英文寫(xiě)作翻譯頻道為大家整理的雅安大地震英語(yǔ)作文：地震的預(yù)警時(shí)間，供大家參考:)
從唐山地震人們的感受來(lái)看，從地震發(fā)生到房屋破壞，時(shí)間雖然短暫，只有十幾秒鐘，但仍可以大致劃分出三個(gè)不同的階段；
From the Tangshan earthquake people's experience, from the earthquake damage to housing, time is short, only a dozen seconds, but still can be roughly divided into three different stages;
1、地面微動(dòng)（先顛），一般伴有聲、光等現(xiàn)象，即預(yù)警現(xiàn)象出現(xiàn)；
1, the Ground Microtremor (to Britain), generally associated with sound, light and other phenomena, is warning phenomenon;
2、地大動(dòng)（后晃）；
2, large dynamic (back and forth);
3、房屋倒塌。
3, the collapse of the housing.
也就是說(shuō)，從地面開(kāi)始微動(dòng)到房屋倒塌，有十幾秒的時(shí)間差。
That is to say, from the Ground Microtremor to houses collapsed, has more than ten seconds of time difference.
為什么會(huì)這樣呢？因?yàn)榈卣鸩ㄒ鸬牡孛嬲駝?dòng)是一種復(fù)雜的運(yùn)動(dòng)，它是幾種波共同作用的結(jié)果。但就人們的感受而言，主要可區(qū)分出上下顛動(dòng)和水平晃動(dòng)兩種形式。在強(qiáng)烈地震的震中區(qū)附近，最初的顛動(dòng)，是由首先到達(dá)的縱波引起的；數(shù)秒鐘以后，橫波就以忽上忽下、左右搖擺的運(yùn)動(dòng)方式到達(dá)，造成更強(qiáng)烈的地面垂直和水平振動(dòng)，因而人們就感到像站在風(fēng)浪中的船甲板上一樣劇烈顛簸。這就是人們感到“先顛后晃”的原因。
How so? Because the ground vibration caused by earthquake wave is a complex exercise, it is the result of joint action of wave. But the feeling of people, mainly to distinguish leapt and horizontal shaking two forms. In the area near the epicenter of strong earthquakes, the initial litter, is caused by the first wave arrived; the number of seconds later, shear wave in movement up and down, swing around the arrival, resulting in more strong vertical and horizontal ground vibration, so people feel like standing in the wind waves on the deck of the boat as rough. This is people feel "reason to Britain after.".
地面運(yùn)動(dòng)會(huì)使房屋受到慣性力的作用，就好象在高低不平的路上行駛的汽車緊急剎車，車上的乘客就會(huì)感到上下跳動(dòng)和水平晃動(dòng)一樣。這種由地震波使房屋所受到的慣性力，叫做地震力。
Ground motion so that the building was the effect of the inertia force, as if in the rugged road vehicle emergency brake, the passengers will be jumping up and down and the level of shaking. The seismic wave to housing by the inertia force, called the earthquake force.
由于地震波引起的地面運(yùn)動(dòng)有一個(gè)由弱到強(qiáng)的過(guò)程，房屋受力后的破壞也有一個(gè)由小到大、由晃到倒的過(guò)程，這樣，就形成了地震破壞過(guò)程的“三步曲”。
Because the process of ground motion caused by earthquake wave is a weak to strong, houses destroyed after the stress also has a small to large, from side to the reverse process, so, on the formation of the three steps of seismic damage process "".
從人們發(fā)現(xiàn)預(yù)警現(xiàn)象開(kāi)始，到房屋倒塌，這個(gè)時(shí)間差，稱為大震的預(yù)警時(shí)間。預(yù)警時(shí)間的長(zhǎng)短，主要取決于震中距（在地面上，從震中到任一點(diǎn)的距離叫做震中距），同時(shí)也與建筑物條件，人們震時(shí)所處的狀態(tài)和發(fā)現(xiàn)預(yù)警現(xiàn)象的早晚等多種因素有關(guān)。不同地震、同一地震的不同烈度區(qū)，預(yù)警時(shí)間不盡相同。
From the people find warning phenomenon began, to the collapse of the housing, this time difference, known as the large earthquake early warning time. The warning time, mainly depends on the epicentral distance (on the ground, from the epicenter to any point is called the epicenter distance), and at the same time and building conditions, a variety of factors which people when the earthquake early warning state and found the phenomenon of sooner or later. Different intensity areas different earthquake, the same earthquake, warning time is not the same as.

According to the survey of Tangshan after the earthquake, in order to be able to make the basis of estimation of statistics, 177 cases of early warning time, most be awaked to provide early warning time is only several seconds, warning time up to provide earthquake sobriety of ten seconds, few can reach more than 20 seconds. Accounted for 83% in 20 seconds, the average warning time of 13.6 seconds. Such as the intensity statistics, in the ten time zone (138 cases), an average of 12.8 seconds; ten degree (39 cases), an average of 16.3 seconds. Thus a rough estimate, Tangshan earthquake early warning time is about 10 to 20 seconds.
