The hydrogen atomic protonized model was introduced in present paper for calculation of H2+ structural parameters. The dynamic equilibrium between Coulomb attraction and inter-nuclei repulsion force was discussed respectively from macro- and micro- time scale, and it is suggested that the charge barycenter, e/8, formed at the midpoint between two nuclei by distortional electron-clouds of hydrogen atoms, could astrict a naked proton. Three formulas deduced from above model for bond-length, bond-energy and force constant of hydrogen molecule ion were Re=2a0, 
. When atomic-unit used,they are respectively Re= 2au., De=0.109735au. and k=0.109735au.，which are satisfactorily accorded with the experimental values and Bishop's most accurate calculated values (Re= 1.997 735 336au.，De=0.102 375 331au.,k=0.102 896 975au.).

The order-picking optimization of single-line fixed shelf similar to the symmetric and asymmetric traveling salesman problem is analyzed and proved. Then a new modified Lin-Kernighan (LK) algorithm is studied and applied it to the order-picking processes of the fixed shelves. The results of simulation indicate that the algorithm can reduce the computational complexity of time and space greatly, and also can find out the optimum solution quickly and steadily. The variation of the number of the order-picking points in wide range required by different tasks can be satisfied as well.
A new method using accelerating rate calorimeter (ARC) was introduced in this paper to evaluate the thermal stability of energetic materials. By the method, the adiabatic decompositions of ammonium nitrate (AN) and non-explosive and irrestorable fertilizer-grade ammonium nitrate (NEIFAN) were investigated. The curves of thermal decomposition temperature and pressure versus time, self-heating rate and pressure versus temperature were obtained. The kinetic parameters such as apparent activation energy and pre-exponential factor were calculated. The effects of thermal inertia factor on the results of measurement of the adiabatic ARC are discussed. It was indicated that NEIFAN has better thermal stability and safety. At the same time, it can be shown that the elimination of NEIFAN explosive characteristic is due to the improvement on its thermal stability.

The Putaohua reservoir in Taizhao area is the typical low-permeability reservoir which developed EW, SN, NW and NE tectonic fractures with high angles in the periphery of Daqing Oilfield. The development degree of above four group fractures in succession die down. By effect of modern stress field of approximately EW direction, the connectedness, opening and permeability of EW fractures are the best, then are NW and NE fractures, and that of SN fractures are the worst. The development degree of fractures are controlled by lithology, thickness, fault and tectonic stress. The effects of fractures on development include pattern arrangement, injecting water and fracturing. According to geological condition and numerical simulation of oil pool, the development effects of similar low-permeability reservoirs by rectangle and lozenge well pattern are better than by inverted 9-spot well pattern and 5-spot well pattern. Due to development of fractures in low-permeability, the stratum cracking pressure reduces, which is liable to be exceeded by the injecting pressure. This will make injecting water to flow fleetly along fractures, and cause water flooding, influenceing development effect. Therefore, it is very important to control injecting pressure in the development of low-permesability reservoirs. The artificial fractures are controlled by the modern stress field and natural fractures in fractured low-permeability reservoir. According to fractures and their seepage characteristics, three sets of adjustment schemes can be adopted on the basis of existing inverted 9-spot well pattern. At the same time, good effects can be obtained by early mild injecting water, controlling injecting pressure, linearity injecting mode, dynamic preparing water, pulse cycle injecting, perfecting pour and pick system, well pattern adjustment, choosing fracturing well and controlling fracturing scale, etc.

On the basis of analyzing characteristics of the central air-conditioning system, a fuzzy controller with self-optimizing parameters is proposed and applied into the temperature control of the system. To deal with the non-linearity, time delay and time variation of the controlled system, a method for optimizing the weighting factor a and the output scaling gain Ku is adopted in the applied rule-adjustable fuzzy controller. The experimental result indicates that the optimization method enhances the robustness of the fuzzy controller. As the temperature of the cooling water and the temperature of the circumstances change, the controller maintains satisfactory performance.
