滴灌系统 meaning in English
driirrigation system
Examples
- Emitters are one of the key parts of drip irrigation system . thus , the study on the hydraulic performance and anti - clogging ability of emitters has important significance
滴头是滴灌系统最为关键的部件之一，因此，对滴头水力性能和抗堵塞性能的研究有着极为重要的意义。 - Trickle irrigation is regarded as a significant technology of water - saving irrigation , because we can exactly control the quantity of irrigation water , decreasing ground evaporation and deep - seated leak
滴灌系统作为一种优秀的节水灌溉技术，它能够精确的控制灌溉水量，减少地面蒸发和深层渗漏。 - When the area of little irrigation district is constant , drip line of trickle irrigation has the optimizing length . if the length of drip line is longer or shorter than the optimizing length , the expense of trickle system increases
一般认为，毛管长度越长，则滴灌系统造价相应就会减少，因此，在优化设计时，通常认为毛管取最大长度。 - Therefore , we can exactly gain the average flux of emitters in little irrigation district by determining the average flux of emitters in these positions instead of determining all emitters within little irrigation district
测定此范围内毛管上灌水器的平均流量，就可以得出灌水小区的平均灌溉水量，为精确测定滴灌系统平均灌溉水量提供简便途径。 - The length of drip line is an important parameter of optimum design . it has direct effect on the price and quality of trickle system . traditionally , the cost of drip system diminishes as the length of drip line increases
在滴灌系统的田间工程中，毛管的长度是滴灌系统优化设计时的一个重要参数，它不仅影响滴灌系统的造价，而且还影响到滴灌系统的灌水均匀度。
