信息素

Firstlly, architectonic analysis about information hiding detection is proposed, including the analysis of digital image characteristics, image based detecting algorithms and some problems in its realization.

静止图像是像素的集合，相邻像素点所对应的实际距离称为图像的空间分辨率。根据像素颜色信息的不同，数字图像可分为二值图像，灰度图像以及彩色图像。

The edge pixel is processed by Partial Differential Equation. PDE enhances edge and smoothes jaggies in the edge. The pixel in smooth regions of under-interpolated image is processed by Non Local-means model. NL-means model gets gray value of pixel by weighted averaging global information in image and image is smoothed.

使用偏微分方程处理边缘像素，锐化边缘同时平滑边缘块状效应；平滑区域像素点的插值操作使用非局部均值模型，非局部均值模型通过对原始图像全局信息加权平均得到待处理图像像素值，图像平滑。

In the experience mode of remote sensing infor mation inversi on,the discrete data of actual measurement point and the spectrum value that the relative image is corresponding to the pixel,are used to obtain the relation,an d create the remote sensing information inversion module so as to invert the int erested information.

在遥感信息反演的经验模式中，是利用离散的实测点数据与相应的影像对应像素的光谱值找出关系，建立遥感信息反演模型，从而反演出感兴趣的信息。要读出影像上对应点的灰度值，需要先找出相应影像上的对应点的像素行列值。

This paper was studied the derivation of seasonal variation from internal reason variation female sex pheromone and effects of exterior factors.

本文从棉铃虫性信息素的本身是否有变异及外界因素的影响来探讨季节性差异的原因。

When a female is in heat, she sends out a pheromone that can be scented by males for a mile or more.

当一个女性是在热，她发出了一个信息素，可以有香味的男性为1英里或以上。

It introduces the self-adjust pheromone to add intensity coefficient, so that MA can move more efficiently.

在对蚁群算法引入自适应调整的信息素增加强度系数后，Agent能以更高的效率完成迁移。

Some species can detect and respond to pheromone concentrations of as little as one part in a trillion the ''.

有些物种可以发觉含量只有万亿分之一那么少的信息素并作出反应——''。

Insect sex pheromone is a new pest management technique in recent years, it has been one of the IPM important measure.

利用昆虫性信息素防治害虫是近年发展起来的害虫综合治理措施之一。

An improved ant colony algorithm on the basis of ant colony system to solve the traveling agent problem is presented.Ants secrete multi-pheromones to reflect the change of host's service ability and network load dynamically with the results that agent's migration is more agile.

在蚁群算法的基础上，提出分泌多种信息素的改进蚁群算法来求解旅行Agent问题，动态反应了节点服务能力和网络负载的变化，使迁移更具有灵活性。

The effect of sex pheromone trap on beet armyworm was evaluated by setting different densities of traps and comparing with the efficacy of chemical control.

采用不同密度性诱盆处理与常规化学防治处理的对比试验方法，综合评估性信息素防治甜菜夜蛾的作用和效应。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
