查询词典 compensated pendulum

In the study of the stochastic chaos in simple pendulum, the random Melnikov process is derived and the mean-square criterion is used to determine the threshold amplitude of the bounded noise excitation for the onset of the chaos or random chaos in the system. For the coupled simple pendulum and harmonic oscillator, the Melnikov function is used to determine the condition for the onset of chaos in the case of Hamiltonian perturbations. In the case of non-Hamiltonian perturbation, the generalized random Melnikov process and mean-square criterion are used to determine the threshold amplitude of the bounded noise for the onset of random chaos.

在随机混沌研究中，应用随机Melnikov过程的均方准则研究了单摆在有界噪声激励下发生混沌或随机混沌时有界噪声激励的临界幅值；对于耦合的单摆-谐振子系统，先用Melnikov函数研究了在哈密顿扰动下发生混沌的必要条件；然后用推广的随机Melnikov过程方法研究了在非哈密顿扰动下发生随机混沌的必要条件；用最大Lyapunov指数及Poincaré截面方法结果与上述理论结果作了对比。

通过对比研究发现，本次参赛选手在三跳中采取的摆臂姿势为：单足跳为单摆臂、跨步跳为双摆臂、跳跃为双摆臂。

"We were looking at the slow steady swing of the pendulum as it counts the seconds," the younger one said,"and my friend has said it would be easy to stand in front of the clock for one hour, to stand without moving and say 'here it comes, there it goes' as the clock's pendulum swings back and forth."

"我们再看钟摆慢慢摆动计算时间，"年轻一些的人说道，"我朋友说在钟前站一小时很容易，要站着不动，还得在钟摆摆动时说：'摆过来，摆过去'。"

A switching control scheme is presented for an underactuated Furuta pendulum system, which consists of an actuated arm and an unactuated pendulum.

针对由一个驱动臂和一个未驱动摆杆组成的欠驱动Furuta摆系统，设计了实现其稳定的切换控制系统。

The technical characteristic of a pendulum drill assembly is to lose "penetration rate"in order to get"dropping angle", but sometimes a pendulum drill assembly can't meet the need of drop—off hole angle, which results in longer completion well cycle and more drilling cost.

防斜打直是常遇到的钻井技术问题，防斜的钻具组合是满眼钻具，纠斜的钻具组合是钟摆钻具，当满眼钻具满足不了井斜控制的要求，就必须强迫起钻换钟摆钻具，而钟摆钻具的技术特点是损&快&保&直&，有时还达不到纠斜要求，导致较长的建井周期和较高的钻井成本。

In the first part, study 1 was designed to investigate the development of the science inquiry ability in the group of the primary and secondary School student, and how the task difficulty affects science inquiry. We used the self-directed, computer simulated inquiry task, namely pendulum and string task It required the subjects to find the factors that affected the swing frequency of the pendulum and the level of stretch of the string. To evaluate the ability of science inquiry, we analyzed subjects'experiment-design strategies, evidence-evaluation strategies, and results of inference.

实证研究分两部分，第一部分即研究一，采用计算机模拟的自我指导实验探究任务，任务内容为单摆实验和弹簧实验，要求被试自主探究影响单摆摆动频率和弹簧伸拉长度的因素，并以科学探究的全过程为研究对象，以被试探究中的实验设计策略水平、证据评价策略水平以及正确推论结果作为衡量科学探究的指标，系统探讨了小学高年级和初中学生科学探究的特点。
