For easy to install and checkout optical instrument,here primarily introduces the basic principles and structure component of collimator,which is composed of object lens、divisional board and ground glass.

1引言根据几何光学原理，无限远处的物体经过透镜后将成像在焦平面上；反之，从透镜焦平面上发出的光线经透镜后将成为一束平行光。

Objective To explore the feasibility of functional magnetic resonance imaging in analysis of olfaction function with modified OEP-98C olfactometer and event-related design.

目的探讨以改进后的OEP-98C型嗅觉诱发电位仪作为嗅觉刺激器，事件相关设计的嗅觉功能磁共振成像分析嗅觉功能的可行性。方法采用改进后适应磁共振环境的OEP-98C型嗅觉诱发电位仪作为嗅觉刺激器对6名右利手年轻男性志愿者进行嗅觉刺激。

This model adapts the prior information of piecewise continuity of image to construct a nonlinear diffusion model,which is used to smooth an enlarged image by nearest interpolation to reduce the blocky effect caused by enlargement,simultaneity,and interpolation condition is added into the iterated process to avoid a too smooth image.

新模型利用图像为分片连续的二维曲面的先验信息，采用非线性扩散方程对基于最近邻方法放大后的图像进行光滑以消除因放大引起的"块状"效应，同时在迭代过程中加入插值条件使处理后的图像能较好的保留边缘，由此构造出基于偏微分方程的图像分辨率增强模型和相应的迭代算法，使图像的分辨率增强到亚像元级。

Results In 108 splenic preservation cases, who were operated or non-operated, the value of 1gM and CD3 was significantly higher than that in the splenectomy group (P.01); CD8 and CD4 were significantly higher that those of splenectomy group (P.05); the percentage of pockmark red cells was lower than that splenectomy group (P.01) CT, BUS and 99mTc nuclide scan confirmed that the structure of the preserved spleen had recovered to normal, and the ruptured surface of the spleen had completely healed I mouth after operation.

结果 108例保脾患者经手术或非手术治疗后，其IgM，CD3远高于切脾组，差异有显著性(P.01)；CD8和CD4显著高于切脾组(P.05)，痘痕红细胞百分率低于切脾组(P.01)。CT，B超，99锝核素显像等证实保脾组1个月后脾结构恢复正常，裂口创面完全愈合。

Second, Wu dialects, like Mandarin, are of both prepositions and postpositions, but the postposition system in Wu dialects is more advanced than in Mandarin in that there are richer highly grammaticalized postpositions and they play more active syntactic roles in Wu dialects than in Mandarin.

二、吴语像普通话一样前置词和后置词并存，但后置词比普通话更为发达，表现在语法化程度更高、在句法结构中的作用更重要。

In many ways, reclassification may be compared to changing colors on a map , in that the reclassified attributes may plot out in new colors.

在钗h方法中，重新分类常被比喻成在地图上改变颜色，而重新分类后的属性就像在地图上的改变后的新颜色。

Firstly, the digital watermarking was transformed randomly, and then encrypted by chaos. The encrypted watermarking was transformed to one-dimensional row vector, and the pixel value was sorted. The coefficient of primitive image of stationary wavelet transformation was expanded to one-dimensional row vector, too, and then the sorted watermarking was embedded to the sorted low frequency and turned to two dimensions.

本算法先将数字水印图像进行置乱变换，然后将置乱后的水印图像进行混沌加密，将加密后的水印按行展开成一维行向量，并将像素值从大到小排序，将原始图像平稳小波分解得到的低频系数也按行展开成一维行向量，并按从大到小排序。

After arriving at Australia, uses the lunch, latter tours Macao each big scenic spot, including the Sao Paulo church vestige big three Pakistan memorial arch, Macao's origin and the most ancient temple Mazu Chinese style pavilion, Macao gambling establishment, the prosperous times lotus flower, looks at the sea Goddess of Mercy elephant, the Venice person resort and so on.

抵澳后用午餐，后游览澳门各大名胜，包括圣保罗教堂遗迹大三巴牌坊、澳门的起源及最古老的庙宇妈祖阁、澳门赌场，盛世莲花、望海观音像、威尼斯人度假村等。

A short-lived and undoubtedly 'fantastic' stint was brought to an end after The Doctor sacrificed himself, just like his fifth incarnation, to save his companion. Cellular degeneration and regeneration into Barcelona-bound David Tennant ensued once he sucked out and absorbed the Time Vortex from Rose Tyler's mouth. Has anyone else ever found a better pretext for a sloppy snog?

在一句"fantastic"后，博士牺牲了自己，就像他第五个肉身一样，为了拯救他的搭档；从Rose Tyler嘴里吸出时间漩涡能量后，华丽丽地重生为DT版博士；对于这个庸俗伤感的吻，还有谁能找到更好借口吗？

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
