The defects of the process were as follows: firstly，a high reaction temperature; secondly, a large number of wasted zinc powder; thirdly , dear and severe environmental pollution.
The Zn, Ni metallic grains were well-distributed on the surface of P-mSA membrane.

Technical specifications for construction of highway roadbases（JTG 034-2000）stipulates that: When using the cement stabilized soil as base in the pavement structure, for granular soil and coarse grained soil at the time of mixture composition design cement dosage should be 3~7%.
The number of each parallel mixture specimens was 6.

Improper soaking time and cooling time will make pull crack and big grain of casting [3,4].
Due to the large size table, the casting equipments, machining equipments, hoisting equipments and workshops used to make its also require large-scale corresponding, a number of large equipment and the plant will cause the high cost of production.

The author of this paper analyzed a large number of documents and data about active coke desulfurization, and discussed the reasons why does this technology not be used widely on the basis of the economic analysis.
Fig. 1 Samples of active coke In present, active coke is mainly used in removing of SO2 in flue gas using the moving bed, the range of iodine value of generic active coke is 400~500 mg/g, so this technology has a certain requirements to its sulfur capacity, strength and abrasion resistance, grain size, anti-drug resistance and anti-poisoning properties, as well as the adsorption process and the desorption rate.

Most of such techniques lead to formation of highly developed dislocation/grain microstructures and cause compressive residual stresses, providing significant hardening in the material's surface layer and increasing resistance to fatigue, wear or corrosion[1].
A major problem for this field of research is the tremendous commercial interest in applying this technology as seen by the large number of patents produced by General Electric for turbine blade applications.

Its value is to provide readers how much knowledge content, and not to provide service time or the number of offer.

After the Three Gorges reservoir, Yichang hydrological station small runoff, the low flow rate increases year by year, sediment discharge and sediment concentration greatly reduced, suspended sediment median diameter taper, a large number of coarse grain sediment was blocked in the library district, reservoir discharge’s "clear water sand" is considered unsaturated sediment, therefore sandy pebble reach overall performance consistency erosion.

Introduction A lot of limestone powder has been produced during the production of concrete aggregate, which not only takes up a large number of arable lands, but also results in dust pollution and waste of resource when accumulated for a long time.
The mechanism of limestone powder in concrete mainly is micro-aggregate filling effect, micro-crystal nucleus effect and activity effect, whose activity effect is very low [12], basically ignored during 672 h; fine particles of limestone powder on the one hand fill in cement particles to improve grain composition of cementitious materials and increase the uniformity of particles and proportion of fine particles, on the other hand fill in the concrete pore to bring about interfacial structure and cement paste more compactly, improve concrete internal structure, stop cementitious materials from hydrating further, which reduce autogenous shrinkage of concrete playing micro-aggregate effect at the same time and the decreasing effect is more evident with the increase of fineness; limestone powder reduces nucleus formation potential barrier because of serving as the nucleus formation matrix of hydrated calcium silicate and plays micro-crystal nucleus effect to bring about accelerating the hydration
