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 .

方法：采用计算机图像处理技术，对378例正常人体颈椎中间位侧位片弦、弧长度进行测量，通过二元一次方程求解计算出正常颈椎生理曲度。

Methods : The length of cervical spinal curving strings and arcs were measured on middle potential lateral radiographs in 378 normal persons cervical spines by computer imaging processing system , and the physiological curvature were figured out through solution of dualistic once equation .

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 .

针对三维流函数和其方程特性，将两个流函数方程的差分方程视为同时求解两个流函数的二元一次联立方程，采用相应数值计算方法。

Based on the analysis of the stream functions and their principal equations , to overcome the difficulties the discretized equations of these equations are adopted as the simultaneous difference equations of solving two stream functions .

最后应用它来解某些二元一次不定方程和计算平方根的近似值。

In the end it is applied to some linear indeterminate equation with two changeable unknowns and calculation of approximation of square root .
