空间运动

Based on the unit quaternion decomposition of rotation matrix, this paper puts forward an algorithm to estimate motion parameters from the space position vectors of 3D feature points.

摘要本文基于旋转矩阵单位四元数分解定理，提出一种由3D特征点空间位置估计运动参数的算法。

Space was a fixed, infinite, unmoving metric against which absolute motions could be measured.

空间是固定的、无限的、静止的度量，而绝对运动可以被测量。

Driven by the combined action of the buoyancy and viscous force,oil drops with the vertical velocity lift rapidly and accumulate at the top of the separation space,which makes oil-water separation at last.

为改善油水分离的效果，利用泵吸产生的负压将含油污水吸入曲板组成的流道内，使油滴在曲面的导流作用下进入分离空间并获得向上的运动速度。

There are seven miles of golden beaches so there is plenty of room to relax by the sea, especially during the summer when you will find activities such as windsurfing , sailing, paragliding , waterskiing, jet skiing and beach volley ball.

长约七英里的黄金海岸线让这里有充裕的空间可以让你放松心情，特别是在夏天，你可以在这里做各式不同的水上及沙滩活动，例如冲浪、帆船赛、滑翔运动、滑水、喷射滑水和沙滩排球等。

The wunderkind, who has a bedroom shelf so full of sporting trophies that there would scarcely be room for an Oscar, appears to have a sense of humour, too.

这个小神童的房间摆满了各式各样的运动奖杯，几乎没有多的空间去放一座"奥斯卡"。

Nature the whole temperatureses are high in the object of absolute zero(-273.15 ° Cs), because of molecular hot sport, all at without intermission to surroundings the space radiation include a red and outside wave band at inside of electromagnetic wave, the temperature relation between its radiation energy density and object matches the gram of Plank laws.

红外温度检测系统自然界一切温度高于绝对零度（-273.15°C）的物体，由于分子的热运动，都在不停地向周围空间辐射包括红外波段在内的电磁波，其辐射能量密度与物体本身的温度关系符合普朗克定律。

A method and an apparatus adaptively encode a motion image based on temporal and/or spatial complexity.

本发明提供一种基于时间和空间复杂性的自适应编码运动图像的方法及其装置。

An excellent athletes should have the ability of professional qualities and consistent all-around play, balanced capacity, attention, the ability of control and adjust emotions, the ability of control and judgment of speed and orientation and other abilities such as anamnestic ability, observation, analysis ability, ideation, the feeling of time and space.

优秀的空中技巧运动员应具有专项素质与协调性的能力、平衡能力、动作表象能力、注意力、适应能力、情绪的调节与控制能力、对自身运动速度和方位的控制与判断能力和其他如记忆能力、观察能力、分析能力、思维能力、时间和空间知觉能力等。

The result may have major therapeutic implications, i.e., any procedure that improves contrast sensitivity would lead to improvements in motion perception in anisometropic amblyopia.

这一结果提示提高弱视患者的空间识别能力就可以改善其对运动刺激的识别能力，对于弱视的临床治疗有指导意义。

To address this question, we cultured a single bifurcated Aplysia sensory neuron making synapses with two spatially separated motor neurons.

为了解决这个问题，我们培养了一个分叉的即能够产生在两个空间上分隔开的运动神经元－－海兔感觉神经元。
