结果表明，与去离子水CK相比，pH3.5和pH4.5模拟酸雨淋洗后0~10cm土层pH分别降低了0.27、0.44和0.08、0.18个单位，土壤交换性Al含量分别增加了4.43%和2.38%；而10~50cm土层pH没有显著变化。

Desc-depth The depth of characters with descenders, such as p,q, or y.

No evident regularity was found in the depth from 15 to 30 cm. There was an obvious accumulation of OM and TN in the top 30 cm of the fallowed soils, of which the accumulation of OM was faster than that of TN and there was more accumulation in no-tillage compared to tillage. Soils applied with inorganic and organic fertilizers had much more OM and TN at 0～5 cm and 5～15 cm depth than soils applied with only inorganic fertilizers and soils without fertilization. However, OM and TN in these treatments were less than that in fallow treatment. No significant differences in OM and TN contents were found between fertilization treatments. Only in the 5 cm of top soils, OM and TN of the soils treated with only inorganic fertilizers were more than that of CK.

长期休闲的土壤在整个耕层有明显的有机质和氮素累积，其中碳的累积快于氮的累积，免耕条件下比耕翻条件下累积量更大。0～5 cm和5～15 cm土层有机肥与无机肥配施的处理，其有机质和全氮质量分数均显著高于单施化肥处理和不施肥处理，但均低于休闲处理；15～30 cm土层各培肥处理则无明显差异；单施化肥的土壤有机质和全氮质量分数高于不施肥处理，但这种差异只在表层（0～5 cm）较显著。

The article analyses the relationship between the load of pile in the direction and the pile root.The investigation indicates that the carrying capacity has nice adaptability to the soil floor depth the column knocked into and change of the oil floor construction when the plinth depth is larger than 60cm,and the length of the column and the change of the soil floor have little impact on load of pile,whereas load of pile is more sensitive to the anti-sinking and change of column diameter dimension.

分析了基桩竖向承载力与桩体结构的关系，研究表明：承载力在基桩深度大于60cm后对桩体打入土层深度、土层结构变化有良好的适应性，桩长和土层结构的变化对基桩承载力的影响不大，而基桩承载力对止沉盘和桩径尺寸变化敏感。

The results showed that dynamic cutting force F varied much compared with dynamic cutting force F and F. Dynamic cutting force increased with feed and depth of cut, especially when depth of cut was 0.1 mm.

动态切削力随进给量和切削深度的增加而增加，其中在切削深度为0.1 mm的情况下，切削力出现了较大的波动。

This paper presents a rapid inversion method for 3D apparent density based on separation and continuation of potential field. The new method is carried out in the following three steps. Firstly, the gravity field on the plane is separated by a cutting method into several parts corresponding to strata of different depth. Secondly, by the way of downward continuation, the field resulted from different strata is respectively reduced to a plane corresponding to its depth.

文中提出了一种基于位场分离与延拓的视密度快速反演方法：首先应用场分离的切割法对平面上的重力场进行不同深度层源的切割分离；然后运用大深度向下延拓方法将各层的场延拓至相应的深度；最后反演出各深度层的密度。

According to measured data of ground temperature along QXH, the relationships among thermal thaw-erosion sensibility, freezing-thawing process, seasonally thawing depth and permafrost ground temperature, among permafrost temperature, mean annual ground temperature and seasonally thaw depth and among surface landscape stability, freezing-thawing hazards and their forming possibility are systemically analyzed.
