diffuse source meaning in English

扩散源

Gis - based dynamic risk assessment for groundwater nitrate pollution from agricultural diffuse sources
的农业面源硝酸盐地下水污染动态风险评价
It is especially useful for measuring measure weak , scattering and diffuse sources with the highest possible sensitivity
该系统因为具备极高的可能灵敏性，故特别适合测量难以测量的、散射的发散源。
Mms - based instruments are ideal for measuring weak , scattering and diffuse sources and samples because the spectrometer can collect and process far more light through its wide area aperture , without affecting spectral resolution
基于mms技术的设备非常适合测量测量难以测量的、散射的发散源以及样品，因为通过一个大口径编码光阑，这种光谱仪就能够集聚并处理更多的光线，而不会影响光谱分辨率。
These disks are used to create a diffuse source that is optimal for coupling into fibers and attenuating the overall signal when spectrometer saturation is an issue and other attenuation methods ( such as adjusting spectrometer integration times ) are impractical or undesirable
当分光计的饱和度成为问题或其它衰减方法（如调整分光计综合时间）不合实际或不合要求时，这些盘用做散射源，则对与光纤耦合和衰减所有信号最优。
