爱普生EPSON晶振Q22FA1280038800石英晶体压电效应
石英晶体的压电效应:石英晶体的外形,它具有规则的几何形状.这是由于晶体内部结构对称性的缘故.石英晶体有3个晶轴,其中Z轴是用光学方法确定的.Z方向上没有压电效应;爱普生石英晶振经过晶体的棱线,并垂直于光轴的X轴称电轴;沿X轴方向施加外力时,在垂直于此轴的棱面上压电效应最为明显;垂直于X-Z平面的Y轴为机械轴.沿Y与X方向施加机械应力(拉或压)时,在Y方向不产生压电效应,只产生形变.

压电效应简单来说是机械能与电能的互相转换.
顺压电效应:物质在沿一定方向上受到外力的作用变形时,内部会产生极化现象,同时在其表面上会产生电荷;当外力去掉后,爱普生晶振深圳代理商又重新回到不带电的状态.
逆压电效应:在电介质的极化方向上施加电场,它会产生机械变形,当去掉外加电场时,电介质的变形随之消失.爱普生EPSON晶振,Q22FA1280038800石英晶体
