It's kind of like the way a lens magnifies a beam of light.

它是一種象一種能放大一束光的方法日韩久久久精品。

Wang's experiment used a very different approach, depending on the way that a light beam is changed by passing through a specially prepared tube of caesium gas.

王的實(shí)驗(yàn)采用了相對(duì)不同于Nimtz的方法黄色一级一区，他測(cè)量的是光束在通過(guò)一個(gè)特別預(yù)備的充滿銫氣體的管子時(shí)候的變化黄色免费在线网观看。

It is shown that beams of reinforced average strain distributing accord with flat section assume; The method of strengthening intension of concrete structure with reinforced materials is a feasible way. The strength of beam can be increased with the number of reinforcement materials be added; The strength of beam is affected by percentage of flexural reinforcement and the compound proportion and fashion of reinforcement materials and the number of reinforcement materials; The capability of bend and stretch and price of inner hybrid fiber is better than sole fiber and exterior hybrid fiber.

通過(guò)分析可知：加固后的梁国产精品2022免费无码视频，其平均應(yīng)變的分布符合平截面假定日韩A片一级无码专区网址；使用加固材料來(lái)提高混凝土受彎構(gòu)件承載力的補(bǔ)強(qiáng)加固方法是有效的；構(gòu)件受彎承載力隨加固材料用量的增加而提高亚洲综合免费；縱筋配筋率又大又硬又粗视频网站免费观看、加固材料混雜比例及混雜方式美女污疼视频网站、加固材料用量均對(duì)受彎承載力有一定的影響；層內(nèi)混雜纖維的抗彎性能欧美性免费、延伸性能以及經(jīng)濟(jì)性均優(yōu)于單一纖維和層間混雜纖維黄色在线网站视频。

The specificity of the surface gained in this way is that when the beam of rays parallel to its axis of rotation falls on it, the beam is reflected so that all the rays meet in one point, known as the focus, in the same way that optical lenses focus light rays in their focus.

拋物線的表面或曰拋物面，是由拋物線圍繞其對(duì)稱軸旋轉(zhuǎn)而成A性视频AAA，其特點(diǎn)是日韩精品视频热线在线观看，和拋物線對(duì)稱軸平行的射線波束被拋物面所反射，所有的電波都在同一點(diǎn)匯聚www.噜噜噜， 1 September99看黄，2009 3D 角反射天線作饋源的 5.8GHz 偏饋拋物面天線我們把這點(diǎn)叫做焦點(diǎn)。

Place the specimen in the spectrophotometer with its cylindrical axis parallel to the slit and in such a way that the light beam is perpendicular to the surface of the section and that the losses due to reflection are at a minimum.

將樣品放入分光光度計(jì)老妇女棚户区卖淫对白视频，使其圓柱軸與狹縫平行国产交换配乱婬视性色aV，這種方式可以使光垂直照射在樣品的表面上并使光反射的損失最小。
