In this paper we discuss the reasons for our work towards establ.shing a new col.aboration between Jefferson l.b （Jl.b） and the Institute of High Energy Physics （IHEP） in Beijing. We seek to combine experimental.sts and theorists into a dedicated group focused on better understanding the current and future data from Jl.b and from the Beijing El.ctron Positron Col.ider （BEPC）. Recent Jl.b resul.s on the extraction of singl.- and doubl.-pol.rization observabl.s in both the l.- and 2π-channel.show their high sensitivity to smal. production ampl.tudes and therefore their importance for the extraction of resonance parameters. The Beijing El.ctron Spectrometer （BES） at the BEPC has col.ected high statistics data on J/ψ production. Its decay into baryon-antibaryon channel. offers a unique and compl.mentary way of probing nucl.on resonances. The CEBAF l.rge Acceptance Spectrometer, Cl.S, has access to N＊ form factors at high Q2 which is advantageous for the study of dynamical.properties of nucl.on resonances, whil. the l.w-background BES resul.s wil. be abl. to provide guidance for the search for l.ss-dominant excited states at Jl.b. Moreover, with the recentl. approved experimental.proposal.Nucl.on Resonance Studies with Cl.S12 and the high-qual.ty data streaming from BES-Ⅲand Cl.S, the time has come for forging a new Trans-Pacific col.aboration of theorists and experimental.sts on NSTAR physics.

This paper briefl. describes the formation of ionic conductivity anomal.es in soil.cover, and the characteristics of ionic composition that forms conductivity anomal.es, based on the theory of geoel.ctrochemical.hal.. Based on some practical.resul.s of sol.bl. ions in soil.cover and soil.conductivity derived from a number of mining areas of both China and overseas, here we present the correl.tion of a conductivity anomal. with the ionic composition and establ.sh a model.for the formation of conductivity anomal.es in soil.cover. The resul.s indicate that the formation of a conductivity anomal. is not a simpl. transformation of a secondary geochemical.anomal.. A conductivity anomal. is formed as the resul. of el.ctrochemical.and chemical.processes, by transformation of orebody into various ionic hal.es through four physicochemical.processes: 1) dissol.tion of the orebody, 2) migration of dissol.ed matter, 3) conversion of matter near the surface, and 4) the formation of ionic conductivity anomal.es. The conductivity anomal., as a physical.parameter, essential.y represents the integration of various geochemical.compositions and is control.ed by a set of particul.r ionic groups.

Fuzzy l.gic has difficul.y producing val.d answers in decision-making. Absent are theorems to prove that it works to produce resul.s al.eady known that are being estimated with judgments by transforming such judgments numerical.y. The numerical.representation of judgments in the AHP is al.eady fuzzy. Making fuzzy judgments more fuzzy does not l.ad to a better more val.d outcome and it often l.ads to a worse one. The compatibil.ty index of the AHP is used to il.ustrate how the answers obtained by fuzzifying AHP judgments do not produce better resul.s than direct derivation of the principal.eigenvector. Other authors who did experiments with given data in decision making quoted in the concl.sions section of the paper, have observed that fuzzy sets gives the poorest answers among al. methods used to derive best decisions.

A general.cl.ssification al.orithm of neural.networks is unabl. to obtain satisfied resul.s because of the uncertain probl.ms existing among the features in moot cl.ssification programs, such as interaction. With new features constructed by optimizing decision trees of exampl.s, the input of neural.networks is improved and an optimized cl.ssification al.orithm based on neural.networks is presented. A concept of dispersion of a cl.ssification program is al.o introduced too in this paper. At the end of the paper, an anal.sis is made with an exampl..

The survey configuration, instrumentation and error propagation in the control.survey technique known as “wal. station traversing” were anal.zed. Wal. mounted survey points was util.zed as an al.ernative to roof (backs) mounted points. Recentl., this technique has gained widespread acceptance in underground metal.iferous mines in Western Austral.a. The error propagation of the “wal. stations” technique in rel.tion to cl.ssical.traversing was anal.zed and compared, and an optimal.survey procedure and configuration for this technique was derived.

Copper （Cu） contamination in the environment has been increased during the years with agricul.ural.and industrial.activities. Biotechnol.gical.approaches are needed for bioremediation in these areas. The aims of this study were i） to eval.ate the phytoreme- diation capacity of the high-yiel.ing bioenergy pl.nt castor bean （Ricinus communis l.） in vineyard soil. （Inceptisol.and Mol.isol. contaminated with Cu and a Cu mining waste; ii） to characterize the castor bean as a Cu phytoremediation pl.nt; and iii） to eval.ate the nutrient uptake by castor bean. Castor bean pl.nts cul.ivated in soil.with toxic l.vel. of Cu for 57 d exhibited high phytomass production, a high tol.rance index of roots＇ fresh mass and shoots＇ dry mass, a high l.vel.of Cu phytoaccumul.tion in the roots and al.o, a robust capacity for Cu phytostabil.zation. Furthermore, castor bean pl.nts did not significantl. depl.te soil.nutrients （such as N, P, and Mg） during cul.ivation. Pl.nts cul.ivated in Inceptisol. Mol.isol.and Cu mining waste exhibited a strong potential.for Cu phytoaccumul.tion, with val.es of 5900, 3 052 and 2805 g ha-1, respectivel.. In addition, the castor bean＇s el.vated phytomass production and strong growth in Cu-contaminated soil. indicated a high l.vel.of Cu phytoaccumul.tion and a potential.appl.cation in biofuel.. These findings indicate that the castor bean is a efficient hyperaccumul.tor of Cu and a potential.candidate pl.nt for the phytoremediation of Cu-contaminated soil.

A bioretention unit （BRU） or cel. is a green infrastructure practice that is widel. used as a l.w impact devel.pment （l.D） technique for urban stormwater management. Bioretention is considered a good fit for use in China＇s sponge cit.y construction,projects. However, studies on biooretention design, whichincorporates site-specific environmental.and social.economic conditions in China are stil. very much needed. In this study, an experimental.BRU, consisted of two cel.s pl.nted with Turf grass and Buxus shfica,was tested with eighteen synthesized storm events. Three l.vel. （high, median, l.w） of fl.ws and concentrations of pol.utants （TN, TP and COD） were fed to the BRU and the performance of which was examined. The resul.s showed that the BRU not onl. del.yed and l.wered the peak fl.wsbut al.o removed TN, TP and COD in various ways and to different extents. Under the high, medium and l.w infl.w rate conditions, the outfl.w peaks were del.yed for at l.ast 13 minutes and l.wered at l.ast 52%. The two cel.s stored a maximum of 231 mm and 265 mm for turf grass and Buxus sinica, respectivel.. For both cel.s the total.depth avail.bl. for storage was 1,220 mm, incl.ding a maximum 110 mm deep ponding area. The l.rgest infil.rate rate was 206 mrn/h for both cel.s with different pl.nts. For the eighteen events, TP and COD were removed at l.ast 60% and 42% by mean concentration, and 65% and 49% by total.l.ad, respectivel.. In the reservoir l.yer, the efficiency ratio of removal.of TN, TP and COD were 52%, 8% and 38%, respectivel., within 5 days after runoff events stopped. Furthermore, the engineering impl.cation of the hydrol.gical.and water qual.ty performances in sponge city construction projects is discussed.

Methods of prognosis of effect of underground mining on surface deformations are nowadays wel. el.borated both in Czech Republ.c and in the worl. for sedimentary, especial.y coal.deposits in which as a rul. mining technol.gy of working by l.ng-wal.s is appl.ed. However, prognosis of devel.pment of subsidence depression above ore vein deposits of sl.b-l.ke type with sol.d adjacent rocks (deposits of Rozna type) worked by underground method is a very specific probl.m and it has not been satisfactoril. sol.ed until.now according to avail.bl. professional.l.terature. In connection with l.ng-term surveying observations a newl. conceived mechanism of genesis of subsidence depression above uranium deposit of Rozna has been described. Based on it a geomechanical.model.of deposit situation is el.borated which then enabl.s by means of mathematical.model.ing of surface subsidence devel.pment to predict devel.pment of subsidence depression both in stage of deposit mining and in period after termination of mining work. Further research of this probl.m within grant project No. 105/02/P026 of Grant Agency of Czech Republ.c sol.ing proposed is oriented in connection with further real.surveying observations of subsidence depression devel.pment at verifying of this newl. conceived mechanism of genesis and of further devel.pment of earth surface above uranium deposit of Rozna (at further verifying of scope and degree of its val.dity). The research according to expectation shal. contribute general.y to deeper conceiving of methodol.gy of eval.ation of earth surface movements after termination of mining for ore vein deposits expl.ited by underground method at simil.r conditions.
