Firstly, a probe into the dual implications of burden of proof and the expurgation of its intrinsic meaning and result meaning is burden of proof in applied conditions of burden of proof .We should make a definition of applied conditions of burden of proof .The thesis makes a research into the internal structure of applied conditions of burden of proof so as to clearly show the triple contents of its internal structure. In addition, the thesis makes a probe into its regulating mechanism. It points out clearly that applied conditions of burden of proof must ensure the correct application and cautious application of burden of proof.

The fluid film bearing-flexible rotor nonlinear system with squeeze film damper is modeled practically using the finite element method and the Hamilton principle.(3) The film forces produced by fluid film bearing and squeeze film damper are determined by finite element method at any moment, and the Jacobian matrix is also determined.(4) A method for analyzing the dynamics of a large system with local nonlinearities is presented. The stability and bifurcation of the equilibrium position and the unbalance responce of a fluid film bearing-flexible rotor system with squeeze film damper are investigated based on the assumption of an incompressible lubricant together with the long bearing approximation for fluid film bearing, short bearing approximation for squeeze film damper and the"π"film cavitation model.

In the second part, it is argued that the effect of Novum Organum on the philosophy and science is just as the function of beacon. The thesis in this part systematically introduces Bacon\'s basic and extensive thoughts excluding Baconian Induction, Theory of the Idols and the Empirical Epistemology that people have thoroughly researched; moreover, the mistakes which people have made are corrected and the limitations of the viewpoints of Novum Organum are also focused on. In the third part, Bacon\'s basic and extensive scientific and technological researches are discussed. Regarded to this, the thesis finds that people only paid attention to Bacon\'s view that heat is a motion which Bacon took lots of space in Novum Organum to summarized according to Baconian Induction.

本文总共分为四大部分：首先，分析《新工具》是对亚里斯多德《工具论》的勇敢挑战，并着重论述了培根的政治和文化背景对他的新思想所造成的深刻影响；其次，系统探讨《新工具》在哲学和科学中起到的灯塔作用，本文论述了培根的基本哲学和科学思想及具体应用和反映，但是对前人已深入探讨过的培根式归纳法、四假象说和经验认识论不再论述，同时对前人的一些误读进行澄清，并分析培根的《新工具》在哲学和科学思想方面的局限；再次，对前人很少涉猎的《新工具》中的科学研究方面进行系统论述，本文发现人们基本上仅仅注意到了培根在《新工具》中大篇幅运用培根式归纳法进行举例论证的热动说，而对这本书中其他的科学研究不甚关注。

In all, the thesis obtains the following two objects: First of all, the points of view that people have discussed are excluded. Moreover, the thesis concentrates on adding Bacon"s thoughts that people haven"t emphasized, and corrects the mistakes that people have made concerning Novum Organum. At the same time, the thesis evaluates the viewpoints of Bacon and Novum Organum from historical and dialectic angles. Second, combining the contemporary scientific ideology, the thesis concludes that the viewpoints of Novum Organum are great inspirations to the Modern science. In all, this thesis reviews the philosophical and scientific viewpoints of Bacons Novum Organum on the basis of analyzing the materials of Bacon and Novum Organum. The thesis is divided into four parts.

所以，本文欲采用史学研究与哲学分析相结合的方法对前人的见解和培根及其《新工具》本身进行系统的探讨，希望能达到以下两大目的：首先，对《新工具》中前人已着重论述过的思想不再涉猎，致力于补充培根其他哲学和科学思想的研究资料，并剔除对培根思想的一些误读，同时把对培根的评价放入历史的长河中进行具体研究，用辩证的眼光看培根在那个特定时代下所做出的贡献；其次，在对《新工具》中的思想进行研究时，时刻结合当今现实和当代科学思维成果，古为今用，洋为中用，发掘《新工具》对今天的启示。
