It makes the land stalinized year after year and output of the grain.
It shows in Fig. 3: Fig. 3 Influence of UASB reactor operation days on turbidity removal From Fig. 3: the wastewater turbidity removal is rising with the increase of the number of days running device.

The 13~15wt%TiO2 in ceramic coating helps reduce the porosity of the coating and increase compactness, malleability, and binding strength between grains, thus to avoid easy brittle peeling during wear process of the coating.

Force was applied to a SE(B) specimen until unstable brittle fracture occurred in the transition temperature region in order to obtain the value of cJ , which was then converted to CJK ( :, EEJK cJC ⋅= elastic modulus).When the number of valid CJK data measured at the same test temperature is more than six, the reference temperature ( oT ) was determined.
QLT treatment lowers the ductile brittle transition essentially by refining the grain size of the alloy through precipitation of thermally stable austenite in a dense distribution along the boundaries of prior martenite laths, hence destroying the crystallographic alignment of martensite packets and preventing cooperative cleavage[5] .

It is known that some complex media such as sands and rocks exhibit strong nonlinear acoustic phenomena, due to the weak bonding between micro-grains [1].
While a number of investigations have been reported on the nonlinear stress-strain behavior of C/C composites due to micro-damage developments, e.g. [5], the present findings show that this material also exhibits significant nonlinearity in dynamic processes such as ultrasonic wave propagation.

Introduction Solid rocket motor (SRM) survivability depends upon the structural integrity of the grain and all bonded interfaces.
At present, large numbers of experimental study on adhesive system has been carried out [1-2].

A number of different metals and metal oxide nanoparticles have so far been encapsulated into the shell of conducting polymers, giving rise to a host of composites [5–6].
As the CeO2 concentration increases, the compactness of the sample increases causing coupling through the grain boundaries to become stronger which could enhance the conductivity.

We screened a number of plant pigments and Gardenia jasminoides has been chosen as the object of study.
The grain size distribution of nano-TiO2 nano particles is uniform.

Originally spouted bed was just suitable to grain drying, and the area of its research and application are steadily extended.
Conventional spouted bed consists of two parts: 1) Cylindrical main body, certain number of fluidized particles with diameter larger than 1mm is loaded in advance; 2) Conical base body, entrance of airflow is in the bottom of it.

However, due to the open grain characteristic of porous asphalt mixture, the utilization technology of RAP on recycled porous asphalt mixture has the following features.
