As a bionic sense technique, the AITS is composed of three parts, namely the cross-sensitive sensors and their array, self-study specialist database and intelligent recognition. The voltammetric and the potentiometric techniques are two main test methods. The sensitive materials include noble metals, rare earth metals, lipids and lipids polymer, chalcogenide glass materials, conductive polymers and other materials such as graphite paste, phthalocyanin, Prussia blue etc. The PCA and the ANN are the primary pattern recognition tools in intelligent recognition.

The results show that the effect of small-sized hole and delaminations is not great . On the natural frequencies , the effect of t ransverse elliptical multiple delaminations around an elliptical cent ral hole is more serious than that of lengthways elliptical multiple delaminations around an elliptical cent ral hole ; the natural f requencies are very sensitive to damages location , and less sensitive to multiple delaminations' size and the holes'size.

Our results showed 1 The changes in trends of leaf traits response to the rainfall gradient differed either with species or with a specific trait; 2）The same trends were found at the functional group level, However, leaf traits for grasses tends to be less sensitive, then for forbs, and the legumes is the most sensitive functional group along the rainfall gradient, indicated that the Grass function group is quite strong to the soil moisture content tolerance, and which certainly explained to the local vegetation distribution and the substitution between species.

During the fracturing for low pressure and low permeability gas reservoirs, there are some main problems in conventional hydroxypropylguar - organic boron cross-linking system: Firstly, the water-lock damage to low pressure and low permeability gas formations by filter liquor; Secondly, the reason for alkali-sensitive damage in alkali-sensitive reservoirs is that conventional hydroxypropylguar - organic boron cross-linking fracturing fluids were cross-linked under alkaline environment, while the permeability of reservoirs is reduced greatly; Thirdly, the formation pressure is low, and the energy of flow back is not enough, at present, the main measure in oil fields is "injecting with liquid nitrogen", but this technique increased the cost of fracturing, making great troubles in operating, and leaving the liquid nitrogen also is a big problem.
