She put Baglioni's medicine to her lips and took a small sip. At the same moment, Rappaccini came out of his house and walked slowly toward the two young people. He spread his hands out to them as if he were giving them a blessing.

5The distribution patterns of rare earth element compositions in the hydrothermal components are similar to that of pacific seawater. This infers the complex and significant interactions of hydrothermal fluid with surrounding seawater during its diffusing process. Dissolved trace metals in the hydrothermal fluid can be removed by settling terrigenous or biogenic particulates and precipitated quickly from the hydrothermal plume round the vent. On the other hand, hydrothermal particulates would also scavenge some elements from the seawater to coprecipitate into the sediments.

5岩芯沉积物中热液源组分携带的稀土元素组成具有类似海水的分布模式,反映了热液流体喷出海底后与其它物源物质之间的复杂的相互作用:一方面大量生物和陆源碎屑物质的快速沉积导致溶解态的热液源物质被快速清扫,无法向外扩散,快速堆积在热液喷口附近;另一方面,随热液羽状体向外扩散的颗粒态热液源物质也清扫海水中的元素共同进入沉积物。

With the rich sediments supplied by the Pearl River, under the paleogeography sedimentary background of Baiyun Sag continuously subsiding, with sedimentary sequences related to relative transgressive sea level change ,contrary to regressive eustasy, the Pearl River Deepwater Fan System has specific evolution characteristics, which left the sedimentary record controlled by peripherical significant geological events. The sharp change of deposition rate and lithologic geochemical characteristics about 23.8Ma sequence boundary demonstratesd that sediment source had changed, perhaps related to the uplift of Tibet plateau and spreading of the South China Sea, which led the paleoPearl River drainage to expand to western China plateau , maybe much broader than present.

珠江深水扇系统以珠江为沉积物源、以持续深沉降的白云凹陷为沉积古地理背景、以与全球海退型海平面相反的相对海侵型海平面变化的沉积层序构成了其发育演化的特殊性,并留下了控制沉积的周边重要事件的记录。23.8 Ma等界面沉积速率和岩石地球化学特征均有突变,反映出物源区的变化,可能折射出与青藏高原隆升、南海扩张有关的重要事件,使得古珠江骤然向西部高原拓展,甚至较今天的珠江流域范围还广阔;承载珠江深水扇系统的白云凹陷持续沉降形成了陆坡内盆地,导致21~10.5 Ma BP多个层序深水扇垂向叠置充填的特殊沉积建造;根据60多口井资料建立的相对海平面变化曲线,具有与全球海平面变化相一致的三级旋回和不一致的二级旋回。

The purple heather still extends for miles, with its barrows and aerial spectacles, intersected with sandy uneven roads, just as it did then; towards the west, where broad streams run into the bays, are marshes and meadows encircled by lofty, sandy hills, which, like a chain of Alps, raise their pointed summits near the sea; they are only broken by high ridges of clay, from which the sea, year by year, bites out great mouthfuls, so that the overhanging banks fall down as if by the shock of an earthquake.

现在的尤兰仍然和那时一样,它深黄色的荒地,它的古冢,它的海市蜃楼和它的一些交叉的、多沙的、高低不平的道路,向天际展开去。朝西走,许多河流向海湾流去,扩展成为沼泽地和草原。环绕着它们的一起沙丘,像峰峦起伏的阿尔卑斯山脉一样,耸立在海的周围,只有那些粘土形成的高高的海岸线才把它们切断。浪涛每年在这儿咬去几口,使得那些悬崖绝壁下塌,好像被地震摇撼过一次似的。

The shear layer vortices dominate in the initial portion of the jet, which are a result of the K-H instability. The crossflow encounters an adverse pressure gradient ahead of the jet and separates to form horseshoe vortices under the pressure downstream, and they develop into the wake. The wake vorticity comes into being in the actions of an adverse pressure gradient and a wall-normal component of vorticity, which originates from the wall boundary and is entrained into the jet. The shear layer vortices encounter adverse pressure gradients in the lee of the jet and break down, leading to the formation of the CVP and the CVP is the most important characteristic of the jet in crossflow.

文中指出:剪切层涡源于射流与横流之间的K-H不稳定性;马蹄形涡的产生是由于射流喷口上游迎风侧的壁面边界层内存在逆压梯度,使流动发生了分离,在下游逆压梯度的挤压作用下,形成了马蹄形涡,马蹄形涡向下游发展,进入尾迹区;在逆压梯度和法向涡生成项的共同作用下产生了尾迹涡,尾迹涡源于壁面边界层,止于射流,并将部分涡量向上输运至射流内部的CVP;CVP是横向紊动射流的重要特征,剪切层涡破裂后,在逆压梯度的作用下CVP形成。

The billows, torn and lashed by the wind, encompass him hideously; the tossings of the abyss bear him away; all the tongues of water dash over his head; a populace of waves spits upon him; confused openings half devour him; every time that he sinks, he catches glimpses of precipices filled with night; frightful and unknown vegetations seize him, knot about his feet, draw him to them; he is conscious that he is becoming an abyss, that he forms part of the foam; the waves toss him from one to another; he drinks in the bitterness; the cowardly ocean attacks him furiously, to drown him; the enormity plays with his agony.

迎风崩裂的波涛狠狠地包围着他,波峰波谷带着他辗转上下,一缕缕的白练飞腾在他的头上,一阵阵的狂澜向他喷唾,巨浪的口把他吞没殆半;他每次下沉,都隐约看见那黑暗的深渊,一些未曾见过的奇怪植物捉住他,缠着他的脚,把他拉向它们那里去;他觉得自己也成了旋涡,也成了泡沫的一部分,波涛把他往复抛掷;他喝着苦汁,无情的海水前仆后继,定要把他淹没,浩瀚的泽国拿他的垂死挣扎来取乐。

The particles with heavy specific gravity are discharged from the underflow mouth and those with light specific gravity are discharged through the overflow pipe and thus it realizes the separation for heavy and light particles.

流体自旋流器上端给入并在旋流器内形成强制旋转流,旋转流将颗粒按粒度和比重分为内外环层,当矿浆流动至锥体部分时,由于锥体的突然变向,阻力增大,颗粒群向下运动的趋势减缓,并在此形成旋转悬浮层,随着离心力场的减弱,重力作用越来越明显,由按粒度和比重分成的内外两层逐渐转化为按比重分选的上下两层,比重大的颗粒通过底流口排出,比重小的颗粒则通过溢流管排出,从而实现轻重颗粒间的分离。
