查询词典 S-curve

The heaviest solid (iridium, density r s = 22.6g/cm3, size f 4mm) and liquid (mercury, density r s = 13.6g/cm3, size f 5×2mm ) on the earth is acoustically levitated by greatly enhancing both the levitation force and stability through optimizing the geometric parameters of the self-developed single-axis acoustic levitator.

1 After comparison of sum fusion and optimal fusion, sum fusion was selected as the fusion scheme for local test statistics. For the distributed CFAR detection based on the above three local statistics and sum fusion: CA-R-SUM and OS-R-SUM, CA-S- SUM and OS-S-SUM, Max-OS and Min-OS, Max-CA and Min-CA, their analytic expressions of detection performance were derived for and in nonhomogenous background.

2.1 通过求和融合与最优融合的性能对比，确定了以求和融合做为对局部检测统计量的融合方案；推导出了基于上述三种新的局部检测统计量和求和融合的分布式 CFAR 检测方案： CA-R-SUM 和 OS-R-SUM 、 CA-S-SUM 和 OS-S-SUM 以及 Max-OS 和 Min-OS 、 Max-CA 和 Min-CA 在、条件下在非均匀杂波背景中检测性能的解析表达式。
