The series movement senses of the mafic rocks boudinages and porphyroclasts are from a hand specimen, outcrops to more large size.

一系列运动学标志以手标本或露头尺度，乃至更大规模的镁铁质岩石石香肠或碎斑系为特征。

Three-dimensional dynamic controls of the head, trunk, shoulder, elbow, wrist, ilium, knee, and ankle joints were measured kinematically via a Motion Analysis System, which is consisted of 8 Falcon Analog Cameras. It was found that the high stepping led to a mediolateral increase in the head and trunk swing.

研究的自变项为登阶高度和有无视觉之参与，依变项则为透过动作分析系统(Motion Analysis System with 8 Falcon Analog Cameras)所蒐集之重要关节点的三维运动学资料。

First, based on the analysis and comparison of wave breaker indices defined by geometric, kinetic as well as dynamic stability, which were verified by observation, the value α, which is equal to H/ by Miche' s result and may be modified by Goda' s results, is suggested as the wave breaking criteria. The applicable values of α for pure waves or wave-current co-existing field are given.

首先，基于对波浪破碎的几何学、运动学及动力学三种指标的分析比较和观测资料的验证，本文提出可以合田良实的结果为基础修正Miche的H／=α值，并提出了适用于纯波及波浪与水流共存时的临界α值。

For the space robot system without condition control, according to the principle of momenta conservation, The Kinematic model is constructed using the general Jacobian matrix.

对于载体无位置控制的空间机器人系统，根据动量守恒定律，应用广义Jacobian矩阵建立了系统的运动学模型。

Finite strain measures and kinematic vorticity analysis of deformed granite in mylonitic zone show that ductile shear zone is between plane strain and constraint strain and belongs to lengthening-thinning shear zone. Sub-striking stretch lineation in ductile shear zone and dip strea on brittle fault surface are not result of transferring of lineation but production of different deformations.

糜棱岩带变形花岗岩的有限应变测量和运动学涡度分析显示剪切带总体应变为介于平面应变与拉长应变之间的类型，属一般加长-减薄剪切带；断层系中近走向线理和倾向擦痕不是线理转化的结果，而是不同阶段变形的产物。

Associated with the design of the transplanting mechanism, the principle and approach of noncircular gear mechanism synthesis is investigated deeply.

本文结合插秧机分插机构的设计，深入研究了非圆齿轮机构的运动学综合原理与方法。

The approach of the developed method are, first, the velocity spaces of object and finger joints are, respectively, decomposed orthogonally, and the analytic relation between the object velocity and the joint velocities is derived by means of the kinematics constraints of contacts.

其思路是首先对物体及多指手关节的速度空间进行正交分解并根据接触的运动学约束，建立物体与多指手关节速度间的显式关系。

The statics model of index finger is constructed in order to determine the relationship between actuation torque and the support force from phalanges, which is verified through ADAMS simulation and experiments.
