However, it is still on debate regaralng wnemer the development of auditory synapses is dominated by acquired sound stimulations. In this review, we summarize relevant publications in recent decades to address this issue. Most reported data suggest that extrinsic sound stimulations do affect, but not govern the development of periphery auditory synapses. Overall, periphery auditory synapses develop and mature according to its intrinsic mechanism to build up the synaptic connections between sensory neurons and/or interneurons.展开更多

The periphery is an in- termediary agent between the system and its environment, and has two functions： defending system itself and exchanging with the environment. Generally, the periphery is defined on space dimension. We will investigate the periphery from the time dimension, and study a time jieke based on set theory viewpoint; initial values and forecast lead in weather forecast are clarified. Further predictability of weather forecast on the basis of periph- ery theory is defined; its calculation formulae are given, with which computing for day-to-day forecast were carded out. The results have been com- pared with present researches of atmospheric predictability, and it shows advancing the predictability study. Most interesting is that atmospheric pre- dictability possesses rule of gold ratio 0.618, and it is found firstly in research of weather and climate predictability.展开更多

Vegetation is an important part in the ecosystem and it is an important index indicating certain landscape. Based on several times field investigation, this paper attaches importance to the feasible measures for vegetation restoration according to the current condition of study area – Qira County of Xinjiang Uygur Autonomous Region. In order to improve the local ecological environment, people lived in Qira County should work hard to protect their homeland and reduce the degree of sandstorm. More protection forest should be established along with other ecological techniques. Results derived from this study contribute largely to the ecological environmental protection of oasis.展开更多
