简介：自由民建议的光线的基础功能(RBF)插值途径被用来解决遇到在的反的问题记载得好并且另外的petrophysical问题。途径是根据物理岩石数据集在实验室预言petrophysical性质，它包括形成因素，粘性，渗透，和分子的作文。然而，这条途径不在插值结果上考虑刻度数据的空间分发的效果。这研究基于自由民RBF插值途径，联合起来的基础功能一致地被在空间领域占据建议一条新RBF插值途径。二条途径的反的结果被使用我们的数据集比较地分析。我们决定尽管二条途径的插值效果是相等的，新途径为当数据库大时，减少基础函数的数字更灵活、有益，导致插值函数表达式的简化。然而，当数据簇是差距很大的时，中央数据的预言的结果足够地没满足。

简介：手由五籽骨组成。他们中的二个在metacarpophalangeal(MCP)是在场的姆指的关节。姆指的籽骨骨头的骨折是稀罕损害，光线的方面上的文学很少被报导。我们在姆指的MCP关节与光线的籽骨的破裂报导了一个病人的一个案例以便关于这类损害增加注意。一个44岁的男、高级体操的训练员，当他向右姆指的MCP关节汇报了一处伸直过度损伤时，在锻练期间正在帮助他的运动员之一。在损伤以后的一个星期，他介绍了给在它的手掌的方面上在MCP联合水平抱怨痛苦的姆指的手外科医生。标准A-P和侧面的X光揭示了光线的籽骨的破裂，破裂与一根藤条被对待3个星期。他对有能力6个星期在损害以后恢复了他的全部工作。籽骨破裂伸直过度损害并且有时的大小的指示物与MCP关节的手掌的板系带的眼泪被联系。并且认出系带损害的失败可以在拧上导致长期的伸直过度不稳定性。
