查询词典 distance circle

When the consistency is checked, the "distance diagram"is employed. It is concluded that the axioms of a description satisfies the consistency iff there are no negative directed cycles in the distance diagram.

在验证ISITL描述的一致性时采用"距离矢量图"，并认为一个ISITL描述满足一致性当且仅当其距离矢量图上不存在负矢量和的有向回路。

The forward kinematics is analyzed by choosing one of the mechanisms which have one, two,three or zero angle constraint.Wherein,3-CCC is a new parallel mechanism which has three angle constraints and three distance constraints, Calay\'s formular and direction cosine matrix are used to describe the rotation matrix respectively.By setting Dixon\'s and Sylvester\'s resultant with the three angle constraint equations respectively and using parameters replacement to deal with the distance constraint equations,the 64 order input-output equation of the forward kinematics is obtained under both of the methods.Numerical example confirms these theretical results and the motion simulation is shown in VC++ by integrating OpenGL.

3对高小山提出的广义并联机构进行了研究，以其中具有角度约束的并联机构进行了分析，选取具有一个、两个、三个和零个角度约束类型中各一个机构进行了运动学正解求解，其中3-CCC是一种全部由圆柱副构成的具有三个线线角度和三个距离约束的新型并联机构，文中分别用Calay公式和方向余弦两种旋转矩阵建模方法对其位置正解进行了分析，通过对三个角度约束方程分别构造Dixon结式和Sylvester结式，以及对三个距离约束方程进行变量代换分别导出了位置正解输入输(来源：4040ABC论文网www.abclunwen.com)出方程，得出64组位置正解，并使用数值算例验证了其全部根。

Second, the so-called thermal expansion will not reduce the disk head and the distance, as head of the aerodynamic principles of flight, under normal circumstances and always maintain a certain distance from the disc.

The factors that affect children's temporal cognitive tact include the effect of teaching and the effect of the concrete life scene. The teaching is the most important factor that decides the children's cognitive development. 6.The children of 4 years old can distinguish the temporal distance information of the future events. During the period from 4 to 6, children's ability to distinguish the temporal distance is in great changes.

影响4～6岁儿童未来时间认知策略的相关因素，主要包括："教学"和"具体的生活情境"，其中"教学"是影响儿童未来时间认知策略发展的主要因素。6.4岁儿童已经能区分未来事件的时距信息，4～6岁儿童区分未来时距的能力存在很大变化。

Long-distance runners from Kenya, Ethiopia and Morocco, playing on the advantage of athletes born and nurtured at altitude, will dominate the distance running events for both men and women.

来自肯尼亚、埃塞俄比亚和摩洛哥的长跑选手，凭借生长在高海拔地区的优势，将揽下男子和女子长跑项目的多数奖牌。

When 2 events occur within a same focal region and the distance between 2 events is far shorter than the distance between events and the station, the ratio of observed spectral amplitudes of the direct P and S phases is linearly correlated with the ratio of their radiation pattern factors, and radiation pattern factors depend on geometrical property focal mechanisms.

发生在同一震源区的两个地震，当地震之间的距离远小于地震到台站之间的距离时，同一个台站的直达P波、S波零频观测谱值之比与其辐射图型因子之比线性相关，而辐射图型因子取决于震源机制解的几何特性。

The 1-4 order variation law of frequency, energy and distance of MS events before destabilizing can display the change rule of MS events. According to the variation law of the difference of frequency, energy and distance of micro seismic events before destabilizing, the fracture of rock mass can be precisely predicted. This is of great importance for safety of colliery.

微地震事件的距离、能量、频数的一到四阶差分均能够显示微地震事件的变化规律，根据未失稳岩体微震事件距离、频数、能量差分变化规律，能够准确地利用微震监测技术预报岩体破裂，这对于采用微地震监测技术解决矿山井下岩体破坏失稳预报具有重要指导意义。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
