It abandon the traditional measure that divide the development course of the scientific and technological park according to the time, and redistrict their development courses according to the logic route that the park grew up, then divide development course into three stages: embryonic stage, it introduce domestic and international agricultural new and high technology , advanced equipment directly, engaged in running an enterprise on a commercial way, use the new and high technology to carry on precise, deep processing or storing and keeping fresh to the high-quality agricultural and animal products, do not have cooperation with local peasant basically; the stage of growing up, the park brings along local peasants production, does not confine to the production of the industrial base in the park again, a kind of nonstandard cooperative form has appeared between peasant and park; at ripe stage, the park sets up the training center of agricultural science and technology, carry on the professional technical training to the industrial base and peripheral peasant, spread through three kinds of diffusion effects, such as radiation, the grade

摒弃了按时间划分科技园区发展历程的传统作法，按照园区成长的逻辑路线对其发展历程进行了重新划分，将发展历程分为三个阶段：萌芽阶段，园区内直接引进国内外农业高新技术、先进设备，从事企业化生产，运用高新技术对优质农畜产品进行精、深加工或储藏保鲜，与当地农户基本上没有合作关系；成长阶段，园区带动当地农产生产，不再局限于园区內产业基地的生产，农产与园区之间出现了一种不规范的合作形式；成熟阶段，园区建立农业科技培训中心，对产业基地及周边农产进行专业技术培训，通过辐射扩散、等级扩散、跳跃扩散三种扩散效应，把经济动力和创新成果传导给周围地区，园区进入规范化管理阶段。

The first the relation of AD model and the energy variety of image is educed by thermal diffusion and the diffusion equations based energy flux, and proves the image processing by energy flux sufficing maximum-minimum principle, the variety of image energy is equivalent to that of image intensity.

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.

It implies that the diffusive atoms teaseling along a dislocation pipe may diffuse outward into the bulk material for diffusion and may again diffuse into another dislocation pipe to continue this sequence of diffusion processes, showing a complex diffusion course.

它意味着，这时在一个位错管内运动的扩散原子，可以离开位错管渗透到晶体中继续扩散，还可以又回到另一个位错管中作扩散运动，从而表现出一个复杂的扩散过程。

The simulation results show that calculated tortuosities varies with network connectivity as well as the Thiele modulus.This work also suggests that tortuosities obtained under diffusion-only conditions can only be used under the strong reaction control conditions.

模拟结果表明，计算出的曲折因子既是孔网络配位数的函数，又随Thiele模数的变化而不同，在纯扩散条件下测得的有效扩散系数只能应用于扩散影响不严重的反应扩散区域。

This thesis is divided into five chapters:Chapter one is the industrialization of the region "externally driven" and the diffusions of the manufacturing industry. It discusses on regional economic development in two ways -"endogenous development" and "externally driven", descripts and sum up China's southeastern coastal areas to undertake international spread of the historical process of industrialization, and analysis its conditions to be the first to accept the of industry diffusion.

我们首先计算了氧原子从稳定的表面面心立方位置向表面六角密排位置的扩散，其扩散激活能为0.77eV；然后计算了氧原子从稳定的SFCC位置扩散到表面下第1层与第2层之间的八面体间隙Octa(1，2)位置，然后继续向表面下第2层与第3层之间的八面体间隙Octa(2，3)位置扩散，在此过程中氧原子需克服2个能垒，其激活能分别为2.14eV和2.57eV。

The results show that: 1 supplementation of protein to maturation media improves cumulus expansion in vitro compared to the protein-free control, but cumulus expansion is not necessarily related to oocyte nuclear maturation in pigs, and cumulus expansion is not the criterae for determination of nuclear maturation of pig oocytes, but only the exclusion of the first polar body; 2 exposure of pig COCs to hormone supplements for 23-24 hours improved cumulus expansion but had no significant effect on nuclear maturation compared to that for 46-48 hours; 3 under our research conditions, supplementation of different proteins into different maturation media has different effects on porcine oocyte nuclear maturation, but has no significant effect on subsequent embryonic development after IVF; 4 the nuclear maturation rates of pig oocytes matured in mTCM+pFF and mNCSU+pFF are superior than that in mNCSU+FCS; 5 different maturation media have no effect on pig oocyte cumulus expansion and subsequent embryonic development after IVF.

结果显示：(1)在成熟液中添加蛋白质可以加强卵丘细胞的扩散，但猪卵母细胞的核成熟与其周围的卵丘细胞扩展没有必然的联系，卵丘细胞扩散或成放射状不宜作为猪卵母细胞核成熟的标准，只有排出第一极体才能作为猪卵母细胞核成熟的标志；(2)在猪COCs的46-48小时成熟培养的后23-24小时阶段去除成熟液中的激素不但可以保证卵母细胞的核成熟率，而且可加强卵丘细胞的扩散；(3)在现有实验条件下，在mTCM和mNCSU中添加10％pFF与在mNCSU中添加10％FCS相比可获得较高的猪卵母细胞核成熟率；(4)在不同的成熟液中添加不同的蛋白质对猪卵母细胞核成熟率的影响效果不一样，但对体外受精后的早期胚胎发育影响不明显；(5)成熟液种类对猪卵母细胞的卵丘细胞扩散和体外受精后的早期胚胎发育无显著影响。
