The matrix extension problem is, under some constrained conditions, constructing a matrix A with a given matrix A_0 as its submatrix.

矩阵扩充问题是在某种约束条件下构造矩阵A，使得矩阵A的一个子矩阵为A_0.1979年，H。

In this note the author showed that if s is nonnegative integer and A∈B n,n+s, then |R|=2 n if and only if A contains a submatrix which is permutation equivalent to the unit matrix of order n.

作者证明：如果s是一个非负整数且A ∈Bn ，n+s，那么｜R ｜=2 n 当且仅当A含有置换等价于n阶单位矩阵的一个子阵

For example, the module name A.B designates a submodule named "B" in a package named "A".

例如，名为 A.B 的模块表示了名为"B"的包中名为"A"的子模块。

Methods CHD patients were proved by coronary arteriongraphy. 64 patients with type 2 diabetes in combination with CHD were enrolled in group A and 98 patients with simple CHD served as group B. Patients of group A were subdivided into 3 groups based on scalar of the stenotic coronary artery, viz 1 rarnus, 2 rami and 3 rami affection groups, and urinary albumin level was determined. In group A, age, course of DM, BMI, BP, BS, GHbA1c, blood-fat, UAL serving as iv, and affection sum and stenosis index serving as dv, ran polynary gradual regressive analysis.

随机选取经冠状动脉造影确诊的冠心病患者，其中2型糖尿病合并冠心病患者64例为A组，单纯冠心病患者98例为B组，比较两组患者的临床资料和冠状动脉病变情况。A组患者根据冠脉病变支数分为3个亚组，即l支、2支、3支病变组，比较亚组间的尿白蛋白水平；A组患者以年龄、体质量指数、糖尿病病程、血压、血糖、糖化血红蛋白、血脂、尿白蛋白为自变量，分别以病变数、冠脉狭窄指数为因变量进行多元逐步回归分析。

The extent of inhibition of depolarization by superfusion of ethanol for 5 minutes was 41.8±3.3 ％(n=17). The addition of 5 nM and 20 nM KT5720 (a selective protein kinase A inhibitor) and 250 μM H9 dihydrochloride (a non-selective protein kinase inhibitor), into the intracellular solution significantly attenuated the inhibitory effects of ethanol.

当分别将5 nM或20 nM KT5720（选择性蛋白质激酶A抑制剂）或250 μM H9 dihydrochoride（非选择性蛋白质激酶抑制剂）置入细胞内液时，乙醇的抑制作用明显被减弱；但乙醇的抑制作用不受到5 nM或20 nM calyculin A（磷酸酶1/2A抑制剂）的影响。

Ethanol inhibition was not affected by 5 nM and 20 nM calyculin A (a phosphatase 1/2A inhibitor). Prior superfusion of 5 nM and 20 nM KT5720 also attenuated ethanol inhibition of NMDA-mediated depolarization. 1 μM and 3 μM chelerythrine, a selective protein kinase C inhibitor or 20 nM calyculin A did not affect ethanol inhibition of NMDA-induced response.

当以表面灌流方式，事先给予5 nM或20 nM KT5720时，同样可以减少乙醇抑制NMDA引发的去极化作用；分别给予1 μM或3 μM chelerythrine或20 nM calyculin A则不会影响乙醇抑制NMDA所引发的反应。

Polymerase chain reaction amplification of a portion of a gene encoding a surface protein of Wolbachia was used to detect the Wolbachia infection of the population of Pteromalus puparum and Nasonia vitripennis by universal primers of wsp gene and the specific primers for wsp genes of A and B Wolbachia supergroup.

采用Wolbachia 的通用引物及A和B大组特异性引物对蝶蛹金小蜂Pteromalus puparum和丽蝇蛹集金小蜂Nasonia vitripennis体内Wolbachia的wsp基因进行PCR扩增及序列测定，并对测定的序列进行了同源性比较和基因特征分析。

Qing Jin - a site specific project by Dutch artist Peter Vink specially conceived for Platform China Contemporary Art Institute space A, is an installation which situated in the entrance hall of main space A. In this room the artist decides to show the audience the symmetric quality of this particular space.

请进》是荷兰艺术家彼得·温克专为站台中国A展厅量身打照的艺术项目，整个展览只有一件装置作品，这件作品被设定在A展厅的入口处，艺术家希望展现给观众这个特殊空间的对称特点。

In a symmetric relationship, the relationship of A to B is also true of B to A.

对称关系中，A至B的关系也是B至A。

8 A foul by either team:* Before the beginning of a period other than the first period, or * During the alternating possession throw-in, Does not cause the throw-in team to lose that alternating possession throw-in.

比如跳球后是B队拿到了球，第一节没有交替发生，那第二节本该A队发球。虽然A队在之间发生技术犯规，但是这个犯规不能使A队失去第二节开始的球权，仍然应该是B队2罚后由A队开球。
