查询词典 pheromone

It modifies the rule of updating pheromones in ACA,so that after every round of search,the increment of pheromone can better reflect the quality of a solution to quicken the convergence;In addition,it uses the heuristic mutation to optimize tours,generate disarrangement effect and avoid precocity.

它修改了基本蚁群算法中信息素的更新规则，使得每轮搜索后信息素的增量能更好地反映解的质量，以加快收敛；另外，它采用了一种启发式变异方法对路径进行优化，以产生搅动效应，避免早熟。

This algorithm is inspired by the foraging behavior of real life ant colonies in which individual ants deposit a substance called pheromone on the path while moving from one point to another.

这种算法是由真实生活和蚁群活动想到的，蚁群中单个蚂蚁在从一点到另一点爬动时的路径。

PBAN regulates sex pheromone biosynthesis in lepidopteran insects.

PBAN的功能是促进鳞翅目昆虫的性信息素的生物合成。

So the application of this sex pheromone provides a new technique for the integrated control of H. hippophaecolus since it is highly effective, nonpoisonous and non-polluting.

用性信息素诱杀害虫作为一种高效、无毒、无污染的新方法为沙棘木蠹蛾的综合防治提供了一条崭新的途径。

The "Y" type olfactometer test showed that sex pheromones in female solvent extract and female volatiles were both attractive to the males, indicating the presence of sex pheromone in female collections. There was no significant difference in attractive effect between two methods of collection.

Y型嗅觉仪测定表明，雌蚊溶剂浸提和空气收集法获得的提取物对雄蚊有引诱作用，且二者引诱效果无显著性差异(P=0.655)，雄蚊对雄蚊提取物无选择性，说明2种方法均从菊花瘿蚊雌蚊提取到了性信息素。

The new algorithm effectively combines the advantages of ACO and PSO. It adopts the grid method for environment modeling and makes use of the efficiency and succinctness of PSO to obtain the initial distribution of pheromone, reducing the number of iterations and accelerating the convergence. At the same time, by using the parallelizability of ants and distributed parallelized-searching technology, the performance of the algorithm is effectively improved.

该方法有效地结合了粒子群算法和蚁群算法的优点，采用栅格法进行环境建模，利用粒子群算法的快速简洁等特点得到蚁群算法初始信息素分布，以减少迭代次数，加快算法的收敛速度；同时利用蚁群算法之间的可并行性，采用分布式技术实现蚂蚁之间的并行搜索，求解精度高等优点，求精确解。

Electroantennogram responses of the generalist parasitoid Campoletis chlorideae Uchida to a range of plant volatiles and host pheromone gland compounds were investigated.

测试了棉铃虫齿唇姬蜂Campoletis chlorideae Uchida对58种植物挥发物和5种寄主性信息素腺体化合物的EAG反应。

We demonstrate that the establishment of a polarized actin cytoskeleton — either as a consequence of normal cell division or through activation of the mating pheromone response — potently attenuates protein synthesis and growth.

他们证明极化肌动蛋白细胞骨架的形成――或者是正常细胞分裂的结果，或者是通过交配信息素反应活化――强烈的减弱了蛋白质合成和生长。

We demonstrate that the establishment of a polarized actin cytoskeleton—either as a consequence of normal cell division or through activation of the mating pheromone response—potently attenuates protein synthesis and growth.

我们表明，建立一个两极化的肌动蛋白细胞骨架，无论是作为一正常细胞分裂，或通过激活交配信息素反应抑制蛋白质合成和增长。

When we conducted a chemical assay of the uropygial preen gland secretions, we found 4 times more volatile octadecanol, nonadecanol, and eicosanol in ratios in males than in females, making them putative male pheromone candidates.

在这篇文章中，研究人员选取全世界最为广泛的笼养鸟和模式实验鸟－虎皮鹦鹉作为实验对象，利用传统的双向选择和GC-MS分析方法，证明鸟类确实存在"性信息素的通讯"。

Do you know, i need you to come back
