An intense femtosecond pulse tightly focused inside the transparent material will induce a multi-photon absorption process, leaves permanent structure changes with micrometer precision in the material. 飞秒激光脉冲紧聚焦到透明介质体内,将导致多光子吸收过程,促使材料体内形成一个微米尺度的结构改变。
A method to reform the mechanical in-side micrometer for bearings into the intelligent digit-al inside micrometer is put forward. 提出了一个将机械式轴承内径千分尺改造成智能型数字式内径千分尺的方法。
