Introduction Lightweight is the inevitable trend of car energy conservation and emissions reduction, so it is a new topic that development and application high strength steel flexible roll forming automobile components with light weight, high strength and good safety performance in auto parts and machinery manufacturing field.
On abroad, Germany Darmstadt University and data M company, as well as Japan Takushoku University is the first study in this direction; In China, North China University of Technology in support of the National Natural Science Foundation of China has been successfully developed single and double axis flexible roll forming machine, and has a lot of researches and experiments.
According to relevant data of material tensile test, it should be defined as 0.099 which is maximum strain in the stage of material plastic deformation.

Results and Discussion Synthesis of Pb2Sr2CaCu3Sx The X-Ray powder diffraction data of the product (Fig.1 ) was almost the same as PbS ( galena ) reported in JCPDS Card No. 5-592 which has rock salt structure with the space group Fm3m and a= 5.936(2) Å [11].
This shows the reduction of Cu2+ to Cu 1+ .

Results and discussion In present paper the experimental data is presented on the catalytic activity of catalysts for the process of aromatization of n-paraffins from the zeolite deposit of Shankanay field, which is based on the selective recovery of transition metal ions at low temperatures under the influence of mechanical treatment.Taking into account, that the low temperature recovery is very selective resulting in the formation of surface low-coordinated ions, we can expect interesting catalytic properties in such systems.
Table 1 shows the experimental data on the influence of the degree of dispersion on the acidic properties of zeolite catalysts modified by nickel, copper and zinc.
Apparently, Zn2+ cations are localized mainly within the zeolite channels, forming acid-base pairs of the type Zn2+-O2- [56].Whereas, the preliminary grinding of the zeolite leads to reduction of the possibility of penetration of zinc cations into the zeolite channels, and therefore a smaller number of protons of strong acid OH groups are replaced by Zn2+.

The intput data rate is , and the baseband signal bandwidth can reach .
From the delay curve in fig.4, we can see that the minimum value of fractional delay can reach about 4ps at the 240MHz data rate.
The reduction of resource consumption is obvious.

All the data has been analyzed on the result below.
All the data is plotted on the Graph 4.41.
As a result, tremendous reduction on the flexure strain can be clearly seen.
