Produce spindle shaft rotational error of the main reasons: The spindle the few paragraphs journal Coaxial error, Bearing itself various errors, Concentricity error between the bearings, Spindle around degrees.
The correct selection of tool materials and the selection of a new type of wear-resistant tool materials, a reasonable selection of tool geometry parameters and cutting parameters, coolant, can minimize the size of the tool wear.
Machine, tool and the workpiece is subject to a variety of heat sources, the temperature will gradually rise, meanwhile, they are also distributed to the surrounding material and space heat.
Can also be used insulation material will be separated from the heating member and the machine bulky.

The basic concept is that central region of the reactor core is filled with fertile (blanket) material.
During the reactor operation fissile material accumulates in this central region to compensate fissile material loss in the peripheral core region and also contributes to negative coolant loss reactivity effect.
And the core of SPINNOR surrounded by a reflector material.
Table 2 General Characteristics of SPINNORs 1) Parameter Value Power level 6-100 MWe (17.5-275 MWth) Operating time (without refueling of shuffling) 10 – 35 years Fuel material Nitride, MOX and Metallic fuel Fuel Volume Fraction 50-60% Coolant volume fraction 30-35% Cladding material Stainless Reactivity Swing Less than 1 $ Calculation Method The calculation method used in this study is as follows.

This paper adopts two intelligent materials, magnetorheological fluids (MRF) and magnetorheological elastomers (MRE).
MRE is made by the high polymer (such as rubber, etc) and magnetic particles, with the advantages of magnetorheological materials and elastomers.

Reinforce by Pasting CFRP means that paste Fiber reinforced composites to the tensile zone of reinforced components with cementing materials and make it work together with reinforced section, Then enhance the bearing capacity of component. it have the advantages of corrosion resistant, moisture proof, hardly increasing self weight of structure, durable, lower maintenance cost[1-4].
And the concrete failure criterion used William-Warnke 5 parameters failure criterion, outsourcing CFRP materials elements used by SHELL41 membrane elements, this elements can sustain Axial-Force only, and no resist tension and compression capability, accord with stress condition of CFRP in concrete.
Stress-strain relationship of CFRP material used ideal elastic models.
