方向性

Then the new methods are applied to extract slub, which is the directional feature of fabric images. Instead of the past extracting method, in which the slub is regarded as fabric defects, slub is regarded as a texture feature. A more suitable Gabor filter is designed.

然后将新方法应用到织物图像的方向性特征—竹节纱的提取上，本文的方法不同于以往将竹节看作织物图像疵点的提取方法，而是将竹节看作一类纹理特征，设计更具有针对性的Gabor滤波器。

The sparsity of the field directionality was shown and an efficient way for sensing matrix construction was provided.

场方向性的稀疏度得到了证明，并提供了用于传感矩阵构成的高效方法。

To solve the directionality of spatial magnetic field measurement,two schemes including three-dimensional measurement and simultaneous measurement of transverse,longitudinal components are proposed.

为了解决空间电磁场测量中的方向性问题，提出了三维测量和同时测量横、纵向磁场的两种方案。

The results indicate that with increasing the strain at 280℃, the dendrite arms of AZ91D alloy get broken or stretched-out. With increasing the predeformation temperature under 20% strain, the deformation style of the dendritic structure of AZ91D alloy changes gradually from fragmentation to directional bending.

结果表明：形变温度为280℃时，随着形变率增加，部分枝晶臂逐渐伸长，枝晶破断现象加剧；形变率为20%时，随着形变温度的提高，组织的形变方式逐渐由以枝晶断裂为主转变为带有方向性的弯曲。

The forward directivity velocity pulse generated by strike slip fault in full space is studied.

本文在均匀弹性全空间中对走滑断层附近方向性速度脉冲作了定性研究。

Directional thermal radiation of canopy was studied and the related model was set up.

Triangular pyramid with the corners of the use of micro-structure of the pyramid as directional light, you need to be aware of rotation can not cause too much lower luminance.

利用三角金字塔与四角金字塔微结构来做光线的方向性，则需要注意到旋转角度不可过大容易造成辉度降低。

Compared to traditional method,this approach replaced tuning capac-itor with PIN diodes,made use of its characteristics of variable impedance to adjust the impedance through the bias voltage to achieve the autotuning of directivity.

与传统方法相比，该方法采用PIN型二极管代替调节电容，利用其阻抗可变特性，通过偏置电压来调节匹配阻抗，最终实现定向耦合器的自动方向性调节。

The algorithm handles the objective function and constraints separately, and adopts both directional and random search mechanism. It can avoid falling into local optimal point, which may appear in previous bionics random algorithms due to uncertainness of some parameters and/or without guiding search direction.

该算法将目标函数与约束条件分开处理，采用兼具方向性和随机性的搜索机制，避免了已有仿生类算法由于一些参数难以确定和无引导性的搜索方向而陷入局部最优的问题。

It is unsupervised, undirected evolution.

它是无人监督的、无方向性的进化过程。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
