In order to get the more accurate data of atmospheric capacity about this type of area, such as Yueyang, this paper analyzed the characteristics of Yueyang meteorology, gathered the features of atmospheric pollution sources, worked out the main problems in environmental protection. In addition, we analyzed the rule of atmospheric transport and diffusion, and took the Frequency of lake and breeze to modify the data of atmospheric capacity of Yueyang, which was achieved by A-P index, and compares the modified data of atmospheric capacity with the data of atmospheric capacity achieved by multi-source. The results indicated that according to the fact of lake and breeze, taking the frequency of lake and breeze to modify the data of atmospheric capacity of the field with stable lake and breeze, which is achieved by A-P index, made the atmospheric capacity more accurate. Accordingly, the result could be more reliable if the modified data is taken to calculate the atmospheric capacity when we assess the impact on the environment of the field with stable lake and land breeze.

Using the concept of Boolean functions and combinatorics theory comprehensively, we investigate the construction on annihilators of Boolean functions and the algebraic immunity of symmetric Boolean functions in cryptography:Firstly, we introduce two methods of constructing the annihilators of Boolean functions, Construction I makes annihilators based on the minor term expression of Boolean function, meanwhile we get a way to judge whether a Boolean function has low degree annihilators by feature matrix. In Construction II, we use the subfunctions to construct annihilators, we also apply Construction II to LILI-128 and Toyocrypt, and the attacking complexity is reduced greatly. We study the algebraic immunitiy of (5,1,3,12) rotation symmetric staturated best functions and a type of constructed functions, then we prove that a new class of functions are invariants of algebraic attacks, and this property is generalized in the end.Secondly, we present a construction on symmetric annihilators of symmetric Boolean functions.

The formation process of the rocks is divided for thefirst time into three cycles corresponding to J2, J3, and K1, respectively, and each cycle into early,middle, and late periods based on intruding contact relationship among different types ofgranitoids.3. A detailed study on the petrological characteristics of different cycles of theMesozoic granitoids supports classification of the rocks into three lithological associationsincluding A-type, high-K calc-alkaline, and calc-alkaline granitoids, of which the first associationbelongs to alkaline series, and the others belong to calc-alkaline series. It is shown that thelithologies change from diorite, quartz monzonite, and granodiorite to monzonitic graniteand syenogranite with periods from early to late in each cycle.4. A preliminary summarization hasbeen made on the evolution characteristics of the rocks.
