中文摘要：

利用单因素分析方法，计算三效塔式太阳能海水淡化系统各个参数对太阳能海水淡化系统淡水生产成本的单因素影响值，分别给出太阳能集热系统成本、储热水箱成本、海水淡化装置成本、装置运行年消耗动力费用、设备使用年限和淡水年生产总量等参数对淡水生产成本影响的程度，明确降低淡水生产成本的方向，有助于太阳能海水淡化装置的深入研究。

英文摘要：

Based on the calculation of the single-factor impact values of the parameters of a triple stage tower-type of solar desalination unit by utilizing a single-factor analyzing method, the influences of the cost of solar heating system, the cost of hot water tank, the costs of desalination unit and yearly electrical power, the life time of solar desalination unit and the yearly yield of fresh water, on the cost of the fresh water production of the solar desalination unit are studied. It is helpful to do the further investigation on solar desalination systems for reducing the cost of fresh water production.
