This optical switch has ultrasfast switching speed of several picoseconds, operating wavelength compatible of 1.55μm window, maximum rotation angle of 60°under 0.1nJ pump drive, low switching energy and large rotation angle.

该全光开关具有皮秒级超快开关速度，工作波长兼容于1.55μm窗口，在0.1nJ的泵浦驱动下最大旋转角可达60°，开关驱动要求低、旋转角大。

The transit time and gain characteristics of electrons which travel in the micro-channel plate gated by picoseconds high voltage pulse were simulated. The curves of the transit time versus the voltage pulse width and the voltage amplitude are obtained when the waveforms of the voltage pulse are Gauss, triangle and trapezoid.

For supracondylar fracture of humerus with obvious displacement,it is easy to make reduction,but the fixation and the maintenance of reduction is not easy; manual reduction with plaster or splint immobilization,though as the first-chosen method,has such shortcomings as infirm or loosening fixation of plaster or splint which may cause injury to blood vessels or nerves; open reduction may lead to further trauma to soft tissues and tissue adhesion,and to joint stiffness; the closed reduction with cross Kirschners wires under C-arm X-ray can avoid the above mentioned shortcomings and it is easy in operation.

移位明显的肱骨髁上骨折，复位容易，但固定及维持复位困难，手法复位石膏或夹板外固定虽是首选治疗方法，但石膏或夹板固定不牢固，易出现松动甚至可造成血管及神经损伤，而切开复位更易进一步造成软组织创伤，组织粘连，最终导致关节僵直功能障碍。本组C臂下闭合复位交叉克氏针治疗移位明显的肱骨髁上骨折避免了上述缺点，而且方法简单。肱骨髁上骨折；经皮克氏针固定；儿童；闭合复位
