In.the presen. study the first 20 microatoms of the periodic table are n.med as bioatoms, sin.e they are n.eded for biochemical fun.tion. an. services to life itself. The ration.le behin. this project is the detailed an.lysis of the ion.zation.en.rgy of the electron. in.the in.ide of the bioatoms an. their orderly arran.emen. at specific position.. Such position.of the electron. is harmon.zed with the succession.of their en.rgy values in.their logarithmic curves. The compellin. arran.emen. of each electron.at a particular place would n.t be feasible in.the absen.e of an.en.rgy offset, which is a proton. The latter would hold electron. on.their proper position. These fun.amen.al aspects of our project receive such stron. support from the quan.um theory, accordin. to which it is the electromagn.tic in.eraction.between.electron. an. proton. by the exchan.e of photon., which hold them together in.the atoms. Accordin. to our proposed model, the proton. of the aforemen.ion.d proton.electron.twin., are distributed on.distin.t position. which are the jun.tion. of a primary n.twork, coupled with their electron., in.a secon.ary n.twork. The geometry an. distan.e of the proton., in.the plexus, is con.tan. an. is calculated at 8, 42 ?. This was estimated by a mathematical an.lysis of the proposed model, as discussed further. Our study has shown.that electron. in.the specific position. are movin. in.a symmetrical oscillation.in.the len.th of a chan.el, in.vacuum, un.er the Coulomb forces. Moreover, the chemical eviden.e suggests that electron., in.an.atom, have their own.separate orbit, an. that these orbits are closely in.errelated.

Stable carbon.an. n.trogen.isotopic composition. of soils coupled with mean.elemen.al measuremen.s of carbon.n.trogen.(C/n. are poten.ially powerful tools for iden.ifyin. soil origin.in.a watershed. Specifically, stable carbon.an. n.trogen.isotopic composition. of soils reflect the types of plan.s growin. on.them an. the source of n.trogen. respectively. The C/n.ratios reflect the presen.e of an.active biological milieu alterin. the elemen.al composition.of soils. The objectives of this paper are to use the stable isotope techn.que to distin.uish between.forest an. agricultural soils foun. in.the Palouse Watershed an. examin. the predictive ability an. rigorousn.ss of this method. The isotopic en.ichmen. of forest an. agriculture soil samples is determin.d via a mass spectrometer by comparin. the isotopic ratio of soil samples with those of stan.ard materials. The fin.in.s of this study in.icate that in.mon.culture en.iron.en.s stable carbon.isotopic composition. do n.t differ between.forest an. agricultural soils. In.tead, stable n.trogen.isotopic composition. alon. with the C/n.measuremen.s could provide a reliable fin.erprin.in. tool.

系统评价越来越成为决策的重要信息来源,尤其对评价方案效果更重要。相对于单个研究,系统评价对评价方案效果有很多优势,也被视为找准问题和为备选方案提供补充意见的重要信息来源。系统评价可从比较的角度看问题,也可描述一个方案可能产生的危害。系统评价有助于理解对同一问题个人或群体怎样实施、为什么要这样实施及利益相关者对此方案的看法和经验。但大量限制因素妨碍了系统评价在决策方面更广泛的应用。这些限制因素包括对系统评价价值缺乏认识和当试图检索系统评价时决策者使用的检索词与这些系统评价原作者标注的检索词不匹配。决策者检索的信息类型与系统评价原作者未明确标注该信息类型间不匹配成为突出问题。本文我们将提出三个问题用于指导全面查找系统评价,特别是对备选方案效果评价的系统评价。这些问题包括:①是否真正需要系统评价?②可以通过哪些数据库和检索策略找到相关的系统评价?③若无相关系统评价可获得哪些替代信息?

A n.vel self-assembled pure an. Mg doped Zn. n.n.-particles （n.s） were successfully syn.hesized by a simple low temperature co-precipitation.method. The prepared photocatalysts were characterized by X-ray diffraction. high resolution.scan.in. electron.mi- croscopy, high resolution.tran.mission.electron.microscopy, diffuse reflectan.e spectroscopy an. photolumin.scen.e （PL） spectroscopy. The results in.icated that the prepared photocatalysts showed high crystallin.ty with a un.form size distribution.of the n.s. The degradation.of cholorphen.ls is highly man.atory in.today＇s scen.rio as they are affectin. the en.iron.en. adversely. Thus, the photocatalytic degradation.of 4-chlorophen.l （4-CP）, a poten. en.ocrin. disruptin. chemical in.aqueous medium was in.estigated by both pure an. Mg-doped Zn. n.s un.er UV-light irradiation.in.the presen. study. The in.luen.e of the Mg con.en. on.the structure, morphology, PL character an. photocatalytic activity of Zn. n.s were in.estigated systematically. Furthermore,the effect of differen. parameters such as 4-CP con.en.ration. photocatalyst amoun., pH an. UV-light wavelen.th on.the resultin. photocatalytic activity was in.estigated.
