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。

But, in the natural and artificial signal, a lot of signal phases don\'tvary linearly with time, for example, we usually use chirp signal in the radar technology,frequency step signal, linear modulation component of the ground echo in the SARtechnology, linear modulation component of the moving target echo, linear modulationcomponent while the airborn radar detecting the moving target, etc.

在自然界和人工信号中，许多信号的相位变化并不是随时间一次方变化，如雷达技术中常用的线性调频信号，频率步进信号，另外，SAR 技术中，地面回波所含有的线性调频分量，ISAR技术中，运动目标的回波所含有的线性调频分量，机载雷达探测运动目标时的线性调频分量，等等；傅里叶变换对此类信号分析所得的结果是信号在不同频率点上的能量分布，即信号在基函数上的投影。

The results showed that the difference of the style did not influence the occurrence of analogical reasoning.

实验结果表明目标信息与源信息二者文体的不同不会影响类比推理的发生，类比推理的结果能够整合进目标信息的表征。

The system gets two image of one object with two CCD, thus obtains depth from two CCD"s parallax. After investigating the operation spot and discussing with surgeons we use LED as markers, and get the marker"s 3-D position with a non-contact optics orientation method. After calibrating the CCD, processing the image, the system can figure out marker"s areal coordinates, get marker"s 3-D coordinate in dummy world coordinate system, thereby obtain instruments 3-D position and orientation. After the coordinate transformation and a series of orientation calculation, operation navigation comes true.

运用两个摄像机对同一目标从不同位置成像，进而从视差中恢复距离；通过对手术现场的仔细了解与手术医师的反复商榷，使用LED作为标志点，利用非接触式光学定位方法提取空间点位置信息：通过对摄像机的标定、图像处理及目标点重心的计算，求出空间点在虚拟世界坐标系下的三维坐标，从而确定了手术器械等的空间位姿，通过空间坐标转换及一系列定位计算，完成了手术导航实验系统。
