A large number of rural surpluses inflexed into township enterprises.
Since 2004, within the range allowed by the WTO agricultural rules, our country gave direct subsidies to grains; gradually canceled of agricultural tax; cancel the special agricultural product tax, animal husbandry tax and livestock slaughter tax, gave farmers subsidies.

Because there is some disadvantages of using Marine animals carapace to extract chitosan, such as the sources of the raw materials are regional restrictions, aquatic animals’ seasonal breeding lead to the raw material supply fluctuate, handling the calcium carbonate in animals shell needs a large number of acid and it will produce a lot of wastewater [5].

When samples are calcined at higher temperatures, the adsorbed water and hydroxyl number of them decrease, and a lot of rutile phase appear, and then cause poor photocatalytic performance.
The results indicate that (Fe, N) doped together also has the effect of refining the grain size and the samples have larger specific surface areas and better photocatalytic activity.

Introduction Zn-Al-Cu type alloys are characterized by a number of advantageous properties which include: good castability, good tribological properties, low energy for shaping of the products.
The main alloying addition is aluminium [3], its addition increases the castability, influences the size reduction of grains and improves the mechanical properties [5].

The section of the existing wall panel But designs of fast-mounted buildings have a number of essential shortcomings: Big body weight of a design; Conservatism (doesn't reflect tendencies of development of materials and designs); The low heattechnical characteristics caused by existence of the cold bridge; Architectural plainness; High logistic expenses.

Transducer Pre- amplifier Signal amplificaiton & Filtering Signal aquisition Signal record, processing and analysis system Analysis the location of AE source Sending AE signal AE source Fig.1 Schematic diagram of AE testing technology Application of AE in material detection AE technology used in metal inspection There are many AE sources in metallic materials, such as crack propagation, displacement, grain boundary sliding, etc.
A large number of studies prove that plastic deformation of metal is the mainly AE source, and AE occur mainly in the stage of yield stress.

The grain size of the abrasive should be larger in the possible, which could increase the cubic of the vacuole in the grinding-driller, convenient for chip reception.
Even for the organization of the grinding-driller, the number of the abrasive should be produced to increase the space of chip reception under the condition of taking shape of grinding-drill.

The fist was commonly used in solid-liquid adsorption system model analysis, the latter was based on the chemical adsorption of rate control steps, and the third happened in rapid agitation intermittent reactor in the adsorption process often belonging to grain internal diffusion control process[5], whose expression for: ln (1-Qt/Qe) = -K1 t (3) T/Qt=1/ (K2Qe2) +t/Qe (4) Qt= Kit1/ 2 (5) Where Qe (mg/g) and Qt (mg/g) are the amount of dye adsorbed at equilibrium and at time t, respectively.
