structural formula
2.β=1.22×10~7 and the structural formula The electrode processes are described with the following steps: (1) complex formation of Sc~(3+) with Cup and DPG; (2) adsorption of the complex on the surface of the electrode;
3.The present paper deals with the preparation of 2-hydroxymethyl-cis-cyclohexylidene acetic acid(Ⅲ) and its lactone(Ⅱ) and also with the conformation of the modified structural formula Vc for the Mannich-Braun compound.
4.Supposing there is S≥2 , the linear indefinite equation in S variables refers to the following form: a1x1 + a2x2 +…+ ascs = n , in which ai (i = 1,2, …, s ) and n are given integral numbers, a1 a2… as ≠0. This paper provides a structural formula of integer solution for the above form by means of division algorithm of S variables a1,a2,… , as.
5.Bearing capacity of normal cross section, ductility, cracking load and failure characteristics of RLC were studied. The study result suggest that it is applicable of structural design criterion formula of common concrete for HSLC and then calculate formula for crack bending moment of rectangle cross section was revised.
6.Deducted from the structural state of Al2O3, B2O3 and SiO2 of the frit,an empirical formula is presented here to enable the calculation of weight loss due to acid corrosion (Wl). Consequently, the formula serves to pave the way to further lowering of the firing temperature(Tf) of enamel with ensured acid resistance.
7.The purpose of this article is to review some recent view point on eht structural relaxation of metallic glasses. Through the studies and analysis of internal friction in a-Pd80Si 20 during isothermal processes, the nonlinear dynamic feature of structural relaxation in a-Pd80Si20 is provied and a Semi-empirical formula of the vaJation of internal friction of metollic glass a-Pd80Si 20 during isothermal relaxation is presented.
8.By means of studying the structural dynamics optimization design that takes the displacement of physical measurement of structural response under motivated excitation as the target or constraint and utilizing the analytical method, the sensitivity computation formula of dynamic displacement response was derived and being successfully transplanted into the finite element program.
9.Taking the hydraulic engineering tunnel in jointed rockmass as an object of study, considering the combination of rockmass structural plane with the cavern arrangement, the paper derives the general formula for the over-excavation block volume calculation By the examination of the cavern top over-excavation block volume calculation for the exploration adit PD6 of a hydraulic engineering tunnel, it assesses the over-excavation block volume and its distribution Thus, it presents a certain basis for the excavation and solidification treatment of that horizontal tunnel
10.A mineral having the chemical formula of BaCe(CO3)2F newly found in China is called Hwanghoite and may be named from the structural point of view as barium-synchysite.
