查询词典 holonomic

While, Zeilberger and Wilf [39] showed that proper hypergeometric terms are holonomic and conjectured that the inverse assertion also holds.

所幸的是Zeilberger和Wilf在中证明了正则的超几何项是完整的并猜想其逆命题也成立。

Operations are given and testified in this paper. The research methods of intrinsical linear nonholonomic dynamics are similar to those of holonomic dynamics.The rationality and equivalence of Chetaev model and Vacco model in the intrinsical linear nonholonomic system are testified from the mathematic and mechanical aspects. The essential reason is the nonlinear property of intrinsical nonlinear nonholonomic constrain that bring on Chetaev model and Vacco model inequivalent. Chetaev model is a linear approximate method in intrinsical nonlinear nonholonomic system. Vacco dynamical equations are not satisfied to the ideal constraint force conditions, but it gives a significative ponderation on the realizations of intrinsical nonlinear nonholonomic constrain.

本文比较研究了一般非完整系统的Chetaev模型和Vacco模型，首次从力学和数学的角度论证了这两种模型在完整系统和本质线性非完整系统中的合理性和等价性；同时给出了在本质非线性非完整系统中，Chetaev模型和Vacco模型不等价的根本原因，是由本质非线性非完整约束的不确定性非线性本质所导致的；指出在本质非线性非完整系统中，Chetaev模型是一种线性近似的结果，Vacco动力学方程虽然不满足约束力的理想性质，但是为我们研究本质非线性非完整约束的物理实现提供了有益的思考。

The variational equations are established for holonomic nonconservative dynamical systems in the high-dimensional ex-tended phase space.

建立了高维增广相空间中完整非保守力学系统的变分方程，并利用系统的正则方程和变分方程证明，可由第一积分直接构造系统的积分不变量，并举例说明结果的应用。

It is proved that the model of Hertz, Capon and Lindel"of areidentical to Vakonomic model while the model of H"older, Pars andChaplygin are identical to Chetaev's model. The fact thatVakonomic model and Chetaev's model exist simultanously can betraced back to the early days of non-holonomic mechanics. These twomodels cause two problems the d- and - permutable problems.

论证了Hertz， Capon和Lindel&of的工作与Vakonomic模型相吻合，而H&older， Pars和Chaplygin的工作与Chetaev模型相吻合，Vakonomic模型和Chetaev模型两类模型并存的局面可以追溯到非完整力学发展的初期。1mm说明了伴随两类模型并存的现象而出现的两个问题 d-交换性问题和-交换性问题。

In this thesis, the problems of motion control and perturbance restraint to a wheeled mobile robot with holonomic constraints including uncertain inputs, the pop problems in the field of motion control to mobile robot in recent years, are investigated deeply and thoughtfully.

本文针对近年来在移动机器人运动控制方面的热点问题——包含不确定扰动输入的完整约束轮式移动机器人的运动控制和干扰抑制问题——进行了深入和细致的研究。

At the same time a logic control method is designed to ensure state-switch when robot kinematics axis dissatisfies holonomic constraints conditions.

同时设计了逻辑控制算法保证机器人运动轴在达到完整约束临界点时进行状态切换。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
