With the aids of variational methods and delicate estimates, the existence of nontrivial solutions is obtained for elliptic equations with singular potential-△u-μ u/|x|2=|u|2*(s)-2u/|x|s+ λu,u∈H0 (1,2)(Ω)where Ωis an open bounded domain with smooth boundary,μ,λA are two positive parameters.
The existence of infinitely many solutions for the p Laplace Dirichlet problem is dealt with, - div (|u| p-2 u)=λ|u| q-2 u+μ|u| α-2 u,u∈W 1,p 0(Ω), when λ>0 or μ>0 , where Ω is an open bounded subset in R N and 1
The microwave properties of Ba(Mg_(1/3)Ta_(2/3))O_3 type ceramic materials were investigated by using the Hakki-Coleman opened resonator method. The results listed follow:BMT 系,ε=24.79, Qf=143000(10.10GHz),τf=0.0075×10~(-6)/℃;
③Digesting pLXSN-mB7-1 by enzyme XhoI and BamHI to gain the opened plasmid pLXSN-mB7-1 with ambly end and BamHI sticking end; Inserting IRES-mB7-2 gene fragment into it to gain the double expressing vector pLXSN-mB7-1-IRES-mB7-2;
An improved visualization device made of polymethyl methacrylate (PMMA) was used to study the 3D flow profile inside conical columns of a 10° opening angle packed with C18 phase.
Phthalides have primarily undergone two ESI CID pathways: side-chain cleavage with losses of alkenes and ring-opening with eliminations of H2O followed by losses of CO.
Compared with lactide ring-opening polycondensation (ROP), the direct melting polycondensation of LA and CL is more practicable and simple.
Transmission Electron Microscopy (TEM) images further verified the formation of MCM-48 with uniform cubic pore channel system having the pore opening diameter of about 25 ?.
The cationic ring-opening copolymerization of AMO with another oxetane-derived monomer, 3-(2-(2-(2-methoxyethylenoxy)ethylenoxy)ethylenoxy)-3'-methyloxetane (MEMO) was conducted in CH2Cl2 solution using BF3 · OEt2/1,4-butanediol as a co-initiator.
The results indicated that the activated carbon developed from sewage sludge (ACSS), which was mesoporous, possessed opened porous structures.
Generally, fundamental research on traditional mechanisms is enhanced; mechanism and creative design of products are closely combined; modern mechanism with advanced and new technology is opened up; and mechanism is promoted to modernization.
The lipid composition of the embryo leaflets forming a bud, or "treble clef", and that of fully opened leaves changed throughout the growth season.
By midsummer, the DGTS content decreased, dropping to zero in the fully opened leaves, and then increased again.
We have proposed that in our experiments the pore opened in a substate with lower permeability rather than in the "classic" state (Bodrova, M.
