Fig. 3 Overhanging piezoelectric bimorph in the coordinate system According to the classical description of piezoelectricity[7], a piezoelectric material obeys the following equations (1st-form): S1=s11EX1+d31E3, (1) D3=d31X1+ε33XE3, Where subscripts 1, 2 and 3 represent the directions x,y and z; S and D denote strain and electric displacement; X and E are the independent variables for the stress and electric field; s,d andεare mechanical compliance, piezoelectric constant and dielectric constant.

In order to overcome the above shortcomings, a new method is proposed to identify pigs’ poses by wavelet moment and neural network in this paper. 1 Materials and Methods 1.1 Image edge detection based on ant colony algorithm The discreteness and parallelism of ant colony algorithm is very suitable for discrete digital images.
The provides a theoretical basis and technical support for pig’s gesture recognition and farm intelligent monitoring. 4 Acknowledgements This work was supported by the National Natural Science Foundation of China (Grant No. 31172243), the Doctoral Scientific Fund Project of the Ministry of Education of China (Grant No.20103227110007) and A Project Funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions. 5 References [1]T.Leroy,E.Vranken,E.Struelens,B.Sonck,D.Berckmans.Computer vision based on recogniti- on of behavior phenotypes of laying hens[C].

The rate of loosening of individual particles from the ceramics depends on three factors [6]: The available surface, which means that increasing the volume of macropores (Vmacro>0.1mm) will increase the number of particles released per unit of time, but there was no macropore formed by degradation in our study, shown in Fig 3 and Fig 4; the diameter of the neck, and thus increase with increasing the volume of micropores (Vmicro); the solubility rate (Sn) of the material of which the neck is made.

HUANG Shuang-Ping a*, WANG Xiao-Jia* a School of Pharmacy, Jiangxi Science and Technology Normal University, Jiangxi 330013, China Keywords: 6-bromo-2,3-dihydroxybenzaldehyde, salvianolic acid, synthesis Abstract: The key intermediate, 6-bromo-2, 3-dihydroxybenzaldehyde, of salvianolic acid A (1) was reported, which was synthesized from commercially available 2-hydroxy-3-methoxybenzaldehyde.
The bromide (3) was obtained via a Wittig reaction from the key intermediate (4), which could be got from the commercial available material 2-hydroxy-3-methoxybenzaldehyde (5).[4, 5] In this paper, we just report the synthesis of the key intermediate (4).
The starting material (5) underwent acetylation, bromation, and deprotection to give the desired intermediate (4).

It increases the cost of the experiment because the paper tape is one consumptive material.
Experiment equipment dose not need consumptive material and can save costs.
