The maximum absorption peak was at long wavelength (＞650nm), extinction coefficient achieves 10〓 degree, which was one degree higher than HpD. The study has revealed that CPD photosensitizer appeared blue movement under the relevant body environment. The spectra parameters provided basis for selecting light source of PDT. Measurement system which measured singlet oxygen and its quantum yields within the infare range had been set up and the quantum yields of singlet oxygen for CPD were reported: the quantum yields of singlet oxygen for CPD〓 was the highest (φ=0.83) while he quantum yields of singlet oxygen for CPD〓 was the lowest (φ=0.83). Photobleaching's half life time was studied.

As a result, the achieved uncertainty of time measuring is±125 ps, demonstrating an accuracy improvement in magnitude of an order. The achieved precision of speed measuring is 0.1% of the scanning speed. In hardware design, the intactness of the camera's original structure has been maintained to the very extent, the facility of assembling and disassembling devices have been achieved.

It was found that the practical value of the relative intensity of ultraviolet radiation in the radiation distance of 50 to 100 cm was conincident with theoretical one calcuIated by the square inverse ratio law. In the radiation distance of 25 cm, the practical value was less than theoretical one.

但实际上治疗用的紫外线灯管多为U型灯管，光照强度与光源距离的关系是否仍符合平方反比定律曾有不同意见，为此我们进行了紫外线照射距离改变对强度影响的测试。

In developing such a notion, Newton perhaps had associated some well-known representation (e.g., the light intensity from a radiant objectwas already known to fall off as the inverse square of the distance), and applied it into the field of gravity so as to put forward the inverse square law of gravity as a falsifiable hypothesis.

在建构此观念的过程中，牛顿很可能联想到某种已有的表象（例如，点光源辐射强度随距离递减的平方反比律），并以可证伪的假设形式把它移植到引力情形中来而提出引力的平方反比律。
