Optical properties of the atmosphere including sky background radiation and surface reflectance are basic physical quantities for atmospheric radiative transfer, light propagation research, and can also find important application in remote sensing, adaptive optics, free-space optical communication, etc.

大气光学特性（包括地表的光学特性和天空背景辐射特性）是光波在大气中传播和大气辐射传输研究必需的基础物理性质，在气象、气候和天文观测等基础和应用研究以及自适应光学技术、自由空间光通讯等光电工程应用中具有十分重要的作用。

A learner can search for the correct starting point ,basing on self-level and the choice of study materials ,the establishment of study goal can be made by his need .In the course of study ,the learner can have a self-reconsideration, have a self-evaluation, and can expand the free space of study activity .

的学习行为起点，学习材料的选择、学习目标的确定由学习者根据自己的学习需要 sSbBwW.cOm 而定，在学习过程中学习者进行自我反思、自我评价，真正扩大了学习者学习活动的自由空间。

In this learning model , in the circumstance of internet , the investigative learning activity of learner is self-antimating ,self-guiding and it must have the definite cognitive inquirment and learning direction ,and it is an internet learning behavior . A learner can search for the correct starting point ,basing on self-level and the choice of study materials ,the establishment of study goal can be made by his need .In the course of study ,the learner can have a self-reconsideration, have a self-evaluation, and can expand the free space of study activity .

WBQ（Web-based Query）学习模式是基于因特网的探究式学习，在这种学习模式下，学习者在网络环境下的探究学习活动是自我驱动、自我引导的，具有明确的认知需要和学习方向，是一种内在的学习行为，学习者根据自身的水平，寻找适当的学习行为起点，学习材料的选择、学习目标的确定由学习者根据自己的学习需要而定，在学习过程中学习者进行自我反思、自我评价，真正扩大了学习者学习活动的自由空间。
