中节

In Chapter 4, there are two important structures, loops and stacks for an abstract single-strand RNA. Based on the method of combinatorial enumeration, we make a new discussion about the enumeration problem and get its approximation with the limited length of end loop.

第三部分：RNA二级结构是由一些环和茎组成的结构，在此基础上，本节以端环中自由基数为参量，我们又利用组合技巧解决了一类RNA二级结构的计数并给出了它们的近似值。

In section 2, we give the notion of M-valuation systems for a commutative ring, and establish some basic results on M-valuation systems.

在第二节中，给出了M-赋值系统的定义，并给出了相关的结论。

Fortunately, there is an IC called a comparator: these come usually 4 sections in a single package.

幸运的是，有一个IC称为一个比较：这些出现在单一封装中通常为4节。

All the people is who you meet in your whole life is in the same compartment.

在同一节厢的乘客都是你一生中相遇到的人。

In this section, we will see how to configure SVN for all these access methods.

本节中，我们可以看到如何为SVN配置所有的这些访问方式。

To further reveal the structure of monocotyledon lignin, carbon 13 enrichment of specific carbons of rice stalk lignin was achieved by feeding coniferin [α 13 C], coniferin [β 13 C] and coniferin [γ 13 C] into an internode cavity of the stalk of a growing rice plant Oryza sativa L.

为了进一步了解单子叶植物的木素，向生长中的水稻(OryzasativaL 。)茎秆节间的腔体分别注入在侧链α、β、γ位带13 C标记的松柏醇葡萄糖甙，得到侧链带13 C标记的稻秆木素。

In this lesson, you will learn how Japanese verbs conjugate.

在这节课中，你会学到日语动词如何变形。

The control inputs guarantee the asympototical stability, and the global existence and uniqueness of solutions for the initial value problems of systems under some consistency conditions also.

第二节，我们将变结构控制的思想应用到一类带变秩系数阵的线性时变广义系统，以确保系统运动过程中出现的新的相容性条件的满足，从而确保系统初值问题解的整体存在唯一性。

In the third section,we study the relationship between the APOTP for continuous map / on a compact metric space X and that for the lift map / of / on a covering space X and show that has the APOTP if and only if has the APOTP.

在第四节中，我们研究逆极限空间上移位映射的APOTP，讨论紧致度量空间上连续映射APOTP与逆极限空间上移位映射APOTP间的关系。
