2.The antielectron, or positron, was discovered in 1932.

反或正,是在1932年被发现。

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

该核素图将、正、反质、反中和光收录在内，完美地表现质量和荷的对称性。

4.The key of this technology depended on increasing batteries positron electrode -- zincous -- the electron that can carry.

这项技术的重点在于增池正极——阳极——所能携带的。

5.When two such gamma-ray beams collide, the interactions are even cleaner than electron-positron or muon-antimuon collisions.

当这样的两束伽玛射线碰撞时，其交互作用比「╱正」或「缈╱反缈」的碰撞更乾净。

6.Objective To evaluate the value of 18 F-deoxyglucose (FDG) positron emission tomography (PET) in detecting the primary focus of metastatic cancer with an unknown primary.

目的探讨18F-脱氧葡萄糖(FDG)正发射型体层摄影术(PET)全身显像在原发灶不明转移癌中的作用。

7.Objective To evaluate 18 F deoxyglucose positron emission tomography (FDG PET) in the detection of suspicious recurrence in head and neck cancers , as compared with CT/MRI imaging.

目的探讨18F脱氧葡萄糖(FDG)正发射型体层摄影术(PET)在头颈部癌瘤复发的临床价值。
