The research about segment of labor market are plentiful, however as a limit of data, they have not gave a index of measure the degree of segment in labor market. 由于缺乏城乡劳动力市场分割程度的测度指标,所以不能在横向及纵向上比较中国城乡劳动力市场分割程度的差异及演变。
With this algorithm we can segment out several dark areas from a night image by setting an upper limit of the dark area ′ s gray-level. 这种分割算法的重点在于对黑暗区域搜索、分割策略的制定和有效黑暗连通区域的判别。
For the huge segment data case, however, the traditional operations have very low efficiency or even can not proceed because of the limit of memory space. 但是,如果数据量特别巨大,由于受到存储空间的限制,传统方法的执行效率会特别低下甚至无法进行。
Utilizing functions of self-adaptive, antigen recognition and memory of immune system, this method has combined with genetic algorithm to segment image. The experimental results indicate that this new approach is effective for image segmentation, which overcomes the limit of object comparing with other traditional ways. 利用生物免疫系统自调节、抗原识别和记忆功能,结合遗传算法对图像进行自适应区域阈值分割,试验结果表明该方法能够克服传统阈值方法对目标大小的限制,是一种有效的图像分割新方法。
This paper has discussed the two problem, especially discuss the length of the anchoring segment in the case of the anchoring segment drill through the different rock which has different t& limit shear stress between the borehole wall and the cement mortar. 本文就这两个问题做了初步的探讨,重点讨论了锚固段穿越不同岩性的岩体情况下,锚孔壁对砂浆的极限剪应力t与总锚固段长度之间的关系。
The Otsu method was employed to segment the image. For the limit of steel bar shearing, there may be black holes and cracks appear on binary image after image segmentation, which would lead counting error. 使用最大类间方差法对图像进行分割,但由于棒材剪切工艺的限制,分割后二值图像中常出现孔洞和缝隙,从而影响了计数的准确性。
