visibility factor

Methods Forty-six cases were pided into several groups by the ways of anesthesia,age differences,courses and strabismus degree.

方法46例共同性内斜视患者按麻醉方式、年龄、病程、斜视度数分组,术前检查包括屈光状态、视力、斜视角测定和牵拉试验。

Sparse antenna array can reduce the hardware quannty in synthetic aperture imaging system greatly, but the visibility function samples don t distribute in a symmetrical grid.

可视度函数是空间频域的采样值,在做Fourier逆变换之前需要将样本点插到一个均匀的网格上。
