The BOLD response typically peaks ~4–6 seconds after neural firing and returns to baseline after ~10–12 seconds. This means that the fMRI signal at time t reflects neural activity from several seconds earlier, i.e.: from the stimulus presented several seconds earlier. The image shows the canonical hemodynamic response function (HRF) presented in neuroscience literature and implemented in many frameworks. In practice, the exact shape and timing vary across voxels depending on vascularization and other physiological factors.

农历马年的第一缕阳光洒在哈法亚油田，哈法亚公司工程部副经理陈文昱像往常一样，一早来到CPF3采出水处理厂查看运行情况。这一去年刚刚投产的厂区将油田采出水处理能力从过去的5万桶/天提升至20万桶/天，在助力提升原油产能的同时，也为生产污水循环利用提供了技术保障。
