空间运动

Low age of girls standing long jump performance depends primarily on the physical length indicators, but also great room for specialized immersion movement capacity is likely to improve performance significantly.

低年龄段女生的立定跳远成绩主要取决于身体长度指标，还有很大提升空间，专门强化训练运动能力有可能是成绩显著提高。

To begin with, we propose an algorithm about motion planning in the state space.

首先在这篇论文中，我们提出一个关於在状态空间的运动规划演算法。

Just as in astronomy the difficulty of admitting the motion of the earth lay in the immediate sensation of the earth's stationariness and of the planets' motion, so in history the difficulty of recognising the subjection of the personality to the laws of space and time and causation lies in the difficulty of surmounting the direct sensation of the independence of one's personality.

正如在天文学上，承认地球运行的困难乃在于否定地球不动而行星运动的直接感觉，在历史学上，承认个人服从空间，时间和因果关系的法则的困难，乃在于否定我们个人的独立性的直接感觉。

The position and the track of stationary and moving point multi-target has been detected successfully.

完成了对靶场测量中的低对比度静态、运动点状多目标的空间位置和轨迹测量的任务。

The Magnetic Stereotaxis System is a unique less-invasive interventional operation device that is designed to deliver a small permanent pellet and an attached catheter directly into the vasculatures or soft tissues of a patient to perform complicated surgical operations under the control of spatial magnetic field distributions.

摘要磁导航外科手术系统是通过计算机控制磁场的空间分布，使预先植入人体内的铁磁小珠按照规定的路径运动，直接作用于患处或引导介入式导管在人体内进行各类复杂外科手术操作的一种新型介入式微创手术装置。

Weaknesses: Defensively Tucker could stand to improve on his intensity … Doesn't seem to possess great anticipation skills nor the awareness to play the passing lanes … Ball handling, while improved, still isn't great … Perimeter shooting remains prone to streakiness … Not a great shooter coming off screens … Solid three point shooter when his feet are set but struggles to hit with regularity due in part to his slow release … Despite being a great athlete, Tucker rarely explodes off the dribble due to his average first step … Doesn't always use the mid-range jumper to his advantage, often he'll slash to the basket or shoot the three … From a position standpoint there is concern about what position he will play in the NBA … While blessed with athleticism, he may struggle to shoot consistently enough to play shooting guard and his height might be a detriment at small forward … While his game has progressed considerably over the past 5 years, one has to wonder how much more he can improve … Below average free throw shooting limits his ability to take full advantage of the contact he creates … BY Matthew Maurer

弱点：Tucker应坚持提高他在防守中的紧张程度。没有让大家看到令人期待的技能。边缘的投射仍然有些忧虑，犹豫。持球能力在提高，但仍然不是很好。。。三秒区也没意识到传球。在脱离掩护后不是名很好的射手。定点时稳定的3分射手。但他仍尽力使自己的得分更加稳定，有规律。很大程度是因为他的慢热。而且作为优秀的运动员，Tucker很少突然运球加速，因为他启动速度不是很快。。。他不总用他中距离跳投的优势，他经常slash to the basket或投射3分。。。他现在很担心忧虑自己将会在NBA中担任什么位置。。。当他有幸得到良好的运动热情，他可能去担当得分后卫而且他的身高不利于打SF。当他过去5年已经有了相当大的进步，人们都对他还有多大的提高空间感到疑问。他低于平均水准的罚球能力限制了他利用身体优势造对手犯规然后得分这种战术的实施。

According to the actual working conditions of bolting-shotcrete supporting in coal-mine tunnel,the working mechanism of different buckets was studied,their merits and demerits were analysed,and the double-crank grab bucket with assistant linkage was proved to be an ideal choice of grabbing materials in coal-mine tunnel because its motion trace was definite and symmetric and occupied lesser space.

从巷道锚喷支护中物料抓取的实际作业环境出发，对拟采用的几种抓斗的工作机理进行了分析研究，比较了各方案的优缺点，指出辅助连杆的双曲柄抓斗的运动轨迹确定、对称，且具有在竖直方向上占用空间最小的特点，是井下巷道施工中物料抓取的理想选择，这种设计方法能够为相关抓取装置的设计起到参考作用。

At the same time balance of the tableau and cut apart form of the beauty andmovement space and coordination of whole be put forward as a specific norm.

同时，画面的平衡、美的分割形式、运动的空间、整体的协调所形成的形式的美感是作为具体的准则被提出来的。

Holding the bow is like a teeterboard supported by thumb as the pivot and the cooperated forcing of forefinger and little finger produces a moment M. The "P-x-M Line Method" shows when playing a down bow, M increases with x and gradually changes its direction and this process is determined by P, the gravity and barycenter of bow. The "P-x-F Plane Method" shows that the most force-saving bowing path should locate in the lower part of this plane. The analyses of "Helmholtz Motion" and "Schelleng Diagram" indicate P and its range is in direct ratio with volume, velocity of bow, the approaching degree of the bow to the bridge and has some relationship with the quality of string and bow.

国内近期出现了用物理模型来研究小提琴运弓问题的尝试本文第一部分首先指出握弓类似于一个以***(F3)为支点的跷跷板，主要以食指(F1)和小指(F2)的施力配合，产生握弓力矩M；随后用"P-x-M直线法"证实：演奏下弓是M随的***而逐渐增大并转换方向的***，此***取决于P、弓的重力和重心；并首创"P-x-F平面法"，在x，F1，F2空间中证实：省力的运弓路径应在该平面中处于较低的位置第二部分通过分析"赫尔姆霍茨运动"和"Schelleng图表"指出：P及其变化范围和音量、弓速、弓与琴码的接近程度成正比，并与琴弦和弓自身的性质有关
