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.

文章总结了国内外从经济方面研究农村人口流动的基本理论，特别是在二元经济结构理论、兼业理论、"推——拉"理论、预期收入假说、新劳动力转移理论等人口转移理论的基础上，结合中国转型期的政治、经济、社会、文化背景，构建了转型期中国农村人口流动的理论模型；经过实证分析，对河南省农村人口流动的历史过程和现状有了较为全面的认识，这对河南省农村人口流动的经济动因有了明确的认识。

Cash flow plan is another important activity in cash flow management. It expresses the cash flow forecast and decision in value way so that they could be understood by the persons who will carry it out. It plays a carrying-on role in cash flow management.

现金流量计划是企业现金流量管理的又一重要内容，它要将现金流量预测和决策结果以价值方式，用具体的和现金流量管理人员可以理解的方式详细地表现出来，作为后续管理活动的重要依据，因而它在现金流量管理活动中处于承上启下的地位。

I flow by valleys seeing birds sing and flowers radiate their fragrance; I walk by grassplot hearing insects and frogs sing.I walk by fencing seeing the first verdure on top of twigs.I flow into wellspring and become cliffside waterfalls to wash and dress up ridges and peaks;I flow into rivers and become sprays to sing fair-sounding love songs for the rocks on the shores.I flow into lakes and become blue soft waves to be stay together with green hills to receive sunrising and moondown. Finally, I come to you to wait for your acceptance.

我流经山谷，看过鸟语花香；我走过草地，听过虫鸣蛙鼓；我走过篱落，看过枝头的第一抹新绿；我汇入泉源，化作飞泉瀑布，给峰峦梳洗打扮；我汇入江河，化作浪花朵朵，给岸边的岩石唱起动听的情歌；我汇入湖泊，化作温柔的碧波，和青山一起，共同迎接日出月落；最后，我来到你面前，等待你的接纳，我想你是海，你一定不会因我的渺小而拒绝我的到来。

Secondly, by using the connection, we prove that the minimal continuous semi-flow is the minimal continuous flow if its time-one map is open, and for any minimal continuous semi-flow, there is an invariant residual set such that the restriction to the set is a minimal continuous flow.

为此，我们首先建立了它与其时间1映射极小集的联系；然后，利用这种联系证明了：若时间1映射为开映射，则它是极小的连续流，并且一般地说来，对任意极小连续半流，存在不变的剩余集，使得它在这不变集上的限制是极小的连续流。

The present study initially put forward that the overestimation to underestimation of actual flow rates by the flow rates calculated using the hemispheric flow convergence method is due to the gradual change of isovelocity surface area in different zones of the flow convergence region, which was proven in our in vitro, animal and human studies.

7血流会聚法对二尖瓣狭窄瓣口面积、室间隔缺损分流量的确定也是一种较为准确、可靠及影响因素较少的方法。(8)本研究首次提出由于不同血流会聚区等速表面形态变化导致半球血流会聚方法计算流量从高估到低估实际流量的论点，并在离体、动物及人体研究证实。
