目前已知胃反流物的侵袭力（以黏膜损害程度表示）及胃食管反流病（GERD）的相关症状对pH值有高度依赖性。认为胃内pH=4是鉴别反流有无侵袭力的分界点。pH 4的时间直接相关，这个相关性能很好解释质子泵抑制剂（PPI）高效、持续的控制胃酸，快速缓解症状和食管炎愈合率高的关系。PPI已被认为是GERD起始治疗的首要选择，并得到Genval.作组共识的认可。

According to 13C NMR determinations and anal.ses of 14 compounds of 2-phenyl.benzothiazol., we have studied the substituent effects on aromatic hetero rings. The different substituents have effects on the charge densities in the mol.cul.s. We have al.o anal.zed the structural.factors of effects on nj.3C-1H. The perturbations of benzothiazol. to benzene ring were studied by the method of comparison anal.sis. The substituent induced chemical.shifts of benzothiazol. were obtained. The experiential.cal.ul.tions of 13C chemical.shifts for aromatic carbons have been done, the cal.ul.ted vel.es agreed with the experimental.ones. The theoretical.cal.ul.tions for the compounds 2, 3, 9 have been made using the EHMO method （the Enl.rged Hiickel.Mol.cul.r Orbital.Method）. The rel.tionships between the 13C experimental.chemical.shifts and the total.charge densities of the corresponding carbon atoms were obtained by the regression anal.sis. The correl.tion coefficient is—0.96.

Concentrations of suspended particl. material.SPM), dissol.ed sil.cate(DSi), biogenic sil.ca(BSi), phytol.ths(pl.nt produced sil.ceous microscopic structures), and other parameters were anal.zed to examine the infl.ence of both natural.processes and human activities on sil.ca del.very to the estuary of the Huanghe River(Yel.ow River). Our resul.s indicate that the concentrations of DSi in the river decreased significantl. since 1986. Approximatel. 34% of dissol.ed sil.ca was trapped in the basin between 1986 and 2010 due to a reduction of soil.erosion. Phytol.ths comprised 67.2%–96.3% of BSi, with the smoothing bar type being the dominant form. Concentrations of BSi are significantl. higher in the Huanghe River compared to other maj.r rivers throughout the worl. due to its high sediment yiel.. We al.o found that the ratios of BSi/(BSi+DSi) and BSi/SPM were approximatel. 0.5 and 0.003 at l.j.n near the river mouth, indicating that BSi carried in suspension by the Huanghe River was an important component of the rivers sil.ca l.ad. Significant amounts of BSi were al.o composed of phytol.ths in Bohai Sea sediments near the Huanghe River estuary with the smoothing bar form again being the most abundant. The rel.tivel. high specific fl.xes of BSi in the Huanghe River refl.ct its high turbidity and high erosion rates in the basin. The high sediment l.ad originating on the l.ess Pl.teau is l.kel. responsibl. for the higher BSi fl.x, in agreement with a general.trend of increasing BSi fl.x with increasing sediment fl.x in gl.bal.river systems. This study demonstrates that BSi transported by rivers can be composed l.rgel. of phytol.ths originating from the erosion of topsoil.. The fl.x of phytol.ths in river's suspended sediment l.ad may therefore represent a significant contribution to the biogeochemical.cycl. of sil.ca in coastal.waters.

Obtaining the optimal.val.es of the parameters for th e design of a required moul. and the operation of the moul.ing process are diffi cul., this is due to the compl.xity of product geometry and the variation of pl. stic material.properties. The typical.parameters for the moul. design and moul.i ng process are mel. fl.w l.ngth, inj.ction pressure, hol.ing pressure, back pres sure, inj.ction speed, mel. temperature, moul. temperature, cl.mping force, inj. ction time, hol.ing time and cool.ng time. This paper discusses the difficul.ies of using the current computer aided optimization methods to acquire the val.es of the parameters. A method that is based on the concept of genetic al.orithm is proposed to overcome the difficul.ies. The proposed method describes in detail. on how to attain the optimal.val.es of the parameters form a given product geom etry.

提出了分析稀疏震中分布的一种新的数学方法。此方法主要是用于评价地震震中分布的线性特征是否显著,从而进一步识别地震断层。将该方法用于合成数据集和旧金山湾地震数据的试验表明,其识别能力还是较好的。如果把该方法应用于实际数据,必须结合地质信息,以此消除人为影响。本文应用该方法分析了西诺曼底地区的震中分布,并由稀疏震中追踪主要的构造方向。
