It is possible to have zero-sized memory blocks (i.e. blocks consisting solely of an MCB header). The ALLOC function does not refuse to allocate zero-sized blocks. In addition, zero-sized blocks may be inevitably created in the course of calling other functions. For example, if an existing allocation is resized to be exactly one paragraph smaller, DOS will be forced to create precisely such a zero-sized MCB.

中国掌控全球约82%的钨矿产量，作为全球最大的钨资源国和供应国，对钨矿实行严格的开采总量控制，2025年钨矿开采总量为6.7万吨，从源头限制了供给的弹性。国金证券在研报中指出，2025年中国钨精矿开采总量控制第一批指标同比缩减6.5%，叠加环保及安全督查严格限制表外钨矿山产出，有效供给持续收缩。
