Mobile technologies such as EVDO and HSPA provide wide area coverage with consistent bandwidth guaran - tees; while technologies like WiFi provide high band - width and low latency.
诸如EVDO和HSPA这样的移动技术能够利用协调的有保证的带宽提供宽的覆盖范围；而想WIFI这样的技术提供高的带宽和低的等待时间。
Further increasing the substrate temperature broadens the band tail width of the films because the hydrogen content is too low to passivate the dangling bonds at the NC silicon grain surface.
对应更高的衬底温度，因薄膜中的氢不能完全中止纳米晶粒界面的悬键，使薄膜能带带尾加宽。
