大功率泵与鼓风机差动调速方案的设计

设计了一种大功率泵与鼓风机的差动调速方案，即由变频器控制的辅助电机的变速运动通过差动变速器与主电机驱动的恒定运动相合成，实现泵与风机的转速调节，此方案可达到显著的节能效果。     

中国航运界关于限制CFCs对策研究

正当近期内，氯氟烃物质（ＣＦＣｓ和ＨＣＦＣｓ）面临着被限制使用或被替代的严峻形势，本文分析了禁用氯氟烃的实质，及其对我国航运界的影响，特别对于远洋运输业的影响。并通过对国内外ＣＦＣｓ替代技术的进展的分析研究，提出我国航运界关于限制ＣＦＣｓ的对策。

流式细胞术检测淋巴细胞亚群的研究

使用流式细胞仪检测了１名传染性单核细胞增多症（ＩＭ）患儿不同病期淋巴细胞亚群的动态变化；１２名肥胖患儿及２０名健康对照儿童的淋巴细胞亚群的比较。检测结果：ＩＭ患儿急性期ＣＤ４＋细胞（４．２％）显著减少，ＣＤ８＋细胞（７２．１％）及ＣＤ８＋ＨＬＡ－ＤＲ＋细胞（６６．２％）显著增加，恢复期及完全恢复后，上述亚群即随之好转至完全正常。肥胖儿童与正常儿童比较：ＣＤ３＋细胞、ＣＤ４＋细胞及ＣＤ４＋／ＣＤ８＋均明显降低，ＣＤ１９＋细胞、ＣＤ５６＋细胞、ＨＬＡ－ＤＲ＋细胞、ＣＤ２５＋细胞均出现有意义的升高。     

Accessing the global seafaring labour market

As a global labour market exists for international shipping, a challenging issue facing this industry is to get access to reliable, accurate and timely information of seafarers’ demand and supply. Related to the deregulation environment and great variety in the availability and quality of relevant information, an enquiry into the global seafaring labour market is more complex than a national labour force survey. To cope with the challenge, a novel approach has been developed by the Seafarers International Research Centre (SIRC) at Cardiff University. Viewing capital (ship), labour (seafarers) and services (cargo or passengers) as interconnected and interwoven to each other, it collects and analyses crew lists from main ports world-wide, resulting in the creation of the first global seafarers database. The purpose of this paper is explain its methodological principles, and to illustrate its application potential. Taking the cruise sector as an example, research findings and methodological implications are highlighted.

BEELE工程用RISE扩展框简化了向RISE系统的转换

由于在安装过程中简易及快速，越来越多的船厂施工人员及建筑部门对电缆导管的防火安全密封装置改用RISE系统。BEELE工程公司位于荷兰Aalten，可提供特殊设计的RISE扩展框，专门设计用简单的方法对现有传统的电缆导管进行升级改进。扩展框横跨导管长度约200mm。扩展框适用于现已安装的电缆导管；它不需拆除原有电缆即可完成安装。     

Development and Evaluation of a High Voltage Supply Unit for Electrorheological Fluid Dampers

Controllable dampers using electrorheological (ER) fluids have attracted considerable interest in recent years. They are proposed for use in semi-active suspensions for ground vehicles. The main advantages of ER fluid dampers are their fast response, ease of control, simple construction and low power requirements. This paper describes the development and testing of a high-voltage supply unit for modulating the damping force of an ER fluid damper. Experimental results on the vibration isolation characteristics of an ER fluid damper with different control strategies, obtained using a quarter-car model test rig, are also presented.
