有二句话实在不会翻译了，请求各位帮忙了。？ 个人做了一些调整： 1，We have proposed a simple, rapid and versatile preconcentration technique, based on collecting trace analytes on a solvent-soluble filter and dissolving the filter and the analytes collected on it in a small volume of solvent 。 我们已提出一个简单、快速、多功能的预富集技术，该技术基于用一个溶剂 可溶的 滤纸收集微量分析物，以少量溶剂溶解滤纸及滤纸上聚集的被测物。 2，If the counter cation is excessively hydrophobic, not only the analyte but also the free reagent added to convert the analyte into a collectable form is retained on the filter, sometimes rendering the collection by filtration time consuming。 如果反荷阳离子异常疏水，那么被测物以及被添加用于将分析物转化为可聚集形态的游离 试剂 都会存留在滤纸上，因此有时会通过长时间过滤来形成聚集物。查看更多8个回答 . 2人已关注
aspen RPLUG 的fortran动力学子程序 纠错？ 这是我仿照论坛上的示例修改的子程序，请高手帮忙看一下，从语法上看看有没什么错误，多谢！编译后无法运行。 示例文件在这里 https://bbs.mahoupao.net/forum.php?mod=viewthread&tid=76210 C User Kinetics Subroutine for Urea synthensis, 2NH3+CO2=CARB; CARB=UREA+H2O C SUBROUTINE USURA (SOUT, NSUBS, IDXSUB, ITYPE, NINT, 2 INT, NREAL, REAL, IDS, NPO, 3 NBOPST, NIWORK, IWORK, NWORK, WORK, 4 NC, NR, STOIC, RATES, FLUXM, 5 FLUXS, XCURR, NTCAT, RATCAT, NTSSAT, 6 RATSSA, KCALL, KFAIL, KFLASH, NCOMP, 7 IDX, Y, X, X1, X2, 8 NRALL, RATALL, NUSERV, USERV, NINTR, 9 INTR, NREALR, REALR, NIWR, IWR, 1 NWR, WR) C IMPLICIT NONE C C DECLARE VARIABLES USED IN DIMENSIONING C INTEGER NSUBS, NINT, NPO, NIWORK,NWORK, + NC, NR, NTCAT, NTSSAT,NCOMP, + NRALL, NUSERV,NINTR, NREALR,NIWR, + NWR C #include "pputl_ppglob.cmn" #include "ppexec_user.cmn" EQUIVALENCE (RMISS, USER_RUMISS) EQUIVALENCE (IMISS, USER_IUMISS) C C C C C.....RCSTR... #include "rcst_rcstri.cmn" #include "rxn_rcstrr.cmn" C C.....RPLUG... #include "rplg_rplugi.cmn" #include "rplg_rplugr.cmn" EQUIVALENCE (XLEN, RPLUGR_UXLONG) EQUIVALENCE (DIAM, RPLUGR_UDIAM) C C.....RBATCH... #include "rbtc_rbati.cmn" #include "rbtc_rbatr.cmn" C C.....PRES-RELIEF... #include "rbtc_presrr.cmn" C C.....REACTOR (OR PRES-RELIEF VESSEL) PROPERTIES... #include "rxn_rprops.cmn" EQUIVALENCE (TEMP, RPROPS_UTEMP) EQUIVALENCE (PRES, RPROPS_UPRES) EQUIVALENCE (VFRAC, RPROPS_UVFRAC) EQUIVALENCE (BETA, RPROPS_UBETA) EQUIVALENCE (VVAP, RPROPS_UVVAP) EQUIVALENCE (VLIQ, RPROPS_UVLIQ) EQUIVALENCE (VLIQS, RPROPS_UVLIQS) C #include "shs_stwork.cmn" EQUIVALENCE (MKBAS, STWORK_NDUM) EQUIVALENCE (MKPHAS, STWORK_NBLM) EQUIVALENCE (MTAPP, STWORK_NCOVAR) EQUIVALENCE (MKBASS, STWORK_NWR) EQUIVALENCE (MTAPPS, STWORK_NIWR) EQUIVALENCE (SSALT, STWORK_RDUM1) EQUIVALENCE (VSALT, STWORK_RDUM2) EQUIVALENCE (FSALT, STWORK_FFSALT) C #include "dms_ncomp.cmn" #include "dms_plex.cmn" EQUIVALENCE (IB(1), B(1)) C C DECLARE ARGUMENTS C INTEGER IDXSUB(NSUBS),ITYPE(NSUBS), INT(NINT), + IDS(2),NBOPST(6,NPO),IWORK(NIWORK), + IDX(NCOMP), INTR(NINTR), IWR(NIWR), + NREAL, KCALL, KFAIL, KFLASH,I REAL*8 SOUT(1), WORK(NWORK), + STOIC(NC,NSUBS,NR), RATES(5), + FLUXM(1), FLUXS(1), RATCAT(NTCAT), + RATSSA(NTSSAT), Y(NCOMP), + X(NCOMP), X1(NCOMP), X2(NCOMP) REAL*8 RATALL(NRALL),USERV(NUSERV), + REALR(NREALR),WR(NWR), XCURR C C C DECLARE LOCAL VARIABLES C INTEGER IMISS, MKBAS, MKPHAS,MTAPP, MKBASS, + MTAPPS,LMW REAL*8 REAL(NREAL), XL(7), B(1), RMISS, XLEN, + DIAM, TEMP, PRES, VFRAC, BETA, + VVAP, VLIQ, VLIQS, SSALT, VSALT, + FSALT, RTEMP, DENLIQ,KKA, KKB, + AREA, RTA, RTB, SUMR INTEGER XMW #include "dms_ipoff1.cmn" C C INITIALIZE RATES C C C STATEMENT FUNCTIONS FOLLOW C C C BEGIN EXECUTABLE CODE C XMW(I) = LMW + I C C SET PLEX OFFSETS C LMW = IPOFF1_IPOFF1(306) DO 100 I = 1, NC RATES(I) = 0D0 XL(I) = 0D0 100 CONTINUE C DO 101 I = 1, NCOMP XL(IDX(I)) = X(I) 101 CONTINUE C C The structure in the array SOUT is as follows: C C SOUT(1) - SOUT(NCC) : Component flowrates(kg-moles/sec) C SOUT(NCC+1) : Total flowrates(kg-moles/sec) C SOUT(NCC+2) : Temperature(K) C SOUT(NCC+3) : Pressure(N/SQM) C SOUT(NCC+4) : Mass enthalpy(J/KG) C SOUT(NCC+5) : Molar vapor fraction C SOUT(NCC+6) : Molar liquid fraction C SOUT(NCC+7) : Mass entropy(J/KG-K) C SOUT(NCC+8) : Mass density(KG/CUM) C SOUT(NCC+9) : Molecular Weight C C Details of this infomation can be found in the User Guide C on page 17-10 for 8.5-6 or Reference Manual Vol. 6, User Models C for Release 9.
