三两个...

There is an assumption that the only way to view a 3-D image is with two eyes and two angles.

有一种假设是，只有这样，才能查看三维图像是两个眼睛，两个角度。

It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

The contents of this paper include three aspects: I Through a large amount of comparison of language resources, to find out the similarities and differences of anaphoric and cataphoric reference in English and Chinese; II From the angle of language system and cultural tradition, analyze the reasons of differences which exist in the two language systems; III One of the important purpose of comparative study is to guide language communication.

本论文的内容主要包括三个方面：一，通过大量的语料对比，找出英汉指称方式的异同；二，从语言系统和文化传统两个角度，分析存在异同之处尤其是不同之处的根本原因；三，对比研究的一个重要目的是指导语言交际，对比语言学研究对翻译活动有何实际指导意义，也是本文探讨的问题之一。

For older adults taking a moderately anticholinergic medication, or two or more mildly anticholinergic medications, their function was similar to that of someone three to four years older.

I am not the beekeeper of the family -- my wife and two of my kids handle that role -- but I've learned some surprising things in the past two or three years.

但在过去的两三年中我了解了蜜蜂身上一些让人惊讶的东西。夏季蜜蜂的寿命平均为六个月。想想看，那意味着每两个月蜂巢就会完成一次自我复制。

For Vitry the breve could be divided , for an entire composition, or section of one, into groups of two or three smaller semibreve this way, the tempus( the term that came to denote the division of the breve) could be either"perfect", with ternary subdivision, or "imperfect" with binary subdivision.

根据Vitry的观点，二全音符在一整首曲子或者其中的一部分中可以被分解为两个或者三个时值短些的全音符组，通过这种方式，这些节拍（这个术语来自于分解二全音符的标识）可以是绝对的三分法也可以是非绝对的二分法。

We also study the generic stability of the solution set of nonlinear complementary problem.In chapter three, we consider the optimization problems and the system of nonlinear equations.

第三章，我们知道，最优化问题的最优解集若能分解成两个或者两个以上的互异的连通区，则没有本质连通区。

One of its expressions is that human society is regarded as a natural historical process. It is because the false way of comprehending it that caused three cognitive mistakes on this Principe. The first one is that the social material system was mechanically analogized the natural material system, which is just like conge and siblings s analogizing human society to the organism of living things. The second one is that the process of social history was mechanically anodized the process of natural history.

正因为对之理解的思维方式的错误，所以导致在这一原理上的三个认识上的误区：一是将社会物质体系机械地类比于自然物质体系，正如孔德、斯宾塞将人类社会类比于生物有机体一样；二是将社会历史过程机械地类比于自然历史过程：三是将社会规律视为预成规律，它表现在两个方面：其一是将社会规律等同于自然规律性，没有看到它们之间的区别；其二是将历史唯物主I，二霎弓。

Go, go, go...Only then at Jiangxi at, eventually Shaanxi Wu Qi, carrying 30 kilograms of heavy blanket roll on the back everyday, on foot more than 30 kilometers -- this is two England youth Li Aide and Mapuan come 16 days from 2 years of 00 2 October 2 3 years 00 on November 3, full 384 days live condition, like a drowned mouse.

走，走，走……始于江西于都，终于陕西吴起，每天背着三十公斤重的背包，步行三十多公里——这就是两个英国年轻人李爱德和马普安从二00二年十月十六日至二00三年十一月三日，整整三百八十四天的生存状态，狼狈不堪。

From research,It is known that the flux of single-phase transformer would offset and exciting current of single-phase transformer would be distorted under DC current inrushing.

直流电流通过两个Y0连接的变压器中性点侵入电力系统，故针对三相三柱变压器直流入侵情况建立了直流入侵下的三相三柱变压器的电路模型和相应的方程，结合三柱磁路的麦克斯韦方程和非线性的B—H曲线方程，利用数字迭代法，在MATLAB环境下编程计算了三相三柱变压器直流入侵下的变压器励磁电流和谐波特征。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
