With the theory, any straight lines and quadratic curve′s equidistance curve can be indirectly interpolated with the help of outline and wire circle′s information, it is unnecessary to calculate equidistance curve .

该理论直接利用轮廓曲线和丝圆的信息，不需计算等距曲线，间接实现任意直线和二次曲线的等距曲线的插补，有效地避免了传统计算等距曲线产生的计算误差，简化了数控机床控制程序设计，提高了机床的控制精度。

In this paper,a rational approximation method of the norm of parametric speed is given,which is more effective than the polynomial approximation.

文章根据等距曲线逼近的关键在于对其参数速度模的逼近，提出了对参数速度模有理逼近的2种形式，在此基础上给出了平面Bézier曲线等距曲线的逼近函数和误差估计函数，并导出了保持法矢平移方向的代数方式的等距有理逼近算法。

Methods: 12 fresh frozen shank-foot specimens from young adults were observed. The tibia was fixed rigidly. The talus and navicular were marked. We exerted different load on the forefoot for keeping it in different motion patterns and measured the three-dimensional coordinates of the marked points on these bones. The relative 3D motion range of the talonavicular joint was calculated. The characteristics of the talonavicular joint and the forefoot and their relationship were analyzed.

采用12例新鲜青壮年小腿足标本，牢固地固定胫骨，标记距骨和足舟骨，分别对足前部加载不同的负荷，使前足处于特定的不同运动状态，用三维数字化仪测量标记点的三维坐标值，计算距舟关节的相对三维运动值，分析距舟关节和前足的运动范围及两者间的关系。

In this paper,the rational approximation of the offset curve of Bézier curves is obtained when a polynomial of symmetric power basis is used to approximate the norm of parametric speed of Bézier curves.

等距曲线逼近技术的关键在于参数速度的逼近，文章用S幂基多项式逼近平面Bézier多项式曲线的参数速度模长，得到Bézier多项式曲线的等距曲线的有理逼近曲线，所得有理多项式逼近曲线与等距曲线在端点处能够达到高阶插值。

Anatomic classificationof ankle sprains is based on the number of affected ligaments.First-degree sprain is characterized by a partial or completetear of the anterior talofibular ligament. In second-degreesprain, both the anterior talofibular and calcaneofibular ligamentsare either partially or completely torn. Third-degree sprainconsists of injuries to the anterior talofibular, calcaneofibular,and posterior talofibular ligaments.

踝扭伤的解剖分型是根据受累的韧带进行的。1度扭伤的特点是前距腓韧带的部分或完全撕裂。2度扭伤是前距腓韧带和跟腓韧带同时部分或完全撕裂。3度扭伤是前后距腓韧带和跟腓韧带同时损伤。

The morphemic order and the degree of fusion are not arbitrary, in that the categories that most affect the meanings of the stems occur closest to the stem, whereas those that have least impact on the lexical meaning of the stem occur in the periphery.

此项假设认为构词法中语素和语素之间的结合方式、先后次序和远近关系是任意的﹕凡是影响语根之语意变化最直接、最全面的语意范畴，在距上一定最接近语根，相反的，影响语根之词汇语意变化最小的语意范畴则远语根，所以衍生词缀距语根较近，而屈折词缀距语根较远。

In the experiment section, there"re three experiments investigating implicit attitude and dual-attitude model. In the first experiment, the author studies the effects of attitude strengthen on attitude"s automatic activation effect. In the second experiment , the author studies the effect of delay condition on the attitude"s automatic activation effect. Delay condition make experiment approach to mere exposure of attitude object, and two experiment demonstrate attitude"s automatic activation effect is the result of noncognitive processing.

第一个实验，探讨了态度强度对态度自动激活效应范式的影响，结果发现态度强度不是影响态度自动激活效应的因素；在第二个实验中，探讨了时距对态度自动激活效应的影响，时距控制使得实验更接近于态度物的单纯呈现，结果发现时距没有对自动态度激活效应产生影响，从而论证自动态度激活效应可能是非认知系统作用的结果，具有普遍性。

The text obtains some data that caving span of immediate roof is 30m, caving span of main roof at first weighting is 42m and caving span of main roof at periodic weighting is 14m. Mining influence range is determined about 40m through numerical modeling, namely about three advance pillars were in the range of mining influence.

利用数值模拟得出煤柱采场直接顶的垮落步距为30m，老顶的初次来压步距为42m，老顶的周期来压步距为14m；通过模拟超前支承压力，确定了采动影响范围约为40m，即采场超前的三个煤柱都在影响之内。

The correlated distances of bottom soil watercontent at different times were bigger than those of surface soil. Soil salt content did not have thisphenomena. The possible reason was that the bottom soil salt content was mainly affected bygroundwater.

两个时期土壤底层含水量的自相关距都要大于表层的自相关距，而盐分的空间自相关距没有表现出这种现象，这可能与底层盐分受到地下水作用的影响比较大有关。

A maneuvering mathematical model for Controllable-Pitch Propeller ships with three degrees of freedom is established according to separate modeling theory. Based on Netherlands Ship Model Basin\'s open-water tests, CPP thrust coefficients and torque coefficients in four-quadrant with different pitch ratio of screw and different types of CPP are obtained by using Akima interpolation. Therefore, CPP thrusts and torques are obtained.

基于船舶操纵性分离建模理论，采用荷兰船模试验水池B系列螺旋桨的敞水试验结果，利用Akima插值获得了不同类型的调距桨在不同螺距比下的四象限推力系数和扭矩系数，求得调距桨的推力和扭矩，建立了调距桨船舶的平面运动数学模型。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
