According to the algorithm, TSP cycle was divided into bicycles randomly, and then the best combination was used to compose a monocycle. In this way, the cycle will converges to optimal solution. The proposed algorithm has been evaluated by simulation experiment using public TSPLIB data.

将TSP环路动态随机分解成双环,再用最佳组合方式组合成单环,实现了在总体路径寻优下的局部路径优化,从而使所得路径尽可能接近最优解。

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.

首次将中生代花岗岩类划分为J2旋回、J3旋回、K1旋回等三个旋回,并依据不同岩石类型间的侵入接触关系,将每个旋回又划分为早、中、晚三期。3、在详细研究区内中生代不同时期花岗岩类岩石特征的基础上,首次将区内中生代花岗岩类划分为碱性系列碱质A型花岗岩类以及钙碱性系列高钾钙碱性花岗岩类和钙碱性花岗岩类等二个系列三种岩石组合类型,确定每个旋回从早期到晚期,岩石均具有从闪长岩、花岗闪长岩、石英二长岩-二长花岗岩-正长花岗岩演化的趋势。4、初步总结了区内中生代花岗岩类的演化特征。

摘要 硝化作用为整个氮循环的必须步骤之一,这一连串的反应主要由自营性的硝化菌负责,因此,自营性硝化菌在氮循环中扮演著关键的角色。

What seems certain is that the nitrogen cycle is changing faster and more profoundly than the carbon cycle, which has attracted much more attention.

看起来有一点是肯定了,那就是,与碳循环相比氮循环改变越来越快,而且影响越来越深,这些已经引起了人们更多的关注。

It consists of nitrogen Brayton cycle, nature gas direct expansion and ammoniawater Rankine cycle.

Based on a comprehensive study of drilling and log data, sequences of short-term base-level cycle of turbidite fan in Yanchang Formation of Triassic in Longdong area are divided into three basic structure types: up - deepening non - symmetry, up -shallowing non ?symmetry and symmetry ones according to recognition sign of the interface of the short - term base - level cycle.

以高分辨率层序地层学理论和技术方法为指导,以钻井、测井资料的综合研究为基础,运用短期基准面旋回界面的识别标志将陇东地区三叠系延长组浊积扇短期基准面旋回层序划分为向上"变深"非对称型、向上"变浅"非对称型和对称型3种基本结构类型。

Based on chapter two, In chapter three, the method of multiple scales is introduced to the study of the multiple-dimensional nonlinear stochastic systems under random external excitation. Using method of multiple scales, we strictly deduce the equation of modulation of amplitude and phase. The effects of random excitations are analyzed; numerical simulations verify the results. Theoretical and numerical simulations show that when the intensity of the random excitation increases, the nontrivial steady state solution may be changed from a limit cycle to a diffused limit cycle.

在第二章基础上,第三章将多尺度法引入到相应的随机系统的研究中;严格推导了系统的约简方程,用矩方法求出稳态解应满足的方程,获得一些结果;并且数值模拟结果与理论推导的结果是一致的;并注意到,与其对应的确定性系统相比较,系统响应从周期解变为近似周期解,系统的相轨线从极限环变为扩大的近似极限环;随着激励带宽的增大,此扩大的近似极限环的宽度将增大。
