高频率

Microseismic events are characterized by high frequency,short duration,and weak energy.They may even be smeared by random noises.

The results of the simulation showed that the GMI ratio for a sandwich structured film sandwiching high conductive metal layer was several times lager than that for a monofilm, and the maximum impedance change ratio occurred at the frequency of about 10 MHz which was lower than that of single layer film.

模拟的结果表明，中间夹高导电性材料的F/M/F型三明治薄膜的巨磁阻抗效应比同样厚度的单层磁性薄膜的巨磁阻抗效应要大很多，而且三明治薄膜出现阻抗最大变化时的频率大概在10MHz左右，比单层薄膜要低得多。

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。

Raw meat in Kunming market has to undergo a rigorous inspection and management. Serving soup temperature is higher than the hygiene supervision and inspection standards. The operation accuracy of the consumers is related to gender, occupation, eating frequency and parasitological knowledge level. When the temperature of the serving soup is not high enough, actions of consumers are different.

昆明市场上的生肉受到严格检验检疫和多重监督管理；汤温达到卫生监督标准；顾客的科学操作比例与性别、职业、食用频率和寄生虫学知识程度有关；顾客遇到汤温不够高时的处理方式与性别、职业和对汤温的担心程度有关。

The advantages chiefly consist of below respects: The effect time is long ;The effect extent is vast ;The demonstration behavior that the mass media supplied is more infective ; The means of effect is more diversified ;Audience learns more willingly; the mass media affect audience behavior more permeably. The information of the mass media changed quickly, it reflected the specific of the age, and this kind of feature is very helpful for audience to learn new behavior and to adapt the society, which develops fast.

这种优势体现在以下几方面：影响时间长；影响范围广；大众媒介提供的示范行为更具感染性；影响的方式更加多样；受众在大众媒介的影响下，学习更具自觉性；大众媒介影响受众行为的渗透性；大众媒介信息传播速度快，更新频率高，反映时代特色，这对于受众快速地学习新的行为模式以适应飞速发展的社会是十分重要的。
