光像

In view of the facts that traditional graphical construction has less pertinence to stray light and tracing different incidence angle rays is fatiguesome and more likely to omit some rays, we proposed a reverse ray-trace method based on the ray reversibility. According to the method, a dot-matrix source was set at the image plane. Each dot emitted rays to fully cover the system aperture. A detector surface, large enough to receive all possible rays from the source, was set at object plane.

针对传统作图法设计遮光罩的针对性不强，且追迹不同入射角的光线繁琐、容易遗漏的问题，本文提出一种逆向追迹法，依据光的可逆性，在像面处设置点阵面光源，每一点都发出充满系统孔径的光束，在物面设置足够大的探测面，使之有充足的余量记录所有到达物方的光线，利用该方法可以在探测面上直观地区分出非成像杂散光。

Its lines are long and elegant; its skin is smooth with the gemlike quality of beautifully tooled metal.

它的线条修长而简洁，它的光滑皮肤像宝石一样，却又像是抛光过的金属。

But the splendid picture of his grandfather, in a perpetual state of rage, bare of head with a black cape which "fluttered behind him like a pair of wings", as he quixotically attacks the prejudice all around him, is worth a mild sigh or two.

而他祖父的照片，看起来总是气愤的表情，光着头，身后的飘动的黑色斗篷&总像是一对翅膀&，就像他以堂吉诃德的方式对抗周围的偏见一样，每每看到总让人禁不住叹息罢了。

不过，他爷爷那苦大仇深，光着头带着的斗篷，斗篷在后面像翅膀一样飞翔着辉煌的画像，那个曾像唐吉珂德般抨击身边一切偏见的人物，确实值得我们为之轻声一叹。

In ring-open form, because of its excellent fluorescence image in living cells, this compound can apply in bioimaging. Also, its properties of restorable and fatigue counteraction can be also well displayed.

在开环态时，化合物具有优良的荧光性能，可以成功应用于细胞成像，在活细胞中可获得清晰的荧光成像图，同时也可以发挥螺吡喃光致变色可循环、耐疲劳等优势。

While I am on the way to the twin falls, Georgie walks to me and inform that she is leaving for Paia now. Oh! Yeah! I would like to go Paia contrast to Twin falls. As Usual, she drives to my destination and drop me off. This time, I am not only sitting in the coffee shop but also strolling the beach. This beach in Paia is very clean. I don't see any trash on it. Also, there are a few tourists surfing unlike Wakiki beach with hundred tourists although today is Saturday. I even see some ladies do sunbathing. There is something funny but weird for me. Foreigners, American and European, are neither afraid of taking a sunbath in the sunlight nor fitting their bra in the public.

准备要走出农场时Georgie正好要出门到镇上去洽公，这时只想当跟屁虫还管什麼瀑布，这次她一样把我丢在网路咖啡厅就离开，今天我没有单单待在咖啡厅，把包包放下点了杯拿铁坐热椅子后，慢慢沿著海滩方向边散步边欣赏周边风景，要把上次忘记走访给补回来，Paia海滩上的沙是白细沙，虽是周末假期但海滩上的游客并不多，不会有像在Wakiki海滩的那种人山人海的盛况出现，且海滩也很乾净没有见到垃圾的踪迹，阿朵仔果然和东方人非常不同，超级喜欢作日光浴，即使被晒的黑抹抹老了会有斑也不在意照晒不误，像我这个见光死的小白犬只敢戴著帽子全身包的紧紧的站在远处偷偷拍照，这还算是小巫见大巫，阿朵仔让我感到夸张的是连当众乔奶也非常的给它不在意，世风日下哦！

Extinction Tomography technique is a new Process tomography technique which is presented and developed recently. It amalgamates the optical measurement technology and the theory of image reconstruction from projection, reconstructs the some parameters distribution of measured field through the modulated effect of measured matter to the light.

消光层析成像技术是近年来提出和发展起来的一种新型的计算机层析成像(Computed Tomography，CT)技术，它将光学测量技术与由投影重建图像的理论相融合，通过检测物质对光的调制效应来重建被测参量场的某些特性分布及参数。
