底流

It is shown from the analysis results that in order to meet the requirement that the calculated geostrophic flow results can reflect the practical current profile structure, it is practicable to select the 700 m level as level of no motion in case of water depth greater than 700 m and to select the bottom boundary as level of no motion in calculating the geostrophic flow.

结果表明，为使计算结果可以反映实际的流速剖面结构，当水深大于700 m和小于700 m时可分别选取700 m层和底边界作为地转流动力计算零流面。

Having now recognized that Euripides failed in founding the drama solely on Apollinian elements and that, instead, his anti Dionysian tendency led him towards inartistic naturalism, we are ready to deal with the phenomenon of aesthetic Socratism. Its supreme law may be stated as follows:"Whatever is to be beautiful must also be sensible"--a parallel to the Socratic notion that knowledge alone makes men virtuous.

所以，我们既已详细知道，欧里庇德斯想把戏剧只放在梦境因素的基础上而没有成功，他的非梦境倾向反流为非艺术的自然主义倾向，那末，我们现在要进一步探讨欧里庇德斯的审美苏格拉底主义的性质：他的最高审美原则是"唯知为美"，这可以媲美苏格拉底的格言"唯知是德"。

Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.

From the Late Carboniferous to the Permian, Junggar region into the post-collision tectonic evolution stage, in the stage of the post-collision, the early subduction slab rupture and separate, asthenosphere decompression melting, basalt magma take place underplating, because the underplating of the basalt magma, low crust melt by the high temperature forming the acid crust-magma, the basic magma from mantle and acid one from crust mixing at the vicinity of the crust-mantle boundary, formed the Huangyangshan magma mixing plution, the dioritic microgranular enclaves are the recorder of the crust and mantal magma mixing process.

从晚石炭世到二叠纪，准噶尔地区进入后碰撞构造演化阶段，在后碰撞构造阶段，早期的俯冲板片断离，软流圈减压熔融，玄武质岩浆底侵至下地壳底部，底侵基性岩浆带来的巨大热量，导致地壳物质熔融，形成大规模的花岗质岩浆，两种岩浆在壳-幔边界附近发生不同程度的混合，其中闪长质微细粒包体就是基性的幔源岩浆和酸性的壳源岩浆不同程度的混合的记录者。

The most popular during the Shang Dynasty was the "bird and beast" design,hu,(long-necked and small opening, deep-bellied with round base, some with overhanging handle),you (elliptic opening, deep-bellied with round base, has a lid and overhanging handle), lei (some round and some square, openings vary in size, short neck with square shoulders, deep bellied, with curling feet or round base, and has a lid), fou and the like are wine vessels, jue (deep-bellied, tri-pedestal, can be heated on top of fire, protruding grooves at the top for easy pouring), gu (the most common wine-drinking utensil, more often used in combination with jue, which is bigger, opening is shaped like a bugle, long neck, thin waist, tall curling feet), zh(similar to the zun in shape but smaller, some with lids), gong (oval belly, has an outer edge for flow of wine, short handles, bottom has curling feet, lid is in the shape of the head of a beast, some has an entire body like a wild animal, with small spoon as accessory), bei, zhen is to drink from.

尊（鼓腹、敞口、高颈，底有圈足，形制较多，商代以鸟兽形尊最为流行）、壶（长颈、敛口，有的有盖，深腹圆座，有的有提梁）、卣（椭圆口，深腹圆座，有盖和提梁）、罍（有圆形和方形，口大小不一，短颈方肩、深腹，圈足或圆底座，有盖）、缶等是盛酒的器具，爵（深腹、三足，可在火上加温，上端有伸出的沟槽以倒酒）、觚（最常用的饮酒器，多与爵相配使用，比爵小，口呈喇叭状，长颈、细腰、高圈足）、觯，觥（椭圆腹，有流酒的外沿和短提把，底为圈足，有兽头形盖，也有整体为兽形的，并附有小勺）、杯、盏是饮酒的器具。

The author has made a detailed analysis of the satellite gravity data over Wenchuan, Motuo, Zhongba, Jiashi and Taiwan Areas in China, where earthquakes more than magnitude of 6 took place in recent several decades. It is surprising that the gravity field patterns over these areas are extremely similar, which is characterized by the following features:(1)Paired positive and negative anomaly.(2)Epicenters usually were located between the pairs where the gradient of gravity field was the steepest.(3)The value of positive peak increased and its width decreased at higher order field.(4)The distance between positive and negative peaks varies in different tectonic background.(5)Different styles of crustmantle material diapirism in different stress fields. Geologically, rheological diapirism of high density crustmantle material could be a reasonable explanation to this unique pattern.

笔者详细分析了中国汶川、墨脱、仲巴、伽师和台湾等地的卫星重力资料(这些地区在近几十年来均发生过6级以上的大地震)，惊奇地发现，在这些地区，卫星重力场的样式具有极大的相似性，它们表现在：(1)卫星重力场的正负异常值成对出现；(2)震中通常位于重力场峰值间的陡梯度带；(3)由低阶到高阶的重力场正异常的峰值增大而宽度变窄；(4)正、负峰值间的距离随所处的大地构造背景而变；(5)不同应力场壳幔物质底辟的样式不同，从地质上看，高密度壳幔物质的流变底辟作用，可以合理地解释这种独特的样式变化。

Weigh's addition minishes the loss of net's volume in pure current, but makes no differnce in the pure wave condition. After installed of sinking ring or lower ring, the loss of net's volume is decreased. The loss of net volume is more in the current combined with wave condition than in the pure current condition.

在纯流条件下，增大配重均有利于减小网箱的体积损失；而在纯波条件下，配重的增加对于改善网衣的变形没有实质性的意义；设置了底圈或沉降圈后，均能在一定程度上减小网衣的体积损失；波流组合条件下网衣的体积损失要明显大于纯流条件下的体积损失。

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。

Pan bottom consists of dry and wet surfaces.When heated,the pan produces vapor to sterilize.Reaching the cold bottom of condenser,vapor will be condensed into water and drained back into pan.When the temperature in condenser reaches 90℃,vapor will be released from the vent devised with a whistle alarm.

底锅分为干表面和湿表面二部分，加热时可产生过热的高温蒸汽进行灭菌，当蒸汽进入冷凝器底部时，则遇冷被冷凝成水，经回水管又流回底锅，水———汽在锅内闭路循环，直至冷凝器中水温达到90℃以上时为止，此时蒸汽则通过出气管外逸，吹动哨片发出响声报警。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
