The parametric design of hydropneumatic recuperator base d on the secondary development of AutoCAD using visual basic6.0 is presented aim ing at the problems in the traditional design method of recuperator, such as com plexity of design process, long design cycle and low design efficiency.

针对传统火炮液体气压式复进机的结构设计中存在的过程复杂、设计周期长\，效率低，且传统的复进机的设计方法也无法满足现代加工方法的数控化、智能化的发展趋势，通过 Visual Basic 6.0 编程对 AutoCAD 2006 进行二次开发。

Eta Carinae, a star between 100 and 150 more massive than the Sun, is near a point of unstable equilibrium where the star's gravity is almost balanced by the outward pressure of the intense radiation generated in the nuclear furnace.

Eta Carinae，质量是太阳的100到150倍，这是一个不稳定平衡的临界点，也就是恒星的引力通常靠核反应堆所产生的强烈辐射制造的外层气压来平衡的。

With different explicit schemes , the simulations reveal different results of the minimum central pressure , the maximum surface winds , the updrafts of eye wall and microphysical fields .

然而不同的显式过程模拟的的云物理量场不尽相同，引起不同的潜热释放，模拟的动力场，台风眼半径，台风壁上升气流强度，台风眼最低气压和地面最大风速等存在明显的差别。

In addition, the computational evaluations indicate that the heat transfer enhancement of delta winglet for aligned tube bank heat exchanger is more significant than that for staggered tube bank heat exchanger, the heat transfer enhancement of delta winglet with the attack angle of 45° is more obvious than that of 30°; the delta winglet with the attack angle of 45° leads to an increase in pressure drop, while the delta winglet with the attack angle of 30° results in a slight decrease.

另外计算还发现：三角形小翼对顺排换热器的强化换热效果好于对叉排换热器的强化；冲角为45°的三角形小翼强化换热效果好于冲角为30°的三角形小翼；冲角为45°的三角形小翼导致空气压降提高，而冲角为30°的三角形小翼则可使压降有所减小。

Also captured here floating just below the Moon is a thin, red mirage -- in this case, an atmospherically magnified and distorted image of the red rim.

在这张图片中气压导致的放大的扭曲的红色轮廓，是图片中月亮的底部飘浮着的是一层薄薄的红色的雾气。

Bucketing toward Manhattan in a yellow cab, my ears buzzing from pressurization, my eyes scratchy from dry air at thirty thousand feet, my nerves twitchy from lack of sleep, filled with that false optimism which is a by-product of adrenaline, I was not only sure Constance was near, I felt she awaited me.

坐在黄色计程车中一路向曼哈顿颠簸而去，我的耳朵由于高空气压而嗡嗡作响，我的双眼由于三万英尺高空的干燥空气而刺痒难当，我的神经由于缺少睡眠而不停抽搐。肾上腺素的分泌让我有种不真实的乐观感。我很肯定Constance不仅离我很近，而且她还等着我呢。

On the other hand, through the discussion on coronal density of flares, we found that the column mass density at the top of chromospheric flare model can not be represented the total mass above the chromosphere and the coronal density can be estimated from presure balance based on semiempirical model. Through estimations, the results show that the total mass above the chromosphere is about the same as the mass between the top of chromosphere and electron source, which so give an evidence that the source of electrons is situated at the top of flare loop.

另一方面，通过对日冕物质密度的讨论发现，半经验模型中色球顶部柱数密度不能用来代表耀斑环在日冕内的总物质，日冕物质密度可用日冕气压与半经验模型中色球顶部压力近似相等来进行估计，进而发现耀斑环在日冕内的总物质与前面估计的色球顶部到非热电子源之间的总物质近似相等，结果趋向于支持非热电子源位于环的顶部。
