In this paper are reported results of experimental invertigation of electromagnetic and optical radiations produced by single bubble cavitation. After observation and brief theoretical analysis of growth and collapse of single bubble, these radiations were studied experimentally. The pre-sense of electromagnetic radiation was confirmed.

In this paper are reported results of experimental invertigation of electromagnetic and optical radiations produced by single bubble cavitation. After observation and brief theoretical analysis of growth and collapse of single bubble, these radiations were studied experimentally. The pre-sense of electromagnetic radiation was confirmed. In contrast with the statistical conclusion drawn by other workers for optical radiation, generations of optical and electromagnetic radiations are found to be simultaneous at the moment of bubble collapse. Then the effects of varying liquids and gases and of varying speeds of bubble collapse on electromagnetic and optical radiations were inverstigated. Experimental results show that, although electromagnetic radiation as well as optical radiation occur as predicted by Frenkel, the mechanism cannot be explained by his hypothisis. It is considered that generation of these radiations may be related to the generation of micro-shock wave in the bubble at the moment of its collapse.

本文报导关于单一气泡空化所产生电磁辐射和光辐射的实验研究.在观察和简略理论分析单一空化气泡的生长和闭合运动后,用实验方法研究了这两种辐射.首先肯定了电磁辐射的存在;并与其他一些有关光辐射的工作所作统计性的结论有别,明确肯定电磁辐射和光辐射同时发生在气泡闭合时刻.接着研究了几种液体、几种气体以及气泡闭合速度对两种辐射的影响.实验结果表明,虽然存在有Frenkel所预言的电磁辐射和光辐射,但其机制不是他提出的假说.初步看来,两种辐射的产生可能与闭合时气泡中所产生的微骇波有关.

The chief points of this method are the applications of the theory of random time-varying networks and the theory of streams of random events in queueing theory. An expression of space-time correlation function of scattered fields is established by this method.

A method for finding the statistical properties of scattered fields caused by scatterers is established. The chief points of this method are the applications of the theory of random time-varying networks and the theory of streams of random events in queueing theory. An expression of space-time correlation function of scattered fields is established by this method. More factors, such as the random motions of scatterers, the statistical dependence between these motions, the inhomogeneities (including stratified inhomogeneity) of propagation medium, the dispersion and absorption by the medium, the differences between scatterers, and the like, are taken into account in this expression. These factors are always unnegligible in most practical problems. Moreover, the functional forms of transmitted signals, directivity of radiation, spatial distribution of scatterers, scattering coefficients, etc. are unrestricted in this expression.As an example, the statistical properties of back scattering of underwater sound by the bubbles, the random motions of which are caused by the waves, are studied.

本文提出了一种寻求散射体羣的散射场的统计性质的方法.该法要点在于运用随机时变网络理论及排队论中关于随机事件流的理论.借助于此法,本文建立了散射场的空间-时间相关函数的表示式.与其他作者已建立的公式相较,该式计及一系列常为实际问题所不容忽略的因素,例如诸散射体的随机变速运动及其间的统计关联,传播媒质的非均匀性(包括分层非均匀性)、吸收及色散,以及诸散射体性质的相异性等等,并且对发射信号、辐射方向性、散射体羣的空间分布及散射系数等等的函数形式均未给予任何限制.

Using the 24-litre propane chamber, photographs from JINR π0-meson production in inelastic interactions of π--mesons of momentum 6.8 GeV/c with nucleons are examined. About 2700 pairs of stereoscopic pictures have been scanned and 1275 events of π--N inelastic interactions have been found in an effective region 29.3 cm wide. In these events, 936 π--p and 339 π--n events, 240 and 89 electron-positron pairs have been observed respectively. After taking account of the efficiency of the bubble chamber for...

Using the 24-litre propane chamber, photographs from JINR π0-meson production in inelastic interactions of π--mesons of momentum 6.8 GeV/c with nucleons are examined. About 2700 pairs of stereoscopic pictures have been scanned and 1275 events of π--N inelastic interactions have been found in an effective region 29.3 cm wide. In these events, 936 π--p and 339 π--n events, 240 and 89 electron-positron pairs have been observed respectively. After taking account of the efficiency of the bubble chamber for detection of γ-photons, it is found that the mean number of π0 mesons produced per event is nπ0 = 1.00 ?0.06 and the mean transverse momentum of the r-photons is Pγ⊥ = 173 MeV/c. In addition, the energy distribution of the γ-photons is especially examined. Under the assumptions that the γ-photons are entirely due to π0 decays and that the energy spectrum of the π0 mesons is the same as that of the π± -mesons', an energy distribution of γ-photons can be deduced from the energy distribution of the secondary π±-mesons produced in π--N interactions at the same incident energy[1,2]; the γ-photon energy distribution obtained in the present experiment is in agreement with this deduced distribution within experimental error.

利用联合原子核研究所24立升丙烷气泡室照片,对动量为6.8GeV/cπ~- 介子与核子非弹性作用产生π~0介子的问题进行了研究。扫描了约2700对立体照片。在宽度为29.3厘米的有效范围内得到了1275个π~--N非弹性作用事例。在936个π~--p事例和339个π~--n事例中,观察到正电子、负电子对数目分别为240和89。考虑了气泡室对γ光子的探测效率,我们得到每个事例产生的平均π~0介子数_π~0=1.00±0.06。γ光子的平均横动量为_⊥γ=173MeV/c。此外,着重研究了γ光子的能量分布。在γ光子全部是由π~0介子衰变产生以及π~0介子和π~±介子具有相同能谱的假设下,利用在相同入射粒子能量的π~--N作用中所产生的次级π~±介子能量分布变换成γ光子的能量分布;将本实验所得的γ光子能量分布和变换得到的分布进行比较,这两个分布在实验误差范围内完全符合。
