查询词典 of the moment

At first, according to the mechanical vibrationtheory and detailed analysis on coiling the different stage mathematical models of coiling are set-up. The correlation equations of the models are also given. Then, the paper presents an analysis ofthe moment of inertia of coiler in hot strip mill in detail, the equation of the inertia moment and theanalysis.

本课题首先从振动理论出发，对卷取的整个过程做了详尽的动力学分析，建立了不同卷取阶段的数学模型；接着分析了卷筒的惯性力矩，建立了卷筒张力控制的数学模型，推导了惯性力矩的理论表达式。

Close the valve, the need to open and close with the Coma Berenices two pieces of the sealing surface of the seal formed between certain specific pressure, while also overcoming the stem and the packing between the stem and the nut thread between the stem end bearing at and other friction parts of the friction, and therefore must apply the closing force and closing a certain moment, the valve in the open and close the process, the required hoisting hoisting force and moment of change, and its maximum is close to the final instant or open the initial transient.

关闭阀门时，需要使启闭件与发座两密封面间形成一定的密封比压，同时还要克服阀杆与填料之间、阀杆与螺母的螺纹之间、阀杆端部支承处及其他磨擦部位的摩擦力，因而必须施加一定的关闭力和关闭力矩，阀门在启闭过程中，所需要的启闭力和启闭力矩是变化的，其最大值是在关闭的最终瞬时或开启的最初瞬时。

This paper adopts auto-threshold value technology which can select better threshold value. This paper puts forward rotating projection moment invariants which optimizes moment invariants and identifies conglutinate letters.

本文采用了自动阈值选择技术，使阈值的选择更合理；对不变矩进行了优化，首次提出了旋转投影不变矩方法，适合粘连字符地识别。

Week 4 Work and energy principle, conservation law of mechanical energy, moment of force, moment of inertia of rigid body, rotating law of rigid body with fixed axis.

第4周 功能原理、机械能守恒定律；力矩、刚体的转动惯量、刚体定轴转动定律。

It must be pointed out that not only the conceptual model of GeoFeature-CA is standing at the moment of academic studying and has great continuative studying space but also GFCA-Urban model is standing at the moment of practical study and the precision and authenticity of GFCA-Urban model need improved.

必须指出的是，GeoFeature-CA概念模型还处于理论探讨阶段，留有巨大后续研究空间，GFCA-Urban模型也还处于尝试性研究阶段，模型的精度和真实性尚待提高。

We see the same thing, watching moment by moment the movement of historical personages (that is, restoring the inevitable condition under which all action takes place—the condition of the continuity of motion in time), and not losing sight of the necessary connection of historical figures with the masses.

假如我们每时每刻注视历史人物的运动（就是恢复所发生一切的必要条件——运动在时间上的连续性），不疏忽历史人物和群众的必要联系，我们就会看见同样的情况。

The results indicate that the weak election-withdrawing group 4-hydroxymethyl in 4-position of pyridine in 4-HMDPA could weaken the fluorescence intensity of the lanthanide complexes. The contradistinctive experimental results show that the fluorescence intensities of these complexes are related to pH value of the aqueous solution and the dipole moment of solvent molecule: in the neutral aqueous solution,the fluorescence intensities of these complexes were strongest,while the less the dipole moment was,the stronger the fluorescence intensity was.

结果表明，在吡啶4位引入弱吸电子基团4-羟甲基会减弱稀土配合物的荧光强度；在水溶液中稀土配合物与溶液的pH值有着密切的关联，中性水溶液中荧光强度较大；分子偶极矩较小的溶剂中稀土配合物荧光强度较强。

It belongs the kind of complex bridges because its liner changes usually and the weight condition is also complex, except bear moment and shearing force, there are larger torsion and doubled moment, as a result, crankle、warping and aberration would happen.

这种异形桥梁结构是受力很复杂的一种桥型，其线性变化多端，结构受力复杂，除承受弯距、剪力外，还有较大扭矩和翘曲双力矩的作用，即使外荷载的作用通过梁的剪切中心，也将发生弯扭组合变形，同时伴随有截面的翘曲和畸变。

This paper has also derived the unit stiffness matrix of bar element on which the moment of some nodes is over the elastic ultimate moment and discussed the convergent properties of computing method.

把水压机活动横梁假设成一交叉梁系，对其做了弹塑性有限元分析，导出了部分节点弯矩超过弹性极限时的梁单元刚度矩阵，讨论了计算方法的收敛性。

The circulation, consumption and reproduction of the trilogy have not only testified to its historical significance and literariness, but also invested it with new meanings.

该三部曲的流通、消费与再生产不仅验证了其历史意义及文学性，而切还赋予它以新的意义。

If he thought that he could buy me off, he would be wrong.

如果他认为他可以收买我，那他就大错特错了。
