The uses of this adaptable material have been broadened dramatically by new technologies : glass fibre optics ? more than eight million miles ? carrying telephone and television signals across nations, glass ceramics serving as the nose cones of missiles and as crowns for teeth ; tiny glass beads taking radiation doses inside the body to specific organs, even a new type of glass fashioned of nuclear waste in order to dispose of that unwanted material
這種適應性強的原料的使用通過新技術顯著地被擴大了:玻璃光學纖維-長於八百萬英里-承載著電話和電視信號越過國家,玻璃陶瓷製品應用於飛船前端椎體和牙冠;帶放射線的小玻璃珠在身體內有特殊的功效,甚至一種新的玻璃類型是核廢料式,為了除去不必要的原料。This article according to the acquirement of the system parameters such as : temperature sensitivity 、 angle resolution 、 image forming time etc to design the type and diameter of the antenna ; the receiver type, integral time, rf gain, lpf gain ; the mode of calibration ; the sample frequency and program of the daq ; the scanning time, scan type, etc
本文根據系統溫度靈敏度、角解析度、成像時間等參數要求,對系統天線類型、直徑,接收機類型、積分時間、射頻增益、視頻放大器增益,定標方式,數據採集卡的采樣頻率、編程及驅動裝置的掃描速度、掃描類型等進行了詳細的分析設計。Based on the previous theory, the fdtd method is used to analyze practical antennas, which include dipole antenna, microstrip antenna, log - periodic antenna and broadband resistance loaded monopoles. the particular problems that occur in the calculating of vary type antennas are discussed. the cross - section field of microstrip line and two - conductor line are analyzed, and the effect on the numerical result arising from the incident cross - section mesh size is discussed
在前面理論的基礎上,將fdtd用於振子天線、微帶天線、對數周期天線、電阻加載振子天線等各種天線的計算中,對各種不同類型天線計算中所遇到的特殊問題進行了詳細的討論,並分析各種開放場傳輸線如微帶線、平行雙線等橫向場分佈,討論了入射網格橫向截斷區域的大小對計算結果的影響。Secondly, some techniques for image segmentation, such as edge - detection, grayscale thresholding and texture, are represented in detail. in the third part, two primary ways are designed for 3d modeling, one is based on the contours triangularization while the other is based on the iso - surfaces extraction. we use a condensed history monte carlo method to calculate and build up the radiation dosimetry, which is a regular data set suitable for creating the iso - surfaces
論文首先介紹了醫學影像的獲取和預處理的方法,包括dicom標準、醫學影像的圖像增強及圖像校正等內容;提出了基於邊緣提取、灰度閥值和紋理信息等原理的器官分割方法;為了建立三維人體模型,介紹了兩類方法;基於輪廓線的方法和基於等值面提取的方法;在建立放射劑量場時,使用了經典的montecarlo方法;最後,詳細介紹了傳統的等值面提取方法( marchingcubes ) ,並提出了一種啟發式搜索的marchingcubes方法。Which will eventually form stars of spectral types g, k or m. t tauri stars are surrounded by a huge cloud and they are very young, with low surface temperature. they emit most of their light in the infrared region and they appear red. a general principle is, a violent reaction will give out short wavelength waves, like gamma rays or x - rays ; while a gentle process will radiate long wavelength waves, like radio or infrared
,這類星最後會演化為g k或m型恆星,金牛座t型星為表面溫度低而非常年青的恆星,四周被星雲所圍繞,所以這種星顏色偏紅,較容易在紅外線波段找到一個普遍的原則是,如果活動越激烈,則所放出的光波波長越短,主要會為伽瑪或x射線如果活動溫和,則會發放出如無線電波或紅外線等長波長電磁波。分享友人
