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.

用相似理论与模型试验法在确定了模型与原型之间的几何相似比并满足载荷相似条件后，根据模型试验结果推导出了原型土体参数；用方程对等法把受简谐激振力作用的振动轮等效为集中质量振动系统，以此作为振动压实过程的力学模型，根据振动微分方程的等效条件进行识别；用幅频特性曲线拟合法以振动压路机－土壤系统动力学方程为基础，用计算机进行动态仿真。

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.

运用测试函数对在不同样本数量与不同核函数形式下所建立的近似模型的精度进行对比研究，得出逆多二次函数与高斯函数作为核函数分别在大样本和小样本情况下精度最高的结论，并验证了径向基函数近似模型方法能够兼顾效率与精度。

Many steps were reached using the long-cherished method of Proof by Induction, others by Proof by Reductio ad Absurdum, and still others using Proof by Graduate Student.

许多步骤是用各种经典的逻辑证明方法推导得到的，包括归纳法、反证法等，甚至有些部分还是由旁听的研究生证明的。

A map was achieved in detail for the optimal placement of ablation electrode. According to assumption of complete destruction of tumor and its 0.5 cm margin by 5.0 cm ablation device with this method, calculating results were obtained as follows: a tumor of 4.1 ～ 4.3 cm in diameter required 4 ablation at least by the regular tetrahedron way, a tumor of 4.4 ～ 5.6 cm in diameter required 5～8 ablation at least by the regular prism way, a tumor of 5.7 ～ 6.0 cm required 12 ablation at least by the three layers overlapping way.

根据RFA治疗原则消融范围须超越肿瘤周边 0 。5cm以上；按照覆盖类球体肿瘤的计算结果，采用伞径 5 。0cm的射频针，治疗 4.1～ 4.3cm的肿瘤须用正四面体法至少布针 4个点，治疗 4.4～5 。6cm的肿瘤用正棱柱法至少布针 5～ 8个点，治疗 5 。7～ 6 。0cm的肿瘤用三层重叠法至少布针 12个点，方能达到较彻底覆盖灭活肿瘤的效果。
