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。

The experimental result shows:1 acupuncture and moxibustion on DU4 and RN4 can lighten inflammationreact , suppress the inflammation course, DU4 has the best result.2 IL-2 is the important factor of participating the immune respondence.Acupuncture and moxibustion can increase IL-2 content in the blood , thusstrengthen the immune function of the organism .3 acupuncture end moxibustion can raise β-EP content of lower thalamus ,hypophysis , lymph gland. it proves that acupuncture and moxibustion can stimulateand accelerate compound、store 、process 、shifting utility of β-EP content; andstrengthen the immune regulating function of the organism, acupuncture function isstrong rapidly, moxibustion function is slow and gentle, the regulating action powerof moxibustion has close relations with choice of the point . The possible reason isthat y whether acupuncture and moxibustion bring into play their regulating actionthrough different way of neural body fluid.4 The DU4、RN4、FEI point influence rule apply on change of β-EP content ofabove-mentioned organism.

实验结果显示：1 针灸命门和关元穴能减轻炎症反应，抑制炎症过程，命门穴效果最好。2IL-2 是参与免疫应答的重要因子，而针灸能增加血中 IL-2 含量，从而增强机体的免疫功能。3 针刺和艾灸可以升高下丘脑、垂体、淋巴结β-内啡肽含量，说明针灸可以刺激并加速β-内啡肽含量合成、储存加工和转移利用；增强机体的免疫调节功能，针刺作用迅速强烈，艾灸作用缓慢温和，艾灸的调节作用强弱还与穴位的选择有密切关系。
