In this paper a new model is derived for synthetic assessment of system reliability according to the nature of information entropy and reliability theory. It gives a solution to the problem of reliability information synthesis of the component units of system. 本文根据信息熵的性质和可靠性理论,推导出系统可靠性综合评定的新模型,解决了系统各组成单元的可靠性信息综合问题。
Secondly, the component units of the laser are designed, including the optimal design of the laser crystal, the selection of the pump mode, the research on the gain distribution within the laser crystal, and the cavity design. 其次,对高功率全固态激光器的组成单元进行了设计,主要包括激光晶体的优化设计、泵浦方式的选择、工作物质内部增益分布研究、谐振腔的设计等。
DNA and RNA damage can affect one of its component units, but only the loss or change that has genetic consequences of the nucleic acid bases. 可影响DNA、RNA的损伤其某一组成单元,但只有核酸碱基的丢失或者改变才具有遗传后果。
Public Park is an important part of urban green space. The plant community is the basic component units of urban green space which structure determine the plant landscape quality and the ecological function of urban green space. 公园绿地是构成城市绿地的重要组成部分,而植物群落是绿地的基本构成单位,其结构特征对公园绿地内植物景观的质量和生态功能的发挥起着决定性的作用。
In accordance with the sedimentary characteristic of the carbonate strata area, meter-scale cyclic sequences, which are component units of third-order sequence, are applied as elementary study units to field survey and record, and indoor research. 针对海相碳酸盐岩地区的沉积特点,使用米级旋回层序作为三级层序的组成单元进行室内和野外研究。
