	4	Mechanisms Involved in the Growth Promotion of Weaned Piglets by High-level Zinc Oxide显示文摘Dietary supplementation with high levels of zinc oxide (ZnO) is an effective method to prevent diarrhea and promote growth in weaned piglets.However,the mechanisms behind these beneficial effects are not well understood.Recent advances in this field indicated that the effects of ZnO on piglet growth are achieved through multiple regulatory pathways rather than a single pathway.This review focuses on recent advances in the effects of high level ZnO on:1)Zn status in weaned piglets;2)intestinal microbe flora regulation;3)intestinal structure and function;4)ion secretion in the intestine epithelium;5)intestinal immunology;and 6)secretion of brain-intestine peptides.ZnO appears to regulate the intestinal microflora and decreases the release of histamine to prevent diarrhea.ZnO also increases the expression of intestinal insulin-like growth factor-1 (IGF-1) and the IGF-1 receptor to ameliorate intestinal injury associated with weaning,and mediates secretion of brain-gut peptides to stimulate food intake,to promote the growth of piglets.Better understanding of the underlying mechanisms should inspire us to supplement the diet for weaned piglets with ZnO and investigate new approaches to prevent diarrhea and enhance growth.

	5	HYDROGEN EFFECT ON DEFORMATION BEHMIOR OF TITANIUM ALLOY AT HIGH TEMPERATURE显示文摘The effect of hydrogen on the deformation behavior of three typical kinds of titanium alloys, pure Ti, Ti-6Al-4V and Ti-15V-3Cr-3Al-3Sn (Ti-15-3), at high temperature has been investigated by short time creep test. XRD and TEM techniques are used to examine the changes in their microstructures. The results show that deformation rutes of pure Ti and Ti-6Al-4V alloy can be greatly increased by hydorgen charping due to an increase of β phase volume in their microstructures. β→α transformation is found to occur in unchanged Ti-15-3 alloy during creep process. The addition of 0. 73wt% hydrogen can completely inhibit the deformation-induced transformation and strengthen the metastable β phase in Ti-15-3 alloy, resulting in a dramatic decrease of deformation rate of this alloy at 700° C.
