深度

It was not the depth of a stringed instrument, or of a drum, but the depth of a human voice alive to the significance of words made holy by time and usage.

那些词语的声音很有深度，不是弦乐或鼓的深度，而是人的声音由于意识到词语的意义而获得的深度，那些词语在历经了岁月和使用之后而变得神圣。

In the shallow soil with the depth of 0~50 cm below the ground surface,the extent from 0 to 50 centimeters, the change of the δ13C of the soil carbonate is positively related with the depth in the upper soil profile from 0~30 cm,but it will increase rapidly in the lower soil profile as the result of the existence of salined and alkali soil layer.

盐碱化土地在0～50 cm的深度范围内，土壤碳酸盐的δ13C值变化规律为：0～30 cm深度内，土壤碳酸盐的δ13C值随深度的增加而逐渐减小；在30～50 cm范围内，如果有盐积层或碱积层的存在，则土壤碳酸盐的δ13C值迅速增加。

Limiting the time term's test shows that the influence is very small to the judgment influence of the sense of vision depth of the athlete, for common high school student the influence is very clear. As the member of team in different position, the total ascending has the certain difference; the depth sense of vision level of the forward in totally higher than vanguard and rearguard, the vanguard is total with the depth sense of vision level of the rearguard ascend did not show the very difference.

限定时间条件对运动员的视觉深度的判断影响很小，对于普通中学生影响显著。15年龄段场上不同位置的队员的视深能力总体上有一定的差异；前锋的深度视觉水平在总体上要高于前卫和后卫，前卫和后卫的深度视觉水平总体上没有显著差异。

The results showed that the lesion of X-rays oncells displayed gradually attenuation with depth (or cellsurvival fraction displayed gradually increase with depth)while the lesion of heavy ions on cells followed Bragg curve(or cell survival fraction was inverse Bragg cueve).(2)Thedynamic change of micronuclei and cell survival inhepatoma SMMC-7721 irradiated by 25MeV/u〓 wasstudied.

采用HeLa、B16两种细胞分别研究了X-射线和重离子在水介质中入射的深度与相应细胞的存活率（1-失活率），结果表明：X-射线对细胞的损伤随深度而逐渐衰减（或细胞存活随深度逐渐增加），而重离子对细胞的损伤则为Bragg曲线（或细胞存活为倒Bragg曲线）。

In 2004, the penetrated depth was increased on each of three expeditions, when a Ukrainian team crossed the 2000-meter mark for the first time in the history of speleology . In October 2005, an unexplored part was found by the CAVEX team, further increasing the known depth of the cave.

而在2004年当一支乌克兰探险队穿过该洞穴2000米深度的标志时，该洞穴探测到的深度在洞穴学历史上第一次被刷新到新的深度。2005年10月，一支名为 CAVEX 的探险队探寻了该洞穴另一处为探明的地方，再次进一步刷新了该洞穴的实际深度。

To analyze the pseudo phenomena caused by migration velocity error, the paper firstly studied the depth error between post-stack migration and prestack migration caused by same velocity error, and found the depth error was only relative to velocity error and had no direct matter with methods of depth migration (post-stack migration or prestack migration). Then the paper did numerical simulation of a complex lenticular body model with wave-equation modeling and migration, and found that the velocity error could not only induce depth error, but also could change the modality of construction and the event of subjacent layers. Furthermore, it could change the frequency of reflective event. They are the pseudo phenomena caused by migration.

从分析偏移速度误差带来的各种假象出发，本文首先对比分析了速度误差对叠后深度偏移和叠前深度偏移的影响，发现偏移剖面的深度误差仅与速度模型的误差有关系，与具体的偏移方法没有直接的关系；然后对一个复杂的透镜体模型进行了波动方程叠后正演和偏移计算，详细地讨论了不同的速度误差带来的各种假象，发现速度误差不仅会带来深度误差，而且会造成构造体的形态变化，下覆地层同向轴的扭曲，还可能引起地层同向轴的频率发生变化，给资料解释带来一定的假象。

When the depth increases, the displacement of wall and the flexural torque value reduce, but the change is small. So if the depth satisfied with soil body hardness and enclosure wall stability, to increase the depth is useless to displacement and flexural torque of wall.(3) Supporting severity.

围护墙的插入深度影响方面，墙的插入深度增加墙体变形和弯弯矩值减小但变化不大，因此当插入深度已经满足土体强度与围护墙的稳定时，再加上深度对墙体变形和弯矩作用影响不大。

This paper presents a rapid inversion method for 3D apparent density based on separation and continuation of potential field. The new method is carried out in the following three steps. Firstly, the gravity field on the plane is separated by a cutting method into several parts corresponding to strata of different depth. Secondly, by the way of downward continuation, the field resulted from different strata is respectively reduced to a plane corresponding to its depth.

文中提出了一种基于位场分离与延拓的视密度快速反演方法：首先应用场分离的切割法对平面上的重力场进行不同深度层源的切割分离；然后运用大深度向下延拓方法将各层的场延拓至相应的深度；最后反演出各深度层的密度。

The wind controls the depth of the upper mixed layer, and its effect could make the mixed layer grow 20～30 m, the short-wave radiation could make the mixed layer shallow 2～3 m and the latent h eat and sensible heat fluxes make the mixed layer become 1～2 m deeper.

风应力对南海混合层深度随时间变化趋势起着决定的作用，并能使其深度加深20～30m，而短波辐射则使混合层的深度变浅2～3m，潜热和感热通量会使混合层的深度加深1～2m。

The results show that the rudder angle of torpedo, the battery activation time, and the initial velocity of torpedo all affect the trajectory of torpedo. The rudder angle ought to be set positive when torpedo is launched downwards,or set negative when torpedo is launched upwards to gain perfect trajectory. Meanwhile, shorter battery activation time and higher initial velocity of torpedo are necessary.

结果表明，以上3个参数对鱼雷弹道都有影响，由小深度向大深度发射鱼雷时，横舵管制舵角应设为正值，由大深度向小深度发射鱼雷时，横舵管制舵角应设为负值，并尽量缩短动力电池激活时间，提高鱼雷出管速度，电动力鱼雷管外激活发射可获得较好的弹道。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
