[简答题]

某市博览中心的机电工程由某安装公司总承包，合同约定，安装公司负责设备采购、施工和试运行验收，工期为2个月，合同价为固定总价。机电工程中的一些主要设备由业主指定供货商，其中空调工程的冷水机组等设备，业主指定了某国厂商的产品。安装公司及时向厂商进行了产品询价，得知设备从订货、运输到施工现场最少需要6个月。安装公司依据冷水机组的型号、规格、数量、技术标准、到货地点、质量保证、运输手段、结算方式和产品价格与厂商签订了设备供货合同。
工程施工到6个月后，因该国的政局不稳定，冷水机组等设备延期60天到达我国口岸，所以冷水机组等设备在通关时，未经商检就直接运到施工现场。安装公司组织本公司人员对设备进再了开箱验收。因设备晚到60天，安装公司调整了施工进度计划，增加施工人员和机械设备，加班加点，冷水机组等设备按原计划安装到位，通电试运行并验收合格。由于安装公司因赶工期增加了费用支出，向业主提出费用索赔，被业主拒绝。

针对背景中的风险，安装公司在订立设备采购合同时应采取什么对策？

[单项选择]When Dr. John W. Gofman, professor of medical physics at the University of California and a leading nuclear critic, speaks of "ecocide" in his adversary view of nuclear technology, he means the following.

Rather than being biodegradable, plutonium destroys biological properties.
