这一结果与以往类似研究中多数研究者得到的结论存在本质区别，原因可能在于此次试验的试验条件与以往研究的试验条件不同，其中最主要一点是在本次试验中使用的土壤样品的重量比以往试验均显著增大，而且使用的是土壤结构和组成等均未经破坏的原位土，从而使入渗酸雨与承受酸雨沉降的土壤之间的比例关系更接近自然酸雨沉降过程，以此为基础得到的试验结果应该更加客观、可靠。2、酸雨对盐基离子活化迁移产生的影响勿庸置疑，但是，在盐基离子活化迁移的过程中，并没有出现预想中的重金属元素活化迁移现象，表明土壤中的重金属元素并不如理论分析的那样对酸雨沉降反应敏感。

JMC1402P标记菌株释放环境的安全性研究表明，当JMC1402P与华癸中生根瘤菌JS5A16L、荧光假单胞菌Pf.X16L_2混合培养在微孔滤膜上、灭菌盆装土及田间三个环境中时，未检测到华癸中生根瘤菌JS5A16L和荧光假单胞菌Pf.X16L_2中有gfp基因编码的绿色荧光蛋白的存在，在X-GlucA作用下亦没有带有gusA基因的发光菌落。

In China,more and more constructions in cold regions appear,Strength and deformationof frozen soil,characteristics of frost heave and thaw collapse have become the major task forcold regional construction.But researches on mechanism of frost heaving are still not maturedowing to complexity of frozen soil,and the current study,thinking little of the freezing andthawing process,mostly focuses on the different physical and mechanical properties betweenfrozen soil and thawed soil.

随着我国寒区工程建设项目的增多，冻土的强度与变形问题以及冻胀融沉特性研究成为面临的最重要任务，但是由于冻土的复杂性，现有的冻胀机理相关研究尚不成熟，大多还是研究已冻土和融土物理力学性质差别，缺乏对正冻正融过程的相关研究。

The key of maintaining the tunnel stability lies on how to deal with the advance core soil ahead of working face, which is obtained on basis of analysis on the problems in high speed railway tunnels with big crosssections in soft surrounding rock or soil. Fullface prereinforcing method by fiberglass bolts can enhance the equivalent rigidity of the advance core soil and control the deformation of the advance core soil, so that arch effect can play its role naturally and assure the excavation safety.

总结分析了目前高速铁路大断面软弱围岩或土质隧道施工中存在的问题，认为如何处理好掌子面前方的"待挖核心体"是控制此类隧道整体稳定性的关键，运用沿隧道纵向全断面预加固的易切削玻璃纤维锚杆来提高"待挖核心体"的等效刚度，控制"待挖核心体"的变形，使得隧道周边的拱效应能自然发挥作用，可以保证隧道能够全断面安全、顺利开挖掘进。

The result also showed that return treatment is better than taken treatment within different treatments. 4. According to the experiment when the plant was harvested(In March 25th,2009), it was found that the rape with NPK treatment,especially with NPK-T treatment in Quaternary red soil and in granitization red soil, grew abnormality or dead in the centre of district(80%),which yield was extremely low,but had some to the remaining(20%) close to the cement ridge.Among the three types of parent material,eighteen districts,Dischaemum Schreb of gramineae plants could only grow in granitization red soil with NPK treatment,and the other sixteen districts were little or even not.The rape planted in Quaternary red soil with NPK treatment got disease especially in the centre of the district.

其次是M处理，CK最低。3、三种母质种植油菜均表现为：归还处理好于带走处理；4、据试验收产时（2009年3月25日）发现：四纪红土和花岗岩二种母质的NPK处理的油菜除靠近水泥梗边行长有部分油菜外（占小区面积20%），小区中间（占小区面积80%）的油菜生长不正常或死亡，产量极低；三种母质共18个小区，只有花岗岩母质的NPK处理长有禾本科植物马唐草，其余16个小区很少或没有；四纪红土NPK处理油菜病害严重。

Due to an abundant rainfall and frequent rainstorm, and geographical characteristics of mountain and hills, the potential erosive dynamics of soil erosion is strong. The low resistant erosion ability of ground substance, especially in granite weathering crust and purple rock and its soil are the inner causes of severe soil erosion. The utilization of natural resource of mankind was increased due to characteristics of social and economic environment of the province. The unreasonable land utilization caused vegetation destroy, which is the key factor of soil erosion.

丰沛的降雨和频繁的暴雨，以及多山地丘陵的地形特征，为土壤侵蚀提供了强大的侵蚀潜在动力；抗侵蚀性较弱的地面组成物质，特别是花岗岩和紫色岩风化壳及其土壤，是造成土壤侵蚀特别严重的内在原因；而社会经济环境特点使人类利用自然资源强度增加，出现了一系列土地利用不合理现象，导致其中植被破坏，是造成土壤侵蚀的决定性因子。
