Therefore, a revised model of the correspondence view is proposed. It compares textual cohesion and textual coherence in terms of etymology and acceptation, research subject, device and function. A conclusion is reached that cohesion and coherence are two interdependent semantic relations that work at different levels within a text and interact with each other to create textuality.

该模式从语源和语义、研究对象、具体手段和功能等四方面对篇章的衔接和连贯进行了对比，结论认为衔接和连贯是篇章中固有的两种语义关系，都有各自的实现手段，分别在篇章的微观和宏观层次上起着连接篇章成分的作用，相互影响作用，共同赋予篇章以篇章性。

We establish the quantum theory of the one-mode micromaser injected by ultracold V-type three-level atoms with atomic coherence, and discuss the properties of the emission probability, the photon statistics, the spectrum and the velocity selection. We find the following results. There are two sets of peaks in the plot of the emission probability versus the cavity length. The injected atomic coherence can deeply affect the values of the two sets of peaks and the unresonant platform.

Based on electro-characteristic and double electric layers models, directional mechanisms of soy protein molecular are analyzed for the first time on DC heating condition. After the main factors which effect soy protein gels transparency and strength being studied on DC heating condition, the different affects on soy protein gels transparency and strength by DC heating and water bath heating are analyzed and compared, and the transparent mechanisms of soy protein gels are further explored. In addition to temperature action as water bath heating, DC heating is added as electric field directional action. As a results, heating rate is increased. Directional range degrees of soy protein molecules are raised. These advantage the increase of soy protein gels transparency and strength. Microstructures of soy protein gels forming on DC heating condition are observed by SEM and the results showed that ordered structure of transparent soy protein gels on DC heating condition is more ordered than that of transparent soy protein gels on water bath heating condition.
