说明：  办公人员先根据业务需要，写好合同的文字，但在用户名称、产品名称等变化的位置填写指定的标记字符串，然后通过Delphi把数据库中的实际数据替换掉Word中的文字，最后让Word打印出合同!
(According to the business needs, the office staff first write the contract text, but fill in the designated mark string at the location of user name, product name and other changes, then replace the actual data in the database with the text in word through Delphi, and finally let word print out the contract!)
