cỗ máy này hoạt động trên nguyên tắc biến đổi dựa trên phản ứng hydro hóa. phân tử nước bị hydro hóa bởi cỗ máy và sau đó biến đổi.
water molecules are bombarded with microwave radiation which mutates their genetic recipe into any kind of food you want.
Điều đơn giản là... nó sử dụng năng lượng tập trung của khoảng 200 tia laser... hội tụ vào một mục tiêu kích thước bằng vài hạt gạo... chứa nhiên liệu hydro.
jake: the simple of it is, it's using the intense energy of some 200 laser beams focused on a single target the size of a few grains of rice filled with hydrogen fuel.
====Áp dựng mô hình phần tử hữu hạn====finite element programs are more flexible in design (triangular elements vs. the block elements most finite difference models use) and there are some programs available (sutra, a 2d or 3d density-dependent flow model by the usgs; hydrus, a commercial unsaturated flow model; feflow, a commercial modelling environment for subsurface flow, solute and heat transport processes; opengeosys, a scientific open-source project for thermo-hydro-mechanical-chemical (thmc) processes in porous and fractured media; and comsol multiphysics (femlab) a commercial general modelling environment), but they are still not as popular in with practicing hydrogeologists as modflow is.
