In chapter three, we divide the rows of matrix into types finer than those in chapter one. Again by looking for positive diagonal matrix factors, we obtain several new criteria for identifying generalized strictly diagonally dominant matrix, improving some existing criteria.

第三章在下标集N 递进式划分的条件下，根据递进后，某些下标集上部分矩阵元素的性质，寻求正对角矩阵因子，获得了广义严格对角占优矩阵的几个新判别法，同时改进了一些已有结果。

When the soldering temperature and soldering heat-retaining period is identical, the diffusibility of Cu in the rapid-solidifying solder is remarkably higher than that of the ordinary solder.

同时，在相同的钎焊条件下，快冷钎料Cu元素的扩散能力均比普通钎料的扩散能力强。

A liquid amine ashless antioxidant HAO without phosphorus and zinc was prepared by alkylation of diphenylamine and 12 carbon iso olefin mixture, which can be applied at high temperature.

以二苯胺和含C12 的混合异构烯烃为原料，通过烷基化工艺，研制出了适于高温条件下应用的不含磷、锌元素的液态胺型无灰抗氧剂双十二烷基二苯胺。

This paper proposes a hybrid scheme, which combines the advantages of spectrum LU decomposition and direct solution.

文中采用谱分解方法建立起矩阵列元素的谱分解表，并采用直解法的递推公式，可以快速给出矩阵的分解。

The parallel sorting by divide point locating algorithm is proposed and analyzed in this paper.

这一类算法的效率和可扩展性，在很大程度上取决于确定划分元素的开销及划分后数据分布的平衡程度。

When first character is double quotation marks, this element's type is array of char.

当首位的字符为双引号时，可以判定这个元素的类型是 char 的数组。

The dblclick event usually fires when the pointing device button is double clicked over an element.

可以通过在某个绑定的函数中返回false来防止触发浏览器的默认行为。dblclick事件会在元素的同一点双击时触发。
