D-Pantothenyl alcohol, also called ortho-vitamin 85, is an important nutrition suppled substance. It has been widely applied in the field such as medicine, cosmetic, foodstuff, feed additive, and so on. The preparation of D-pantothenyl alcohol and the optimization of key factor are discussed mainly in this paper. It mainly includes three section.In the first section, with formaldehyde, isobutyl aldehyde and diethyl oxalate as the starting materials, D-pantolactone is prepared via three steps including condensation, catalytic hydrogenation and physical resolution. The specific rotatory power of the product is consistent with imported product.

D-泛醇，俗称原维生素B_5，属维生素B旋类营养增补剂，广泛应用于医药、化妆品、食品、饲料等领域，本文着重探讨了其制备及关键因素的优化，主要内容可分三部分：第一是D-泛内酯的制备，先以甲醛、异丁醛和草酸二乙酯为起始原料合成酮基泛内酯，再经催化氢化得到DL-泛内酯，然后通过物理拆分获得D-泛内酯，得到产物的比旋光度与进口产品基本一致。

Well-suited for applications such as reinforced slopes, basal reinforcement, temporary walls for staged construction and surcharging, and for modular block faced walls, extensible reinforcements are used primarily in commercial and residential applications where the possible elongation of the reinforcement and resulting lateral deformation can be tolerated.

Although CdS and NiSe belonged to the same crystal system, they had a great difference in the morphology of products produced in ethylenediamine by a solvothermal process. By making a crytallographic comparison between CdS and NiSe, I thought that fourcoordinated crystals were more prone to grow one-dimensionally in the stacking direction of tetrahedrons. This hypothesis could also be embodied in many examples.

硫化镉和硒化镍的晶体结构都为六方晶系，但在以乙二胺为溶剂的溶剂热条件下合成出的产物形貌有很大的差别，我们通过对两类晶体结构的结晶学比较，我们认为4配位的晶体更趋向于生成一维纳米材料，并提出生长方向即为四面体堆积方向，这一假设也能得到许多例子的证实。

电镜观察发现，Cd(上标 2+)处理下，细胞核变形，核仁解体，染色质凝集；类囊体片层膨胀，叶绿体双层膜破裂；线粒体中嵴突减少或消失，线粒体空泡化。

In the aspect of writing angle , their works are personal and fashional ; In the aspect of writing means , their works use a narrative means of body behavior ; In the aspect of beauty-appreciation , their works has the tendency of vulgarizing while becoming estranged from and revolting against tradition .
