拔

For the farm, I can never come into contact with, only occasionally listen to my mom said, and truly dried up, before we know it's difficult, I took tools, looked sweet potato vine, running around in circles I do not know where to start, I do secretly aiming a bit students, oh, they have begun to start with, and I've learned to look them in the place near the potato Tengen, I gently dug down with a knock, a knock a knock, careful ah can be Do not give your baby potato gonna hurt, and soon, the red potato on the exposed upper body out, I laughed with excitement, quickly dropped the big knock, just-do, a flexible sleeve, straining for a pull, Hey, how pull it out?

对于农活，我可从来没有接触过，只是偶尔听妈妈说过，真正干起来，才知道它的难度，我拿着农具，看着山芋藤，手忙脚乱不知从哪下手，我偷偷地瞄了一下别的同学，哦，他们已开始下手了，我也学着他们的样子，在靠近山芋滕根的地方，我轻轻用敲挖了下去，一敲一敲，小心啊，可别把山芋宝宝给弄疼了，很快，这个红红的山芋的上半身就露了出来，我乐了，心情极度兴奋，连忙扔下大敲，不管三七二十一，袖子一挠，使劲一拔，咦，怎么拔不出来？

Most of us are used to seeing pull-out sofas for this purpose, but a pull-out coffee table?

我们中大多数人都曾看到拔出沙发的效果，除了拔出一个咖啡桌？

We must see that hydraulic puller is a safe and reliable renewal product for operators, while the traditional pullers are facing the trend of dying out.

我们必须看到液压式拔卸器的问世为操作者提供了安全可靠的更新换代产品，传统拔卸器已面临被淘汰的威胁。

In this paper, the author sets up the dynamic model of the vibratory extracting-driving piling machine, and carries out the dynamic analysis, parameter calculation and Matlab's simulation for this model. Using the equation reciprocity law to carry out the calculation of soil parameter and simulation, and using the genetic algorithm to make optimization of the machine on the basis of the simulation, the author gets the optimum self-induced vibration frequencies of the machine changing with the depth of the pile and the optimization result of other parameters, thus reaching the conclusion that along with the increase of pile sinking depth, the optimum self-induced vibration frequency becomes bigger, and the vibration mass becomes smaller, hence deepening the knowledge of the dynamic performance of this system.

本文建立了振动沉拔桩机的动力学模型并对这一模型进行了动力学分析、参数计算和Matlab仿真，并利用方程对等法进行土壤参数的计算和仿真，又在仿真的基础上使用遗传算法对桩机进行了优化，从而得出了路基加固振动沉拔桩机随沉桩深度变化而改变的最佳激振频率以及其它参数的优化结果，并得出了随沉桩深度的增加，桩机的最佳激振频率由小变大，最佳参振质量由大变小的结论，深化了对该系统动力学性能规律的认识。

Then the foundation base is just like being "unloaded", its bearing load capacity is greatly improved. The rootstalk foundation is suitable and potential especially in deep coverage stratum .

由于根键与土体的紧密嵌固作用，使得基础的抗拔力不再是单纯的侧壁摩阻力，抗拔承载力也得以大大提高，尤其在厚覆盖地层。

Suo one pile, wasteful stationmaster friends are precious time, if your station is in the phase that is depilated, hope if your station is well still,you harvest; somewhat from which in good health, so I also congratulate you, hope at the same time you against a rainy day ready-made, what the mood of Baidu follows summer is showery, say to change; if your station once was depilated by Baidu, that our as it happens with encourage.

啰嗦了一大堆，浪费站长朋友们宝贵时间了，如果你的站正处于被拔毛的阶段，希望你从中有所收获；如果你的站还安好无恙，那么我也祝贺你，同时希望你未雨绸缪做好准备，百度的心情跟夏天的阵雨，说变就变；如果你的站曾经被百度拔毛，那我们正好以之共勉。

The pain-suffering that the toothache that various burning disease causes brings sufferer from go without saying, because of each on the sick list tooth, oneself is all continuously production, made duplicate a great deal of hotbed of germ virus, was passing blood toward the whole body dissemination every day, then violated the whole healthy body, in this time, traditional mouth cavity tooth disease treatment method, have to adopt destructiveness of pulled out a tooth therapyincluded to pull out a tooth, have a tooth filled, root-canal treatment etc.

各种炎症引发的牙痛给患者带来的痛楚自不必说，由于每颗患病牙齿，本身都是一个不断生产、复制大量病菌病毒的温床，每天都在通过血液向全身传播，进而侵害整个身体健康，在这个时候，传统的口腔牙病治疗方法，不得不采取破坏性的拔牙疗法（包括拔牙、镶牙、根管治疗等），来阻止口腔疾病恶化对身体健康的各种不利影响，然而，这种"亡羊补牢"式的破坏性的疗法，却是以牺牲牙齿为代价的。

Results There were 32 patients who undergone tube above five years.One patient of them was pulled out the tube because of papilloma hyperplasia,the other patient was pulled out the tube with the tube slide below,and the rest 30 patients kept the drain well and could tolerant.

结果 治疗32例，观察5年以上，其中1例因结膜乳头状瘤增生而拔管，1例因导管下滑而拔管，30例引流良好，病人亦能耐受。

目的探讨下泪道破坏严重时泪液引流途径。方法在结膜囊-鼻前庭间安置一个内径1mm、外径2mm的特制硅胶导管，此管置于鼻颊沟软组织下，上颌骨前突表面。结果治疗32例，观察5年以上，其中1例因结膜乳头状瘤增生而拔管，1例因导管下滑而拔管，30例引流良好，病人亦能耐受。本文就引流机制、并发症、机体耐受问题和操作进行了详细地讨论。结论泪道外插管是下泪道严重损害时泪液引流的一种较好的解决方法。皮下；结膜鼻腔造瘘术；硅胶导管

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
