 In the field of post and communication, the papers about appli cation of the theory of quality control are seldom seen. This paper discusse the problem of application of quality control, especially the control chart in the field of post and communication. Due to fluctuations of the quantity of demand, in applying control chart, we must do regression analysis of the quality index and the quantity of demand. If the regression is significant, then we must use the selecting control charts proposed by the author.... In the field of post and communication, the papers about appli cation of the theory of quality control are seldom seen. This paper discusse the problem of application of quality control, especially the control chart in the field of post and communication. Due to fluctuations of the quantity of demand, in applying control chart, we must do regression analysis of the quality index and the quantity of demand. If the regression is significant, then we must use the selecting control charts proposed by the author. Otherwise, the Shewhart's control charts can be used. From the viewpoint of the theory of queue, the system of post and comnun ication is a system of queue. Hence, the problem that the quality index and the quantity of demand is correlated or not, under the given conditions and within certain limit of the quantity of demand, depend on the characteristics of the system of queue. If the system is of random arrival and service in batch, then it is not correlated in general; if the sgstem is of random arrival and service in order (including the case with priority), then it is correlated in general. The theory presented in this paper has succeeded in the control of overlimit rate and register return rate of longdistance telephone, and begin to be used in Peking, Shenyang and Hupei etc, According to the statistical data in practice, the accuracy of allarm of this selecting control chart is about ten times higher than the Shewhart's control chart. As to the maintenance, this paper lays stress on the importance of correctve maintenance that is cortrolled by the method of quality control. At the end of this paper, it is pointed out that the feature of the industry of post and communication is "more variety, less quantity". Hence it is effective to apply unitedly the same control chart for different cases, provided that the com mon points in production is grasped. In this paper, many practical examples solved by the author are also included which may be of use to the reader for reference.  在国内外文献中,关于质量控制在邮电部门中的应用很少见。本文专门论述了质量控制,尤其是控制图在邮电各个部门中应用的问题,希望对于我国邮电部门当前推广应用质量控制有所裨益。在邮电通信部门,由于邮电业务量波动的影响,所以在应用控制图时,需要对质量指标和业务量进行相关分析,若有显著相关,则必须采用作者所提出的选控控制图,否则可用休哈特(W.A.Shewhart)控制图。从运筹学排队论来看,邮电通信部门是个排队系统。因此,被控制质量指标与通信业务量是否相关这个问题,在现有的人员设备条件下,在一定的业务量范围内,主要决定于排队系统的特性。若排队系统为随机到达、成批服务,则一般不相关:若排队系统为随机到达、按序服务(包括具有优先权的情况在内)则一般相关。选控控制图已在控制长话逾限率和退号率等方面获得成功,根据北京、沈阳、湖北郧阳等地使用结果证实,选控控制图发现问题的准确度要比Shewhart控制图高十倍左右。在邮电维护方面,本文强调了引进质量控制方法的受控纠正性维护方式的重要性。本文最后指出,邮电工业的特点是“多种少量”,因而抓住加工或生产中的共同点,统一应用控制图是有效的措施。本文附有若干应用实例,大多是作者所解决的实际... 在国内外文献中,关于质量控制在邮电部门中的应用很少见。本文专门论述了质量控制,尤其是控制图在邮电各个部门中应用的问题,希望对于我国邮电部门当前推广应用质量控制有所裨益。在邮电通信部门,由于邮电业务量波动的影响,所以在应用控制图时,需要对质量指标和业务量进行相关分析,若有显著相关,则必须采用作者所提出的选控控制图,否则可用休哈特(W.A.Shewhart)控制图。从运筹学排队论来看,邮电通信部门是个排队系统。因此,被控制质量指标与通信业务量是否相关这个问题,在现有的人员设备条件下,在一定的业务量范围内,主要决定于排队系统的特性。若排队系统为随机到达、成批服务,则一般不相关:若排队系统为随机到达、按序服务(包括具有优先权的情况在内)则一般相关。选控控制图已在控制长话逾限率和退号率等方面获得成功,根据北京、沈阳、湖北郧阳等地使用结果证实,选控控制图发现问题的准确度要比Shewhart控制图高十倍左右。在邮电维护方面,本文强调了引进质量控制方法的受控纠正性维护方式的重要性。本文最后指出,邮电工业的特点是“多种少量”,因而抓住加工或生产中的共同点,统一应用控制图是有效的措施。本文附有若干应用实例,大多是作者所解决的实际问题,可供参考。  We have compared the Haicheng foreshock sequence with several earthquake swarms occurred in its neighborhood. Their spatial distribution of earthquakes was relatively concentrated. For the most part, the events occurred within a few kilometers from each other. The focal mechanisms are comparatively stable. However, there are several swarms in which the variations of focal mechanisms are quite obvious after the occurrence of the largest event of the sequence which would allow it to be recognized as a swarm.

For the most part, the events occurred within a few kilometers from each other. The focal mechanisms are comparatively stable. However, there are several swarms in which the variations of focal mechanisms are quite obvious after the occurrence of the largest event of the sequence which would allow it to be recognized as a swarm. However, there are also swarms whose focal mechanisms are no less stable throughout the sequence as compared with that of the Haicheng foreshock sequence. So this feature could not be used to identify foreshock sequence. The temporal distributions of foreshocks and swarms are quite similar in some cases. This is again not a definite criterion for discriminating foreshocks and is only within our present ability, but is worthy of further study. Thus in general, no definite criterion for identifying foreshock sequence has been found. Only for some earthquake swarms may be recognized in their later stage.Finally, we introduced a magnitude sequence with gaps which, may be used whether a large event is still forthcoming. This method (in conjunction with other methods) could be of use in areas prone to large earthquakes immediately before a large event to improve determining the probability of a large event occurring. We also note that the temporal distribution of all the sequences showed a 12 hour recurrence pattern that corresponded with the earth tides, showing that tidal forces might be influencing foreshocks and earthquake swarm occurrence.  对比了海城前震系列与其周围同期震群的异同.两者的震源空间分布都比较集中,一般只有几公里的尺度.发震机制都比较稳定.但有些震群在其主要地震发生后,机制变化较显著,借此有可能识别一部份震群.但也有些震群其机制的稳定性始终不比海城前震系列差,因之借此无法识别前震系列.频次的分布两者也有非常相似的震例.总的印象是有些震群在晚期有可能识别,但未发现有确认前震(系列)的肯定判据.这一初步的结论仅仅是由于我们分辨技术的局限,抑是具有成因上的深刻含义是很值得思考的.最后引入了震级序列的缺震特征,借此可以判断系列的高潮是否已经渡过.这对(从其他证据认识到的)具有大震危险的地区,利用前震系列来改善大震临震时刻的机率性判断是有用的.注意到频次分布中有相隔12小时的低值点,对比就地的固体潮具有较好的同步性,说明固体潮可能对前震系列以及震群具有触发作用.  In this part, the third order radial ion trajectory and the second order axial ion trajectory for a crossed toroidal electric and inhomogeneous magnetic field are studied. The formulae for the third order trajectory and slope are derived, which cover most cases of sector fields and in special cases agree with those already presented by previous authors. Therefore, these results are general and may be of use in designing mass spectrometers. The effects of oblique entrance and exit, curved field boundary...
