The results were as follows:(1) The method that HA was treated by ethanol of 2.5x volume for 20 hours turned out to be the most economic and efficient.(2) Zymolysis combined with deproteinization by chloroform was better than deproteinization by chloroform for several times in yield and purity of HA.(3) HA with purity of 71.1 60/o was obtained by the fermentation with cetylpyridinium chloride.

本文对发酵液中HA的分离提取方法进行对比研究，结果表明采用2.5倍体积的乙醇对HA沉淀，作用时间20小时最为经济合理；采用酶解结合氯仿除蛋白较之氯仿除蛋白，HA的产量和纯度均有所提高；经氯代十六烷基吡啶分级分离后，可得纯度为71.16％的HA产品。

With the guide of non-linear program theory, by using interpolative steps and inexact line search, an improved conjugate gradient method was found, by which the training rate of BP networks increases by tens or hundreds of times. Moreover, the improved method is effective to solve non-linear equations for which Newton's method does not converge owing to the problems of the quadratic derivative and inverse matrix.

通过大量的数值模拟试验发现，在非线性规划理论的指导下采用间插步骤和不精确的一维搜索技术改进的共轭梯度法，是基于梯度和共轭方向的连续搜索算法中最有效的算法，这种算法使BP网络的训练速度提高几十到几百倍，使BP网络的实际应用效果大为改善；而且这种算法对于用牛顿法由于求二阶导数和求逆矩阵等问题难于收敛的非线性方程组的求解也是很有效的。
