  • 简介:在二维的空间R2的bivariate插值在一维的空间R是比那更复杂的,因为没有在R2的连续功能的Haar空间。因此,bivariate插值没为一套任意的不同pairwise点有一个唯一的答案。在这个工作,我们建议取决于点的基础的一种类型以便bivariate插值为不同pairwise点的任何集合有唯一的答案。在这种情况中,bivariate插值的矩阵把半继承因式分解。

  • 简介:AbstractThe year 2020 is an extremely unusual year. The world lost more than one million lives due to the attack of COVID-19. Economic production has been greatly reduced, and daily activities are largely restricted. Luckily the work of Chinese Journal of Traumatology (CJTEE) has not been adversely affected. 2020 is a harvest year for the journal, which (1) was included in the high-quality academic journals by China Association for Science and Technology; (2) cover of each issue is newly designed; (3) submission increased by about 60% with more countries and regions covered; (4) usage in the ScienceDirect database exceeded a million; (5) the CiteScore rises to more than 2.0 the first time. This study reviewed the articles published in the year 2020 by CJTEE.

  • 简介:AbstractTrauma is the leading cause of death in people under the age of 45 years, and it has gained wide attention from academics worldwide. Therefore, more and more studies have reported on trauma and related fields in recent decades. In 2019, Chinese Journal of Traumatology (CJTEE) published 69 articles covering traffic medicine, wound healing, bone trauma, emergency care, and other hot topics of traumatology. Here we reviewed a series of articles published in CJTEE on the topics mentioned above, try to give a brief introduction of progress in trauma field.

  • 简介:基于的一个格子和Green-Ampt(Grid-GA)散布了hydrologic物理模型为洪水模拟被开发并且在半潮湿、半干旱的盆预报。基于从数字举起模型(DEM)和Green-Ampt渗入方法提取的每个格子房间的地形学的信息,Grid-GA模型考虑水内容的再分配,并且由植被和根拦截组成,土壤水分蒸发蒸腾损失总量,经由过量渗入机制的流量产生,流量集中,并且流动路由。土壤潮湿的下坡的再分配明确地在一个格子基础上被计算,并且沿着网络被考虑的河排水在流量路由以内在格子之中浇交换。建议模型和Xinanjiang模型在Luohe河里被用于上面的Lushi盆,黄河的一条支流,与为洪水模拟的4716km2的一个区域。结果证明两个模型在洪水模拟表演很好并且能被用于洪水在半潮湿、半干旱的区域预报。
