The improved e-N method can also yield results well agree with those obtained by DNS.4 The transition prediction for boundary layers on cones with different key parameters such as angle of attack, cone half angle and the Mach number of the coming flow, have been made, to show the reliability of the modified e-N method.5 For the calculation of base flow, boundary layer equations can be used in the case of small angle of attack.

但是它要依赖于对初始扰动的正确预估，这显然又取决于更多飞行数据的积累和分析。e-N方法的转捩预测结果与直接数值模拟得到的结果也吻合较好。4通过对不同来流攻角、不同半锥角和不同马赫数的三维圆锥边界层的转捩位置进行预测，证实了改进的e-N方法对于三维边界层转捩预测是可靠的。5对于基本流的计算，边界层方程可以用于小攻角的情况，其计算量远远小于直接数值模拟，但背风面的剖面不可靠。

The concepts of Hausdorff dimension and measure have been introduced for near one hundred years. There are lots of works have been done on the calculation and estimation of Hausdorff dimension, such as the result of self-similar set which satisfies open set condition.

Hausdorff维数与测度的概念被引入至今己近百年，Hausdorff维数计算与估计的研究己取得相当进展，如关于满足开集条件的自相似集的结果，但对Hausdorff测度的计算而言所得的结果却不多。

An estimate of the Hessian of the Lagrangian is updated at each iteration using the BFGS formula.

由于自变量的维数很高，这样的问题是被分解成多个低维子问题来求解的。

Secondly, the paper is expanded from follow three aspects: the virtual design, the virtual process and the product data managementduring the developing the torque converter. Applying the key technique of concurrent engineering---design for function, design for assemblyand design for manufactureof the method of design for "X", the virtual design of the torque converter is accomplished in CATIA V5. Then the model constitution and the simulation of virtual process of the torque converter is done in CATIA V5, including the model constitution and the simulation of 5-aixe NC virtual process of the vane, the model constitution（material:PVC） of the idler pulley rapid prototypingand the virtual assembly and the motion simulation of the torque converter, etc. 3-D data exchange between various CAD systems is realized by using STEP standard. The lever of classing the character model of the torque converter is given. And the access authorization is set up and given to manage the partners' reading/writing the product data.
