查询词典 Xn.

A Banach space X with a unconditional basis {xn} is said to have the property P if, every bounded block basis sequence of {xn} spans a complemented subspace of X.

称一个带无条件基｛xn｝的Banach空间有性质P，如果｛xn｝的每一有界块基序列都张成X的可补子空间。

Paul Erds once posed the following problem about real line R: is it true that, for every infinite set X, there is a closed set E with positive lebesgue measure such that E doesn't contain any subset similar to X (I.e., there is no subset of E, which is a linear homeomorphic image of X). In 1984, K. J. Falconer proved the following: for a decreasing sequence of positive numbers {xn} such that \%lim\%xn=0 and \%lim\%(xn+1)/=1, Erds problem has a partial positive answer.

叶盛 Paul Erds曾提出如下关于实直线R的问题：是否对R的每一个无限子集X，都存在一个具有正测度的闭子集E，使得E的任何子集都不相似于X(E的任何子集都不与X线性同胚)。1984年，Falconer证明了如下结论：对于一个满足limxn=0和lim(xn+1)/=1的单调递减的正实数列{x n}，Erds问题有一个部分肯定的解答。

Elements from this sequence are treated as if they were additional positional arguments; if there are postional arguments x1,...,xN , and "expression" evaluates to a sequence y1,...,yM, this is equivalent to a call with M+N positional arguments x1,...,xN,y1,...,yM.

这个有序类型对象的元素被当作附加的位置参数处理；如果存在有位置参数x1，。。。，xN ，并且&*exprsiones&的计算结果为y1，。。。，yM，那么它与具有M+N个参数 x1，。。。，xN，y1，。。。，yM 的调用等效。

In general, when a given predicate P, x1, x2,..., xn is the object variables, P (x1, x2,..., xn) is not a proposition, because he can not determine the true value, in order to make it a proposition , use the constant instead of nn-object object variables ...

一般来说，当谓词 P给定， x1，x2，…，xn是客体变元，P(x1，x2，…，xn)不是一个命题，因为他的真值无法确定，要想使它成为命题，要用n个客体常项代替n个客体变元。。。。

The experimental results show that when TCAR is about 700 ℃ XN for limestone is maximum, and the optimum TCAR for dolomite is about 650℃. Although XN for limestone is much higher than dolomite, the difference of their YN is little when TCAR is in 650~700 ℃. And if TCAL is beyond 1050 ℃ XN for limestone decays sharply, but it is negligible to dolomite. XN for dolomite is far higher than limestone in the high TCAL. XN for limestone decreases with the particle size increasing, and there is an optimum particle size range with particle size increasing which XN for dolomite reaches maximum in. The particle size plays a more important role in limestone carbonation process than dolomite.

结果表明：TCAR为700℃时石灰石的XN最高，白云石则在650℃时XN最高，在650～700℃时白云石的XN远高于石灰石，但它们的YN相差不大；当TCAL超过1050℃时石灰石的XN急剧衰减，而白云石的XN则衰减程度不大，在高温煅烧时白云石的YN比石灰石更高；随粒径的增大，石灰石的XN逐渐减小，而白云石则存在最佳的粒径分布使XN最大，粒径的变化对石灰石的XN影响更大。

The basic idea of DR is to apply the extended Dixon resultants method to the system of multivariate polynomial equations, by taking x1,x2,…,xn-1 as variables and xn as parameter.

基本思想为对于MQ问题，把x1，x2，…，xn-1当作变元，而把xn当作参数，然后利用和改进扩展Dixon结式方法求解该类系统。

Elements from this sequence are treated as if they were additional positional arguments; if there are positional arguments x1,..., xN , and expression evaluates to a sequence y1,..., yM , this is equivalent to a call with M+N positional arguments x1,..., xN , y1,..., yM .

如果存在有位置参数 x1 ，。。。， xN ，并且*exprsseion 的计算结果为 y1 ，。。。， yM ，那么函数就是有M+N个参数了， x1 ，。。。， xN ， y1 ，。。。

XN, and expression evaluates to a sequence y1,..., yM, this isequivalent to a call with M+N positional arguments x1,..., xN, y1,...

如果存在有位置参数 x1 ，。。。， xN ，并且*exprsseion 的计算结果为 y1 ，。。。， yM ，那么函数就是有M+N个参数了， x1 ，。。。， xN ， y1 ，。。。，yM 。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
