查询词典 motions

The stability criteria on the hydrostatics theories are used to estimate whether aship in the heavy seas capsize or not,this method ignores the time domaincharacteristics, frequency characteristics and the randomicity of ship motions. Thecapsizing accidents occur now and then although ships are designed according tostability criterion. So, it is also the important problem for human beings to investigatethe nonlinear characteristics of ship motions and evaluate the survival ability of ships.

目前的稳性标准是根据流体静力学理论来评判船舶在风浪中的安全行为，这种方法忽略了船舶运动的时域特性、频域特性及随机性，按照目前稳性规范设计的船舶仍然时有倾覆发生，因此研究船舶的非线性运动特性和评估船舶航行的生存能力，仍然是人类面临的重大课题。

In this dissertation,the higher order rigid-flexible coupling dynamic model,which isdifferent from the structural dynamics model in the non-inertial reference frame withlarge overall motions known,which takes the coupling between large overall motionsand deformation motion into account with large overall motions being free,and ofcourse which is more accurate than the zero order model,is established for the first time,based on mechanical principles.

本文从力学基本原理出发，针对大范围运动为自由的刚-柔耦合系统，首次建立了较零次近似更精确的高次耦合动力学模型，与大范围运动为已知的非惯性系下的耦合动力学模型不同，进一步考虑了大范围运动和变形运动的相互耦合作用。

Under the condition of not considering the local topology effect and using a simplified layer velocity structure , we obtain the following results:(1) For a vertical strike-slip fault, the stations located on the parallel side of the slip , the transvers component ground motions show faster attenuation than the radial component motions.

对垂直走向滑移断层而言，沿著与断层面走向平行分布的测站，其与断层面走向平行分量的峰值，和其他二分量相较之下，有较明显的衰减趋势；而沿著与断层面走向垂直分布的测站，其与断层面走向垂直分量的峰值，和其他二分量相较之下，有较明显的衰减趋势。

The phase of ω0 frequency fluctuates tempestuously. The resonance peaks of flexural and torsional vibrations response are present at 2/3ω0 1/2ω0 1/3ω0 and 1/4ω0 with three kinds cracked rotor models. Near 1/2ω0 frequency, quasi-periodic and chaotic motions maybe appear. Periodic, quasi-periodic and chaotic motions show on alternately when the rotating speed is near to 2/3ω0.Combined step-by-step integral method with traditional transfer matrix method, an increment transfer matrix method is put forward.

研究结果表明：各种故障情况下，华北电力大学博士学位论文弯振和扭振之间都存在祸合关系，但弯扭祸合振动一般不会威胁机组安全运行：在叶片丢失或滑环飞脱故障时，将产生很大的弯振，同时各转子扭振也将被激发出来，它以工倍频和前三阶固有频率为主；在各种电气故障情况下，各转子都很快被激励出较大幅值的扭振来，相应各转子弯振也发生一定的变化，但它的变化明显滞后于扭振，扭振和扭矩主要以前三阶固有频率为主。

The arbitrator may hear and rule on appropriate dispositive motions as part of the arbitration proceedings, such as motions for judgments on the pleadings, summary judgment or partial summary judgment.

仲裁员在仲裁程序中可进行听证并对有关处置申请作出裁决，如诉状判决、简易判决或部份简易判决的申请。

Firstly the author discusses the model related with "XIANG+NP" event, then analyzes the differences between "XIANG+NP" construction as an adverbial modifier and as a complement. The "XIANG+NP" event can be divided into two types: the factive motions and the fictive motions.

基于路径图式，分别考察了&向+NP&作状语和作补语所表述的事件的内部差异，把事件分为现实位移类和虚拟位移类，并对虚拟位移类的情况作了微观分析，认为虚拟位移类的各个次范畴是在现实位移类基础上的隐喻用法。
