The shapes of the melting solid surface may be concave, convex or plane, while the perimeter of plane contact regions may be rectangular, circular, elliptical, parabolic and arc curve. The types of relative motion reviewed here are the movement of a solid PCM melting inside a heated capsule, the movement of a hot body through a melting solid medium, slide contact and rolling contact. The contact melting may be caused by temperature difference, pressure difference, friction and viscous heating. Finally, the research regions in the future are summarized.

内容包括各种形式的接触熔化，可归纳为：在接触形状上可以有凹、凸与平的面，而接触的周长可以是矩形、圆形、椭圆形、抛物线形与弧形曲线；相对运动的类型有固体相变材料在加热容器内熔化，加热体通过熔化固体介质的运动，滑动接触与滚、转动接触；引起接触熔化的原因有温差、压力差、摩擦与粘性热。

Methods:43 patients including 10 with mitral stenosis associated aortic regurgitation, 12 with mixed mitral valve lesions and 21 with mixed mitral valve lesions and combined with aortic regurgitation were studied.MVA determinded by (1) two -dimensional echocardiography with a cross-sectional area in the short-axis view (2DE),(2) pressure half-time using formula of 220/PHT,(3) color Doppler flow imaging with a jet cross-sectional area in the short-axis view with planimetry,(4) CDFI with a color jet width at the mitral valve orifice in the apical four-chamber view and long-axis view, assuming an elliptic mitral orifice, compared with the orifice area of excised mitral valve during mitral valve replacement.
