In general,the convergent sequence and bounded set are concepts only in topological spaces.

收敛序列和有界集一般是拓扑空间中的概念，文章首先引入序列收敛C和L-空间(给出某种序列收敛关系的向量空间)，然后在其中定义有界集。

It is proved that when all the ratios of the generic term of a subaddtive sequence to its ordinal number form a lower bounded sequence,the ratio sequence must have limitation .

从这一结果出发证明了，当定义在(0，+∞)上的次可加函数与其自变量之比为有界函数时，次可加函数必存在上下确界函数，并证明了其上下确界函数均为齐次线性函数。

127 Ma. These ages suggest problems in stratigraphic correlation, indicate that there is considerable diachroneity in the timing of volcanism and sedimentation in the Middle and Late Jurassic Yanshan orogen, and cast doubt on the traditional interpretation that the Tiaojishan-Tuchengzi sequence is bounded by regional unconformities dated at ca.

这些测年数据说明以往的地层对比是有问题的，燕山造山带在中、晚侏罗世所发育的火山岩和沉积岩地层是穿时的。

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。

In this dissertation, the best simultaneous approximation with weight to infinite sequence from simultaneous-suns in complex normed linear space is considered, and in the case when the weight satisfies a certain condition, the characterizations of approximation from a simultaneous-sun and uniqueness of approximation from a RS-set are obtained; moreover, in the case when the weight is free, the characterizations of approximation to a totally bounded sequence from a convex set are established.

本文在复赋范空间中研究了同时太阳集对无限序列的加权同时逼近问题，在权满足一定条件时，通过把所研究问题转化为连续向量值函数空间中相应集对一个上半连续函数的最佳逼近问题，得到了逼近的特征和RS集逼近的唯一性定理，有例表明它们是已有结果的本质推广；在权不受限制时，得到了凸集对全有界序列逼近的特征。
