估算

Road pricing allows you to very precisely evaluate the benefits of new roads," says Stephen Glaister, an adviser to Sir Rod from London's Imperial College."Some of these schemes have benefit-to-cost ratios of ten to one or better.

公路收费能让你很精确地估算修建新路的收益，&Rod爵士的顾问、来自伦敦皇家学院的Stephen Glaister说，&一些计划的收益与成本比是10比1，甚至更好。

The BVOCs flux from Populus alba × berolinensis, Salix babylonica, Ulmus pumila, Gleditsia japonica, Syringa oblate and Ligustrum obtusifolium in Shenyang were 104.86tC·y-1, 168.66tC·y-1, 3.56tC·y-1, 1.27tC·y-1, 4.07tC·y-1 and 1.33tC·y-1, respectively.

A genetic epidemiologic case-control study including 407 pedigrees(249 cabes and 158 controls)was car-ried out to estimate the segregation ratio and the hereditability(h￣2)of esophageal cancer by using the methodof Li-Mantel-Gart and Falconer,respectively,and to compare the genetic epidemiologic features from theother cancers.

本文通过遗传流行病学病例对照研究，对淮安407个家系（249个先证病例，158个对照），应用Li－Mantel－Gart和Falconer方法分别进行了分离比、遗传度估算及比较流行病学研究。

The bubble point, dew point and critical point were determined for binary mixtures of 1 pentene and 1 hexene, and thus the problem that critical parameters are evaluated without accurate and reliable theory is solved.

测定了1－戊烯－1－己烯二元混合物在不同组成下的泡点、露点及临界点，解决了没有准确可靠的理论估算临界数据的问题。

The higher-order relativistic contribution and QED correction to the energy is estimated under a hydrogenic approximation.

通过引入价电子的有效核电荷，在类氢近似下，估算了对能量的高阶相对论修正和QED修正。

Based on calculating the first-order corrections to the energy from relativistic and mass-polarization effects, we estimate the higher-order relativistic contribution and QED correction to the energy under a hydrogenic approximation. The transition energies, wavelengths and oscillator strengths for the 1s23s-1s2np transitions of this ion are calculated.

在计算相对论效应和质量极化效应对体系能量的一级修正的基础上，通过引入价电子的有效核电荷，在类氢近似下，估算了对能量的高阶相对论修正和QED修正，计算了该离子1s23s-1s2np的跃迁能，波长和在三种规范下的振子强度。

In order to determine flood discharges in rivers without any previous hydrometric record, estimation according to its trace is the only approximation method that is comparatively reliable.

工程设计中，欲在未经水文测验的河流上定出设计用的洪水流率，依据洪水痕迹估算是唯一此较可靠而近似的方法。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
