In this paper, some problems for Large Scale Systems theory are discussed. There are: what the Large Scale System (LSS) is; the relationship between LSS' theory and control theory; the relationship between LSS' theory and System Engineering; the relationship between LSS' theory and Cybernetics; the special problems of LSS' theory. In author's opinion, LSS' theory is the important part of the third age of control theory, i.e. the fundamental of the total complex automation. On the other hand, LSS' theory is...

In this paper, some problems for Large Scale Systems theory are discussed. There are: what the Large Scale System (LSS) is; the relationship between LSS' theory and control theory; the relationship between LSS' theory and System Engineering; the relationship between LSS' theory and Cybernetics; the special problems of LSS' theory. In author's opinion, LSS' theory is the important part of the third age of control theory, i.e. the fundamental of the total complex automation. On the other hand, LSS' theory is the new stage of development Systems Engineering——Dynamical Systems Engineering. It may also be said, LSS' theory is the new branch of cybernetics ——LSS' Cybernetics. LSS' theory is not the classification of the size of various systems, but it's the methodology of the analysis and synthesis of large complex control and information system. It is the system science of large scale systems.

本文讨论关于大系统理论的几个问题,即:什么是大系统?大系统理论与控制理论的关系;大系统理论与系统工程的关系;大系统理论与控制论的关系;大系统理论的特殊问题。作者认为,大系统理论是第三代控制理论的重要内容,是综合自动化的理论基础。另一方面,大系统理论也是系统工程发展的新阶段——动态系统工程。也可以说,大系统理论是控制论的新分支——大系统控制论。大系统理论不是关于系统大小的分类学,而是大规模复杂控制与信息系统分析和综合的方法学,是研究大系统的系统科学。

This paper presents, at first, part of the data on the use of diesel-powered trackless mining equipment in 36 Swedish hardrock underground mines and the threshold limit values of diesel emissions in the underground mine atmosphere, drawn up by the Swedish National Board of Occupational safety and Health. It mentions the large amount of scientific research which has been carried out and is still being studied by designers, manufacturers, mines and research arganizations in order to satisfy these standards. The aims, tasks, fundamental equipment and research methods of diesel exhaust cleaning in the diesel engine laboratory of the University of Lulea are illustrated. It is pointed out that research on purifying diesel exhaust gases should be speeded up for solving the serious mine ventilation problem caused by the use of diesel-powered equipment. The paper concludes that efforts should be made to provide new facilities for efficient ventilation and to develop more modernized trackless mining equipment by increasing research work in the field of automatic ventilation control as well as the design and manufacture of new L H D machines, either diesel-electric-powered or electric-powered with trailing cables. Additional papers in this field of research will follow

文章首先扼要地介绍了瑞典全国三十六个地下金属矿山使用柴油无轨设备的部分统计资料,以及瑞典政府职业安全与健康局关于井下大气中柴油机废气的临界极限标准。指出,为达到这一标准,采掘机械设计制造部门、矿山、科研单位,已经并正在进行大量的研究工作。接着,比较系统地介绍了瑞典律勒欧大学柴油机废气净化实验室的研究任务、目的、基本设备和试验方法。最后,联系柴油无轨设备大量使用所引起的严重的通风问题指出,必须进一步大力开展柴油机废气净化的研究工作。并配合自动通风控制,研究柴油-电力驱动或电缆蒎筒式装运卸机等,将无轨开采技术装备推进到新阶段。

The authors make an all-around and systematic study of the funda mental characteristics of Mesozoic-Cenozoic crustal development in the Changbai-Xingan region on the basis of the results of the previous researches and practical -work according to diwa(geodepression) theory.It is concluded that the crustal movement has been gradually increasing its intensity since the Iate Trias and up to the highest point in the middle-upper Jurassic. Under such geological condition of crustal movement a lot of arched fracture-type and block-type diwa basins were formed. Huge thick Cathysian formations (Molasse strata) with certain terrestrial flysch rhythm were deposited and lots of eruptive rock formations were intercalated in these basins.Great changes took place widely following the strike in these sedimentary formations. One of the chief forms of the crustal movement was the regional fractures which were very active and developed into deep fractures with fault-fold zones distributed widely. In the arched fracture-type and block-type basins there were often formed open bra chyanticlines. Along the deep fracture zones and their adjacent areas the intrusive basic and ultrabasic rocks are widespread. Meta-alkali granite was intruded intensely in fault-fold zones. Magmatism occurred in the sequence from acid to basic-ultrabasic(or alkaline) and abundant mineral deposits were formed.The authors hold that the features of the Mesozoic crustal deve lopment in this region are obviously different from those peculiar to the underlying geosynclinal and platform structral layers. Therefore, a diwa stage indepedent of the platform structural stage should be established, and the region at the present stage must be attributed to diwa regions other than platform ones.

本文根据陈国达教授创立的地洼理论,在前人研究成果及其工作实践的基础上,对长白—兴安地区中新生代地壳发展阶段的基本特征,进行了比较全面系统的研究。认为该区自晚三叠世以来,地壳运动在逐渐增加,直到晚侏罗至早白垩世达到最高潮。在这样地壳运动的地质条件,区内广泛形成有拱曲型和块断型的地洼盆地。在这些盆地中沉积了巨厚层的、具有一定陆相复理式韵律的华夏式建造,并夹杂着大量的火山喷发岩建造。这些沉积建造,普遍的沿走向发生较大的变化。地壳运动的主要形式之一,是区域断裂构造活动强烈,而且形成较为发育的深大断裂构造,断褶带分布广泛。在拱曲型和块断型的地洼盆地中,往往形成开阔的短轴褶皱构造。沿着深大断裂带及其附近,普遍有基性,超基性岩侵入,在断褶带内偏碱性花岗岩浆活动强烈。岩浆侵入活动的顺序,为从酸性岩浆向基性、超基性岩浆(或碱性岩浆)方向演化。并形成有丰富的矿产。 笔者认为该区中新生代地壳发展的特点,与下伏基底地槽和地台构造层所代表的发展阶段的特点具有明显区别。因此,应当将它从区内由地台构造层代表的发展阶段划分出来;它是,一个新的阶段——地洼发展阶段。其现阶段的区域大地构造性质,不应当归入地台区,而是属于地洼区。
