空间运动

Even Newton's laws are preceded by eight definitions and a "scholium", or explanatory comment, asserting that space, time and motion are absolute.

即便是牛顿定律，也是建立在8条定义和一项注释基础上的，这项解释性注释说空间、时间及运动都是绝对的。

It shows that all these effects have significant influence on the seismic response of the structure.

结果表明，地震地面运动的空间变化效应对结构的响应有着较明显的影响。

It is a working hypothesis of this paper that nowhere else within the broad spatial and temporal range of this prolonged, far-flung revival, with the possible exception of Revolutionary France, was there such an intense, self-revelatory florescence of this movement as occurred during the early decades of our national existence.

本文的暂定假设是，我们国家存在的早期几10年间，在这个持久、遥远复苏的广阔空间与时间范围内，没有其他地区，可能除了革命性的法国之外，能发生一个如此强烈、自我启示的目盛期运动。

A dynamic active contour model for spatio-temporal trajectory is proposed to track robotic manipulator motion in image sequence space.

针对机械手运动在图像序列空间的轨迹分布，提出一种基于时空轨迹线的动态Snake跟踪模型。

In order to probe the absorb coefficients of earth medium by the direct wave, reflected wave and transmied wave amplititude which are picked up from the radar wave racords yielded by finite element method,the paper gives out the attenuated radar wave equations in time domain and the attenuated radar wave differential equations while the motion changes simple harmonic with time and electric parametets change slowly with space.

摘 要 为了用有限元方法生成雷波正演记录，从而拾取直达波、反射波、透射波振幅信息，以确定介质吸收系数，文章在时间域给出了雷达波含衰减项的波动方程，及在运动随时间简谐变化以及电性参数随空间缓变的条件含衰减项的雷达波遵循的简化微分方程。

It is also varified that completely unbent position is a only singular point in the whole workspace of a finger.

根据手指的运动特点和关节力矩传感器的配置情况，得到了手指的速度雅可比和力雅可比，并由此证明：手指完全伸直的位置是整个工作空间内唯一的奇异点。

Two kinds of three-branch space robot mechanism were described.

提出了两种三分支的空间机器人机构，并对其运动进行了分析。

The problems of capturing a moving target for space robot are researched.

本文提出了基于轨迹规划的自由漂浮空间机器人抓取运动目标物体的研究方法。

Fourth, a novel three-branch space robot mechanism was proposed and analyzed.

第四、提出了一种新颖的三分支空间机器人机构，对该机构的运动进行了分析。

Pem gene is expressed in a time and stage specific manner. Pem transcripts are detectable as early as day 6 in mouse embryonic development, and are abundant in day 7 and 8, but decrease precipitously thereafter. Although Pem transcripts are not detectable in most of adult tissues, they are present in reproductive system. Furthermore, Pem has also shown to be specifically expressed in the proximal cauda and distal corpus regions of the epididymis, the regions where spermatozoa gain forward motility and fertilization competence.

Pem基因的表达具有明显的时间和空间特异性：在鼠胚发育的第6天，即可检测到Pem转录本的表达；第7-8天，Pem表达量达到最高，随后迅速减少；Pem基因在成年组织中一般不表达，但可在生殖组织表达；另外，Pem特异地在附睾近侧尾部和远侧的体部中表达，此处是精子获得运动性和受精能力的地方。
