查询词典 inverse-square law

According to by the time series estimate power spectral density\'s periodogram law principle,the research adopts five level of orbital power spectra which US Federal railway Administrative bureau FRA proposed;then,through the Fourier inverse transformation,the orbital not smooth time domain samples are obtained, which determine the track irregularity peak-to-peak value and the corresponding wave length; on the basis of the research,the influence of the wheel track dynamic contact force are considered.Based on the orbital roadbed coefficient\'s definition,computation model is established to solve the roadbed equispaced spring constant,and the roadbed uniform spring stiffness is obtained by using the numerical simulation method.Finally,based on the Matlab procedure platform,the computational procedure is established,and the load time interval caused by the moving train acts on the roadbed is obtained.

根据由时间序列估计功率谱密度的周期图法原理，采用美国联邦铁路管理局FRA提出的五级轨道功率谱，通过Fourier逆变换得到轨道不平顺的时域样本，确定了轨道不平顺的幅值及对应的波长，以此为基础考虑轮轨动态接触力的影响；基于轨道路基系数的定义建立了求解路基均布弹簧刚度的计算模型，采用数值模拟得到了路基均布弹簧刚度；最后，基于Matlab程序平台编制了计算程序，得到了运行列车作用到路基上的荷载时程。

I believe in "The First Law of Petro-Politics," which stipulates that the price of oil and the pace of freedom in petrolist states — states totally dependent on oil exports to run their economies — operate in an inverse correlation.

我笃信「石油政治学第一定律」，它讲的是油价和油国（经济完全仰赖石油出口国家）的自由化成反比。

The recursive least-squares estimation method is used to estimate the parameters in the modelled part of the robot dynamics, and the parameters is used to form the feedback control based upon the so-called"inverse system method". The unmodelled part of the robot dynamics is compensated by a learning control law. This not only increases the learning convergence speed and the control system robustness, but also extends the control method to non-repetitive tasks after sufficient learning.

采用递推最小二乘辩识方法来辩识机器人动力学特性中可建模部分的模型参数，并以此来构成反馈控制策略，而对未建模动特性和未知扰动的影响采用学习控制的方法予以克服，从而提高了学习控制过程的收敛速度和鲁棒性，拓宽了它的适用范围。

A whole new world was dawning on his soul: kindness accepted and repaid, devotion, mercy, indulgence, violences committed by pity on austerity, respect for persons, no more definitive condemnation, no more conviction, the possibility of a tear in the eye of the law, no one knows what justice according to God, running in inverse sense to justice according to men.

一个新天地在他心里出现：接受善行又予以报答，这种牺牲精神，仁慈、原宥，出自怜悯的动机而违反了严峻的法纪，尊重个人，不再有最终的判决，不再有入地狱的罪过，法律的眼睛也可能流下一滴泪珠，一种说不清的上帝的正义和人的正义是背道而驰的。

If control horizon is weighted as usual, it results in constraint control law. Author proposes pseudo weighted control scheme which avoids assumption of inverse stability.

最后，又提出了该模型自适应逆动态组合极点配置控制方案该方案的新颖之处就在于构造非线性增益自适应动态逆，用来补偿非线性增益。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
