Tea polysaccharide can prolong activated partial thromboplastin time of human plasma significantly,but has no effects on prothrombin time and thrombin time.

茶叶多糖能明显延长人体血浆APTT值，而对PT、TT值的影响不显著，表明茶叶多糖主要通过影响内源性凝血系统而发挥抗凝血作用。

With these age referenced ranges, a physician in the specialty can also titrate the dose of human growth hormone to reach it optimal level in the patient ( that of a 20 year old healthy Chinese ).

从而我们可以判定这个被检查的病人是健康（胰岛素样生长因子-Ⅰ的水平处于正常范围）、不健康（胰岛素样生长因子-Ⅰ的水平低于其年龄所对应的参考范围），还是可能有肿瘤或疾病（胰岛素样生长因子-Ⅰ的水平值高于其年龄所对应的正常范围最大值）。

The db4 wavelet was applied in signal de-noising and the translation invariant wavelet was used to eliminate the Gibbs phenomenon .

对电力系统接地短路电流信号的去噪进行了研究，针对小波去噪等信号处理方法中存在的 Gibbs现象，提出并研究了采用db4小波进行信号去噪，采用平移不变小波变换，并以新型阈值代替传统阈值，进一步改善了去噪效果。

Metholds 236 patients were performed penetrating keratoplasty, in which laser trephination technique was applied. Patients were assigned to four groups:(0) K0D, regular mire;(1) K60, moderately irregular mire;(3) severe irregular, immeasurable mire based on the keratometry value and mires measured with semi-quantitative Ophthalmometer (Type-H, 190071 Zeiss, Jena, Germany).

回顾分析了236例圆锥角膜使用激光环钻技术进行的穿透性角膜移植手术手术，使用角膜曲率计(Ophthalmometer， Type-H， 190071 Zeiss， Jena， Germany)对手术前后的角膜规则程度进行检测，并结合所测出的角膜曲率值和角膜映光图像分成4组：(0)规则组，K0D；(1)轻度不规则组，K0；(2)中度不规则组，K≥60；(3)重度不规则组，K值不能读出，共4组。

But the data analysis is relied on experience and statistics in a certain extent, so sometimes it makes big errors. Daniudi gas field is a low permeable gas field, the pressure buildup slowly. The measured formation static pressure is low and the flow pressure is high, so the calculated unresisted flow is high.

特别是大牛地气田属于低渗透气藏，压力恢复缓慢，所测的地层静压值偏低，求产开井3天以上多数井测取不到稳定的流压，所取流压值偏高，计算的无阻流量均偏高。

Firstly, the integral-differential equation described the radiation field evolution is derived, and then the instability of its solution is also investigated analytically. By using the perturbation and iteration method, the threshold detuning and threshold linear growth rate of the unstable solution are analyzed and discussed in detail.

首先，建立了一个描述辐射场演化的积分一微分方程，解析分析了系统解的不稳定性，并采用线性方程解的微扰迭代方法进一步对系统不稳定解出现的失谐量阈值和线性增长率阈值等作了详细讨论。

RESULTS:The povidone-idione solution was more unstable in higher pH and temperature.When the temperature was 50℃ and the pH was 8,after 15 minutes the effective idine concentration dropped to zero.

结果：当pH值与温度越高，PVP-Ⅰ稀释液越不稳定，当温度为50℃，pH值为8时15min后有效碘浓度即下降为零。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
