Cycles of heat to break apart the DNA strands, cooling to allow the primers to bind, and heating again to allow the enzyme to copy the intervening sequence, lead to a doubling of DNA at each cycle. 循环升温分离DNA双链,降温使引物结合,再升温使酶能复制DNA。这样每一循环产生双倍DNA。
And you know, you could have a reversible engine with lots and lots of steps, but you could always break them down into some sequence of adiabatic and isothermal steps. 你们知道,我们可以设计一个由,很多很多个,循环步骤的热机,但是总可以把它分割成,一系列的绝热,和等温过程。

Our goal is to take problems and break them down into these computational steps, these sequence of instructions that'll allow us to capture that process. 我们的目标是得到问题,然后将问题分解为这些计算步骤,这些指令集,可以让我们看到这个过程。
The comprehensive analysis of sequence stratigraphic framework in this sag by applying sequence stratigraphy and slope break theory suggests that the third class sequence is the most basic reservoir-cap unit, and the southern Taibei sag is the most favorable area with non-structural traps. 应用层序地层学和坡折带理论,对台北凹陷中浅层层序地层格架进行了综合分析,指出三级层序是最基本的储盖单元,凹陷南部是非构造圈闭发育的最有利地区。
Study on depositional shoreline break for terrigenous sequence stratigraphy along the steep slope zone of Fault-depressed Lacustrine Basin 断陷湖盆陡坡带陆相层序地层的沉积滨线坡折问题探讨
Lowstand system tract, lacustrine transgression and highstand system tracts in the interest area can be subdivided by the repeated pattern of stratigraphy, locally distribution of coal-bearing measure and the location of topographic break in sedimentary sequence. 以地层叠置样式、局部分布的煤层以及地形坡折带在沉积层序中的位置,细分出低位、湖侵和高位体系域。
But a large number of literatures on this subject mostly discuss the concept related to fault components from the view of application, like Power-frequency Variation, break variable, positive sequence fault components, fault-generated transients, etc. 但大量的文献多是从应用角度讨论故障分量、工频变化量、正序故障分量、负序故障分量、零序故障分量、暂态故障分量、突变量等概念。
A new application of graph theory for determination all of the break point sets is put forward, and then the sequence of setting coordination of back-up relays in network and the relationship of the main/ back-up protection are obtained. 提出了一种新的基于图论的确定系统所有最小断点集的方法,并由此得出网络后备保护的整定配合顺序和主/后备保护关系。
