双语例句
- Taking two dimensional divergence of gravity horizontal gradient field change, the long wave components of gravity changes can be effectively filtered out and the short wave components related more directly to earthquake preparation are kept and highlighted.
文中提出并应用场论理论中重力梯度场变化的二维散度可突出与地震有比较直接关系的孕震信息。 - The formula for Fraunhofer diffraction, which describes the diffraction pattern on an observing screen locating at the divergence center of an illuminating spherical wave and being parallel with the diffracting screen, is deduced from the Rayleigh-Sommerfeld formula of the scalar diffraction theory.
作者从标量衍射理论的瑞利&索末菲公式出发，导出了描述通过照明波发散中心并与衍射屏平行的观察面所接受到的衍射花样的夫朗和费衍射公式及其成立条件。 - It is obvious that the magnitude of divergence field is greater than that of vorticity and the allocation of these fields agree with the inertia-gravitational wave, so the occurrence of the spiral wave can be due to the instability of the inertia-gravitational wave.
失稳的螺旋波其散度场要较涡度场明显，物理量的配置也大体符合重力惯性波的情况，故可认为其是重力惯性波的不稳定所致。 - While for meridional ultra-long wave the vorticity equation has a divergence term. This result agrees with that of Matsuno who obtained the mixed Rossby-gravity wave in the dry tropical atmosphere.
但在经向超长波时，则涡度方程中存在辐散项，这一结果与Matsuno得到的在热带存在Rossby波和惯性-重力波混合的情况是一致的。 - Torsional divergence problem is an obstacle in the application of forward-swept wing aircraft, despite its many advantages in aerodynamic characteristics, such as high critical Mach number, low wave drag and no wingtip stalling.
