In this paper, based on the conjugate function and the dual programming of convex programming, with the dual cone, to conic programming, the dual programming is fully discussed, the expression of the dual programming is educed, the main dualities are proved, and the dualities of the familiar conic programming are studied.

以共轭函数和凸规划的对偶规划为基础，利用对偶锥的概念，全面讨论了一般锥规划的对偶问题，严格推导出锥规划对偶规划的表示形式，给出了锥规划的主要对偶性质，并用这些结果研究了常见锥规划的对偶性。

The growth dynamics of leaf length on stem and tiller could be described with a logistic model, leaf width with conic equation, and leaf shape with exponential function and quadratic equation. The effects of nitrogen and water conditions on leaf growth were quantified by the effective values of leaf nitrogen concentration and water content.

It shows that the exhaust resistance at the wind blast end reduces obviously, driven by the 800mA/12V small scale draught fan, average exhausting speed reaching above 4m/s, fairly enough to satisfy the air conditioner's demand for new wind volume. Meanwhile, the conic section of the horizontal profile and the linear design of the longitudinal profile of the exhaust end inner cavity and wind shroud for each outlet greatly reduce the flowed out exhaust, effectively lowering the wind blowing feel of the air conditioner user by playing the function of air diffusion.

经过计算和实际测试表明，该装置的送风末端风口阻力明显减小，在800mA/12V小型风机驱动下，出口平均风速可达4m/s以上，足以满足空调对象的新风量要求；同时，横截面采用2次曲线型设计、纵截面采用流线型的送风末端内腔和出口均风罩使气流流出后风速迅速衰减，起到散流器的作用，有效降低了空调对象的吹风感。
