    摘要： A tube 12 made of stainless steel is arranged in a thermal bath 13 and an AC current is supplied to the tube to apply an AC heat directly to the tube and a liquid sample contained therein. An AC temperature of the tube 12 is detected by a thermocouple 19. An amplitude of the AC heat, and a phase difference between the AC heat and the AC temperature are detected. The above measurement is performed for the vacant tube, the standard liquid sample containing tube and the liquid sample containing tube to derive amplitudes .DELTA.T.sub.c, .DELTA.T.sub.r and .DELTA.T.sub.s and phase differences .phi..sub.c, .phi..sub.r and .phi..sub.s. Then, a heat capacity .rho..sub.s .multidot.C.sub.s per a unit volume of the liquid sample is calculated from a following equation.rho..sub.s .multidot.C.sub.s =[{sin (.phi..sub.s)/.DELTA.T.sub.s -sin (.phi..sub.c)/.DELTA.T.sub.c }/{sin (.phi..sub.r)/.DELTA.T.sub.r -sin (.phi..sub.c)/.DELTA.T.sub.c }].rho..sub.rwherein C.sub.r and .rho..sub.r denote heat capacity and density of the standard liquid sample, respectively. In this manner, the heat capacity of the liquid sample can be measured precisely without being affected by heat leakage.

    摘要： Phenolic resin compositions comprising a polymeric substance having a phenolic OH group such as phenol resins, and a rubber having an epoxy group and an epoxy equivalent of 500 to 30,000 such as butadiene copolymers, acrylic copolymers, chloroprene copolymers and urethane copolymers are provided. These resin compositions exhibit improved properties having overcome the drawback of brittle properties intrinsic of conventional phenolic resins, and also exhibit cold resistance; hence they are used as molding materials, laminating materials, casting materials, binders, etc. Further, molding resin compositions having improved solvent-resistance and metal insert properties are provided.
