Further studies show that the open porosity of 3 days and 28 days of harden mortar added GCL1-D is 28% and 21%,which is lower than that of blank. Harden mortar added GCL1-D has more pores smaller than 0.015mm,fewer pores larger than 0.065mm,and the largest pore diameter is 1.05mm,the most probable pore diameter is only 26% of that of blank.
The results show that only a few Cr23C6 second phases precipitate in austenite grain boundary and inside austenite grains after direct aging,while after strain aging a lot of Cr23C6 particles precipitate along some given directions inside austenite grains. These Cr23C6 particles' directional precipitation strengthening the austenite matrix and improves the reversibility of stress-induced martensite.
A degradation plasmid was drawn in Pseudomonas Stutzeri T7 using 1,2,4-trichlorobenzene (1,2,4-TCB) as the degradation bacteria of only carbon source. For studying the function of this plasmid, it was transformed in E.
The MRQP software is presently the only software in China that uses the mineral resources quantitative prediction method, is independent of the DOS environment, does not rely on other softwares such as MapGIS and ArcInfo and runs under the WINDOWS platform directly.
This implies that a system is algebraically integrable (i.e., its eigenvalue problem is explicitly solvable in quadratures) if and only if the differential Galois group is commutative for generic eigenvalues.
Then the ring of invariants ofG is a polynomial ring if and only ifG is generated by pseudoreflections and the pointwise stabilizer inG of any nontrivial subspace has a polynomial ring of invariants.
TheS-arithmetic group г is of typeFn, resp.FPn, if and only if for allp inS thep-adic completionGp of the corresponding algebraic groupG is of typeCn resp.CPn.
We show that they are induced by automorphisms ofG and that a surjective holomorphic self-map can be nonbijective only in the directions of the nilradical ofG.
We classify all instances when a parabolic subgroupP ofG acts on its unipotent radicalPu, or onpu, the Lie algebra ofPu, with only a finite number of orbits.
