METHODS: The endodontic instrument was assumed as a metal conical bar. The normal stress of bending loads and the shear stress of torsional loads were calculated with the knowledge of mechanics. The relations between stress and such parameters as angle and radius of canal curvature, radius of instrument, polar moment of inertia, and metal elastic modulus were analyzed. The criteria for yielding and fracture of the instrument were discussed.

Since the set of the centres of these balls is finite, it has finite diameter, from which it follows that every totally bounded space is bounded.

因为这些球的中心的集合是有限的，它有有限半径，从而得出所有完全有界空间是有界的。

While the installation intends to record rain in the tangible form and trace all the possible factors which may influence the result of the performance such as the power and direction of the wind and the weight of the rain drops, etc.

地球外部作用于此时此地的因素，日出日落时间，太阳系的行星运动，银河系的变化，总星系中的平均质量密度，宇宙的场强、宇宙常数、哈勃常数的测定，膨胀系数和年龄，宇宙的中心与半径、红移等，把这些外界影响记录做出照片作为作品的一部分。

In this field, Christian et proposed a Island method in 2005, it is a k nearest neighbor query method of moving objects based on road network,but this method has three flaws which are k nearest neighbor query in constrained road network,traffic-jam exploration and optimize of Island's radius. This article has studied k nearest neighbor query of moving objects based on road network in view of above three aspects ,and proposed the Island+ method, which has made the improvement to the memory structure and trajectory preservation of neighbor objects.

在这一领域，Christian等人在2005年提出了Island方法，它是一种基于路网的移动对象k近邻查询方法，但是这种方法存在以下不足的地方，第一，该方法对路网没有任何限制条件；第二，没有给出明确的数据存储结构；第三，区域半径一致，效率不高。
