Taking self-fruitful rate as the criterion and segregating population of field survey as method, we got the result that the ratio of fertile plants and sterile plants in the three F2 population of K-cytoplasmic male sterile hybrid accords with 63:1 tested by Chi-square, therefore we can infer that the restorative mechanism of K-cytoplasmic male sterile line was controlled by three different major genes, which manifested as sporophore sterility.

What would I do if I became a millionaire Perhaps buy a cottage in the country, for us to share Where we would awaken to the song birds call Watch the leaves change colour in the fall Sit on the porch in the sun Seeing the world go by, and having fun Just think of all that country air, filled with the ozone of the sea Being woken in the dawn , by the waves crashing on the shore The crying of the gulls searching for food evermore Breakfast then out in the boat Cruising around islands ever so remote Playing a fresh fish on a rod, and line Going ashore and cooking it in a fire

如果我成为了一个百万富翁，我会做什么也许在国家中买一间小屋，让我们分享我们会对歌鸟呼叫唤醒的地方看树叶在秋天改变颜色在太阳下坐在门廊上见到世界过去，而且享受乐趣仅仅想到所有的国家空气，装满海洋的新鲜的空气了被在破晓方面唤醒，藉着在海岸上撞碎的波对食物的鸥搜寻的叫喊者永远早餐然后在船中的外曾经在岛的周围巡航这么遥远的玩在一支竿上的一条新鲜的鱼、和线向岸地去而且在火中煮它

Using Hwa-Lien and Wu-Feng-Shan radar data set respectively, the mean tangential wind component of Nock-Ten has been retrieved by original GBVTD method. It is found that the retrieved maximum mean tangential wind from HL is 14 m s-1 less than that solved by WFS data set. This large difference has been attributed to significant mean wind component perpendicular to the line connecting the radar and the typhoon center.

利用五分山和花莲雷达观测资料，分别透过GBVTD计算其轴对称切向风，结果显示，两座雷达计算之轴对称切向风最大值相差达14 m s-1，而这样的差异可归因於纳坦台风平均风垂直雷达观测分量较为显著所造成。

Holding the bow is like a teeterboard supported by thumb as the pivot and the cooperated forcing of forefinger and little finger produces a moment M. The "P-x-M Line Method" shows when playing a down bow, M increases with x and gradually changes its direction and this process is determined by P, the gravity and barycenter of bow. The "P-x-F Plane Method" shows that the most force-saving bowing path should locate in the lower part of this plane. The analyses of "Helmholtz Motion" and "Schelleng Diagram" indicate P and its range is in direct ratio with volume, velocity of bow, the approaching degree of the bow to the bridge and has some relationship with the quality of string and bow.

国内近期出现了用物理模型来研究小提琴运弓问题的尝试本文第一部分首先指出握弓类似于一个以***(F3)为支点的跷跷板，主要以食指(F1)和小指(F2)的施力配合，产生握弓力矩M；随后用"P-x-M直线法"证实：演奏下弓是M随的***而逐渐增大并转换方向的***，此***取决于P、弓的重力和重心；并首创"P-x-F平面法"，在x，F1，F2空间中证实：省力的运弓路径应在该平面中处于较低的位置第二部分通过分析"赫尔姆霍茨运动"和"Schelleng图表"指出：P及其变化范围和音量、弓速、弓与琴码的接近程度成正比，并与琴弦和弓自身的性质有关
