如果多个箭头显示一个环形的锁请求模式—由于它们正在相互等候其它线程释放锁，所以线程彼此阻止运行—结果就形成了一个死锁。
If multiple arrows show a circular lock-request pattern — threads prevent each other from running because they are waiting for each other to release a lock — then you have a deadlock.
在经过好几年的刻苦研究和讨论以后，NASA的科学家已经将他们一开始的50多个登陆点削减到了4个，它们分别是：埃伯斯·沃德环形山、霍尔登环形山、马沃斯山谷以及盖尔环形山。
After several years of painstaking research and debate, NASA scientists whittled down their initial list of over 50 sites to four - Eberswalde Crater, Holden Crater, Mawrth Vallis, and Gale Crater.
