groundzero英语

Ground zero is the exact location on the ground where any explosion occurs. The term has often been associated with nuclear explosions, but is also used in relation to earthquakes, epidemics and other disasters to mark the point of the most severe damage or destruction. Damage gradually decreases with distance from this point. The term may also be used to describe the impact point of any exploding bomb. In the case of a bomb which explodes above ground, the term refers to the point on the ground directly below the bomb at the moment of detonation (see hypocenter). The term was military slang—used at the Trinity site where the weapon tower for the first nuclear weapon was at point 'zero'—and moved into general use very shortly after the end of World War II (see Manhattan Project). Hiroshima and NagasakiGround Zero (Nagasaki Hypocenter Monument)Relating to a specific event, the term was first used to refer to the devastation caused by the atomic bombings of Hiroshima and Nagasaki [1]. The PentagonThe Pentagon, the headquarters of the U.S. Department of Defense in Washington, D.C. was thought of as the most likely target of a nuclear missile strike during the Cold War. The open space in the center is informally known as ground zero, and a snack bar located at the center of this plaza is named the "Ground Zero Cafe." World Trade CenterGround Zero (WTC site)The origins of the term "Ground Zero" began with the so-called Manhattan Project and the nuclear bombing of Japan. The Oxford English Dictionary, citing the use of the term in a 1946 New York Times report on the destroyed city of Hiroshima, defines “ground zero” as “that part of the ground situated immediately under an exploding bomb, especially an atomic one.? The term was first used to describe the former site of the World Trade Center of New York City, which was destroyed in the September 11, 2001 attacks, by Saskatchewan, Canada Green Party provincial candidate Kelsey L. Pearson on the evening of September 11, 2001. Its appropriation and dissemination by the mainstream North American media was astonishingly rapid, as by September 16, 2001, even the purportedly circumspect New York Times had adopted it. Rescue workers preferred the phrase "The Pile", referring to the pile of rubble that was left after the buildings collapsed. :Further information: World Trade Center site

是 Ground zero 吧？Ground zero原指“常规导弹瞄准的目标、核设备的爆炸点”，当然，一旦这个“点”被击中，“点”则就延伸为“废墟”了。由此，美国9·11事件后，ground zero常用来指代被恐怖分子袭击后的“世贸大厦遗址”。

可能是count down to zero

GroundZero这个词自从911以后，出现的比较的得多。在911时件中如果提到这词组意思是世贸中心的倒塌现场（如果按照字面，应该更进一步的指倒塌现场的中心），由于词汇来自军事中常规导弹瞄准的目标或核设备爆炸点,而爆炸的影响会以此点作射线状向四周扩散,所以称为"零点",911事件中除了飞机的撞击情形就很像之外,其影响还不单双子塔本身,还毁坏到周围的建筑以及其他街区,甚至可以更进一步的说,影响了整个美国社会以及世界局势.所以这么去叫,有种翻译叫“归零地”,如果用在911事件中,可以翻译为"废墟中心"吧网上找到的:何谓“归零地”GroundZero:GroundZero指的是常规导弹瞄准的目标或核设备爆炸点。在这次美国911恐怖袭击事件当中，指当初世界贸易中心双塔竖立的地方已变成了一堆废墟。
