提出并以ＺｎＯ为例初步考察了用于金属氧化物的簇模型选取的配位数原则，即尽可能选取边界悬空键总数最少的簇模型，使簇模型“边界效应”尽可能低．在此基础上研究了ＣＯ在一系列按配位数原则选取的（ＺｎＯ）ｎ表面簇模型上的吸附行为．结果表明，配位数原则有效地缩小了簇模型的选取范围；依配位数原则确立的ＺｎＯ表面簇模型，能够对ＣＯ／ＺｎＯ吸附体系给出合理的定性解释．计算还表明，考虑相关效应有助于进一步改善计算结果．

Dear Editor,Tumor-associated macrophages(TAMs)are critical pro-tumor immunocytes and depletion of TAMs has been exploited for cancer therapy.1 However,the phenotypes and functions of TAMs are plastic,TAMs can also be effector cells by engulfing tumor cells and recruiting cytotoxic T cells,thus shaping the actions of TAMs is more scientific rational than depleting them indiscriminately.2 To promote the entry of reorienting TAMs into the clinical treatments of tumors,it is essential to explore the underline mechanisms controlling the anti-and pro-tumor activities of TAMs.
