Choosing d shifts & the largest eigenvalues of T m, we carry out d steps shifted QR factorization for T m, and initial vector v 1 is then updated. 取Tm的d个最大特征值为移位量,对Tm进行d步带原点位移的QR分解。然后,修改初始迭代向量v1。
The result shows that the initial rate V 0 of the esterification reaction increases as hexanoic acid concentration increases or as n-butanol concentration decreases, when the initial concentration of hexanoic acid is small; 结果表明,在正己酸的初始浓度C0HA较小时,反应初速率V0随正己酸浓度增大而增大,但随正丁醇表观浓度增大而减小;
According to the variation of organic solvent phase volumes after separation, three categories of two phase aqueous extraction have been observed : type ⅰ( V initial < V end ), type ⅱ( V initial > V end ) and type ⅲ( type ⅰ and concurrently type ⅱ). 根据分相后有机溶剂相的体积变化,双水相体系存在3种分相类型:型(V始V终)和型(兼具、型)
I throw it up with a certain v initial speed, v call it v0, I don't care and the horizontal component would never change. 我以一定的,初速度,向上扔-,称之为v0,无所谓-,水平分量不会改变。
In order to obtain an initial flying velocity ( v ) with good consistency, the effect of structural parameters of brush-shaped charge used in small-sized rocket motor on the value of vis studied. 为了得到稳定可靠的飞行初速,研究了某小型火箭发动机毛刷式装药结构参数对初速的影响。
