Object must be named uniquely , the one that is specified in the web . config file uses a name other than the default but is also set as the default provider so that it will be used instead of the 对象中的所有提供程序都必须唯一地命名， web . config文件中指定的提供程序使用了与默认提供程序不同的名称，但是也被设置为默认提供程序，以便将使用它而不是使用默认asp . net配置中指定的
High accuracy for the time measuring is required in modern scientific experiment , scanning speeds on the image plane is a reference for the time measurements in high speed rotating mirror camera , and , it changes as the rotating velocity only 现代科学实验对时间信息的测量提出了极为严格的要求,对于高速转镜相机而言,其像面上的扫描速度是时间测量的基准,扫描速度值唯一地随转镜速度而变。
That is the following in essence . a sufficient mass of cold matter will necessarily collapse to a black hole , and stars with different mass will evolve into the white - dwarf - star , the neutron - star or the black - hole eventually because of the radiation of the burning core . the collapse of stars with sufficient mass leads to a black hole endowed with mass and charge and angular momentum , no other adjustable parameters : " a black hole has no hair . 第二章简单介绍一下“黑洞无毛”理论形成，即足够质量的冷物质能够塌缩成黑洞，不同质量的恒星由于核燃烧辐射最终会演化成为白矮星、中子星或黑洞，以及黑洞的终态系统唯一地由质量、电荷和角动量确定，而无其它物理参数，此即为“黑洞无毛”理论。
By computing the between two resolution units , we can estimate terrain azimuthal slopes and derive estimate of terrain elevation . the terrain contour is determined uniquely by ay / from azimuth slop on range gates . american began to study p - sar three - dimensional images technology in 1990s Schuler已经证明，对于一个均匀分布场景， sar图像上两个相邻分辨单元的极化椭圆方向角偏移量，与地形方位向坡度的对应关系是线性唯一的，地形方位向的倾斜度可以通过解唯一地被测定。
We systemically discuss how to uniquely decide an infinite plane homography matrix by using the structure information in scene and how to evaluate a homography matrix which convert affine reconstruction to euclidean reconstruction by solving absolute conic images . we give three constraints of absolute conic images and use these constraints to evaluate absolute conic images and then to rec 系统地讨论了如何利用场景中的结构信息，来唯一地确定无穷远平面的单应矩阵，进而由射影重构恢复仿射重构，以及如何通过绝对二次曲线的像求解将仿射重构变换为欧氏重构的单应矩阵。
