目的探讨间歇性外斜视患者手术前后近零视差、交叉视差及非交叉视差的临床变化规律。
Objective To understand the clinical variety of zero disparity, crossed disparity and uncrossed disparity in intermittent exotropia before and after strabismus surgery.
间歇性外斜视患者视差的损害顺序依次为非交叉视差、交叉视差、近零视差。
The sequential damage of stereopsis in intermittent exotropia is uncrossed disparity, crossed disparity and zero disparity.
由于这种类型的微带滤波器实现传输零点不需要通过滤波器非相邻谐振器间的交叉耦合来获得，因此，设计过程非常简单。
As this kind of microstrip hairpin filter does not require cross coupling between the non-adjacent resonators of the filter to obtain transmission zero, the design procedure of the filter is simple.
