isobaric

When the air pressure in a region is lower than its surrounding , the feature is called a depression , a cyclone or an area of low pressure . in the northern ( southern ) hemisphere , the air around a depression moves in a counterclockwise ( clockwise ) direction ( looking from above ) . near the earth s surface , however , friction tends to cause the air to move slightly inward across the isobars 當地區的大氣壓力比其外圍低時,這個系統便稱為低氣壓或氣旋。在北(南)半球,低氣壓附近的空氣循逆時針(順時針)方向運行(從上面往下望) 。接近地球表面,摩擦力使空氣稍微向內越過等壓線。

Then applying the second development tool of autocad , visual lisp to scheme out the programs of plotting the network ' s systems drawing and the water isobar . consequently , the whole set design from the node outflow distributing to plotting the network ' s systems drawing and the water isobar is completed 然后應用autocad二次開發工具visuallisp編寫出繪制管網系統圖程序和繪制等水壓線圖程序,在autocad平臺上將平差或優化的結果快速成圖,從而完成從節點流量開始到管網優化直至繪出給水管網系統圖和等水壓線圖的一整套設計。

In addition , a new phenomenological eos is proposed along isobars that may be applied at high temperatures and high pressures for 16 alkali halide crystals , 6 minerals , and so on , by taking advantage of the hypothesis that anderson - griineisen parameter 5t is the function of volume ( v ) along isobars ) neisen ( _ r )參量與體積相對膨脹的唯象關系式得到一個可應用于相對高溫高壓下的等壓態方程,并對提出的固體物態方程進行了驗證、分析與討論。

Pressure readings measured at different weather stations ( after making corrections according to temperature etc . ) at the same time are plotted on a weather chart . meteorologists then draw lines to show places with the same pressure . these lines are called isobars 氣象人員把各地氣象站同一時間所量度到之氣壓值(根據溫度等作出適當的修正后)填上天氣圖上,然后將氣壓數值相同的地點用線連接起來,便成為等壓線。

In the theoretical framework of the relativistic mean field , the influences of ( superscript - ) meson condensate on the equation of state and the particle fractions of neutron star matter including delta isobars are studied 摘要在相對論平均場理論框架下研究了(上標- )介子凝聚對包括共振態的中子星物質狀態方程及其粒子分布的影響。

The examinations on the applicability and validity of the equations of state along isotherms and along isobars are made for alkali halides , alkali oxides , and some minerals 本文著重闡述了一些常用的具有廣泛的應用性的等溫態方程與等壓態方程,并對其有效性與可適性作了簡潔的分析與討論。

Also , everything else being equal , winds tend to blow harder ( gentler ) where isobars are closer together ( further apart ) 而在一般相同情況下,相鄰等壓線愈緊密(愈疏) ,風力也愈強(愈弱) 。

Near the earth s surface , however , friction tends to cause the air to move slightly outward across the isobars 接近地球表面,摩擦力使空氣稍微向外越過等壓線。

The atmosphere pressure gradient is an inverse measure of the spacing of the isobars on a weather map 氣壓梯度與天氣圖上等壓線的間隔大小成反比。

Measurement of these nuclei are often limited by interferences of isotopes and isobars 在測量這些核素時,通常存在同位素和同量異位素的干擾。

What is an isobar 什么是等壓線?

Isobars are useful in revealing the surface pressure pattern 等壓線能有效地顯示地面氣壓的分布狀況。

Isobars are usually drawn at 2 or 4 hpa intervals 等壓線一般以2或4百帕斯卡分隔。

Isobars can also be used to deduce wind conditions 等壓線也可用來推斷風的情況。

A region of low pressure with roughly concentric isobars is known technically as a cyclone . 具有大致同心的等壓線的低壓區在技術上稱為氣旋。
