Some SPR-LI neurons were also positive for TH. After administration of vasopressin, SPR-LI structures became denser, especially at levels of pyramidal decussation and area postrema . The dendrites of motor dorsal nucleus of X in the dorsal part of MVZ appeared thin and straight in morphology instead of curl and thick outlooks. These results implicate that some SPR-LI neurons might receive or regulate the cardiovascular stress information induced by vasopressin.③In PHA-L/FOS/TH triple-labeled experiments, seven kinds of immunohistochemical structures were found in MVZ. They were FOS-LI neurons, TH-LI neurons, PHA-L positive fibers, PHA-L positive fibers terminated on FOS-LI or TH-LI neurons, FOS/TH doublelabeled neurons, PHA-L positive fibers terminated on FOS/TH double-labeled neurons.

The bonding energy of the mixed covalent/metallic Ti-Al bond for the Ti-terminated Al/TiB_2 interface is larger than that of the polar covalent Al-B bond with partial ionic-like feature for the B-terminated interface. Metallic bond between Al atoms forms across the Al/AlB_2 interface, which results in weaker interfacial adhesion than that for the Al/TiB_2 interface. The interfacial energy for Al/TiB_2 depends on the interfacial chemical potential.

Al熔体中仅存在TiB_2粒子，而无多余溶质Ti时，α-Al在TiB_2粒子上异质形核产生的Al/TiB_2界面能大于α-Al从Al熔体中直接形核时的液-固界面能，不满足TiB_2粒子充当α-Al有效异质形核核心的能量条件，这从理论上解释了Al熔体内仅存在TiB_2粒子时无晶粒细化效果的实验现象。
