This paper presents a meteor burst communication network developed for auto hydrological and meteorological data acquisition from outlying districts. The internal structure of the net is designed according to the spatial properties of meteor trails. A new protocol together with Subgroup Polling, AU Remotes Answering and Polling Remote by Remote are proposed to increase communication efficiency. Also, the paper extends the concepts, such as the Average Waiting Time which is used to evaluate the system performances, from point-to-point mode to network mode. The results of computations and analysis show that the performance of the system designed here is better than that of the SNOTEL system .

The accuracy of neutral track measurement by Barrel Shower Counter (BSC)at BES is inveshgated. The photon energy in BSC is corrected using radiative Bhabhaevents and the error is determined. The error of photon position in BSC is alsodetermined using the e+ e- process. All these results can be applied to BESanalysis including neutral tracks, and the systematic error can be remarkably reducedwhen the kinematic fit is adopted.

The beam emittance and brightness are the important figure of merit for the beam in accelerator. According to the theory of beam phase space, the projective density distributions in four dimensional and two dimensional trace space are derived for some space charge distributions often used in accelerator physics. And, the relation between beam emittance and brightness with density distributions is developed too.

束流发射度和束流亮度是表征加速器束流品质的主要指标。理论和实验研究都已发现,它们与束流空间电荷的非均匀分布有密切关系。针对加速器中几种常用的束流密度相空间分布形式,根据束流相空间理论,推得了它们在四维和二维径迹空间中的投影密度,并给出了束流发射度和亮度与束流密度分布的关系式,为加速器束流测量和束流诊断提供理论依据。
