An abrasive system for use in high cleaning, controlled abrasivity dentifrice compositions comprises at least one abrasive silica which may be selected from a first silica having a Radioactive Dental Abrasion in the range 30 to 150 and a second silica an RDA in the range 100 to 300, and a crystalline aluminosilicate having an average crystallite size below 0.2 mu m.

一种用于高度清洁、控制磨损的牙膏组合物的磨料体系，包括可选自放射性牙齿磨损在30-150范围内的第一二氧化硅和RDA在100-300范围内的第二二氧化硅中的至少一种磨料二氧化硅，和平均微晶尺寸低于0.2μm的结晶铝硅酸盐。

The average desired velocity of the drivers has been assumed to be proportional to the instantaneous velocity by M ndez and Velasco when a alternative model was proposed. Based on this postulate, the desired velocity of a single driver delineates to be proportional to the local instantaneous velocity in this paper, which is a property of aggressive drivers who all want to drive with the maximum velocity. However, the deriver does not occupy this aggressive characteristic all the time.

基于M ndez 和Velasc关于司机平均期望速度与瞬时速度成比例的假设，认为个体司机的期望速度与其局域瞬时速度成比例，期望以更大的速度行驶，然而并非所有的司机都具有这样的进取特性，为了抑制司机这样的进取特性，引入适应性公式来近似表达单个司机期望速度随时间的变化率。

If you're a full-time pro shooter, I have no idea what the M/a mode is, but I have a sneaking suspicion that if it saves you one time out of 20, then of course you'll want this new version.

如果你是一个全职的职业摄手，我不知道什么是M / A模式，不过我有疑虑，如果它能可以帮您获得1/20的机会，那么你当然会希望这一新版本。

The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.

本文主要在以下几个方面开展工作并获得了一些认知和结论：(1)通过分析样带区域内高寒草甸、高寒灌丛、沼泽化湿地和草原化高寒草甸四个通量观测站点草地生态系统总初级生产力变化特征，研究结果表明HBBT矮嵩草草甸生态系统植被光合作用能力较强，年GPP总量为652.2 gC/m~2，明显高于其他三种生态系统；通过利用"单塔日变化法"获得四站点通量观测数据随机误差，结果表明通量观测随机误差概率分布呈现尖峰厚尾的特征，与正态分布相比，更服从双边指数分布，进一步分析表明通量观测随机误差随环境变量(风速、温度和光合有效辐射)的变化而变化，这违背了普通最小二乘法进行生态过程模型参数优化正态分布且误差同质的假设，因此本研究中引入最大似然法进行生态过程模型参数优化。

Thus it indicated that the growing conditions had some effects on the genetic substance of Liquidambar formosana trees when they grew in the conditions of a low altitude for a long time, and when they grew in the conditions with or without sunlight at an altitude of 700 m, although a significant difference occured in the growth of Liquidambar formosana, no obvious difference was found in genetic substance.

这说明长期低海拔的生长环境对枫香的遗传物质有一定的影响，然而在710 m海拔的不同光照条件下，虽然枫香生长表现出巨大差异，但在遗传物质方面却没有发现明显差别。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
