By measuring the recording data, we got the speed range corresponding to different water depth.
Data Collection Measuring Vehicle flow characteristics commonly uses traffic counters.
It is an effective method for obtaining large amounts of data.
Therefore, it was used camera data for obtaining vehicle and water status data simultaneously for parsing.
The data on car length was obtained from relevant data on car model length from the internet.

In the open literature, only a limited amount of data is available for this class of materials.
No comparative data is available for the Fe-22Mn-C-N TWIP steel.

This is confirmed by quantitative grain size data, which are represented in Table I.
All these data points are gathered for one specific IF steel which was submitted to a cold rolling reduction of 95%.
The data suggest that this grain refining has saturated beyond heating rates of 1000°C/s.
The grain size data obtained in this study are in reasonable agreement with data published by Muljono et al [3].
In Fig. 3 the textures derived from the OIM data are shown.

The significant progress is embodied in improvement for reduction or oxidation process and mild reaction conditions with fewer environmental pollution, and especially the high quality product (≥ 99.0%, HPLC) with favourable yield (beyond 64%) were obtained.
Although the route had many progresses for being free from awkward reagents such as LiAlH4 and BBr3, it still had some drawbacks, especially during scale-up trials: (i) In situ borane reduction needs low temperature, high molar ratio of reducing agent and difficult positive pressure operation had to be confornted with.
In reduction step, ester group of 3 was reduced directly by using NaBH4 combined with additives such as methanol or AlCl3 to replace the dangerous LiAlH4.
The data of 1H NMR was in correspondence with literature [15].

Combined with strength reduction method and using 3DEC for simulating Dazhai landslide.
Introduction According to the statistics data of Geological Environment Monitoring Institute in China, landslide which is related to rainstorm in our country accounted for about 70% of the total [1]. 13 large landslides in the 2010 of geological disasters are all related to rainfall.
According to the literature of remote sensing data and field measurement, the length of the water body which is full of rear fissure of landslide L1 is 25m, the length of the floating lift force works on the shear slide plane L2 is 360m, the average width of slide body L is 166m[7], the angle of rear fissure α is 75°.And the result of formula (1)(2) are as follows: hydrostatic pressure V=4.8×105KN, buoyancy U=7.2×106KN.
Use strength reduction method to reduce parameters.
When the reduction factor K increases to 1.19, the model reaches instability.

So, a vehicle sound data sample was used in examining our new data producing method.
Next, the small probability sample data was picked out to form a new data set(also called Grey Hazy Set) and the left data to form another data set(called large probability sample).
(13) With accumulation-reduction processing of X(1) , the prediction equation of X(0) is got: (14) in which k=0,1,… ,and .
Inserting data of small probability data sample.
Conclusion This paper deals a problem of how to increase the data amount of inadequate data sample with unusual data.

On the contrary, trapezoidal numerical integrals were exploited to process the fluctuated-data, which were in good agreement with the predictions.

Since it was inconvenient to process the 40s data if it was separated to 10 parts, and it was not certain that the exact amplitude could be extracted for each part successfully.

The maximum punch load increases with drawing ratio, and maximum 5.5% of load reduction was measured when DR=1.74.
The research papers reveal that the reduction of forming load can be attributed to the various mechanisms; stress superposition, acoustic energy absorption in local regions(vacancies, dislocations and grain boundaries), reduction of interfacial friction, and thermal effect.[8] However, the load reduction in sheet forming might be only surface effect by the reduction of interfacial friction because ultrasonic energy is not enough to cause acoustic softening in the material.
Mechanical properties were obtained from uniaxial tensile tests of the SPCC and the results were characterized to use as input data for finite element simulations.
The relationships between anisotropy parameters and Lankford coefficients are as follows, ; ; ; (3) Mechanical properties and the parameters to describe hardening and anisotropic behavior are listed in Table 1, and those were used as input data in finite element simulations.
By comparing the experimental results when LDR=1.74, 5.5% reduction of forming load is attributed to 16.7% reduction of interfacial friction by ultrasonic vibration.

The pseudo-first-order kinetic model for 2,4¢-DDT and 4,4¢-DDT reduction with zero-valent iron was proposed.
The data from the variable-pH experiments (between 3.6 and 8.8) suggested that pH does not play a role in the rate-determination step.
Oxidation-reduction potential was measured with a redox combination electrode (Pt/ Ag/ AgCl) placed into the test reactor.
Results and discussions Reduction of DDT by zero-valent iron After sealed the reaction vial, the oxidation-reduction potential of solution measured with a redox combination electrode first rapidly decrease, and continued slowly decrease to –350mV.
Reduction of 4,4¢-DDT was generally faster than 2,4¢-DDT.
