It is shown that there is something wrong with AMSAA_BISE model. According to AMSAA_BISE model, the maximum likelihood estimation of MTBF for multiple systems reliability growth test is much larger than that according to AMSAA model for a single system; The more systems is put into test, the larger the estimation of MTBF. An example is given, and an approximate method is presented.展开更多

Since the 16 th National Congress of the Communist Party of China( CPC),there have been fundamental changes in China's agricultural policies. The works of three rural issues with the development of modern agriculture rapidly became the main topic. The practice promoted researches of agricultural modernization in the connotation,characteristics,path selection,and indicator system construction. With the introduction of simultaneous development of " four modernizations" and coordinated development of " five modernizations",the theoretical researches of China's agricultural modernization have been provided with new connotations. In the existing achievements of " four modernizations" and " five modernizations" containing agricultural modernization,the characteristics,paths,indicator system and evaluation methods of agricultural modernization are constantly enriched. Through sorting out the theoretical achievements in the researches about agricultural modernization since the 16 th CPC National Congress of the CPC,this paper explored the new characteristics,new paths and new indicator system of agricultural modernization,to provide reference for the further transformation and upgrading of China's agriculture and the formulation of relevant policies.展开更多
