在正常的用具有阳性折射指数制作的多个光导纤维中，这种情况会让电缆的有效厚度高于它的实际物理厚度。
In normal optical fibres made from materials with positive refractive indices, this makes the effective thickness of the cable greater than its physical thickness.
同时观察记录患者的一般资料、体质量指数等，并用阳性及阴性症状量表(PANSS)评定患者的临床症状。
General information and body mass index (BMI) of the patients were recorded, and the clinical symptoms were assessed with the positive and negative symptom scale (PANSS).
标记指数(LI)为阳性细胞率，检测了活检与外科手术之间CDK4 LI变化与生存之间的关系。
Labeling index (li) was presented by the percentage of positive cells, and change of CDK4 li between biopsy and surgical operations was examined for association with survival.
