查询词典 migration

The extracted P-wave is reverse-time extrapolated and imaged with a P-velocity model using a finite difference solution of the scalar wave equation, the extracted S-wave is reverse-time extrapolated and imaged similarly, but with an S-velocity model, and converted S-wave data requires a polarity correction prior to migration to ensure constructive interference between data from adjacent source.

More specifically, we describe our solution for securing credential migration that we're developing for productization.

更具体地说，我们描述我们的解决方案，为确保认证移民，我们正在发展为产品化。

With aggravation of global environmental problems, environmental migration has been a critical issue for many state governments and the whole world.

随着全球环境问题的加剧，环境移民问题正日益受到世界各国政府和国际社会的高度重视。

The large waves of migration of the modern world, along with the instant technology we've devised (television, radio, movies, the Internet), encourage verbal cross-fertilization.
