Boost Unordered Translation (zh_Hans) - Chinese (Simplified Han script) @ Boost-Weblate

English

In a multithreaded scenario, the iterator `it` may be invalid at point B if some other thread issues an `m.erase(k)` operation between A and B. There are designs that can remedy this by making iterators lock the element they point to, but this approach lends itself to high contention and can easily produce deadlocks in a program. `operator[]` has similar concurrency issues, and is not provided by `boost::concurrent_flat_map`/`boost::concurrent_node_map` either. Instead, element access is done through so-called _visitation functions_:

	English Even if your supplied hash function does not conform to the uniform behavior required by open addressing, chances are that the performance of Boost.Unordered containers will be acceptable, because the library executes an internal __post-mixing__ step that improves the statistical properties of the calculated hash values. This comes with an extra computational cost; if you'd like to opt out of post-mixing, annotate your hash function as follows:
	Chinese (Simplified Han script) 即使提供的哈希函数不符合开放寻址所需的均匀分布特性，Boost.Unordered容器的性能通常仍可接受，这是因为库会执行内部__后混合处理__步骤来改善计算哈希值的统计特性。当然这会带来额外的计算开销；若希望禁用后混合处理功能，请按以下方式对哈希函数进行注解： 131/4480 · 448 Needs editing

	Chinese (Simplified Han script) 多线程场景中，若其他线程在 A 和 B 之间执行 `m.erase(k)` 操作，迭代器 `it` 可能在 B 点失效。虽然存在通过锁定指向元素来修复此问题的设计方案，但这种方法容易引发高竞争并可能导致程序死锁。 `operator++[]++` 也存在类似并发问题，因此 `boost::concurrent++_++flat++_++map` / `boost::concurrent++_++node++_++map` 也未提供该操作。替代方案是通过__访问函数__操作元素： 241/5390 · 539 Needs editing
