The superficial grain noise of coating layer on battery electrodes is bad.

极片涂敷层表面颗粒噪声较强。

They are also quite useful in the analysis of noise problems, e. g. That of film grain noise.

它们对分析噪声问题(例如底片颗粒噪声)也是很有用的。

Ultrasonic flaw detection in large-grained materials is difficult because of multiple scattering from material microstructure (grain noise).

由于粗晶材料中材料微结构引起的散射(结构噪声)，使得超声探伤比较困难。

Just as grain size in silver halide film ultimately limits the amount of detail you can see in a photograph, the background noise produced by the sensor does much the same in digital imaging.
