This thesis points out three conditions of favorable soil-returning volume,and gets the critical water-content coefficient of bed-irrigating sowing, andthinks that water volume, soil—returning in volume and initial soil water contentcoefficient affects differently the course and the result of infiltration, and revealsthe laws of variations of soil moisture content, and shows the different effect onsoil - wedded states of water volume, depth of seed ditch, soil apparent density,soil-covering depth,initial soil moisture content, width of seed ditch and soil-wedding states, and suggests that the soil-wedding state watering after sevendays is use to evaluate the quality of bed-watering seeding.

The assumption of the variable tendency of slip-line in active zone is made based on the numerical results. Combining the slip-line equations and boundaries, the formula of bearing capacity is deduced which can consider the density of soil. The formula of bearing capacity of strip footing on ponderable soil is also deduced assuming that the slip-line field of ponderable soil is the same with that of weightless soil, which is proved to be an upper-limit solution, as its the same with that deduced by the upper-limit method in Prandtl mechanism.
在数值计算结果的基础上,对有重土地基主动区滑移线变化趋势进行了合理假设,根据边界条件和特征线方程求得了条形基础极限承载力的解析表达式,该表达式可以计算考虑土重度的条形基础的极限承载力;获得了不考虑重度对滑移线场影响时(即有重土在普朗特尔滑移线场下)极限承载力的解析表达式,该表达式与普朗特尔机动场对应的极限承载力上限解的表达式相同,这就从理论上证明了在土重度对滑移线场没有影响这一假定前提下得到的极限承载力是一个上限;(3)利用上限定理求解了极限承载力的最小上限。

The results for rubber seed oil refining were as follows: For the crude solvent-extracted oil, it was first degummed 20 min by 0.04% H3PO4 at 60℃, and neutralized 10 min by 0.15% CaCO_3, then treated with 5% bleaching clay, and refined oil could be obtained. For the machine-squeezed oil, it was first degummed 20 min by 0.04% H3PO4 at 90℃, and neutralized 10 min by 0.15% CaCO3, then treated with 15% bleaching clay, and refined oil could be obtained.

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。

To do this, it would be necessary only to make a little ball of earth that can be accurately weighed ; then we could easily calculate how many times the earth is larger than this little ball; and by so doing, we might tell, at one's fingerends, that if we suppose the little earth-ball to weigh a hundred-weight the whole globe, being so many times larger, must weigh so many hundred-weights.
要做到这一点,仅仅需要制作一个可以精确称出重量的小土球;然后我们可以很容易计算出地球比小土球大多少倍;如此做来,我们就可以掰着手指头说出,如果假定小土球重一百磅,那么地球大它多少倍,则必然重它多少倍。
