CM company, the biggest telecom company, must face to the challenges coming from all aspects, especially from CU company who owes CDMA. It is just CDMA that leads to CM company's main profit headspring-VIP customers losing.
作为从中国电信剥离出来的优良资产中国CM公司，遇到了来自各方面的挑战，尤其是受到CU公司的CDMA的冲击，使其主要利润源&大客户的流失率不断上升。
Stoichiometric CIS film can be synthesized with a homogeneous element distribution and a single chalcopyrite phase from the Cu-In precursor film with a Cu/ In atomic ratio of 1. The CIS film exhibits p-type conduction and has a resistivity reaching 1.2 k Ω· cm.
在总体Cu/In原子数比接近1时，硒化后可得到各元素分布均匀、具有化学计量比的CIS，且晶体结构为单一的黄铜矿相。CIS薄膜的导电类型为P型，电阻率达到1.2kΩ。
The heavy metals concentrate on the upper horizons, especially the 0~ 20 cm horizon in the soil profile, and decrease abruptly below the depth of 20 cm. The contents of soil heavy metals in the spring are higher than those in the autumn.
土壤重金属集中于土壤表层，Cd、Cu、Pb、Zn主要富集在0￣20cm土层中，20cm以下深度的含量大大减小，土壤重金属元素含量春季高于秋季。
