Under the current seismic design code,ANSYS software of three-dimensional finite element is used to make a modal analysis of a 33-storey symmetrical twin-towers connection structure and the dynamic properties of the structure.

Based on the strain energy model presented by Sun-Zhang and the energy conversion and energy conservation,a new semicontinuum model is presented to calculate the nature frequency of a nanoscaled clamped-clamped silicon beam.

With technics mineralogy,the technology flowsheets of lead-first zinc-second flotation and zinc raw-concentrate regrinding were studied and confirmed by the characteristic analysis of intergrowth and single separation degree detection of synthesizing open-circuit experiment.

The existence of fine intergrowth of low Fe epidote and clinoepidote in the glaucophane schist from Mulan Mountain, Hubei province has been confirmed by the analytical data from electron probe microanalysis (EPMA) and optical microscopic (OM) analysis.

Many research and analysis indicate that the main reason affecting the grade of copper concentrate is the increase of intergrowth of impurities such as pyrite and quartz with copper minerals.

Development of Merrifield resin in solid phase organic synthesis is reviewed,which includes applications of various linkers with Merrifield resin and applications in organic synthesis.

The linker plays a crucial role in solid-phase synthesis.

The status of Cr-based alloy used as interconnect in solid oxide fuel cell(SOFC)was mainly reviewed in this paper.

In the planar design of intermediate temperature solid oxide fuel cell (ITSOFC), a metallic interconnect is used to separate the single cells.

The results show that STS444 alloy is not suitable for SOFC interconnect materials because the formation of volatilizing MoO3 on the oxidation film results in the loosening of oxidation film.
