With the increase of amylum quantity, the color of each the standard solution iodine combined with amylum changes dark and the its absorbance enlarges, the linear part in standard curve enlarges, while the amylum quantity are 20 ml and 50 ml respectively, the length of linear part in standard curve is not changed, so the optimum quantity of amylum is 20 ml.

对于碘标准系列溶液，随着显色剂淀粉用量的增加，溶液的颜色加深，吸光度在增大，标准曲线的线性部分加长，加入淀粉为20 ml和50 ml时，直线部分的长度变化不大，因此，加入20 ml最为理想。

In order to control the flow separation by reducing the diffusion factor and enlarging the diameter of inner circle, the meridian plane profile of the return channel was redesigned, which is achieved by substituting arbitrary curve for the circle with no change of the axial length of the stage. Bezier curve with eight parameters was chose to describe the shape of meridian plane profile, and the optimization of the meridian plane profile was implemented combining back-propagation neural network with genetic algorithm.

改进的主要思路是减小弯道前半部分通道的扩压度，并同时加大弯道出口内侧的转弯半径，主要做法是在不增加整级轴向尺寸的前提下，用任意曲线取代传统弯道的同心圆环结构，给定弯道回流器子午型线的外侧型线，采用Bezier曲线对内侧型线的2段曲线进行参数化描述，利用遗传算法和反向传播(back-propagation，BP)神经网络相结合的方法对内侧型线进行优化，得到新的弯道回流器子午型线。
