In this study, I compared cotyledon development in isocotylous European Gesneriaceae species to Streptocarpus rexii, their sister clade species with true anisocotyly. The results of cotyledon size measurement showed that European Gesneriaceae species exhibit nearly equal cell growth rate and thus maintain both cotyledons in the same size. But in Streptocarpus rexii, growth rate between macrocotyledon and microcotyledon was different thus altered cotyledon allometry growth.

我们藉由比较欧洲苦苣苔成员及仍具备子叶不等大发育的模式物种堇兰间的发育及形态差异，经由子叶面积大小的测量，欧洲苦苣苔成员两片子叶呈现相似的生长速率，因此维持两片子叶等大的特徵，然而堇兰的大小子叶的确具有不同的生长速率，使得堇兰两片子叶异速生长并造成堇兰子叶不等大的特性。

The study's findings indicate: the unconfined compressive strength of red sandstone is mainly lined with compaction rate, pore distribution and condition of being linked with grains and the above factors have a more notable impact on its unconfined compressive strength; grains' area ratio and Euler number decrease as a whole, pores' directionality gradually increases, stability of its internal structure reduces.

研究结果表明：红砂岩的单轴抗压强度主要与密实程度、微孔洞等缺陷的分布情况及颗粒之间的联结状态有关，随着红砂岩风化程度的增强，以上各因素对其单轴抗压强度的影响将更加显著；随荷载的增加，红砂岩的颗粒面积比例及欧拉数总体上趋于减小，孔隙分布分维趋于增大，内部结构的稳定性不断降低。

The findings indicate that under uniaxial compression, the red sandstones at first experience structural intensification and then structural degradation until they are failed; the unconfined compressive strength of red sandstone is mainly related with compaction rate, pore distribution and connecting condition of mineral grains; and the above factors have a more notable impact on the unconfined compressive strength of red sandstone with the increase of weathering; with the increase of load, the grains area ratio and Euler number decrease, the pore develops towards centralization or collectivization, and the red sandstones gradually lose their resistance to deformation.

研究结果表明：在单轴压缩条件下，红砂岩先结构强化，后结构劣化，直至最终破坏；红砂岩的单轴抗压强度主要与密实程度、微孔洞等缺陷的分布情况及矿物颗粒之间的联结状态有关，随着红砂岩风化程度的增强，以上各因素对其单轴抗压强度的影响将更加显著；伴随荷载的增加，红砂岩的矿物颗粒面积比例及欧拉数总体上趋于减小，孔隙向着集中化和集团化的趋势发展，红砂岩抗变形能力逐步丧失。

The results are listed as follows:(1) In peneplain with plenty water-resource, hexagonal spatial structure of urban system can be formed. Due to differential competed function of central places, the hexagonal system is distorted. The result is that the area covered is decr eased and the girth is unchanged——but every border is usually unequal;(2) A pattern of pentagonal system evolves from hexagonal system controlled by a river;(3) A pattern of quadrilateral develops from hexagonal system under two parallel rivers;(4) The equal distance distribution of central places in narrow geographic space has its special reasons. The results are very important for understanding urban's formation and development and urban plan in Huang-Huai-Hai plain.

本文通过自然地理因素中水文、地形这两个重要要素对城镇体系空间结构形成的影响，分析了华北平原区在不同要素影响下的城镇体系空间结构样式：①在水源充足的准"均质"河北冲积平原上，基本满足六边形形成条件，但由于周边中心地发展竞争力不同，故使得正六边形发生畸变——覆盖面积减小而周长却保持不变；②构建了在一条河流影响下的六边形网络结构朝五边形网络演变的模型；③构建了在平行状河流作用下六边形网络向四边形网络演替的模式；④指出了在水源充足的狭长地理空间，城镇体系空间结构发育成等间距的现象与原因。

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。

There has been various large-scale dredgers used for broad rivers, and the technique is already very mature, but producing such a dredger costs more than ten millions. In addition, they can only be applied to large-scale fields. it's incapable for narrower fields, such as pools and ditches in suburbs, the corners of dike and so on.

世界上已有的用于大型江河湖泊清淤的各种不同的挖泥船技术已经相当成熟，但制造这样一艘挖泥船所需成本高达上千万，而且它只能应用于作用面积极大的场合，对于水域狭窄的郊区、农村的沟渠、池塘和溪流以及堤岸死角等处的清淤就爱莫能助了。

In terms of each of these essentials, Lyapunov direct methods, transient energy function methods and extended equal-area criterion are critically compared in this four-part paper. This reveals the essence causes for why both Lyapunov direct methods and TEF methods cannot be applied to transient stability analysis of power systems.
