垂下

This article mainly explains the safety principium of infectant factors in waste water vented by the paper making industry in China. Through the study on the experiment in open country and indoors with soil pole, indicating that it is a complicated process of biochemical degradation to form a layer, which has a biochemical capability to process COD degradation in polluted water from paper making industry.

综述我国造纸业污水中的污染因子危及地下水水质安全的机理，通过对野外试验和室内土柱试验的过程及结果进行分析研究，表明在包气带中形成一个以生物化学作用为主的生化层在造纸污水中COD降解是一个复杂的生物化学降解过程；生化层在天然状态下形成，由生物氧化带和生物氧化还原带形成，其形成过程具有明显的阶段性；只有当生物氧化还原带形成后，生化层才发育成熟，具备对COD降解的生化能力；生化层空间分布，仅局限在污水池、渠底部包气带中有垂向渗流的部分。

The whole goddamned medievalism of the place was infernally ticklish and restive, rocking back and forth with low moans, jumping out at you from the eaves, hanging like broken necked criminals from the gargoyles.

这地方见鬼的中世纪遗风极难对付、极顽强，它低声呻吟着来回摇晃，从屋檐下跳出来向你扑来，像被割断脖子的罪犯那样从滴水嘴上垂下来。

To use isostasy theory, this paper analyzes the causes of the great earthquakes. The loading amount of the Tibetan Plateau is reduced by glacial ablation, the springback of the top of the upper crust is caused. The isostasy is broken and the great earthquake is induced.

运用地壳均衡理论，分析了近年来青藏高原周缘地区特大地震的成因，即随着全球气候的变暖，青藏高原大陆冰川迅速消融，冰川的消融使青藏高原的荷载量突然减轻，触发了下地壳顶面的回弹，进而产生了向上的垂向力，打破了地壳的均衡和青藏高原地壳表层的负载平衡，诱发了青藏高原周缘地区频频发生特大地震。

Open our eyes, we pray Thee, that we may realise fully the low estate of Thy Church and people, and as fully what treasures of grace and power Thou art willing to bestow in answer to the fervent prayer of a united Church.

求你开我们的眼睛使我们真看见你的教会及你子民的光景是何其低落，也让我们看见你所乐意要赐的恩典及能力是何等宝贵。你乐意垂听教会在你面前同心合意的迫切祷告而将这一切赐下。

The mathematic model of the single degree of freedom gyrocompass under electromagnetic bearings is given and the influences on the north finding accuracy and orientation time caused by the declination of the gimbal axis under elastic magnetic bearings are discussed.

提出了一种结构简单的新型磁悬浮寻北仪，建立了电磁轴承约束的单自由度陀螺罗盘的数学模型，讨论了陀螺框架轴在弹性约束下偏离铅垂方向对寻北精度及定向时间的影响。

And the Mathieu's equation, including only the linear coupling term, was also developed.

研究了横摇和垂荡非线性耦合情况下的动力不稳定区问题。

Based on the elastic theory of large deflection and by taking into account the variation of the axial force and its effects on bending deformation of the drillstring in vertical section,the vibration of the drillstring induced by fluctuating weight-on-bit is described by a parametrically excited system.A Mathieu equation describing the system is established by Galerkin Method.By extending the solution into a Fourier series,the curves of dynamic bifurcation values and the dynamically unstable regions surrounded by the curves are presented.

基于弹性大变形理论，考虑到轴力沿钻柱轴线的变化及其对钻柱弯曲变形的影响等因素，将受自重作用的铅垂井段钻柱在波动钻压激励下的振动转化为一个参数激励系统，用Galerkin方法首次得到了描述此系统的Mathieu方程，并通过将方程的解展成富里叶级数的方法，得到了该振动系统的动力分岔值曲线及其所包围的动力不稳定区。

I asked, and the next minute I recognized the odour of the mimosa blossoms.

在温暖的阳光照耀下，开满花朵的树枝几乎垂到青草上。

I studied the angle of his neck, the skin flaps below his chin, the cracked lips and moistness about his nostrils, the pores behind his ears, the wisps of gray hair which crept from beneath the hood of his antique stillsuit.

我 研究了他脖子的角度、他下颚松垂的皮肤、干裂的嘴唇和鼻孔周围的潮湿空气、他耳朵后的毛孔、他穿的古董蒸馏服的兜帽下露出的一缕灰发。
