Fifty-three primer combinations were found to amplify nuclear DNA of Chinese cabbage, properly. They amplified the fragments up to 4 381 with an average of the 83. Among them, 9 markers derived from 9 primer combinations were linked to the clubroot resistance gene.

筛选出的适宜53对引物组合共扩增出4381条带，占总扩增片断的33.50%，平均每对扩增出83条，其中9个组合扩增出与抗根肿病基因连锁标记。

Lastly,we present an algorithm to isolate real roots of a univariate spline, i.e., computing asequence of disjoint intervals such that each of them contains exactly one real root of agiven spline function, which is primarily based on the use of Descartes\' rule of signs withits B-spline coefficients and de Casteljau algorithm of B?

最后，基于B-样条系数的Descartes符号准则和Bézier曲线的de Casteljau算法，我们给出了一元样条实根分离算法，也就是计算出一列不相交区间，使得每个区间恰好只包含此样条函数的一个实根。

Firstly, according to electromagnetic field theory, the 2-dimensional (2-D) mathematical model of a three phase squirrel-cage Y802-2 induction motor is developed. Then general equations can be deduced from finite element discrete and functional analysis. The motor's 2D solving region of electromagnetic field is given based on the boundary conditions and assumption conditions of the squirrel-cage induction motor. Through finite element mothod and inner–outer convergence method, magnetic field distributions and magnetic forces of bars can be calculated in following rotor conditions: health rotor, one single broken bar, two adjacent broken bars, two broken bars with one good interval, two broken bars with two good interval and four adjacent broken bars.

本文首先根据电磁场理论建立Y802-2型三相笼型感应电动机二维电磁场的数学模型，并对其进行了有限元离散以及泛函分析，推导出总体方程；在基本假设和边界条件基础上，给出笼型感应电动机二维电磁场的求解区域，然后应用有限元并结合内外双收敛方法，对样机稳态运行进行数值计算，得出电机在转子完好、一根导条断裂、连续两根导条断裂、间隔一根两根导条断裂、间隔两根两根导条断裂及连续四根导条断裂六种情况下的磁场分布和导条所受电磁力的变化情况。

A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold;,through which a solitary log came floating ,black and conspicuous; in one place ,a long slanting mark lay sparkling upon the water; in another the surface was broken by boiling ,tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest ,was a smooth spot that was covered with graceful circles and radiating lines, ever so delicatedly traced; the shore on our left was densely wooded ,and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun. there were graceful curves ,reflected images ,woody heights ,soft distances ; and over the whole scene ,far and near ,the dissolving lights drifted steadily ,enriching it every passing moment with new marvels of coloring.

还记得自己刚开始船上生涯时所见过的那次辉煌的落日：宽阔的河面一片血红；不远处这红色明亮起来，变成金色，一根显眼的黑色圆森木从中漂过；这边，一根长长的浮标倾斜在水面上，熠熠闪光；那边，翻滚的波浪打破了宁静的水面，像猫眼石般色彩纷呈；微红的水流最缓和处，美丽的涟漪在平稳的水面上层层荡漾开去；左侧的河岸上丛林茂密；一条如银带般闪亮的小径从昏暗的树荫中蜿蜒而出，伸向远处；高高的密林之上有一根无枝无蔓的枯树，仅留有一根带叶的树枝在风中晃动，在太阳一泻千里的光辉里，它宛如燃烧的一团火；还有优美的波纹、水中的倒影、树木葱茏的高地、柔和的远景；放眼望去，由远及近，逐渐裉去的光线随波荡漾，每时每记得都以其新的奇妙着色为这条河添姿增彩。
