Materials and Methods: Forty Sprague-Dawley rats were randomly divided into normal group, control operative group and operative group which includes 6 subgroups (1,3,7,14,21,28 days). The spinal cord hemisection injury model was made by cutting the posterior right side spinal cord. Function changes in the right posterior limb were evaluated by BBB method. The general morphology changes were observed by HE stain.

材料与方法：40只成年SD大鼠随机分为正常组，假手术组和手术组，手术组又分成1，3，7，14，21，28天组，选取制作脊髓右侧半横断损伤模型，BBB法进行右下肢功能评分，HE染色观察损伤脊髓不同时段的大体形态学变化，原位杂交法观察slit-2 mRNA的表达变化，计算阳性细胞灰度值，进行统计学分析。

Methods The amount of δ-hemolysin from different strains and growth phases is analyzed by high performance liquid chromatography and the curve of the amount of δ-hemolysin vs growth time was drawn.

采用高效液相色谱法检测不同菌株、不同时段的右溶血素的分泌量，绘制其与生长时间、细菌生长量的关系曲线。

The timing very well planned and as you say the planning involved with hijacking four planes simultaneously...

时间计划的很好，就如你所说的计划同时段劫持四架飞机

In almost all of the disputes that have been resolved, however, particularly on arid or exotic streams, the paradigms used for negotiations have not been 'rights-based' at all — neither on relative hydrography nor specifically on chronology of use — but rather 'needs-based.

在几乎所有的被解决的水争端中，尤其是那些干旱地区或异常河流的情况中，谈判的范式根本不是"权利本位"——既不是水文学的也不是关于河流时段利用方面的——而是"需要本位"。

Based on the eco- environment function, confirmed the constitution of eco- environment water demand(including the inside of the watercourse.and the ecological water demand of the outside of the watercourse such as ecological water demand of economical crop, of lake or reservoir and of cities.).③Analyzing the physical geography, hydrography, economy characteristic and water resource status, getting the proper calculation method. The Tennant applied to the eco- environment water demand of inside of the watercourse, woodland minmum eco- environment water demand calculation method applied to the eco- environment water demand of woodland, water ration method applied to farmland the eco- environment water demand, water evaporation method applied to the reservoir eco- environment water demand.

本文以流域生态环境需水为主要研究对象，因此重点阐述了流域生态环境需水量的分类和计算方法；②通过分析流域生态系统构成与流域生态环境功能，并分时段和河段考虑，确定了桃花江流域生态环境需水量的组成，即包括维持现状河道生态环境功能现状的现状生态环境需水量与流域生态环境改善的生态环境需水量，前者包括河道内生态环境需水量(维持河道基本生态功能需水量、维持河道自净稀释功能需水量、补充地下水水量及美化流域景观娱乐需水)与河道外生态环境需水量(流域内植被、森林、农田的需水量和与河道相连的池塘、水库等的需水量)；后者还包括为治理改善流域生态环境而拟规划林业生态建设所需水量；③对桃花江流域的自然地理、水文地质和社会经济特征以及水资源现状及其主要生态环境问题进行了综合分析，提出了适合桃花江流域的生态环境需水量计算方法，即采用Tennant法计算河道内生态环境需水量，采用林地最小生态环境需水量法计算林地生态环境需水量，采用需水定额法计算农田生态环境需水量，采用水面蒸发法计算水库、池塘生态环境需水量。

MethodsThe same dosage of hypoxanthine, different uricase inhibitor are used singly or combined to replicate hyperuricemia model, inspect the uric acid in serum at different periods of time.

方法采用相同剂量次黄嘌呤，不同剂量尿酸酶抑制剂单次和连续给予复制代谢性高尿酸血症模型，测定造模后不同时段大鼠血尿酸值。

Beijing Liujian Construction Corporation, Beijing 100039,China;3.China Academy of Building Research,Beijing 100013,China The compound organic thermal insulating material used in outer-wall external thermal insulation has become the importable fire source.

本文在对外保温火灾发生的阶段和原因进行简要分析的基础上，对近期典型的火灾案例按火灾发生不同时段进行分类选编，所有案例均涉及外墙保温所用的有机保温材料。

The incipience of elite news is approximately between 1852, when Marx wrote for the New York Tribune, and 1917, when the Pulitzer Prize for Journalism is set up.

以"新闻界的一般状况"为基点，以"新闻佳作"为新闻精品之"元形态"标本，进行历时性考察得知，"新闻精品"之发轫期可大致锁定于马克思为《纽约论坛报》撰稿之1852年至"普利策新闻奖"设立之1917年时段。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
