一元一次方程

学生学习离不开方程，求一元一次方程和一元二次方程的根十分必要。

The students need equation , It is very necessary that slover the root equation of a degree and equation of two degree .

从前求一元一次方程和一元二次方程的根，要求输入方程的系数，数据间逗号或空格分隔，输出方程的根。

Once upon , slover the root equation of a degree and equation of two degree that need input coefficient of equation , data separate need comma or space , output the root equation .

由于该法对安全系数K是直接求解一个一元一次方程而得到，故计算精度也高于其它各法所得结果的精度。

Since safety K is obtained by solving directly a linear equation according to the method , the calculation precision is also higher than using other methods .

采用回归分析法，得出描述丙烯腈中过氧化物含量与聚丙烯腈纤维黄度之间关系的一元一次线性回归方程。

The linear regression equation on the relationship between peroxide content in acrylonitrile and PAN fiber yellowness was obtained by regression analysis .

而采用等效能量法后，可以将这个积分方程组转化为一个二元一次线性方程组来进行求解，从而提高了计算的速度和准确度。

While the equivalent energy way will simplify the group into a new group of two linear equations and it increases the computing speed and accurancy .

然后给出每一小段用初参数表示的解，再利用各段之间的连续条件，给出内力与位移的一般表达式，并最后将问题归结为一个二元一次方程组的求解。

By use of the continuous conditions between adjoining sections , ge - neral formulas of internal forces and displacements are derived and the prob - lem finally becomes to solve a simultaneous linear equations with two unk - nowns .
