In the self-bred progenies of autopolyploid,we found that a very few chimaeraexist in the cells of root tips,but most of them had no change in ploidy. We also found13 diploid plants in the experimental plot (ratio is 0.46%) and can be divided into 4categories.
在部分同源多倍体株系的自交结实后代中,随机取样进行根尖染色体检查,结果表明多倍株系体的自交结实后代倍性没有变化,但发现有个别细胞为不同倍性的嵌合体;田间观察到分离出来的极少数正常二倍体,占0.46%,按照形态特征可以分成四个不同的类型。

And then some ellipses that AUGR estimator is better than the OLS estimator and AUGL estimator is better than the OLS estimator are given, respectively.Second, the definition of the almost unbiased unified biased estimator is proposed. This definition includes the familiar almost unbiased estimators in literatures, and it is the unified expression of the familiar almost unbiased estimators. Followed the biased and variance are compared of AUUB estimator and the unified biased estimator, respectively. AUUB estimator has smaller bias than UB estimator and the variance of AUUB estimator is between the variance of UB estimator and 4 times of the variance of UB estimator. Finally the properties of AUUB estimator are discussed. The conclusion is gained that there are parameters made AUUB estimator is better than OLS estimator in terms of their mean square error. The sufficient and necessary condition that AUUB estimator is admissible is given. The ellipse is given that AUUB estimator is
然后给出了几乎无偏统一有偏估计的定义,该定义包括了文献中常见的几乎无偏估计,实现了常见几乎无偏估计的统一表达式;接下来我们比较了几乎无偏统一有偏估计与统一有偏估计的偏度与方差,得出了几乎无偏统一有偏估计比统一有偏估计有较小的偏度,几乎无偏统一有偏估计的方差介于统一有偏估计的方差与统一有偏估计的方差的四倍之间的结论;最后我们对统一有偏估计的主要性质作了讨论,证明了存在参数K,S使得几乎无偏统一有偏估计在均方误差意义下优于最小二乘估计的结论,给出了几乎无偏统一有偏估计为可容许估计的充要条件,还给出了在均方误差阵意义下几乎无偏统一有偏估计优于最小二乘估计的椭球。

Fruit trees and flowers, birds and animals, shimmering tiles, and the gleam and murmur of running water—these are the vibrant and delicate substances from which, like a beautiful carpet, the Islamic garden is woven.Indeed, Islamic carpet design and garden layout go hand in hand.Garden carpets depict in a stylized manner the chahar bagh, or fourfold garden with its intersecting axial watercourses surmounted by a central fountain.In addition, they depict symbolically the vegetation planted in actual gardens:the shade-giving plane tree, identified with the Tuba tree in the Quran; the cypress representing death and eternity; and fruit trees standing for life and fertility.The central cartouche can interpreted as a platform, which in real gardens was often surmounted by a pavilion.These form the basic and timeless design formula of the Islamic garden—one or more quadripartite sections defined by narrow water courses—which has its roots in ancient Persia where the archaeological remains of Achaemenid palaces trace the outlines of pavilions overlooking carved stone channels.

Gradually, the separate sine waves have become visible. The dominant signal, corresponding to a planet with about the same mass as Jupiter but which orbits 55 Cancri A more closely than Mercury orbits the sun, was detected in 1996. Two further sine waves emerged in 2002, corresponding to one planet that has the mass of Saturn and is also orbiting more closely than Mercury, and another with four times the mass of Jupiter that is located in what would be Jupiter's orbit.
逐渐地,&正弦波&曲线出现明显的分离。1996年,科学家探测到了起支配作用的讯号,这种讯号表明发出讯号的行星与木星有着相同的质量,但它围绕恒星&55 Cancri A&运行的距离比水星围绕太阳运行的距离还要小。2002年,另外两个&正弦波&曲线被发现,它们也分别代表两颗行星:一个行星有着土星的质量,围绕恒星的距离也比水星围绕太阳的距离要小;另一个行星有着木星质量的四倍,其位置将会预计在木星的运行轨迹上。
