By analyzing the sample, study the method of seeking given parameters by using Lengendre polynomials and condition of fixedsolution.
通过实例分析，探讨用勒让德多项式和定解条件求解静电场时确定系数的方法。

Many mathematical models in the fields of physics, chemistry, biology and geology can be boiled down to the fixedsolution problem of linear or nonlinear partial differential equations (PDE.)
物理、化学、生物、地质等领域的很多模型都可归结为线性或非线性偏微分方程的定解问题。

Most agree that the solution is to push doctors to accept fixed payments to care for a particular illness or for a patient's needs over a year.
