Firefighters fashioned a plunger with a heavy climbing rope, a large plywood disk and several canvas bags, fire spokesman Capt. Steve Ruda said.
消防队发言人史蒂夫鲁达上校说,消防队员用一根粗爬山绳,一大块胶合板,和几个帆布包制造了一个简易潜水器。
Rope implementations also often defer evaluation of large substring operations by introducing a substring node.
Rope实现通常也将延迟对大型子串操作的求值,它的作法是引入子串节点。
This saves the time and memory cost of constructing a String from the rope, which, for large ropes, is enormous.
这样就节省了用rope构建String的时间和内存开支,对于大型rope来说,这种开支是相当巨大的。
