优质多抗甘蓝型油菜杂交种杂双4号的选育

A Redesign Method Based on Parameter-sensitivity Analysis for Plate Fin-and-tube Radiators

杂双4号是河南省农业科学院经济作物研究所选育的甘蓝型油菜细胞质雄性不育三系杂交种,其杂交组合是88A×P280。在2004年、2005年河南省油菜区域试验中,杂双4号平均产量3012.2 kg/hm^2,比对照杂98009增产8.81%。在河南省油菜生产试验中,杂双4号产量2392.5 kg/hm^2,比对照杂98009增产5.0%。杂双4号品质优良,经农业部油料及制品质量监督检验测试中心（武汉）检测,其芥酸含量1.60%,硫苷含量25.78μmol/g,含油量41.01%。该品种农艺性状优良、抗寒、抗倒伏,较耐菌核病、抗病毒病。

To set up a solid mapping relation between the internaJ structure of a radiator and its heat dissipation performance to enhance the system＇s performance in some bad working conditions, such as in an over-loaded or high- temperature environment, a redesign method based on parameter-sensitivity analysis is introduced here. According to the theoretical descriptions on the heat-transfer process given by forced-convection heat transfer theory, a mathematic model is built to weigh the significance of the radiator＇ s design parameters to the system＇ s heat dissipation performance. A sensitivity factor is derived by examining the effect of the variation in each parameter to the output of the system which quantitatively describing the range of the parameter＇ s influence to the system＇s performance. The new design method is expected to be a reference for radiator design under certain circumstance.
