If the die roll height of power transfer part like gear is large, then a structural defect can occur due to the reduction of power transfer surface.
The die roll heights of three fine blanked gear samples were measured in optical measurement inspection system(Datastar 200) and Table 3 shows the measured data of die roll heights on the gear samples.

According to the following steps back analysis:
First, residual pore pressure ratio of different weakening soil and effective strength parameters of different relative density soil were Generation into the formula (2), (3),then the actual soil strength Φ of different relative density and different weakening state soil;
(2)
Where:-residual pore pressure reduction coefficient
-pore pressure ratio
(3)
Where:-effective strength,°
Second, a k was supposed, according to pile and soil parameter the p-y curve in reference [2] of different relative density and different weakening state soil was determined, and winkle foundation beam model was established.
Considering the pile diameter of 0.02 m model test data was more less, 3 d finite element analysis results in reference [2] were cited.
According to data in table 2, figure 7 gives the corresponding relationship of the foundation force modulus coefficient and degraded soil strength, and these data were fitted, the equation (4), (5) of foundation force modulus coefficient and degraded soil strength corresponding to pile diameter of 0.042 m, 0.02 m were obtained.

A little change in the backward reduction in cross- sectional area of different types of extrusion process.
The flow curve of lead alloy was determined by torsion tests and data was used in numerical analysis.
The data that was obtained from FEA model included extrusion force, effective stress and strain and material deformation flow [6].
The experimental data was compared with simulation results for multi hole extrusion process.

It is well known that high thermal gradient will be favorable for a reduction of porosity content in aluminum alloys castings, but the effect with solidification time is not discussed yet.
All the thermocouples were connected to a data acquisition unit to record the variation of temperature with time.
And all the data points for 1cm and 2 cm thick plate castings in figure 4 is split into two bands.
All the data points (1cm and 2 cm plate castings) are mixed and not the same as Fig.4 split into two bands clearly.

The driver of energy-saving car usually be very thin and small so as to light the weight of the whole car and reduce energy consumption.So this paper choose size data of the 5th percentile humans which could be got from China national standard GB10000-1988”China adult body size” [4](N.B. the size data are got from the male between 18 and 60 years old; female between 18 and 55 years old.).Besides,with some adjustments, this method(use uncomfortable indexes to measure comfortable feeling) also could be used into the production car.
But the minimum ground clearance’s reduction results a little increase of drag coefficient(Table 4).

Identification of the powder X-ray was carried out based on the filing of the International Centre for Diffraction Data (JCPDS-ICDD).
When the agglomerates reach this 0.6 ... 1 mm, as indicated by the data of electron microscopy images (Fig. 1a, 1b).
According to AFM data for all modes of electroconsolidation chipped in compact passes along the grain boundaries (agglomerates) with the presence of characteristic between grain and between subgrain facets with "streamlet" pattern that apparently indicates instability boundaries [3].
Most samples are characterized by heterogeneous structure, and supplements metastable Al2O3 nanopowders cause the shift of the shrinkage of the tetragonal YSZ to high temperatures affect the reduction of the grain size of the tetragonal YSZ to 170-200nm

Toxicity of carriers was determined by the MTT reduction assay [10].
The data were reported as the fraction of the viability of the cells treated with the carriers for 24 and 48 hours relative to the viability of control cells unexposed to the carriers.
The data are reported as the fraction of the viability of the cells incubated with (A) tween 80, (B) Mβ-CD and (C) liposome for 24 (solid bars) and 48 hours (open bars) relative to the viability of control cells unexposed to the carriers.
The data was reported as the amount of complexes delivered per 10 6 cells.
