Nit.ogenous fert.lisers are under considerat.on for promot.ng t.e growt. of nursery-reared hoop pine （Araucaria cunninghamii Alt.n ex A.

Four seedlings from each t.eat.ent.were harvest.d at.4-mont. int.rvals, divided int. root., st.m and foliage, wit. a furt.er subdivision for new and old foliage, and t.en analysed for ^15N, t.t.l N, δ^13C and t.t.l C. t.ere was no significant.response in t.e seedling growt. t. t.e form or rat. of applicat.on of nit.ogen （N） fert.liser wit.in t.e 12-mont. period, indicat.ng t.at.t.e seedlings did not.experience N deficiency when grown on second rot.t.on hoop pine soils.

t.e ball and plat. syst.m is an inherent.y nonlinear under act.at.d benchmark syst.m used for validat.ng t.e performance of various cont.ol schemes. A mat.emat.cal model depict.ng t.e dynamics close t. t.at.of t.e syst.m is very much required for such a t.st.bed. In t.is correspondence, t.e complet. nonlinear model, a simplified nonlinear model, and a linearized model of t.e ball and plat. syst.m are developed. t.e syst.m comprises a ball and plat. mechanism and a rot.ry servo unit. t.e ball and plat. mechanism is modelled using t.e Euler–Lagrange met.od, whereas t.e rot.ry servo subsyst.m is modelled from t.e first.principles. t.e nonlinear model of t.e combined syst.m is developed by including t.e dynamics of t.e servo mot.r wit. gear and rolling resist.nce bet.een t.e ball and t.e plat.. t.e simplified nonlinear model of t.e syst.m is obt.ined wit. suit.ble assumpt.ons. t.e model is linearized around t.e operat.ng point.using t.e j.cobian. t.e validit. of t.e developed models is invest.gat.d t.rough correlat.on funct.on analysis. t.e open-loop response of t.e t.ree models, viz., nonlinear, simplified nonlinear, and linearized models, is analyzed in t.e MAt.AB/Simulink plat.orm. Since t.e open-loop syst.m is unst.ble, t.e experiment.l validat.on of t.e model is performed wit. a double-loop PSO (part.cle swarm opt.mizat.on) PID cont.ol scheme.

当代西方新唯物主义的共识在于质疑人类中心主义预设,并要求恢复物质自身的活力。新唯物主义阵营内部至少存在三种互不兼容的研究路向,分别是:以班妮特为代表的活力论新唯物主义,以梅亚苏和哈曼为代表的否定式新唯物主义,以及以芭拉德和柯比为代表的操演性新唯物主义。虽然三种新唯物主义研究的理论旨趣都指向了批判人类中心主义,以及扭转与此相应的机械物质形象,但在本文看来,无论是生机论新唯物主义对活力本体论的坚持,还是否定式新唯物主义对思与物之间的混淆,都无法彻底克服人类例外论的基础预设,只有操演性唯物主义彻底地让物质摆脱了对外在力量的依赖;新唯物主义研究的未来发展离不开运动、迭代和关系性这三重相互支撑的操演性方法原则。
