First, there are functional cysts, which result when the normal, cyclic development of the ovarian follicles is disrupted.

第一类是功能性囊肿，由正常、周期性卵泡发育过程被打乱而导致。

This protein in turn leads to an overproduction of the intracellular secondary messenger protein, cyclic adenosine monophosphate, or simply cAMP.

然后此蛋白再过度激活一种叫做cAMP细胞内第二信使。

You don't need cyclic dextrin or dextrose or whatever.

您不需要环糊精或葡萄糖或其他任何东西。

So this is cyclic forward and backward movements that the animals make with their whiskers.

所以这是动物用胡须做循环前进和后退运动。

The text intends to tell us that the change of human height follows a cyclic pattern.

文字意在告诉我，身高变化是有规律。

But before we talk about aromatics, let's talk about the most basic cyclic structures, the cycloalkanes.

但在我谈论芳烃之前， 让我先谈谈最基环状结构， 即环烷烃。

But as more carbons join into the ring cyclic structures get more stable.

但是随着多碳入环中， 环状结构变得定。

To know cyclic time's work, if that's your quest, Read Tale of Woes Dispelled on Journey West.

要了解循环时间工作（功效），如果这是您追求，请阅读《西游记》中烦恼消散故事。

Cyclic hydrocarbons that contain resonant structures.

含有共振结构环烃。

And you can't make a ring with one or two carbons, so the simplest cyclic hydrocarbon must be cyclopropane.

而且你不能用一个或两个碳组成一个环， 所以最简单环烃必须是环丙烷。

So far we've just been looking at the cyclic hydrocarbons, so what's up with the aromatics?

到目前为止， 我一直在关注环烃， 那么芳烃又如何呢？

Basically, it has two cyclic structures smushed together and every carbon atom on the ring has another carbon atom hanging off of it.

基上说，它是两个相互铰链环状结构，碳环上每个碳原子都与另一个相连。

If you paid attention, you learned about the structure of cyclic organic compounds and how to name them and their substituents.

如果你留心，你就会了解环状有机化合物结构以及如何命名它和它取代基。

The dormouse can move their whiskers in a process that's called whisking, so backwards and forwards cyclic movements, some of the fastest movements that mammals can make.

睡鼠可以在被称为“摆动”过程中活动它胡须，这样前后循环摆动，这是哺乳动物能做出一些最快动作了。

Now aromatics can have all sorts of substituents as well, and the naming system is pretty much the same as with other cyclics.

现在芳烃也可以有各种取代基，命名系统与其他环状化合物几乎相同。

During puberty, the monthly menstrual and ovarian cycles begin, which is when the endometrium, or inner lining of the uterus, goes through cyclic changes in response to the ovarian hormones.

在青春期，月经和卵巢周期开始出现，此时子宫内膜（或子宫内衬）对卵巢激素作出反应，发生周期性变化。

" If we can get three per cent of the green plant element on Arrakis involved in forming carbon compounds as foodstuffs, we've started the cyclic system, " Kynes said.

“如果我能够在 Arrakis 上获得 3% 绿色植物元素参与形成碳化合物作为食物，我就已经启动了循环系统，”Kynes 说。

The better analogy would be if you're pushing the child on the swing with a cyclic force that has nothing to do with what the swing naturally wants to do.

好类比是，如果您用与秋千自然想要做事情无关循环力将孩子推到秋千上。

Sometimes, they form rings, or as chemists call them: cyclic structures, and if the rings have the right number and placement of double bonds they start acting weird and wonderful.

有时，它会形成环， 或者正如化学家所说：环状结构，如果环双键数量和位置正确， 它就会开始表现得奇怪而奇妙。
