凸透镜

The boy focused sun's ray on a piece of wood with a burning glass.

这个男孩用凸透镜使太阳光线的焦点集于一块木头上。

But Seymour was "all real things to us: our blue-striped unicorn, our doublelensed burning glass, our consultant genius, our portable conscience…our one full poet."

但是西摩"对于我们来说则是全部的真实：他是我们的蓝带独角兽，我们的复式凸透镜，我们的天才咨询师，我们的是非活手册……我们唯一的大诗人。"

A Galilean telescope is defined as having one convex lens and one concave lens.

阿伽利略望远镜的定义是一个凸透镜和一个凹透镜。

Convex lens and concave lens are two tpyes of familiar lenses.

常见的透镜有凸透镜和凹透镜两种。

Just as a double convex lens enlarges, so a double concave lens reduces.

正象双凸透镜可以放大那样，双凹透镜也可以缩小。

The participants were fifth grade students and they were divided into high score group, middle score group, and low score group according to their achievement in the learning area of science and technology. There were two learning projects in two periods of experimental instruction with different participants: the first project was concave and convex lens and the second project was the investigation of sound and create instrument.

研究对象为国小五年级学生，以学生的自然与生活科技学习成就，将学生分为高分群、中分群、低分群，进行不同研究对象的二阶段实验教学，其学习主题：第一阶段为「凹透镜与凸透镜」，第二阶段为「声音的探讨与乐器制作」。

By using the transfer matrix of the beam propagation,the movement of the low-order nonlinear ghost image s was calculated when high-power Gaussian laser beam passes through the single convexo-convex lens,the single concavo-concave lens and the 4F system and then the movable rules were analyzed.

采用矩阵光学方法，计算了高功率高斯光束通过单个凸透镜、单个凹透镜及 4F系统时低阶非线性鬼像的移动，并分析了其移动规

Secondly, based on the research of the fabric"s contexture characteristic, the author puts forward using the convex shape as yarn"s section, builds the yarns dimensional geometry model and axes equation of warp and weft. Establishes the illumination model which is fit for fabric with illumination theory.

在研究织物组织模拟的基础上，提出以凸透镜形作为纱线截面，建立了相应的纱线空间几何模型和经、纬纱轴线方程；利用光照理论，结合织物的特点，建立了适用于织物的光照模型。

A beam throgh convex lens will be converged, so the lens is also called a converging or positive lens.

凸透镜具有会聚光线的作用，所以也叫"会聚透镜"或"正透镜"。

We can imitate the principles of digital cameras in the scanner, plus a convex lens of the above.

我们可以模仿数码相机的原理，在扫描仪的上面加一只凸透镜。

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。
