The Frechet derivative of the cost function is determined via the solution of an adjoint partial differential equation, and the boundary shape is then modified in a direction of descent. This process is repeated until an optimum solution is approached. The advantage is that the cost function variation is independent of the flow field variation, with the result that the gradient of cost function with respect to arbitrary number of design variables can be determined without the need for additional flow-field evaluations. So each design cycle requires the numerical solution of both the flow and the adjoint equations leading to a computational cost roughly equal to the cost of two flow solutions.

虽然他们的研究成果大多数都可以在公开性文献上看到，但是其中一些具体的细节问题的处理方法却没有透露，比如：伴随方程如何离散求解才能减小最终梯度计算中的误差，使得设计过程有效地进行；伴随方程与流动方程的边界条件是不同的，如何合理地处理伴随方程的边界条件，才能推动设计过程朝着设计目标而发展；在减阻问题中目标函数如何定义，求解梯度的具体数学公式如何推导，如何通过数值方法来实现它们等。

Results The direct flow rate reached 0.549L/min when pressure difference was 4.90kPa(500mmH_2O), and the antidromic flow rate only reached 0.028L/min when pressure difference was 4.90kPa(500mmH_2O), the direct flow rate is much more than the antidromic flow rate.

结果：当瓣膜两端顺向的压强差为4.90kPa(500mmH_2O)时，流量可达0.549L/min；当瓣膜两端逆向的压强差为4.90kPa(500mmH_2O)时，流量为0.028L/min，顺向压差的流量大于逆向压差的流量。

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.

二项式产能方程只能描述高速非达西渗流，对于低渗压裂气井，地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样，二项式产能方程已无法描述气井的生产状况，必须建立新的方程。

The system characteristic, exists in any system, also exists in the enterprise flow, but because the system characteristic is hides to the system internality, just like the enterprise the constitution, but the traditional enterprise flow management and the management method, usually all by the outward appearance angle of view and backwardness indicators, to evaluate the condition that enterprise target reach, achieves the goal by the flow operation achievement the means, often neglects the constitution flow intrinsic physique the characteristic, even not mention to in order to conforms to the industry to need and the environmental variation, the development enterprise manages some kind of system characteristic which should have.

系统的特性，存在於任何系统中，亦存在於企业流程中，但是由於系统特性是隐於系统的内在，犹如企业的体质，而传统的企业流程管理与经营方法，通常皆以外观的视角与落后指标，以评估企业目标达成的状况，以流程运作作为达成目标的手段，往往忽略构成流程内在体质的特性，更遑论为符合产业需要与环境变化，发展企业经营应该具备的某种系统特性。

The study also summarizes the theories of rural population flow both home and abroad from the economic perspective, and makes the model of the rural population flow in the background of politics, Economy, society and culture in the transition period of China upon the binary economic structure theory, by-business theory,"push-draw"theory, anticipated revenue hypothesis, new labor force move and other population flow theories. Through the empirical analysis the study has demonstrated the economic motivations of population flow in the rural areas of Henan Province.
