The current global image descriptors are mostly obtained by using the local image features aggregation, which fail to take full account of the details of the image, resulting in the loss of the semant...
2018年1月,有关“南美洲新近系Orinoco三角洲大陆架及陆架边缘沉积演化”的研究成果刊发在美国地质学会国际重要期刊《Geological Society of America Bulletin》上。该文第一作者为中国地质大学资源学院副教授陈思博士。
As we mentioned in the preface of the last special issue (Suzuki et al., 2015), greater interests in submarine resources have been generated recently because many people have realized their high po...
Abstract: Chromium(VI) in the environment is of particular concern because it is toxic to both plants and animals, even at low concentrations. As a redox-sensitive element, the fate and toxicity of ch...
We present a comparison between XANES experiments and full multiple-scattering cal-culations at the magnesium K-edge for two pyroxenes, diopside and enstatite, for which Mg atoms are only in the M1 si...
The coordination environments of Ti in two fully metamict zirconolite samples and two partially metamict titanite samples were determined using high-resolution, X-ray absorp- tion near-edge structur...
The coordination environment of Ti in eight Ti-bearing glasses of the Na Si-Na,Ti y4 ;:join (NTS) and in six ATY2 glasses (A20Ti02.2Y02, with A =Na, K, ~r Rb andSi or Ge) was determined using high-re...
Si K- and L-edge X-ray absorption near-edge structure (XANES) of SiOz-PzOs and NazO-SiOz-PzOs glasses containing PzOsabove 30mol%wereinvestigated using synchro-tron radiation. BothSiK-and L-edge spect...
The acid hydrolysis products of trioctahedral fluorohectorite and phlogopite have been investigated by XRD, MAS NMR spectroscopy and nitrogen BET surface area analysis in an effort to assess the relat...
This paper compares the results of 27Al nuclear magnetic resonance spectroscopy (NMR) and Al-K-edge X-ray Absorption Near Edge Structure (XANES) of natural imogolite and allophanes and some crystallin...
Crystal growth theory was applied to describe edge sites of phyllosilicates. Three face configurations were found to exist. One face has one tetrahedral site per tetrahedral sheet and two octahedral o...
