Mg-9wt%Li-2wt%Zn alloy was prepared and studied in th.s article. Th. addition of Ca to th. alloy from 0.1wt% to 1wt% can refine th. α-Mg and th. best effect of refinement occurs wh.n Ca content is 0.4wt%-0.5wt%. Th. billets can be rolled to th.n sh.ets at room temperature, from wh.ch.it is obvious th.t th. addition of Ca improves alloys ormalin. wh.le it decreases with.th. excess addition of Ca. Th. results also sh.w th.t th. ultimate tensile strength.（UTS） and yield strength.（YS） of th. alloy with.lwt% Ca may rise by 28% and 25%, respectively, h.wever, th. elongation decreases. It is clarified th.t th. adsorption of proper Ca on th. grain boundaries refines α-Mg and improves th. tensile properties, but th. presence of excess Ca and stable Ca2Mg6Zn3ph.se worsens th. elongation.

Th.s paper deals with.th. design, construction and performance evaluation procedure of a solar tunnel dryer in drying fish. A 12 meter long and 2 meter width.h.lf-circled tunnel was designed and constructed to dry about 50-100 kg of fresh.y h.rvested fish.s per batch. Th. h.lf of th. tunnel base was used as th. flat plate air h.ating solar collector and th. remaining h.lf as a dryer. Th. drying air was forced from th. collector region (north.side) to th. drying region (south.side) of th. h.lf circled tunnel wh.re th. product is to be dried. Th. drying temperature could be easily raised by some 5-30 ℃ above th. ambient temperature inside th. tunnel at an air velocity of approximately 0.2 m/sec. Th. test was conducted with.51.5 kg fresh.y h.rvested sardines (h.lf-load) with.initial moisture content of 66.5% (wet-basis) to analyze th. performance of th. dryer. Th. fish.s were dried to a final average moisture content of 15.5% (wet-basis) with.n th.ee days (30 h.urs). It was possible to reach.th. moisture content level for safe storage with.n less th.n th.ee days (30 h.s) with.solar tunnel dryer and 7 days in open air natural sun drying. Th. improvement in th. quality of fish.s in terms of color, brigh.ness, flavor, and taste and food value was distinctly recognized.

抑制差减杂交克隆肺泡发育上游调节基因

肺泡是肺进行气体交换的基本功能单位,但对其发生、发育及调节机制的认识还十分有限。为克隆调节肺泡发生的新基因,我们利用抑制差减杂交技术,以与肺泡发生密切相关的原始肺泡期和肺泡期的小鼠肺为材料,分别相对于肺泡成熟期鼠肺组织构建了两个抑制差减杂交cDNA文库,从中筛选出118个肺泡发生的上游因子。这些基因涉及机体生长发育过程及其调节的多个方面。如可增加内皮细胞渗透性而参与肺血管系统的发生和重建的瞬时受体蛋白(TRPC4),通过刺激平滑肌生长促进肺泡壁毛细血管的发育凝集素(Lgalsl)等。特别是神经元蛋白3．1(亦称P311),因其同时特异表达于原始肺泡期和肺泡期而引起我们的注意。实时PCR进一步显示,P311表达于肺发育的全过程,但表达高峰仅出现于肺泡发育相关阶段,而在成熟肺组织中降至最低点。提示P311可能与肺泡形成密切相关。

对语言的关注是后期海德格尔思想的一个基本主题。语言不应当是私人性的,一个思想者不可能脱离其语言,但他必须脱离他的话语,而问自己:谁在说话?并去倾听语言本身的言说。与之有关,本文涉及到博德尔对海德格尔关于赫拉克利特的逻各斯、以及阿那克西曼德、毕达哥拉斯、巴门尼德等人有关思想的解释的解释。从这里,我们看到,海德格尔将本源的语言看成是纯粹的语言,而博德尔则进一步将这种语言理解为智慧。
