A series of reactions may occur when the nitrous acid and naphthalene inside the atmospheric aqueous phases is exposed to sunlight. This article devotes to investigating from a microscopic angle the reaction mechanism and kinetics of this system using laser flash photolysis technique with an excitation wavelength of 355nm. The main research results are listed as below:(1) The OH quantum yield FOH for the photolysis of HNO2 in the aqueous phase was determined to be 0.234 and the absorption spectrum of OH radical was recorded as well.

本文以激光闪光光解为主要研究手段，考察了大气液滴中的HNO2及HNO2+萘体系经355nm紫外光照射后发生的微观反应及其机理，结果表明：(1)液滴中的HNO2经355nm光照产生OH自由基的量子产额为FOH=0.234；以瞬态技术记录了水相中的OH自由基的吸收光谱。

FOI On the one hand require government disclose information generated during the process of governing the society in the proper time and right manner, on the other hand, FOI also means government must meet the claims of the individual to access certain kinds of information.

信息自由一方面要求政府在适当的时间，以适当的方式向民众公布政府在管理社会的过程中产生的信息，也即通常所说的政府信息公开。另一方面，信息自由还意味着政府有义务满足个体获取特定信息的权利。

In the beginning, this article gives a general introduction to FOIA which discusses the means, operation mechanics and exemptions for disclosure prescribed in the act.

其次，文章从三个方面论述了《信息自由法》与媒体的关系：第一，媒体在《信息自由法》的历史上扮演着重要角色。

Even if the material requested under FOIA were exempt from disclosure, the agency might still decide to release it as a matter of discretion.

即使根据《信息自由法》要求的材料属免于披露范围，行政机关仍会以自由裁量为由决定公开发表。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
