根据材料并结合所学知识回答问题。
材料一 实现国家的社会主义工业化的中心环节是发展国家的重工业，以建立国家工业化和国防现代化的基础，因为我国过去重工业的基础极为薄弱，经济上不能独立，国防不能巩固，帝国主义国家都来欺侮我们，本主义国家从发展轻工业开始，一般是花了五十年到一百年的时间才能实现工业化，而苏联采用了社会主义工业化的方针，从重工业建设开始，在十多年中就实现了国家的工业化。——《建国以来重要文献选编》1993年版
材料二 1958年毛 * * 在各地视察期间专门发表讲话自豪地说：到现在，我们还有一些同志不愿意在工业方面搞大规模的群众运动，他们把工业战线上搞群众运动，说成是“不正规”，贬之为“农村作风”“游击习气”，这显然是不对的。——《中国现代化历程》卷三
材料三 在改革开放后的工业过程中，乡镇企业和外资企业可谓是两支突起的“异军”。它们的迅速发展，已成为我国宏观经济的两个新的增长点。——《中国现代化历程》卷三
材料四 坚持以信息化带动工业化，以工业化促进信息化，走出一条科技含量高、经济效益好、资源消耗低、环境污染少、人力资源优势得到充分发挥的新型工业化路子。——江 * * 《在中 * * 党第十六次全国代表大会上的报告》

在算法的4个特性中，算法必须能在执行有限个步骤之后终止指的是算法的______特性。
国家提出要建设一个针对特定灾害的防灾预警系统，以减少灾害损失。共有三个互斥的建设方案，寿命期均为20年。根据统计资料分析及专家论证，如果不建造该预警系统，预期未来每年灾害经济损失为120亿元；如果建造该防灾预警系统，除需要初始投资外，每年还需要支付系统维护费用，但可降低每年预期灾害损失。各方案的初始投资、每年运营维护费用及预期年损失等资料见表5-4。设定基准收益率为8%。
表5-4 各方案投资、费用及预期损失表
| 方案 | 初始投资 | 年运营维护费用 | 预期年损失 |
| 1 | 120 | 12 | 70 |
| 2 | 210 | 20 | 90 |
| 3 | 250 | 30 | 30 |
