Method of prediction of earthquake by using seismisity

The method of prediction of earthquake by using seismisity (MPES) is to make use of the message of earthquakes (including large, middle, small) in pre-period to predict large earthquake in post-period. Some better methods are presented in this paper which are selected among many means used in our country recent years. These methods are classified into six sets: 1. Method of spatial pattern; 2. Method of time process; 3. Method of seismic sequence; 4. Method of earthquake correlation; 5. Method of parameters of seismic source and medium; 6. Comprehensive method. Prediction effects of each method are evaluated with unique score. The value of each method, scoreR, are generally in a range between 0.3 and 0.6. This value only represents internal consistency, however, the ability of actual prediction belongs to the extensional effect, which is generally lower than the value of internal consistency. If the ability of actual prediction could be evaluated withR = 0.3, the ability of prediction of earthquake by seismicity will be stated as following: If most of earthquakes must be predicted, the warning time needs to take seventy percent of whole time period of prediction; If half earthquakes must be predicted, the warning time needs to take twenty percent of whole time period of prediction. The Chinese version of this paper appeared in the Chinese edition ofActa Seismologica Sinica,15, 239–252, 1993.     

土的工程力学性质与其电阻率关系实验研究

建立岩土的工程力学性质与其地球物理参数的量化关系是实现工程物探资料量化解释的必然前提。本次工作在分析影响土的工程力学性质和电阻率的共同因素基础上，通过室内实验，研究了不同类型土的粒度成分、含水率、饱和度、密实度与其电阻率的关系，并在此基础上探讨了耗土的压缩系数、粘聚力、压缩模量与电阻率的关系，得出了一系列的关系曲线及一些拟合公式，并对这些公式的含义进行了解释。

Disaggregation modelling of monthly streamflows using a new approach of the method of fragments

Abstract

The method of fragments is applied to the generation of synthetic monthly streamflow series using streamflow data from 34 gauging stations in mainland Portugal. A generation model based on the random sampling of the log-Pearson Type III distribution was applied to each sample to generate 1200 synthetic series of annual streamflow with an equal length to that of the sample. The synthetic annual streamflow series were then disaggregated into monthly streamflows using the method of fragments, by three approaches that differed in terms of the establishment of classes and the selection of fragments. The results of the application of such approaches were compared in terms of the capacity of the method to preserve the main monthly statistical parameters of the historical samples.

The equation of motion for a small aerosol in a continuum

Summary The motion of an aerosol can be described by a general force balance equation, independent of the detailed structure of the flow, provided that the interaction between the external flow field and the local flow induced by the aerosol is weak. A necessary and sufficient condition for the interaction to be weak is that the length scale of the aerosol is much less than that of the external flow. High and low Reynolds number regimes can be distinguished for the motion of an aerosol relative to the external flow. In some extreme conditions the equation of motion reduces to an algebraic equation for the aerosol velocity.After submission of this article the author was made aware of a similar treatment published inTopics of Appl. Phys., 12 (Turbulence, Chapter 7), Springer Verlag, Berlin, which at the time of the article's submission had not yet appeared in Australia. (Ed.)
