(Chinese automotive technique research center statistics data) Under the situation of ‘ship rises with the tide’, automotive industry after market are welcoming a gold period of profession development, As a young profession, the automotive maintenance are quickly developing by 10% to 15% each year.
According to different level after-sale service network, it have direct impact to timely product exchange and repairing, customer complaint reduction and product defect finding by selecting the suitable location to set level 1 and level 2 service network and deploy stock of spare parts in certain period and amount [4]. 3) The collaborative reverse operation procedure with product exchanging flow time orientation.
The time information of returning flow, exchanging process, the receiving and issuing quantity of spare parts, inbound-outbound logistics from level 1after-sale service network to national after-sale service center will be sent in data by information sharing system and on spot kanban mechanism.
If lack of the right data transmission for reverse forecast, the automatic replenishment system’s seasonal dynamic safety inventory couldn’t be set, hence influence the pulling of kanban.

The contact area between the upper and lower shear boxes remains unchanged during the relative movement periods, and the device is able to output the shear stress data changing with time by computer.
(4)Open the data acquisition system of the pressure sensor, click the start button, and start the power unit to begin shearing.
Collect the pressure data until it was basically unchanged, and then close the power unit
The clay mineral adsorbs water around after added with water, so that the cohesive force decreases with the increasing of the clay content and the enhancement of the particles lubricating effects, and the result is that the maximum shear stress and inter-laminar friction of the soil decrease; When the clay content is less than15%, the proportion of coarse particles of the soil increases and the friction angle increases, but the reduction of the clay content makes the adhesive force of the soil decrease more, so that the maximum shear stress of the soil and the inter-laminar friction of the soil decrease with the clay content decreasing.

Analysis of the test results and the questionnaire survey data found that the most comfortable rotation speed for human body was about 57.5 rpm.
Step 5: Analyze and calculate all the data.
Step 7: Use the data results of the first 20 minutes to analyze the relationship between the consumed calories and the kinetic energy imported into the refrigeration system.
In response to the environmental trend, recovery of the kinetic energy generated during exercise can contribute to energy saving and carbon reduction, while encouraging exercise.

With detailed data analysis, after leaching, the amount of pore ranges from 97μm to 320μm increased by 3.2% and the large pores with diameter larger than 582μm increased by 57% than before leaching.
The data of each subdomain was calculated, which then were composed of a 3D data set of 6×6×6.
The fractal dimension increased after bioleaching indicates that pore morphology evolved continuously and the micro-scale pores distributed more complexly and irregularly, since the corrosion of valuable components under the physical and chemical reactions, such as dissolution, adsorption, desorption, oxidation, reduction, etc.
