The same figure shows also their bivariate population distributions as a function of population density and vegetation fraction.

同样图并且显示他们的二元人口分布作为作用人口密度和植被分数。

In the dissertation, a bipolar coding scheme based on the above feature and a recognition method based on correlation matrix memory are presented.

论文中提出了基于目标主要散射中心之间相对距离分布的双极性二元编码方案和基于相关矩阵记忆网络的目标识别方法。

The model includes 7 groups of urban consumers and 5 groups of rural consumers. The proportion of tax burden of every group consumer to that of the consumer of lowest level income combined with the proportion of governable income of every group consumer to that of the consumer of lowest level income decides the progression of the income tax and the turnover tax.

模型中根据我国的二元经济结构，把城镇居民按收入水平分为7组、农村居民分为5组，运用一般均衡原理，分析流转税税收负担在各组居民之间的分布，再把每组居民承担的税负与可支配收入对比，计算我国流转税体系的具体累退程度。

The element distribution of the homogeneous binary samples withmechanicaly scraped surfaces have been studied by means of Auger-Ion sputteringtechnique.

对均匀二元合金的表面进行机械清洁处理，得到元素深度分布为已知的试样，并对这样的试样做了离子剥离逐层分析。

The CPP was separated into five fractions using fractional precipitations by solvent/nonsolvent technique. Densities for binary mixtures of five fractionated and unfractionated CPP which contains a mass fraction of 30 % chlorine with solvents were determined. At a fixed temperature, concentration and solvent, the densities for binary mixtures of fractionated and unfractionated CPP with solvents have the same value.

用沉淀分级方法对氯含量为30％的氯化聚丙烯进行分级，得到5种窄分子量的级分，测定了氯化聚丙烯的不同级分与不同溶剂组成的二元混合物溶液的密度，在溶剂一定、浓度一定、温度一定时，不同级分氯化聚丙烯溶液的密度是相同的，不受分子量及其分布的影响。

Comparison between the velocity distributions at the different flow rate conditions showed that increasing the flow rate was help to improving the velocity distribution. The periodic mean field on r-6 plane at different axis positions showed that the flow within the vaned diffuser, especially within the inlet region, was periodic unsteady when impeller located at the different circumferential position, just as the flow within the vaneless diffuser.

有叶扩压器内平均流场的分析表明，在定常流动的假设下，不同流量工况下有叶扩压器的内部流动也呈现为沿轴线向后盘方向推移流动状况逐渐恶劣的分布规律，表明二元叶片构成的平行直壁有叶扩压器对轴向不均匀流动的掺混作用仍然不大。

A data set from the ringlet butterfly in the center of Ireland is used to illustrate the method.

同时，我们将应用此结果於二元自我罗吉斯模型以分析在爱尔兰中部蝴蝶分布情形。

Although the asymptotic normality of pseudo-likelihood estimates has been proved (Gidas, 1993), the difference between the proposed asymptotic variance and the sample variance is still huge in binary Markov random fields.

虽然最大伪概似函数估计量的近似常态分布已被证明(Gidas， 1993)，但其近似理论上的变异数与样本变异数在二元随机域之下仍存在著相当的差异。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
