Accordingly, it showed that inorganic minerals and organic materials could affect the mobility and bioavailability of heavy metals.
Materials and Methods Soils.
Biochar produced under the high temperature had big specific surface area, mainly on account for oxygen element bagasse (raw material of biochar) contained.

If the spheres are of identical material, then γ12 = 0.
It is an equilibrium theory, it is only valid for short range surface forces and compliant materials (Tabor parameter greater than unity [7]), and provides no guidance on attractive forces prior to contact.
For nanoscale particles a key factor is their adhesive contact.
The JKR equation that emerged from the work has found use for the interpretation of adhesion results for a wide range of materials and nanotechnological setups.

Introduction Since client-oriented strategy becomes the key for enterprise to obtain the market competitive strength, the communication between enterprise and customer presents to be rapid, efficient and collaborative.
E.g. the building and machinery of enterprise, employees’ payment, raw material costs, promotion expenditures, etc., are separable costs which are afforded by enterprise, while costs of time and efforts of each participating party are inseparable costs whose quantification and distribution affect the contents and consensus of the treaty made by enterprise and customer.

Plasmodium material of drive parts is alloy,size is 35 mm×35 mm×35 mm, the purpose of adding two pieces of adiabatic body on and under the plasmodium is to prevent heat diffusion, in case of influence the control accuracy.
The key to this control around a reference value upper and lower switching,reference value with the input and system change adaptively adjusted, therefore less demanding on the mathematical model, suitable for time-varying system, and upper and lower switching amplitude deviation step by step by reduced gradually.
