People with dark skin may observe the onset of vitiligo at any time.

皮肤黝黑的人可能会发现在任何时候白癜风的发病。

The experimental results testify that the water-cooled silicon mirror with linear type microgroove runner can make the stability of laser output better and meet the need of stability in practical application although its absolute distortion is tinily larger compared with the water-cooled mirror with spiral type runner.

大量的台架实验结果和现场试验结果证明，虽然直线型微沟槽流道结构水冷硅镜镜面绝对热变形量与螺旋型流道相比略大，但动态热特性较好，激光器输出稳定性较高，能满足实际应用中对稳定性的要求。
