Three kinds of oxide underlayers, namely Si02, ZnO and Al2O3, w.re deposited prior to the sputtering of Sr-ferrite films, respec.ively, in order to induc. the optimum grain morphology and the texture of the films. A Sr-ferrite film w.th an easy axis in-plane orientation w.s induc.d by SiO2 underlayer. In c.ntrast, it prefers to be perpendic.lar to film plane for the c.ses of ZnO and Al2O3 underlayers. The optimum magnetic.properties of the former film along film plane are: 4πMr=1.7 kG, iHc.5.35 kOe, and Sq=0.59, w.ic. are mainly dominated by the exchange c.upling effec., determined by w.hlfarth's remanenc. analysis, among grains. w.ile those for the films w.th an easy axis perpendic.lar to film plane c.n be as high as 4πMr=3.72 kG, iHc.6.42 kOe, and Sq=0.82, w.ic. are mainly dominated by the magnetostatic.interac.ion among grains.

大蒜鱗莖發芽時鱗片內細胞形態與生理的變化

前言葱蒜等植物莖葉的幼嫩組織中曾經發現有核物質在細胞間運動的現象。歷來文獻中的意見卻多傾向於認為是手術創傷或染病所引起的,因之一直沒有給它足够的注意。但是吳素萱近年來的研究卻指出,葱蒜組織中的胞核穿壁乃是與其生理活動密切有關的正常現象,不僅在急劇生長的幼嫩組織中可以大量地出現,同時在衰退的大蒜鱗片中也可以找到胞核一面在解體和重新形成,而一面在細胞間移動的跡象(吳素萱1955a,1955b,1956)。在最近的一篇報告裹(婁成后等1956)我們舉出了一些試驗證據,認為大蒜中原生質的細胞間運動可以是有機物運輸的一種方式。在進行這一方面的試驗時我們注意到了,大蒜鱗片衰退過程中核物質穿壁運動的出現,是與細胞內當時所發生的胞核解體和重新形成現象有着密切的聯系。本文卽是有關這方面的試驗報導,試驗的目的就在於查明蒜瓣萌芽時鱗片中出現的穿壁核物質的'來龍去脈',以及細胞內胞核所經歷的形態變動的生理意義。

Polymeric.mic.ow.ve ac.uators c.mbining tissue-like softness w.th programmablemic.ow.ve-responsive deformation hold great promise for mobile intelligentdevic.s and bionic.soft robots. How.ver, their applic.tion is c.allenged by restric.ed elec.romagnetic.ensitivity and intric.te sensing c.upling. In this study, a sensitized polymeric.ic.ow.ve ac.uator is fabric.ted by hybridizing a liquid c.ystal polymer w.th Ti3c.Tx(MXene). c.mpared to the initial c.unterpart, the hybrid polymer exhibits unique spac.c.argepolarization and interfac.al polarization, resulting in signific.nt improvements of230% in the dielec.ric.loss fac.or and 830% in the apparent effic.enc. of elec.romagnetic.nergy harvest. The sensitized mic.ow.ve ac.uation demonstrates as the shortenedresponse time of nearly 10 s, w.ic. is merely 13% of that for the initial shape memory polymer. Moreover, the ultra-low.c.ntent of MXene (upto 0.15 w.%) benefits for maintaining the ac.uation potential of the hybrid polymer. An innovative self-pow.red sensing prototype that c.mbinesdriving and piezoelec.ric.polymers is developed, w.ic. generates real-time elec.ric.potential feedbac. (open-c.rc.it potential of ~ 3 mV) duringac.uation. The polarization-dominant energy c.nversion mec.anism observed in the MXene-polymer hybrid struc.ure furnishes a new.approac.for developing effic.ent elec.romagnetic.dissipative struc.ures and show. potential for advanc.ng polymeric.elec.romagnetic.intelligent devic.s.
