General With the development of science and technology, the measurement will be changed from micro to nano in the manufacturing field.
At present, in some industrial field, requirements have been put forward for nano scale micro-positioning table, such as semiconductor devices, optics, manufacturing of miniature and special materials processing, etc.
The precision ceramic type linear motor is selected to drive this system based on the comparison of performance, and the precision piezoelectric ceramic motor is adopted as the driving components, which has the characteristic of small size, low cost, high power output, fast response and high precision and no electromagnetic interference, its driving principle is adopted the piezoelectric materials.
Since the granite material has many advantages of the high stiffness, high damping coefficient and low thermal expansion coefficient, the material for the motion platform can improve anti-vibration and thermal stability of the whole platform.

Introduction An instrumented indentation technique, developed to characterize the mechanical properties of small-volume materials [1-4], is adopted as a nondestructive stress-measurement method.
While the curve shift in the Journal Title and Volume Number (to be inserted by the publisher) pure-shear state is negligible, the amount of the stress-induced load shift is linearly proportional to the applied average stress because the averaged effects of the surface biaxial stress are transmitted along a unique indenter column.

Compression Test based on Piston Material 175-piston material is aluminum-silicon alloy, with the piston diameter as 75mm and height as 70mm.
This compression test is performed by microprocessor control universal material testing machine on the basis of the 175-piston.
According to the aforementioned experimental result we can arrive at the conclusion that the corresponding strains of the piston aluminum-alloy material are respectively 0.00091 and 0.0029 when the stresses reach 62Mpa and 180Mpa.

Preface A single CFST column can combine steel tube and concrete effectively, and develop the two material properties fully, thus gain the extensive favor in engineering, but when the load is eccentric or the slenderness ratio of component is big, a single CFST column is hard to develop its optimal property.
The Combined Material Poisson’s Ratio of Column Steel Tubes. the relationship curves of column tubular sectional load-combined material Poisson’s ratio of specimen is shown in Fig.9.
In later stressed phase, the combined material Poisson’s ratio begins linear ascend until failure.

A subclass of these materials is referred to as intermediate valence fluctuating or inter configuration fluctuating compounds and sometimes as mixed valence or mixed configuration compounds [1-7].
They form a very interesting group of materials in which many characteristic phenomena related to their electronic properties are observed.
