In this paper, 4 variables of the distal tarsometatarsus were also collected from 25 specimens of fossil birds belonging to 14 genera of Early Cretaceous birds from Western Liaoning in China. Analyses of these variables have also proven to be useful in distinguishing arboreal and terrestrial birds, and the result is generally consistent with a conclusion reached on the basis of other analysis, i.e. those based on the claw geometry and toe proportion.
通过对在中国已发现的25例中生代鸟类跗跖骨远端4个变量的统计分析,表明它们同样具有区别树栖和地栖鸟类的显著意义,而且分析的结果与参考鸟类其他特征(如爪的形态、脚趾的比例等)所得出的结论基本一致。

Analysis results on townships and villages general statuses showed township health center and village clinic are the major health care facilities in rural poor areas. The number of staff in 36 THCs and 104 VCs were a little lower than the national average. In township health centers, 59. 9% staff are with primary or without any professional titles and 35. 9% of the total staff have no professional degrees. The average gross value of fixed assets per THC is 186000 yuan, among which special equipment values 41000 yuan. Among professional buildings 43. 3% of total area were dangerous. Only one THC can provide emergent service. 47. 2% THCs be able to diagnose and deal with common emergent stomachache. The provision of health services was lower than average level of national rural areas. Frontier Model analysis showed regression coefficients of total outpatient emergency service, total inpatients, average personnel income, number of total staff, number of doctors and technical index were all larger and positive. It meant that these variables would contribute more to the cost-frontier, and their increase would cause the total health cost rising. So increasing health service provision, improving service quality and functions of health facilities may be the best ways to increase efficiency of these facilities. Also the model showed THC inefficiency eu was 1. 68, which means 40% of the cost wasted. Apart from internal and external factors, residents'health care utilization deficiency and inequity is one of major factors causing inefficiency eu.
乡、村基本情况结果表明,农村贫困地区乡卫生院和村卫生室是农民就近就医的主要场所;36所乡卫生院以及104所村卫生室的人员数量,略低于全国同期农村平均水平;在乡卫生院中,初级职称和无职称者的比例占59.9%,无专业学历者占35.9%;平均每院固定资产总值18.6万元,其中专用设备4.1万元,业务用房中危房面积占43.3%;36所卫生院中,具备急救条件的只有1所,能诊断和处理常见急腹症的占47.2%;卫生服务提供量均低于全国农村平均水平;Frontier模型方法显示,总门诊人次、总出院人次、平均人员工资、人员总数、医生数和技术指数等指标的回归系数较大,且均为正数,即这些变量对"前沿"成本的贡献较大,其正向变化均会带来卫生服务总成本的增加,表明增加卫生服务提供量,提高质量以及完善机构服务功能,是提高乡卫生机构效率的有效途径;同时Frontier模型结果显示,卫生院的低效率〓为1.68,经换算即40%的成本处于浪费状态;影响乡卫生院低效率〓的因素有外部和内部的,而需方卫生服务不公平及利用不足是其主要因素之一。

Since most of the studies are based on the Hardy space and the Bergman space of the unit disk, there is still a lack of their properties on the higher dimensional region for the reason that the topological boundary of the higher dimensional region is very complicated and the multi-dimensional complex analysis theory is very whimsical, which make it difficult to be extended.
