It is proved that the least squareestimators of linear estimable functions of regression coefficients areadmissible under matrix loss and minimax. The necessary and sufficientexistence conditions are derived for the uniformly minimum riskequivariant estimators of linear estimable functions ofregression coefficients under an affine group and a transitive group oftransformations respectively. It is also proved that there are no UMREestimators ofthe covariance matrix and variance under an affine groupof transformations and quadratic loss functions.

本文证明了回归系数的线性可估函数的最小二乘估计是极小极大的且在矩阵损失函数下是可容许的；还分别在仿射变换群和平移群下导出了存在回归系数的线性可估函数的一致最小风险同变估计的充要条件，并证明了在仿射变换和二次损失下不存在协方差阵和方差的 UMRE 估计。

So before applying Mather's theorem of connecting orbits to concrete Hamiltonian system, we have to check whether the set W〓 is empty or not, and which cohomology classes are C-equivalent. In present paper, by investigating the topological structure of action minimizing sets near a co-dimensional one torus which is preserved under generic perturbations and becomes hyperbolic in nearly integrable Hamiltonian system.

与传统的Poincaré-Melnikov方法相比，我们方法明显优越之处在于，一方面我们的方法不仅可以得到双曲环面之间的异宿轨道，而且当该环面附近的其它环面破裂时，可以得到不同Mather集之间的连接轨道，另一方面，我们把异宿轨的存在性的证明转化为双曲环面极小同宿轨的某种弱孤立性的证明，所需条件比Poincaré-Melnikov方法弱得多。

Finally,as to an equicontinuous homeomorphism on a compact metric space,...

最后，针对紧致度量空间上的等度连续同胚，利用空间的极小性和紧致性，得到以空间中某有限个点的有限长轨道为中心，以ε2为半径的开邻域构成的有限子覆盖，并利用f的等度连续性，由该子覆盖构造出以空间任一点的有限长轨道为中心的开邻域所作成的有限子覆盖，进而得到所要结论。

Let be a homeomorphism, the following statements were obtained: if is distal and has POTP ,then does not have the average shadowing property; if is equicontinuous and has the average shadowing property, then f is minimal; let :X→X be distal and chaintransitive, then does not have POTP; is distal if and only if is distal.

设是个同胚映射，得到了如下结果：若有POTP且是distal的，则不具有平均跟踪性；若有平均跟踪性且是等度连续的，则是极小的；若是distal的且是链可迁的，则不具有POTP；是distal的当且仅当是distal的。

The motor molecule forms bipolar thick filaments that interdigitate with thinner actin filaments in the saromere, forming the basic contractile unit of muscle.

在所有的分子马达中，关于肌球蛋白的研究最多。肌球蛋白是肌肉收缩的关键成份，由它们形成的双极粗丝在肌节内同肌动蛋白细丝交叉对插，构成一个收缩单元。

It had a modern look, sloped armor and an octagonal shaped FCM turret but a poor armament with its 37mm SA18 L/21 gun and a coaxial MG (very few could be rearmed with the 37mm SA38 L/33 gun).

它拥有一副现代化的外观造型，装备了倾斜装甲和八角形的FCM炮塔，可是武器装备却很孱弱——只有1门37mmL/21的SA18主炮和1挺同轴机枪（只有极少数改装了37mmL/33的SA38主炮）。

Another property that has 500 times of antioxidation effect of that of Vitamin E, belonged to flavonoids family in Young Barley Grass Powder is 2-O-GIV.

大麦苗中的另一个抗氧化成分「2-O-GIV」，是属於黄酮类家族的一份子，「2-O-GIV」对紫外线的抗氧化效果极佳，甚至是同剂量维他命E的500倍之多。

为使产品继续保持国内先进、国际一流的水平，公司拟定2005年同国外电子投资商合资，合资后以较大的投入，实现较大规模的技术改造，达到年产驻极体6亿只的能力。

Among Chen Qiang's works of every period, there have always been some paintings that employ an empty space in the center. The empty areas maintain the eye shape and its distortion, or similar empty areas. If we regard the calm, one-colored strokes which join the background within the eye shapes as a visual absence, then we could very easily respond with the same shapes.

陈墙每一个阶段的作品中总有部分作品在幅面居中部分留空，这个留空部分大致保持眼睛的形状及其变形或者类似空白，如果把眼睛形状内与整幅背景连成一片的单色平涂看作切断联想的茫然无视，它造成的观看极能与其构成同状对应。

CPU cache size is also one of the important indicators, but also the structure of the cache on the CPU speed and size of the impact of very large, CPU cache in the operating frequency is extremely high and the processor is generally the same frequency of operation, efficiency is much larger than system memory and hard disk.

缓存大小也是CPU的重要指标之一，而且缓存的结构和大小对CPU速度的影响非常大，CPU内缓存的运行频率极高，一般是和处理器同频运作，工作效率远远大于系统内存和硬盘。
