题目:

关于百慕大三角区之谜目前猜想是水合天然气引起的,在海底,由于温度低、压力大,动植物遗体腐烂变成的天然气与水结合,形成了固态的水合天然气。当这些水合天然气稳定的条件一旦受破坏,它们就可分解出气态天然气,以气泡上升。上升的气泡流导致海底压力变小,更多的固态水合天然气汽化,这样导致大量天然气溢出洋面。大量天然气气泡使海水密度变小,浮力下降,当船舶驶入这个区域时。海水浮力支撑不住船舶重力,而使船舰沉入洋底。飞机飞入这个地带,则可引燃天然气,而被烧毁坠入海中。

(1)把动植物遗体变成天然气的生物是生态系统中的什么成分?

(2)潜艇舱内各空气过滤口放了盛有Na2O2颗粒的装置,请说出该装置的用途并说明原理,写出化学反应方程式。有时潜艇也用KO2代替Na2O2,这有什么好处?试通过简单分析说明。

A typical application of this (71) is ADSL. It is emerging as the technology for home-and small-office Internet connectivity. It provides either 1.5 Mb/s~8 Mb/s from the network to the user and 64 Kb/s~512 Kb/s in the reverse direction depending on the distance, 12 000 or 18 000 feet.. The different speed for each direction gives it the (72) label. ADSL is designed to take advantage of the fact that video-on demand, telecommuting, and Internet access traffic are inherently asymmetrical. The user (73) a brief message up to the network and receives a ton of data coming back, either a movie or a piece of data download. Under such a scenario, low-speed traffic to the network is just fine. ADSL delivers high (74) where you need it and only uses a single copper pair. Through multiplexing, it also reserves (75) of the bandwidth for POTS.

A.channel

B.computation

C.speed

D.bandwidth
