古代社會(huì)知識(shí)的傳播.
A diffusion of ancient social knowledge
古代知識(shí)傳播的狀況:古代知識(shí)的傳播可以用一個(gè)詞來(lái)形容:緩慢,在過(guò)去一項(xiàng)科學(xué)知識(shí)的傳播都要經(jīng)歷了數(shù)百乃至數(shù)千年
the spread situation of the Ancient social knowledge:we can use one word to describe the transmission of the Ancient social knowledge:slow.In the past,the spread of a scientific knowledge must experience hundreds of thousands of years.
例如:印刷術(shù)早在公元200年就產(chǎn)生在中國(guó)并得到了發(fā)展和廣泛的運(yùn)用.但是在壹千多年后才傳播到了歐洲;
For example:in A.D.200 ,printing was invented,developed and widely used in China ,but it wasn't spread to Europe until one thousand years later;
玉米的種植技術(shù)1000多年前就出現(xiàn)在美洲,但在哥倫布發(fā)現(xiàn)新大陸后才流傳至歐洲和中亞.
the technology of corn planting first appeared in America about a thousand years ago ,but it was not until Christopher Columbus discovered the new continent that it was spreaded to Europe and central Asia.
這一切都是一個(gè)緩慢的過(guò)程,那么,為什么古代知識(shí)的傳播會(huì)如此之慢呢?什么是古代知識(shí)傳播的障礙呢?下面有請(qǐng).為大家講解.
All of this is a slow process.So,why is it that the diffusion of knowledge should be so slow?What are the obstacles that hold it back?
