The method of constructing arithmetic of oil system steady model for aero engine has been elaborated in this paper, which is based on the analyses of different parts characteristics that show monotone variation relationship and which introduces the notion "balanced calculation" to replace traditional iteration with vector calculus and various interpolation algorithms.

在分析滑油系统部附件的基础上，根据部附件特性单调变化的特点，提出了"平衡计算"的概念，应用向量运算方法和多种插值算法取代传统的迭代算法来构造航空发动机滑油系统稳态模型算法的思路和方法，并用该算法编制程序对发动机在海平面最大状态下滑油系统性能参数进行了验算。

Applying theories of Vector geometry and differential calculus, this paper aims to infer the internal force and geometry equations for curved beam, whose axis curve is parabola and being distributing-load.

In this new theory system, according to non-inertial tow motion system various multi-linear vector concrete deductive calculus and analyse, it can be determined that after electron and positron collide (combined at shout-range distance reacted by strong force), they form excited state neutrino,then reacted by weak force for a relaxation time becomes un excited state neutrino and release large energy photon or phonon, its mass tends to zero.

新理论体系，按非惯性牵引运动系，各类多线矢的具体演绎矢算分析，可以判定：电子与正电子碰撞(在近程条件强力作用下结合)成激发态中微子后，再在弱力作用下，经一定的弛豫时间，形成非激发态中微子并释放大能量的光子或声子，其质量近乎为零。

It is different from the finite element method which uses the calculus of variation to construct the element-based approximate equilibrium equation. It does consider the equilibriums of forces on the inter-element boundary, which are neglected in the finite element method through the weak formulation.

这种方法跟有限元素法不同，因为有限元素法是采用变分法建立各个元素的近似平衡方程式，这种方法也考虑元素与元素相连接的边界上的力平衡条件，而在有限元素法的推导过程中我们忽略了这种条件。

That failure is a regret that I have, and though the search for prime numbers does not entail the direct use of calculus nor does it solve the meaning of the universe, the chance to work on a problem of purely mathematical abstraction without the need to train oneself for years is appealing to me.

那样的失败的确是我的一大遗憾，尽管梅森素数的搜索不需要直接使用微积分，也不需要解释宇宙的意义。如此纯粹的数学提取工作，又不需要多年的锻炼，这种机会对于爱好理科的我来说是很吸引的。
