In this paper, for stainless steel (0Crl8Ni9Ti), several common oxides and halides, namely SiO_2, Cr_2O_3, CaF_2, TiO_2 B_2O_3, etc, are taken as basic activating flux. On this basis, the composition uniform design method is employed to develop A-TIG activating flux.
For the low weld penetration in conventional TIG welding of aluminium alloy, several common oxides and halides,namely SiO2,Al2O3,MgO,TiO2,NaCl, CaF2, etc, are taken as basic activating fluxes to investigate their effects on the weld penetration of aluminium alloy .
In the experiment, the deposited metal of the GBE310-16(A402) stainless steel rested electrode is taken as basic, the content of nickel and chromium is changed and some rare-earth oxide is added in the coating of some electrode These deposited metals with different compositions are tested under super-temperature(13 80℃ and 1280℃ )by oxidation and sulphidizatioa The curve of weight-loss ratio to time is mede by weight-loss method.
The other 104 rats were made into models of immediate streptozotocin-diabetes mellitus by using intraperitoneal injection of streptozotocin with the dose of 60 mg/kg, and then the rat models were injected with long-acting insulin (4 UAg) from the 24~(th) hour after model establishment once every other day, which was taken as basic insulin to maintain life.
The earthquake catalog with the minimum completeness magnitude of ML = 1.7 during the period from 1970 to 1976 has been used as basic data for the research on time variations of seismicity rate in four subregions in source area (aftershock area) and its surroundings before the July 28,1976 great Tangshan earthquake in China.
And one language class culture as a basis for training students in good quality, and enhance the learning ability of students have irreplaceable important role. Unlike ordinary high school language teaching and vocational high school language teaching materials, which embodies the specific educational concepts, and teaching content and teaching purposes is one of the fundamental elements for vocational education, but also improve the quality of teaching vocational high school foundation and prerequisite.
This paper presents an optimization method for evaluating safety index and location of checking point in structural reliability analysis. This is a more exact method that may be used as a basis of comparison with the iterative procedure proposed by the Joint Committee on Structural Safety.
The concetration of free-A_g~*is controlled by addition of solutionN H_3·H_2O—NH_4NO_3·Br′or/and Cl′still remain in solution vhile I′ is precipitated quantitatively (pH=9.8-10.2), I′and Br′are precipitatee quantitatively, while Cl′ is not at all (pH=8.6-87.)
coli tRNAPhes used as basic structures differ by efficiency of the binding and aminoacylation with the enzyme under study.
In this study, the adhesion strength of three epoxy resins, which are used as basic materials for epoxy molding compound (EMC) in microelectronics, to copper leadframe was determined using the peel test.
When the generalized displacements on the nodal circles are used as basic unknowns, the number of unknowns on a nodal circle is more than four.
In parts I and II of this series  it has been demonstrated that localized three centre and two centre bonds may be used as basic functions for molecular orbital calculations on closed ("cage") and open ("basket") boron polyhedral molecules.
These surfactants are often used as basic components of shampoos and foam bath preparations.
In this report inulin was adapted to absorb C3 complement fromnormal human sera. Since then C3-inulin complex has been used for thepreparation of anti-C3 serum. The immunization procedure was based uponthe fact that living BCG was first inoculated for the purpose of activa-ting the immune system. After the initial activation, 2 injections of C3-inulin complex with complete Freund adjuvant were made subcutaneously,intramuscularly and intra-glandularly on multiple sites of the rabbit.By means of this method, we...
In this report inulin was adapted to absorb C3 complement fromnormal human sera. Since then C3-inulin complex has been used for thepreparation of anti-C3 serum. The immunization procedure was based uponthe fact that living BCG was first inoculated for the purpose of activa-ting the immune system. After the initial activation, 2 injections of C3-inulin complex with complete Freund adjuvant were made subcutaneously,intramuscularly and intra-glandularly on multiple sites of the rabbit.By means of this method, we found that serum titer was much higher,time interval much shortened, and testing material much saved.
