查询词典 Maximum Velocity

The SSTA of February and August in 1998 had two peaks, while the wind speed reached its maximum minus anomalies in January and August. In order to find the circulation anomaly in the South China Sea, the circulation of 19952000 had been calculated by the ECOM hydrodynamic numerical model. The elevation and circulation of January and August in 1998 indicated that there were great anomaly of elevation and circulation after this El Nio event.(1)In January, the whole South China Sea had positive sea level anomaly and anticyclonic velocity anomaly, so the cyclonic circulation was weaker than normal.(2) In August, the South China Sea had positive sea level anomaly, especially stronger in the east of Vietnam, and cyclonic velocity anomaly in south, anticyclonic velocity in north, especially strong in the east of Vietnam. So the cyclonic gyre in the north and the anticyclonic gyre in the south were both weaker than normal, and an anticyclonic gyre appeared in the east of Vietnam.

为研究南海环流在1997/1998年的异常变化，利用ECOM水动力模型计算了1995—2000年的南海环流场，分析了1998年1月和8月南海水位和环流的异常分布，二者均存在显著的异常：①1月，整个南海海盆为正的水位异常，流场为反气旋异常环流，冬季控制整个南海海盆的气旋式环流减弱；②8月，南海海盆水位为正异常，特别是越南东部海区出现较强的正水位异常，南海南部的高水位中心扩大北移；异常流场表现为南部为气旋式异常环流，北部为反气旋的异常环流，且在越南东部海区形成非常强的反气旋异常环流中心，使得控制南海南部的反气旋环流和北部的气旋环流均减弱。

The soil urease and invertase activity effected by Hg was investigated in different fertility soils. The results show that soil urease activity、maximum reaction velocity (Vmax、Vmax/Km) and reaction velocity constant k have remarkably negative correlation with Hg concentration so that these can be used as ecological indexes of soil polluted by Hg, Km changes a little indicating that the reaction mechanism of Hg and urease is nonreversible competitive restraint. Urease of low soil fertility is more damaged by Hg than that of high soil fertility, with severe pollution at Hg concentration of 6.00 and 14.79mg/kg respectively; while invertase is less sensitive to Hg than urease. Cultural time has less influence on the relationship of soil enzyme and Hg concentration.

对不同肥力土壤脲酶和转化酶活性受汞影响进行了研究，结果显示，土壤脲酶活性、最大反应速度Vmax 、Vmax/Km和反应速度常数k与汞浓度呈现显著或极显著负相关关系，表明其可作为土壤汞污染的生态指标；米氏常数Km则变化较小，表明汞与脲酶作用机理为不可逆竞争抑制；低肥力土壤脲酶比高肥力土壤脲酶受汞毒害作用更强，当汞浓度分别为6.00和14.79mg/kg时即达到严重污染；而转化酶对汞的敏感性较差；培养时间对土壤酶与汞浓度间关系影响较小。

Through S-wave polarization scanning mode of ultrasonic impulse testing, rock samples with three different properties are measured to evaluate the variation of S-wave velocity in three perpendicular coordinates. By analyzing S-wave splitting of three directions and polarization of the maximum or minimum speed S-wave amplitudes, we think that the velocity orthotropy and fracture orientation observed in the grain sandstones and crack marble samples can be estimated in terms of the polarization and velocity of S-wave. Also, perpendicularity characteristics on the two types of rocks can attribute to the bedding and structure of rocks (directional grains or crystallize).

在实验室通过选择了三种不同岩性的岩石，采用超声脉冲测试方法中的横波偏振扫描方式，观测了岩石样品三个坐标方向上的横波速度变化，通过分析三个传播方向上出现横波分裂的差异，以及出现最大或最小快慢横波振幅的偏振方向发现，可从横波偏振方向和速度值判断出纹理砂岩和裂隙大理岩样品存在不同程度的速度正交各向异性和裂隙方向等特征，认为这两种岩石的正交特性的原因是岩石的层理或裂隙与岩石本身的结构构成的。

It is recommendable, particularly, to incorporate the fluid viscous dampers into this structure that contain weak story to refrain earthquake and reinforce, such as the Central Hall of Shanghai Exhibition Hall.

首先使用了反应谱分析法设计出欲附设的粘滞阻尼器的线性阻尼系数，由于实际工程所用的粘滞阻尼器具有非线性的特性，故而笔者又证明了降低速度指数对提高粘滞阻尼器的耗能量的优势所在；接着分别从位移、层间位移、速度、层间速度、加速度、能量、最大阻尼出力和柱轴力等不同的角度对结构在附设粘滞阻尼器前后的时程反应进行了分析对比，籍此在实际工程中证明了附设粘滞阻尼器对于提高结构的抗震性能的优越性；再者，笔者还阐述了采用不同的粘滞阻尼器布置方式对结构中构件内力特别是柱轴力和基座竖向反力产生的不利影响，并在此基础上提出了布置方式的优选；最后，指出了反应谱法在设计中的适用范围：对于均匀结构反应谱法能够使用，而对于含有薄弱层的结构反应谱法并不适用；对于类似于上海展览馆中央大厅的含薄弱层的结构尤其值得使用粘滞阻尼器的方法进行抗震加固。

Using harmonic analysis of the calculated tidal level and current, the distributions of co-tidal lines for K1, O1, M2 and S2 are obtained, whose maximum amplitudes can reach 112 cm, 96 cm, 50 cm and 15 cm, respectively. The distribution of the maximum probable current velocities in Qinzhou Bay is basically the same as that of isobaths, and the maximum probable current velocity can reach 200cms^(-1) nearby the Longmen Harbor. It is concluded by the analysis of K1 and M2 tidal current ellipses that the flow is rotating at the mouth of the bay, while its retilinear flow is in the nearshore area, estuaries and channels. The distributions of the major axes are closely related to the topography, and the rotation directions of both constituents are clockwise.
