Present Tectonic Stress Field in the Capital Region of China Inverted from Focal Mechanisms of Small and Strong Earthquakes

A dense seismic network was installed in the capital region of China in recent years,which makes it possible to resolve the focal mechanisms of small earthquakes. We gathered large earthquake focal mechanisms from the last fifty years and moderate or small earthquake focal mechanisms from between 2002 and 2004,and calculated the present tectonic stress field of the capital region by the grid search method, which weighs different sized earthquakes and can improve the accuracy of the stress field inversion. The analysis of inversion results of different sub-regions shows that the azinuth of the maximum principal compressive stress axis is NE43°- 86° in the Beijing-Zhangjiakou-Datong area,NE38°-86° in the Tangshan area,and NE79°- 81° in the Xingtai area. Inversion results of this paper are similar to previous results,which proves the correctness of the approach. As revealed by the results,the stress field of the capital region is characterized by overall consistency and sub-regional differences. This study provides reference for earthquake mechanism explanation and geodynamics research.

The Capital Iron and Steel Corporation's Fast Development of Exposer Trade

The Capital Iron and Steel Corporation (Shou Gang) is one of the eight major iron and steel companies in China and one of the first state-owned enterprises to be selected as a testing ground for the reform programme, since it was authorized to manage its own foreign trade in 1981, the Corporation’s export trade has expanded steadily. Especially since 1992, its development in foreign trade has skyrocketed because China Shou Gang International Trade Construction Company was approved to be set up. In 1993, it exported 239,700 tons of steel. Its foreign exchange income reached US$630 million, of which the Shou Gang’s self-managed exports took up US$96.98 million. During the

The supervision of the pension funds entering the capital market in china

The pension funds entering the capital market is the trend of the times, how to ensure the security of pension funds after entering the market, it is not only related to the interest of the individual but also affect the society＇s harmonious development. This article begins with the concept of pension funds into the market, the urgency and necessity of the pension funds into the market in our country and the actual situation of the pension regulators at present. According to analysis the problems existing in the pension market regulation, then putting forward countermeasures and measures, paving the way for pension funds entering the market in our country.

Rationality and Risk Management of the Basic Old-age Insurance Fund Invested in the Capital Market

With the accelerated development of population aging, the pressure to pay for the future pension fund in our country is increasing. Affected by many factors, such as investment limits, inflation and interest rate cut, the rate of return on investment is very low. The introduction of the new policy allows the basic pension fund to enter the capital market, which is of great significance to improve the rate of return on investment, ease the pressure of capital gap, and promote the healthy development of the capital market. This paper makes a deep analysis of the rationality of the basic endowment insurance fund entering the market, and then puts forward some suggestions to avoid the risk of the pension market.

Temporal-spatial Variations of Dynamic Source Parameters in the Capital Circle Region and Its Surrounding Areas before the 2006 M_S5.1 Wenan Earthquake in Hebei Province

Source spectra,corner frequency and zero frequency amplitudes in near-source conditions were measured using waveform data from 989 earthquakes with magnitudes larger than ML2.0 observed by the Beijing Digital Telemetry Seismic Network in the Capital Circle Region of China and its surrounding areas from January 2002 to June 2006 by the Brune model.Relevant formulas that were used for the calculation of dynamic source parameters include rupture radius,seismic moment,seismic energy,stress drop,and apparent stress.Scaling relations and characteristics of temporal-spatial variations of these dynamic parameters before the MS5.1 Wenan earthquake in Hebei Province that occurred on July 20,2006 were analyzed.Results show that apparent stress,stress drop,and the ratio of seismic energy to the rupture radius had relatively high values in some areas before the Wenan earthquake.These high-value concentration areas were mainly distributed in the North China Plain seismic zone.As is seen from the time curves,parameters,such as apparent stress,stress drop,and ratio of seismic energy to rupture radius underwent significant ascending processes before the Wenan earthquake,but the variation in the corner frequency showed a descending trend.This result might be related to the enhancement of stress in the North China Plain seismic zone before the earthquake.

Leaving the Capital Behind

A number of impressive and relaxing tourist attractions make northeast Hebei a worthwhile trip outside Beijing When it comes to culture and tourism,Hebei Province can’t compete with the imperial palaces,temples,summer resorts and other ancient landmarks of Beijing.The province is also missing them useums and monuments to the people’s heroes.But what it lacks in epic tourist attractions Hebei makes up for with smaller,quainter sights that provide a pleasant respite from the busy city life and crowded tourist hotspots of the Chinese capital.

Four Imagination Matrices of Chinese Myth

This paper discusses four Imagination Matrices of Ancient Chinese Myth.The first one is“Heaven Ladder”,which is believed to have the function of traffic means between upper universe and middle one.And Jianmu is a special Heaven Ladder which is used especially by gods.The second one is the“Capital of God on the Earth”,which is regarded as the reign center of God on the earth.It located at the Mount Kunlun in the northwest of China.Opposite to the lofty Mount Kunlun into heaven,Gui Xu,the third matrix,is a bottomless valley in the east of the Bohai Sea.Gui Xu is another center for gods’activities.The last one is Huangquan Road,the lower universe,which means the world after death for the ancient people.
