Dr. Wu will continue his laboratory measurements of low temperature absorption cross sections of molecules of interest in the study of planetary atmospheres, comets, nebulae, and interstellar clouds. The measurements are made in the near visible through the ultraviolet region of the spectrum. The pressure, temperature, and relative abundance of the sample of gas of interest will be chosen to simulate realistic planetary conditions. Accurate knowledge of photo-cross sections of relevant molecular systems is essential for understanding the dynamics of photochemical processes in our atmosphere and those of the other planets. Dr. Wu's measurements deal with the spectral range where there is plenty of radiation from the Sun, and they are extremely relevant for the interpretation of phenomena occurring in planetary atmospheres that are stimulated by ultraviolet radiation.

吴博士将继续他的低温实验室测量 研究中感兴趣的分子的吸收截面 行星大气、彗星、星云和星际云。 测量是在近可见的通过 光谱的紫外线区域。 压力、温度和 将选择感兴趣的气体样品的相对丰度 来模拟真实的行星环境 相关分子光截面的准确知识 系统对于理解 光化学过程在我们的大气和那些其他 星球 吴博士的测量涉及光谱范围， 有大量来自太阳的辐射，它们非常 与解释发生在行星上的现象有关 受紫外线辐射刺激的大气层。
