Ionosphere can be divided into D layer, E layer and F layer.

电离层又可细分为 D层、E层和F层。

It consists of a two-layer coating of SnO_2:F as an inner layer and TiO_2 as an outer layer.

TiO_2薄膜分别在普通玻璃和在SnO_2：F层上沉积，主要形成的为锐钛矿相。

At the low point of the solar cycle, EUV radiation from the sun is weak and the density of charged particles in the F layer of the ionosphere is least.

在太阳周期的低点， EUV 辐射从太阳是微弱的并且密度荷电粒子在电离层的F 层数是最少。

The F layer is of most importance for HF communications as it is present during day and night, it is located at the greatest height, and it reflects the highest frequencies in the HF band.

F 层数是多数重要为HF 通信照原样存在在日夜期间，它位于在最了不起的高度，并且它反射最高的频率在HF 带。

HF communication generally depends on the reflection of signals from the higher F layer and such signals must travel through the D layer at least twice.

HF 通信一般取决于信号的反射从更高的F 层数并且这样信号必须游遍D 层数至少两次。

Sporadic E occurs at a lower height than the F layer and this tends to limit the distance over which propagation is possible in a single hop.

分散E 比F 层数和这倾向于限制传播是可能的在一棵唯一蛇麻草的距离发生在更低的高度。

Pattern A and B are for the threads. C is created using the noise filter and vertical motion blur. D is another layer of just noise and E is the scaled version of D. F is a layer with random black and white dots. A and B is passed through a distort-glass filter just to give it that random weaving effect.

图案A和B是细线。C的创建是由杂点滤镜和垂直运动滤镜模糊制作的。D是另一层就是杂点，E是对D的放大结果。F是一层随机的黑白点构成。A和B再通过扭曲里的玻璃滤镜得到一个随机编织效果。

It is concluded, that the E2 layer is a normal layer, controled purely by solar ultraviolet radiation; the annual variation of the solar height at the time of first ionization of the E2 layer is irregular, whereas this solar height of the F layer has a regular annual variation.

可以确认，E2层是一个純受太阳紫外輻射所控制的正常层次；該层每天开始电离时的太阳高度年变化是沒有規律的，而F层每天开始电离时的太阳高度却具有有規律的年变化。

Then the coefficients of entrance region effect and the relations between them, and the flowbehaviour index n can be obtained by solving the energy integral equation. Under the assumption of the velocity distribution within boundary layer: f = 1-(1-η)n+1/n for example, co...

以边界层内幂律流体层流速度分布假设f=(1一η)~(n+1/n为特例，所求出的结果与文献[4]中的理论值和实验值比较表明，本文的计算是既简便又可靠的。

The results showed that the concentration of dissolved organic carbon in leachate from fresh litter fall was lower and that from F layer was higher for both plantations. In Castanopsis plantation, DOC concentration declined with the increasing number of leaching times, whereas that in China fir plantation increased at first then decreased.

光谱特征。结果表明，格氏栲和杉木人工林新近凋落物淋出液的DOC浓度较低，F层淋出液的DOC浓度较高；格氏栲凋落物淋出液的DOC浓度基本上随淋溶次数的增加而降低，杉木的则先升后降。

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.

这是凯特，那个是爱朗。
