1. SEM was used to observe its surface structure, while IR spectrum indicated that the polymer membrane has COOH and NH3 functional groups and displays character of the amphoteric ion.
2. IR spectrum indicated that the polymer membrane contains—COOH, —NH_3~ functional groups appearing characters of the amphoteric ion.
3. Both men were already familiar with Moloney and his group through their work with Seánó Riada and Ceoltóirí Cualann.
4. Their structures are testified by ultimate and analysis, IR and MS.
5. This type of correlation, which has been used in a slightlymodied form[z/(4πIR2)] to estimatemetal binding constants for catechol and acetohydroxamic acid (29), is rationalized by noting that charge-dense hard metals with high ionic potentials interact strongly with the hard oxygen atoms in siderophore moieties.
6. It could form crystal inclusion compound s with guest molecules benzene and quinoline in definite ratios.
合成了主体分子反式 9，1 0 二氢 9，1 0 二对甲苯基 9，1 0 菲二醇(1)，它可以和苯、喹啉形成晶体包结物，通过m p、IR、粉末XRD对它们进行了表征，通过1HNMR积分计算包结物主客体物质的量比分别为：n1∶n苯=3∶2 ；n1∶n喹啉=1∶1。
7. The SEM, XRD and FT-IR characterization verified the MFI structure of the zeolite and that Ti atoms were present in the framework lattice of zeolite. The effect of operation conditions in the hydrothermal process on the catalytic activity and selectivity of TS-1 was investigated.
8. If a difference appears in the IR spectra of the analyte and the standard, dissolve equal portions of the test specimen and the Reference Standard in equal volumes of a suitable solvent, evaporate the solution to dryness in similar containers under identical conditions, and repeat the test on the residues.
9. The statistics included college students killed in car accidents if the students had alcohol in the ir blood, even if the level was below the legal limit.
10. Meanwhile, for the first time, the contributions of the Pauli paramagentism, Landau diamagnetism, Larmor diamagnetism and Curie paramagnetism are distinguished by fitting the magnetization, and we obtained the proportion of Ir ions which do not participate the spin-dimerization.
11. In this paper, The influence of heat set and dyeing on the structure of PTT fiber was investigated by FT-IR, DSC, critical dissolution time. The influence of heat set on the dyeability of PTT fiber was discussed, too. Meanwhile, many experiments on the dyeing performance of PET fiber were carried out. The effect of different dyeing temperature on the uptake and visual color depth value and dyeing characteristics of different dyes with temperature increasing were discussed, and the influence of temperature on the dyeing depth were also evaluated when dyeing for PTT and PET fiber in the same dye bath condition. Especially the kinetics and thermodynamics of dyeing with disperse dyes were mainly studied.
