刺激层体现神经元的连接，知识层体现专家的规则、推理，从而将专家系统的符号计算和神经网络的连接主义两者有机的结合，并在其基础上构建了形体的表征模型、推理方法，实现了形态构成知识的产生，为人脑模型的“智能”能力的实现和应用奠定了基础。 - By using the solutions of a new auxiliary elliptic equation , a direct algebraic method is proposed to construct the exact solutions of some nonlinear evolution equations . the main difference between this method and previous auxiliary elliptic equation methods is that the balance order becomes smaller after using the new auxiliary elliptic equation . therefore , the derived algebraic equations are greatly simplified . meanwhile , the obtained new solutions contain more parameters to be chosen . for some special cases , they give the previous known solutions . it is shown that some new exact periodic solutions of some nonlinear evolution equations are explicitly obtained with the aid of symbolic computation
利用一个新的辅助椭圆方程将求解非线性发展方程精确解的问题转化为一个代数方程组进行求解,与已有的辅助椭圆方程法的主要不同是,应用这一新的辅助椭圆方程后降低了平衡次数,减少了所得的代数方程组的个数和方程的项数,从而大大地简化了代数方程组的求解.同时,由于辅助椭圆方程的解中包含了更多的可选参数,从而给出了非线性发展方程的更多形式的解.作为应用,借助于计算机的符号计算,求得了一些非线性发展方程的新的精确周期解 - With the development of the computer and the constantly expanding of it ' s applied domain , symbol computation present gradually powerful bioenergy . in this paper , using the computer algebra as the tool and the differential algebra as the background , we discuss the theory of " ac = bd " and the differential characteristic method and their application in the differential equations
