Due to the complex curves of hull frames and the un-uniform mechanical properties of material, it is hard to realize the numerical control of frame shape processing.
Comparing with other control methods, it is easier to use; and the feeding error affects less on the accuracy; the shape of the whole frame and every part of it is more accurate.
Due to the un-uniform mechanical properties of material, it is not fitting to solve this problem with theoretical calculations.
The excess part called as excess-angle will affect the application of gradually approaching method.
It is determined by many factors such as the length of the period, response time of the electrocircuit and solenoid valves, the curvature of the frame shape, temperature and so on.

It can eliminate the jitter of target image due to the tracking error of telescope drive system, the mechanical vibration of telescope itself and atmospheric disturbance by its own rapid swing[2].The dynamic characteristic and surface of tip/tilt mirror directly affect the effectiveness of the tracking compensation[3,4,5].
To satisfy the performance requirements of mirror mechanics on this working condition and the surface accuracy under this mechanical properties, tip/tilt mirror must have higher first order natural vibration frequency.

Change in lubrication can alter the mode of deformation during forming processes and change the mechanical properties of the final product [1].
The polishing process will be repeated for each test to ensure that the result will not be affected by other factors.
The observation plane was not affected by the frictional constraint of the parallel side walls.

Crack phenomenon and causes Many factors will cause cracks of aerated concrete block walls, such as material properties, construction seasons, construction quality, the service conditions, temperature changes, the engineering geology conditions and so on[1-2].
But there are some special properties in the wall with aerated concrete blocks.
But horizontal crack at the junction of walls and beams or floors is more common still because it occur considering two factors, dead load of material and shrinkage of mortar stitch.
The different properties of aerated concrete block and plastering mortar lead to different expansion and shrinkage between aerated concrete block and plastering mortar, which caused cracks of aerated concrete block walls, as shown in figure 6.
Bonding agent is jetted uniformly on the walls by using mechanical pressure.

Two types of internal interfaces with fundamentally different properties exist in the nanomaterial: the grain boundaries between the nanocrystallites and the interfaces between the agglomerates.
On the other hand, the so called triple product P=sδDgb was determined in the regime В-В (s is the segregation factor).
The method of calculation of the segregation factor s for Ag in FeNi is illustrated (c).
As a result, the temperature dependence of the segregation factor s can be derived (Fig. 3c).
In spite of the fact that the hypothesis of non-equilibrium GBs is quite plausible and capable to rationalize many unusual mechanical and functional properties of ultrafine grained materials obtained by severe plastic deformation, its unequivocal experimental proof is still lacking.

A criterion for mechanical stability of the parent phase is: ( ) 02 0 2 2 >=      ∂ ∂ = A f ηη η , (3) The curve (a) in Fig.1 show schematically Eq.(1).
When both austenite and martensite are mechanical stable, Eq.(7a) and (7b) can be united into 0>a .
In more traditional alloy systems, such as iron-base alloys, the coefficient a shows normal weak negative temperature dependence; but in numerous systems, such as nonferrous alloys, oxides and other compounds etc. the coefficient a exhibits anomalous positive temperature dependence, which is usually observed in connection with the thermoelastic martensitic properties [18].
We select 50=κ in our calculation since the choice of κ does not affect the following discussion.
The chemical driving force of martensitic transformation and elastic constants of material are predominant factors to affect interfacial structure.
