  absolute density
The growth exponent for the minority is related to its absolute density and temperature because of its small density.
      
We present systematic studies on the absolute density of hydrogen cluster beams produced by using Laval-nozzles.
      
It is assumed that, for those prey animals whose percentage in the total prey of a predator is fairly high, the percentage proportionally approximates the real fluctuations in their (absolute) density.
      
Our results clearly demonstrate that absolute density is a poor predictor of roe deer performance and supports the view that habitat quality has an overwhelming importance for determining fawn body mass in roe deer populations.
      
In three patients with chronic obstructive pulmonary disease and in one healthy subject, absolute density of selected lung regions was measured in the supine position by the Compton scatter technique.

  intrinsic density
Here, we investigate the relative importance of intrinsic (density-dependent) and extrinsic (climatic) factors impacting the dynamics of a tree frog (Hyla arborea) population over 22?years.
      
The penetration depth of the lowest capillary mode is consistent with the interfacial thickness as determined from the intrinsic density profile, and the data for the higher modes suggest that the penetration depth might be independent ofk.
      
This intrinsic density of heterogeneous nucleation sites is sufficiently high to promote the formation of fine, interlocking AF laths in the weld metal during they- to- a transformation.
      
Because T decreases with depth, irreversible density stratification is favored, even for small intrinsic density contracts.

A modified Support Vector Machines (Modified SVM) for non-parametric estimation of density function,which is a modified version of Support Vector Machines (SVM) for non-parametric estimation of density function,is discussed.This procedure is based on the prior knowledge that the probability of any event decides the number of samples which indicate the happening of that event in probability theory,specifically,the larger probability of an event,the more number of samples which imply the happening of that event.A better outcome is obtained by Modified SVM than that by SVM in the simulation.What's more,since the problem of the estimation of density function is ill-posed,the regularization method is adopted.

讨论密度函数的非参数估计问题,提出了一种修正的支持向量机(SupportVectorMachines,简记为SVM)方法,修正SVM法是在SVM方法的基础上进行简单改进而得到的,它是基于概率理论的概率大的事件其对应的样本数目会比概率小的事件的对应的样本数目多一些这一先验性质而产生的,这样估计的函数能更好地近似真正的密度函数.同时,由于密度函数的估计问题是不适定的,文中密度函数估计采用了正则化技术处理这一估计问题,最后通过一模拟实验,表明采用修正SVM法比采用SVM法进行密度函数估计能更好地逼近真实密度函数.
