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.
浙江大学硕士毕业论文浙北海涂土壤水分特性及溶质运移模拟研究 4、海涂土壤的导水能力强,且土壤剖面备土层的饱和导水率变化大,原状土的饱和导水率远大于扰动土的饱和导水率,围垦时间较早的海涂土壤的饱和导水率较围垦时间晚的海涂土壤的饱和导水率要小;不同含水量下的非饱和导水率变化范围很大,最大值与最小值差距可达 10'③ 5、容重的不同对入渗率、扩散率、非饱和导水率都有影响,容重小,入渗率、扩散率、非饱和导水率也花 6、在海涂土壤中运移的氯离子是一&惰性离子&,氯离子在土壤运移过程中的分布有一定的确定性和重现性,与入渗时间和入渗速度无关,溶质运移过程中,入渗溶液的浓度和海涂土壤的质地对溶质运移综合扩散系数DSh无明显影响,而土壤容重对溶质运移综合扩散系数DSh有影响,容重小,DSh大。

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。

Microscopic characteristics of cladded crystal fiber are analyzed by X-ray diffraction, Laue X-ray diffraction and scanning electron microscopy, it is found that magnesium-ion indiffusion does not affect the single crystal structure and the domain structure of the magnesium diffused crystal fiber. It is found for the first time that MgO-rich layer in the magnesium diffused LiNbO〓 surface layer exhibits the crystal structure of an unknown compound from the Li-Mg-Nb-O ternary system and MgNb〓O〓. It is proposed for the first time that this unknown compound and MgNb〓O〓 in MgO-rich layer are the real sources of magnesium-ion indiffusion LiNbO〓. Their appearance indicate that MgNb〓O〓 is in the surface layer of MgO-rich layer, the unknown compound is in the subsurface layer and beneath where the MgNb〓O〓 is located, and these compounds have obviously preferred orientation.
