Evidence for episodic crustal growth extending back to the Hadean has recently prompted a number of numerically based geodynamic models that incorporate cyclic changes from stagnant lid to mobile lid tectonics. A large part of the geologic record is missing for the times at which several of these cycles are inferred to have taken place. The cratons, however, are likely to retain important clues relating to similar cycles developed in the Mesoarchean and Neoarchean. Widespread acceptance of a form of plate tectonics by ～3.2 Ga is not at odds with the sporadic occurrence of stagnant lid tectonics after this time. The concept of scale as applied to cratons, mantle plumes and Neoarchean volcanic arcs are likely to provide important constraints on future models of Earth's geodynamic evolution. The Superior Province will provide some of the most concrete evidence in this regard given that its constituent blocks may have been locked into a stagnant lid relatively soon after their formation and then assembled in the next global plate tectonic interval. Perceived complexities associated with inferred mantle plume — volcanic arc associations in the Superior Province and other cratons may be related to an over estimation of plume size. A possible stagnant lid episode between ～2.9 Ga and ～2.8 Ga is identified by previously unexplained lapses in volcanism on cratons, including the Kaapvaal, Yilgarn and Superior Province cratons. If real, then mantle dynamics associated with this episode likely eliminated any contemporaneous mantle plume incubation sites, which has important implications for widespread plumes developed at ～2.7 Ga and favours a shallow mantle source in the transition zone. The Superior Province provides a uniquely preserved local proxy for this global event and could serve as the basis for detailed numerical models in the future.

To better understand Earth's present tectonic style-plate tectonics—and how it may have evolved from single plate(stagnant lid) tectonics, it is instructive to consider how common it is among similar bodies in the Solar System. Plate tectonics is a style of convection for an active planetoid where lid fragment(plate) motions reflect sinking of dense lithosphere in subduction zones, causing upwelling of asthenosphere at divergent plate boundaries and accompanied by focused upwellings, or mantle plumes;any other tectonic style is usefully called "stagnant lid" or "fragmented lid". In 2015 humanity completed a 50+ year effort to survey the 30 largest planets, asteroids, satellites, and inner Kuiper Belt objects,which we informally call "planetoids" and use especially images of these bodies to infer their tectonic activity. The four largest planetoids are enveloped in gas and ice(Jupiter, Saturn, Uranus, and Neptune)and are not considered. The other 26 planetoids range in mass over 5 orders of magnitude and in diameter over 2 orders of magnitude, from massive Earth down to tiny Proteus; these bodies also range widely in density, from 1000 to 5500 kg/m^3. A gap separates 8 silicate planetoids with ρ = 3000 kg/m^3 or greater from 20 icy planetoids(including the gaseous and icy giant planets) with ρ = 2200 kg/m^3 or less. We define the "Tectonic Activity Index"(TAI), scoring each body from 0 to 3 based on evidence for recent volcanism, deformation, and resurfacing(inferred from impact crater density). Nine planetoids with TAI = 2 or greater are interpreted to be tectonically and convectively active whereas 17 with TAI lid tectonics is the dominant mode of heat loss and that plate tectonics

Although Plate Tectonics cannot be effectively tested by palaeomagnetism in the Precambrian aeon due to the paucity of high precision poles spanning such a long time period,the possibility of lid Tectonics is eminently testable because it seeks accordance of the wider dataset over prolonged intervals of time;deficiencies and complexities in the data merely contribute to *** of palaeomagnetic poles across a quasi-integral continental crust for time periods of up to thousands of millions of years,together with recognition of very long intervals characterised by minimal polar motions(～2.6-2.0,～1.5-1.25 and～0.75-0.6 Ga)has been used to demonstrate that lid Tectonics dominated this *** new PALEOMAGIA database is used to refine a model for the Precambrian lid incorporating a large quasiintegral crescentric core running from South-Central Africa through Laurentia to Siberia with peripheral cratons subject to reorganisation at～2.1,～1.6 and～1.1 *** model explains low levels of tidal friction,reduced heat balance,unique petrologic and isotopic signatures,and the prolonged crustal stability of Earth's"Middle Age",whilst density concentrations of the palaeomagnetic poles show that the centre of the continental lid was persistently focussed near Earth's rotation axis from～2.8 to 0.6 *** exception was the～2.7-2.2 Ga interval defined by～90°polar movements which translated the periphery of the lid to the rotation pole for this quasi-static period,a time characterised by glaciation and low levels of magmatic activity;the～2.7 Ga shift correlates with key interval of mid-Archaean crustal growth to some 60-70%of the present volume and REE signatures whilst the～2.2 Ga shift correlates with the Lomagundiδ～(13)C and Great Oxygenation *** palaeomagnetic signature of breakup of the lid at～0.6 Ga is recorded by the world-wide Ediacaran development of passive margins and associated environmental signatures of new ocean *** event defined the end of a

雨水径流总量控制作为城市低影响开发(Low Impact Development,lid)重要目标之一,对降雨选用何种控制模式(方式)是个重要的问题。本文通过理论分析与实际监测检验,对不同汇流关系下lid降雨控制方式的区别进行了分析研究。理论分析结果表明,lid设施与不透水地表之间依汇流方式不同可以分为串联、并联两种关系形式,分别对应不同的降雨控制方式。对于小于设计降雨量的降雨,前者为场次控制,后者为部分控制;对于大于设计降雨量的降雨,两者均为部分控制。从各场次降雨控制总量来看,前者略大于后者;从对地下水涵养、径流水质改善和流量峰值削减角度而言,前者效果要优于后者。因此,对于lid雨水径流控制效果的检验,不能仅限于降雨总量控制率的统计,还需分析判别lid降雨控制的方式,尽量选用串联的汇流形式。以北京未来科技城为例,对其lid雨水径流控制效果与方式进行了分析检验。结果表明,虽然监测期内雨水总量控制率可以达到≥85%的目标,但对小于设计降雨量的场次降雨未能实现场次控制,原因在于区内不透水车道与两侧绿化带未按规划实现串联布置,后期有待加以改进。

由于等离子体增强化学的气相沉积(PECVD)法制备的SiO_(x)N_(y)薄膜中含有大量H原子,因而具有优异的表面钝化性能。通过在PERC太阳电池的Al_(2)O_(3)/SiN_(x)背钝化叠层中间插入一层SiO_(x)N_(y)薄膜,形成Al_(2)O_(3)/SiO_(x)N_(y)/SiN_(x)结构,可避免SiN_(x)所带的固定正电荷对Al_(2)O_(3)负电荷场钝化效应的负面影响。试验结果表明,硅片少子寿命从原来的130μs提高至162μs,电池转换效率增加0.09%。同时,基于Al_(2)O_(3)/SiO_(x)N_(y)/SiN_(x)背钝化的PERC太阳电池的lid也得到了改善,由对照组的1.83%下降到实验组的1.09%。
