目的 比较冠状动脉造影和单光子发射计算机心肌断层灌注显像在诊断冠心病中的敏感性和特异性。

The nuclide chart involves electron, positron, antiproton, antineutron, photon to exhibit the symmetry of mass and charge ideally.

该核素图将电子、正电子、反质子、反中子和光子收录在内，完美地表现了质量和电荷的对称性。

The photonic band gap refers to the crystalline structure of barbules that Jian Zi and his colleagues analyzed using an optical microscope and a scanning electron microscope.

光子带缺口代表鸟的小羽枝的晶体状结构，Jian Zi和他的同事运用了一种光学显微镜和电子扫描显微镜来分析。

This region contains dark matter, baryons and photons.

该区域包含暗物质，重子还有光子。

Without the photo-baryon pressure driving the system outwards, the only remaining force on the baryons is gravitational.

失去了光子-重子的压强向外驱动整个系统，唯一还留在重子上的力就是引力。

On the other hand, the tabular parameters for the treatment planning system to calculate absorbed doses, such as percentage depth dose distribution and cross-profile dose distribution, which are practicable for ordinary field sizes, will be not suitable for small beamlets, especially in inhomogeneity medium.

另外，治疗计划系统使用基于表格的剂量参数(百分深度剂量分布，侧向剂量分布等等)进行剂量计算，这些关系式对大的光子射野是成立的，但却不一定能用于非常小的射野，尤其是在非均匀介质中。

Due to the TomoTherapy machine intrinsic characteristics, some mechanical items, such as the gantry, the couch angle, the collimator etc., do not need to be checked. Additionally, no electron beam verification is needed but the same beam effect can be formed from the different beamlets of the machine.

再者，由於多模式螺旋断层放射治疗仪机器的本质结构特性，有些品质保证测量项目不须实施，如在机械方面不须要做旋转臂、治疗床、准直仪之品质保证测量校正工作，所以在例行的品质保证测量工作上较为简单；此外因多模式螺旋断层放射治疗仪只有单一光子射束(6MV)，而没有电子射束所以在品质保证量测上不须测量电子射束，因而简化许多程序，但电子射束的特性可以由不同的小射束组合来达到相同的效果。

Not if they used their laser blasters and photon torpedoes.

只要他们用激光炮和光子鱼雷不就得啦

So, in the present study, we have investigated the photodissociation of these alkyl bromides at their A-band using resonance-enhanced multiphoton ionization scheme, ion velocity map imaging technique, expecting to get a variety of information.

同时，采用单色双光子质量分辨的零动能光谱技术得到了溴乙烷的高分辨的离子振动光谱，并分析了离子振动光谱与解离中间态的关系。
