The authors recommend that body height-thyroid volume index ( HVl) should be used as a marker and 10-year-old children be selected as subjects in IDD monitoring.
建议在IDD监测工作中，应选用身高甲状腺体积指数作为监测指标，选择10岁组儿童作为监测对象。
HVL can describe test bench more abstractly, design plus-and-play and reusable verification modules and provide efficient random and concurrence functions.
这种语言具有更高的逻辑抽象描述层次，实现了模块的即插即用和可重用性，同时提供了强大的随机和并行验证功能。
In this paper, we firstly took a comparative study on the method of the HVL measurement and made a conclusion that we should choose interpolation measurement when the interpolation space selecting is appropriate.
论文首先对比研究了半值层的测量方法，得出当内插间距选取合适时，选取内插法测量最佳的结论。
