Near-field records of two strong aftershocks with magnitudeM
S=6.7 andM
S=6.3 in the Lancang-Gengma earthquakes sequence, Yunnan Province, November 1988, are used to calculate the response spectrum.
The instruments, site conditions and the methods for computing are also illustrated in this paper.

Based on Generalized Seismic Ray Theory (Helmberger, 1968), a new quickly linear inversion method from the data of seismic
waveform to seismic moment tensor and source mechanism for domestic earthquake is studied in this paper. Six moderately strong
earthquakes which occurred in Chinese mainland in the past few years are studied. The seismic source parameters of these earthquakes,
seismic moment tensors, scalar seismic moments, fault plane solutions and source time functionsetc, are obtained.

In this paper, the coefficients of Parkinson vectora, b and the in-phase partA
r, Br and quadrature-phase partA
i, Bi of transter functions are calculated by using two kinds of data processing methods, respectively. The results of both methods
are close to each other. All these six parameters above are low in value, showing that the electric structure in Heze area
is rather uniform. It seems that the anomalous changes appeared in both results, and the values of parameters decrease before
and after Heze earthquake.

This paper summarizes the origin and idea of the control of civil engineering structures and reviews the state-of-the art
of recent advances in structural control both theoretically and technologically. The prospects for structural control and
key research objects to remain to be solved are put forward at last.

In this paper we investigate the sources of two kinds of forces to form the stress field in the lithosphere. These are the
drag force caused by mantle flow and the force system along plate boundaries. The results show that both forces control the
basic stress pattern in China and compressive stresses can fit with the stress patterns constructed by focal mechanisms,in-situ stress measurements in boreholes and that deduced from other geophysical and geological observation.

The Zaisang earthquake (M
s=7.3) on June 14, 1990 occurred in the boundary between China and Kazakstan. During the great shock, 3 persons lost their
lives, 30 people had been hurt and 340 houses collapsed. The intensity of the epicentre is VIII Degree. The economic losses
equals to about 320 000 000 Yuan. This large earthquake was occurred on a new born fault, it belongs to main shock-aftershock
type earthquake.

The neotectonic stress field in Chao-Shan area is analyzed with the fault striation analysis method. At least four types of
stress states are detected, which are in close connection with their locations relative to the basin. Generally, from the
subsidence centres to places far from them, horizontal tectonic stress varies from tensile to compressive.

The influence of the four different methods of measuring Lg amplitude, and the selection of different geometrical attenuation
coefficient ζ-values (=5/6 or 1) on the determination ofγ value of Lg wave are discussed.γ=0.0034±0.0001km−1 (when ζ=5/6) for six eastern provinces is redetermined. The revised magnitude calibration function ofm
Lg (mxh),q
E (Δ)=(5/6)logΔ+0.00147Δ+1.81 is deduced.

We have employed 10 digital records and computed the spectral magnitude and the seismic radiated energy for 18 large earthquakes
(M
s≥6) occurred in Eur-asian belt during 1986–1989. The nine digital stations (CD-SN) distribute all over China and one in Germany.
The spectral magnitudes of various period have different stability among stations. The stability is better for maximum spectral
magnitudemi and seismic radiated energyE, their differences among stations are smaller, especially for the stations where the ray path main penetrates the low mantle.
But the stability of corner period is usually not good. The relation between seismic radiated energy and seismic moment magnitudeM
w is lg (E)=1.5Mw+c, wherec is a constant. The maximum spectral magnitudemi=M
w+0.1, it is consistant with theoretical prediction.

The parameters of rocks in ultrahigh-presure state are very important to understanding the geodynamics and explosion engineering
of rocks. In these experiments the plane wave dynamite lenses were used to drive the flying plates. The flying plate hits
the target and produces the ultrahigh-pressure shock wave. The propagation velocity and the particle velocity of shock wave
in rock samples were measured by probes, and the relation between density of rocks and pressure was obtained by Rankine-Hugoniot
formulas. The maximum pressure in experiments was higher than 70 GPa. The ultrahigh-pressure state formulas obtained are:
Limestoneρ=3.22+0.016p; Graniteρ=3.20+0.024p. In which the unit for ρ is g/cm3, the unit forp is GPa.

This paper presents the analytic result on the correlation between the high energy charged particle flux in the radiation
belt around the earth and the earthquake activities. It points out that the increment of count-speed of high energy charged
particle flux in the upper atmosphere has definite relationship with the intensity of seismic activities on the earth.
