To be the leader of the saving cause. Although we do not contribute to the country too much, we can turn off the lights and the fans before leaving our classroom, we can reject the one-off chopsticks. Lunch boxes can be used to contain food instead of plastic bags. Use the notebooks which have been used a half and drink the rest water in the bottle . Turn off the running water tap and the working watering trough in time ...... wasting of energy is not far away from us, but saving is so close to all of us.
虽然我们暂时不能为国家贡献很多,但可以在离开教室时顺手关灯,关电扇,可以拒绝使用一次性筷子,可以用饭盒代替塑料袋来盛装食物,用完才用了一半的作业本,喝完瓶里的矿泉水;虽然我们暂时不具备开办节能企业的条件,但我们可以及时关掉还在滴水的龙头,可以及时关闭午休时还在工作的饮水器……能源的浪费离我们不远,节约也近在咫尺!

To study the influence of this damper configuration to aeromechanical stability, some work has been done in this thesis. First, dynamic equation of the rotor-hub system was modeled with the generalized Hamilton principle, which can be used to analyze the stability problem in different conditions like on-ground, hovering and flight. When fastening the fuselage, the model can also be used to analyze the stability problem of isolated rotor system.

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。

The big advantage of the Jackknife is that they can be used to evaluate the statistical properties of a statistic that is related to the data in a complicated, nonanalytical way. Apart from estimation of standard deviation, Jackknife can be used to estimate mean, median and even to construct confidence intervals.
大折刀法的最大优点是它能在一个统计量与资料的关系很复杂或无解析的表达式时,可用它估计统计量的统计特性,除了能得到标准偏差外,还可用来估计平均值和中值,甚至构造置信区间。

The results showed that: the explants of strawberry leaves were rather sensitive to kanamycin, and the corresponding concentration of 20 mg/L could substantially inhibit the growth of non-transformed tisse and be used to screen the leaves of strawberry after transformation. Timentin at the concentration of 300 mg/L could be used to eliminate Agrobacterium tumefaciens and had minor impact on the growth of the explants. The preculture time of 2-4 days was beneficial to improve transformation frequency. Co-culture for 2-3 days not only had higher gus transient expression but also avoid the over-growth of agrobacterium. The bacterial concentration of OD(subscript 600nm) 0.4 was the best inoculum density and 10 minutes was the best inoculation time.
结果表明:草毒叶片外植体对卡那霉素较为敏感,适宜的筛选浓度为20mg/L,可明显抑制非转化组织的生长;300mg/L的羧吩青霉素可有效抑菌,对外植体生长影响也较小;预培养2-4d有利于转化;共培养2-3d有利于提高转化频率并避免了农杆菌的过度生长;OD(下标 600nm)值为0.4的菌液侵染10min效果最佳。
