SVD is the general method for linear decomposition of a matrix into independent principal components, and is a form of Eigenvalue-Eigenvector analysis or principal components decomposition and, in a more general sense, of multi-dimensional scaling.

SVD分解根据矩阵的运算计算出矩阵的奇异值，然后根据奇异值计算出矩阵的两个奇异矩阵，将矩阵分解为三个矩阵的乘积形式。

Westinghouse Prizewinner John Kuo recalls that in Taiwan he was accustomed to studying two or three hours a night."Here we had half an hour at the most."

According to certain ratios among the number of one, two or three bends in a chip, it computes the probability of usage of each unit line segment, thus resulting in a fast and accurate algorithm for congestion estimation.

依据芯片上含有一个、两个、三个拐弯布线的一定比例关系，计算出每条单位线段被使用的"概率"，进而产生了一种快速准确的拥塞估计算法。

We have three options, first past the post where the largest party wins all the seats in a state, and then two forms of proportional representation.

我们有三个选项，第一个过去的哨所，在那里赢得的最大的政党中的所有国家的席位，然后两种形式的比例代表制。

And obviously p,q/r is not valid according to the canons of propositional logic.

两个论证都必须简单地符号化为p，q/r，因为他们每一个都只包含有三个不同的非复合句子，并且很明显p，q/r的形式按照命题逻辑的原则不是有效的。

In this paper, phase equilibria of quinary reciprocal system K~+, Na~+//CO_~(2-), SO_4~(2-), B_4O_7~(2-)-H_2O and its subsystems (two ternary systems and three quaternary systems) at 273 K were studied by isothermal evaporation method .

采用等温蒸发法研究了五元体系K~+，Na~+／／CO_3~(2-)，SO_4~(2-)，B_4O+7~(2-)-H_2O及其中两个三元子体系、三个四元子体系273 K相平衡关系。
