In this pa.er, the obta.ned experimenta. results concerning crea.ion of bulk elementa.y excita.ions （BEEs） in isotopica.ly pure liquid ^4He a. low tempera.ures -60 mK a.e discussed. Positive rotons＇（R^＋-rotons） crea.ion by a.pulsed hea.er wa. studied. Signa.s were recorded for the following qua.tum processes： qua.tum eva.ora.ion of ^4He-a.oms from the free liquid-helium surfa.e by the BEEs of the liquid helium-Ⅱ, a.d BEEs reflection from the free surfa.e ba.k into the bulk liquid. Typica. signa.s a.e shown, a.d ra.ios of signa. a.plitudes a.e eva.ua.ed. For long hea.er pulses from 5 to 10 μs, a.pea.a.ce of the second a.omic cloud consisting of eva.ora.ed ^4He-a.oms wa. observed in a.dition to the first a.omic cloud. It is thought tha. the first a.omic cloud of the eva.ora.ed helium a.oms consists of very fa.t ^4He-a.oms with energies ～35 K eva.ora.ed by positive rotons with the specia. energies ～17 K （～2ER～2×8.6 K with ER representing the roton minimum energy） corresponding to the third non-dispersive Za.ha.enko wa.e. The second cloud of slower ^4He-a.oms wa. crea.ed by surfa.e elementa.y excita.ions （SEEs or ripplons） possessing the specia. energies ～7.15 K representing the binding energy. It wa. a.sumed tha. such SEEs ca. be crea.ed by phonons incoming to the liquid surfa.e with specia. energies ～6.2 K corresponding to the first non-dispersive Za.ha.enko wa.e which ca. intera.t a. the liquid surfa.e with the sa.e phonons a.rea.y reflected from the surfa.e for long hea.er pulses. a.so, some pulsed-hea.er cha.a.teristics were studied in order to better understa.d the fea.ures of such hea.ers in low tempera.ure experiments.

The objective of this work wa. to investiga.e the effect of the a.mospheric dew point on the sintera.ility of a.-14.9Si-2.4Cu-0.55Mg by studying the sintering cha.a.ters obta.ned under va.ious a.mospheric dew points. The a.uminium a.loy powder wa. pressed into tensile specimens a.d subsequently sintered in a.nitrogen a.mosphere a. 560 ℃ for 60 min with va.ied a.mospheric dew points. The results show tha. a. the dew point decrea.ed, the sintered properties were improved. The a.mospheric dew point of -38.4 ℃ is sufficient to obta.n good sintering cha.a.ters a.d it is a.hieva.le in a.commercia. furna.e.

a.a.ytic expressions for speed, flux, microrota.ion, stress, a.d couple stress in a.micropola. fluid exhibiting a.stea.y, symmetric, a.d one-dimensiona. electro-osmotic flow in a.uniform cylindrica. microca.illa.y were derived under the constra.nt of the Debye-Hiickel a.proxima.ion, which is a.plica.le when the cross-sectiona. ra.ius of the microca.illa.y exceeds the Debye length, provided tha. the zeta.potentia. is sufficiently sma.l in ma.nitude. Since the a.icula.e pa.ticles in a.micropola. fluid ca. rota.e without tra.sla.ion, micropola.ity a.fects the fluid speed, fluid flux, a.d one of the two non-zero components of the stress tensor. The a.ia. speed in a.micropola. fluid intensifies when the ra.ius increa.es. The stress tensor is confined to the region nea. the wa.l of the mi- croca.illa.y, while the couple stress tensor is uniform a.ross the cross-section.

In the present study, a.gra.e of sta.nless steel （SS, 410） a.d copper pla.es were joined through diffusion bonding by using a.nickel interla.er a. tempera.ure ra.ge of 800-950℃. These were performed through pressing the specimens under a.pressure of 12 MPa.for 60 min under 1.33×10-2 Pa.（10-4 torr） va.uum. The microstructure a.d pha.e constitution nea. the diffusion bonding interfa.e of Cu/Ni a.d Ni/SS were studied by optica. microscopy （OM）, sca.ning electron microscopy （SEM）, X-ra. diffra.tion （XRD） a.d a. elementa. a.a.yses through energy dispersive spectrometry （EDS）. The results indica.ed tha. a. obvious diffusion zone wa. formed nea. both Cu/Ni a.d Ni/SS interfa.es during the va.uum diffusion bonding. The thickness of rea.tion la.er in both interfa.es wa. increa.ed with increa.ing process tempera.ure. The diffusion tra.sition region nea. the Cu/Ni a.d Ni/SS interfa.es consist of complete solid solution zone a.d va.ious pha.es ba.ed on （Fe, Ni）, （Fe, Cr, Ni） a.d （Fe, Cr）, respectively. From EDS results, three different mixtures of pha.es were distinguished in SS-Ni interfa.e. The a.tiva.ion energy a.d ra.e consta.t were determined for the growth of these rea.tion la.ers a.d the va.ues become ma.imum for the （γFe＋Cr＋αFe＋Cr）.pha.e mixture.
