But ECT technology has the following characteristics: 1 the measured capacitance and its change induced by the measured material concentration variation are very small, but the stray capacitances of co-axial screening cable and CMOS switches are relative very large, so the capacitance detecting is easily affected by the stray capacitances, 2 the electric fields in the sensors detecting region is affected by the permittivity distribution, non-uniformity of the space responsive sensitivity is very high, and the image reconstruction is undetermined.

但由于ECT技术中，首先所检测的微电容量及其因物流相含率的变化所引起的变化量很小，而由相关的连接同轴屏蔽电缆与切换CMOS开关所引入的杂散电容远远大于测量电容，微电容的测量容易受杂散电容等的影响；其次，多电极电容传感器测量区内的电场受介质分布的影响，且测量区内的空间响应灵敏度极不均衡，其影响图像重建的不确定性；其三，ECT中的图像重建，由于其是一个欠定问题的求解，在迭代求解方法中，迭代的初值影响迭代过程收敛到近似解的速度；其四，对于气/固两相流应用而言，由于ECT系统在线标定的难以实现，管壁磨损等因素的影响制约该技术应用于生产工艺中气/固两相流的长期连续检测。

Secondly, the construction simulation were performed by the model in ANSYS. The effect were emphasized in the construction process, which induced by temperature, geometric nonlinearity, and boundary condition.

Hence, we first analyzed and studied the kinematics and dynamics of PDC bit, and that are utilized to analyzed how to hame cutters by PDC bit whirlpool. Onthe based of this, we do the cutting experiments. With the test, we not only think over the influence to force actting on cutters in rock nature, drilling parameter, cuttersdensity distributed, and also wear state of cutters and PDC bit appearance. Because the PDC bit's cutters are repeaded by polycrystalline-diamand and tungsten carbide, the specific property of PDC wear are not alike that of polycrystalline-diamand and not alike tungsten carbide.

因此，本文首先分析研究了PDC钻头的运动学和动力学，并利用分析的结果对PDC钻头的涡动是如何损坏切削齿的进行了探讨；在此基础上，进行了PDC钻头切削齿的受力实验，在受力实验研究中，不仅考虑了岩性、钻进参数、布齿密度等对切削齿受力的影响，而且考虑了切削齿不同的磨损状态、钻头的冠部形状对切削齿受力的影响；PDC钻头的切削齿是由聚晶金刚石层和碳化钨底层复合而成的，它的磨损特点既不同于金刚石的磨损又不同于碳化钨的磨损，因此，在分析了复合片磨损机理的基础上，进行了PDC钻头切削齿的磨损实验。

The results showed that in the four rehabilitated forests, the previous month's soil moisture content had stronger effects on the current month's soil moisture content in 0-40 cm and 20-40 cm layers, but had lesser effects on that in 0-10 cm layer. The soil moisture content in 20-40 cm layer was mainly affected by current month's precipitation, while that in 0-10 cm layer was mainly affected by current month's evaporation. The correlation coefficient between current month's precipitation and soil moisture content was the largest in pure Liquidambar formosana plantation, and the auto-interrelation coefficient of soil moisture content was larger in mixed forests than in pure L. formosana plantation.

结果表明：研究区各重建森林前一个月的土壤含水量对当月整个土壤剖面(0~40 cm)平均土壤含水量和当月20~40 cm土层土壤含水量具有较强影响，对当月0~10 cm土层土壤含水量的影响较小；研究区各重建森林20~40 cm土层土壤含水量主要受当月降水量的影响，0~10 cm土层土壤含水量主要受当月蒸发量的影响；在4种森林重建模式中，枫香纯林当月降水量与当月土壤含水量的相关系数最大，混交林模式土壤含水量的自相关系数大于纯林模式。

Data for the study were collected by field survey and collection of second-hand material.The main conclusions of the study include: 1 the transfer of collective forest land and stumpage will determine to what extent the aims of the current institutional reform will be achieved; 2 at present the transfer is highly affected by the transfer institution, while the requirement of transaction in the market is not suited to farmers; 3 farmers earn money from the transfer, while they do not benefit reasonably from the transfer; 4 farmers'economic activities are not completely rational, and their economic behaviors are affected by cognitive degree on the institution, non-agricultural production activities, investment in forestry, and family status; 5 there are large variations among those who take over different forest lands and stumpages, however they all try to maximize their owns profits; and 6 policy regulation plays negative influence on the development of transaction market.

本研究结论如下：第一，集体林地林木流转的开展情况对于集体林权制度改革目标实现的影响重大；第二，集体林地林木流转现状反映了现行流转制度安排；第三，农户通过流转得以增收，但流转收益并不完全具有合理性；第四，农户转出林地林木行为受制度认知程度、非农生产活动、林业生产投入和家庭状况等多层面因素影响；第五，受制度约束影响，受让方流转行呈现差异性；第六，政策规制的存在，影响了流转市场发育。

Type-B Nodule: The source of elements in the nodules comes from slow deposition of the overlying water and the diffusion of the pore water, which comes mainly from the double decomposition reaction of Fe, Mn oxides caused by the oxidation diagenesis of organic material in sediment and its forming process and distribution is controlled by pH in the pore water. There is no corrlation between distribution of the nodules and water depth, topograph.

A型结核主要分布于深海火山沉积环境区，受上覆水Mn〓和Eh制约；B型结核一方面由于在深海火山沉积环境区，受生物作用影响，另一方面在生物沉积环境区，又受火山作用影响，使此类结核的分布与大洋地貌和沉积物的关系不明显；C型结核主要分布在太平洋CCD范围内，受沉积环境上生物和活性有机碳的制约。

Result shown: value of fractal dimension is a comprehensive index, which reflect the changes of landscape, patch areas, patch numbers, area per patch, and their interaction. And the index can reflect the irregular degree and the complex degree of landscape patch in dumping place. The fractal dimension of mixed vegetation of arbors – shrubs and mixed vegetation of shrubs maintain the high level, while fractal dimension of new reclamation land and grass land are low. The difference of other type landscape fractal dimension is not significant. Vegetation landscape is influenced by many kinds of factors. It is primarily influenced by surface material composition and terrain in south and west dumping place, which diversity index is high. It is primarily influenced by vegetation type in inner dumping place and expanded west dumping place. The landscape multiplicity index of the mixed vegetation of grass and shrubs is higher than other landscape type, but landscape dominance index of this area maintains on the lower level.

结果表明：分维数的大小反映了景观斑块面积、斑块数量和平均斑块面积等因素的相互作用，反映了排土场内景观斑块的不规则程度和复杂程度；乔灌混交地和灌木混交地保持着较高的分维数，新造复垦地和草地的分维数较低，其它景观类型的分维数则差别不大；植被景观受多种因子的影响，在南排土场、西排土场受地表物质组成和地形的影响为主，其多样性指数较高，在内排土场、西排扩大区受植被类型的影响为主；草灌混交地的景观多样性远高于其它现有的复垦植被区，但其景观优势度则保持在较低水平上。

DI is the most ideal irrigation indicator as it is very much influenced by soil water potential and less affected by meteorological factors. DI value of zero is probably the best irrigation threshold. MDS is strongly affected by meteorological factors and requires reference MDS under well-irrigated conditions. RT on the other hand is not significantly related with soil water potential. Therefore neither of these variables is suitable as irrigation index.

DI 受土壤水势影响产生变化的趋势明显并受气象因子影响较小，是最理想的灌溉控制指标，可将 DI =0作为灌溉控制临界值； MDS 受气象因子影响强烈，变异性较大，且需要充分灌溉条件下的 DI 作为参考， RT 与土壤水势的相关性不高，因此均不适合单独作为灌溉控制指标。
