中文拼音 [qìyāqīngxiàng]
氣壓傾向
英文
barometric characteristic-
Second, different pressure levels are represented by nearly horizontal lines on the tephigram while constant temperature levels are straight lines tilted at 45 degrees from the vertical figure 3
第二，在溫熵圖上多條接近水平的線為代表不同氣壓的等壓線，而向右傾斜45度的直線則為等溫線圖三。Through analysis of potential vorticity in isobaric surface field, in low - troposphere a positive potential vorticity disturbance exist and form incline disturbance column northward before rainstorm generation, at the same time have also reflected positive potential vorticity disturbance for severe convection weather trigger role in lower - troposphere ; soon positive potential vorticity disturbance in high - troposphere downward, form one vertical disturbance column, now corresponding precipitation develop stage ; in the prosperous stage of rainstorm that maintains isolines of horizontal distribution and still have straight positive potential vorticity disturbance in 600 - 700 hpa isobaric surface field ; when near ground arises negative potential vorticity disturbance, precipitation also weaken
通過對等壓面的位渦分析，發現了在暴雨發生前，在對流層低層有正位渦擾動存在並向北形成傾斜的擾動柱，同時也反映了對流層低層正位渦擾動對強對流天氣的觸發作用；隨后高層正位渦向下擾動，形成一個垂直擾動柱，這時對應降水的發展階段：在暴雨的鼎盛階段， 600 700hpa上空維持水平分佈的等值線，在其上還有正的位渦擾動；當近地面出現負的位渦擾動時，降水隨之也減弱。The paper mainly discussed the reasons of stress from liquid ammonia pressure vessel causing crack through examing data and experimental results and analysing relevant referential documents and materials, taking 1200 ammonia vessel ' s crack and leaking in a certain fertilization company as an example : there existed remaining welding, stress in the equipment ; there existed a stress decaying surrounding, i. e., moisture 0. 2 %, and temperature > - 5 with o2 or co2 inside ; the higher the intensity of raw materials, more possible it was to have stress decaying crack
摘要以某化肥公司1200氨冷器殼體開裂泄漏的失效分析為例，通過對檢驗數據和結果及有關文獻資料的分析研究，探究了液氨介質壓力容器產生應力腐蝕裂紋的原因：設備中存在較高的焊接殘余應力；液氨介質具備應力腐蝕環境，即含水量0 . 2 % ，且有空氣（ o2或co2 ）污染（或摻入） ，使用溫度高於零下5 ；母材強度越高，應力腐蝕裂紋產生的傾向就越大。A hybrid of pressure and terrain - following vertical co - ordinates is used in which the upper levels tend towards the pressure coordinate and near - surface layers tend towards the terrain - following coordinate
垂直坐標是混合了氣壓坐標和依隨地形變化的坐標，上層傾向氣壓坐標，接近地面的層次則傾向依隨地形變化的坐標Second, different pressure levels are represented by nearly horizontal lines on the tephigram while constant temperature levels are straight lines tilted at 45 degrees from the vertical ( figure 3 )
第二，在溫熵圖上多條接近水平的線為代表不同氣壓的等壓線，而向右傾斜45度的直線則為等溫線（圖三） 。分享友人
