摘 要：对不使用任何化学引发剂在真空下使壳聚糖与L-乳酸接枝共聚进行研究，结合真空冷冻干燥工艺制备一种用于周围神经再生的复合不对称膜材料。

The screening test also reveals that tin chloride dihydrate/p-toluenesulfonic acid system is particularly effective for increasing the molecular weight of PLA.

而SnCl〓·2H〓O+TSA二元催化体系能够很好地催化乳酸缩聚反应，并且可以抑制外消旋和变色等副反应的发生。

This process usually takes millions of years, givingthe oil and gas deposits time to migrate around the globe on the back of plate movements.

同时，在这样充满乳酸的环境下。利用葡萄糖在无氧下分解来生成能量的代谢途径，也缺乏效率。

Methods: Twenty-four male SD rats were randomly divided into normal control (NC, n=6), protein C activator (PCA, n=6), lipopolysaccharide (LPS, n=6) and LPS+PCA group (n=6). NC group were given normal saline and PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. LPS group were administered lipopolysaccharide (10 mg/kg, 4h) by intraperitoneal injection method to make the model of septic shock rats. After the animal model was made, LPS+PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. 30 minutes after the injection, each rat was tested by Medlab biosignal analyzing system for observing mean arterial pressure and left ventricle function, the activity of LDH and iNOS in myocardium and the cuttings of myocardial tissues.

取SD雄性大鼠24只随机分成对照组、PCA组、LPS组和LPS+PCA组四组，对照组尾静脉注射生理盐水，PCA组尾静脉注射蝮蛇毒蛋白C激活物，LPS组腹腔注射LPS (10 mg/kg， 4h)的方法建立败血症休克的实验动物模型，在建立败血症的实验动物模型的基础上，尾静脉注射PCA (0.4 mg/kg)为LPS+PCA组，每只大鼠均于药后30 min时运用Medlab生物信号采集处理系统记录平均动脉压和左心室功能指标，并测定心肌中乳酸脱氢酶活性、诱导性一氧化氮合酶活性及心肌病理切片。

Methods 22 patients undergoing elective surgery were divided into two groups randomly:group HVH and group IVH.After induction of anesthesia, blood was withdrawn via radialis artery while Ringer's lactate solution with threefold the volume of blood withdrawnor Dextran 40 with the same volume as blood withdrawnwas infused in big peripheral vena with identical speed.

选择22例外科择期手术病例，分为HVH和IVH两组，于全麻稳定后，经桡动脉采血，同时外周大静脉匀速输入3倍于采血量的乳酸钠林格液或等于采血量的右旋糖酐施行血液稀释。

I have to give them up Jin Gu Bang L-calcium lactate, I feel that good results, but prices are also cheaper.

我一直给他们补金箍棒L-乳酸钙，我觉得效果不错，而且价格也便宜。

Results: The mechanical properties of the PDLLA mini-plates and screws appeared to be sufficient to enable undisturbed healing of depressed zygomatic arch fracture.

结果：对颧弓凹陷性骨折，分子量高达60万kD以上的超高分子量聚D，L乳酸小夹板螺钉的机械性能足够维持骨段的稳定性并支撑其愈合。

Which energy in is produced, without oxygen, through the breakdown of muscle glycogen into lactic acid and admen troposphere, the energy provider 整个作定语从句,修饰说明 process.

无氧糖酵解就是将能量供应者——肌肉肝糖在无氧的情况下分解成乳酸和 ATP，并制造能量的过程。

The extracting technology included calcium salt method and high vacuum distillation method, etc.

最后对南京绿天源生物化工工程有限公司的乳酸炼制工艺的流程和技术特点进行了简要介绍。

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.

本文分别采用不外加碳源和维生素B〓外加碳源（包括乳酸钠、丙酸钠或乙酸钠）、外加维生素B〓以及同时外加碳源和维生素B〓的方法，考察了p，p'-DDT、γ-HCH和HCB三种氯代有机污染物单独或混合存在下，在辽河沉积物中缺氧脱氯降解的情况，主要得到以下结论

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
