It suggests that there is a regular relationship between PaO_2and its corresponding alterations in hemorheology. The latter may be used as reference criteria to estimate the hypoxemia and the effectiveness of treatment for chronic cor pulmonale with respiratory failure. 作者认为,肺心病呼吸衰竭时PaO2与其血液流变学变化之间存在一定的规律性联系,后者可作为估计肺心病呼衰的缺氧程度和评价疗效的参考指标。
G~ (-++) and G~ (+&) are regular if and only if G is ( n-1)/ 2-regular. We also give some upper bounds on the spectral radius of transformation graphs. Then we estimate these upper bounds. G~(-++)和G~(+&)是正则的当且仅当G是(n-1)/2-正则图.同时还讨论了变换图的谱半径上界,并对这些上界进行了估计。
However, regular structure design cannot exactly reflect local stress-concentrated problem occurred in the brackets, and cannot estimate the hazard at that situation. 用常规理论设计无法反映牛腿节点的局部应力集中问题,对局部应力集中状况不能进一步的明确,对局部应力集中的危害无法准确评价。
Conclusion laceration injury in the skin could induce the expression of the ICAM-1. Moreover, the change pattern of ICAM-1 level was quite regular in relation to time and could be used to estimate the time after skin injury. 结论皮肤钝器伤可诱导ICAM-1表达增加,其时序性变化可望作为一种客观指标用于法医学损伤时间的推断。
It may have over 200 nights for the observation in a regular years from our estimate. 预计正常年景可用夜应在200夜以上。
So we propose improvement DV-Hop ( IDV-Hop) algorithm. We make beacon nodes divide the network into several approximate regular domains through algorithms based on convex hull. So that unknown nodes can choose suitable beacon nodes to estimate their positions in every domain. 对此本文提出一种改进的算法IDV-Hop算法,通过利于基于凸壳的方法将非规则网络划分为几个近似规则的区域,在各个区域内对未知节点进行位置估计。
The Longuet-Higgins distribution is employed to decompose the wave scatter diagram into an individual regular wave scatter diagram, based on which various analyses are performed to estimate the fatigue life of a flexible riser. 基于Longuet-Higgins分布将表征长期海况的波浪散布图分解为单个规则波的散布图,以此进行柔性立管的疲劳分析,并与随机波法的计算结果进行了比较。
