英语翻译
Uniformity coefficient values are determined by catching discharge from sprinklers in evenly spaced cans and evaluating the catchment mathematically.One mathematical description widely used was developed by J.E.Christiansen,who called his value the uniformity or CU.The coefficient is expressed as a percentage and is dependent on rotation uniformity,speed of rotation (for rotary type sprinklers),geometric layout pattern,nozzle pressure,and spacing distance.Christiansen’s uniformity is determined by the following:
CU=100（1.0-(∑x)/mn）
Where CU=Uniformity coefficient in percent
x=Difference between individual catchment and the mean catchment
m=Mean catchment
n=Number of catchments
Values of 80% are considered minimum for field crops and turfs,and 85% for closely spaced,high-value crops.Closer spacings generally result in higher CU values.
有点难度...希望达人们能帮忙看看...公式本身就不用翻译了.....

一种被广泛使用的数学描述是由J.E.Christiansen所建立,他将此系数值
称为匀细度,简称为CU.
The coefficient is expressed as a percentage and is dependent on rotation uniformity,speed of rotation (for rotary type sprinklers),geometric layout pattern,nozzle pressure,and spacing distance.
此系数是一个百分数,它取决于转动的均匀性、转动速率(对旋转型喷灌器而言)、立体结构、喷嘴压强和间距.
Christiansen’s uniformity is determined by the following:
CU=100（1.0-(∑x)/mn）
Where CU=Uniformity coefficient in percent
x=Difference between individual catchment and the mean catchment
m=Mean catchment
n=Number of catchments
x=Difference between individual catchment and the mean catchment
单独俘获量与平均俘获量之差
Values of 80% are considered minimum for field crops and turfs,and 85% for closely spaced,high-value crops.Closer spacings generally result in higher CU values.
80%被视为对野生农作物的最低值；
85%被视为密植、高产的农作物；
密植型通常导致较高的CU值.
不好意思,没有专门搞过喷灌技术,以上翻译,仅供参考.惭愧.

均匀系数值是由匀距离分布的罐中得到的喷水器的喷射的水量以及对其进行数学估算来决定。
一种广泛使用的数学描述是J.E.Christiansen建立的，他称此数值为均匀度，简写为CU。
此系数表达为一个百分数，它取决于转动的均匀性、转动速率(对旋转型喷灌器而言)、几何结构、喷嘴压强和间距。
CU由下面公式得出：CU=100（1.0-(∑x)/mn）
这里：CU --- 百分数表达的均匀系数。
x --- 单个得水量和平均得水量之差
m --- 平均得水量
n --- 得水的罐数
80%的均匀系数被认为是地里作物和草坪的最低要求，85%用于密植的，高价值的作物。一般来说，密度较大导致高的CU 值。
