跃

In some years, April bursts upon Virginia hills in one prodigious leap – all the stage is filled at once, whole choruses of tulips, arabesques of forsythia, cadenzas of flowering plum.

有时候，四月一个健步就跃上了弗吉尼亚的小山丘。顿时，整个舞台活跃起来：郁金香们引吭高歌，连翘花翩翩起舞，梅花表演起了独奏。

In some years, April bursts upon Virginia hills in one prodigious leap – and all the stage is filled at once, whole choruses of tulips, arabesques of forsythia, cadenzas of flowering plum.

有那么几年，四月一跃而上弗吉尼亚的山峦，如同一个舞台般瞬间上演着郁金香的合唱，蔓藤植物的妙舞，洋李子花齐奏的华彩。

In some years, April bursts upon our Virginia hills in one prodigious leap——and all the stage is filled at once, whole choruses of tulips, arabesques of forsythia, cadenas of flowering plum.

四月，有时不知怎地一跃，就来到了弗吉尼亚的山坡上——自然的大舞台上转眼到处生机勃勃。郁金香组成了大合唱，连翘展示出优美的舞姿，洋李奏起了华彩乐段。

The dose enhancement effects and decreasing effects caused by material inhomogeneity were studied quantitatively with a parameter named Dose Perturbation Factor, which was the ratio of the dose at a point in the heterogeneous phantom to the dose of the same spatial location point in the homogeneous phantom. It was showed that the degrees of the dose enhancement or decreasing depended on the energy of radiation, field sizes of the beamlets and compositions of the media. The dose perturbation for high energy X rays is greater than that for low energy X rays. At the same energy condition, the dose perturbation decreased when the field size increased. And the relationship between them was not linear.

模拟结果表明：在小射野情况下，异质组织界面处出现了较大的剂量跃变，剂量扰动效应的强弱程度取决于射线的能量、射野的大小和模体介质的不同等多种因素，高能X射线条件下的剂量扰动效应大于低能X射线条件下的剂量扰动；在入射X射线能量相同的条件下，剂量扰动效应随射野尺寸的减小而增强，并呈现一种非线性关系。

We're like a herd of wild horses with blinders over our eyes. On the rampage. Stampede.

我们就像一群眼睛被蒙住的野马，我们狂奔、乱跑，呼的跃下了悬崖。

IT NEVER pays to underestimate the bounciness of Asia's emerging economies. After the region's financial crisis of 1997-98, and again after the dotcom bust in 2001, outsiders predicted a lengthy period on the floor—only for the tigers to spring back rapidly.

低估亚洲新兴经济体的反弹性永远得不偿失。1997至1998年期间，亚洲爆发金融危机，随后又在2001年经历了互联网泡沫破灭，外界都预测亚洲经济会长期处于探底阶段——然而，它们却如猛虎般迅速跃起。

千万不可小觑亚洲新兴经济体的反弹。1997年到1998年，亚洲身陷金融危机，随后2001年又受困互联网泡沫破灭，当时外界都断言，亚洲虎的经济将会长落平阳—岂料，它却迅速地重新跃起。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
