查询词典 trapping

In order to solve this problem, this paper proposes an enhanced Boot-Trapping algorithm.

为了解决这一问题，本文提出一种改进的启动接入算法。

At the early iteratives, the mutation rate is bigger and the aim is to make particles to explore smaller and isolate region and to avoid the algorithm trapping to the local optimum. While the algorithm runs, the mutation rate will be decreased to reduce the disturbing to the particles. IPSO adopts a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space. Additionally, our algorithm incorporates a mechanism with a simple and easy penalty function based on the largest distance between the particle and the boundary of the feasible region to handle constraint.

IPSO采用了一种新型的变异策略，变异概率随着算法的运行是动态变化的：在算法运行初期，变异概率大，其目的是使算法不但能够探测到目标空间中的孤立区域，而且避免搜索陷入局部极值；在算法运行后期，变异概率逐渐变小，以减少对粒子的扰动；算法通过将部分具有邻近距离的粒子聚集成核形成多子群引导种群中粒子的飞行；采用一个简单的基于粒子与可行域边界最远距离的罚函数处理约束的机制，使得算法高效实现。

The development of trapping devices is felicitous proof of adaptive evolution.

Two-thirds of the atmospheric buildup of carbon dioxide, a heat-trapping greenhouse gas that can persist in the air for centuries, has come in nearly equal proportions from the United States and Western European countries. Those and other wealthy nations are investing in windmill-powered plants that turn seawater to drinking water, in flood barriers and floatable homes, and in grains and soybeans genetically altered to flourish even in a drought

大气中2/3积聚的二氧化碳——一种能在大气中留存几个世纪的滞留热量的温室气体，美国与欧洲更正为西欧）国家差不多各占其一半的排放量，它们与其他富国正投资建设由风力发电设备驱动的将海水淡化为饮用水的工厂，同时还在投资建设防洪堤、水上漂浮住宅、以及能在干旱条件下生长的转基因谷物与大豆。

As she spoke, a low-pitched rumble could be heard in the distance. It was a backhoe, futilely picking through the shell of a factory dormitory that had crumbled, trapping dozens of people.

她正说着是，远处传来低鸣的隆隆声，原来是一个挖掘机徒劳地在已经倒塌的工厂废墟中搜寻着，其中有几十人被埋。

The sexual behavior of chrysanthemum gall midge, Rhopalomyia longicauda (Diptera: Cecidomyiidae) such as the release of sex pheromone and calling behavior, were studied indoors and in a field trapping experiment. The sex pheromone was collected with an organic solvent aided by a glass container of charcoal-purified air. Laboratory observations showed that most males emerged 1-2 h before females.
