数字孪生水利建设提出的“四预”，具体是什么？相互之间什么关系？

----2021年4月，水利部部长李国英明确阐释了智慧水利建设中数字孪生流域的定位和作用，提出了智慧水利业务的“四预”功能，并对任务分工和保障措施提出了具体要求。
----2021年6月28日，水利部党组召开“三对标、一规划”专项行动总结大会提出，要推进智慧水利建设，按照“需求牵引、应用至上、数字赋能、提升能力”要求，以数字化、网络化、智能化为主线，构建数字孪生流域，开展智慧化模拟，支撑精准化决策，全面推进算据、算法、算力建设，加快构建具有预报、预警、预演、预案（“四预”）功能的智慧水利体系　　

----“四预”之间的关系

　　“四预”之间环环相扣、层层递进，是数字孪生流域的出发点和落脚点。

　　“预报”是基础，对各类水安全要素进行预测预报，为预警工作赢得先机。

　　“预警”是前哨，对各类危害及次生灾害的预警信息指导水利工作一线，为启动预演提供指引。

　　“预演”是关键，在数字孪生流域中对典型历史事件场景下的水利工程调度进行精准复演，确保所构建的模型系统准确，对设计、规划或未来预报场景下的水利工程运用进行模拟仿真，及时发现问题，科学制定和优化调度方案。

　　“预案”是目标，确定工程调度运用、非工程措施和组织实施方式，确保预案的可操作性。

    myostatin, a pure regulator of muscle progress. Developed by Acceleron Pharma, it was originally studied
    as a treatment for muscle-wasting circumstances like muscular dystrophy.

    making it interesting to athletes and bodybuilders seeking elevated muscle mass
    and power. When you go to just any GYM and take a close have a glance at the members
    understanding, then come again a yr later,
    you’ll discover that the majority of them nonetheless use the
    identical weights as throughout your first visit.
    Steroids can significantly improve muscle development, power, and
    recovery. However, to maximise these benefits, a tailor-made workout plan is essential.
    The increased protein synthesis, nitrogen retention, and
    enhanced endurance offered by steroids allow for more intense and frequent training periods.
