surface graining meaning in Chinese

表面挛晶纹

The results indicate that the surface grain size of the steel sheets is smaller than that of the center by batch annealing , while it is on the contrary of the steel sheets by continuous annealing
结果表明，罩式退火后钢板表面晶粒比心部的细小，而连续退火后钢板表面晶粒比心部的粗。
( 2 ) with the condition of table 4 . 2 , the average reflectance decreases and the low reflectance vale moves towards shortwave , the influence on the extinction coefficient ( k ) of the films is very little , refractive index has trend of decrease and the thickness of the films decrease when increasing the total gas pressure , and the refractive index fix on a constant value when the total pressure exceeds a certain value . the phase of tio2 change from rutile to anatase and the size of surface grain change from big to small
( 2 )随着总气压的增加薄膜的反射低谷向短波方向移动;总气压对消光系数k影响不大;随着总气压的增加薄膜的折射率出现了下降的趋势,但当总气压达到一定的量值时折射率的变化趋于稳定;薄膜的厚度随总气压的增加而减少;随着总气压的增加tio2的晶体结构由金红石相向锐钛矿相转变,薄膜的表面的颗粒度大小由粗大变得微小细密。
