乘积表示的英文
英文翻译product representation&&&&product&&&&0&&&&infinite product representation&&&&cartographic represenation of area&&&&tensor product representation&&&&product representation of equation&&&&square integrable representation&&&&log&&&&[数学] product&&&& volume table&&&& a cumulative table&&&&area table&&&&loading table&&&&lc product&&&&product&&&&product method&&&&work product&&&&sum of products&&&&mad&&&&product moment&&&&product code&&&&product area&&&&product group&&&&product graph&&&&product term
例句与用法The volume v is given in terms of the scalar triple product .体积V能用数量三乘积表示。The volume v is given in terms of the scalar triple product体积v能用数量三乘积表示。 A simple and practicable solution to function - product derivative two equations with one unknown on matrix of product一种使用矩阵乘积表示一元函数两项乘积求导公式的简易方法Using the hankel transform , the state vector equations are reduced to a set of ordinary differential equations . according to the theory of ordinary differential equations and the cayley - hamilton theorem , an analytical solution of the problem is presented in the form of the product of initial state vector and transfer matrix , which is given for the four distinct eigenvalues each . applications of the solutions are discussed利用hankel变换,将状态变量方程转化为一组常微分方程组;进而根据常微分方程组解的理论和cayley - hamilton定理,得到了以状态变量和传递矩阵乘积表示的单层压电压磁弹性材料的解析解;并讨论了4种不同特征根的情况以及解的应用。 Gin is the abbreviation for grouting intensity number . it is showed by the product of the final grouting pressure p ( unit : mpa ) on the grouting section and the grouting volume v ( unit : l / m ) on every one meter of the grouting section , which means the energy consumed on every one meter of grouting section . according to gin method , if during the grouting construction , same energy is consumed on every grouting section , i . e . gin keeps to be a constant , an approximately uniform impervious curtain can be obtainedGin ( groutingintensitynumber )即灌浆强度值,它用灌浆孔段上最终的灌浆压力p ( mpa )和单位灌浆段长度浆液灌注量v ( l / m )的乘积表示,其含义为单位灌浆段上消耗的能量, gin法灌浆认为在灌浆施工中,保持各灌浆孔段上消耗一致的能量,即保持gin为常数,便可形成一道大致均匀的防渗帷幕。 &&

两个向量乘积的平方等于这两个向量平方的乘积吗?怎么用两个向量和其模表示向量夹角正弦值?

在解析几何里并没有"两个向量乘积",只有两个向量的内积(又称点积)和外积(叉积),中学里只学了内积.向量a●向量b=│a││b│cos〈ab夹角〉由上面内积的定义可知:一般情况下,两个向量内积的平方并不等于这两个向量平方的内积.由此,还知道用两个向量的内积和其模可表示向量夹角的余弦值,再由正弦和余弦的关系就能求出向量夹角的正弦值了.
