高速度

Through quantitative calculation, the conclusions are drawn: 1it was obvious that the south was faster than the north; contrast of economic level has reversed since reform and opening.2The reasons accountable for these changes consist of politics, export strength,economic system,input intensity (special foreign direct investment), industrial structure and so on.3Social-cultural elements have certain influence by all means.4To turn the north tardy, we should quicken the pace of reform and opening in the north, make efforts in restructuring big and middle state-owned enterprises, vigorously carry out the strategy of making the country strong through science and education.5The north must grasp opportunity, build new economic growth pole, retransfer and upgrade industrial structure as soon as possible.

通过定量计算得出结论：经济发展速度南快北慢现象是明显的，经济发展水平改革开放前北高南低，目前则是南高北低，致使中国经济发展出现了新的不平衡。南快北慢的原因是：地缘优势和超前观念所获得的政策倾斜，导致了出口能力和投资强度的差别；工业结构(特别是所有制结构和轻重工业结构)的作用也很明显，而国家投资的作用很小，且越来越不重要。扭转北慢的对策是加大北方改革开放力度，切实搞好国有大中型企业改造，大力实施科教兴国战略；北方要注意把握机遇，构筑新一轮经济增长点，尽快实现产业结构的升级和转型。

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。
