The influences of the lumps sizes on the micro-structures , thermal stability，processing fluidity and mechanical properties of the as-fabricated composites have been systematically investigated.
The tensile strength of the product by 15mm×15mm increased by 10% while notched impact strength increased by 22%; The polyester fabric remains fiber structure at the processing temperature (190℃-210℃) and can be used as reinforcements for pp. 1.
The micro-structures, thermal stability, and mechanical properties of composites when the lumps size were 5mm×5mm,10mm×10mm,15mm×15mm respectively have been investigated for the purpose of finding the suitable size to Guide the actual production.

Then, the modeling structure, algorithm, optimization, test and experiment of low-temperature fuel cells were particularly presented applied the electrical characteristics equation.
Schematic diagram of PEMFC structure and principle The PEMFC working principle is shown in Fig.1.
Its goal is to optimize PEMFC structure and test PEMFC performance [5].
As known by the chemical thermodynamics, in the system composed of number i materials, the chemistry potential of the ith material has the following relation with the Gibbs free energy of the system.

A model method based on least square support vector machine (LS-SVM) which directly uses the experimental data is presented to overcome the weakness of mechanism model, and the system structure and algorithm are given.
The internal structure of LS-SVM model is shown in Fig.1.The main idea of the Non-linear regression of LS-SVM is using a nonlinear transformation to map the m dimensions input samples to the higher dimentional feature space F(Hilbert space) from originally space and construct optimal linear regression function.

The structures of these compounds were elucidated as: β-sitosterol (1), daucosterol (2), chrysophanol (3), (-)-epiafzelechin (4), 5,2′-dihydroxy-7,8,6′-trimethoxyflavanone (5) by NMR datas, the antibacterial activity of all compounds were examined on five species of bacteria Escherichia coli, Staphylococcus aureus, Bacillus licheniformis, Pseudomonas aeruginosa and Streptococcus pneumoniae.
Every compound obtained was subjected to detail spectroscopic analys to establish their chemical structures.
The structures of these known compounds were identified by direct comparison of their spectral data (1H NMRand 13C NMR and DEPT) with those reported values in the literatures.
