【美国《核武器数据汇编》1985年5月报道】美国核武器发射和贮存的安全措施如下: 1.部署到欧洲的所有核武器都有至少6位数字的密码锁,密码锁分早期型、PAL-D型和PAL-F型; 2. 所有的核武器都按“点”安全设计,即如果一部分高能炸药发生爆炸,也不会产生核链式反应而导致核爆炸; [United States Nuclear Weapon Data Collection, May 1985] Security measures for the launching and storage of nuclear weapons in the United States are as follows: 1. All nuclear weapons deployed to Europe have at least 6-digit code locks of the early type and PAL-D Type and PAL-F type; 2. All nuclear weapons are “point” safe design, that is, if part of the high explosive explosions, it will not produce nuclear chain reaction and lead to nuclear explosions;
