In external studies of mechanism may be a feasible approach to explore biological effects of rf radiation in the case of no persuadable conclusion of epidemiological and in external studies 因此，尽早明确射频场的作用机制从而确定流行病学和实验研究的生物指标，是揭示移动电话射频辐射生物学效应的必要途径。

At the same time , the system is a poor information system with gr ay attribute , and it can be comparatively analyzed with gray relational assessment , which can make the assessment results more reliable and persuadable 同时，该系统是一个贫信息系统，具有灰色性质，我们用灰色系统理论中的灰色关联度分析方法对系统进行比较分析，使评价结果更具有可靠性和说服力。

On one hand , is the product of beam waist radius and half divergence angle , wavelength is not involved . so there is possibility to compare the acutal focusing ability among laser beams with different wavelength . on the other hand , is a calculated result by measuring experiment , and it is more brief and persuadable than m 2factor , since the latter one is a ratio with basic mode gauss beam 论文研究论证了用值评价激光光束质量的实际意义在于两个方面,一方面它仅仅包含了光束束宽和发散角,不涉及波长的因素,使不同波长激光束的可加工能力具有可比性;另一方面,值是根据对光束传输路径上不同位置处束宽实际测量结果的计算值,比其在与基模高斯光束进行比值计算得到的m2因子更简洁、更有说服力。
