俯冲

Its swooping form, which suggests two boomerangs placed side by side, has been compared to a dragon.

它那俯冲式的形状，由两根回飞棒并列排放，就像是一条巨龙。

Cavorting and diving at breathtaking speeds, the beautiful birds mirrored each other in flight.

在空中翻飞嬉戏，又作闪电式俯冲，矫健的鹰双双比翼齐飞，形影相随。

Cavorting diving at breathtaking speeds, the beautiful birds mirrored each other in flight.

在空中翻飞嬉戏，时作闪电式俯冲，矫健的鹰双双携游于碧空。B。

They stooped in a long curve down into the golden glow, concentrating, cawing, wheeling, like back flakes on a slow vortex, over a tree clump that made a dark boss among the pasture.

它们作弧线状俯冲进金色的余辉，围着一块乌黑的树桩盘旋，如同缓慢的旋风卷起黑色薄片。

Accompany with the subduction of Pacific and Indian plates, upper mantle convected more violently, and new upwelling astheosphere replaced and eroded the lithosphere, and resulted in irregular thinning of cloud-like mantle along reticulated or dondroid weak zones. The thinning was dominated by replacement of lithosphere with new upwelling astheosphere, and accompanied possibly by delamination.

在这过程中，特别是伴随太平洋、印度洋板块的俯冲作用，地幔对流加剧，上涌的新生软流体顶蚀置换岩石圈，从而造成了沿早期业已存在的幔内薄弱带网络，出现类以&蘑菇云状&的地幔不规则减薄，这种减薄以新生软流体取代岩石圈为主，并可能伴随一定程度的岩石圈拆沉作用发生。

Bridge, though it was lined with cubbies of Taelon flight engineers and contained by the occasional swooping,graceful structural member, offered a view that was anything a T aelon could want.

舰桥上，一排泰星飞行器停泊在那里，驾驶员按照泰星人的指示俯冲而下，在那些优雅的护栏边稳稳的着陆。

The break-off and cumulates of subducted slab would give rise to the upwelling of mantle material and then thermal -chemical erosion of lithospheric roots happened.

俯冲板片断离及在深部地幔中的堆积，必然引起地幔物质的对流，从而产生地幔羽，上升的地幔羽对岩石圈底部发生热侵蚀和化学侵蚀，并在薄弱地带上升喷出地表或侵入在地壳浅部，形成了广泛而强烈的岩浆作用。

For Southwestern Margin of Aqikekule Lake ophiolite, their field geological, petrological, minerological, petrochemical and geochemical characteristics show that:① it outcropped as tectonic slices along the near west-to-east strike Kunzhong fault and is composed of metamorphic perodotties, cumulates and volcanic rocks, in which, chromites are distributed in the upper part of metamorphic peridotites as pods, or in the lower part of cumulates as near-strata;② metamorphic peridotites include serpentinites, chromite-bearing serpentinites, chlorite-epidote schists and chromitites, of which, chromitites have nodular and orbicular structure, and cumulates include pyroxenits, serpentinites, chromite-bearing serpentinites, chromites and metamorphically mafic rocks and only basalts are seen in volcanic rocks;③ Cr# of chromites suggest that they formed in the SSZ and Al〓O〓 and TiO〓 of metamorphic peridotites also suggest SSZ environment;④ metamorphic peridotites have V type and enriched LREE patterns, cumulates have from strongly depleted LREE, flat REE to enriched LREE patterns with universally striking positive Eu anomalies and basalts show flat REE or slight enriched LREE patterns with no Eu anomalies;⑤ trace element and Sm-Nd isotope characteristics of metamorphic peridotites imply their strikingly heterogeneous mantle character ε〓(t+4.39～+26.20 and later Nb, Ta fertilization;⑥ trace element characteristics of basalts and their tectonic diagrams show they probably formed in the rifted island arc or back-arc basin environment.

对阿其克库勒湖西南缘蛇绿岩，野外地质、岩石学、矿物学、岩石化学以及地球化学等特征表明：①该蛇绿岩以近东西向、沿昆中断裂呈构造岩片出露，由变质橄榄岩、堆晶岩和火山岩三个单元组成，其中见铬铁岩呈豆荚状产于变质橄榄岩的上部，或呈似层状产于堆晶岩的下部；②变质橄榄岩包括蛇纹岩、含铬铁矿蛇纹岩、绿帘绿泥片岩和铬铁岩等类型，其中，豆荚状铬铁矿具有结核状构造和球状构造，堆晶岩包括辉石岩、蛇纹岩、含铬铁矿蛇纹岩、铬铁岩和变质基性岩等类型，火山岩仅见玄武岩；③铬铁矿的Cr#表明其形成在俯冲带，变质橄榄岩的Al〓O〓和TiO〓成分也指示了SSZ环境；④变质橄榄岩的稀土配分型式见V型和LREE富集型两种型式，堆晶岩表现出从LREE强烈亏损、REE平坦分布到LREE富集的配分特征，并且普遍具有醒目的正Eu异常，玄武岩的稀土配分型式表现为平坦型或LREE略富集，无Eu异常；⑤变质橄榄岩的微量元素及Sm-Nd同位素特征指示了其地幔的显著不均一性ε〓(t为+4.39～+26.20以及Nb、Ta在后期的富集；⑥玄武岩的微量元素特征及构造图解表明其可能形成在裂谷岛弧或不成熟的弧后盆地环境。

Still feel in cuttlefish great dallies with seabird during, mew dives and fall, hold cuttlefish readily.

还在乌贼觉得得意地玩弄海鸟之际，海鸥俯冲而下，一口把乌贼叼走了。

Ferapontov's wife alternately dandled and soothed her baby, and asked in a frightened whisper of every one who came into the cellar where was her husband, who had remained in the street.

又响起了嗖嗖的呼啸声，但这一次离得很近，好像飞鸟俯冲一样，只见街心火光一闪，不知什么东西爆炸开了，顿时街上弥漫着硝烟。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
