difference space
1.bsn and △Fk2 in this region are more obvious, especially, the difference in space distributions of the local statistical information and secular variations, the former trends chiefly east-west while the latter north-south.
2.The application of elastic mechanics in launch vehicle technology perfects flight theory. The application of elastic mechanics and two-phase flow theory suppresses POGO. Considering the difference between space and earth, the stress of mechanics is transferred from gravity to molecular force, and the application of two-phase flow and three-phase flow theory resolves key technical problems in engine restart.
3.The commonly used migration methods include split step Fourier (SSF), Fourier finite difference (FFD), frequency space domain finite difference (FXFD), and generalized screen (GS).
4.Fourth, the distortions in micro stereovision system are analyzed, and three kinds ofdistortions, the rotation of CCD image planes, the depth difference in object space of SLM, the distortions of an optical system, are considered mainly.
5.While two (or more) electromagnetic waves of the same frequency, same direction of vibration, same phase or constant phase difference superpose in space, the amplitude of composite wave is vector sum of the amplitude of each wave.
6.Despite the difference in time and space, both statements smack of nationalism, sounding similar on both occasions.
8.Finite difference method in frequency-space domain caus-es convenient operation, good stability and satisfactory adaptability to vertical andlateral velocity variations; however it results in poor image accuracy and slow oper-ation.
9.Sets up three-dimensional movement modal of towed-cable, the vector dynamic equilibrium equation is expanded under local coordinate, and numerically discreted by central difference on time and space through transforming Eular angle.
10.The concept of potential difference is still of practical importance to the space where eddy electric field exists.
