9指令制导导弹脱靶量的分析显示文摘本文给出了一种估计综合比例导航指令制导导弹系统最小可能脱靶量的简洁的理论技术。分析表明系统参数值对系统能力的影响是拦截距离的函数。系统的设计和分析人员可以利用这项技术对系统的性能进行定量分析,对指令制导系统在各个拦截距离上的性能限制有一个系统的理解。本文根据伴随理论推导出由目标机动、伺服、闪烁、大气以及取决于距离的指令制导系统噪声所引起的统计脱靶量的新解析式。本文引出了一个最佳的系统总时间常数,在这种情况下可以获得最小的统计脱靶量。本文还考虑了可实现的最小系统时间常数的实际限制。为最佳系统总时间常数所推导出的一系列公式对于系统设计人员尽量减小各种系统参数和限制以及拦截条件下的脱靶量是很有价值的。Joel Alpert 李吉良 1989系统工程与电子技术1989,11,6:2
10Differences in physiological integration between invasive and noninvasive introduced clonal species of Carpobrotus显示文摘Aims Clonal growth is associated with invasiveness in introduced plant species,but few studies have compared invasive and noninvasive introduced clonal species to investigate which clonal traits may underlie invasiveness.To test the hypothesis that greater capacity to increase clonal growth via physiological integration of connected ramets increases invasiveness in clonal plants,we compared the effects of severing connections on accumulation of mass in the two species of the creeping,succulent,perennial,herbaceous genus Carpobrotus that have been introduced on sand dunes along the Pacific Coast of northern California,the highly invasive species Carpobrotus edulis and the co-occurring,noninvasive species Carpobrotus chilensis.Methods Pairs of ramets from four mixed populations of the species from California were grown in a common garden for 3 months with and without severing the stem connecting the ramets.To simulate the effect of clones on soils in natural populations,the older ramet was grown in sand amended with potting compost and the younger in sand alone.Important Findings Severance decreased net growth in mass by~60%in C.edulis and~100%in C.chilensis,due mainly to the negative effect of severance on the shoot mass of the younger ramet within a pair.Contrary to the hypothesis,this suggests that physiological integration increases growth more in the less invasive species.However,severance also decreased allocation of mass to roots in the older ramet and increased it in the younger ramet in a pair,and the effect on the younger ramet was about twice as great in C.edulis as in C.chilensis.This indicates that the more invasive species shows greater phenotypic plasticity in response to physiological integration,in particular greater capacity for division of labor.This could contribute to greater long-term growth and suggests that the division of labor may be a trait that underlies the association between clonal growth and invasiveness in plants.Sergio R.Roiloa Peter Alpert Rodolfo Barreiro 2019Journal of Plant Ecology2019,12,6:2
