Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE. It is suggested that alkaline rocks in Hongyang area have the characteristics of subvocanics, and alkaline rocks in Hongyang and Miaoya areas all came from upper mantle and mixed with some substances of crust. Intrusion of alkaline rocks is related to the occurrence, development and evolvement of the deep rupture zone in the areas.

稀土、稀有元素主要富集于灰黑色粗面岩中，而在其他岩石类型中相对较少，同时岩石的片理化、黄铁矿化、硅化和碳酸盐化对稀土、稀有元素有进一步的富集作用；提出了本区的碱性岩组合具有次火山岩相的特征，讨论了本区碱性岩的成因，认为其与湖北庙垭地区的碱性岩可能均来自上地幔，并不同程度地混染了大陆壳的物质成分，其形成时代与断裂构造带的发生、发展和演化基本同步。

A special process named "silicification followed by carbonization" was adopted to solve the problems such as SiC grains forming on the SiO2 and poor cohesiveness between the SiC and substrate. Furthermore,this method is effective to prevent O atoms diffusing from SiO2 into SiC epilayer.

通过"先硅化再碳化"的工艺方法可以较好地解决SiO2/Si复合衬底上SiC成核困难以及粘附性差的问题，同时还可以有效抑制SiO2中的O原子向SiC生长膜扩散。

Studies on rock and ore micro fabric that control mineral preservation stratum of the deposit,and the siliconization and pyritization contacted with gold mine origin reflects the characteristic of syndepositiondiagenesis,which indicates the sediment-diagenesis and later stage mild reconstructive genetic mechanism of Shuiyindong gold deposit.

黔西南水银洞金矿是一特大型富金矿床，矿体成群多层、顺层产于龙潭组地层中，通过系统研究水银洞金矿赋矿地层岩石及矿石的显微组构特征，以及与金矿成因联系密切的硅化及黄铁矿化特征，均显示为同沉积—成岩特征，共同指示水银洞金矿沉积—成岩后期轻微改造的成因机制。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
