它是金属材料的重要性能指标之一。一般硬度越高，耐磨性越好。常用的硬度指标有布氏硬度、洛氏硬度和维氏硬度。布氏硬度（HB）以一定的载荷（一般3kg）把一定大小（直径一般为1mm）的淬硬钢球压入材料表面，保持一段时间，去载后，负荷与其压痕面积之比值，即为布氏硬度值（HB）。洛氏硬度（HR）当HB45或者试样过小时，不能采用布氏硬度试验而改用洛氏硬度计量。它是用一个顶角12°的金刚石圆锥体或直径为1.53.18mm的钢球，在一定载荷下压入被测材料表面，由压痕的深度求出材料的硬度。

SO2进入大气后，若大气干燥清洁，可停留～2星期。经高烟囱排放后，在.5km高空风的影响下，24h之后会有5%以上超越7km之外，6h后，能扩散到km之外。科学家曾估计过，我国大部分省份排放的SO2，有一半以干湿沉降方式沉降在本省范围，有2～3%沉降到周围省份，其它则沉降到较远的省份。大城市则更为突出，它们排放的SO2，仅2%左右沉降在本市内，8%则被传输到其它地方去了。高烟囱排放含硫烟气大大减轻了燃煤发电厂周边地区的大气SO2落地浓度，较为有效地改善了燃煤发电厂周边地区的大气环境质量。
