查询词典 diamond boron

This paper researched the key part of framework aclinic slide structure on diamond frame sawing machine, which is the axially moving hydrostatic journal bearing. The major sawing motion form of diamond frame sawing was analysed. The structure designing model of the bearing according to the practice was established; and by the systemic analysis and research on the lubricating mechanism and performance, the designed scheme was proved out.

Heat flows derived from garnet, chromite/chromium-spinel and pyroxene of xenoliths, xenocrysts in Mengyin and Fuxian kimberlites are higher than 40mW/m〓 calculated from the pyroxene inclusions in diamonds, and the range of pressure is 20～40kb (equivalent to 65～130km). Metasomatism (as indicated by yimengite and lindsleyite in Mengyin) is very strong in this depth range. Lherzolite, wehrlite, and diamond-free high-Ca harzburigite around the world are derived from this depth also. The observation suggests that the low-Ca harzburigitic environment for diamond stability had been changed significantly when the kimberlitic magmas erupted. This resulted from fluid interaction with harzburigite. The geotherm of the Cenozoic lithospheric mantle beneath Eastern-North China platform is higher than oceanic one. The temperature from the interior of the Tan-Lu faults is higher than that from apart off the fault.

除金刚石中的辉石温压投点落于40m W/m〓占地温线上外，捕虏体及捕虏晶中石榴石，铬尖晶石及单斜辉石的投点均偏离该地温线，显示较高的地温特点，而且捕虏体及捕虏晶的压力范围多在20-40kb(相当于65-130km)间，该深度范围内地幔的交代作用特别发育，如蒙阴大量发育的沂蒙矿、钛钾铬石等就发育于该深度范围，世界范围内不含金刚石的高钙方辉橄榄岩、二辉橄榄岩、异剥橄榄岩也分布于该区中，一方面表明捕虏体的主要取样位置已不在金刚石稳定区中，另一方面也表明金刚石稳定的橄榄岩环境，在金伯利岩侵位并捕虏他们时已发现了明显的改造，这种改造作用主要是通过长期的熔流体与先存的橄榄岩相互作用的结果。

Since the type of eruptions that built Diamond Head tend to be monogenetic, geologists don't believe Diamond Head will erupt again.

由于类型的喷发，建造钻石头往往是monogenetic ，地质学家不相信钻石元首将再次爆发。

It is obvious that, in the interface between substrate and diamond film,there exists the lattice strain effect resulting from lattice misfit because ofthe difference between the lattice constants.The lattice strain effect willcause some nonnegligible influences on the processes of diamond films′growth.

在本论文中，我们首次提出了在异质衬底上研究金刚石薄膜生长机理时必须引入晶格应变效应微扰修正的物理思想，并借鉴固体能带应变微扰理论，首次在分子轨道理论框架下建立起计算晶格应变微扰效应的理论，其中包括提出了计算单个化学键应变张量的方法和由分子轨道波函数计算应变微扰Hamilton矩阵元的方法。

Methods The resinic artificial teeth were deposited with 50nm or 100nm nanometer amorphous diamond film after pretreated with ultraviolet radiation or polarization.The effect of different methods of pretreatment and thickness of nanometer amorphous diamond films on the wearing resistance of resinic artificial teeth was evaluated.

分别用极化和紫外光照射的方法对人工牙进行预处理后，在其表面分别镀制50nm和100nm的纳米非晶金刚石薄膜，通过对其耐磨性能的测试，评价不同预处理方法和不同厚度薄膜对提高人工牙表面耐磨性能的影响。
