The paper studied the scavenging active oxygen radicals of brown pigment from chestnut shell. The results showed that the brown pigment had scavenging effects on hydroxyl radical, superoxide anion radical and aliphatic radicals on lipid-peroxidation. In the range of test concentration, the maximum scavenging or inhibition rate of the brown pigment to hydroxyl radical generated by Fenton reaction, superoxide anion radical generated by illuminating riboflavin system and linoleic acid auto-oxidation was 83.0%, 82.1% and 88.5% respectively.

The assembly of journal and plain bearing liner space is too little, force of organic still oil pressure is small it is the crucial index that affects lubricant result, make lubricate because of lacking engine oil between crankshaft and plain bearing liner and bite dead invalidation, include to be pulled badly, lack lube, layer of alloy of dry attrition generation is fused, grind sliding surface to did not maintain the oily film of certain ply, and all sorts of local overload exhaustion are destroyed, cavitation erosion and V form are destroyed etc, through technology of him director diesel locomotive old experience reachs the analysis of pair of its breakdown reasons, put forward precautionary measures especially. As a result of,the burns caustic mechanism plain bearing liner to burn caustic mechanism of 1 plain bearing liner is the lube film burst between journal and plain bearing liner, cause plain bearing liner and crankshaft generation clash, below high temperature, high pressure and high rotate speed, the wear-resisting alloy layer of plain bearing liner wears away prematurely or fuse, cause plain bearing liner and crankshaft to stick thereby bite, can make the steel back of plain bearing liner and Kong Zhong produces whirligig, inlet port is jammed, carry on the back by steel again with the friction of aperture causes high temperature to make plain bearing liner burned-out further, can cause bolt to break off, happen swing a malign accident that pounds cylinder body of bad internal-combustion engine.
轴颈和轴瓦的装配间隙太小,还有机油压力低是影响润滑效果的关键指标,使得曲轴和轴瓦之间因缺少机油润滑而咬死失效,包括严重拉伤,缺少润滑油,干摩擦产生合金层熔化,磨滑面没有保持一定厚度的油膜,以及各种局部过载疲惫破坏,气蚀和V形破坏等,通过本人主管内燃机车技术多年经验及对其故障原因的分析,特提出预防办法。1轴瓦的烧损机理轴瓦烧损的机理是由于轴颈和轴瓦之间的润滑油膜破裂,导致轴瓦和曲轴产生摩擦,在高温、高压和高转速下,轴瓦的耐磨合金层过早地磨损或熔化,从而引起轴瓦和曲轴粘咬,会使轴瓦的钢背和座孔中产生旋转运动,进油孔被堵塞,再由钢背和座孔的磨擦进一步引起高温使轴瓦烧坏,并会造成螺栓折断,发生甩出捣坏内燃机缸体的恶性事故。

Times higher than that of initial strain. Polysaccharides, such as barley flour, dextrin and soluble starch, were better carbon sources than monosaccharides and disaccharides, such as glucose and maltose, for cell growth of B subtilis ZJF-1A5 and β-glucanase production. Yeast extract was the best nitrogen source, the following was soybean flour.
糊精、大麦粉等多糖有利于B.subtilisZJF-1A5 β-葡聚糖酶的产生,葡萄糖、蔗糖等易利用性碳源不利于菌体生物量的积累和β-葡聚糖酶的产生,β-葡聚糖酶受分解代谢产物阻遏调节。B.subtilis ZJF-1A5 β-1,3-1,4-葡聚糖酶的产生与菌体生物量和菌体生长状态密切相关,提高发酵产酶水平的关键是提高菌体生物量和解除葡萄糖效应。

The oxidation-deoxidization between Al and ZrO2 or Y2O3 is one of the mechanisms of high temperature oxidation failure of TBCs. The failure under thermal shock results from the formation of cracks normal to the bond/top coat interface, due to the different coefficients of thermal expansion between bond coat and top coat and the temperature change.
底层与面层之间界面存在的部分Zro,或YZO3被A1还原生成Zr或Y,A1被氧化形成A1203的反应是热障涂层高温氧化失效的原因之一;热震失效的主要原因是由于底层与面层之间热膨胀系数的差异而产生的剪应力与喷涂时产生的内应力之和导致面层产生裂纹。

The primers and the detection programs have been used to detect the pathogens in the inoculated-diseased cucumber plants .The details are reported as follows: 1. By using the primers ITS1/ITS4, only Fusarium isolates could be amplified to produce a special fragment of 750bp. This product generated 480bp, 200bp and 100bp fragments after digested by restriction enzyme HinfⅠonly from the pathogen of Cucurbits Fusarium Wilt.
