Background:Potassium(K)deficiency has become a common field production problem following the widespread adoption of Bacillus thuringiensis(Bt)transgenic cotton(Gossypium hirsutum L.)*** purpose of this study was to clarify whether the introduction of Bt gene directly reduces the K-use efficiency of cotton to induce K ***:The cotton variety,Jihe 321(wild type,WT)and its two Bt(Cry1Ac)-transgenic overexpression lines(OE-29317,OE-29312)were studied in field with low soil-test K+(47.8 mg·kg^(−1)).In the field with low soil-test K+,only OE-29317 had less biomass and K+accumulation than the WT at some growth *** Bt lines produced similar or even greater seed cotton yield than WT in the *** the Bt gene(~70%)in OE-29317 and OE-29312 plants was silenced by virus-induced gene silencing(VIGS),the VIGS-Bt plants did not produce more biomass than VIGSgreen fluorescent protein(control)***:The introduction of Bt gene did not necessarily hinder the K use efficiency of the cotton lines under this study.

深低温环路热管是一种高效的深低温两相传热器件,未来可广泛应用于红外探测等空间项目的低温热控系统。为有效减小热管与热负荷间的接触热阻及热管的背向漏热,采用氧化锆作为毛细芯材料,研发了氮工质平板蒸发器环路热管,重点研究了热管的自启动特性、传热性能以及在间歇性热负荷下的运行情况。结果表明:在无辅助情况下,液氮温区平板蒸发器环路热管自启动性能良好,可依靠工质扩散从室温迅速降温至液氮温区。环路热管能够在70~100 K温区稳定运行,热阻随运行温度和热负荷的上升而减小,最大传热功率为15 W,最小热阻为0. 8 K/W。在蒸发器间歇性加热的情况下,环路热管可以保持温度稳定,热响应迅速,无需二次降温。液氮温区平板蒸发器环路热管有效满足了空间低温光学系统的热控制系统的热传输需求。

名校集团是教育行政部门主导的,以快速分享名校优质资源为目的的一类公办教育组织化推进模式,名校运用信息化技术手段共享优质教育资源的尝试取得了一些成效,很多大城市都实施了名校集团化模式。这次新型冠状病毒疫情的袭来,更促使人思考优质教育资源普惠化和便捷化分享的有效途径,理顺名校集团的运行机制及其面临的制度问题,有助于完善突破地域对资源共享限制的认知。名校集团组织面临多维的制度环境,包括名校自身理性发展、政府和社会三个维度。制度环境共同形塑了名校组织形式的合法性,导致区(县)域内发展和全域发展两个历史阶段。当下名校集团的组织运行隐含名校资源集中化需求与名校组织规模扩大的制度矛盾,其焦点就是名校的人力资本资源。区级政府与名校自身更愿意扩大名校内编和财政收入,市级政府则倾向于给弱校和新校编制和财政支持,以鼓励名校师资向下流动。作为一种组织结果,名校集团选择派出少量管理及教师人员这一套非正式制度来化解制度矛盾,因此容易出现存在资源分享力度低的这一类普遍性问题。本文最后提出全域教育技术现代化、城乡教育联盟、教育投入多元化三个方面的建议,来完善名校集团化解制度矛盾的策略,提升分享不可复制资源的力度。
