透视法

Computerized tomographyof cross-borehole electromagnetic is an advanced technology which successfully uses the principle of CT of medicine in geology. It reflects the physical parameter distribution in scenographic profile according the propagation of electromagnetic waves in lossy media and definite relation between physics and mathematics, finally gives the results by images.

地下井间电磁波法层析技术是一门新技术，它将医学CT的原理成功地运用于地学中，依照电磁波在地下有耗介质中传播规律及一定的物理和数学关系，反演透视剖面上的物理参数的分布，最后以图像的形式表现出来。

The transmission magic-mirror method was applied to visualize and record the whole process of growth and melting of transparent crystals taking place in high temperature up to 1000℃ For matching to three-dimensional observation, a set of special furnace and crucible was designed and the growing process can be observed in two perpendicular directions and recorded in situ by CCD camera simultaneously.

最近开发了三维光学实时观察法，应用透视魔镜法实时观察并记录透明晶体的生长和溶解过程，最高使用温度为1000℃配合三维观察，设计并制造了一套独特的生长炉和坩埚，有二组互相垂直的光路可同时实时观察晶体生长过程，并通过CCD摄像头进行同步记录。

Methods Twenty-seven patients suffering from mallet finger accompanied by avulsional fracture were treated with Ishiguro method or its modified method. During the operation, a blocking pin was inserted percutaneously with DIP flexed, then the DIP was fixed at a position of full extension with another Kirschner wire. When the fracture fragment was big with rotation displacement, a third Kirschner wire could be used to correct the displacement and fix fracture. Results The patients were followed up 2 months to 6 years and 6 months with an average of 9.3 months postoperatively.

采用石黑法及其改良法治疗27例伴撕脱骨折的锤状指，在透视下运用闭合穿针的方法，在远侧指间关节屈曲位时于背侧插入阻挡针，然后用另一根克氏针将DIP固定于充分伸直位；当较大的骨折块向背侧有旋转移位时，可加用一根克氏针撬拨复位并固定骨折块。

We propose novel methods for both techniques to monitor the surrounding area of a vehicle. For fisheye camera calibration, we proposed a novel photogrammetric calibration method using planar calibration objects together with a distortion model based on the design of the fisheye lens. By minimizing the residual error between observed and predicted image coordinates of feature points, a set of camera parameters that best describe the imaging process of the camera can be obtained.

在鱼眼摄影机校正中，我们提出基於摄影校正法的创新的校正方法，其中利用平面校正物进行鱼眼摄影校正，并以视野失真模型(field-of-view distortion model)作为鱼眼失真模型，透过降低摄影机校正误差进行非线性的摄影机参数最佳化，由已校正的鱼眼摄影机所拍摄的影像皆可经由失真校正将鱼眼影像还原至透视投影影像。

In this context, the research and instruction of mathematics—which, as established by Christophorus Clavius, teacher of Matteo Ricci, included geography and cartography—constituted a process of spiritual elevation, a journey toward salvation.

在耶稣会士于1551年建立的罗马学院中，来自整个欧洲的学生除了学习神学以外，还接受着高强度的学术培训，学习修辞学、记忆法、哲学，以及数学，包括算术、几何、透视、宇宙学、地球体学、天文制表、天体观测学（后四者可称作 sphaera ），还要学习计时学、音乐、力学、水文地理学和建筑学。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
