2018年英語專四考試聽力臨考衝刺

Helped by one of his students, professor Kent Harries is testing a bamboo pole for its radio load,how much of a pressure or wave it can withstand.

在一位學生的幫助下,Kent Harries教授正在測量竹竿的無線電負荷能力。探究其能負荷多強的電壓和電波。

Building codes everywhere require strict standardization of tests for all materials, such as timber or tests for bamboo have not been standardized even though the strength of at least three species is comparable to steel.

各地的建築準則均規定,像木材或是混凝土等所有的建築材料,都要進行嚴格的標準化檢測。但是如今對竹子這種材料還沒有一定的檢測標準,儘管目前至少有三種竹子的建築價值與鋼鐵不相上下。

“They are remarkably strong which are marked, the resilient, it’s optimized to be a very tall, obviously bamboo material,something like this, might grow 20 it supports its own weight,and of course it also supports huge wind loads in what knocks over that.”

“竹子質地明顯很硬,彈性極強,非常適合做一些長的竹材料。比如像這個東西,能長到20米長。”它也能承受自身的重量,而且受到任何撞擊時,它也能承受強大的風壓。”

Bamboo is widely used as food for pandas, for forniture or engineer products, such as plywood, glue laminated and cross laminated not much outside its native growing area, mostly because of its round cross section. But there are other reasons too.

竹子通常可做為熊貓的食物,也可以用來做傢俱或是一些設計產品。比如膠合板、膠合木材和交叉複合木材等。但是竹子一般在其生長地之外的地區用的不多,主要是因為它的截面是圓的。但是除此之外還有一些別的原因。

“With this viewed in much of the world as well bamboo is for poor people, and so there is that mentality that we are trying to get over.”

“世界上大多數地區的`人們認為竹子是窮人才用的,因此我們目前正在盡力克服這種心理。”

Bamboo is suitable for construction (that) requires significantly less resources than comparable ’s highly sustainable, with a harvest cycle of about three years, while soft wood requires about ten, and hard wood more than 30 years.

竹子很適用於一些建造工程,而且明顯比使用木材節約大量的資源。竹子屬於高度可持續能源,其生長週期一般為3年,而軟木一般是10年,硬木生長週期會超過30年。

“If we standardize it, if we provide essentially documentation as test methods which the engineers can hang their hat on,we bring the material into the mainstream.”

“如果我們可以制定標準化程式,釋出必要的檔案規定工程師在檢測時能夠遵循的檢測方法,那麼這種材料將成為一種主流。”

Harries says the standardized bamboo poles could be used in multiple stock columns vertically and for floors and roofs many countries, they are already used for wall panel structures.

Harries稱標準化的竹竿可用於製作多種垂直料柱,平行地板和屋頂。在許多國家,竹竿已用於牆板結構製作中。
