The main points of his ontological interpretation are as follows:As mente concipere,a project of thingness which,as it were skips over the things,The mathematical is the consequence of a mode of Dasein,is the nature of the mathematics and modem science;modem science is based on the mathematical of the modem metaphysics;objective truth is not original;The debate between objectivism and subjectivism is the result of the reign of mathematical Dasein.

科学危机不代表着理性本身有问题，而是表明需要正当使用理性。超验主义是拯救危机的真正道路。在存在论视域下，近代科学之数学特征具有存在、真理和工具三层面意义。海德格尔认为客观真理论和工具论虽然是正确的，但是肤浅的。

The main points of his ontological interpretation are as follows:As mente concipere,a project of thingness which,as it were skips over the things,The mathematical is the consequence of a mode of Dasein,is the nature of the mathematics and modern science;modern science is based on the mathematical of the modern metaphysics;objective truth is not original;The debate between objectivism and subjectivism is the result of the reign of mathematical Dasein.

海德格尔进一步指出，近代科学的数学因素本质决定了它的所谓不思性。这不是说它没有思维，而是强调它只是计算性思维，不是沉思之思，因而不能认识自身。

笔试仍是定量评价的重要方式，但要注重考察对数学概念的理解，数学思想方法的掌握、数学思考的深度、探索与创新的水平以及应用数学解决实际问题的能力等。

I think, via research, during the period of middle school, the application form of mathematical history in concept teaching should be "the form of being in harmony"; and we should choose the suitable mathematical history content according to the teaching content and the students' perceive; we should obtain concept through paying more attention to the latitudinous teaching and recreating principles; presenting the outcoming process of mathematical history through sight principles; improving the degree of the students' attaching themselves to the process .

中学阶段，数学史在概念教学中的应用遵循的原则主要有：应用形式为&融入式&为主；根据教学内容和学生的认知选择合适的数学史内容；在应用时应注重认知纬度的教学；遵循再创造的原则获得概念；遵循直观性原则呈现数学概念的演变过程；采用灵活多样的教学方式，提高学生的参与程度。

Aiming at a class of complex electromechanical systems, such as 4-high or multi-high cold mills and continual mills, we firstly construct mathematical models of every subsystems by means of structural principle modeling method; nextly, get the overall mathematical model of electromechanical drive system by joining together these subsystems'models according to coupling variables and parameters; we finally simplify the overall model according to time-scale principle which can retain main eigenvalues and significant state variables, and obtain a practical mathematical model of complex electromechanical system. By simulating the CM04 temper mill's model constructed by above-mentioned method, we test and verify that the modeling method is effective and practical.
