The flame consists of two zones: an entrainment zone attached to the burner and a mixing and combustion zone on top of it.
此处，火焰包括两个区域，一个是位于喷口附近的输入区，一个是上部的混合、燃烧区。Freshness of the product may be extended after opening with the addition of a press-to-close zipper, slider-zipper, or spout.
产品的生气勃勃也许是延长的在打开增加按对之后关闭拉链、滑子拉链，或喷口。A complicating factor is uncertainty surrounding the choice of axisymmetric exhaust nozzle geometry and ventral strakes in the long term.
轴对称排气喷口的几何形状以及腹鳍边条周围环境的不确定性是一个复杂的因素。Meinstein said the harbor is the caldera of a volcano.
迈尔斯泰恩说，港口是火山的一个喷口。The PE sets, two identical ones were included, the long ladder like railings are for the long ballast vents on the sub.
该PE套，两个相同的人包括在内，长期的阶梯一样，栏杆是为长远镇流器喷口该小组。These vents are known as black smokers for the plumes of dark hydrogen sulfide they belch into the ocean.
这些喷口因为向海洋喷射出黑色的硫化氢热柱而被称为黑烟囱。Giant tube worms, crabs, and shrimp live in the dark, a mile below the ocean surface, huddled around superheated geothermal vents.
巨型管蠕虫，螃蟹和小虾生活在海洋表面以下一英里的黑暗之中，挤在海底灼热的地热喷口附近。To the surprise of many scientists, however, the risk mining poses to the vent communities may be smaller than originally feared.
然而，让许多科学家吃惊的是，矿物开采对热泉喷口附近的生物群所造成的威胁或许不及最初预想的那样大。As the structural shape of the gaps between nozzle petals is not known at this time, we modelled the open nozzle as simple cylinder.
喷口菊蕊之间缝隙的结构形状还不清楚，我们把打开的喷口设计成了简单的圆柱体。
