chess board illusion

Moreover,the complex stages ventilation net was rationally set up by combining the chess-board type with the up-down alternate type.

同时,将上下行间隔式阶段通风网络和棋盘式阶段通风网络有机结合,建立起了二者混合式的阶段通风网络,较好地解决了用风段污风串联、漏风等问题。

A kind of high ordered checkerboard pattern suppressing algorithm of progressive optimization method;

渐进优化法的一种高阶棋盘格式抑制方法

A new method using nodal density as design variable of continuum topology optimization was proposed to resolve the checkerboard pattern.

针对连续体结构拓扑优化中出现的棋盘格式问题提出了一种新的以节点密度作为设计变量的优化方法,从而使设计区域内的密度场函数具有C0连续性。

A well-known error is the checkerboard pattern that occurs because of the artificial high stiffness and certain elements in the optimal process whose stability are not guarantee.

最后的优化结果表明:采用非协调元所得的优化解已经能够使用;如果再实施过滤技术,设计区域中的中间密度单元明显减少,优化结果会更加精致;使用两类单元的求解效率和优化迭代次数相近;非协调元比等参元具有更高精度的拓扑优化结果,能进一步克服棋盘格式。

Results: The effect of different antifungal drugs in combination can be determined using the checkerboard method, time-kill curve method, E-test and double disk diffusion method.

结果:多种方法可评价抗真菌药物联用的体外药效,如棋盘法、时间-杀菌曲线法、E-test法、双纸片扩散法等。

In order to remove the checkerboard patterns in an optimized topology solution,wavelet transform and cubic spline interpolation are combined to perform the topology extraction of a compliant mechanism.

针对拓扑优化结果中普遍存在的棋盘格现象,采用小波变换与三次样条插值相结合的方法,对柔顺机构的拓扑图提取进行了研究。
