positioning time การใช้

• Lift position time interval
• Minimum positioning time
• But the disadvantages are heavy communication cost and corresponding influence on enegy cost , network communication load and positioning time
• The study result shows that the complete dynamic response process of structure varying with loads is showed with time history method , and the position time and damaging style are showed when the cracks appear
• In the lamost ( large area multi - object fiber spectroscope telescope ) project , 4000 optical fibers are mounted on its focal plane which diameter is 1 . 75m . the positioning precision less than 40 microns , and positioning time less than 30 minutes
