four-dimensional造句
1. Why space-time should be four-dimensional is a question that is normally considered to be outside the realm of physics. 2. Up verification code requires four-dimensional calculation. 3. Four-dimensional, professional manufacture and provision of sanitary. 4. But you can conceptualize a four-dimensional data structure by thinking of the fourth dimension as multiple three-dimensional cubes. 5. Numerical simulations are performed by using the original four-dimensional equation to confirm the analytical results. Some global behavior of the system is also investigated numerically. 6. Four-dimensional electron micro-scopy produces "movies" of nanoscale processes occurring over time intervals as short as femtoseconds (10–15 second). 7. A four-dimensional IA model was studied in this paper, which includes IA object dimension, IA capability dimension, IA countermeasure dimension and IA time dimension. 8. Your baby's four-dimensional dynamic video we will you save a month[/four-dimensional.html], and row of medical information will furnish photographs kept for over 3 years. 9. Representation of four-dimensional vectors. 10. Similarly, other faults entropy points in four-dimensional space can be gotten. 11. The forced vibration of pendulum is described by four-dimensional phase space and the fourth order autonomous ordinary differential equation. 12. Four-dimensional point groups are deduced by generating normal three-dimensional point groups with certain restrictions which are unique for modulated structures. 13. Objective: To assess the value of four-dimensional ultrasound in the diagnosis of surface deformity in fetus. 14. The four-dimensional data assimilation is to integrate the current and past data into a forecast model equation for providing time continuity and dynamic coupling. 15. His fundamental new idea was that space and time had to be considered together as a single entity: a four-dimensional spacetime. 16. The kinematics of free electrons is described by the free Dirac equation, a four-dimensional system of partial differential equations. 17. Did this spacetime really behave on large distances like a four-dimensional, extended object and not like a crumpled ball or polymer? 18. Secondly, we investigate the energy density produced by a state vector which is the superposition of three single electron states in the Dirac field in the four-dimensional Minkowski spacetime. 19. That was encouraging but not yet the same as showing that these rules are enough to stabilize a full four-dimensional universe. 20. Furthermore, the conventional observations are done in the MM5 model system, and a four-dimensional variational data assimilation test is made based on observed data. 21.
