The oil pump operation noise is mainly classified into fluid noise and mechanical noise.
Therefore, the rotational speed of centrifugal pump is the main factor which influences the internal flow noise of the pump[6-7].
With the cyclical rotation of inner and outer rotor, the pressure of trapped oil in the inlet chamber will change rapidly, so the occurrence of cavitation phenomenon probability will also increase. 2.2.3 Noise control methods based on simulation results It can be known from the simulation result that flow fluctuation, oil-trap phenomenon and cavitation are the factors which cause noise.

Modern requirements suggest an increase in all listed properties, at the same time the design should be technological in the manufacture and use – with a small weight and overall dimensions [2].
In order to increase the physical and mechanical propert of the coating, It was decided the sputtering of the target in a nitrogen atmosphere.
Further increase in the thickness of the coating does not significantly affect the attenuation of the thermal neutron flux.

Then, the equation 5 and 7 are solved according to the fatigue material properties to determine the fatigue life.

Variability range of Sm and Sa depends on many factors of random origin closely related to the mode of a machine operation.
Calculation of fatigue life is largely affected by the results of experimental tests in the field of cyclic properties description, according to the stress based approach [1, 2, 7, 10], strain based approach [8] or energy based approach [6].
The parameter of plastic strain energy DWpl is determined on the basis of an analysis of stress-strain loop from the period of life characterized by stability of cyclic properties.
Cyclic properties of C45 steel were determined for specimens with geometrical characteristics defined on the basis of PN-84/H-04334 norm.

Introduction Starch is the main composition of corn that significantly affects the processing qualities of corn that mostly lie on the physiochemical properties and textures of starch pastes and gels.
Changes of these properties directly influence the qualities of corn food.
Murthy et al [4] used two saccharification and fermentation processes to improve the fermentation characteristics of endosperm fraction from dry degerm defiber process and concluded the wet process had the highest fermentation rate.This work aimed to examine the effects on functional and structural properties of corn flours by three different processing and find the rules of starch and protein changes so as to realize the better use of corn flour to foodstuff.
Centrifugate needed to concentrate before examining thermodynamic properties by DSC.
Extrusion of starch granules causes changes in their morphological and molecular structure depending on several factors including moisture content, cooking temperature, and mechanical/thermal energy input.

The problem of thermodynamic model of electrode material removal under single spark discharge is described as below: 2 2 2 2 1 T T T a t r z ∂ ∂ ∂ = + ∂ ∂ ∂ (2) Where, α is the coefficient of thermal diffusion of electrode material, T is the temperature difference between thermal affect region and base material, t is discharge time, r is radius of thermal affect region, and z is the depth of thermal affect region.
So in short pulse duration, electrostatic force is one of key factors to remove the material.
In order to simplify the calculation the following assumptions are given: (1) The temperature distribution of the discharging channel is steady and heat flow density is constant. (2) Except for the yield strength, the properties of the material do not change with it's temperature. (3) As the discharge time is very short, the electrode is semi-infinite. (4) In the spark channel, there is no variation in potential ion; electron densities and ion velocity in the radial direction.

Its efficiency affects the whole efficiency.
When designing vacuum gas circuit, first to ensure the sealing properties of the gas circuit.
Another factor should consider is the seal rings must be replaceable.
Therefore, replaceable seal ring is a key factor to consider.

The concept of architectural decoration In recent years, with the development of social economy and construction industry, building design technology has also experience a process of improvement, the use of digital technology ,as an especially feature, has become an indispensable factor in modern architectural design.
With the development of economic globalization and the arrival of the digital age,computer technology and the imformation network into the main characters of the digital technology to people’s production and life has a great influence,the building design is no exception.[2]Before the invention of computer technology,the traditional architectural decoration design was achieved mostly by hand, which greatly affect the efficiency of the design.
Autocad has extensive adaptability, it can be run on various operating system for microcomputer and workstation and wildly used in civil construction, decoration, electronic circuits, mechanical design, costume design, aerospace, light industry, chemical and many other fields.
