半时

In the 1890s, for example, says Kerry Taylor, a fashion expert and vintage clothing auctioneer,"when women were very heavily corseted there was a real vogue for oriental tea gowns; they were semi-formal and a woman would wear one when receiving a guest."

时尚专家、古董衫拍卖商凯丽泰勒举例称，在19世纪90年代&女性仍穿着非常束缚的紧身胸衣时，就曾流行过东方风格的茶会女礼服：女士们在接待客人时会穿着这种半正式的礼服&。

The results showed that: at metaphase I, the homoeologous chromosome pairing among different F1 hybrids ranged from 2.0 to 11.4 bi-valents formed by homoeologous chromosomes per pollen mother cell, and very few multivalents, and even very few bivalents were formed by two chromosomes within one genome rather than homoeologous chromosomes in some PMCs; at anaphase I, all biva-lents were disjoined and most univalents were divided.

结果表明在中期I阶段，这些杂种一代的近缘染色体联会变化很大，每个花粉母细胞中二价体形成的数目从平均2个到11.4个不等，甚至在某些花粉母细胞中，还发现极少的多价体和非部分同源染色体所形成的单基因组内二价体；在后期I时，所有的二价体分离，同时多数单价体也分离，分离的二价体和分离的单价体都移向两极，从而形成两组染色体；因为这时完整花粉母细胞中分离的二价体在两组染色体中总是对应出现，从而根据半二价体上染色体重组的位置可以分析在二价体的四分体时期发生在非姊妹染色体之间的多种染色体交换类型，如单交换、三线双交换、四线双交换、四线三交换和四线多交换。

That's after firefighters arrived at about 1:30 a.m. to find flames engulfing the buildings.

凌晨1点半，消防队员到达时发现大火吞噬了整个建筑。

All additions rapidly decreased silage pH under different DM contents of M.sativa.M.sativa(DM 38.45%) ensiled with lactic acid bacteria+cellulase gave the best results: ammonia nitrogen content was reduced,and most CP was conserved and most lactic acid produced.

结果表明，不同干物质含量的苜蓿青贮时，乳酸菌+纤维素酶的添加均能使青贮pH值快速下降；苜蓿半干青贮(干物质含量为38.45%)可使青贮氨态氮含量显著降低，并保存有较多的粗蛋白质，生成较多乳酸，其中以添加乳酸菌106 cfu/g+纤维素酶0.05 g/kg的青贮效果最好，其青贮综合评定得分最高，达93分。

And there's so many gringos over there buying "cheap" gasoline, that by the time I got back over the bridge and through customs, the tank was half empty.

那边想买点便宜油的美国佬太多了，以至于我回来过桥过海关时，只剩半箱油了

As he sleeps, his tiny chest heaves and the translucent fingertips of his right hand open and close over his crumpled face.

当他睡着时，小小的胸口起伏着，右手上戴着的半透明的指套贴着他皱皱的小脸。

The first half of the river crossing seems manageable, just, but then, watch this, the SUV has water rising to way above its wheels and it hobbles across – a clear sign that large rocks are underneath.

河的前半段似乎还能对付，但说时迟那时快，注意看，河水一下子漫过了这辆运动型多功能车的车轮，它在河水中蹒跚而行，很明显水下有些大石头。

In order to probe the relationships between wave equation offset domain common image gathers/angle domain common image gathers with migration velocity, we quantitatively derive the changes of ODCIGs and ADCIGs along with migration velocity on the assumption of uniform velocity medium with a horizontal reflector. We come to conclusion that ODCIGs are hyperbolas with half offset; on the contrary, they are ellipses. Combined with the results of depth focusing analysis, we find the apparent incident angles in ADCIGs are larger than the real incident angles when the migration velocity is larger than the true one and vice versa. With lower migration velocity, the residual moveout on ADCIGs is an ellipse with the tangent of apparent incident angle; otherwise, it's a hyperbola.

为了得到波动方程偏移距域共成像点道集和角度域共成像点道集与偏移速度的关系，在匀速单层水平反射情况下，对ODCIGs和ADCIGs随偏移速度的变化进行了定量的推导，得到偏移速度偏小时ODCIGs与半偏移距成双曲关系，反之成椭圆关系；结合深度聚焦分析，得到偏移速度偏大时ADCIGs中视入射角大于真入射角，反之，小于真入射角；在速度偏小时，ADCIGs上剩余时差与视入射角的正切值成椭圆关系，反之成双曲关系。

All day the fire-steed flies over the country, stopping only that his master may rest, and I am awakened by his tramp and defiant snort at midnight, when in some remote glen in the woods he fronts the elements incased in ice and snow; and he will reach his stall only with the morning star, to start once more on his travels without rest or slumber.

一整天，这火驹飞过田园，停下时，只为了它主人要休息。就是半夜里，我也常常给它的步伐和凶恶的哼哈声吵醒；在远处山谷的僻隐森林中，它碰到了冰雪的封锁；要在晓星底下它才能进马厩。可是既不休息，也不打盹，它立刻又上路旅行去了。

Second,we investigated the temporal and spectral properties of the THz emission of a novel semi-insulating GaAs interdigitated photoconductive antenna with different excited carrier densities,in a temperature range from 4.2K to 270K.

其次，我们研究了一种全新的微结构半绝缘GaAs光导天线THz辐射的时域和频域特性，特别是其在从4K到270K的温度变化范围内的THz发射特性。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
