The soil erosion process on the slope was clearly divided into sheet erosion stage, rill erosion developing stage and rill erosion stable stage. Before lOminutes of rainfalls, the percentage of sheet erosion amount to total erosion amount was more than 90%, and it indicated that sheet erosion happened on the slope. This percentage sharply decreased before SOminutes of rainfall time, on the other hand, the percentage of rill erosion amount to total erosion amount increased in curve form with rainfall time.

在降雨前10min左右，面蚀贡献率约占坡面侵蚀总量的90%以上，为面蚀阶段；随着降雨时间的延续，面蚀贡献率先急剧递减最后在第30min左右基本达到稳定，细沟侵蚀贡献率则出现相反趋势，此为细沟发育阶段；降雨后期，面蚀和细沟侵蚀贡献率的变化趋势逐渐变缓且基本达到稳定。

The flatness quality problems such as sidewise bending and warping usually appear in hot rolled sheet product. Residual stress distribution of hot rolled steel sheet before and after straightening was obtained by modified hole–drilling technique, in order to improving the quality of hot rolled steel sheet product.

本文针对热轧钢板产品常出现的旁弯、翘曲等板形质量问题，通过盲孔法测量钢办矫直前以及粗矫、精矫后的残余应力分布来分析矫直工艺对带钢残余应力分布的影响，以便改善热轧钢板产品的质量。

If the dial indicator reads 0.14~0.3mm , it means the tooth clearance is right; You can also use a 15~20mm long and 0.5mm thick lead sheet or "∽"-shaped fuse . Put the sheet or fuse between the unengaged tooth flanks tha is between the convex surface of small bevel gear and the concave surface of the large bevel gear. Turn the gear, then the pressed thickness of the big lead sheet end suggests the normal tooth clearance of this site.

另一种方法是用长15~20毫米，厚0.5毫米的铅片或弯成"∽"形的保险丝，放入两齿轮非啮合的齿面之间（即小锥齿轮的凸面和大锥齿轮的凹面之间），转动齿轮，则铅片在靠近大端处被挤压的厚度即为该处的法向齿侧间隙。

A circle shear machine for cutting holes and rings in sheet metal whereby the sheet metal is held stationary by a pair of coaxially aligned and opposed center shafts which are each provided with a thrust bearing mounted support platform to engage top and bottom surfaces of the metal sheet at the locus center of the hole to be cut.

一个圈剪切机切割孔及戒指在钣金，而金属板材是静止举行，由一对同轴不结盟和反对的中心轴，这是每提供一台推力轴承安装支撑平台，以进行顶部和底部表面的金属板材在轨迹的中心孔被削减。

Models are built according to the emersed part and floating part of the ice sheet, respectively. Bending moment distribution in the ice sheet is analyzed to determine where a bending failure may occur. The analytic solution of breaking length for ice sheet is obtained.

文中将冰排分为在斜面附近脱离水面部分和较远处漂浮于水面部分两个区域，建立了冰排因弯曲而发生破断的数学模型，根据弯矩分布分析了冰排可能的破断位置，从而得到冰排与斜面结构相互作用时的破断长度解析表达式。

Foreign atoms were placed over the sheet at several symmetrical positions, namely, over a carbon atom, over a C-C bond, over the center of a pentagonal, hexagonal, and heptagonal ring. The following conclusions have been drawn: The cohesive energy of adsorbate and perfect sheet at all three adsorption sites is always lower than that on a sheet with a Stone-Wales defect embedded at all five sites.

得到的主要结论如下：所有外来原子在含有Stone-Wales缺陷的石墨烯片上不同位置上吸附的结合能都大于在其在完整石墨烯片上不同位置上的结合能，因此在碳管中引入Stone-Wales缺陷能够提高原子在碳管上的吸附能力，同时提供了很多稳定的吸附位置。

The only current ice sheets are in Antarctica and Greenland ; during the last glacial period at Last Glacial Maximum the Laurentide ice sheet covered much of Canada and North America, the Weichselian ice sheet covered northern Europe and the Patagonian Ice Sheet covered southern South America.

格陵兰冰原将全岛覆盖，仅在狭窄的边缘有少量岩石露出。因为动、植物贫乏，故有人将格陵兰的冰原称为&冷荒漠&。南极洲冰原不但将全陆地覆盖，而且有些地方扩大至海上。冰原的厚度有些地方可达数千米。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
