2.Stress level is estimated at tens of MPa based on existing flow laws.
3.The performance can reach country profession standard ZBG33005-89.The style is thickness 0.1mm,Width 13,26,52mm,arbitrary length surface density>1.4g/cm 3,tensile strength>6.0MPa,elongation at brenk (lonitndinal)≥50%,volatile subtr a hend<0.5%,burning retardance.
4.For type B, the transmitting speed of LVD flash tube is 4~5 times higher than that of normal flash tube. In comparison with normal flash tube, the average ignition peak pressure of LVD flash tube increases about 10MPa.
5.The tests indicate that under the worst situation (assembled by 2 rows, 8 layers), the stress distribution of most part of frames is only at several MPa, displacement on frame is in the range of -0.01 ~ -0.02,maximal displacement on baffle-board is smaller than 0.15mm.
6.The experiment results indicated that the about98%object products of 2-and 4-nitro-m-xylene were obtainedrespectively from the columm top and the still pot when thepresure of the column top is about 0.002 MPa.
7.The increasing rate of plastic strength ( P s) of the grouts is slow, the early P s is lower, the later P s may be 1～2 MPa. After 18 th day, P s of the grouts may be some MPa by adjusting the content of cement, structural agent and viscosity of clay mud.
8.The results show that sealed pressure points in can be determined by removing artificial factors, sealed pressure and minimum horizontal prinlipal stress have good correlation in which few absolute errors arc over 2MPa except one absolute error reaches 2.9MPa.
9.The results indicate that the electric and magnetic stresses due to current are directed into the inner of metal. Specially, the calculating result shows that on the crack tip the magnetic stress directed into the metal can be up to the order of 1-102( MPa) when the current density arrives to the order of 103-104( A/mm2).
