RBI Grade 81 stabilized layers have been proven to be very durable and wear resistant, and meets the standards required by the Norwegian Public Roads Administration to resist extreme climate and permafrost conditions, and thus the goal of being able to modify a gravel/dirt road to function much like a tar road in all weather conditions can be achieved at a fraction of the conventional cost.

使用RBI 81级产品稳定的基层已被证明具有非常持久、耐磨的特点，满足挪威公路管理局要求的承受极端气候和冻土条件的标准，因而可实现将砾石/泥土道路改造为和沥青道路一样可在任何气候条件下使用的目标，而其成本仅为使用传统修筑方式的一小部分。

When negative numbers are defined,we might define negative fraction numbers,and so we have all rational numbers,and might define operations on them,discuss operation laws.

在引入负数后，我们可以继续定义负分数，得到所有的有理数，定义有理数的运算，讨论运算律。

Taking operation of rational numbers as the carrier, this paper starts the research right from the study on multiplication of decimal, division of fraction and multiplication of rational numbers and studies the "understanding levels of operation of rational numbers and the teaching and learning strategies that matches them."

本论文以有理数运算作为载体，选取小数乘法、分数除法和有理数乘法作为研究的切入点，研究了&有理数运算的理解水平及其教与学的策略&，具体说来，研究了3个问题：(1)学生对有理数运算的理解达到怎样的水平；(2)学生达到某种理解水平的原因是什么；(3)基于学生的理解水平，有效的教与学的策略是什么。

With LAT, color-accurate accurate proofs can be made on the actual substrate in minutes in an all-digital workflow at a fraction of the cost, with a quick turnaround.

在拉脱维亚，色彩准确准确的证据，可实际在几分钟内底的全数字化工作流程上的一小部分费用，以快速的转身。

But when the pressure is bigger than 30MPa, there is a contrary phenomenon. The flow rate, particle size distribution and void fraction of the extraction bed have the complicated effect. 3Based on the broken-intact cells model, a dynamic model based on differential mass balance equation is developed according to the law of conservation mass. The expression of mass transfer flux is given by the analysis the process and the necessary hypotheses. The extraction process is described, and the expression of extraction rate of diosgenin is given.

3在引入破碎—完整细胞结构理论的基础上，根据质量守恒原理建立了基于微分质量守恒方程的动力学模型，通过对萃取过程的分析和必要的简化、假设，给出了不同阶段传质通量的表达式，在此基础上描述了萃取过程，并给出了超临界流体萃取薯蓣皂甙元的萃取收率表达式。

But even in the sedimentary rocks only a tiny fraction of prehistoric plants and animals have left any record of their existence.

但即使是在沉积岩石中，史前的植物和动物也只是留下了它们很少一部分遗迹。

Now for a limited time, you can get this video at a fraction of the price of a one-hour lesson with yours truly.

现在，在一段有限的时间，就可以享受这部影片在一小部分的价格，一小时的课，与你真正的。

The Western half of North America, according to agronomists, is losing its fresh water supply so quickly because of glacier melt that they will face severe rationing within 10 years and absolute shortages -- to the point where, as happens now in many struggling nations, the water supply will only be turned on for a hour per day, and each household and enterprise will be limited to a fraction of what we now use.

据农艺师们说，北美的西半部正由于冰川融化在很快的散失淡水资源。他们在10年内将会面临严重的水资源短缺，重点是现在在很多欠发达国家水每天只能开一个小时，每个家庭，每个公司也都被限制在我们现在的用量的一部分之内。

The shaping method of noncircular part and the tool holder's radial motion characters in noncircular turning process are discussed in detail in the thesis.
