Using fluid
dynamical lubrication theory, theory analyses and mathematics modeling on lubricate induce force
in plane grinding with non-porous grinding wheel were carried out, also the computer simulations
were done, and the conclusion was theoretically verified by tests in interrelated material documents.
According to some material documents, the layer equation can be used when Reynold number is less than 300, between 300 and 3326 the confused flow model can be selected, Ng and Pan models can be used while more than 3326.
To verify correctness of computer simulation results, in the section according to same parameters conditions the computed two-dimension hydrodynamic experimental distributing curve in grinding area afforded in material documents, the displaying results were accordant with the reference document [1], from one point of view it explained the veracity of this software's simulation results, and could be used to theoretically analyzing grinding process.
Conclusion By some simulation researches with variable conditions, influencing factors of lubricate induce force in super high speed grinding area was discussed, the conclusion was basically coincident with results of interrelated material documents, and it might be a assistant way to research on super high speed grinding.

The major building materials of the house system are reproducible (like straw and xanthan gum) and recycled raw materials (like alloy and ceramics).
Raw materials lay the foundation of "zero carbon house".
The roof adopts the building materials which integrate heat preservation, heat insulation, and waterproofing.
Thirdly, the green materials of ecological house can insulate and preserve heat, so it can reduce the use of air conditions.

The vibration characteristics depend on a number of factors such as material properties and
dimensions of a plate, crack lengths, positions and directions of a crack, and boundary conditions.
The numerical computations were executed on one-quarter of the plate Journal Title and Volume Number (to be inserted by the publisher) 3 with an aspect ratio L/W=2, using four combinations of symmetry and anti-symmetry conditions along the x- and y- axes.
