA=2-噻吩三氟甲酰丙酮，DBM=二苯甲酰基甲烷，phen=邻菲罗啉， bipy=2，2'-联吡啶，dia=4，5-二氮杂芴-9-酮，dmbp=4，4'-二甲基-2，2'-联吡啶]，首次报道了12、13及14的摩擦发光性质，测定了11、12及14的晶体结构，并系统地讨论了晶体结构和摩擦发光活性之间的关系。12及13的摩擦发光光谱的极大值均类似与其相应的光致发光光谱，表明它们有相同的激发态。

Caprolactam grafted carbon fibre could improve the initial crystallization temperature and the crystallization rate more obviously than ungrafted carbon fibre. The crystallization of nylon 6 was determined by nucleation. The nonisothermal crystallization dynamics was well coincident with the rule of both of Jeziorny and Liu equation. isothermal crystallization dynamics fitted to Avrami equation.

用广角X射线衍射法对晶型结构进行研究，表明碳纤维使原生态的样品中α晶型的含量降低，结晶度下降，其中接枝聚己内酰胺链段的碳纤维／MC尼龙6原位复合材料中α晶型的含量比未接枝的碳纤维／Me尼龙6原位复合材料的多，结晶度也较大：样品淬火时，碳纤维有利于基体尼龙6结晶时形成γ型晶体，接枝聚己内酰胺链段的碳纤维更有利于基体尼龙6结晶时形成γ型晶体；淬火后的样品在200℃下退火2个小时后γ晶型完全转变为α晶型。
