Introduction Alumina ceramics are widely used in machinery, electron, national defiance and other industries because they have high smelting point, great hardness and excellent mechanical wear- resisting property.
In order to obtain high density ceramic material, this research used homemade sub-micron aluminum powder as raw material, investigating the influence of sintering temperature and molding pressure on the properties of high density ceramic material.
During the process of sintering of ceramics, sintering temperature is a significant factor which affects sintering process and microstructure of sintered bodies.
Thus the property of materials will be the excellent.
When the sintering temperature is 1550 °C, the properties of samples are best, in which volume density is 3.71g/cm3.

In this simulation, HYSYS software was used for calculation, and PR and LKP physical properties packages and COMThermo database were selected.
HYSYS provides a powerful set of physical properties computing packages, and its basic data is also from the world's renowned physical data system, which has been rigorously verified by the company.
For components not included in the HYSYS standard library, the underlying data can be automatically calculated by defining a spurious component and then selecting HYSYS's physical properties calculation package.
These factors often have contradictory trends and require a comprehensive consideration of the adoption of a compromise.

This paper discusses how the orifice layouts and the orifice diameter affect the self-excited vibration of the aerostatic guideway, or two-dimension x-y stage as a whole.
Because of its high accuracy and low friction properties, it has broad applications in the field of large-scale integration (LSI) manufacturing, micro mechanical processing, anatomy of fine structure of organism, two-dimensional precision measuring and so on.
Fig. 1 Structure of aerostatic x-y stage Fig. 2 Factors of causing the self-excited vibration Many factors can cause the self-excited vibration of aerostatic stage, such as supply pressure, diameter of orifice, diameter and depth of air pocket, thickness of gas film[7], etc, among which diameter of orifice and the structure of orifice (with or without air-pocket) are the main factors, as shown in Figure 2.
