Electron capture between solar wind ions and neutral species has contributed to the understanding of X-ray production from solar system *** charge transfer and excitation processes in solar wind ions of He^(+)(1 s) colliding with Li(1 s^(2)2 s) atoms are studied by utilizing the full quantum-mechanical molecular-orbital close-coupling(QMOcc) method with impact energies of 0.003-2 keV *** of cross sections from single-and multi-configurational calculations for a selfconsistent field(ScF and McScF) process are carried *** show that the dominant reaction channels are He(1 s2 l ^(1,3) L)+Li^(+)(1 s^(2) ^(1) S).Good consistency is found among present total and state-selective charge transfer and excitation cross sections with other theoretical and experimental data in the same energy *** to the differences between coupling matrix elements in high-energy states,the charge transfer cross sections calculated from ScF and McScF split slightly as E> 0.4 keV *** Stueckelberg oscillations for charge transfer appear in the present *** addition,the differences of cross sections for electron excitation to Li(ls^(2)2 p) in the singlet/triplet molecular states with He+(1 s) are much smaller than those of charge transfer processes because of the similar energy gaps from Li(ls^(2)2 p) to the ground state in singlet/triplet states in the large R region.

AIM： To characterise the effect of energy restriction （ER） on liver lipid and primary metabolite profile by using metabolomic approach. We also investigated whether the effect of energy restriction can be further enhanced by modification of dietary protein source and calcium. METHODS： Liver metabolomic profile of lean and obese c57BI/6J mice （n = 10/group） were compared with two groups of weight-reduced mice. ER was performed on control diet and whey protein-based high-calcium diet （whey ＋ ca）. The metabolomic analyses were performed using the UPLc/MS based lipidomic platform and the HPLc/MS/MS based primary metabolite platform.RESULTS： ER on both diets significantly reduced hepatic lipid accumulation and lipid droplet size, while only whey ＋ ca diet significantly decreased blood glucose （P 〈 0.001） and serum insulin （P 〈 0.01）. In hepatic lipid species the biggest reduction was in the level of triacylglycerols and cerarnides while the level of cholesterol esters was significantly increased during ER. Interestingly, diacylglycerol to phospholipid ratio, an indicator of relative amount of diabetogenic diglyceride species, was increased in the control ER group, but decreased in the whey ＋ ca ER group （P 〈 0.001, vs obese）. ER on whey ＋ ca diet also totally reversed the obesity induced increase in the relative level of lipotoxic cerarnides （P 〈 0.001, vs obese; P 〉 0.05, vs lean）. These changes were accompanied with up-regulated TcA cycle and pentose phosphate pathway rnetabolites. cONcLUSION： ER-induced changes on hepatic rnetabolornic profile can be significantly affected by dietary protein source. The therapeutic potential of whey protein and calcium should be further studied.

沙棘种植前的整地是很重要的,这是因为沙棘果园要维持10～15年,是沙棘生产最盛的时期.整地的目的是消除杂草,准备好栽植穴,同时还要解决好土壤排水问题.至少能在种植前一年进行整地最好.因为沙棘为喜光植物,选址极为重要.在其自然分布区,沙棘通常形成枝条浓密的灌木丛.这些枝条位于灌丛中部,使有效光线在某位置上保留较长时间而不会立刻消失,并且它们形成了一个紧密、多刺的框架结构(Skogen,1972).种植地必须进行至少两次耕作,以除去多年生杂草.种植地以前的栽种历史会影响沙棘的生长,如除莠剂和农药的残留量、病害、虫害、杂草侵入、土壤条件等.整地作业是根据土壤类型及条件、前茬作物、植被、当地气候的差异而有所不同,沙质土用农具进行表层翻耕就行了.为了增加土壤有机质可通过加入适量的腐熟农家肥料,也可提前1～2年种植绿肥作物,并在播种前将其翻耕埋入地下进行熟化.而坚硬质地的土壤(淤泥和粘土),则应深耕且耙松.若存在阻碍排水的坚硬层,则需要深翻.整地技术包括以下几点:

Epitaxial n- and p-type Emitters for High Efficiency Solar cell concepts

引用

Journal of Energy and Power Engineering 2014年第8期8卷 1371-1377页

作者： Thomas Rachow Friedemann heinz Bemd Steinhauser Stefan Janz Stefan Reber Fraunhofer ISE (Institute for Solar Energy Systems) Freiburg D-79110 Germany

Reducing the module prices by increasing the efficiency of solar cells is one of the major challenges in today＇s photovoltaic research. The emitter formation by epitaxial growth offers a cost-efficient and faster alternative to the standard furnace diffusion process. The efficiency potential of epitaxial emitters 〉 22% has already been proven using a single wafer, low pressure, chemical vapour deposition tool. The purpose of this work is to show the potential of epitaxially grown emitters by APcVD （atmospheric pressure chemical vapour deposition） compared to diffused emitters. The APcVD formation of epitaxial emitters at 1,050 ~c can be realised as high throughput inline process and only takes 1-2 min, whereas the diffusion process using POcI3 takes up to 60 min. Simulations show an increase in voltage of AVoc = ＋10 mV and a reduction in saturation current ,1o of 30% for the epitaxial emitter. The lifetime experiments of solar cells with epitaxial emitter exhibit a diffusion length Leff〉 750μm and an emitter saturation current of Joe 〈 50 fA/cm2 on a planar 10 Ω2cm p-type FZ wafer. Another important aim of this work is to evaluate the limitations of epitaxial emitters due to high thermal budget, interface recombination and the change of reflective properties on textured wafers due to the deposition process. Solar cell efficiencies up to 18.4% on p-type and 20.0% on n-type wafers presented in this paper underline that the emitter epitaxy by APcVD is a competitive process for the emitter formation.

南大西洋地下阿尔必阶碳酸盐岩储层较具特征，但其在安哥拉南部的同位地层露头（本格拉[Benguela]和纳米贝fNamibe]盆地）却鲜有详细的沉积学研究。纳米贝盆地的碳酸盐岩常为米级厚地层，夹浅海相和陆架冲积扇硅质碎屑岩。底部碳酸盐岩地层可见由含牡蛎及棘皮动物化石的似核形石-球粒状砾屑颗粒灰岩（rud—grainstone）构成的碳酸盐岩丘（高度≤5米，直径1～2米）。凝块叠层石丘微相中可见红藻和微藻壳。该微相为海相，可与刚果和安哥拉的阿尔必阶碳酸盐岩中的藻-微生物-似核型石相比较。埋藏主导了成岩作用，重塑了碳酸盐岩的海相地球化学性质（可能除了镁的含量不符合这一推测）。由于重要的溶蚀和部分胶结作用，约22％的原生（粒间）和次生（微孔、溶模、孔洞、裂缝）孔隙是由重要的溶蚀作用和部分胶结作用而成。本文讨论了该地局部碳酸盐丘的两个沉积模型：（1）海侵滨岸海湾和浅水微生物礁的形成；和（2）海底地下泉水从冲积硅质碎屑岩注入滨岸下倾区。海相动物群与其他地方的海相阿尔必阶地层相似，部分保存的海水Mg地化标记都指示其为海侵。环境条件可能因硅质碎屑输入而变恶劣，盐度变化大且营养物含量逐渐升高，这些都与所观察到的微相一致。海底泉理论上可行，但考虑到欠缺明确的大气水标志，而且该地区碳酸氢盐含量高地下水存在的可能性不大，它实际上出现的可能性不大。本文对露头沉积模型进行了探讨，对以往的研究进行了梳理，提出了一套用于区分地下不同海相和非海相碳酸盐岩丘的标准。最重要的判断标准包括：（1）海相或陆相动物群；（2）沉积地球化学标志，特别是成岩过程中保存的Mg、Sr和δ13c及δ18O同位素；及（3）碳酸盐岩组构，如灌木状晶体，是热成因陆相丘体判别标志。丘体的地质体和矿物研究有时也可用做附加标准。这一套标准有助于南大西洋和其他裂谷盆地非常规碳酸盐岩储层勘探和开发策略的制定。
