In the bid to increase the diversity of population, MFCMGA uses idiotypic immune network theory to improve the selection operator of SGA. Simultaneously, in order to decrease the randomicity of SGA, the crossover probability, crossover position and mutation probability are adjusted dynamically by using fuzzy inference, which is based on analyzing the heuristic fuzzy relationship between algorithm performance and evolutionary parameters from the viewpoints of environment, population, individual and gene.
该算法利用免疫系统独特性网络学说,改进标准遗传算法选择算子,提高了种群多样性;同时从环境、种群、个体和基因角度,全面分析算法寻优性能和各种进化参数的启发式模糊关系,采用模糊推理动态调整交叉率、交叉位置和变异率,减小了标准遗传操作的随机性。

The results indicate that the different thermal expansions and elastoplastic properties and distributed randomness of various mineral particles composed of oil shale will lead to the nonuniformity of thermal field , deformation field and stress field in heating process , which makes the particles of oil shale deform incompatibly : and the release of product pyrolysis results in irreversible damages of oil shale material and structure . These are the main reasons for the thermal fracture of oil shale .

The results indicate that the different thermal expansions and elastoplastic properties and distributed randomness of various mineral particles composed of oil shale will lead to the nonuniformity of thermal field, deformation field and stress field in heating process, which makes the particles of oil shale deform incompatibly: and the release of product pyrolysis results in irreversible damages of oil shale material and structure. These are the main reasons for the thermal fracture of oil shale. When oil shale is heated through thermal conduction, temperature transfers slowly, so the spacing between heating well and production well should not be kept too long. When difference exists in oil shale reservoir's properties, heating well should be chosen in the high conductivity region. Oil shale's stratification is vital for developing permeation zone in in-situ retorting. Oil shale will generate additional expansion force as it reaches its pyrolysis temperature, and stratification will be cracked first, so the oil shale stratification should be utilized to enhance its permeability.

The two methods had accurate results in forecasting Cricetulus barabansis, but not in Meriones unguiculatus. It was mainly because Meriones unguiculatus population was affected by environment factors at random, and the dynamic tendency was not obvious. It meant that the two time series methods were accurate for the populations which were little affected by environment factors at random.
两种方法对黑线仓鼠捕获率的预测都比较准确,对长爪沙鼠捕获率的预测结果不准确,主要是因为长爪沙鼠种群数量受周围环境因素的影响随机性较大,趋势不太明显,说明此两种时间序列分析方法适用于受随机因素的影响较小,去掉随机因素的影响后有较好的趋势变化的种群。
