  1. 3 for example, if ambient gamma radiation is the only factor contributing to the radiation dose to a person, this dose of 5000 microsieverts may be reached when the ambient gamma dose rate is 1000 microsieverts per hour more than 3000 times above background and lasts for 5 hours ; or when the dose rate is 200 microsieverts per hour more than 600 times above background and lasts for 25 hours

    3 .例如，假若環境伽瑪劑量率持續高達每小時1000微希沃特超過本底值3000倍，則在5小時內，因為環境伽瑪輻射所引致的總劑量便可能達到上述的5000微希沃特。若環境伽瑪劑量率每小時200微希沃特超過本底值600倍，則個人須持續受此輻射影響25小時，所受的總劑量方可達到上述5000微希沃特。
  2. A patch antenna with air holes in the substrate has been designed. the finite - difference time - domain ( fdtd ) method together with the perfectly matched layer ( pml ) boundary treatment has been used to study the performance of the antenna. it is shown that the surface waves are significiently suppressed, the frequency bandwidth is improved, the sidelobe levels are reduced and consequently the gain in the forward direction is improved by 14 db ( about 4 db higher than the value reported previously )
