Using muscle samples taken from the powerful hind legs of locusts, Lovejoy and his colleagues used mitochondrial DNA sequences to reconstruct the evolutionary history of the Schistocerca locusts.

影响蝗虫飞行的因素应该有很多。拉夫卓伊指出，当时的高空气流对蝗虫群的飞行就至关重要。

There are larks singing in the shadows of flowers under the timbo melon trellis ; There are doves whistling in a slivery voice in the air.

树藤瓜架下的花影里，有百灵的叫声；高空中有清越的鸽哨。

And when night came, and the river rushed on unseen, save for a glint of high stars mirrored in dark pools, then he rested, and slept; for he felt no fear beside that water, in which the power of Ulmo ran.

当夜幕降临、除了高空星辰倒映在暗处池塘中的微光再也看不见奔流的河水时，他停下休息并睡着了；因为在那涌动着Ulmo力量的水流边他不感到恐惧。

It proved that the model can be used to analyze the propagation characteristics, optimize the modulation and coding schemes and performance simulation of the HAPS communication systems.

证明该模型可用于高空平台站通信电波传播特性的分析、调制及编码方案的优化和通信系统性能仿真等方面的研究。

The plastic worm is ideal for this, even the most sluggish bass will respond when you drag one slowly past its nose.Crank baitsWhen fishing a tidal river for bass, cast crank baits near the mouths of tiny feeder streams on the falling tide.

For the last hour we've been stooging around at 25,000 feet, waiting for the enemy planes.

在过去的一小时里，我们一直在25，000英尺的高空盘旋，等待敌人飞机的到来。

This paper described the mechanism of the aero-engine windmilling drag, and theoretically deduced the formula for determining it in the simulated altitude test, and finally the experimental method for determining the engine windmilling drag was introduced.

本文分析了航空发动机风车阻力的产生机理，推导了发动机高空台试验中风车阻力确定的计算公式，介绍了航空发动机风车阻力确定的试验方法。

In order to solve the problem of engine starting characteristics calculation under windmilling condition, a generalized format of engine starting nonlinear mathematical model based on liner-in-parameters model was given.

针对高空风车条件下航空发动机起动性能估算问题，给出了用线参数模型描述发动机风车起动非线性过程的一般形式，利用约简遗传规划算法进行模型结构选择的思路，建立了基于约简遗传规划的航空发动机起动性能计算模型。

After becoming lost in a thick cloud bank at 14,500 feet, the plane was never heard from again and its wreckage.Including the nuclear cores, it was never found.

在从1.45万英尺的高空失踪之后，美国空军没有再听到有关这架B-47的任何消息，而包括核芯在内的飞机残骸也未找到。

The plane will include four computers, two copying machines, conference rooms, crew bunks, sleeper chairs, a press room with TV monitors, and secure phone lines that can rouse U.S. network anchormen from anyplace on the earth and 45,000 ft. up.

机上还有四台计算机、两部复印机、会议室、机组人员铺位、躺椅、装有电视监视器的记者室以及不论在地面还是在四万五千英尺高空均可随时随地呼唤美国广播网现场报道员的安全可靠的电话线路。

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。
