Build up on the chain can clog the openings on standard roller chain where lubrication enters the pin/bushing area and these contaminants can even get inside the chain, actually damaging the surface of pins and bushings.

在此基础上的链就可能制动标准滚子链在润滑输入 PIN /套面积的开口，甚至可以到达内链，实际上损害了引脚和衬套表面。

Octahedral peak, with an area of about 16 million square kilometers, east-west mountain lanes, from Archaean gneiss composition, the surface of the soil for grass and cinnamon brown earth soil.

Changes of the surface of femoral and tibial condyles cartilage ware observed before and after exercise with scanning electron microscope.

实验评估：扫描电子显微镜下观察训练前后兔股骨和胫骨髁软骨表面形态结构的变化；MIAS99图形处理软件计算浅坑的直径和面积。

In the case of Li, the γ-peak (nitrate and nitrite species on surface) of NO desorption increases, the intermediate N〓O desorbs at higher temperature. In the case of Ce, the α-peak (species on the 〓 acidic sites) of NO desorption decreases, and N〓O desorbs at lower temperature.

对NO吸附在催化剂表面的TPD谱进行了分析，观察到催化剂中加入Li或Ce助剂后，NO的脱附峰面积，脱附峰形状都有明显的变化，Li的加入使NO脱附的γ峰(表面硝酸盐亚硝酸盐物种)明显增加，中间物N〓O脱附温度增高；Ce的加入使NO脱附的α峰减小，而N〓O的脱附温度降低。

Among it wrap up surface auxiliary that cover,-COOH,-OH, sulphur base S032~ sour hydroxyl carboxyl , etc. group last the not facilitating last aluminium the buoyancy of floatings of the powders, and C-C chain , alkyl phenyl R-C6HU fatty alcohol base fatty acid base R-COO, R-0- long in structure, etc. base group kiss not oily, base these group add , facilitate aluminium powder water build rise of area.

表面包覆的助剂中，羧基-COOH、羟基-OH、磺酸基SO_3~(2-)等集团是亲水性的有助于提高铝粉的漂浮力，而C-C结构长链、烷基苯基R-C_6H_(14)脂肪醇基R-O-、脂肪酸基R-COO~-等基团是亲油性的，这些基团的加入有助于铝粉水盖面积的提高。

Water covers about three fourths of the earth's surface and permeates cracks of much solid land.

水覆盖了地球表面的大约3/4的面积，并充满了陆地上的许多裂缝。

Most importantly, enzyme-assisted un-hairing results in a cleaner grain surface and improved area yield and softness.

最重要的是，酶的辅助联合国hairing结果在一个更清洁，颗粒表面和改善面积产量和手软。

To understand the function of such fluid-based adhesive systems, friction forces and adhesive forces of katydids on different surfaces was measured. Construction of the pads and the action of adhesion and detachment were observed through high speed video camera. And the contact area was also tested.

为理解这种基于液体的吸附系统的功能，用在螽斯身上绑细线的方法，测量其在不同表面的摩擦力和吸附力，并用高速摄像机观察足垫的构造及吸附和分离的动作，测试足垫与接触面的接触面积。

The results showed that the soil water contents of sand, A. ordosica and C. korshinskii vegetation in lysimeters all increase due to bitumen felt cover, especially of the CK. The canopy, new branch length and leaf area index also grow in experimental period. But the CK consumes a little water because the neutron probecan t detect the water in gravel layer.

结果表明蒸渗池表面自油毡覆盖至试验结束，油蒿、柠条和流沙处理0～150cm土层土壤含水量都增加，尤其流沙处理土壤含水量上升最明显；油蒿与柠条的冠幅、新梢长和叶面积指数均增加；由于中子仪探测不到蒸渗池底部40cm厚的砾石层的水分，导致了对照流沙处理测定结果不合常规。

The wound surface with scrapers to fight Mao area slightly bigger than the wound.

用打磨机将伤口表面打毛，面积略大于伤口。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
