There was cis-trans isomerism on the system of SSBR/S/NS and the degree of cis-trans isomerism.

SSBR/S/NS 体系存在顺反异构现象，顺反异构程度也存在。

A rather more complex case is that of steric isomerism.

更复杂的情形是立体异构问题。

Objective: To evaluate the value of MRI in the patients with atrial isomerism.

目的：评价磁共振成像在心房异构中的应用价值。

The team "stereoisomerism" however, is generally restricted to mirror image isomerism.

然而“立体异构”一词通常只限于镜象异构。

Objective to study the diagnostic significance of computed tomography (ct) in atrial isomerism.

目的研究心房异构的病理表现，探讨CT在心房异构诊断中的作用。
