廉价

The result indicated that octadecyl isocyanate was successfully introduced onto the surface of the MWNTs,and the dispersion of nanomaterials was thus improved.

结果表明，在MWNTs表面成功地接枝上含有十八个碳原子的小分子，有效提高了碳纳米管在溶液和基体聚合物中的分散性，这种烷基化处理相对简单、廉价。

In this thesis,MWNTs were modified firstly using concentrated acid of H_2SO_4 and HNO_3,and then octadecyl isocyanate was grafted onto the surface of the MWNTs to improve the dispersion and the interaction between the filler and the matrix.

第一步，用浓硫酸和浓硝酸的混合液对MWNTs进行酸化处理，第二步，用廉价的十八烷基异氰酸酯对酸化过的MWNTs进行烷基化处理。

Using silicon and metallic iron,α-Si_3N_4 olivary microparticles with a diameter of about 300～500 nm have been obtained at 650℃.When silicon and metallic aluminium were used to react with ammonium chloride,α-Si_3N_4 nanowire bundles with diameter of about 8 nm can be also obtained at 600℃.Since all of the starting materials used are relatively cheap,the methods will have potential prospect in industrial application.3.Graphite-like carbon nitride nanowire bundles with diameters of 200-500 nm were synthesized from the solid state thermolysis of melamine at relatively low temperature(400℃).

相关研究工作的成果发表在International journal of applied ceramicstechnology.2、以廉价的硅铁合金和氯化铵为原料，在600℃合成了α相的氮化硅纳米线束，单根纳米线直径8 nm，长达800 nm，考察了反应温度和反应时间对产物纯度和形貌的影响；以硅粉和铁粉为原料合成了纯度良好，直径为150～500 nm的α-Si_3N_4亚微粒子；以硅粉和铝粉为原料在400-600℃合成了直径为10 nm左右的α相氮化硅纳米线束。

European immigrants did not only contribute as skilled labors that helped American industries prosper, they also brought with them various religious practices such as protestantism, catholicism and eastern orthodoxism. Asian immigrants brought with them a mysterious oriental culture, in addition to a cheap labor force. The age-old African culture was brought to the United States through salvery trade and legal immigration from Africa.

从欧洲各地的移民除了带来了不需要重新培养技术工人之外，还带来了欧洲各地的文化，清教，天主教，东正教的文化同时在美国存在而来自亚洲的移民除了带来了廉价的劳动力以外，还把神秘的东方文化带到了这里，而非洲原始的文明也随着大量黑奴还有合法移民一同来到这片新大陆。

An interesting fact: Seems humans are hardwired to overconsume energy when it is available.

这是一个有趣的事实：资源丰富时，人类总是超负荷摄取能源，当能源变得又易得又廉价时，我们尽情享用。

An interesting fact: Seems humans are hardwired to overconsume energy when it is available. Make that energy fast and cheap, and we're all over it.

这是一个有趣的事实：资源丰富时，人类总是超负荷摄取能源，当能源变得又易得又廉价时，我们就会将之消耗殆尽。

Instead of prioritizing bandwidth allocation, users can inexpensively overprovision bandwidth when they need to support delay-sensitive traffic such as voice and video.

当用户需要支持对延迟敏感的流量，如声音和视频图象时，他们可以廉价地获得很大的带宽，而不用对带宽进行优先等级分配。
