This text from 艾森斯坦 because of distinguishing the relevant conclusion between method and number theory inside gaved a few and whole coefficient polynomial can't invite of judge the method, discussed at the same time not higher than four times whole coefficient polynomial can invite sex problem, get some three times, four times whole coefficient polynomial can invite sexual and simple judging the method.

本文由艾森斯坦因判别法及数论中的有关结论给出了几个整系数多项式不可约的判定方法，同时讨论了不高于四次的整系数多项式的可约性问题，得到了某些三次，四次整系数多项式可约性的简易判定方法。

Firstly, we prove that if we select nodes properly, and let the distance between these nodes sufficiently small, cubic polynomial spline can approximate a continuously differentiable function, which with continuous derivatives of second order and discontinuity of the first kind in the derivatives of fourth order, to any desirable accuracy. This result lays a theoretical foundation for representing trajectories by splines and double orthogonal basis.

一是证明了适当选取节点并使节点距充分小时，三次多项式样条可以逼近具有二次连续导数的分段四次连续可微函数到足够的精度，这一结论为用样条和双正交基表示弹道打下了理论基础。

In thisstudy, we sought to determine the number of injections neededto provide a reasonably complete anesthesia of the upper limbwith this approach. Seventy-five patients were randomly assignedto receive a coracoid block guided by nerve stimulator with42 mL of 1.5% mepivacaine with a single-injection (Group 1),dual-injection (Group 2), or triple-injection (Group 3) technique.

在本研究中，我们拟探讨为提供完善的上肢麻醉效果所需要的锁骨下臂丛神经阻滞的注射次数。75例病人用神经刺激器指导喙突旁臂丛神经阻滞，随机用1.5%的甲哌卡因42ml 行单次注射（组1）、分两次注射（组2）或分三次注射（组3）。

In order to discuss the rationality of various warping displacement modes, second-degree parabola, cubic parabola, fourth-degree parabola and cosine function are selected respectively. It has been demonstrated that these displacement modes have limitation to some extent, and a more reasonable mode needs to be developed.

为了探讨各种剪滞翘曲位移模式的合理性，分别选取二次抛物线、三次抛物线、四次抛物线及余弦函数等翘曲位移模式进行计算；结果表明，这些翘曲位移模式在一定程度上均存在不足，目前还缺乏一种更加合理的位移模式。

The pencil of plane quadratic lines is the foundation for studying plane cubic curve and hig-her plane curves.

平面二次线束是研究平面三次代数曲线和高次曲线的基础。

In chapter 1,we find out a kind of two-parameter invariant cubic curve family of a certainquadratic system which is important one for studying the distribution of limit cycles.

第二章讨论一般的二次系统具有三次代数曲线同宿环的充要条件，针对问题，我们采用了具有双曲鞍点的二次系统的标准形，利用仿射坐标变换，我们把系统和曲线同时简化，使问题得到了完满解决。

To wipe out the curse of blasphemy, which has increased beyond measure towards a supreme contempt for the divine name and for the saints, we rule and ordain that whoever curses God openly and publicly and, by insulting and offensive language, has expressly blasphemed our lord Jesus Christ or the glorious virgin Mary, his mother, if he has held a public office or jurisdiction, he is to lose three months' emoluments of his said office for the first and second offence, and if he has committed the fault a third time, he is automatically deprived of his post.

要彻底消灭这个诅咒的亵渎，这增加了不可估量实现最高蔑视神圣的名字和圣人，我们的规则和任命，无论谁咒骂上帝公开，并通过侮辱和攻击性语言，已明确地亵渎我们的主耶稣或圣母玛利亚的光荣，他的母亲，如果他曾担任公职或管辖范围内，他将失去3个月的薪酬，他说，办公室第一次和第二次犯罪，如果他已承诺的第三次故障，他将自动被剥夺一切职务。

We had some chances and at the end from the free kick we scored a very good goal.

我们有好几次机会并且在最后的三次射门中我们抓住了一次很好的机会得分。

我丈夫再一次平静地说：这是第二次，我们刚走半里骡子又第三次倒下了。

Do you know, i need you to come back

你知道吗，我需要你回来
