椭圆性 meaning in English
ellipticalness
Examples
- The ellipticity of the elliptic
椭圆薄膜的椭圆性 - Under the assumption that the elastic tensor satisfies the strong - ellipticity condition , we reduce the two - dimensional equations of linearly elastic membrane shells to a first order linearly symmetric hyperbolic system
摘要在弹性张量满足强椭圆性条件的假设下，把2 -维线性动态膜壳方程组化为一阶线性对称双曲组。 - Therefore , for 980nm pumping , a significant disadvantage is the low coupling efficiency to the single mode fiber because of the mold field mismatch between the elliptical laser beam and the circularly symmetrical fiber mode and also because of the phase mismatch
但是对于像980nm泵浦激光器发出的激光来说，由于特殊的物理结构，使得激光光束具有高度的椭圆性。对于椭圆度高的激光光束和单模光纤耦合的报道不是很多。
