Taking the administrative villages as units, a comprehensive and detailed survey was made to attain the rich and reliable data, including the information about the status of the land use, the relationship of the land supply and demand, the living standards of farmers and the minimum of urban resident living guarantee and so on. Then the estimating system was established. Afterwards, basing the survey and the system, the character of each unit was transfer into data. And, utilizing the frequency law, the whole county was divided into four expropriation land blocks. The area was measured and the map, showing the differences between blocks, of the Arable Land Blocks for expropriation of Siyang was protracted by the method of GIS. Finally, the land expropriation price is calculated by agricultural land economical function compensate method and urban construction land criterion price avulse method, then the price was tested by expropriation case comparison method. It is beneficial not only for protecting farmers rights and interests, but also for link up with the current land compensate standard, so this way to calculate the land expropriate price is more reasonably.

以行政村为基本单元，对该地区的农用地利用现状、土地供求关系、农民生活水平扣城镇居民最低生活保障水平等情况进行了调查，建立征地区片价格评价体系，根据每个评价单元的综合评价分值，运用总分频率法将全县分为四个区片，并对各级区片进行面积量算，借助地理信息技术绘制了《泗阳县农用地征地区片价格分布图》，显化了农用地征地区片价格的空间分布及其差异，最后运用农用地经济功能价格补偿法和城镇建设用地基准地价剥离法综合测算农用地征地区片价格，并用征地案例比较法的测算结果加以比较验证，证明此测算结果相对更加科学合理，既有利于保障被征地农民的合法权益，又有利于与现行的征地补偿标准相衔接。

The DRe differences among plants could be well differentiated by TP. The DRe., i.e. water retention, represented by TP, was used as a major index to identify the ability of plant drought tolerance. It was showed that C.arborescens Ecotype Wu was generally the most drought tolerant one except lower than C.arborescens Ecotype XJ which was the maximum in May, bore comparison with Zygophyllum xanthoxylum by estimating seasonally; C.latens Ecotype NX was significantlly lower than C.arborescens Ecotype Wu, the result was contrary to being known; C.arborescens Ecotype Kerqin was significantlly lower than Wu; XJ, the maximum in May, showed no else great difference to NX; C.lanata was high in April and not high afterwards, however its phenological phase presented visible changes as compared with the original life patterns in western America.

Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

The polarization curve is not sufficient for a reliable and unique validation of a PEMFC model since different parameters can lead to an identical polarization curve. A three-step validation approach is proposed for a complete and unique validation. These three steps are:(1) validated by the global polarization curve,(2) validated by the local current density distribution curve, and (3) validated by the cathode over-potential and anode over-potential versus current density curve. The results from the comparison of four flow-fields show that the PEMFC performance of the flow-fields decreases in order by interdigitated, metal foam, pin-type and parallel.

通过PEMFC参数敏感性研究发现，PEMFC性能受多种参数的影响，这些参数可分为非敏感性参数、敏感性参数和高敏感性参数；与阳极侧参数相比，PEMFC性能对阴极侧的参数更敏感；不同参数值的组合可以得到几乎完全相同的极化曲线，因此电池的极化曲线不足以用于验证数学模型的唯一性与可靠性；为验证PEMFC数学模型的唯一性与可靠性，提出了模型验证的三步法：极化曲线验证、局部电流密度验证和阳极总过电位与阴极总过电位验证。
