First low order approximation of generating function and approximate optimal trajectory were obtained. Then using low order approximation of generating function of Hamilton "relative motion" to the approximate optimal trajectory, improvement of the approximate optimal trajectory was iteratively made. In this way, high order approximation accuracy can be obtained by only using low order approximation, which is much cost effective in computing.

首先以较低的计算代价，获得最优控制Hamilton系统生成函数的低阶近似，得到一条近似的最优轨线，然后将最优控制Hamilton系统相对于近似最优轨线求"相对运动"，该"相对运动"仍具有Hamilton性质，利用这一"相对运动"的生成函数低阶近似，可以对近似最优轨线进行迭代修正，从而以计算代价较小的低阶近似逼近计算代价高得多的高阶近似的精度。

Methods The total cantharidin obtained with acidolysis method and the free cantharidin obtained with direct extraction method were determined in eight species of Meloidae and the control species Huechys sanguinea (Homoptera: Cicadidae) by gas chromatography, and the content of the bound cantharidin in each species was calculated with the content difference between the total cantharidin and the free cantharidin. The relationship between the contents of the bound cantharidin and the contents of Ca and Mg elements in Meloidae were assessed.

These results indicated that a well structured anatase TiO2 was obtained by impregnation method under 500℃. Flow rate, in the activity test, could be neglected for mass transfer effects. As a matter of fact, relative humidity played the most important role in this reaction. The highest removal efficiency was obtained while relative humidify of 56.8%. Water molecules are sources of ; however, excessive water molecules could inhibit reactions by competing activity sites with organic containments. In the regeneration test, photocatalyst could be reactivated through a running water vapor with UV light illumination process.

研究结果指出，以含浸法制备之触媒於500℃锻烧下，具有良好的锐钛矿晶体结构；另外在活性测试的部份，流量的增加，污染物之去除效果不受影响，所以本实验选择以200ml/min之流量可忽略质传影响；湿度扮演重要的角色，当RH=56.8％时去除效率最高，主要因水气是产生氢氧自由基的主要来源，但是过多之水气可能与有机物竞争触媒表面上的活性位置，因而抑制反应的进行；初使浓度对去除率之影响中得知，初使浓度的高低不会影响触媒对有机物的催化能力，实验使用之触媒量适合催化200~250ppm之有机物，可藉由增加触媒量提高对有机物之催化能力；此外再生的测试，触媒可经由连续曝水及紫外光的照射，使触媒恢复原有的活性，可再次利用。
