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。

Though written examination is an important way to the quantitative assessment, it ought to emphasize the understanding of mathematical concepts, the grasp of methods of mathematical thoughts, the ability of mathematical thinking deeply, exploringly and revolutionarily to deal with real problems.

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。

Therefore, the study is significant both theoretically and practically. As a result, the studying aim of this paper is to establish a practical and complete system for the prediction of ship maneuvering motion, taking into account of the influence of the environmental factors, such as the wind, wave and current, establish a practical and complete system for the prediction of ship maneuvering motion. In this paper, the OpenGL virtual reality simulation technique is introduced into the field of ship maneuver and control, and using the MMG mathematical model, the three dimensional dynamic simulation system of the ship motion is established and good results are achieved. In the process of the system development, firstly, the maneuvering motion equations for ship in the still water are established, based on the MMG module mathematical model and serial experimental result. After compiling the program, the calculation results are compared with the experimental data, the coherence between them validate the mathematical model.

在系统开发过程中，首先采用MMG分离式数学模型及相关的系列化试验结果，建立单桨单舵海洋运输船舶在静水中的船舶操纵运动方程，并编制计算程序，经与试验结果比较，证实了计算结果的正确性；为了解MMG数学模型中模型参数变化对操纵性指数的影响程度，作者在上述已有程序基础上，对有关模型参数进行偏移修正，探讨了相应参数变化后的操纵性指数，对船舶操纵性指数对模型参数的灵敏度进行了详细的分析与探讨，所得结论与工程实际相吻合，具有实际应用价值，并为进一步提高船舶操纵性预报的精度打下了基础；然后，在已有的船舶静水操纵运动模型基础上，考虑双桨双舵的影响，建立了内河双桨双舵船舶的操纵运动模型；最后，综合考虑风浪流作用力的影响，进行了船舶的操纵运动仿真计算。
