The growth and nucleation rates of〓 cleavage face of YbYAB crystal are all very fast, because so many growth steps and growth centers were formed within only 2～3 second at the temperature near the saturate point. No spiral growth steps can be found, so growth mechanism is twodimensional nucleation. When the flux temperature increases for only 0.5℃ above the saturate point, the spiral melting holes are formed. The transformation from growth morphologies to melting morphologies is very sensitive to the temperature. When the temperature increases another 1℃, the spiral melting holes transform into two-dimensional nucleation melting holes.

YbYAB的〓解理面的生长及成核速度都非常快，在比饱和点低0.5～1℃的温度下，当生长2～3秒钟时，可以看到许多生长中心与生长台阶的形成，在较宽的台阶上还可以看到二维核的形成，没有看到螺旋中心，说明生长机理是二维成核生长；当温度比饱和点高0.5℃时，在〓解理面上形成螺旋状熔坑，这表明形貌由生长到熔化的转变与温度的关系是非常敏感的；当温度比饱和点高1.5℃时，螺旋状熔坑转变为二维成核状熔坑。
