Then , according to the geometrical optics , the modulation of structure light by the parallel projective illumination and the emanative projective illumination is discussed to educe the height formula corresponding to these two illuminative mode 然后，基于几何光学分析，讨论物体轮廓对平行投影及发散投影结构光场调制问题，导出与这两种照明方式相适应的高度公式。

In the during , the cultivation of the students " creative thought must keep the following principles : firstly , the one of the activation of information , secondly , the one of the sympathetic vibration of wisdom , thirdly , the one of the combination between the emanative thought and the aggregate thought , fourthly , the one of self - inspiration . if you are able to grasp such four principles , then you can carry your reading on , and improve your level of the creative thought gradually 这些都为创造性思维的培养提供了可行性的条件。在阅读教学中培养学生的创造性思维，必须遵循一定的原则:一是信息激活原则;二是智慧共振原则;三是发散思维与聚合思维相结合原则;四是自我激励原则。把握这四项原则，不仅可以确保阅读教学顺利开展，更可以促进学生创造性思维的水平不断提高。

The double - base teaching is one of traditional features in the mathematics " education in our country , which focuses on how to cultivate the students " inquiry ability in the daily teaching . first of all , from the beginning of the double - base teaching , we pay attention to the original knowledge during the teaching of concepts , definitions , theorems and formulas . in the case of exercising lessons , we conclude , summarize and train the student ' s emanative ideations 重视双基教学是我国中学数学教学的传统特色，在日常教学中培养学生的探究能力，应首先从双基教学开始：在概念、定义、定理、公式的教学中注重知识的起源；在例习题教学中，注重归纳、小结及训练学生的发散思维能力；在复习课的教学中注重各知识的相互联系；其次，由于数学开放题具有良好的探究功能，因此，在日常教学中适当创设数学开放题，也是培养学生探究能力的一个重要途径。
