The contents of N, P, K in leaves were examined by regular leaf analysis. The results showed that the N content was higher in leaf blade than in leafstalk. N content in leaf was gradually reduced along with the vine growth. N, F, K fertilized at 20 to 40 cm soil layers significantly increased N content in leaf. But N content in leafstalk was less affected by N fertilization depth and growing season. P content was higher in leafstalk than in leaf blade. Less change of P content was noticed in leaf along with vine growth. However, N, P, K fertilized at 40 to 60 cm soil layers significantly promoted P in both leaf blade and leafstalk. K content in leafstalk was much higher than in leaf Wade. No obvious influence was noticed by fertilizing depth. But K content in leafstalk was significantly increased due to applied K fertilizer in late growing season.

结果表明，酿酒葡萄叶片中氮含量远高于叶柄，叶片中氮素含量随着生育期的延长逐渐降低，而叶柄中氮含量随施肥深度增加和生育期延长而产生的变化很小，40cm的施肥深度能显著增加叶片中氮素含量；叶柄磷素平均含量高于叶片，全生育期叶片磷含量变化很小，而施肥60cm深度显著促进了叶片和叶柄中磷含量的提高；叶柄中钾含量远高于叶片，施肥深度对叶柄和叶片中钾含量未产生明显影响，但生育后期追施钾肥显著提高叶片钾含量；施肥深度达到40cm时酿酒葡萄的产量最高，而60cm的施肥深度产量显著下降。

Through the analysis of the experimental and numerical calculation values, hereinafter gives the description of the characteristics of the flow and heat transfer within the rotating blade cavity. Influenced by the inflow structure and the centrifugal force, the air flow rate on the top of the blade is bigger than that at the bottom, therefore, there exists radial component velocity which may make the buoyancy force weaken the heat transfer behavior of the blade.

通过实验和数值计算的结果的分析，发现气流在旋转叶片腔内的一些流动和换热特征：在进口流动结构影响和离心力的作用下，使得叶片顶部的气流流量大于底部的流量，因此流体存在径向分速度，可能是这种径向分速度造成浮升力对叶片的换热起降低的作用。

This text proceed with the theory of the vibration, utilize typical elastic hinge law analyze structure dynamics characteristic when the blade is quivered to instability, and then use relevant knowledge of blade vibration to simplify the model and the aerodynamic force of the vibration. Through the simplification, we can get the equation of the blade, which is dispersed to its instability. Then VISUAL BASIC procedure is utilized to work out thecharacteristic value of vibration and the vibration frequency.
