查询词典 the positive

The variation of positive selective pressures from initial positive selection to eventual purifying selection not only represents the adaptive evolution of S protein from animals to human, but also provides a good clue to investigate the interspecies transmission of other viruses.

从最初的阳性选择到最后的负选择，S蛋白经历了变化的自然选择压力。这种变化的选择压力不仅反映了SARS-CoV由动物向人类跨种传播的适应性进化过程，也为研究其他病毒的跨种传播机制提供重要线索。

Positive outcomes can be a difficult sell when juxtaposed with tax cuts,pothole repairs,airport security,and defense spending,But there is good reason to believe that attention to positive outcomes has the additional effect of educing negative outcomes.

积极的成果可以是一个困难的时候出售并列减税，坑洞维修，机场安全，国防开支，但有理由相信，注意积极成果有更多的负面影响引出的搜索outcomes。

As to the principle of abstraction, the positive analysis is merely concerned about a positive and neutral interpretation of its function, and not about value judgment; however, with purpose of enhancing its persuasion in the level of value, the teleology demonstrates further the legitimation of that principle, through emphasizing its function of protecting safety of transaction.

功能实证分析只是对无因性原则的机能进行一种实证的、中立的描述，与价值判断无涉；目的论是从无因性原则中发现的交易安全之保护机能来进一步论证该原则的正当性，以增强其价值层面的说服力。

The research instruments included " Science Concept Comprehension Test, Science-related Attitudes Scale, and Problem Solving Ability Test". The results of this study were that: STS group had significantly positive effect than traditional group on SCCT, SRAS and PSAT.(2) Field-independent students had significantly positive effect than Field-dependent on SCCT.(3) There were no interaction between teaching methods and cognitive styles.

刊究结果发现在问题解决能力、科学理解与科学相关态度三方面，STS组学生皆较一般组学生有正向的表现，且前测并不影响学童在此三方面的后测表现；在认知风格上，场地独立性的学童在科学概念理解上表现较场地依赖性者正向，但不同认知风格学童在科学相关态度和问题解决能力两方面并没有显著差异；学生的认知风格和教学法之间，在科学概念理解、科学相关态度和问题解决能力三方面皆无交互作用产生。

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.

结果 采用神经管植块法培养的神经嵴干细胞，免疫细胞化学染色呈现nestin及P75双阳性，将其接种在壳聚糖纤维支架材料上，可见神经嵴干细胞贴附于壳聚糖纤维上生长；S-100免疫细胞化学染色显示，S-100阳性细胞突起的末端呈扁平状膨大；扫描电镜显示，壳聚糖纤维上的躯干神经嵴干细胞为梭形，呈现"端对端"、"肩并肩"排列，伸出爪形伪足贴附于壳聚糖纤维上。

Results The testing results showed that this method with 100% specificity and sensitivity in 300 positive and 100 negative samples of mammalian sera respectively. However, the positive serum samples of Francisella tularensis, yersinia pseudotuberculosis and yersinia enterocolitis could not be deceted by dipstick of ICA.

结果 间接血凝法检测阳性300份血清标本，胶体金法检测全部为阳性，间接血凝法检测阴性100份血清标本，胶体金法检测全部为阴性，两种方法符合率100％；并且鼠疫胶体金法快速诊断盒不与假结核耶尔森氏菌等相关细菌的免疫血清发生交叉反应。

How to make positive self-evaluations which is a condition sine qua non for the positive evaluation of the child.

The main problem with the radix -1 complement is that a negative or a positive zero exists; in the radix complement system, only a positive zero can exist.

反码的主要问题是它存在负零或者正零，而补码系统中只能存在正零。

Methods Sera derived from 226 SLE cases and 183 healthy controls were tested for ANA and all parameters were compared such as sensi- tivity,specificity,accuracy,positive predictive value,negative predictive value,positive likelihood ratio,nega- tive likelihood ratio,result consistency,rank correlation coefficient and kappa of ANA detected by IFA...

方法同时采用IFA法和ELISA法检测血清ANA共409例，其中SLE 226例和健康对照183名，将两种方法检测结果的敏感度、特异度、准确度、阳性预测值、阴性预测值、阳性似然比、阴性似然比、结果符合率、判断一致性κ值及秩相关系数进行比较分析；通过ROC曲线比较两种方法的准确度；结果不一致标本进行可提取性核抗原抗体谱检测分析；同时将IFA法检测不同荧光模型样本分别与ELISA结果进行相关分析。

Results 176 cases were positive,positive rate was 80%.

结果 阳性176例，阳性率80％。
