不动的

For a monotone twist map the well-known Birkhoff fixed point theoremsays that the circles with rational rotation number will break up whence a finitenumber of pairs of periodic points arise,half of which are elliptic and the othershyperbolic.Moreover,around each elliptic periodic point a few of new invariantcurves will appear and make a picture of phase space with a self-similar structure.Again one may ask is there a similar picture for higher dimensional Hamiltoniansystems?

对于单调扭转映射，著名的Birkhoff不动点定理指出，在通有情况下旋转数为有理数的不变曲线一般会破裂，在原来的不变曲线附近会产生有限多对周期点，其中一半是双曲的，一半是椭圆的，而在椭圆型周期点的周围又会产生一圈圈的不变曲线，使得椭圆周期点附近的动力学行为和整个相空间的动力学行为十分相象，换句话说，整个相空间具有无限嵌套的自相似结构，自然又产生了一个问题：对于自由度数目大于2的高维哈密顿系统，其相空间是否有类似的图象？

He couldn't have weighed more than 150 pounds, but while working in his yard he carried around big chunks of flagstone that I could hardly lift.

他的体重不可能超过150磅，在院子里干活的时候，那些又厚又重的石板我几乎抬不动，可他却把它们移来移去。

In chapter 4, sufficient conditions of at least one, two and multiple positive periodic solutions to a scalar functional differential equation with muti-finite delays are obtained by using a fixed point theorem introduced in [27] and [85] which is different from the one of a cone compression and expansion of norm type. It generalizes and improves some related results in the literature.

第四章利用文献[27]和[85]中所给出的不同于范数型锥压缩和拉伸的不动(来源：bc1cbcABC论文网www.abclunwen.com)点定理得到了具有有限时滞纯量泛函微分方程至少存在一个、两个和多个正周期解的充分条件，推广并改进了已有的相关结果。

Here (Z_2)~k is considered as the group generated by k commuting involutions.

Don't they know that the entrance to the park lies right next to the 81st Street playground and that if I am not completely prepared, if I do not clear my mind, stop my ears to all sounds other than my own breathing, it is entirely possible – likely even – that instead of striding boldly past the playground with my hands in my pockets and my eyes on the bare gray branches of the trees or on the brown patches of mud and grass, I will collapse outside the playground gate, the shrill voices of the children keening in my skull?

难道她们看不出来我很忙么；难道她们没意识到沉浸在自怨自艾之中的我，根本没心思跟她们说话么；难道她们不知道，公园的入口就在八十一街游乐场的旁边，如果我不做好充足的准备，没理清思绪，没能将所有声音摒弃于外而只专注于自己的呼吸，那么很可能，极有可能，我将无法鼓起勇气，双手插兜，眼睛只盯着枯枝残叶或者一块块褐色泥地和草坪，大步走过游乐场，而是在不断盘旋在脑海里孩子们令人悸动的声音中，彻底崩溃，倒在游乐场的门外。

But Kino's face was set, and his mind and his will were set.

但是奇诺的脸一动也不动，他的心和他的意志也不动摇。

This is why you should never be in a position where it's too dangerous to fall -- with the rope behind your legs, for example, or where a fall guarantees a big pendulum into an immovable object.

这就是为什麼一定不能有一点点时间在危险的状态，例如绳子绕到脚后，或是坠落时会摆荡而撞到不会动的东西。

Test tasks: to check whether the loose connector; hand plate coupling the rotor to move a few laps to see whether rotation and flexible unit, whether there is uneven sound and light and heavy feeling, to determine whether pump or foreign body axis is curved seals, such as the installation is correct; inspection seal on the 20th cavity clean lubricants are added 1 / 2 cavity space; pump unit surface is clean; unit no-load test shift.

试车工作：检查连接件是否松动；用手盘动联轴器使转子转数圈，看机组转动是否灵活，是否有响声和轻重不匀的感觉，以判断泵内有否异物或轴是否弯曲，密封件安装正不正等；检查密封腔内的清洁20号润滑油是否加注1/2腔内空间；泵机组表面是否干净；机组转向空载测试。

This is a partial eclipse of the moon, over-doting mother of the children, the children will eat when food like forever to eat, do not want to eat, one fixed.

这是偏食，妈妈对孩子过分溺爱，孩子就会在吃东西时，对喜欢的食物没完没了地吃，不想吃的东西，一口不动。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
