For the first few thousand feet above sea level the rate of pressure decrease is in the neighbourhood of 1 inch of pressure for each 900 to 1000 ft
在離海面幾千英尺高度上（在拔海高度數千英尺以下）氣壓遞減率大約是每900到1000英尺高度下降1英寸汞柱左右。The bandwidth of a copper wire decreases exponentially with length, and hence adsl data rates drop by 10x in going from 6000 feet to 18000 feet
答案:在銅線上頻率是隨著長度以陪數遞減，所以adsl的數據傳輸率從6000尺至18000尺是以10陪下跌。Detailed diagnoses is made on a heavy - hard rain in the northeast qinghai - xizang plateau using ncep data of 1 x 1 with 6h intervals, more complete and integrated conventional observational data and the data set of automatic meteorological stations in plateau and new generation doppler radar data and satellite images and etc. the following conclusions can be drawn : 1. the distribution of heavy - hard rain, which is characteristics of valley topography in northeast qinghai - xizang plateau is obviously effected by topography. the distribution of yearly mean precipitation and the frequencies of heavy - hard rain in this area are descending from east to west
本文首先利用ncep時間間隔為6小時的1 1的格點資料、更全面、更為完整的常規探測資料和高原地區布設的自動氣象站資料、新一代多卜勒天氣雷達資料、衛星雲圖資料等對高原東北部地區大到暴雨的天氣、氣候特徵及大尺度環流背景進行分析，形成對高原暴雨的整體認識，並為以後的數值模擬提供大尺度環流背景及依據，分析中發現： 1 、高原東北部地區大到暴雨的分佈明顯受到地形影響，年降水量和大到暴雨次數自東向西呈階梯性遞減趨勢，分別在高原東北部的外流河谷地區和四川北部地區存在大值中心。It is brought forward for the first time that in summertime the pco2 of the surface water near the changjiang estuary, whose salinity is less than 20, decreases dramatically from upwards of 800uatm to downwards of 300uatm within the range of less than half one latitude, suggesting a transformation of a strong co2 source to a co2 sink in a finite space
首次調查得到，夏季長江口附近鹽度20區域的水體極高的pco _ 2 （最高測得800 atm以上）在不到半個緯度的范圍內遞減到300 atm以下，即由一個很強的大氣co _ 2源，有限的空間尺度范圍內變成為匯區，有著極大的梯度變化。分享友人
