中值

The detailed coefficients of DWT contain signal and noise. Instead of the soft-thresholding method, SVD is applied to decompose the signal features and noise into different orthogonal subspaces. With the reconstruction of the singular vectors in subspace, the signal features are extracted effectively.

该方法通过对每层小波分解细节系数进行奇异值分解，将其中的信号特征成分和噪声分解到不同的正交子空间中，在子空间中选取集成信号特征成分的奇异值矢量进行重构，从而提取出淹没在细节系数中的有用信号成分，最后进行小波重建，得到降噪信号。

The result show, pH of solution, the type and concentration of surface-active agent all have marked effect, pH change can transform the disperse behavior of attapulgite particle by altering granularity distributing in different range, influencing double electromotive force between particle and solution.

研究表明，水溶液的pH值、表面活性剂的类型和浓度对凹土的分散稳定性皆有显著的影响，pH值的变化改变了不同粒径范围的粒子总量分布，改变粒子与溶液间双电层电动势，从而改变凹土粒子的分散行为：由于凹土作为带电粒子在极性溶剂中容易达到物理分散的目的，因此，凹土在极性溶剂中的分散状况大大优于在非极性溶剂中的分散。

In better management lawn community Geranium sibiricum, Potentilla anserine and Leymus secalinus are the dominant weeds all the time and Geranium sibiricum is the most dominant weed.The regular pattern of Shannon-Weinor index of turf weeds in three different management lawn communities is that in worse community maximum Shannon-Weinor index appears in spring and fall but in better community is in late-summer and primary-fall.

The results showed that the critical values of Cd,Pb,and Cu in the Juncus Effuses grown soil were set at 10,100 and 100mg kg-1 respectively,but Juncus Effuses was not able to grow in the Zn polluted soil.

结果表明：种植灯心草土壤中的Cd、Pb、Cu三种重金属临界值可分别设定为10mg kg-1、100 mg kg-1、100mg kg-1。灯心草不适合在Zn污染的土壤中种植，土壤中As临界值尚需作进一步的研究来确定。

Moreover, the actual allele frequency of most varieties deviates far from Hardy-Weinberg equilibrium. All PPB、na 、I、h、Gi and Fst have proved to be the references to elucidate that ISSR is a most powerful tool to analyze genetic diversity, compared with the RAPD marker and the allozyme marker is less strong ordinally. We could divided the 70 samples into A, B, C, D and E five groups using three methods according to genetic distance clustering. There is a bit displacement for few varieties in different clustering maps, but the most are similar to morphological analysis despite that there is still a great difference among cultivars in the same one group. The above results imply that the three methods have the different sensitivity and resolution in genetic distance analysis of close varieties. The Mantel test indicates that the results from the three kinds of markers have the significant correlation, which demonstrates that the number of the used three kinds of markers is enough to exactly detect the diversity of all 70 samples to ideal extent. And these methods can be used to evaluate the diversity of the whole group using the miscellaneous samples instead of the individual sample, of the Gerbera jamesonii are mainly from tissue culture plants. In conclusion, the above study results provide a reference for the application of three kinds of molecular markers to molecular marker-assisted breeding of flower. 2. The genetic diversity among the eight introduced cut-flower varieties of Ranunculus asiatica was analyzed by the ISSR markers. Based on the genetic clustering tree, all the colorful flower varieties are clustered into one group, and the white flower varieties into another group. Moreover, among the former group the yellow flower varieties are clustered into one sub-group, and the reddish flower varieties, such as rose color, pink, nacarat, are clusetered into another sub-group.

由三种分子标记的分析结果可以看出，等位基因平均值、观察杂合度、Fis值、Fit值皆较高，表明非洲菊等位基因较丰富，杂合基因偏多，且绝大部份品种的实际等位基因频率在品种内偏离了Hardy-Weinberg equilibrium；PP8、na、Ⅰ、h、Gi及Fst皆表明，ISSR检测遗传多样性的能力最强，其次是RAPD，等位酶最低；根据遗传距离进行聚类，三种方法都把70个品种分成A、B、C、D、E五个大组，每一组中除少数品种发生位移外，大部份品种分类结果相似，且与形态分析结果有相似性，但在每一组中，品种间的聚类差别较大，表明这三种方法在近距离品种间检测遗传变异时灵敏度及分辨力不同；Mantel检测表明，三种标记的分析结果有显著相关性，表明所用的三种分子方法的标记数量已经可以相对无偏地检测到70个品种间遗传变异；非洲菊为组培苗，三种标记的检测结果皆表明，混合样品可以作为个体样品的代表，对整个居群的遗传多样性进行评价；这些研究结果可为三种分子标记方法在花卉分子辅助育种中的进一步应用提供借鉴。

Basing on my own experimental results and that of theSLA researcher (Takayuki Nakamori 2001), I come to this tentative conclusion: UGPrinciples are accessible to all L2 learners, no matter whether the principles are instantiatedin the L1 or not; with respect to the parameters, the parametric values instantiated in the L1are initially available; while the two languages differ in parameter settings, someparameters can be resettable but to some other parameters, such as the Spec-parameter that isassociated with functional categories, become difficult even closed to the resetting; otherwiseevery L2 learner can acquire the target language successfully as well as the native speakerdoes.

根据自己的实验结果及第二语言研究者(Takayuki Nakamori 2001)的实验结果得出了这样一个结论：普遍语法中的原则对所有的第二语言习得者来说仍然可及，不管这些原则是否体现在第一语言中；但在参数方面，体现在第一语言里的参数值在第二语言习得中是可以首先习得的，但当第一语言和第二语言的参数值不同时，某些参数可以重新设定而对某些参数例如与功能管辖范围相关的具体参数就很难甚至不能重新设定；否则每一个第二语言习得者都能像母语习得者习得母语那样成功地习得目标语。

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.

On the other hand, as illustrated in Picture B and D, the price drop would become material objects' price drop because of the continuous flow syphonage capital. Pictures stood by Picture B and D can become anti-syphonage theory pictures. The syphonage pictures and anti-syphonage pictures can simply stand for two converse investment opportunities. Under normal situations, commodity's syphonage capital flow can demonstrate a slow increasing situation in the long run. But the situation is usually affected by supply-and-demand situation in the middle and short run. Especially in the type of gurantee sum exchange, the supply-and-demand situation is a major factor affecting commodity price even in a price dominated market. The commodity's ultimate price will comparatively alter when the outer influence changes, and sometimes the price may change to a completely converse direction as expected. In case of the above case, we need to observe and research the influential factors. However the research is not like the Butterfly Theory research on slight variables. Syphonage theory deems that if continuous observance extends more than a certain percentage, such as 10% influential factor, and we continue researching, immediately putting 10% influential factors into research scale, we could finish the all-round research on commodity price analysis.

其中，图A和C表示的图形我们成为正向虹吸图形，B和D代表的图形成为反向虹吸理论图形，这种正向虹吸图形和反向虹吸图形分别可以简单代表两种相反的投机机会，在正常情况下，商品的这种虹吸资金流从远期看会表现出缓慢的上升走势，但在中短期，走势经常受到供求关系影响，特别在保证金交易的品种中，即使是价格操纵的市场中，供求关系也是影响商品价格的主要因素，这种以供求关系为主导的市场中，虹吸终值并不是一成不变的，在外在影响因素发生变化时，商品终值也会相应变化，有时甚至会改变到和预期截然相反的方向，这就需要我们经常对相关影响因素进行跟踪和研究，这种研究并不象蝴蝶理论分析的微小变动因素，虹吸理论认为只要连续跟踪超过一定权重，比如10％影响权重的因素，并持续研究，及时将超过10％影响因素事件纳入调查范围，既可完成对商品价格分析的全面性探索。
