查询词典 surface of the soil

Research results indicated that the underground biomass changes of three species differed obviously under different traffic treatment. Poa pratensis and Zoysia japonica underground biomass increased at the light traffic then declined. 'Barlexas' Tall fescue decreased with increasing traffic stress. Obvious root shallowing phenomenon is displayed through the increase of roots percent in surface layer and decline in deep layer. Moreover, traffic made the soil density and hardness increase.

洪水冲洗掉地表附近松软的风化土，最终到达了岩床，哥伦比亚高原上坚硬的火山岩。

The excavation surface model of the composition geologic strata for the shield machine was established, in which the soft soil and hard rocks are taken into account simultaneously. In terms of the cutting mechanism of the individual disc cutter and drag scraper, the total bending moment model on the cutterheads of shield machines was proposed. The bending moment behavior was discussed when the shield machine excavates in the composition geologic strata.

针对盾构机在掘进过程中上软下硬的复合地质结构，建立了其刀盘截面圆模型，基于单个切削刀和盘形滚刀的切削机制，建立了复合岩土层掘进时刀盘平面内总弯矩分析模型，分析了与刀盘接触的撑子面内，不同软土面积分数的复合地质条件下，刀盘旋转掘进过程中的弯矩动态特性。

The mission has the right instruments for analyzing soil and ice to determine whether the local environment just below the surface of far-northern Mars has ever been favorable for microbial life.

美国亚利桑那大学首席科学家彼德-史密斯说，火星存在冰的事实并不能说明火星的环境是否适宜生命存在。

Backed by the county Ziwuling Weiwei, small environment humid climate, natural vegetation in good soil plateau surface deep, high organic matter content, non-industrial and mining pollution, the production of the fruit tose yan a big, rich flavor, high sugar content, hardness, resistance and the renowned Quartet storage. Qinguan Apple in 1997, the National Rural fruit fruit variety evaluation at the won the "Huludao Cup" Gold; Fuji apple 1996,1997, Gansu Province, respectively the second high-quality fruit products Thelin Evaluation Council, the first fruit products exhibition Gold rendezvous. 2004, 2005 respectively "Honey Longde card" Trade Marks Registry and the National Green Food Certification.

本县背靠巍巍子午岭，小环境气候湿润，境内自然植被良好，塬面土层深厚，有机质含量高，无工矿企业污染，生产的果品以个大色艳、香味浓郁、含糖量高、硬度大、耐贮藏而享誉四方。1997年秦冠苹果在全国果乡果品综艺品评会上荣获&葫芦岛杯&金奖；红富士苹果1996、1997年分别获得甘肃省第二届名优特林果产品鉴评会、首届林果产品展交会金奖。2004年、2005年分别获得了&陇蜜牌&商标注册和国家绿色食品认证。

我国直到上个世纪九十年代中期才开始使用液压破碎器，随着施工机械化程度的提高，以及对施工工期的严格要求，加上液压锤高效低耗的优点，很快在我国工程施工中推广使用。

The local factors such as topography, vegetations and soil moisture contents, have great influences on the distribution, ground temperatures, and ground ice contents of permafrost. About 50 km of wetlands have been identified along the China-Russia crude oil pipeline route. In these segments, the surficial deposits consist of peat and humic layers on the top of thick ground-ice, or ice-rich permafrost. The frozen ground engineering geology conditions in wetlands generally are the worst for building and operating the pipeline. The hazardous periglacial processes, such as the widespreadpresence of pingos, icings and frost mounds due to the extensive occurrence of the frost-susceptible soils and ample supplies of surface and ground waters in winter pose significant threats on pipeline operation.

地形地貌单元、植被分布、地表水分条件的变化等局部因素对多年冻土的分布和地下冰的赋存产生重要的影响，管道沿线大约分布有50 km左右的沼泽湿地，其表层为腐殖质土及泥炭层，泥炭层下面分布着含土冰层或地下冰，是管道沿线最差的冻土工程地质地段；由于中俄原油管道沿线水系发育多，冻胀丘、冰椎和冰幔等不良冻土现象广泛分布。
