气孔簇
1.
However, some plants restricted in several genera of vascular plants have stomatal clusters in which more than one stoma is adjacently arranged with no epidermal cells among them.
而在有限分布的几个科属的植物种中发现气孔成簇分布的现象 ,即由 2至多个紧密相邻的气孔器组成相对独立的单元 ,称为气孔簇 (stomatalcluster)。

Assuming a KASCADE-like hadron calorimeter is set up at the center of the Yangbajing ARGO array,selecting events with air shower(AS)cores hitting the calorimeter,using the full-coverage ARGO array as AS anti-coincidence and using the calorimeter to measure energies of the unaccompanied hadrons,the directly arrived primary p.
假定将一台类似于KASCADE的强子量能器设置在西藏羊八井ARGO探测器的中央,选择大气簇射(AS)轴心落在强子量能器内的事例,用全覆盖ARGO阵列作AS的反符合,用强子量能器测量非伴随的高能强子,即能以已知的效率得到一个直达质子事例样本。

The time-space structure of particles for individual air showers induced by primary γ-rays and protons at the observation level is analysed by Monte Carlo simulation.
利用Monte Carlo模拟程序模拟甚高能区原初γ射线和质子大气簇射过程,分析γ射线和质子簇射在观测平面上的时空结构,利用大气簇射次级粒子到达时间涨落和空间横向分布特征,进行原初γ射线成分和质子成分的有效分辨,为中意合作羊八井ARGO实验进行γ点源的寻找提供了降低强子本底的方法,该工作还估计了该分辨方法对γ信号显著性的影响。
6) air shower

1.
It is shown that measuring the high energy hadrons in air shower cores at high altitudes(like Yangbajing) can provide some new observables which are sensitive to the cosmic ray composition at the knee region.
预期在高海拔测量宇宙线空气簇射(AS)轴心中的高能强子成分能提供对宇宙线膝区成分灵敏的一些新的AS观测量。
