It is easy to write overly complex and error prone threaded code or code that only uses one core on a24 core box yet is still CPU bound .

编程人员很容易编写出过于复杂且容易出错的 线程 化代码；也很容易编写出只使用24核系统上的一个 内核的代码，无法充分利用整个CPU。

The primary structure of the plastic part was modified . And the cavity was designed to be in the moving half the threaded core and the gear transmission system in the fixed half . So that the injection mould structure is simple and it can demould automatically .

分析了化妆品瓶盖的螺纹结构，修改了原塑件结构，型腔设计在动模， 螺纹型 芯、齿轮传动机构设计在定模，使该注射模结构简单，并可自动脱模。
