Fig. 7 Test value and fitting equation value of creep coefficient of test beams As we known from above, loading time, environment conditions and prestress level are main effective factors to bend creep strain of prestressed concrete beams.
Also as we known from literature [3-10], many factors maybe effect creep behavior of prestressed concrete beams such as component section size, concrete age as loading, the strength of concrete and reinforcement ratio.etc.
Because the factors who have effect on creep behavior are variety, complexity and random, based on test results and combined prophase research achievements, creep coefficient expression considering some factors is as following: (3) Where, φc (t, t0) is creep coefficient value from time t0 (days) to t (days), φc (∞, 28) is bend strain creep coefficient end value at approximate standard conditions from 28th days, whose temperature is 20±3oC and relative humidity 80%, and for prestressed concrete beams with pretensioned bent-up tendons, φc (∞, 28) maybe valued 2.25. k0 is a influenced factor resulting from stress factor such as prestress degree etc. and based test results and results by midas-civil software, to prestressed concrete beams with pretensioned bent-up tendons, k0=1.25/λ, here, λ is prestress degree.

The polycondensation experiments were conducted in a 1-liter stainless autoclave fitted with a mechanical stirrer, thermocouple, gas inlet and outlet valves, pressure gauge and cooling coil.
Kinetics of polymerization reaction can be achieved by both indirect methods [8-11] in which a physical property relevant to the extent of reaction is detected and direct methods [12-16] in which the concentration of reactant or product is determined.
Similarly, the exponential factors (a and b) represent the order of reaction with respect to DHPS and DCPS, respectively. k is the rate constant and can be described by (3) Where, A is pre-exponential factor, Ea is activation energy, R is the universal gas constant, and T is the temperature in Kelvin.
Thus solubility of DHPS salt in NMP is one of the key factors affecting reaction rate even the final polymerization degree.
In PPSE preparation, it was found that concentration of catalyst 2A (defined as Catalyst2A/DHPS molar ratio, nc2A/nDHPS) could be another factor affecting polymerization.

In addition, the flux pinning exhibits a variety of special characteristics, such as no-mechanical connection, the passive stability and the selective constrained degrees of freedom (DOFs).
As is known with experiment, the mutual force is relative to lots of factors, such as the magnetic strength, the gap between the HTSC and PM and field-cooling height, as well as the temperature of HTSC.
It is known that the flux pinned vertical force dependent on other factors, such as the property of superconductor material and the influence of temperature, so a new proportional coefficent of performance is added into IDM.
The improved formula is given vent with addition of a novel proportional coefficient of performance affected by other factors.

These include its unique guiding and dispersive properties, a wide range of single mode operation, highly birefringent characteristics (~10-3), and high-power light transmission, etc.
Birefringence caused by geometrical factors, such as elliptic holes or nonsymmetrical cell arrangement in PCF, has been reported by Lin [5].
The stress distribution will greatly affect the birefringence of PCF via general photo-elastic relation.
In this report, we present some of the design factors on the influence of PCF birefringence.

In this paper, the damage forms of high-speed railway wheels in China are introduced, and the main influencing factors of wheel failure are discussed in combination with wheel damage characteristics.
But research into high speed railway wheel damage still focuses on single wheel failure analysis, and a systematic study in application failure, influencing factors and failure mechanisms of high speed railway wheels is lacking [9-12].
Influencing factors and various types of injuries are also investigated by failure analysis methods.
Research shows that there is a significant difference between the elastic properties of brittle inclusions and the matrix [17,18].
But once there are foreign metal particles, especially with the greater hardness remaining on the rail, both wheel and rail damage will be caused, thereby affecting the running of trains, increasing maintenance workload and the cost of wheels and rail in high-speed railways.
