Controlling emitter clogging by reducing clogging substances is commonly used nowadays, but it is merely applied in clogged emitters, so establishing a convenient and pre‐treated emitter clogging control strategy is essential. In this paper, four types of non‐pressure‐compensating emitters were selected for a drip irrigation experiment using reclaimed water. Furthermore, suspended particles' components...
Response effect assessment of Internet public opinion is a very important aspect of Internet public opinion response. It can summarize the response and handling works of public opinion and make it clear to the advantages and disadvantages during the process, and then provide guidance to future work. This paper presents assessment program for response effect of Internet public opinion used AHP and...
A labyrinth path is the predominant pattern for drip irrigation emitters at present. It is very important to explore the pressure loss mechanism for the labyrinth path. This paper took the Minkowski fractal curve flow path, a special labyrinth flow path, as an object to study the pressure loss mechanism of fractal flow paths with dimension analysis technology and rough pipe turbulence theory. The...
