And unfortunately, many people who have RLS also have trouble controlling sudden limb movements, which can occur every 20 to 30 seconds all night long — a major sleep disrupter.

并且不幸的是，许多RLS患者同时有控制腿部突然抽动的障碍，这种抽动在整个夜间每隔20至30秒就会发生一次。

The condition was first described in 1945 by Swedish nerve specialist Karl-Axel Ekbom. As a result, RLS is sometimes known as Ekbom syndrome.

瑞典神经病学专家卡尔 - 阿克塞尔·埃克波姆在1945年首次发现这种疾病，因此不宁腿综合征又被称为埃克波姆综合征（Ekbom syndrome）。

Finally, a numerical example shows that the modified RLS algorithm result in faster convergence speed by solving the contradiction between speed and accuracy.

算例表明：改进的RLS算法能解决收敛速度与收敛精度之间的矛盾，有效地加快了收敛速度。
