4.The existing problem with anti-sway device of RTG is improved in this paper, so that the easy damage of coil of electromagnetic valve, the easy wear and tear of anti-sway wire rope and the inner leakage of cylinder are solved and the expecting purpose to improve them is attained.
6.This new measuring method with three dimension coordinate measuring and data processing can be utilized not only for measuring cylinder bore surface but also for parts with cylindrical surface such as the inner and outer cylindrical surface of cylinder sleeve and crankshaft journals.
7.Promeristem is composed ofthree layers of cells in root tip,of them,outer layer of cells form the epidermis and root cap,centraland inner layers of cells sepratedly form the cortex and vascular cylinder.
8.The high seam drill 2000 is stainless steel construction and the cylinder rods of the 1st inner legs of the stinger and drill leg are stainless steel.
9.If it is possible, the rooms for GC, ICP, ICP-MS should have a buffer area for gas cylinder cabinet and noisy compressor storage; thereby the buffer room will keep the inner area of the room clean.
10.The digital cylinder put forward in this paper adept closed loop control system, effectively compensates to the changes of the velocity and displacement, reasoned by the system temperature, the load, the inner leak, the dead band, and bring more precision.
