小麦盆栽试验中，土壤微生物量碳、氮的变化趋势类似，即在苗期迅速升高，到拔节期含量达到最高，以后逐渐降低直至收获。

Firstly, the dissertation chose the species of additives and decided the concentrations of addition. Then experiments had been carried out by using corn stover ensiled with those additives under ideal ensiling condition. After each storage and fermentation period, silage was removed from silo tin and analyzed for DM, pH, DM digestibility, NDF digestibility, organic acid composition and content, DM Recovery, silage composition, ammonia-N-to-total-N ratios of silage. Those results had been used to evaluate the effects of those additives on corn stover silage.

课题首先根据查阅的大量文献资料，确定要研究的添加剂种类和添加剂量，然后在玉米秸秆原料中添加所选的添加剂，在适宜的青贮条件下进行青贮饲料的调制试验，将经过一定发酵时间的青贮饲料开封后，通过测定玉米秸秆青贮饲料的干物率、pH值、有机酸含量及组成、干物质消失率、NDF瘤胃降解率、干物质回收率、青贮化学成分、氨态氮占总氮的比例等指标，这些测定分析结果用来确定不同添加剂对玉米秸秆青贮饲料质量的影响。

The pH value of silages was all lower than 4.0 and the ratio of ammonia nitrogen to total nitrogen was all lower than 5.0, which improved the quality that all the silages in experiment were good.

经不同切碎方式的各组青贮饲料的有机酸含量均无显著差异（P〉0.05），pH值均在4.0以下，而且氨态氮与总氮的质量比也均在5.0以下，达到了优质青贮饲料的标准，虽然各青贮饲料的粗蛋白、粗灰分和可溶性碳水化合物含量有显著差异（P〈0.05），但均为优质的青贮饲料。

Results showed that there were no evident effects of different mechanical processes on the organic acid content(P＞0.05). The pH value of silages was all lower than 4.0 and the ratio of ammonia nitrogen to total nitrogen was all lower than 5.0, which improved the quality that all the silages in experiment were good. Though the effects of three different mechanical processes on the CP, CA and WSC contents of silages were evident, the silages were all excellent.

经不同切碎方式的各组青贮饲料的有机酸含量均无显著差异(P＞0.05)，pH值均在4.0以下，而且氨态氮与总氮的质量比也均在5.0以下，达到了优质青贮饲料的标准，虽然各青贮饲料的粗蛋白、粗灰分和可溶性碳水化合物含量有显著差异(P＜0.05)，但均为优质的青贮饲料。

Treatment of corn stover silages with cellulase and lactobacillus had improved DM digestibility 8% and decreased VBN/TN 33%, butyric acid-to-total acid ratios 81%, NDF content 10%, ADF content 7%. That had approved their quality be improved obviously.

乳酸菌和纤维素酶的共同作用可以使玉米秸秆青贮料的干物质消失率提高8％，使氨态氮与总氮的比值降低33％，丁酸占总酸的比例降低81％，同时使NDF、ADF的含量分别降低10％和7％，说明玉米秸秆青贮料的质量明显改善。

Quantitatively, the optical density of NADPH-d positive neurons in all of the related nuclei was significantly increased in the BDL animals compared with controls. Since NO is thought to be able to increase the motilities of the gallbladder and the sphincter of Oddi in anesthelized rabbits, the elevation of NADPH-d and NOS reactivities is likely to magnify the excitatory effect on the extrahepatic biliary system for the purpose of depletion of the loitered bile juice from the jaundiced liver. These data may also have important implications for the altered state of circulatory, metabolic or regenerative responsiveness under pathological condition.

此现象一来可推测，肝脏在遭受胆管阻塞性黄胆的伤害后，其代谢、血液动态与温度调节作用势必改变、紊乱、甚至失功能，而感觉神经也势必会接受到大量的机械性、化学性、渗透性等感知讯息，所以感觉神经元将一氧化氮制造量提升，有助於感觉讯息的快速传报，以发挥回馈调控的效果；二来可表示，自主神经系统不论是交感或副交感神经，为了因应胆管阻塞所造成肝脏的病变，以增加一氧化氮的制造，意欲刺激肝外胆道系统，排空滞留在肝脏内或胆囊内的胆汁，而达到恢复肝脏内代谢、血液循环、胆汁流动等功能控制的恒定状态。
