查询词典 unstability

1Unequal number of univalents with decreased degree of synapsis and lagging chromosomes occurred in meiosis.The abnormal chromosomal behavior correlated with heterogenicity gave rise to unequal allocation of homogenous chromosomes to daughter cells and resulted in the deletion of functional chromosoms,thus led to the occurence of a certion proportion of aborted pollens.(2)The interaction between genetic imbalance and such environmental factors as temperature,etc.,further drew forth physiological and even structrural imbalance,with abnormal development of pollen mother cells and tapetal cells,and consequently resulted in no or very few production of pollens.The difference in the interaction between environment and genotype reflected on the unstability of pollen abortion in different years.

According to the Russian archives revealed in recent years and the recollections of the Soviets concerned,the article makes an objective analysis of the historical background,causes of the events and the leaders'motives,ways to deal with the disputes.The author indicates that although the Soviets displayed great-nation chauvinism to a certain degree,yet they had not the intention to violate China's sovereignty.While Mao Zedong forced Nikita Khrushchov to give in by making extremist response to these questions,he created psychological obstacles for further cooperation between the two countries.The original reason of their unconsummated military cooperation was the inherent unstability within the socialist alliance.

引用近几年披露的俄国档案文献及苏方当事人的回忆，文章对上述事件的历史背景、原由以及两国领导人处理问题的动机和方式进行了较为客观的分析，认为实现军事合作是中苏双方的愿望；苏联在与中国交往中确有某种程度的领导者心态，但并没有任何侵犯中国主权的意图；在长波电台和联合舰队问题上，毛泽东作出过激反应，其结果虽然迫使赫鲁晓夫屈服，却给中苏进一步的军事合作制造了心理障碍；中苏最终未能实现军事合作的根源在于社会主义阵营同盟关系内在的不稳定性。

The geology research of carbonate reservoirs in Ordovician of Tahe oilfield showed that many large dissolved vugs and fractures were developed. The spread of the reservoir take on a very heterogeneous state. And the typical fractured-vuggy reservoirs was formed. According to the combination of the various spaces, the formation was divided into vuggy formation, fractured-vuggy formation and fractured formation. The research showed that development of the vug is relevant to the its position on the structure, the fractures, the water surface and the weathering surface. Multi-phase charge and recharge of the oil in the reservoirs resulted in the complexity of the fluid distribution. So the"Bottle Model"was brought forward to explain the movement of the water-oil contact. The special storage space and the complex fluid distribution lead to the unstability of the production and the complexity of the water cut. In order to explain the characteristic of the fracture-vug unit was brought forward and the basic principle and method of the partition of the fracture-vug unit was formed. The classification and evaluation of the units were performed according the reserve and energy. Based on the research of geology characteristic and the fluid flow in the reservoir the comprehensive numerical simulation plan of the fractured-vuggy reservoirs were established. Through the selection of the simulation unit, fluid flow type and parameter equivalent the triple media reservoir simulation model was established. Considering the practical application the model was resolved by the DKR decomposition conjugate grads method. Based on the fine reservoir description of Dsitrict IV of the Tahe oilfield the various space type were classified and combined together. The geology model of Unit S48 was constructed. Two typical single well model was established according to the geology and the dynamic phenomena. Finally the single well model and the Unit S48 were simulated by the triple media reservoir simulator. Via the local grid refinement and coarsening in the simulation good matchs were gained. Based on the results of the simulation the reserve distribution, percent of reserve produced in various space and the natural energy were analyzed. The fluid was storaged in the fractures and vugs mostly and more than 90% the produced oil came from the systems. The energy belonged to the active one. The results of simulation accorded with the fact and showed the validity and practicability the research and the simulator.
