Compared with before radiation,there was insignificant difference in the thyroid function after radiation in those whose partial thyroids were in the field of irradiation.

放疗仅波及部分甲状腺者，放疗后甲状腺功能无明显改变。

Their thyroid functions (including TT3,TT4,rT3,TSH)were determined in a prospective study. Results After radiation TT3,TT4,rT3 were lower than before in those whose whole thyroids were in the field of irradiation(F=4.92-5.23,q=4.81-5.12,P.05). Three patients developed clinically and cheminically hypothyroidism in 2 years after radiation.

结果放疗波及全部甲状腺者放疗后血清总T3 (TT3 )、总T4(TT4)、反T3(rT3)值较放疗前下降，差异有显著性(F=4.92～5.23，q=4.81～5.12，P.05)，且2年内有3例发生甲状腺功能减退(其中1例为一过性)。

The sensitivity of moso-scale model to radiation is studied by including and omitting the variation of atmospheric temperature caused by radiation in the meso-scale regional climate model RIEMS.

在中尺度区域气候模式RIEMS中通过考虑和不考虑辐射对大气温度变化的影响来研究中尺度气象过程对辐射的敏感性。

A greenhouse gas allows most visible solar radiation to pass through, but it absorbs and reradiates outgoing infrared radiation, thereby warming the surface.

温室气体容许太阳辐射中的多数可见光穿透，但会吸收地球所散发的红外光，并将其再辐射，因而暖化地表。

In the above all-sky map from the COBE satellite, radiation in the Earth's direction of motion appears blueshifted and hence hotter, while radiation on the opposite side of the sky is redshifted and colder.

在COBE卫星的全天微波背景辐射图上，向地球发来的背景辐射表现出蓝移，而背向地球而去的背景辐射表现为红移。

The log10 of survivors from radiation is plotted against the radiationdosage, and the radiation D or D10, which is comparable with thethermal D value, is obtained. The D10 is defined as the amount ofradiation in rads (ergs of energy per 100g of material) requiredreducing the microbial population by 1 log (90%).

若将照射中存活微生物数目的log10值对照射剂量进行标绘，则可求出辐照D值(即D10值)，此值与热力D值相当。D10值的意义是微生物总数减少一个对数周期(90％)所必需的照射拉德数(每100克物质得到的能量尔格数)。

Some techniques which are used for the measurement of grinding temperatures,such as infrared radiation pyrometers,optical fiber infrared radiation pyrometer, two-color infrared system and infrared imaging system,are summarized,compared and discussed.

磨削过程中，大量无规则离散分布在砂轮表面的磨粒对工件划擦、耕犁和切削综合作用，其所产生的热体现为工件的温升、砂轮与工件接触面的温升、工件已磨削表层的温升、磨粒切削刃温度和切屑温度。
