The presence of BaO affected the TPR performance of Co/SiO2, and Ba loading of 2% increased the reduction degree of Co/SiO2 at the moderate temperature (450℃). The difference of the TPR performance between unpromoted and promoted catalyst samples could be ascribed to the induction of the reduction of BaO, and the interactions between barium oxide and silica, barium oxide and cobalt oxide.

研究结果表明，氧化钡明显地影响Co/SiO2的还原性能；添加2%氧化钡提高了Co/SiO2在中温(450℃)条件下的还原度；氧化钡的还原对Co/SiO2还原的诱导、氧化钡与氧化硅及与氧化钴之间的相互作用是导致Co/SiO2还原性能变化的原因。

Barium nitrate products are mainly used in the manufacture of barium oxide, barium peroxide and other barium salt, also used in the manufacture of optical glass and pottery glaze, etc..

硝酸钡产品主要用于制造氧化钡、过氧化钡及其他钡盐，也用于制造光学玻璃和陶器釉药等。

The scandium oxide doped in the barium-calcium-aluminate 5BaO·3CaO·2Al2O3·0.6Sc2O3 compound is supposed to be a carrier for aarium oxide or barium atom which is the electron source, and it plays the role in controlling and roplonishing the electron source.

在掺氧化钪的发射物质5BaO·3CaO·2Al2O3·0.6Sc2O3中，氧化钪的作用则在于它和铝酸盐中的可利用氧化钡结合为2BaO·Sc2O3，成为电子发射源氧化钡或钡原子的载体，它起控制和补充发射源的作用。

Solubility of barium chloride and barium oxide in hydrochloric acid, ethanol,acetone,ether and hydrochloric acid- ethanol,hydrochloric acid- acetone,hydrochlo- ric acid- ether has beeen studied and the separation of Ba O from Ba Cl\- 2 with hydrochloric acidethanol as the solvent has been proposed.

研究了氯化钡和氧化钡在盐酸、乙醇、丙酮、乙醚及盐酸-乙醇、盐酸-丙酮、盐酸-乙醚中的溶解性，提出以盐酸-乙醇为溶剂进行两者的分离。以 DBC- CPA为显色剂分光光度法测定氧化钡的含量，加料回收率为 98%～ 10 2 %，氧化钡含量为 0 。32 %时，平行测定 7次，相对标准偏差为 1。 58%。该法适于快速测定热处理盐浴中氧化钡的含量，对监控盐浴品质有指导意义

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
