irradiation和radiation有什么区别
区别是:
前者是辐射的过程,后者是辐射(射线)这种物质本身。

2、Early lesions can be successfully treated with irradiation or cautery and curettage.

radiation 和irradiation有何异同
radiation
n.
放射,辐射; 发射; 发光
放射物; 辐射线[能]
散射器
【生】辐射形;【测】射出测量法;【医】射线疗法
语义扩展; 语义推演
irradiation
n.
放射,照射
阐明,启发; 启迪
【物】光渗; 光线; 辐照[射]
【医】照射
扩散
这样看不出来什么区别吧?
其实通俗一点讲 虽然两词都有照射的意思 但是radiation是 "主动"的发出照射的一方,而irradiation强调 "被动"被照射的物体,那个被照射的也可以说是 have been irradiated.
Radiation is emitted from something and travels from its point of origin to somewhere else.
When radiation hits something else (and is therefore stopped) the thing that has been hit is said to have been irradiated.
举个例子
A sunbather is undergoing irradiation by radiation emitted by the sun.

convection和conduction什么区别?
从热传递方面来说conduction是传导,也就是指固体中热传递的一种主要方式,在不流动的液体或气体层中传递,在流动情况下往往与对流一起发生,例如,你说的两个固体相互接触时,热量从高温的物体传向低温的物体。
convection指热量通过流动介质,由空间的一处传播到另一处的现象。都有流体参与。
conduction指单向的情况比较多,convection双向情况较多。
