temperature gradient造句
1. Palaeoclimate reconstructions indicate that the meridional temperature gradients decrease, and poleward heat flow increases, as global mean temperature increases. 2. The temperature gradient just above the core would become much steeper, for example, causing a much hotter boundary layer. 3. It is the steep temperature gradient that makes it possible for us to work black smokers with a large measure of safety. 4. This temperature gradient may be vital to successful hatching. 5. III The results demonstrate that the calculated temperature gradient is similar with the value evaluated by constituent supercooling theory. 6. On the contrary, if temperature gradient is relatively low, combustor only undergo low compressive stress at high temperature. The combustor of engine has a longer life length. 7. Examples of interactions are mass transfer caused by temperature gradient. 8. It is a history of improved temperature gradient and promoted cooling rate from the aspect of unidirectional solidification technology evolution. 9. The temperature gradient in front of S/L interface was measured on Zone Melting Liquid Metal Cooling(ZMLMC) directional solidification apparatus. 10. An eigenmode equation of ion temperature gradient driven instability in a tokamak plasma with negative magnetic shear is solved numerically by the shooting method. 11. The results show that temperature gradient has great impact on ESD. 12. LBO glass ceramics were prepared by temperature gradient method, its TSEE(thermally stimulated outer electron emit) performance have been researched. 13. The effects of temperature gradient and interfacial growth velocity on solid-liquid interface morphology were studied with succinonitrile under the unidirectional solidification system. 14. The Fraunhofer device depends on a temperature gradient: the greater the gradient, the more electricity generated. 15. The Late Mesozoic characterized by higher temperature gradient is main period of gas generation and migration of Paleozoic coal series and carbonates. 16. If the material is a poor conductor, as most polymers are, temperature gradients inescapably exist and heat will therefore flow. 17. The high-temperature region locates below the roof and the temperature gradient out of the combustion area is not obvious. 18. By theoretical calculation, it is found that the same earth temperature gradient leads to the greater difference of temperature stress in different kind of rocks. 19. The simulation result shows that the dynamic pressure amplitude was amplified obviously when the temperature gradient was above the critical value. 20. The simulation results show that when preheated air temperature increases the maximum temperature gets larger, the temperature gradient becomes lower and the flame length longer. 21. The microstructure characteristics and microsegregation of DD2 single crystal have been studied under ultra-high temperature gradient and rapid solidification conditions by laser rapid remelting. 22. Some rules of computer numerical simulation for the directional solidification with steep temperature gradient have been found out. 23. The method suits for spelter smelt and other metal smelting Methods: That need high - temperature - temperature gradient operation. 24. Balling, which occurs at the end of the scanning line, is caused by the dissymmetric temperature field and the great temperature gradient. 25. The heat transferred per unit area and unit time ( flux ) is proportional to the temperature gradient. 26. A technology of propane deasphalting which depends on the heat of feed itself to form a temperature gradient needed for extraction is introduced together with its application in production. 27.
