底层金属

Methods Four groups of the nonprecious metalceramic crowns were fabricated according to the gradual reduction of the labial marginal types.

按照金属底层冠在唇侧边缘依次减少的冠边缘形式制作4组非贵金属金瓷冠。

Objective To improve metal-porcelain interfacial bond strength through treating the metal bottom with wiping crystal off and roughening it.

目的：通过用失晶粗化的方法对金属底层进行处理，以提高金属烤瓷的结合强度。

Anodising reaction proceeds in the sequence of growth of porous anodic alumina when the aluminum layer is consumed up to the underlying metal, and the growth of metal oxide under the bottoms of the alumina pores occurred simultaneously.

以电化学的方式在阳极产生氧化铝孔洞的同时，底层的金属同时被氧化而在孔洞底端成长出奈米点。以草酸、硫酸和磷酸不同的电解液和不同施加电压下观察奈米点的阵列。

The preparation of a wall, ceiling, or floor with strips of wood or metal to provide a level substratum for plaster, flooring, or another surface or to create an air space.

钉板条铺墙、天花板或地板前的准备工作，利用木条或金属条为室内地板材料立起水平底层或别的颊或者留出空气的空隙

Among those changes, CARAT＇s brightness showed a minimal change; a gradual stability of chromatics was presented and was limited within a certain range though the augment of opaques.

结论不透明层在达到一特定厚度时可完全遮盖底层金属色，其中CARAT组的这一厚度值最小，遮色能力相对较强。

A concentrated hue in the second thickness was found in CARAT ceramic which had high ability of opaque and had a stable hue of ceramic in comparison with other opaques.

结果试片明度随不透明层的增厚呈增亮趋势，并趋向稳定在某一厚度值而不再增加，该厚度值在不同品牌间有所不同，其中PCARAT系列明度变化最小；而样本色度也随不透明层的增厚逐渐稳定，到达一特定厚度时可完全遮盖底层金属色。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
