反转

In compressional area, physical modelling has been proved to be a powerful tool for simulating the evolution process of fold-thrust system, and gets great progress in nappe and double thrust structures, thrust belt inversion and basement involvement, compressional orogenesis function and surface process, structure transform zone in compressional area and mantle convection together with collision or subduction of plates etc.

在挤压地区，构造物理模拟已经被证明是一种模拟逆冲褶皱系统演化过程的强有力工具；在推覆体或双冲构造、冲断带的反转与基底卷入、挤压造山作用与表面过程、挤压地区构造转换带及地幔对流与板块碰撞俯冲等方面取得了很大进展。

It was found for the first time in b-FeSi2 based thermoelectric materials that a p-type semiconductor could change to an apparent n-type one, when the temperature was decreased below a critical temperature.

本项目研究首次在b-FeSi2基热电材料中发现"热伏极性"反转现象，即p-型半导体在某个临界温度以下表现为明显的n-型半导体热电特性。

The group disposed by Acetylspiramycin doesn"t show parallel results; The strip gray scale of exotoxin A decreased gradually with the increasing dosages of Azithromycin and Roxithromycin, which doesn"t show in group disposed by Acetylspiramycin and group PAO-JP2; The strip gray scale of lasR, detected by RT-PCR, decreased gradually with the increasing dosages of Azithromycin, which doesnt show in group PAO-JP2.Conclusions: There were obvious differences between PAO1 and PAO-JP2 in biology characteristics in vitro.

本研究发现大环内酯类药物在生物被膜培养过程中分别处理PAO1、PAO-JP2，结果提示大环内酯类药物(14、15元环)通过对QS系统的影响可有效抑制铜绿假单胞菌生物被膜的形成；通过QS系统有效抑制铜绿假单胞菌的毒力因子的产生，16元环的大环内酯类药物乙酰螺旋霉未见上述结论；lasR基因的反转录结果提示阿奇霉素可在转录水平抑制QS系统发挥其作用。

In Saintpaulia ionantha, actinomorphic peloria was raised in domesticated cultivation from the zygomorphic wild type.

然而，苦苣苔科的野生型园艺植物非洲堇(Saintpaulia ionantha， African violet)原本野生型的花是两侧对称，但在人择栽培后有反转为辐射对称的变异型出现，这给予我绝佳机会探讨在同一种植物中花部对称性转换的分子机制。

But it's the overall lack of visibility that has left analysts penciling in anything from 'W' to 'L' shaped recoveries, to a rather more optimistic 'U' or 'V'.

不过，总体透明度的不足令分析师莫衷一是，既有"W"型和"L"型的复苏，也有更为乐观的"U"型或"V"型的反转。

When a pennant flies in the direction of the trend, it is usually followed by a sharp reversal.

当一个旗形沿着趋势的方向飘扬时，通常后面就会发生强烈的反转。

For instance, head and shoulders tops or bottoms, pennants or triangles often show up on the index to indicate breakouts and buy and sell points.

例如，头肩底/顶、旗形或三角形常常会显示在指标上提示出反转以及卖点和买点。

If we introduce the aperiodic or periodic reversal of the nonlinear optical coefficient into the waveguides, the CSHG conversion efficiency can be improved greatly, the configuration also has been called quasi-phase matched CSHG. Several research work in this filed has been carried out.

如果引入二阶非线性系数的周期极化反转，即考虑到准相位匹配的情况，切伦科夫倍频效率将会得到极大的提高，可以将之称为准相位切伦科夫倍频。

给出了周期反转永磁聚焦系统的设计方法和设计考虑，讨论了控制极调制多注电子枪设计中遇到的特殊问题和解决方法，建立了计算电子光学系统的二维磁场和电子轨迹计算软件，并应用这些软件设计和研制了S波段200kW多注宽带速调管的电子光学系统。

The rule of cycing is investigated, and the phase diagram is depicted.

给出了这种反转态出现的相区，并且观测了其动态转变的规律。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
