For some EN baths significant precipitation of the metal ions can only occur after thecomplexing agent has been substantially removed by either biological oxidation or chemical oxidation using ozone, potassium manganate, sodium hypochloriteor hydrogen peroxide .

对于一些恩浴金属离子的显着降水后只能出现络合剂已大为拆除或化学或生物氧化利用臭氧氧化，钾锰，次氯酸钠或过氧化氢。

To 6500m a.s.l.. In September 1998, an 80.36m ice core was also recovered in accumulation zone of the East Rongbuk Glacier on the northern slope of Mount Everest. The ice core was dated by seasonal variations of δ〓O (measured by Mat-Plus gas isotopic mass spectrograph with precision of 0.5‰) and major ions (measured by DX-2010 ions chromatography with precision of ng/L), together with the references of β activity peaks. Annual net accumulation was reconstructed based on the dating and density profile of the ice core.

此外，笔者还参加了1998年9月东绒布冰川80.36m冰芯的钻取工作。1999-2000年，在实验室内对上述样品进行了δ〓O测量(在中科院寒区旱区环境与工程研究所冰芯与寒区环境开放研究实验室用Mat-Plus气体稳定同位素质谱仪测量，以δ〓O平均值为-20.05‰的希夏邦马峰地区大气降水作为标准水，测量精度为0.5‰)、主要可溶性阴阳离子浓度的测定(在美国新罕布什尔大学气候变化研究中心进行，测试仪器为DX-2010型离子色谱仪，其测量精度可达ng/L)以及β活化度的测量(在美国新罕布什尔大学气候变化研究中心进行)，并以此为基础尝试重建了该冰芯的年代和净积累量。

We gain the distributing instance as a whole by the spatial analyse of the daily、 mensal and annual precipitation.Then, we adopt mean error、 mean absolute error、 mean relative error、 and the root mean squared interpolation error and the correlative coefficient as the determinant standard of interpolation effect. The results show that the mensal precipitation effect of SIA is the best, and the daily precipitation effect is worse reversely.

然后，对年降水量、月降水量以及日降水量的SIA结果采用平均误差、平均绝对误差、平均相对误差、插值平均误差平方和的平方根误差以及相关系数作为判定插值效果的标准，并得到以下结果：月降水量的SIA效果最好，日降水的相对较差。
