混合岩中脉体是多成因的,如何区分脉体的成因是研究混合岩的一个关键问题。脉体中矿物在空间的分布特征是区分不同成因脉体的标志之一。利用线切法或接触—频效法进行接触类型的统计,在此基础上求出随机分布条件下的期望接触频数。某种接触类型实测出现的数目与期望接触频数之比定义为R。R值反映出矿物在岩石中的空间分布特征与随机分市特征的偏离程度。同类接触中R<1为规则分布;R=1为随机分布;R>1为集聚分布。不同成因的脉体其R值有较大差异,当脉体为注入或深熔作用的产物时,脉体中的矿物在空间上呈随机分布,R值为1或接近于1;当为变质分异或交代作用的产物时,脉体中的矿物在空间上不呈随机分布,而为集聚分布或规则分布,R值显著大于或小于1。以此可以区分不同脉体的成因。

A quantitative study on human water contact was carried out in an endemic area of schistosomiasis japonica. The information relating to frequency, duration and intensity of each activities was obtained from 390 persons (93% of all) aged 5-59 and 10 days of each season in 1987 was surveyed by using systematic sampling. Socioeconomic investigation and stool examination were also performed on the same population. It is found that cutting grass and fishing are the most important activities, as well as swimming and bathing. The accumulated index ofexposure is high in spring and summer, low in autumn and rare in winter. The peak contact is 8-12 o'clock in the morning. The reasons of contact are different between males and females. And the peak contact is at teen aged youth. Studies on water contact and socioeconomic factors show that there are more contacts in peasants than in those with other occupations. Rich farmers who has more savings contact less. The contacts seem more frequent in those whose family water supply is from infected water. The stepwise regression analysis shows that the most important factor relating to the infection of schistosomiasis japonica are index B of exposure (accumulation of duration × intensity). The infected water supply of family and education were two other factors relating to the infection.

1987年,在湖滩型日本血吸虫病流行区,对390名(占总人口93%)居民接触疫水行为进行了随机抽样每季度10d的调查,内容包括接触的频数及每次的类型、持续时间、强度、时间及离居民点距离。并对同一人群进行了社会经济情况调查及粪便血吸虫虫卵检查。结果发现:打草、抓鱼虾是最主要的接触类型,其次是游泳洗澡。接触以春夏较多,秋季次之冬季最少。接触疫水的年龄高峰在10~19岁而时间高峰在上午8~12点。女性的接触频数及持续时间显著高于男性,但累计强度并无显著差别。二性的接触类型很不一致。疫水接触与社会经济因素的研究发现农民接触多于其它职业,生活用水来源于疫水者接触疫水频数高,家中积蓄多者接触疫水少。逐步回归的结果表明:接触疫水是感染血吸虫病最重要因素。另外,生活用水来源及文化程度也与感染显著有关。

A description and analysis of constraints are given for the ideal case where the end-effector of a single robot manipulator is in contact with rigid environments. After this,control variables are decomposed into two parts,each of which belongs to one of two mutually vertical and complementary subspaces,respectively,such that the dynamic equations of the robot arm can be split into two corresponding groups:one is...

A hybrid control strategy for a class of compliant motions of robot manipulators is investigated. A description and analysis of constraints are given for the ideal case where the end-effector of a single robot manipulator is in contact with rigid environments. After this,control variables are decomposed into two parts,each of which belongs to one of two mutually vertical and complementary subspaces,respectively,such that the dynamic equations of the robot arm can be split into two corresponding groups:one is used for force control and the other for motion control. Consequently, the idea behind the hybrid control strategy is revealed. As a result,the design of hybrid control laws can be carried out in a simple way,i. e. force controller and motion controller can be separately designed.

本文研究了理想情形下一类机器人适从运动的混合控制。对于一个机械臂手端与刚性环境发生光滑接触的类型,本文给出了一种约束描述,并进行分析。在此基础上,通过将控制变量分成两个分属于相互垂直的子空间的控制:力控制和运动控制,将机械臂动力学方程分裂成两个。一个用于力控制,另一个用于运动控制。从而对混合控制的思想有了更好的理解,使力控制和运动控制的设计能单独分别进行,为寻找混合控制提供了简便途径。
