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。

During the infiltration process of indirect subsurface drip irrigation, the ponded water depth changed from zero to a constant and accelerated the water movement in the vertical direction, which reduced the discrepancy of wetted distance in lateral direction and vertical direction, while the changed water depth had small influence on the wetting front movement in vertical direction to upward and downward. The shape of wetted soil zone was spheroid, and its symmetry axis lied near the bottom of the water conducting device.

间接地下滴灌灌水过程中，从零开始逐渐增大并趋于稳定的积水深度加速了水分在垂直方向的运移，缩小了横向湿润距离和垂向湿润距离之间的差异，但变化的积水深度对湿润锋在垂直方向向上和向下的运移速率影响不大，使湿润体形状表现为扁率不断减小的椭球体，且椭球体对称轴分布在靠近导水装置底部的位置。

As she trekked to the parking spot, she ruminated about her latest acquisition, the pink chiffon skirt, envisioning floating into the office garbed in it , exquisitely shod in a pair of pink princess shoes , definitely low-heeled, with her hair loosely wound in a solitary thick plait to the side and the end of the plait done up in a style that is loose and deliberately taking it to one side but looking as nonchalant as if it were not deliberately done, that chaste and alluring appearance will, without a doubt, captivate Chen's heart.

她一边向车位走去，一边想着新买的那条粉色连衣裙。想象着自己穿着它，妩媚地步入办公室，脚上踩一双粉色公主鞋，一定是要一公分左右低跟儿的；及腰的长发，斜斜地编一根独辫，发根处要略微蓬松的那种式样；再特意将麻花辫拿在身前来，仿若无心似的，轻轻垂下一侧裸露的肩头。那清纯娇妩的模样，定然会打动沉的。

He played it left hand But made it too far Became the special man, then we were ziggy's band David Bowie Ziggy really sang, screwed up eyes and screwed down hairdo Like some cat from japan, he could lick 'em by smiling He could leave 'em to hang They came on so loaded man, well hung and snow white tan. So where were the spiders while the fly tried to break our balls Just the beer light to guide us, So we bitched about his fans and should we crush his sweet hands?

他用的左手，但伸的很长成为一个特殊的人，我们是杰基乐队杰基深情地唱着，闭上眼睛垂下头发像一只来自日本的猫，用微笑抚慰人们他能让他们暂时停歇他们承受重压，长期等待，肤色雪白苍蝇在破坏我们的舞会却不见蜘蛛的影子只有昏黄的灯光引导着我们我们要辱骂他的歌迷，毁坏他美丽的双手吗？

All of London's theatres switched off their marquees at l0pm for an hour of respect and requiem masses were arranged in New York,A memorial service was held at St Martin's in the Fields on August l4th,attended by her many friends and famous stars,Many felt for her to die while she was still performing and beautiful,was how she would have wished it.

十点钟，所有的伦敦剧院垂下遮檐一小时，向她致敬。纽约举行了安灵弥撒奠祭。八月十四日，在菲尔兹的圣马丁举行了追悼仪式，生前众多的朋友和明星前来参加。许多人认为，她在仍然美丽、仍在表演的时候离开人世合乎她生前的愿望。

By the early '80s, however, her own career was in trouble -- 1982's Green Light, while greeted with the usual good reviews, again failed to break her to a wide audience, and while beginning work on the follow-up, Warners unceremoniously dropped her.

到80年代初，但是，她自己的事业遇到了麻烦- 1982年的绿光，而与平常的善良再次未能打破她给广大观众评论，欢迎，虽然开始的后续工作，华纳兄弟毫不客气地垂下。

Even in this brief epitome I ought to say that all who departed for the provinces across the sea, whether proconsuls or governors appointed by the emperor, went out of their way to see him at Rhodes, and on meeting him they lowered their fasces to him though he was but a private citizen — if such majesty could ever belong to a private citizen — thereby confessing that his retirement was more worthy of honour than their official position.

即使是在这部简史中，我也要说，所有跨海赴任的省督，无论是代执政官级的还是皇帝钦命的总督，都要绕道罗德岛来拜访他。会面时，尽管提比略不过是一介白丁——假如这样的贵人也能被叫做白丁的话——他们都要垂下其&法西斯&，由此而证明他在隐退之后比起这些在任的总督仍更值得尊敬。

The traveller was a thickset, square-shouldered, yellow, wrinkled old man, with grey eyelashes overhanging gleaming eyes of an indefinite grey colour.

过路客人是个骨骼宽大、皮肤发黄、满面皱纹、敦敦实实的老头，他那炯炯有神的浅灰色的眼睛上面垂下斑白的眉毛。

But suddenly, as we struggled round a bend,there would be a glimpse of rush walls, of peaked grass roofs, a burst of yells, a whirl of black limbs, a mass of hands clapping, of feet stamping, of bodies swaying, of eyes rolling, under the droop of heavy and motionless foliage.

然而，当我们奋力转过河弯时，会突然瞥见那静静垂着的浓荫下拥挤的墙垛，尖尖的草屋顶，许多黑色的肢体在旋转，许多眼睛在骨碌碌转，还会听到爆发出的呼喊声，许多手的拍击声，许多脚的跺地声。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
