As one of aliphatic polyether-ester, poly (p-dioxanone) shows not only excellent biodegradability, biocompatibility and bio-absorbability, but also good flexility, tensile strength and knot strength. The PPDO has already been used in some biomedical materials such as suture, bone repair device and may have potential application in peroral or parenteral drug delivery systems.

聚对二氧环己酮是脂肪族聚醚酯的一种，不仅具有优良的生物降解性、生物相容性和生物可吸收性，而且具有出色的柔韧性、抗拉强度和结节强度，可应用于生物医用材料，例如手术缝合线、骨科修复材料等，并在口腔和非肠道给药系统中具有潜在的应用前景。

A series of novel polyethylene glycol derivates was synthesized by esterification of chloroacetic acid with polyethylene glycol. Because of the good reactive activity of α-chlorin in the esters it can react with 5-fluorouracil, thus the conjugate can be obtained .

采用氯乙酸与不同分子量的聚乙二醇进行酯化反应得到氯乙酸聚乙二醇酯，由于酯中的α-氯具有良好的反应活性，将它再与抗癌药物5-氟尿嘧啶结合制备了不同分子量的高分子前药。

By measuring solvent evaporation rate, ratio of drug PLA precipitates,drug distribution in system and entrapping ratio at different time of preparation, we found the difference of precipitation velocity of drug was the main reason.

沉淀法制备载药聚乳酸纳米粒，即使同是脂溶性药物，但因药物与丙酮之间相互作用及药物与PLA之间亲和力的不同，包载效果仍可能出现较大差异，选用时应慎重。

After particle distribution analysis and test of penetration of oil perforation to steel target,the influence of particles arrangement and distribution of powder shaped charge liner on performance of jet was studied and the liner was treated by thermal treatment.

利用筛分法，将127型石油射孔弹药型罩中的铜粉进行颗粒分级，并与其他金属粉进行粒度级配，通过粒度分布分析及射孔弹侵彻钢靶试验，研究了粉末药型罩中金属颗粒的粒度级配及分布对聚能射流性能的影响，同时对药型罩进行了热处理研究。

One chamber near the epidermis was filled with OCAs, and the other one was filled with isotonic saline. The dynamic changes in transmittance and the skin thickness were monitored after the application of six saturated alcohols to in vitro skin samples. From the observed results at 60 minutes, the optical clearing effects of six OCAs, i.e., glycerol, polyethylene glycol 400 (PEG400), polyethylene glycol 200 (PEG200), 1, 3-propylene glycol, 1, 4-butanediol and 1-butanol, showed in the descending order.

针对离体皮肤，建立模拟在体环境的给药方法(皮肤表面给药、真皮面与等渗生理盐水作用)，考察6种饱和醇类试剂作用后皮肤厚度及透射光强的变化。60分钟的动态观测发现，各试剂均能产生不同程度的光透明作用，皮肤光透明效果由强到弱依次为：甘油、聚乙二醇400(PEG400)、聚乙二醇200(PEG200)、丙二醇、丁二醇、正丁醇。

In this paper, two kinds of material model were introduced, based on the same condition, such as explosive, liner structure, Johnson-Cook and Steinberg model were selected for liner. The process of shaped charge jet penetration into target was simulated using ANSYS/LS-DYNA, the results compared and showed that these two kinds of model can simulate the form and penetration process of the jet accurately, and the top velocity of the jet head were almost the same.

本文介绍了两种材料模型，在炸药、药型罩结构等条件相同的情况下，药型罩选择Johnson-Cook与Steinberg两种材料模型，利用ANSYS/LS-DYNA软件对聚能射流侵彻靶板进行模拟仿真，对比仿真结果，得出两种模型都能很好的模拟射流的形成及侵彻过程，且各时刻射流头部最高速度差值很小。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
