摘要
采用均匀网格定点实测大气降尘资料,然后把全市区纳入一个平面直角坐标系,查算各监测点坐标;连结这些点成三角形,求算这些点的趋势坐标及降尘值,最后计算大气降尘量。根据使三角形相等或接近相等的原则,采用其他连接法,所得结果没有明显差异。
Adopting even fixed position for monitoring atmospheric dust depostion and taking the whole urban district as a right angle coordinate system, then measuring the coordinate of every monitoring spot. Connecting every spot to form a triangle, and calculated trend coordinate and deposition value of the spots, finally calculated atmospheric dust deposition. Based on the principle of being equal triangle or colesly equal triangle and other connecting method, the result was not obvious difference.
