Because of wide adaptability and high survival rate, it is widely grown in various countries, being one of the world's ten most important oil crops. Castor has very wide application range, which is recognized as the most promising plant oil in deep processing instead of oil. It has very high development and utilization value, and has been paid attention by a large number of researches. However, the current interna- tional castor seed breach is serious, so the development and utilization of castor in- dustry is restricted. Castro breeding research in China began in early 1950s. Cur- rently, castor breeding technology and variety yield level in China have reached in- ternational advanced level. Although great improvement has been made, there still have space in many ways. Based on long-term castor breeding practice, the paper discusses the feasibility and importance of using wild resources, native variety and imported varieties to improve and innovate germplasm resources of castor, and breed disease-resistant inbred lines and hybrids. According to regional characteristics of castor cultivation in China, the main breeding objectives including high yield and high oil, suitable for mechanized cultivation, high resistance and strong stress toler- ance are put forward in the paper.展开更多

The advanced prediction of them has become a hotspot. Based on analysis of physical characteristics of the disaster sources and comparative evaluation of accuracy of the main advanced geophysical detection methods, we proposed a comprehen- sive judging criterion that tectonic interface can be judged by the elastic wave energy anomaly, strata water abundance can be discriminated by apparent resistivity response difference and establish a reason- able advanced prediction system. The results show that the concealed disaster sources are detected effec- tively with the accuracy rate of 80% if we use advanced prediction methods of integrated geophysics combined with correction of seismic and electromagnetic parameters, moreover, applying geological data, we may then distinguish types of the disaster sources and fulfill the qualitative forecast. Therefore, the advanced prediction system pays an important referential and instructive role in laneway driving project.展开更多

The utilization of the wild abortive cytoplasmic male sterility (CMS) in 1970s has significantly raised rice yield potential. But the world's annual rice production will have to increase 70 percent over the next 30 years, to keep up with the demends of the growing population.展开更多

Then, a new complexity scalable control algorithm for intra coding in H. 264 is proposed, based on the rearrangement of the order of candidate modes and an efficient complexity allocation and control (CAAC) scheme at the macroblock (MB) level. The candidate modes of each MB are rearranged according to the local-edge information. Experimental results show that our proposed algorithm can make an appropriate cut-off point of the candidate modes sequence adaptively according to the current energy condition of a mobile device, so as to adjust the complexity at any level while maximizing the video quality, which can prolong the operational lifetime of the battery with minimum degradation in video quality.展开更多
