Under using the different night temperature conditions in two glasshouses,the experiment was conducted to study the effects of night temperature on growth and yield of early-season rice during the whole growth period.

【Objective】To investigate the response of fruit endogenous hormone to different night temperatures and the relationship with fruit development, the effects of different night temperatures on the content of endogenous hormone were studied.

To probe into the response of endogenous polyamine to temperature stress and the relationship between endogenous polyamine and fruit expansion,the effects of different night temperatures on fruit expansion and polyamines were analyzed with Cucumis melo L.

On variation of visibility and air pollution in Meizhou Bay;

Lanzhou Aerosol Optical Depth in Winter and Their Relation with Visibility;

Analyses on Variation Trends of Atmospheric Visibility and Its Effect Factor in Muilt-Cities in Central Liaoning;

So using continuous spectrum sun-photometer and forward scatter visibility sensor, we measured the atmosphere column optical characteristic and plan extinction coefficient on earth on the base of two experiments, respectively.

The intensity of forward-scattered light is measured by the forward-scattering visibility sensor, which determines the extinction coefficient of the air, then the visibility can be obtained.
