查询词典 the positive

If a pool tests positive for HIV, the individual sample can be detected and removed for further processing, and the donor can be deferred and notified (Kaiser Daily HIV/AIDS Report, 8/19/04). Because NAT looks for the virus and not antibodies, health professionals are able to identify HIV-positive patients in the days immediately following infection -- when they are most contagious -- which could help slow the spread of virus.

Maculatus respectively(including CSP positive by ELISA and sporozoite positive in the salivary glands),and their entomological inoculation rate was estimated to be 9.82,3.97 and 2.69 respectively.

微小按蚊、中华按蚊、多斑按蚊子孢子阳性率(包括ELISA环子孢子蛋白阳性和镜检唾腺子孢子感染蚊)分别是0.37%、0.22%、0.32%，昆虫接种率分别估算为9.82、3.97、2.69。

The positive test draws the following conclusions: control rights is significantly negatively related with firm value which indicates that the bigger control rights the actual controller hold, the lower firm value is; cash flow rights is significantly negatively related with firm value which may due to the ravening share bonus deeds by controlling shareholder; the separation ratio of cash flow rights to control rights is negatively related with firm value and not significant which may due to the ravening share bonus deeds,or the deficient market, or inadequate information exposure etc; stock proportion restriction is significantly positive related with firm value which indicates the good effect of stock proportion restriction; actual controller who participate in the management and the ratio of director who have position in controlling shareholder's company don't pass the significant test; the size of the company is significantly negatively related with firm value; the ROE cannot explain the firm value.

通过实证检验发现，我国金字塔结构下民营上市公司的治理效应有以下特征：控制权与公司价值显著负相关，说明实际控制人掌握的控制权越大，公司价值越低；现金流权与公司价值显著负相关，这可能与我国民营上市公司控股股东的"掠夺性分红"行为有关；现金流权与控制权的分离率和公司价值负相关且未通过显著性检验，这可能与控股股东的"掠夺性分红"行为有关，也可能与市场的不完善、信息披露的不充分等有关；股权制衡度与公司价值显著正相关，说明我国民营上市公司的股权制衡机制能够产生一定程度的效果；实际控制人参与管理情况与在控股股东单位任职的董事比例和公司价值的关系均未通过显著性检验；公司规模与公司价值显著负相关；ROE对公司价值没有解释力。

In the long run, the cumulative effect of inequality on investment is negative.（2） Inequality has moderate effect on education, and the cumulative effect is positive.（3） The effect of inequality on investment overweighs its effect on education, so inequality has a strong indirect effect on growth instantaneously. The effect turns positive and then weakly negative.

研究发现：（1）收入差距在即期对投资有非常强的负面影响，之后影响变为正，再逐渐下降至微弱的负，从长期来看，收入差距对投资的累积影响始终为负；（2）收入差距对教育的影响较弱，其累积影响始终为正；（3）由于投资对于经济增长的作用超过了教育，因此收入差距对于经济增长的间接影响主要来自于投资的渠道。

And the sufficient and necessary conditions are obtained and the uniqueness of T is discussed and an algorithm for solving the inverse problem is provided. The other kind of structure inverse eigenvalue problem is for unitary Hessenberg matrices with positive subdiagonal elements. That is, a unitary Hessenberg matrices with positive sub-diagonal elements can be constructed when its eigenvalues and the eigenvalues of H_(11) and H_(22) are known. Here H_(11) and H_(22) are rank-one modifications of k × k leading principal submatrix of H and of its × remain submatrix respectively. In the end, the uniqueness of H and an algorithm is obtained.

文中首先讨论了这三组特征值之间的交错关系，接着确定了该逆问题有解的充要条件，并论证了其解的唯一性问题，最后给出了相应的数值算法；本文第二个问题解决的是一类不可约的酉Hessenberg阵的逆特征值问题：即一个不可约的酉Hessenberg阵可以由它的特征值、它的前k阶秩一修正的顺序主子阵的特征值以及它的后n—k阶余子阵的秩一修正阵的特征值来确定，文中最后讨论了唯一性和相应的算法。
