There are three distinct genetic systems in higher plants,the dominant nuclear genome and the semi-autonomous organelle genomes(plastids and mitochondria).In contrast to the conserved plastid genome(plastome),the plant mitochondrial genome(mitogenome)is characterized by an intriguing“evolutionary paradox”distinguished by a remarkably low mutation rate but with a significantly high rearrangement rate(Palmer and Herbon,1988;Lai et al.,2022).

根据刚性拘束裂纹试验机理,自主研制了国内首台大吨位高强钢刚性拘束焊接冷裂纹倾向试验装置,其具有精准的测量系统,完全适应48 h的拘束应力维持时间,该机可提供最大1 200 k N的试验力。利用该冷裂试验装置进行E36钢板对接接头刚性拘束裂纹试验,对比分析GFL-71NI焊丝(国产)和DW-A55L焊丝(进口)的冷裂纹敏感性。结果表明,通过药芯焊丝气体保护焊接方法施焊,采用GFL-71NI焊丝获得接头的临界拘束距离大于DW-A55L焊丝接头,经计算GFL-71NI焊丝接头的临界拘束度和临界拘束应力均小于DW-A55L焊丝接头,最终得到GFL-71NI焊丝接头的冷裂敏感系数高于DW-A55L焊丝接头,数值分别为0.345 147和0.326 094,表明DW-A55L焊丝的抗冷裂性能优于GFL-71NI焊丝。金相分析显示,与GFL-71NI焊丝接头相比,DW-A55L焊丝接头焊缝组织更均匀,晶界铁素体含量明显减少;过热区组织中的淬硬组织含量也较少,这显著降低了DW-A55L焊丝接头的冷裂倾向。

Nonadiabatic holonomic quantum computers serve as the physical platform for nonadiabatic holonomic quantum *** quantum computation has entered the noisy intermediate-scale era, building accurate intermediate-scale nonadiabatic holonomic quantum computers is clearly necessary. Given that measurements are the sole means of extracting information, they play an indispensable role in nonadiabatic holonomic quantum computers. Accordingly, developing methods to reduce measurement errors in nonadiabatic holonomic quantum computers is of great importance. However, while much attention has been given to the research on nonadiabatic holonomic gates, the research on reducing measurement errors in nonadiabatic holonomic quantum computers is severely lacking. In this study, we propose a measurement error reduction method tailored for intermediate-scale nonadiabatic holonomic quantum computers. The reason we say this is because our method can not only reduce the measurement errors in the computer but also be useful in mitigating errors originating from nonadiabatic holonomic gates. Given these features,our method significantly advances the construction of accurate intermediate-scale nonadiabatic holonomic quantum computers.

苏铁蕨(Brainea insignis)最早出现于古生代泥盆纪,是重要孑遗种和珍稀濒危植物,对研究古植物区系及蕨类植物的起源和演化具有重要意义。该研究采用相邻格子法对深圳市径心水库区的苏铁蕨群落进行群落学研究,分析径心水库区苏铁蕨群落结构和演替特点,为苏铁蕨的保护提供理论和实践依据。结果表明:(1)深圳径心水库区的苏铁蕨群落属于南亚热带常绿阔叶林,在1 600m2的样地中共有维管束植物72种,隶属于45科66属,其中种类组成以热带成分占绝对优势,占非世界属的88.33%。(2)该苏铁蕨群落垂直结构明显,可划分为乔木2亚层、灌木层和草本层,层间植物较丰富;各种群的重要值分析表明,鸭脚木(Schefflera octophylla)、苏铁蕨(Brainea insignis)、九节(Psychotria rubra)、鼠刺(Itea chinensis)、银柴(Aporusa dioica)是该群落的主要优势种,其重要值分别为:53%、38%、28%、23%和22%。(3)年龄结构分析表明,主要优势种群如银柴、鼠刺和豺皮樟(Litsea rotundifolia)等均属于增长型种群,而苏铁蕨种群却呈现出一定的衰退趋势,说明该群落正处在旺盛发展阶段并且会不断演化替换掉苏铁蕨种群。(4)该研究区群落种群的频度规律为A级>B级>C级>D级
