博物馆在储存文艺复兴时期的油画时，要遵循严格控制周围温度和湿度的标准，把变化限制在狭小的范围内。
When storing Renaissance oil paintings, museums conform to standards that call for careful control of the surrounding temperature and humidity, with variations confined within narrow margins.
温度变化得很慢，而且被控制在相对严格的范围内。
Changes in temperature occur slowly and are constrained within relatively tight bounds.
所以在你的控制范围之内唯一可以变化的是你能决定什么该放进去或者拿出来——也就是你会选择什么样的任务。
So the only variable in your control is what you decide to put in or take out--what tasks will you choose.
