This change can be analysis by the torque of wring, the data test under wind-force of 5 grades is shown in Fig.3.
Such result needs more time -load data to satisfy process of data transformation for obtaining the dynamic performance of wring.
For accurately analysing the working load of hydraulic system in typical working conditions, the root mean square value is to transform the data from testing and integrates the mean value and standard deviation.
Choosing a set of load data from Table.1, the strength test is imposed to reel and the result shown in Table 2.
The critical load of reel is computed by data in Table.2 due to Eq.3, its value is 520.52 kN, which shows that the component will not damage after one million repeatedly load test.

The temperature 1150°C was chosen on the basis of preliminary reduction experiments in the muffle furnace and according to the data of the thermodynamic analysis [11-12].
However, the iron reduction was incomplete.
For complete reduction of iron, it is needed to increase either temperature or time of reduction.
Thereby, only increase in reduction time is possible to perform the complete iron reduction.
Phase composition of ore after reduction (Fig. 2).

This would correspond to the complete reduction of WO3 to WO2 (f = 8.35), indicating that at relatively low temperatures reduction of WO2 to W start before WO3 is reduced before the reduction of WO2 to W takes place.
According to thermodynamic data [32, 33], decomposition of methane into carbon and hydrogen is possible above 823 K.

Damage assessment of high-rise hybrid buildings structures based on monitoring data
Monitoring data is the basis of this method.
The monitoring data here refer to are the real-time monitoring data in the process of earthquake.
In this paper, there are two sources of real-time monitoring data: first, the real-time monitoring data that be got when the structure meet the real earthquake; second, the monitoring data that be got from shaking table test.
Utilize monitoring data to amend the result of finite element.
However, using the incremental loading method, a series of monitoring data will be got if the monitoring data is from shaking table test.

With the anti-shear parameters reduction, the nonlinear strength reduction FEM model of slope turns to unstable status and the numerical non-convergence occurs simultaneously.
Efficient and accurate, the strength reduction FEM is feasible to examine slope stability and analyze slope movement patterns.
This can be determined either by statistical method, which analyses the correlation between the observed loads and deformation data, or deterministic method, which utilizes information on the loads, properties of the material, and physical laws governing the stress-strain relationship.
At that point, the limit reduction factor obtained based on c-φ reduction algorithm can be regarded as equal to stability factor obtained using limit equilibrium method[8], the method can be expressed as Eq. 2, in which the F is the reduction factor, also is equivalent to the safety factor.
