The results show that, when the volume of the secondary room is 1/3 of that of the primary room,the sound energy decay in the primary room is greatly in- fluenced by the secondary room at an aperture size of less than 10% of the wall,that the energy decay curve and the coupling con- stant in the primary room gradually change with the aperture size,and that the effect of the secondary room on the acoustics in the primary room is uniform.
发现在耦合空间体积与主厅体积比为1/3的条件下,当耦合窗面积与隔墙面积比小于10%时,耦合空间对主厅的声能衰减有较大影响;主厅的声能衰减曲线和耦合常数随开口的改变而逐渐发生变化:耦合空间对主厅各点音质的影响比较均匀。华南理工大学物理科学与技术学院;华南理工大学物理科学与技术学院广东广州 510640;广东广州 510640

In the heredity community renewal process, the paper uses one kind of new crossover operator——Improvement Order Crossover, the better solution two difficult problems both has been able to maintain the fine characteristic of father generation, does not destroy the sub-way which produces already in the most superior routing, and can guarantee when participation in the crossover two individual body is same, causes the genetic algorithms not to be able precociously to restrain in the partial optimal solution.
在应用遗传算法求解时,提出采用惩罚策略处理目标函数中对车辆容量的限制和客户对不同时间窗的需求约束,从而使目标解所对应的染色体能够根据违反约束的程度,具有不同大小的适应度;在遗传群体更新过程中,本文采用一种新型的交叉算子——改进的顺序交叉,更好的解决了既不破坏父代染色体中已产生的最优子路径,还能保证当参与交叉的两个个体相同时,遗传算法不会早熟收敛于局部最优解的两个难题。

In this paper, total logistics amounts are chosen as evaluation index, and artificial time series are designed to solve the shortness of statistical data in Chinese logistics. Spectrum estimation theory depicts time characteristics in frequency domain thus has such benefit than time domain methods. This paper evaluates the period of Chinese logistics using spectrum estimation. Stationarity of artificial series is verified, parameter sensitivity of truncation point is analyzed, six periods with different delay window are compared, and significance of period evaluated is tested.
中国物流统计数据缺乏,客观上限制了对其周期规律的研究,本文选取社会物流总额作为测度指标,设计了一种人工序列,解决了统计数据过短问题;谱估计法从频域角度揭示客观事物的时间特性,在研究时间序列周期波动方面具有时域分析法所不具备的优势,作者采用谱估计法对中国物流发展周期进行测定,检验了指标序列平稳性,分析了截断点参数灵敏度,比较了6种不同滞后窗下周期值,并检验了所测得周期的显著性。
