Effects of ridge planting and convention planting on the quality of spring wheat were studied.

The contrast trial between ridge planting and convention planting pattern and the trial of effect on spring wheat quality and yield of different fertilizer and seeding rates in ridge planting were carride out in MiShan city trial field during 2006-2007.

the relationship of parallel operations of excavation and bolting integration is researched.

However, in order to decrease the construction time as much as possible, this paper put forword a parallel operation method in which the above three steps can be done simultaneously.

The paper introduces the construction technology of adopting artificial and mechanical shaft sinking as well as a parallel operations in concrete pouring construction with whole sliding-mode to replace the traditional way of the sole artificial construction in the past,thus realizing improvement of rapid construction craft.

We discuss emphatically how to use data of current available to establish EMME/2 working platform.

The working platform of lens body for scanning can move with the accuracy of 10nm per step at three directions, which breaks through the restrictions on the thing that scanning range of piezoelectric ceramic, and it is not a device driven by piezoelectric ceramic but realizes the large range scanning.

The paper puts forward ideas to sort out,develop and apply aerial survey remote-sensing new technique within the system,set up unified aerial survey remote-sensing working platform,serve for state grid standardized construction,create a standard mode to serve power grid engineering design,construction and operation management in whole process.
