Why dose a whole field with chemicals if you can spray only where they are needed?

如果你可以只在需要的地方喷洒化学药品，为什么要在整个田地里喷洒呢？

The decrease of the gate oxide, the differences of field oxides processing and the selection of the substrate materials will all affect the total dose radiation effects of MOS devices.

器件栅氧厚度的减小、场氧工艺的改变以及衬底材料的不同等都将导致MOS器件的总剂量辐射效应发生改变。

The results showed that the dose distribution in the irradiation field was uniform. The demands of scientific research and radiation processing were met satisfactorily.

结果表明，辐射场的剂量分布比较均匀，可以满足科研和辐照加工的需要。

They also calculated impact dose injury risk parameters common to laboratory and on-field traumatic neuromechanics: linear acceleration, angular acceleration, angular velocity, Gadd Severity Index, diffuse axonal injury, acute subdural hematoma, and brain contusion.
