isobar 是什么意思

	n. 1.【气象学】等压线。 2.【化学】同量异位素。

(meteorology)an isogram connecting points having equal barometric pressure at a given time

	1.	Pressure differences are indicated on weather maps by isobars . 在气象图上气压差用等压线表示。
	2.	A region of low pressure with roughly concentric isobars is known technically as a cyclone . 具有大致同心的等压线的低压区在技术上称为气旋。
	3.	Isobars can also be used to deduce wind conditions 等压线也可用来推断风的情况。
	4.	Isobars can also be used to deduce wind conditions 等压线也可用来推断风的情况。
	5.	Isobars are usually drawn at 2 or 4 hpa intervals 等压线一般以2或4百帕斯卡分隔。
	6.	Isobars are useful in revealing the surface pressure pattern 等压线能有效地显示地面气压的分布状况。
	7.	What is an isobar 什么是等压线？
	8.	Measurement of these nuclei are often limited by interferences of isotopes and isobars 在测量这些核素时，通常存在同位素和同量异位素的干扰。
	9.	The atmosphere pressure gradient is an inverse measure of the spacing of the isobars on a weather map 气压梯度与天气图上等压线的间隔大小成反比。
	10.	Near the earth s surface , however , friction tends to cause the air to move slightly inward across the isobars 接近地球表面，摩擦力使空气稍微向内越过等压线。
