"Our material is hard enough to scratch diamond, and much harder than osmium diboride," he said.

而且其它超硬材料，包括金刚石和立方结构的氮化硼都是在昂贵的高压条件下制造出来的。

"We found that if we combine boron with osmium, we push the osmium atoms apart by only 10 percent from where they were in osmium metal, which is very good; you want to push them apart as little as possible," Kaner said.

我们发现，如果我们把硼和锇结合在一起，我们只能使锇金属中锇原子的分隔距离扩大10%，这已经非常不错了；如果你想尽可能地缩小原子之间的分隔距离，就需要寻找更好的过渡金属。

In the alkali-boron-silicon system basic fluxing agent,we use the combined effects of alkali metals,alkali earth metals and admixture s to replace lead,in order to produce environment-protecting unleaded fluxing agent for overglaze colors with low bismuth.

在碱-硼-硅系统基础熔剂中引入外加剂，通过多种碱金属、碱土金属及外加剂等复合效应来代替铅在熔剂中的作用进而研制低铋环保型无铅熔剂。

Complete borosilicate glassware system with support panel and base, heating mantle and clamps.

装有完整的硼硅酸盐玻璃系统和支撑面板与底座以及加热罩和钳子。

The paramagnetic resonance of the Fe3+ ions in sodium borate glasses has been studied.

It is worth noting that the pomegranate bonsai is strictly prohibited to use the East borer parathion (fenitrothion, speed eliminate loose), in order to avoid phytotoxicity.

的微量元素硼的缺乏，也可能造成不结实，这是必须的元素花粉管的发展，你可以买一些微量元素的肥料花店。

It was found by experiments thatboron increased the growth rate of pearlite, both in hypoeutectoid and eutectoidsteels.

硼有加速珠光体成长率的作用，无论在亚共析或共析钢中皆有同样的现象产生。

Research on the characteristics of RDX、 HNS、 PETN、 HMX and boron and carbon in them initiated by laser.

在RDX、HNS、PETN 和 HMX中搀杂硼和碳可以明显的提高药剂的激光吸收率，因而提高药剂的点火感度，缩短了点火延滞期。

Results showed that under the conditions of a reaction temperature of 60 ℃,a reaction time of 6 h and a catalyst consisted of 1.0% BF3-ether and 1.5% AlCl3,the yields of aromatic solvent naphtha and petroleum resin...

结果表明，采用两段聚合法，在催化剂三氟化硼乙醚络合物质量分数1.0%、三氯化铝质量分数1.5%、聚合温度60℃、聚合时间6h的条件下，芳烃溶剂油收率为71.1%，石油树脂收率最高可达20%；同时所得的芳烃溶剂油切割为120号和200号溶剂油，指标达到行业标准。
