The only effect is the appearances, in the axial response, of the higher order superharmonic components of even-time working frequency at low rotating speeds.

分析表明，非线性涡轮叶尖间隙流体激励力对转子轴向碰摩的非线性特性影响不很明显，只是在低转速时轴向振动碰摩响应中会出现更高阶的偶数倍频的超谐波成分。

Ankle Foot Orthosis is usually applied for stroke patients to prevent foot drop during swing phase, and provides some range of ankle dorsiflexion after mid stance phase on walking. These conditions cause cyclic tensile and compression force on the AFO, and result in breaking or tearing of AFO after several weeks or months usage. Therefore, it is important for therapists to know what geometric modification of AFO can prolong its usage. The purpose of this study was to develop a motion simulator for observing the effect of simulated heel strike impact and foot dorsiflexion on the AFO. The geometry of motion simulator was designed similar to human leg.

足踝副木经常被使用在中风患者下肢以避免走摆荡期发生垂足现象，同时，副木於站期中期后也能提供些许的踝关节背曲角，此一况导致副木遭受循环的张与挤压，常於星期或个月的使用后，导致副木疲断或撕，因此，让治师解副木的几何外型改设计能延长使用时间是很重要的，也因此，本研究目的为设计一评估副木疲破坏的运动模拟器，用以观察副木遭受模拟的脚跟著地冲击与足踝跖曲与背曲弯折对副木的效应。

The histological data demonstrated that the impact could produce damages of both of TMJs. Hemarthrosis and destuction of the articular discs and the cartilage of the condylar process and glenoid fossa were observed. The greater force was, the more obvious destruction was found. The changes of the TMJs after indirect trauma are similar to humans.

结果发现，颏部撞击可引起双侧TMJ的间接性损伤，包括关节积血、髁状突、关节盘以及关节附着和颞骨关节面等破坏性改变，撞击力越大对关节结构的损伤越重，这种破坏性改变与人类TMJ损伤后的表现相一致，病变较典型，致伤方法可靠。

The electromagnetic force opposite to the fluid flow is also produced, which makes less impact on the narrow side shells, and results in a pluglike flow in the region under the lower pole of the magnetic field.

计算结果表明，结晶器内流动的钢液在恒稳磁场的作用下，形成了具有封闭回路的感生电流，其主体部分从板坯宽面一侧大范围地向另一侧流动，中途逐渐变大，并绕过水口流动。

Based on a historical review of theoperational modes of the rural administrations, this paperstudies the role of local rascaldom as a social force, itsorigin and its destructive impact on the grassroot- leveladministrations in China's villages.

在简单回顾了历史上乡村行政的运作模式之后，文章依照历史的脉络，重点对乡村地痞这一特殊角色群体之于当代中国农村基层行政的影响进行类型学的分析，认为其各种作为必然破坏国家的统治基础，动摇政权的合法性。

It is testified if the time reversed seismogram were used as the loading curve and an efficient source of force were exerted on the rock at the seismographic station,then artificial input energy will focus on the hypocenter and cause an intense impact,therefore an earthquake would be touched off.

模拟结果表明，如果将地震图进行时间逆转后，作为加载曲线，在地震台站点上通过一个有效的力源加载于基岩，利用时间逆转效应，可以将人工施加的能量在某一瞬间集中到以往的震源，引起一个强烈的冲击，因而可能触发地震。

In this article, We consider two important models for second order sublinear differential equations: the existence of infinitely many subharmonic solutions for Duffing equation with bounded restore force and for the sublinear impact oscillator.

本文考虑被数学和其他科学、工程领域的研究人员广为关注的两个重要的二阶次线性微分方程模型：具有有界恢复力的Duffing方程和次线性碰撞振子的无穷多个次调和解的存在性。

In this article, We consider two important models for second order sublinear differential equations: the existence of infinitely many subharmonic solutions for Duffing equation with bounded restore force and for the sublinear impact oscillator. They have attracted lots of researchers attention in mathematical, other scientific and engineering fields.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
