查询词典 positive

Studying the positive definitiveness of the covariance matrix from discrete data is important to design the sampling plan and provides the base for the data analysis.However, there have been few outcomes about the positive definitiveness of covariance matrix, most of which have been restricted to the Covariance-matrix of continuous sample.

研究离散型样本协方差矩阵的正定性有助于判断是否可以降低样本的维数，有利于优化抽样个数，为抽样调查的优化设计方案提供一定的理论基础；为基于特征根的多元统计分析提供理论指导。

I stained it for PAS with diastase pretreatment, and saw NO CYTOPLASMIC PAS-POSITIVE CRYSTALS (the photos of PAS-positive crystals shown above were taken from the vertebral tumor resected later).

我经淀粉酶消化后染 PAS ，没有看到胞浆内的 PAS 阳性结晶(PAS阳性的图象是椎骨肿物后染的阳性)。

Immunohistochemical studies were performed in 6 cases. Cytokeratin 7 was diffusely positive in all cases studied, whereas cytokeratin 20 and cytokeratin 17 were focally positive in 4 and 2 cases, respectively.

我们给6例做了免疫组化，细胞角蛋白7全呈弥漫的阳性，细胞角蛋白20和细胞角蛋白17分别在4例和2例中呈局灶阳性。

In recent years, medical science progresses, the Gram-positive bacilli have a more in-depth study. Here on Gram-positive bacilli in the mononuclear cells of Listeria monocytogenes, Diphtheroid bacilli, erythema silk erysipelas bacteria of Clostridium perfringens and Clostridium difficile, Bacillus anthracis and Nocardia infections, Detection and treatment are reviewed.

近年来，医学科学不断进步，对革兰阳性杆菌有了更深入的研究，为此就革兰阳性杆菌中的单核细胞增生性李斯特菌、红斑丹毒丝菌、产气荚膜梭菌、艰难梭菌，炭疽杆菌以及诺卡氏菌的感染、检测方法及治疗作一综述。

Results 1. For the normal group,20.2%(101/500) specimens were detected positive forHPV infection. 1512 women were included in the abnormal group and 523(34.6%)specimens were detected positive for HPV DNA, including 407(77.8%) one-typeinfection, 82(15.7%) diplex infection and 34(6.5%) multiple infection.

收集宫颈癌组织标本，针对HPV16亚型分别设计L1、E6和E7基因特异性引物，用PCR方法从宫颈癌组织中获得各基因的全长序列，并构建克隆载体pMD18-T，进行序列分析，同时分别以L1、E6和E7基因序列进行进化分析。

In this thesis, we consider positive solutions of a degenerate parabolic system with homogeneous Dirichlet boundary condition. It is proved that all positive solutions exist globally iff 12≥abλ, whereλ1 is the first eigenvalue of ??

该论文研究一类具有齐次Dirichlet边界条件的退化抛物方程组正解的性质，证明了所有正解整体存在的充要条件是12≥abλ，其中λ1是具有齐次Dirichlet边界条件的？？

When there are diffusion effects and Dirichlet boundary conditions, we firstly obtain the conditions such that the system exists positive equilibrium solutions and give the asymptotic expression of these positive equilibrium solutions.

在具有扩散影响和Dirichlet边界条件时，首先利用隐含数定理获得了系统存在正平衡解的条件和正平衡解的渐近表达式。

While these gradients could all be detected reasonably well,we found a slight shift in discriminability in favour of positive gradients and found that surfaces with no gradient at all were more likely to be judged to have a positive gradient.

让被试辨别表面质地密度变化的方向，结果发现被试能够很好地判别表面质地密度变化的方向，但在判别正向变化的表面时显得更准确；当表面密度没有变化时，被试倾向于判别为正向变化。

Kant also helped to prepare the way for the total disparagement of human reason in relation to religious truth, which constitutes the negative side of Traditionalism, while the appeal of that system on the positive side to the common consent and tradition of mankind as the chief or sole criterion of truth and more especially of religious truth -- its authority as a criterion being traced ultimately to a positive Divine revelation -- is, like Kant's refuge in practical reason, merely an illogical attempt to escape from Agnosticism.

康德也有助於编写方式，为总贬低人类理性与宗教的真理，它构成了一个负面的传统，而提出上诉，该系统在积极方面，以共同同意和传统，为人类的作为行政或检验真理的唯一标准，更尤其是对宗教的真理-它的权威作为标准，并追查，最终以积极的神圣启示-是，像康德的庇护所，在实际的理由，只是一个不合逻辑的，企图逃避追捕，从不可知论。

The downstroke produces a positive upward force and forward thrust; the upstroke produces a positive upward force and rearward thrust.

该downstroke产生了积极向上的力量和前瞻性的推力； upstroke产生了积极向上的力量和靠后的主旨。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
