Let (X,A,p) be a complete probability space. A function f: X is called premeasurable, if there is a measure extension of p defined on the -algebra generated byA and the function f. Several classes of premeasurable functions are studied here. This paper is a continuation of Bierlein's investigations in [2], [3] and [4]. The basic ideas and notations can be found there. 相似文献

In this paper we shall establish the notion of compatibility between preorderings and places for planar ternary rings. The theorem of Baer and Krull concerning the relationship between the orderings of a field K, compatible with a place : KK {}, and the space of orderings of K is extended to ternary rings. We study the notion of fans and SAP-preorderings over ternary rings and prove that no Archimedean ordering contains a non-trivial fan. Finally the local stability formula of Bröcker is carried over to ternary rings. 相似文献

Summary A versatile pulse counter arrangement for nuclear radiation measurements is described. It consists of ten binary scalers (one E90CC tube per channel, deadtime 1·5 s), ten commercial decade plug-in units (one E1T+E90CC, deadtime 27 s), and ten mechanical registers (driven by one E90CC, 20 counts/s). The binary scalers accept negative pulses (10 V, rise <0·5 s, decay >1 s) and serve as fast input scaling stages; they are designed to produce output pulses of the special shape required for triggering the subsequent decade stages.If all decade units are used singly, this equipment permits to count pulses in ten independent channels at a maximum rate of 400/s with negligible losses. On the other hand, one or several decade pairs can be made to work as scale-of-200's, so that up to 4000 pulses/s/channel can be measured with counting losses 1%.In cases where only 5 independent channels are needed, a switch common to all channels eliminates the dead-time otherwise required for reading out the counting results. This is done by alternative switching between even and odd registers, and in those channels which are connected as scale-of-20's, also the corresponding decade units are stopped and can be read whilst the other group of channels is working. This feature has proved especially helpful in investigations on the scintillation spectra of short-lived radioisotopes.The power supply has been constructed without using an anode voltage transformer, so that the whole apparatus is small and relatively light weighted. 相似文献
