查询词典 curved

The device utilizes a lutetium yttrium orthosilicate scintillator crystal, curved photomultipliers, and Philips' proprietary TruFlight technology , which uses the time difference -- in pico seconds (10-12 seconds)-- between the detection of coincident events to more accurately identify the origin of the annihilation.

飞利浦医疗系统PET/CT产品全球市场总监Jim Cavanaugh介绍说，采用Gemini TF进行全身PET扫描用时不到10分钟，此前进行同样的检查需要15分钟或更长时间，对肥胖病人同样如此；如果医生需要获得敏感性或特异性更高的PET图像，获取图像的时间还是维持在原来的水平上，这需要根据病人临床情况而决定。

Result These difficult root canals caused by broken instruments, luting cement and resinifying agent in canals, root canal calcification and root canal perforation were managed with the success rate of 82.35%, 82.14％, 76.32％and 100.00％ respectively;the incidence of root canal perforation in severe curved root canals was 35.14％during the course of the treatment.

A map projection is any method used in cartography to represent the two-dimensional curved surface of the earth or other body on a plane .

在制图学中，任何将地球的二维曲面表达为平面的方法都可以被称为地图投影。

It's obviously that it's not practical if you use such broken and wrinkled plane mapping. So we must adopt special methods to spread the curved surface, which is called map projection theory.

若用这种具有破裂或褶皱的平面绘制地图，显然是不实用的，所以必须采用特殊的方法将曲面展开，使其成为没有破裂或褶皱的平面，于是就出现了地图投影理论。

In Quantum Gravity theory, gravity is produced by massless gravitons so that gravitons now represent individual packages of curved space that travel through space at the speed of light.

在量子引力论中，引力产生于无质量的引力子，只有这样才能解释引力子何以以独立的空间弯曲因子的形式在空间中以光速传播。
