Based on the normative fractional Fourier transform and the concept of the optical transfer function, using the linear system theory, the mathematic expressions of fractional transfer function in Fresnel diffraction system and Fraunhofer diffraction system are given respectively.

基于规范光学分数傅里叶变换，从光学传递函数概念出发，根据菲涅耳衍射、夫琅和费衍射定义，应用线性系统理论，分别给出了菲涅耳与夫琅和费衍射系统在规范分数傅里叶变换下的光学传递函数数学表达式。

In this thesis, several basic principles and phenomena of the Wave Optics are first intruducted briefly, they include the Huygens—Fresnel principle, diffraction of light ,Fresnel diffraction and Fraunhofer diffraction etc.

本文首先简要的介绍了衍射光学元件所涉及的波动光学中的几个基本原理和现象：惠更斯—菲涅耳原理、光的衍射、菲涅耳衍射和夫琅禾费衍射等。

In addition, the symmetrical relations and complex zeros of Fresnel integral are studied also. Three-dimensional figure and two-dimension contour lines of Fresnel intergral in the complex plane are given.

此外，本文还研究了菲涅耳积分在复平面上的对称性、零点等性质，给出了菲涅耳积分在复平面上的三维立体图和二维等值线图。

Diffractive efficiency of Fresnel lens is important factor to evaluate the quality of Fresnel lens.

菲涅耳透镜的衍射效率是评价菲涅耳透镜质量的一个重要指标。

With the development of society and demand of energy economy, it is the new direction and development trend that improving the focus and reducing optical losses of Fresnel lens.

随着社会的发展和节能经济的需求，提高菲涅尔透镜的聚焦性，降低透镜的光学损失成为了菲涅尔透镜研究的新动向和发展趋势。

This article through analyzes the Fresnel formula thoroughly earnestly, theoretically development and analysis of the application of Fresnel formula.

本文通过认真透彻地分析菲涅耳公式，从理论上拓展和分析菲涅耳公式的应用。

A river rising in the Auvergne Mountains of south-central France and flowing about 483 km (300 mi) southwest to join the Garonne River north of Bordeaux and form the Gironde estuary.

多尔多涅河：发源于法国中南部奥弗涅山脉流向西南的河流，流程483公里300英里）。在波尔多以北与加龙河会合，形成吉伦特湾河口

Well-known works include the opera "Onegin,""The Queen of Spades", ballet "Swan Lake "," The Nutcracker,"" Sleeping Beauty "and" Fourth Symphony "," Fifth Symphony "," Pathetique (6th) Symphony,"" drop b flat minor Piano Concerto No. 1 ","D Major Violin Concerto on a" symphonic poem "Romeo and Juliet" and other .18-189's visit to Germany, the Czech Republic, France and Britain, and Brahms, Grieg, Dvorak, Gounod, Masi Nie and other famous musicians have formed friendship .1893 year awarded an honorary doctorate in June. In the same year in October in St.

著名的作品有歌剧《奥涅金》、《黑桃皇后》、舞剧《天鹅湖》、《胡桃夹子》、《睡美人》和《第四交响曲》、《第五交响曲》、《悲怆交响曲》、《降b小调第一钢琴协奏曲》、《D大调上提琴协奏曲》、交响诗《罗密欧与朱丽叶》等。18—189年访问德国、捷克、法国和英国，与勃拉姆斯、格里格、德沃夏克、古诺、马斯涅等著名音乐家结下友谊。1893年六月授予名誉博士学位。

The real reason being that they cure their patients without the use of drugs. In 1958, one of those "ill-trained" doctors, Nicholas P. Grimaldi, who had just graduated from the Lincoln Chiropractic College, took the basic science examination of the Connecticut State Board along with 63 medics and osteopaths. He made the highest mark (91.6) ever made by a doctor taking the Connecticut State Board examination.

这其中真正的原因是他们不用药就能把病人治好。1958年，一位这种"缺乏训练"的医生，尼古拉·P·格里麦尔迪与63名医务工作者以及施行骨疗者一起参加了康涅狄格州委员会的基础科学考试，他取得了参加康涅狄格州委员会考试的医生所取得过的最高成绩（91.6分）。

Now, however, all children continue in "comprehensive" schools, and the eleven-plus determines which courses of study the child will follow.

然而现在，所有的孩子都要在综合学校继续学习，所以这次考试只是决定他们将要学习哪些课程。

Cultivatable land , and led to a general recognition that development must not be carried at the cost of agriculture .

城区的迅速扩大在很多情况下侵占了宝贵的可耕地，使人们普遍认识到发展不能以牺牲农业为代价。
