氮化作用

Notch and groove were produced on fiber's surface by plasma's pHysical bump and corrasion, meanwhile oxygenic or nitrogenic radicals were also grafted on the surface. Through hydrolyzation, acetate fiber's surface will be denuded by cellulase enzyme. Surface of the fiber will be granulated and specific surface area will be enlarged by plasma and enzyme treatment, therefore obviously improve fiber's surface performance.

等离子体对纤维的物理撞击和表面刻蚀使纤维表面产生凹坑和沟槽，同时可在纤维材料表面引入含氧或含氮基团；而纤维素酶对纤维素的水解作用，促使纤维表面被剥蚀；等离子体与生物酶处理都能使纤维表面粗糙化，比表面积增加，使纤维的表面性能得到明显改善。

为了证实穹窿下器在脑内免疫调节系统中的作用，在本研究当中，应用了NADPH-d的组化方法、TUNEL末端标记法、扫描及透射电镜方法、免疫组织化学的荧光双标法及激光扫描共聚焦显微镜技术，来研究在腹腔内给予大肠杆菌内毒素后，脑内的一氧化氮合酶细胞的变化、室管膜细胞的凋亡、早期即刻基因c-fos的表达与星形胶质细胞之间的关系，以及穹窿下器与其它脑区相比较时的特异性改变。

ResuIt:1. JDD can significantly improve the digestive system symptoms and physical strength of CRF patients. It can also reduce the urine protein.plasma lipids,BUN and Scr notably.The total effective rate of treatment group is 86.67%,better than that of control group(P.05).2.The experiment revealed JDD can restrain the crescendo-developed mechanism of CRF,which is achieved by decreasing blood ET-1,plasma lipids,urine protein etc.lt also can lighten glomerular sclerosis,inhabit uriniferous tubule-interstitial fibrosis.

结果：1。降氮汤能明显改善消化道症状及体力等一般情况，显著降低尿蛋白，血脂和血Scr、BUN，其总有效率86.67％，显著优于尿毒清对照组(P＜0.05)。2，实验发现降氮汤可通过降低血ET-1、血脂、尿蛋白等途径抑制CRF的渐进性发展机制，减轻肾小球硬化和肾小管-间质纤维化，具有肾保护作用。

The compost of agricultural waste materials is the process that under the function of microorganism, the organic matter turn into well-rotted manure by the way of the organic matter being mineralized and humus and harmless.

农业废弃物的堆腐是在微生物作用下，通过发酵使有机物矿质化、腐殖化和无害化而变成腐熟肥料的过程，在微生物分解有机物的过程中，不但生成大量可被植物吸收利用的有效态氮、磷、钾化合物，而且又合成新的高分子有机物---腐殖质。
