They include the fundamental concepts of jet bundle geometry needed in describing time-dependent mechanical systems, decomposition of jet bundles into a direct sum according to the constraints, horizontal distributions on constraint mainifolds, the global formulation of D'Alembert-Lagrange's equations and Chaplygin's equations, and nonholonomic mechanics on a Riemann-Cartan manifold.

本文主要综述非完整约束系统几何动力学的外附型和内禀型Lagrange理论，包括非定常力学系统所需要的射丛几何学的基本概念、射丛按约束的直和分解、约束流形上的水平分布、 D'Alembert-Lagrange方程与Chaplygin方程的整体描述、以及Riemann-Cartan流形上的非完整力学，文中对Chetaev条件和d-δ交换关系的几何意义作了深入讨论。

According to analyzing on the consistent degree of addition modulo 2∧n with XOR addition for commutative law, the computation formulas of the probability distribution of the noise function and the square sum of the probability values were presented, which is applied on the distinguishing attack on Py. The data complexity of our attack is about 2019∧（-1）times of the data complexity of the distinguishing attack on Py proposed by Sekar et al..
