With an aim at the job-shop scheduling problem of multiple resource constraints, this paper presents mixed self-adapting Genetic Algorithm （ GA ） , and establishes a job-shop optimal scheduling model of multiple resource constraints based on the effect of priority scheduling rules in the heuristic algorithm upon the scheduling target. New coding regulations or rules are designed. The sinusoidal function is adopted as the self-adapting factor, thus making cross probability and variable probability automatically change with group adaptability in such a way as to overcome the shortcoming in the heuristic algorithm and common GA, so that the operation efficiency is improved. The results from real example simulation and comparison with other algorithms indicate that the mixed self-adapting GA algorithm can well solve the job-shop optimal scheduling problem under the constraints of various kinds of production resources such as machine-tools and cutting tools.

对非参数回归曲线提出了一种新的核估计量和窗宽选择方法及修正偏倚置信带。目的是利用该回归曲线的估计量选择窗宽构造置信带.新估计量的拟合精度明显好于Priestley-chao核估计量,新的窗宽选择方法比广义交叉确认准则计算简单;该修正偏倚置信带较优于该回归曲线的Bonferroni型带。用这种方法建立修正偏倚置信带是完全数据驱动,不包含任何附加调节参数,这种方法在实际应用中是十分有效的。

关键词：修正偏倚 Bonferroni带核估计量置信带窗宽

Time-quota is one of important factors in producti on system. It is affected by various factors. time-quota is studied in CAPP and p roduction schedule integration environment in this paper. An agent-based time- quota method is put forward and the structure model is established by means of i ntelligent agent in integrated environment. The method can map the influencing t ime-quota factors into part agent related to process state and machine method a gent, resorting to the function of agent rule-based reasoning, the agents can t ransform these factors into data mode that artificial neural network (ANN) can a ccept and recognize. As a tool, ANN agent can calculate time-quota quickly. A b lackboard method is used as the means of communication and collaborative control between agents. The experiments show that precise process time-quota can be obtained rapidly with proper samples selected, continuous self-study and self -organization in system, and multi-agent approach is an effective method for d etermination of time-quota.

为保证水泥稳定再生碎石混合料(RCR)室内压实与现场振动压实效果的一致性,进行了RCR的振动试验,测试了振动参数对压实效果的影响,对比了振动与击实、静压法确定的压实标准、力学强度、收缩特性和矿料级配衰变的差异。试验结果表明:再生集料(RA)的吸水性、抗压碎强度和洁净程度与天然集料的差异较大;RCR达到稳定振动压实状态的振动时间略大于常规水泥稳定碎石(CSM),但振动频率、名义振幅、激振力和对CSM和RCR的压实效果的影响规律相似,两者可采用相同的振动参数;与击实和静压试验相比,振动试验确定的RCR的压实含水率、干缩变形和矿料级配衰变较低,而最大干密度和力学强度则较高;RA掺量越高,振动试验对于保证RCR的压实效果的优势越明显。

Weinreb first reported the results of transmission electron microscopy observation on ultrastructure of goldfish erythrocyte in 1963. In recent years, there are few reports about the ultrastructure of blood cells in fish For further understanding the fine structure of mature erythrocyte in teleosts, using goldfish (Carassius auratus) as the experimental material We made an observation of the morphology of its mature erythrocyte by means of scanning electron microscopy as well as a study on the ultrastructure by freeze etching technique. Since there are none of reports concerning the study on erythrocyte in fish by using freeze etching technique, the present note will provide here a practical method and the data of studying about ultrastructure of erythrocyte in fish.

关键词： ultrastructure scanning EM freeze ctching erythrocyte goldfish.

压实黏土衬垫是填埋场等环境岩土工程中常用的屏障材料,其厚度和渗透系数是主要的设计参数。考虑渗透系数的变异性,用衬垫底部污染物相对浓度和通量等指标分析了设计参数对衬垫有效性的影响。研究表明,渗透系数的变异性对衬垫性能有很大的影响:当衬垫厚度较小或渗透系数均值较大时,衬垫底部出现高浓度(接近于1)的概率很大,这个浓度区间可能比相对浓度的均值高很多,对周围环境污染有较大的威胁。从非反应性溶质的运移来看,我国规范中对衬垫厚度和渗透系数的规定是合理的。相对于污染物的通量,厚度和渗透系数对衬垫底部相对浓度的影响更为显著,相对浓度更适合作为评价衬垫性能的指标。
