Solid oxide fuel cells （SOFCs） offer high energy conversion, low noise, low polluta.t emission, a.d low processing cost. Despite ma.y a.va.ta.es, SOFCs fa.e a.ma.or cha.lenge in competing with other types of fuel cells beca.se of their high opera.ing tempera.ure. The necessity to reduce the opera.iona. tempera.ure of SOFCs ha. led to the development of resea.ch into the ma.eria.s a.d fa.rica.ion technology of fuel cells. The use of composite ca.hodes significa.tly reduces the ca.hode pola.iza.ion resista.ce a.d expa.ds the triple pha.e bounda.y a.ea.a.a.la.le for oxygen reduction. Powder prepa.a.ion a.d composite ca.hode fa.rica.ion a.so a.fect the overa.l performa.ce of composite ca.hodes a.d fuel cells. a.ong ma.y types of ca.hode ma.eria.s, la.tha.um-ba.ed ma.eria.s such a. la.tha.um strontium coba.t ferrite （La._xSrxCOl_yFey03_~） ha.e recently been discovered to offer grea. compa.ibility with ceria.ba.ed electrolytes in performing a. composite ca.hode ma.eria.s for intermedia.e- to low-tempera.ure SOFCs （IT-LTSOFCs）.

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.

a.conta.t problem for a. infinitely long hollow cylinder is considered. The cylinder is compressed by a. outer rigid ring with a.circula. profile. The ma.eria. of the cylinder is linea.ly ela.tic a.d isotropic. The extent of the conta.t region a.d the pressure distribution a.e sought. Governing equa.ions of the ela.ticity theory for the a.isymmetric problem in cylindrica. coordina.es a.e solved by Fourier tra.sforms a.d genera. expressions for the displa.ements a.e obta.ned. Using the bounda.y conditions, the formula.ion is reduced to a.singula. integra. equa.ion. This equa.ion is solved by using the Ga.ssia. qua.ra.ure. Then the pressure distribution on the conta.t region is determined. Numerica. results for the conta.t pressure a.d the dista.ce cha.a.terizing the conta.t a.ea.a.e given in gra.hica. form.

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.
