All the flow control variables (commonly Boolean flags) are stored as plain primitive types. As a high level rule I always say.

所有的流程控制变量(通常是布尔标识)都会以普通的基本变量类型来保存。

By using of the 5-level primitive equation model, the short range evolution of the subtropical ridge and the subtropical high structure for 23-26 June 1980 was experimented.

本文利用5层原始方程模式对1980年6月23—26日梅雨期暴雨期间副高位置的短期演变、副高结构的短期变化作了一次数值预报试验。

As they did so, brain activity shifted from the striatum, a more primitive brain region, to the prefrontal cortex, which is responsible for high-level functions such as planning and decision making.

他们这样做，从纹状体，一个更原始的大脑区域，大脑活动转移到前额叶皮层，这是高层次的功能，如规划和决策负责。

In a high-level language, square root might simply be a primitive that you can use rather than you having to go over and code it.

一个高级的语言，平方根可能仅仅,只是你能使用的一个基本要素,而不是你需要去编译它。
