查询词典 density distribution

Generalized negative binomial distribution was successfully fitted to all the snail data. The parameters of GNBD from the same bottomlands in different seasons changed differently, and parameters of GNBD from different bottomlands in the same season were not similar even if their snail density were close.

不同季节同一滩地间的广义负二项分布参数的变化不一致，同一季节不同滩地广义负二项分布的参数估计结果即使在钉螺密度相近的情况下也不相近，钉螺生存环境的微小差异可以通过广义负二项分布的参数灵敏反映。

It is the objective of this study to use quantitative immunohistochemical techniques to determine increased expression by density and distribution measurements of GAP-43, as an indicator of neurite sprouting.

本研究的目的是通过免疫组化定量技术探讨轴突出芽标志物GAP-43的表达密度和分布变化。加威理由：新人第一帖！

同时，给出了碳化深度的统计特征即平均值、标准差、变异系数统计量和碳化深度正态分布的概率模型及其密度函数。

On the basic of academic function,using the"beeline substitute curve"theory,designed a kind of new probability density function: simplified linear normal distribution function.

在理论分析的基础上，应用"以直代曲"的思想，设计出一种新的简化正态分布函数。

It was related with the real time information about the rolling windows and the distance between the robot and the obstacle. And the normal distribution density function was selected to accomplish to the obstacle avoidance.

通过实时检测滚动窗口内的环境信息，结合移动机器人与障碍物之间的距离关系，利用正态密度函数改变机器人偏转角度，实现避障。

By the minimum risk Bayes decision theory, this paper develops a new way of image segmentation: establish the mathematics model of image segmentation; estimate the probability density of grey scales and figure out its math-expectation and square difference that accord with normal distribution and the loss function; and judge the every pixel dot in the image according to the minimum risk Bayes decision theory and determine whether it is of target or non-target images, thereby realizing the extraction of the target image.

依据最小风险贝叶斯决策理论，提出了一种基于最小风险贝叶斯决策的图像分割方法。首先建立图像分割的最小风险贝叶斯决策模型，对灰度级类条件概率密度估计出其符合正态分布的数学期望和方差以及损失函数，再依据最小风险贝叶斯决策理论对图像中的每一像素点进行目标图像和非目标图像的类别判断，从而实现目标图像的提取。

Three problems can be solved with Hidden Markov Model, they are matching, learning and decoding. In this thesis, we use HMM to develop a system to predict the stock price index. Specifically, we make Gauss distribution as our observation sequence density function.

本文应用隐马尔可夫模型中对于解码问题、学习问题、和识别问题的解决方案，构建包含三个状态的模型，对股票价格指数进行预测。

PE-RT is referred to as the Polyethylene Raised Temperature, it is by the ethylene monomer and 1 - octene copolymer from monomers is specifically designed for the heating system of medium-density ethylene - octene copolymer, which has a narrow molecular weight distribution , octene uniformly distributed in the polymer main chain on the special molecular structure, it retained the original PE performance and processing properties of the health advantages, but also strengthen the durability of a new type of high-temperature resin pipe.
