| 摘要: |
| 建立了海洋表层气泡运动和半径变化的数学模型，通过计算发现一定深度的气泡存在一个临界半径；在一定初始深度气泡的半径小于临界半径时不能到达水面，随着时间的增长，气泡半径逐渐变小，直至最终溶解；气泡的半径大于临界半径时，气泡随着时间的增长，半径逐渐增大，直至达到水面破碎；气泡的初始深度不同，其临界半径也不同；半径在临界点附近的气泡的存活时间最长。对海洋表层气泡运动规律的研究对了解海洋表层气泡的分布规律有重要意义。 |

| Abstract: |
| The bubble in ocean surface has an important effect on heat transfer and gas-water exchange between ocean surface and atmosphere, and the study on the motion of bubble near the ocean surface has a great significance. The mathematics model of the kinetic characteristic and the radius change of bubble near ocean surface are set up. A critical radiues for bubble at a certain initial depth is founded by calculation. In a certain initial depth, the bubbles whose radiues less than the critical value, will diminished and dissolved with time. When the radius of bubble is larger than the critical value, the bubbles will augment until they reach the ocean surface. The critical radius is different if the initial depth of bubble is different. The bubbles’ lives, whose radiuses are near the critical value, are the longest among all the bubbles. |
