喷灌

In this paper, effects of the statement index on design volume of an air chamber are analyzed theoretically.

恒压喷灌系统调压罐空气状态变化多变指数是系统设计的重要参数。

The result indicated that: land leveling in chernozem area should be based on the actual mode of production and soil characteristics to amend the local topographic surface; water conservancy works of farmland should adopt sprinkler irrigation system to save water; field road design requires to be based on field conditions in order to maximize conservation of the farmland; creating a shelter to mitigate the harmful wind, focusing on raising soil fertility, and changing tillage methods to improve soil.

研究结果：黑钙土地区土地平整应依据实际生产方式与土壤特性采取修改局部地形面方法；农田水利设施需采用喷灌系统进行节水灌溉；田间道路设计须根据实地条件与生产方式最大限度节约耕地；营造防护林以减缓有害风；注重培肥地力、改变耕作方式以改良土壤。

In the experiments the seasonal averaged Christiansen irrigation uniformity coefficient varied from 72% to 84%.

试验中生育期平均喷灌均匀系数变化范围为72%～84%。

Overlapped sprinkler water distributions were tested to determine the relationship between Distribution Uniformity and Christiansen Uniformity Coefficient.

利用多喷头组合喷洒试验研究了分布均匀系数DU 与喷灌均匀系数CU 之间的关系。

Crown rot can kill trees damaged by frost or growing in saturated soil, as well as from trunks hit by frequent, superficial lawn sprinkling.

冠腐病，可以杀死树木损坏或霜冻曰趋饱和土中，以及从树干击中频繁，浅表草坪喷灌。

Reducing the operating pressure of sprinkler system is one of the major energy -saving methods.

降低喷灌系统工作压力是节能的主要方法之一，而喷头的工作压力与喷灌系统工作压力紧密相关。

In precision controlling, the closed loop negative feed back technology is used, and the circumrotation corner velocity ω of water pump is adjusted by examining the range of spraying irrigation , and the hydraulic pressure is adjusted, then accurate jet radii r is obtained finally.

为了实现喷灌精度的控制，采用了负反馈闭环控制技术，通过对喷射距离L检测来调节水泵转速ω以改变水压Pi最终获得较精确的喷射半径ri或喷灌域。

These formulae can be used to establish the hydraulic gradient lines of laterals easily.Thus, alternate measures for bettering the hydraulic gradient lines may then be a...

这类支管，加密喷头，喷灌的就向滴灌的接近，加密滴头，滴灌的就向渗灌的接近，型类有异，原理则同，本文只就渗灌、喷灌两类各作简论。

This paper describes principally the computation method which can be applied for drawing the performance curves of the tested pump and a family of isopleths of the sprinkling strength of the sprinkler head, and also points out some problems to be noticed in program design.

本文主要描述了用PS—80微型计算机绘制水泵性能曲线及喷头喷灌强度的等值线的算法，同时指出在程序设计中应注意的问题。以2BPZ—35自吸喷灌泵及PY20A喷咀直径φ7×4喷头为例，分别在PS—80微机上运行这两个程序，计算的结果和绘出的曲线能符合试验单位的需求。

If the irrigation system is still operating, the sprinklers will continue to operate, emptying the irrigation system.

如果喷灌系统还在运行，喷头还会继续工作，排空喷灌系统。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
