查询词典 brookite

The results show that α-Al2O3 in the two kind s of coatings decreases while the γ-Al2O3 increases after spraying. Rutile-TiO2 transforms to brookite-TiO2 and the inners tress of coating was increased so as to aggravate the expansion of cracking. The pores are small but dense in the conventional coating while bigger but loose in the nano-structured coating. The pores in the nano-structured coating exist almost inside the partially melted region. The pores generated during spraying and the cracks generated during the course of thermal oxidization because of thermal stress are the direct reasons why coatings fail.

结果表明：2种粉末在喷涂之后，涂层中的α-A12O3均有所减少，生成了γ-Al2O3，金红石TiO2相转变成了板钛矿型TiO2相，增加了涂层的内应力，加剧了裂纹的扩展；常规微米涂层中的孔洞细小但密集，纳米涂层中的孔洞较大但不密集，且大部分的气孔都存在于部分熔化区的内部；涂层在喷涂过程中所生成的气孔以及热氧化过程中由于热应力而产生的裂纹是造成涂层失效的直接原因。

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。
