This clearly indicates that the negative value of dρ/dT in CdYb QCs is mainly due to the quasiperiodicity because these QCs are stoichiomeric compounds with a very narrow single phase range. Positive dρ/dT and anomalously large MR reported previously are found to be due to the existence of free Cd in the samples.

这清楚地显示CdYb准晶的负电阻温度系数是由於准周期导致，因为CdYb准晶是一种单一相范围极窄的当量化合物，以前的研究说其具有正的dρ/dT和异常巨大的磁阻是由於样品中含有金属Cd。

Under suitable conditions, an almost sure central limit theorem is obtained for the product of the partial sums of stongly mixing positive random variables.

Competition comes to Mexican telecoms 竞争降临墨西哥电信 Talking and saving 边通话,边省钱 Aug 20th 2009 | MEXICO CITY From The Economist print edition Mexico's dominant telephone firms are under attack 墨西哥占垄断地位的电话公司正遭受冲击 AFTER years of exorbitant telephone prices, Mexico's beleaguered consumers are finally getting a reprieve.

在经历长期过高的电话资费标准之后，久遭盘剥的墨西哥消费者终于迎来些许喘息。现在，墨西哥本地固定电话收费采用类似拉美其它地区的政策－不管通话时间多长，都以 1.5 比索(0.12美元)封顶。

Hence, a necessary and sufficient condition for the positivity of polynomials of arbitrary degree is presented in this paper. A practical algorithm to express this condition in terms of the coefficients of the polynomials is also given.

由此提出了任意阶多项式为正的一个充要条件，也提出了一个实用的算法，从而可以只用此多项式的系数来表示得到的充要条件。

But, atmosphere of a school falsely of problem still existence:on the teaching, excessively Be fixed attention on to employment, make university student unilateral to pursue "certificate" and rush through a field of the phenomenon of "the set reads" pretty much universal, lost humanities character;On the study, minority of classmates study desultoriness at ordinary times, the cheat in an examination is nothing new;Parts of classmates thought last value the study of professional knowledge, the collective idea is weak thin;The classmate that still has craves for to play joy and pursues to enjoy.

但是，学风不正的问题仍然存在：在教学上，过分着眼于就业，使得大学生片面追求"证书"、赶场"套读"的现象十分普遍，丧失了人文素质；在学习上，少数同学平时学习散漫，考试作弊屡见不鲜；部分同学思想上只重视专业知识的学习，集体观念淡薄；还有的同学贪图玩乐，追求享受。

Using the method of blow up lower and upper solutions, the existence and boundary behavior of positive boundary blow up solutions for some elliptic systems of competitive type with singular weight functions are obtained, here the singular weight functions are permitted to be bounded in some parts of the boundary, and to go to infinity or even oscillate in other parts.

利用爆破上、下解方法，本文建立了带奇异权函数的竞争型椭圆方程组正的边界爆破解的存在性和边界行为，这里奇异权函数可以在边界的某一部分有界，而在其他的部分趋于无穷或者震荡。

The effect of tilting in oxygen octahedra on the dielectric properties is due to the interoctahedral angle increasing to 180℃ consuming the thermal energy, which results in the less effect on polarizability with increasing temperature.

氧八面体扭转能使介电常数温度系数朝正的方向变化的本质是，氧八面体间角吸收热能朝180℃变化，导致纯温度变化对极化率的影响变小。
