人工气候条件下的人体着装试验的研究

本文通过物理试验方法对棉、毛、丝、棉麻及毛涤五种面料进行性能测试,得出其风格数值、透湿阻抗.为了反映面料对人的生理、心理的影响,有必要在人工气候条件下进行人体模拟着装试验,得出面料的人体舒适感觉值。借助多元线性回归方法,通过物理测试与人体试验的对照分析,发现它们之间具有良好的一致性。

Modeling and Control of Active Suspensions for MDOF Vehicle

The conventional method for analyzing active suspension control for a vehicle is only to analyze a quarter or half car with a lower order degree-of-freedom (DOF) model, but such models do not actually model practical applications. Accurate models of a suspension control system require a multi-degree-of-freedom (MDOF) vehicle model with a detailed model of the controller. An MDOF model was developed including the influence of factors such as the engine, the seats, and the passengers to describe vehicle motion using a reduced order model of the controller designed by using the H∞ control method. The control system performance has been investigated by comparing the H∞controller with a linear quadratic (LQ) controller.     

中国西部城镇化发展的“三分”构想

在经济全球一体化和经济区域化已成为当今世界经济发展大势的背景下，西部区域经济之所以发展不利，根本原因是区域经济理论陈旧落后，缺乏创新的区域发展思维。这些深层次的问题得不到解决，西部的城镇化水平和区域经济难以得到快速发展。因此，“三分构想”的提出是十分必要和迫切的。

SQL多表外连接查询

介绍了外连接查询的意义、外连接查询的实现步骤和方法，着重指出：SQL对一父多子的多个表进行外连接查询时，要特别注意FROM子句中连接对象和连接条件的先后位置。当子表中符合连接条件的记录有多条时，不要在SQL—SELECT语句中用SUMO函数和GROUP BY子句实现分组汇总，应汇总后再连接。否则，会导致汇总数据的错误，并且执行时间也大大增加。需对结果中值为NUIL的字段进行数学运算时。要对其进行替换处理。     

OPTIMAL SETTING-UP OF KNITTING ELEMENTS AND ITS EFFECT ON TENSION VARIATION

The dynamic yarn tension variations during knitting cycle are very difficult to control and be-come one of barriers to knitting on modern warp knitting machine.Examination of experimentaldata and theoretical analysis show that the relative position of spring rail to knitting elements suchas needle,guide as well as their displacement has noticeable effect on tension variation so that theknitting condition can be much improved by rearrangement of the knitting elements and theirmovement within a knitting cycle.
