As is the case with everyday objects such as wineglasses or guitar strings , objects made from lower - mass materials have higher characteristic frequencies than otherwise identical objects made from higher - mass materials 将原有的镁或硼以它们的同位素取代，我们可以制造出由不同质量的原子所构成的硼化镁。
Methods of analysis of wood preservatives and treated timber - quantitative analysis of wood preservative solutions and treated timber containing boron compounds - determination of total boron 木材防腐剂和经过防腐处理的木材的分析方法.含硼化物的木材防腐液和经过防腐处理过的木材的定量分析.硼总含量的测定
Research in this area is very active , and it appears that physicists will soon make further improvements and achieve a better understanding of what will provide a good pinning site in mgb2 目前这方面的研究非常活跃，而且看起来物理学家很快就会再做出进一步的改善，更加了解如何在硼化镁内提供好的固定位置。
Qinghai ridge boron & lithium co . , ltd , certificited in 2000 , is a aggregate resource corporation of mining boron mine , producing boracic acid , boride re - processing and selling industrial used salt 青海中天硼锂矿业有限公司成立于2000年，是集硼矿开采、硼酸生产、硼化物深加工、工业用盐生产销售的资源性企业。
Unlike high - temperature superconductors ( copper oxide materials that superconduct at temperatures as high as 130 k ) , mgb2 seems to be a traditional superconductor , albeit a novel variant 和高温超导体（主要成份为铜氧化合物，转变温度最高可达130k ）不同的是，硼化镁虽然是个新登场的超导材料，看起来却很像传统超导体。
Our team specializes in studying the physical properties of metallic compounds , so as soon as we heard about the report , we emptied all of our furnaces of existing experiments and started trying to produce mgb2 我们的团队原本就专攻金属化合物的物理性质，听到这个报告后，我们马上将所有正在进行实验的炉子空出来，开始尝试生产硼化镁。
According to experiments , lab6 , with high conductivity , good heat stability and chemical stability , low work function , and active cathode appearance , has become an ideal material for field emission array cathodes 经试验证明,六硼化镧( lab6 )具有高导电率和良好的热稳定性、化学稳定性、低功函数以及活性阴极表面,因此从理论上成为了场发射阴极的理想材料。
Using in situ formation of ternary boride base cermets hard phases through chemical reactions and sinterbonding onto steel substrates though liquid sintering we successfully prepared a kind of ternary boride base cermet 摘要通过化学反应将原料粉来生成三元硼化物硬质相并通过液相烧结烧与钢很好的结合，用这种工艺成功地在钢基体上涂覆了预压制的三元硼化物基金属陶瓷。
The fact that the shift in tc was a little larger than the simple prediction can be accommodated by bcs theory ? it indicates that the boron vibrations are more important to the superconductivity than the magnesium vibrations [ see box on page 87 ] 虽然这个温度偏移比理论值稍微大了一点，不过还是符合bcs理论的结果：在影响硼化镁超导性的因素中，硼的振动比镁的振动更重要（参见107页结构与键结） 。
Lab6 , as one kind of better material , is so perfect that it is important to research its chemical etching in the arts and crafts to be used in the preparation of emitting cathode , we simply state the chemical etching technical research in material of lab6 and have gainded graphics surface of lab6 而对六硼化镧的化学腐蚀在以其为阴极的阴极发射体制备工艺中起着至关重要的作用，本文简述了对材料的化学腐蚀工艺的初步研究，并得到了图形化的六硼化镧表面。
