[Effects of brackish water irrigation on grain quality characteristics and yield of winter wheat].

Brackish water resource is widely distributed in the North China Plain, which has not been effectively utilized. Using brackish water for irrigation can alleviate water resource conflict in the well-irrigated area and solve the problem of groundwater over-exploitation of the North China Plain. A long-term experiment (since 2006) was conducted to investigate the effects of brackish water irrigation on the quality and yield of winter wheat in the North China Plain.

[Study and design of the Q-switched Nd:YAG laser control system based on S3C2410].

This paper presents a design of the control system for the Q-switched Nd:YAG laser, which is based on S3C2410, and the emphasis is laid on its hardware & software's design. The LCD interface with the function of a touch screen is implemented by the Qt/Embedded graphical interface application programs.
