气球

Learn where to get a balloon ride, how balloons fly, how to become a balloon pilot, or find a balloon festival near you.

学习去哪里找一个气球坐，如何气球飞行，而如何成为一个热气球飞行员，或者找到一个热气球节在你附近。

A pilot found a balloon which seemed to fly toward a royal air force base neaby.he immediately reported it to the base but no one there could explain what happened on earth.the officer on the tower wa very mad when he got the news , because the balloon might be very dangerous to the planes.he said there maybe someone who was spying the base.

一个飞行员发现了一只气球，它像是正飞往附近的一个皇家空军基地。他马上把情况报告了该基地，但那里的人没有一个能解释这到底是怎么回事。控制塔上的官员得知这一消息后，非常气愤，因为气球有可能给飞机造成极大的危险。

As it opens, the pilot uses a propane burner to blow hot air into the envelope. The balloon then rises as it is inflated with the hot air until it is upright.

当气球充好气后，驾驶员会使用丙烷燃烧器将热气灌入气囊，当热空气渐渐增加，气球会慢慢的上升，到最后会完全竖立起来。

You will see there is dust in the board, using wind or Paper Tiger balloon blowing swab carefully, especially the panel into the annex and power outlet box in the vicinity, as well as the plug-in board positions, while the application of 台扇 hair to be blowing up a balloon blowing dust inside the chassis box to remove dust.

你会看到在板卡上有灰尘，用吹气球或者皮老虎细心地吹拭，特别是面板进风口的附件和电源盒的附近，以及板卡的插接部位，同时应用台扇吹风，以便将被吹气球吹起来的灰尘盒机箱内壁上的灰尘带走。

The apparent purposelessness of the balloon was vexing (as was the fact that it was "there" at all).

气球显而易见的无目的性使人恼火(这象气球偏偏要在"那儿"停留一样仗人恼火)。

Balloon to overpower the repulsive force between the negative ends of the water molecules and the balloon .

这是由于：水分子带正电荷的一端与气球之间的吸引力大于水分子带负电荷的一端与气球之间的斥力。

The main results are as follows:（1） the distance a sounding balloon drifts during operation is a lot longer than that is accepted as a horizontal resolution by present numerical models;（2） the positioning scheme presented for sounding balloons is basically applicable to a resolution of 10 km × 10 km;（3） on the whole, the position correction leads to the fact that the resulting analytic increment field is one order of magnitude smaller than the original;（4） analysis of the model predictions shows that soundings, when positioned,leveled soundingswould improve predictions.

结果表明：探空气球在施放过程中的漂移距离远远超过目前数值模式可取的水平分辨率；所设计的探空气球定位方案对水平分辨率为10km 10km的数值预报模式基本是可用的；总的来讲，位置订正对分析增量场的改变与原分析增量场相比小一个量级。模式预报结果显示，探空资料的定位使降水预报效果得到了改善。

The balloon is transversely stable because little force acts on the balloon in a direction perpendicular to the wind.

气球沿横向也是稳定的，这是因为在垂直风向的方向上几乎没有力作用于气球上。

So before men would go up in a balloon, they would first float a trial balloon without any men in it to test the situation.

所以，在人们上气球之前，他们都会先放上一个无人的试验气球来看看情况。

Objective To investigate the effects of interleukin-1 β converting enzyme gene on the biologic characteristics of ovarian cancer cells.

目的 探讨白细胞介素-1 β转换酶的表达，对卵巢癌细胞生物学特性的影响。

Campylobacter: This illness is the most commonly identified cause of diarrheal illness in the world.
