环境变量

Three types of learning supports were designed accordingly, interpretative support that helped learners with knowledge access and the generation of integrative understanding, experimental support that scaffolded learners in the systematic and logical design of experiments, the prediction and observation of outcomes, and the drawing of conclusions, and reflective support that increased learners' self-awareness of the thinking and understanding processes and prompted their reflective abstraction and integration.

作者以实验方法集中考察了反省性支持的效应，结果表明，反省性支持在知识整合和变量控制技能等后测上具有明显的作用，这种学习支持应该成为模拟环境中的一个重要支持措施。

To investigate the adsorption and desorption behavior of compound feeds, Guggenheim-Anderson-de Boer equation and modified GAB were applied to fit the equilibrium moisture content data of adsorption of a pelleted finishing broiler feed at equilibrium relative humidity from 0.11 to 0.97 and the desorption at water activities from 0.11 to 0.75 at 15℃, 25℃, 35℃ and 45℃, obtained by the conventional static gravimetric method.
