By using three broad distribution standards of polytitanocarbosilane whose number average molecular weights are determined by VPO, the calibration equation of gel permeation chromatography of the preceramic polymer polytitanocarbosilane which generally haslow average molecular weight and high branching degree was established as follows: ln M=

采用以气相渗透法测定了数均分子量的宽分布含钛聚碳硅烷作标样，通过计算机辅助建立了具有较低分子量和较高支化度的陶瓷先驱体聚合物——含钛聚碳硅烷的凝胶渗透色谱校准方程lnM＝20.9－0.843T。

From the outside to the inside , the body skin is divided into the stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm and stratum basale , after through stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm EGF can reach the stratum basale: accelerate the basal cells prpliferation and differentiation , reverse matured cells' differentiation to make stem cells that will form a " stem cells island " with a certain amount , which accelerate the generation of new cellls , make senescent cells keratinize and shed rapidly , make broken and denatured collagen fibers and elastic fibers repaired , so the skin's elasticity increase , and the wrinkles calm down or disappera gradually .

体表皮由外及里共分为角质层、透明层、颗粒层、棘细胞层、基底层，EGF可以通过透明层、颗粒层、棘细胞层深入肌肤基底层，加速基底层细胞增殖分化，将已经分化成熟的细胞逆分化成干细胞，当达到一定量时，便会形成&干细胞岛&，加速新细胞的生成，让衰老细胞快速角化、脱落，已断裂、变性的胶原纤维和弹性纤维得到修复，皮肤弹性增加，皱纹逐渐平复、消失。

A model of reactive astrogliosis was successfully established in vitro which showed an active reaction to injury. The characteristics of reactive gliosis parallel that seen in vivo.

体外分离培养的Ast对损伤表现出活跃的反应，呈现出典型的反应性胶质化特征，其发生、发展过程与规律类似于在体情况下的Ast反应。

Due to the key challenge for complicated techniques and preparation, there were few reports about ternary systems. A series of polyimide/SiO_2-TiO_2 hybrid films with different contents of inorganic particle were fabricated using tetraethoxyl silicane and tetrabutyl titanate as precursor in situ with sol-gel method and both phases in situ. Chemical structure and micro-morphology of hybrid films were studied by means of IR, SEM and XRD.

本文以正硅酸乙酯和钛酸四丁酯为前驱体，采用原位溶胶-凝胶法和两相原位同步法制备了一系列不同含量的聚酰亚胺/SiO_2-TiO_2杂化薄膜，利用红外光谱、扫描电镜和XRD观察了薄膜的化学结构和微观结构，并测试了薄膜的热稳定性、电击穿场强和耐电晕性。

The infected tissues were changed at the cellular level in morphological structure and physiological and biochemical metabolism, such as cell wall collapse, tylose plugging in air cavities, reduction of glairin and amylum, cell lignification, and brown gum in vessels. The crude toxin produced by F.

受侵染的植物组织在细胞水平上发生一系列形态结构和生理生化代谢的病理变化，包括细胞壁消解、侵填体堵塞气腔、粘胶质减少、淀粉量减少、细胞木质化和黄褐色胶状物堵塞导管等。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
