光点

Under the optimized conditions, the relative fluorescence intensity decreased linearly with the copper ions concentration in the range from 2 to 200μg·L~(-1) and the detection limit could reach 0.29μg·L~(-1). Based on the charge-transfer quenching mechanism, the copper ions bounding onto the surface of qdots could absorb electrons from valance band, which results in the quenching of fluorescence.

用电荷转移机制解释了量子点荧光猝灭的原因，主要是由于价带电子激发到导带以后被表面结合的Cu~(2+)离子捕获而产生的结果，在此基础上，用光解实验进行了进一步的验证。

You're a carousel, you're a wishing well, and you light me up when you ring my bell.

你是一匹旋转木马，你是一个美好的愿望，当你向我鸣起钟声时你同时也点亮了我的生命之光。

The heritage that impressionism gave to modern man is more than just vivid colors; what is more important is that it opened a door for the expression of individual and diverse art. After that, cubism shattered classicalism's mirror of the single perspective.

印象派绘画带给现代人的遗产不仅仅是光鲜的画面颜色而已，更重要的是它开启了一扇通往表达个人的多元化的艺术之门，在此之后立体主义砸破古典主义单点透视这唯一的一面镜子。

I am experiencing this kind of feeling now: Another name for Guangdong Province of Mu of channel of admonish show off is planted the flame that? of armour of Xin Chun Tuo cannot find outlet; to discover far has a very small amount from beginning to end however, running over to look is the wildfire on animal body however there is a few dazzled to glimmering all round; green light, the whoop that accompanying loud and jarring ignore far ignore close... good, too good to avoid you moral nature takes a phone to dial 110, I must admit, I did not search savage in divine clothes tree, never also track Hua Nahu; in Shaanxi town level ground I am to sit before computer merely, cudgel one's brains for, think hard, pray god can save me from inside inspirational and dried up lair come out, good let me write to still calculate pretty good column.

我现在正在经历这种感觉：在黑夜的丛林中往返奔走，却始终找不到出路；发现远处有一星半点的火光，跑过去一看却是动物尸体上的磷火；四周有几点荧荧绿光，伴着粗重的喘息声忽远忽近……好吧，为了避免你过于好心地拿起电话拨110，我不得不承认，我并没有在神衣架寻找野人，也不曾在陕西镇坪追踪华南虎；我仅仅是坐在电脑前，绞尽脑汁、冥思苦想，祈祷上帝能把我从灵感枯竭的泥潭中拯救出来，好让我写完一篇还算不错的专栏。

When I is a two-dimensional matrix, then I is the intensity value at the position corresponding to row r and column c of the matrix.

设I是一个二维矩阵，则I就代表行r列c点的光强值。

In the roof reconstruction, a TIN-based region growing is applied to extract the roof planes. The coplanarity and adjacency between triangles are considered for TIN-based region growing. Then, a least squares regression is selected to determine the coplanarity function of planar segment.

在建物屋顶面重建中，使用建物轮廓线内部的光达点云进行屋顶面之共面分析，研究中使用三角网区域成长法侦测共平面之屋顶面，以相邻三角网法向量夹角做为共平面门槛，并以最小二乘法回归出屋顶面之平面，产生房屋模型。

Analysis results show that the measurement error caused by the small change of beam cross angle can be neglected.

研究了补偿OEHF—LDA测量点移动的光学方法，并分析了光束角度变化对测量精度的影响，在此基础上提出了OEHF—LDA的光路设计方案。

The measuring device is structured by including a He-Ne laser; a beam expander, a soft aperture slot and a off-axis parabolic mirror to be measured are arranged in turn along the direction of the emergent laser beam direction of the He-Ne laser; a standard cross hair and a micro objective are arranged in turn on the direction of the reflected beam of the off-axis parabolic mirror; the micro objective is arranged on the focus of the off-axis parabolic mirror; the focus is imaged on an area array CCD; the output end of the area array CCD is connected with a computer; the off-axis parabolic mirror is fixed on a five-dimensional electric adjusting frame.
