Studies showed that the Giemsa-C banding patterns of Ae.tauschii- H.vulgare amphidiploid is much in accord with that of its two parents, and this further proved that the regenerated plants from embryo callus of hybrids between Ae.tauschii and H.vulgare (2n=28) were spontaneously chromosal doubling amphidiploid.

分析表明，节节麦-大麦双二倍体Giemsa--C带核型与两个亲本的带型基本一致，这证明了节节麦-大麦双二倍体的染色体组成。

Studies on sequence changes in the early genomes of interspecific F_1 hybrid and amphidiploid in CucumisIn the present study,extensive genomic changes were detected in newly obtained allotetraploid of Cucumis,namely Cucumis hytivus Chen and Kirkbride,by AFLP analysis using 12 pairs of EcoR-I/Mse-I primers.

In this paper, several methods are put forward, by which axial resolution of scan microscope could be improved. One is that detecting method of ordinary laser feedback is improved, the orthogonal polarized lights split by Wollaston prism are detected separately, comparing to the ordinary feedback, the axial resolution is improved about 2.9 times.

提出并实验研究了几种可以提高激光反馈扫描显微镜轴向分辨率的方法，一种方法是对常规激光反馈实验中的探测技术进行了改进，用渥拉斯顿棱镜把垂直偏振光分开探测，轴向分辨率可以提高约 2 9倍；另一种方法是用双频激光器中产生的偏振态相互垂直的o光和e光作为反馈光代替了传统的单一光的反馈，轴向分辨率被提高了约 2倍；第三种方法是用双频激光器中产生的o光或e光作为反馈光，轴向分辨率可以提高约 2 5倍。

In the second part of of this thesis, we firstly derivate the operation condition of intracavity SHG of dualwavelength laser from the rate equation, and then numerically calculate the relationship between the laser operation parpmeters and the pumping powers. And then we discuss two possible ways to get balancing outputs of the harmonic waves of the two wavelengths. By comparing the two ways, we find that the method by increasing the geometrical factor of 1079. 5nm SHG has the higher efficiency than the method by adding the additional loss of 1079. 5nm basic wave. Besides, the first method is easier to realize in experiment than the second method.

本论文第二部分从速率方程出发，通过求解速率方程的稳态解得到了Nd：YAP腔内倍频双波长激光的连续运转条件，数值计算得到了随泵浦功率变化的激光运转情况；计算、分析了通过增加主波长的倍频耦合几何因子和增加主波长的腔内损耗两种方法获得均衡的双波长倍频输出的运转情况，通过二者的比较，发现增加倍频耦合几何因子的方法比增加损耗的方法效率更高，而且在实验上更易于实现。

Result The results showed that pyrimethanil (1 000×)+ mancozeb (800×) and thiram (700×) were proved to be advantageous to produce more bulblets. The bulb scales treated by thiram (700×) could produce bigger bulblets.

After stints at Rijeka and Livorno, the lad knows this is his big chance to show what he's worth and confirm the good impression he gave in the last two years in Italy and when playing for his national team, after the doubly unlucky experience at Euro 2008 (the injury for him and Croatia being knocked out in such a dramatic fashion by Turkey).

在里耶卡和利沃诺踢球后，这名青年知道这是展示他的价值的最大良机，他要一如既往地表现出过去两个赛季在意大利给人的印象以及他的国家队比赛的神勇，在2008欧锦赛经历了双倍打击后（受伤令他没法代表克罗地亚出战，而他的国家也在八强输给土耳其）。

Look at the climate/energy bill that came out of the House. Its sponsors had to work twice as hard to produce this breakthrough cap-and-trade legislation. Why? Because with basically no G.O.P.

就众议院提出的气候/能源法案而言，为了制定出这一突破性的&总量管制与排放交易&立法草案，起草人付出了双倍的努力。
