Therefore it is necessary to research the mechanism of greensand used for high compacted molding methods thoroughly.This subject is one section of the National Natural Science Foundation subject ""Ivestigation on Predicting Method and Mechanism of Springback for High Compacted Sand Molds"", followed of the other completed one named ""Research on Microdeformation of Molding Sand"". A serious of experiments has been done on the reequipped three axial machine under certain technological conditions, and the mechanics, material science, rheologic science. It is systematically studied that the influences on the springback of sand mold were caused by the main influence factors: pressure, compacted rate and the content of soil. Through the analyzed experiments' data, the experienced stress-strain relationship concerning the main influence factors were obtained;under different technical parameter, the springback and spingback's potential energy are compared, the differences and indifferences between them are found out, and the springback's mechanism is discussed;according to the tests' data of YangGuoping coming from Tinghua University, experienced formula of molding sand's springback displacement is induced, the displacement and springback are compared, the margin of error's reasons are analyzed, and they are tested and verified mutually.

The new method is given to design the optimum profile modification curve design The effects of optimum profile gear in improving the dynamic performance of gear transmission are verified in the Gear Dynamic Performance Test Rig In this dissertation, the main study contents and creative results are shown as following: The influences on the gear transmission system caused by the gear's accumulated error (periodic error and harmonic error) are theoretically studied. A new method is developed to simulate the gear's harmonic error by using the 2-order MARKOV process A simulated model of the dynamic performance which is excited by the gear's accumulated error is obtained.

Chapter one is on the rationality and necessity of the transition from reflectional method to axiological method to literary theory. The relationship between reflection and value constructs the philosophical basis of the humanities and natural sciences. Nature of literary activities is found by comparison of four aspects: condition, principle, method and process.

先剖析价值论与反映论的关系，指出它们分别构成了人文社会科学和自然科学的哲学基础，通过对二者的前提条件、遵循原则、掌握方法和发展过程的差异的比较，指出人文社会科学与自然科学的哲学基础殊异，而价值论的思考较为贴近文学活动的本质。

No matter the principle of relativity from Einstein's Relativism, Heisenberg's Uncertainty Principle, Bohr's Complementary Principle and Prigogine's Dissipativity Structure, they all tell us that, we can not exclude the human's existence in nature and the important role people play in nature as well.

无论是爱因斯坦的相对论、海森堡的测不准原理，还是玻尔的互补原理、普利高津的耗散结构，都告诉人们，我们不能排除人在自然科学中的存在，不能排除人在自然科学中的重要作用。
