The method which is used to measure and compute moment, yield and turning angle by steel bar gauge is introduced in detail. According to the measuring results, the horizontal critical load of the testing pile is 120 kN. The steel bar gauge measuring results show that the largest moment is located in the depth from 2 m to 3 m under the horizontal load, it transfers to the deeper location with the increase of the horizontal load, and the bend distortion only occurs in the upper of 1/3 pile length.

结合实际工程详细地介绍了利用钢筋计测试水平荷载作用下桩身弯矩、挠度和转角分布的方法，根据桩顶位移和钢筋内力测试结果判定试验桩的水平临界荷载为120 kN；根据钢筋计测试结果可知，在水平荷载作用下，桩身最大弯矩截面位于在地面以下2～3 m处，且随着荷载的增大最大弯矩截面逐渐向深部转移；发生弯曲变形的部分主要是桩长1/3以上的桩体，而其下的桩体几乎不发生变形。

By the field survey which lasting a period of 3 grown seasons and by the means of remote sense and geographic information system, we ascertain the present vegetation pattern of Hunshan-Dake sand land, find out vegetation distribution principles on the different scales in the same time . From west to east, with the increasing of dry degree, the type of plant community changed form the xeric to the mesic. The vegetation of Sand land shows the characteristic of the zonal vegetation, but dont consistent with the traditional diversification principle. The vegetation of the middle part displays a high differential characteristic, which compresses the longitudinal zonation at a certain extent. So we can say that sand land vegetation is semi-zonal.

通过对浑善达克沙地历时三个生长季的地面考察并应用遥感及地理信息系统等手段，确定了浑善达克沙地植被分布现状及浑善达克沙地植被在不同尺度下的分异规律：由西向东，沙地植被随着干燥度的降低，由旱生群落为主的区段递变为以中生群落为主的区段，表现出具有一定的地带性植被特征，但与传统的地带性植被的递变规律不相一致，沙地中段的植被表现出了高度的特异性，在一定程度上压缩了植被的经向地带性，表现出沙地特有的地带性分布规律，所以认为沙地植被是一种半地带性植被。

When the poisonous pesticide is degraded, it is likely pollute soil and water. If the underground water level is within 6 meters to the ground, the eluviated pesticide may pollute the underground water. Thus we have to be cautious when using pesticide

一切的化合物都具有毒素，当施药隐埋后应考虑到农药对土壤、水体降解过程中，药剂施用毒土形成后的向下淋溶径流降解，当地下水位距地面6米范围内时，向下淋溶径流降解的农药就有可能对地下水造成污染，故所应持极其注重态度对待。

The garden, which was slightly arched, had in its centre, on the summit of a hillock, a fine pointed and conical fir-tree, whence ran, as from the peaked boss of a shield, four grand alleys, and, ranged by twos in between the branchings of these, eight small ones, so that, if the enclosure had been circular, the geometrical plan of the alleys would have resembled a cross superposed on a wheel.

园里的地面是微微隆起的，中间有个稍高部分，一株美丽的圆锥形的枞树耸立在那上面，宛如圆盾中心的突刺，四条宽道从那中心出发，伸向四方，每一条宽道又都有两条小路，各向左右分展出去，各各相通，因此那片园地，假使是圆的话，那些道路所构成的几何图形就象一个加在轮子上面的十字架。

Meanwhile , numerical computation of aerodynamics is widely applied with the progress of computer , large quantities of relative paper has been presented . but at present , the relative literature about turbulence characteristics of plural vehicles running in row and passing maneuvers is very limited . pointing to the above difficulty , in this paper , numerical computation of turbulent - velocity field is studied while a sedan exceeding a tractor - trailer truck

本论文在对某国产轿车单车外流场的模拟地面边界层、车轮转动和侧向风载荷研究基础上，以及两辆轿车并列行驶、同向超车的稳态研究的基础上，选取了两种笛卡尔网格方案和四面体混合网格方案，开展某国产轿车超过某大型运输车的数值模拟研究。
