Experiment
Preparation of active floridin Taking ca-bentonite as the raw material, it was dried at 100℃ for 2h and then smashed into particles with diameter of 74um.
Then the material was centrifugalized, dried and smashed.
BET nitrogen-absorption was used to measure the specific surface areas of the active floridin prepared by using the raw material bentonite, H2SO4, mixed acid, and the corresponding specific surface areas are respectively.

Introduction
Brass and its alloys are the materials which are widely used in friction parts of machines, as bearing liners, bushing, etc… Properties such as high strength and ductility, fatigue strength, wear resistance, etc [1].
Are necessary for these materials, and it is important to understand microstructure change at the work interface.
For ductile materials, such as brass, plastic deformation plays an important role in different atmospheres.On the other hand, before the wear particle is produced from the rubbing interface, it grows as the transfer particles.
The materials studied were a CuZn brass alloy and steel AISI 1045 with the following chemical composition in weight percent, respectively: for the pin 64% Cu, 0.25% Si, 0.11% Al, 0.21% Fe and the balance Zn; for steel disc Fe + 0.45% to 0.51% C, 0.5% Mn, Si < 0.1, P < 0.035% .

Our results indicate that the anisotropy in these materials is mostly due to the tensile strain in the GaP layers.
Introduction The progress in novel growth techniques, has made it possible to grow high quality semiconductor heterostructures and superlattices (SLs) from heavily lattice mismatched materials [1], up to a lattice mismatch of about 7% if the layers are kept sufficiently thin.
The semiconducting strained SLs are potential materials for various electronic and optoelectronic devices [2,3].

Preamble
With the fast growth of the global economy, cement, as one of the chief building materials, maintains a steady growth trend in terms of the demand; the cement industry, affected by the change of the world economic pattern and restrained by the raw materials for production and the environment protection, is confronted with the upgrading of the industrial structure and the adjustment of the production bases, so it calls for the sustained increase of its scale of investment.
