窄隙 meaning in English

narrow gap
narrow space

We find that the relations between the electronic effective mass of lowest - lying conduction band and wave vector are resemble , not only for narrow - gap semiconductor zigzag tubes but also for wide - gap semiconductor zigzag tubes . the electronic effective masses at bottom of lowest - lying conduction band depend on their tube - diameters
我们发现，无论是锯齿型窄隙半导体管还是锯齿型宽隙半导体管，同一类管的最低导带的电子有效质量随波矢变化的规律基本相同，且其导带底的电子有效质量随管径的增大而减小。
Again , the electronic effective masses at bottom of lowest - lying conduction band of narrow - gap semiconductor zigzag tubes are inversely proportional to square of their tube - diameters . as for chiral tubes , the electronic effective masses at bottom of lowest - lying conduction band contact with their tube - diameters and chiralities
此外，锯齿型窄隙半导体管导带底的电子有效质量与其管径的平方成反比关系；对于螺旋型管，其导带底的电子有效质量不仅与管径相关，而且与螺旋度也相关联。
