The whole process is completed within 200 s. The 91Sr product is radioactively pure, with an overall recovery better than 90%. The decontamination factor is greater than 10^2 for 92Sr, and better than 10^3 for other radionuclides. The quality of 91Sr specimens thus prepared can meet the requirements for its decay data measurements.

用辐照235U的裂变产物溶液进行了全流程验证，得到的91Sr溶液为放化纯，Sr的化学回收率大于90%，对92Sr的去污因子大于10^2，对其它主要核素的去污因子大于10^3，结果满足衰变数据测量的要求。

Using a neural network algorithm to establish a typhoon rainfall model and to seek the nonlinear relations between the relevant parameters and rainfall intensity is a rational approach. The rainfall data used in this study include rain gauge data and radar data, and is able to reflect the spatial distribution of the precipitation pattern.

雷达具有空间侦测能力，利用地面雨量计的雨量资料与雷达回波的资料，可以将空间中的降雨分布趋势表示出来；本研究当中所决定的台风降雨因子是根据过去相关研究文献所整理出来，而这些台风降雨因子是否能完全模拟台风降雨的机制，尚待观察。

The correspondence relationship between the parameter of a point on a rational Bézier curve and its weights is given, and (n-1) factors of shape-unchanged are obtained.

Clinical characteristics and outcomes were recorded. Risk factors for ICU readmission and risk factors of mortality were evaluated.

同时，也进一步辨别重返加护病房病患的危险因子及重返病患中死亡的相关因子。

The authors investigated the environmental-geological conditions of a certain refuse landfill site in Beijing and the ability of strata to prevent refuse pollution and monitored groundwater pollution by refuse for one consecutive hydrologic year.

通过对北京某垃圾场所处的环境地质条件、地层对垃圾污染物的防护能力的调查及对地下水连续1个水文年的污染监测，用单因子和多因子(综合污染指数和内梅罗污染指数)2种方法，评价了该垃圾场对地下水的污染情况。

Methods We randomly assigned young boys with severe hemophilia A to regular infusions of recombinant factor VIII or to an enhanced episodic infusion schedule of at least three doses totaling a minimum of 80 IU of factor VIII per kilogram of body weight at the time of a joint hemorrhage.

研究人员将65名30个月龄以上的重度A型血友病男孩随机分为两组，32名患儿规律注射重组VIII因子25IU/Kg，隔日一次，另外33名则在关节出血时注射重组VIII因子至少3个剂量，总量最少要达到80IU/Kg。

AFGF shows greatpotential for clinical applications for therapy of a variety of diseases, such as Parkinson'sdisease, spinal cord contusion injury, neural regeneration in reimplantation of broken-offfinger, brain ischemia, renal ischemia, myocardial infarction, occlusive vascularitis, retinalischemia, gastric ulcer and nonhealing wound and so on. We expressed human acid fibroblast growth factor gene transiently in tobacco byAgro-bacterium mediated vacuum infiltration and studied the factors, which influenced theexpression level.

人类酸性成纤维细胞生长因子(aFGF，FGF-1)是成纤维细胞生长因子超家族成员，来自于三个胚层的多种细胞都可以表达aFGF.aFGF在治疗帕金森综合症、急性脊柱扭曲性损伤、断指中神经功能重建、脑缺血、肾缺血、心肌梗塞、闭塞性脉管炎、视网膜缺血、胃溃疡及难愈合性伤口等多种临床应用方面具有巨大潜力。

But there were no statistical differences in these factors between AGEs group and control ones after RAGE were interrupted by siRNA.Conclusion In this study model,the phenomena of increased cell cycle relative factors and inhibited cell proliferation might be one of the endogenous compensating mechanisms in keratinocytes treated with AGEs.This mechanism was correlated with RAGE signal pathway.

在上述体外模型下，表皮角质形成细胞的周期调控因子升高，而增殖却下降且凋亡增加，可能是AGEs干预后细胞内启动内源性代偿调控机制，且这种调控机制与其受体途径相关；AGEs也可能还通过以上细胞周期调控因子以外的其他途径或机制影响细胞生物学功能。

Temperature is also a main factor affecting the summer runoff, and the relative influences of mean minimum temperature and averaged diurnal temperature range are 34%, 31%, respectively.

春季径流量的增加归因于平均最低气温的升高，其影响程度为68%；温度同样是影响夏季径流的主要因子，平均最低气温，平均日较差相对影响程度分别为34%、31%；降水量增多、平均地温升高是秋季径流量增加的主要原因，相对影响程度分别是35%、65%；影响冬季径流的主要气候因子是冬季平均最低气温、平均地温，影响程度分别是36%，64%。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
