进一步地，我们采用二分法与相平面分析结合的方法计算压差方程的数值解。

Furthermore, we compute the Riemann solution by using a bisection method combined with the phase-plane analysis.

采用二分步法，从积分型方程出发，在有限控制体上建立守恒型差分格式，对二维浅水波方程进行求解。

By use of the time split method, a conservation difference formula is established to find the solution to the shallow water equation based on the finite volume control method from integral equations.

二分式结果以相对风险性报告，连续标度的测量结果以95%可信区间均值标准差报告。

Dichotomous outcomes are reported as relative risk (RR) and measurements on continuous scales are reported as mean differences (WMD) with 95% confidence intervals (CI).
