蚁

Red ants carry the larvae into their nests, where they live for the next 10 months feeding on ant grubs, until they pupate and emerge as adults.

幼虫掉在地上，接着就是最奇怪的地方，红蚁把其幼虫扛进巢穴中，在那里它们要呆10个月，靠蚁幼虫为生，直到它们化蛹，成为成虫。

This paper carries out computer simulation of basal ant colony algorithm and reformative ant colony algorithm and also puts up a contrast.

After flow and transient stability calculating of the 330kV grid, we got the over-load and hazard lines set. Then we gained the redundant network needed to be built according to the increasing power supply and load in 2010. Adopting regradation step-by-step algorithm by which we can improve the calculation efficiency , we compared the validity of every line, deleted lines with low validity until no redundant line is in the network. At last we got the target network framework adopting the improved ant colony algorithm. Flow distribution, construction investment assessment and target framework of Gansu long-term planning all be considered, from the viewpoint of to be economic and reliability the feasibility of the improved ant colony algorithm is discussed.

在对2006年该网架结构进行了潮流计算与暂态稳定计算分析后，得出了系统的过负荷与危险线路集，并针对2010年新增的电源和负荷点确定了冗余的待建网架，然后利用逐步倒推法比较各待选线路在系统中的有效性，逐步去除有效性低的线路，直到网络中没有冗余线路为止，以此来以提高优化算法的计算效率，最后利用改进后的蚁群算法确定优化后的目标网架结构，并从潮流分布、建设投资估算等方面与甘肃电网远期规划中确定的目标网架进行了比较，从可靠性和经济性角度论证了改进蚁群算法在网架优化中的可行性。

Red imported fire ant Solenopsis invicta Buren exists in two distinct social forms: monogyne and polygyne.

Abstracts: Finding the major determinants limiting geographical distribution of red imported fire ant, Solenopsis invicta, is an important goal to provide presupposition of implementation a control or even eradication program in China.

进行红火蚁Solenopsis invicta适生性分析，找出制约红火蚁种群发展因素及其潜在的地理分布是开展防控，监管工作的重要基础。

To obtain a comprehensive evaluation of cold hardiness of the red imported fire ant, Solenopsis invicta Buren, the super cooling points of different casts at developmental stages and the ability of workers to survive at low temperature were measured based on materials collected from S.

为综合评价红火蚁Solenopsis invicta Buren的抗寒能力，依据2005-2006年在深圳野外获得的红火蚁自然种群测定了其不同品级及虫态的过冷却点和低温处理后的存活率。

The reduction rates of Solenopsis invicta Buren were above 98.0% at the dosage of 1.0% and 0.5% after 14 d treatment. The values of LT50 against Coptotermes formosanus was 3600 nun with the concentration of 1000 mg/L.

结果表明，0.5%SIOC-I-013对美洲大蠊和德国小蠊的半数致死时间LT50分别为1.61d和1.38d；1%和0.5%SIOC-I-013在药后14d对红火蚁工蚁的减退率均达到98.0%以上，浓度为1000mg/L的SIOC-I-013对台湾乳白蚁的半数致死时间LT50为3600min。

The effects of the invasion of the imported fire ant,solenopsis invicta on the communities of the native ant s were investigated by bait methods in BeiLiu,GuangXi from Sept.

对入侵区与未入侵区比较发现不同生境下，红火蚁入侵使本地蚂蚁的个体数量明显降低，丰富度、多样性和均匀性指数均下降，优势度指数升高，红火蚁成为优势种。

Purpose In this research, we applied three modeling methods to strive for accurately forecasting thepotential distribution of invasive species-Solenopsis invicta in China. Furthermore, we also researchedthe relationship between potential geographic distribution of S. invicta and environmental factors indetail to understanding how environment factors restricted distribution of Solenopsis invicta innon-suitable areas of Chinese mainland. The achievement of research provides a theoretical basis, whichcould guild the next step for the prevention and control stratagem ofS.

研究目的与意义：本研究通过3种不同机理的分析生物分布预测模型进行建模分析，力求准确预测入侵物种红火蚁在中国的潜在分布范围，并明确红火蚁潜在地理分布与环境因素之间的关系，同时找出在中国大陆地区非适生区限制其分布的影响因素。

The method is based on a variable structure to control the SVC, wherein, the variable structure control method comprises two aspects of the unbalanced load equalization compensation and the parameter control of a PI controller, wherein, the unbalanced load equalization compensation adopts the SVC compensation susceptance computational method which is based on the synchronous rotation reference coordinate transformation of a virtual symmetrical three-phase system; meanwhile, in the stabilization control of the system voltage, the ant colony algorithm optimization method is adopted to real time adjust and to optimize the parameter kp and ki of the PI controller.

本发明公开了一种静止无功补偿器的不平衡补偿和蚁群优化方法，基于变结构对静止无功补偿器SVC进行控制，其中变结构控制方法包括不平衡负荷平衡化补偿和PI控制器的参数控制两个方面，其中不平衡负荷平衡化补偿采用基于虚拟对称三相系统的同步旋转参考坐标变换的SVC补偿电纳计算方法；同时在系统电压稳定控制时，采用蚁群算法优化方法，对PI控制器的参数kp、ki进行实时调整、寻优。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
