Ecological civilization,as a forthcoming civilization form,highlights the sustainable development and the pursuit of harmony between man and nature. Pre-Qin Confucian ecological thought can provide useful ideological resources for the cultivation of ecological consciousness and the construction of ecological civilization.展开更多

Through the research on relevant materials of old Shu Kingdom, and by comparing with the archaeological discovery of Yangzi Mountain Terrace, the paper has proposed that the origin of Sichuan gardens can trace back to gardens in the period of Duyu King. It is considered that gardens in pre-Qin period are dominated by imperial gardens, emperors' or aristocratic cemeteries, among which the historical function and features of Yangzi Mountain Garden, Nanzhong Garden and Wudan Mountain Cemetery have been introduced. On this basis, characteristics of Sichuan gardens in pre-Qin period have been concluded, and the grand manner manifested through "Great Stone Worship" in ancient Shu Kingdom has been highlighted.展开更多

Using rich historical data such as archeology,anthropology and ethnology,this paper discussed the historical process of agricultural religion in the pre-Qin period from animal worship to agricultural worship. It also discussed the agricultural objects,land,celestial nature,and labor ghosts.Finally,it revealed the inevitable trend of combination of social sacrificing activities.展开更多

In order to provide a technical support to expand the high altitude ignition envelope of aero-engines, in this article we propose a novel ignition technology, i.e., "precombustion plasma jet ignition technology". In this paper, we also design a pre-combustion plasma jet igniter. Its discharge characteristics, jet characteristics, and ignition effects are studied. The results show that increasing the equivalent ratio of jet gas can enhance the discharge stability and increase the duty cycle. At the same time, it can reduce working power and energy consumption. The increase of equivalent ratio in jet gas can enhance the length and ignition area of plasma jet.In the process of ignition, the pre-combustion plasma jet igniter has obvious advantages, suchn as shortening the ignition delay time and enlarging the ignition boundary. When the airflow velocity is 39.11 m/s and the inlet air temperature is80℃, compared with the spark igniter and the air plasma jet igniter, the pre-combustion plasma jet igniter has an ignition boundary that is expanded by 319.8% and 55.7% respectively.展开更多

In order to verify and test this phenomenon,a real-time tracking technical system was established by using continuous waveform records of more than 200 wide-band digital seismic stations in regional networks such as Gansu,Qinghai,Sichuan,Yunnan and Tibet.Through real-time tracking and dynamic monitoring of 24 earthquakes with M≥5. 0 occurring in the Qinghai-Tibetan block during the period of 2012-2014 and the observations of stations in some non-seismic areas,the reproducibility and objectivity of the impending earthquake phenomenon were verified. The main characteristics of the microseismic fluctuation phenomena immediately preceding the strong earthquakes are as follows:(1)the spectrum range is wider,the dominant frequency is 11-16 Hz,and the spectrum shape is more regular;(2)it appears 6-24 days before the earthquake,averaging about 15 days;(3)it is possible to be recorded by the stations within the epicenter distance of 50 km,and the stations with the epicenter distance of more than 50 km generally cannot record it;(4)this phenomenon is directional,i. e. the direction in which the activity degree,N-value,varies significantly may be related to the location of the seismic source,the seismogenic fault and the distribution of aftershocks of the strong earthquake. The preliminary study shows that the impending-earthquakes microseismic phenomena may be related to the pre-activity,micro-vibration and micro-rupture in the source region in the imminent stage,or the microactivity and micro-rupture associated with the active tectonics.展开更多
