Abstract:Rights control is the central part of MIS(management information system) security management .Common rights control which bases the character and the operator can resolve the One-dimension rights management.Rights control based on the operator leads to the large workloads, the operation becomes unpractical when it is dealing with those units that are big and multiclass. On the other hand, rights control based on the character can release the workloads but it also brings us the confusion of duties and the data operation. The model and the practice of Two-dimension rights control are mentioned.The key property is the rights' self-maintenance of the units and the operators. It strongly supports the least work of the DBA(Database Administrator), insure the security of database and the exclusive DBA in the system. The two-dimension rights control has been used in the road transportation management system for 4 years by 42 units all over the Chongqing City with high praise of the users.

Abstract:The traditional storage of tree data structure is according to the relation of the elements' frant-and-back. Since it is difficult to define the frant-and-back relation of graphics units in CAD for Engineering structure, the application of the tree structure becomes inconvenient. The authors change the storing method for the tree structure into gradation and classification. And a graded equivalence relation of graphics units is brought forward, which grade the graphics units with the equivalence relation. By using this storing method, we can easily accomplish some operations, such as picking up the subtree with a certain character, deleting a node, insert a graded and classified node, etc. The example provided indicates that the storage by gradation and classification can speed up searching and process the data of the subtree by gradation and classification expediently. This kind of storing method for the tree structure is applicable for data which contain the graded equivalence relation.

The experiment result indicates that the saturated adsorptive quantity of clinoptilolite in the static state is 3 100 mg/100 g,when the concentration of ammonia nitrogen is 35 mg/L, the saturated adsorptive quantity in the dynamic state is about 2 200 mg/100 g, and was 20, 23 and 27.5 times of the pulverous active carbon's, the granular active carbon's and the diatomite's respectively. The mixed solution of NaCl+NaOH (the weight proportion is 3:7) could be repeatedly used three times as the regeneration reagent of clinoptilolite, and the effective life is exceeded 140 h. Clinoptilolite has important practicality when it is used to dispose the wastewater containing ammonia nitrogen.

Abstract:With reference to the effect of the quadratic component of turbulent-wind fluctuation, the statistical moments of wind load up to the 4~(th) order are derived and the spectrum densities are given based on the Fourier transformation. By means of the Gram-Charlier series, the first-order probability densities of the structure responses are then constituted with the former 4~(th) order central moments of responses. Under the independent hypothesis of the structural displacement and its derivative, whose applicability is verified by the correlation between the two signals, the joint probability density function is developed and a numerical scheme for the analysis of the dynamic behaviors of the high-slender structure under wind excitation is obtained. Parametric analysis on dynamic responses and reliability under both Gaussian and non-Gaussian models of wind load are then investigated.

The experimental results show the filtration flux steadily increases with the working pressure in the range of the working pressure lower than 0.2MPa; the filtration flux decreases with the concentration of the raw water at the constant working pressure. The lower the organic substance of raw water is the higher the filtration flux is. Linear regression method is applied to the experimental data, and the UF membrane flux model is presented. Meanwhile the model can be used to design UF process for similar liquid mixture system.

Abstract:Initial return and short-term return are two totally different conceptions. When the anticipated year return is evaluated, we should stand on the conception of short-term return not the initial return. Based on the primary conception of the investment return, and considering the cost of purchasing, this paper gives the method of calculating the rate of short-term return. After the experienced analyses, we think there is excess return in the primary market. However, influenced by the low hit rate, only those investors, whose capital over some limit, can get it. The result explains the phenomena that why little investors leave the primary market for the secondary market. From the other way, the result proves that the investors are rational.
