As the caprylic aldehyde content increased,train at break,tensile strength,crosslink density were decreased.

拉伸强度、断裂伸长率和交联密度基本上均随辛醛含量的增加而降低。

At each time point, we observed morphological changes, in situ detected DNA breaks, and observed expression changes of production of lEGs c-Fos and DNA repair enzyme APE/Ref-1 which participated in many kinds of DNA repairs. Results in the experiment were shown as follow:DHE stain indicates: The model of rat MCAO/R was credible, and the damaged regions included cortex (lobus frontalis, lobus arietalis, lobus occipitalis et al and caudatum.

本次实验采用大鼠大脑中动脉阻塞再灌注模型，将健康雄性SD大鼠随机分为正常组、假手术组和MCAO2h再灌注2h、6h、12h、24h、48h、72h组，观察各时间点损伤区域神经元和细胞的形态学变化，原位检测DNA断裂损伤，检测DNA修复酶APE/Ref-1表达变化情况以及IEGs产物c-Fos表达变化情况。

Proteases may be used at various pH values, and they may be highly specific in their choice of cleavable peptide links or quite non-specific.

蛋白酶需要在特定的pH中发挥效力并且对于断裂肽键具有或不具有特异性。

According to the geological features and the grade data of ore-forming elements,which are analysed systematically by using Yang Chizong filter method,in several deposits of Hu-Bi-type copper deposit,we propose that such orefield is controlled compositely by folds-thrust faults of NE direction and faults of NW direction,and that ore pillars are formed in the intersection area of structures mentioned above.

应用杨赤中滤波法系统分析了胡篦型铜矿几个矿床成矿元素的品位资料，结合矿床地质特征研究，认为该类矿床不仅受NE向褶皱冲断构造控制，而且还受NW向断裂构造复合控制，在其交汇部位形成矿柱。

The Jiashengpan lead-zinc-sulfur deposit, located in Langshan-Zhaertaishan mineralization belt in the western part of northern margin of North China Platform, rich in Mesoproterozoic Zhaertaishan Group, is obviously stratabound and controlled by synchronous fault. The ore bodies are mainly composed of layered, conglomeratic and disseminated ores.

甲生盘铅锌硫矿床位于华北陆块北缘西段狼山-渣尔泰山成矿带，赋存于中元古代渣尔泰山群地层中，具有明显的层控特征并受同生断裂影响，区内矿石层纹状、角砾状和浸染状构造发育。

The first impressions of the medical staff are that the cruciate ligament has been broken, but we hope that is not the case.

&队医的第一感觉是十字韧带已经断裂，但我们希望情况并非如此。&
