However, the conventional applications in prior literature took these time-varying properties into consideration barely.
The calculation results showed that the time-varying properties influence the sloshing characteristics significantly.
Consequently, it is very meaningful to study how the time-varying properties influence the dynamic characteristics of liquid sloshing.
Influence of draining flow rate In a real spacecraft system, the draining flow rate is affected by many factors[17,18].
This means that the external excitations play more crucial roles in affecting the sloshing characteristics.

Oil film properties of three oil wedge sliding bearing and its effect to the rotor stability ZHANG Ai Pinga, LIN Sheng Qiangb Northeast Dianli University , China azap@mail.nedu.edu.cn, blsqiang007@126.com, Keywords: Three oil wedge,sliding bearing, rotor stability,oil film properties,CFD Abstract.
After learning three oil wedge oil film properties, it will be more meaningful to study three oil wedge bearing stability witch are effected on the other factors.
By calculating the navier-stokes equations to study oil film pressure characteristics witch can be effective to consider these factors that will be ignored by using Reynolds equation.
Oil is sticky fluid witch has rotating properties so that can't be neglected the eddy current and turbulence.
Only reasonable mesh can do guarantee the simulation result is close to the real oil film properties.

Friction may be affected by the following factors [3]: (1) surface texture; (2) normal loads; (3) sliding speed; (4) environmental conditions such as temperature and lubricants; and (5) material characteristics.

A negative coefficient indicates an inverse relationship between impact factor and friction coefficient.
Overall, the most significant factors were wire diameter and pore size.

Nonetheless, such materials have limitations regarding their mechanical, biodegradability, and other properties [9].
However, phosphate glass has weak mechanical properties.
Therefore, HA was added to enhance the scaffold’s mechanical properties.
Consequently, sintering temperature may have an effect on mechanical properties.
Future research could emphasize the improvement of related scaffold characteristics such as mechanical and biological properties.

The unbalance factors affected on the ultra-high speed grinding wheel and its system were analyzed, and its effects on the machining quality in the process were also discussed.
Because the centrifugal force is in relation to the angular velocity of the rotor ω, the balance grade is expressed as G e= ×ω (2) The centrifugal force is given by F = φω2 = mGω, therefore Gm /ϕ = ω (3) Unbalance Factors of Ultra-high Speed Grinding Wheel.
The factors related to the unbalance of the wheel system are as follows: (1) Asymmetry of wheel base material. (2) Dimension, shape and position error of the wheel due to machining process, assembling and fitting error of wheel system. (3) Wear and jam of wheel, fall and break of grits, etc.

So, it is important to study the vibration property of the wheel system in ultra-high speed grinding process [5].

Heating rate, temperature and time were the selected factors during experiment to be applied in the L9(34) Taguchi orthogonal array (OA) to find the best set of parameters to produce highest density of brown part.
Analysis of Variance (ANOVA) was employed to find the best signal to noise ratio (S/N) to express the contribution of the factors towards quality characteristic.

It was indicated that the cleaning power and time were the two main factors for damaging the insulating layer of the cleaning objects.
However, different cleaning objects and different application situations had different requirements for the properties of ultrasonic cleaning machine [5-6].
The cavitations of the ultrasonic cleaning could enter these cracks easily, and did rapid and serious damage to them. 1.3The major factors analysis for damaging the insulating layer of the cleaning objects By research, it was found that there were two main factors for damaging the insulating layer
Summary This paper analyzed the destructive effect mechanism of the ultrasonic cleaning, and indicated that the cleaning power and time are the two main factors for damaging the insulating layer of the cleaning objects.
It is demonstrated by the practical long time test of the motor that the ultrasonic cleaning parameters selected in this way will not destroy the insulating layer of the motor winding, and possessed safe and reliable properties.

Obtaining that the relative humidity and the days of curing influence the chemical and mechanical properties of the material.
One of the main reasons for the deterioration of the properties of composite materials is exposure to environmental factors.
The mechanical properties that were measured were the following: breaking stress, maximum and minimum stress, elastic modulus and deformation.
Average elastic energy over relative humidity vs days of curing Conclusions The comparison of the energy dissipated during the cohesive separation shows, first, that in the tests carried out the ideal time for the epoxy resin to acquire its chemical and mechanical properties is 7 days, since here the maximum value is presented, approximately 29 kJ.
