求翻译！！！！！！！！！！！！！！！！

The roller compacted concrete method used in dam construction has increased the interest of using stepped channels and spill-ways. A larger reduction of the downstream stilling basin due to the reduction in specific residual energy is attained for stepped spillways than for smooth spillways, reaching up to six times that of conventional spillways (Sorensen 1985, Christodoulou 1993).
若是软件翻译就不劳烦大家了。下边还有一段：Numerous studies concerned with stepped spillways were
presented such as those by Peyras et al.(1992), Chamani and
Rajaratnam (1999a), Valentin et al. (2004), and Chinnarasri and
Wongwises (2006). Figure 1(a,b) shows the flow characteristics
over stepped spillways, classified as nappe flow for small dis-charges (Fig. 1a), transitional flow for moderate discharges, and
skimming flow for large discharges (Fig. 1b). For the latter, water
skims as a coherent stream over the pseudo-bottom formed by
the step edges (Rajaratnam 1990, Ohtsu and Yasuda 1997, Matos
2001, Chansonet al.2002). The skimming flow is predominant
as most prototype spillways operate at large discharges. It is char-acterized by significant losses and momentum transfer from the
main stream to the recirculation zones. Transition to a skimming flow is recognized visually or by video and image processing
(Sánchez-Juny and Dolz 2005).

Answer 1

在水坝的建设中用滚筒机碾压的具体得方法已经增加了使用渠道泄洪的收益。一个下游的盆地的储水量的更大的减少是由于其它的剩余的能量的减少达到渠道泄洪而不是自然的（指没有通过渠道的）泄洪的目的，达到六次传统的泄洪量
望采纳!

Answer 2

碾压混凝土的方法用于大坝建设增加了利息的使用加强渠道和泄漏的方法。一个更大的减少下游消力池由于减少特定的残余能量是获得对加强
无数的研究关注了各项措施如溢洪道由Peyras et al。(1992),Chamani andRajaratnam(1999 a),瓦伦汀et al。(2004),Chinnarasri andWongwises(2006)。图1(a,b)显示了流characteristicsover泄漏了
