仿真结果表明在子阵叠加结构中,除了在子阵级和单元级使用加权分布降低副瓣电平外,子阵叠加比决定了阵列的副瓣性能。
The results point out that the fingerprint spectrum, overlap ratio and eight strong peaks are different from each other in various species of the same genus.

Good sidelobe performance can be achieved over wideband when subarray overlap ratio equals 2 and Taylor weight distribution is used at element and subarray stage.
当在子阵级和单元级使用泰勒分布,并且子阵叠加比为2时,工作在宽带、宽角下的阵列可以获得较好的副瓣性能。
Experimental results show that the material remove rate(MRR) increases with the increase of laminated depth and decreases with the increase of tool path overlap ratio.
研究结果表明工件的加工速度随着分层厚度的增加而增加,随着轨迹重叠率的增加而减小;
If the coefficient of engagement overlap decreases, the flow aggrandize, trapping volume and the flow pulsating ratio decreases.

在计算机视觉与图像处理领域,"overlap ratio"(重叠率)是衡量两个区域空间重合程度的重要量化指标。该术语最常见的应用场景是目标检测任务中的交并比(Intersection over Union,IoU)计算,其数学表达式为:
$$ text{IoU} = frac{text{Area of Overlap}}{text{Area of Union}} = frac{A cap B}{A cup B} $$
其中A和B分别代表预测框与真实标注框的区域范围。根据国际计算机视觉会议(ICCV)的算法评估标准,当IoU值≥0.5时,通常判定为有效检测。在医学图像分割领域,美国国立卫生研究院(NIH)的研究报告指出,重叠率指标还被扩展为Dice系数,其公式表达为:
$$ text{Dice} = frac{2|A cap B|}{|A| + |B|} $$
这两种计算方法都通过量化分析重叠区域与整体区域的比例关系,为算法性能评估提供客观度量标准。英国皇家工程院的技术白皮书特别强调,在自动驾驶系统的障碍物识别模块中,重叠率参数的优化直接影响着系统对车辆、行人等目标的定位精度。
overlap ratio 是一个技术术语,通常指两个或多个物体、区域或现象在空间、时间、功能等方面的重叠程度与整体之间的比例关系。以下是详细解释:
在工程领域,overlap ratio 的计算可能涉及以下公式: $$ text{Overlap Ratio} = frac{text{重叠部分长度/面积}}{text{总长度/面积}} $$
如需更具体的领域应用(如机械设计参数),建议参考专业文献或工程手册。
