When the geometric similitude ratio of the model to the prototype was determined and the loading similitude condition was satisfied by using similitude theory in structure modeling and experimental techniques, the prototype soil parameters were derived according to the model test result. The vibrating wheel compelled by harmonic exciting force was treated as a lumped mass vibrating system by equation equity method. By using this mechanical model in vibrating compaction, soil parameters were identified according to the equivalence of vibrating differential equation. The curve fitting method of amplitude versus frequency response was used for dynamic simulation based on the systematic dynamic equation of vibrating roller-soil system.

The uncertainty about the ultimate technical feasibility of reanimation may very well be dwarfed by the uncertainty in other factors, such as the possibility that you deanimate in the wrong kind of way (by being lost at sea, for example, or by having the brain's information content erased by Alzheimer's disease), that your cryonics company goes bust, that civilization collapses, or that people in the future won't be interested in reviving you.

复苏的最终技术可行的不确定性与其他不确定性因素相比，几乎可以忽略不计。比如，你的生命流失在一个错误的地方（像失踪在海上或大脑的信息内容被阿尔茨·海默氏病删除），你的冷冻复苏公司破产，文明崩溃，或者未来的人们没有兴趣恢复你。

Assulta and the induction of GST activity by nicotine and capsicine in H. assulta provided partial supports for the hypothesis that diet breadth was governed by detoxification abilities. The results also indicated that two sibling species had different strategies of adaptation to toxic substances: H. assulta saves expenditure of nutrients and energy by restricting their countermeasures to a few potentially toxic compounds. H. armigera, by contrast, must be prepared to counter a wider range of potential toxins. 5. Compared with parental species, hybrids of reciprocal hybridization had significant difference in feeding preference for hot pepper.

结果显示，广食性的棉铃虫在中肠羧酸酯酶和谷胱甘肽-S-转移酶活性方面高于寡食性的烟青虫，但烟青虫谷胱甘肽-S-转移酶活性可以被寄主植物内的烟碱和辣椒素所诱导，表明解毒酶活性在一定程度上影响着植食性昆虫的食性广度；同时也暗示着二近缘种对有毒的次生物质采取不同的适应策略：烟青虫有选择地对付种类较少的植物次生物质以减轻营养和能量的消耗；棉铃虫则必须对付存在于其寄主植物内的种类繁多的有毒次生物质。

By using testing functions to make comparative research on the precision of approximate models which were built by RBF under the condition of different sample amounts and different kernel function types, a conclusion was drawn: the model quality built by Reciprocal Multiquadric RBF as kernel function was highest when the sample amout was big, and the model quality built by Gaussian RBF as kernel function was highest when the sample amount was small.
