Effects of ordinary silage and mixed silage on the Robinia pseudoacacia, Caragana and Amorpha fruticosa silage were studied by observing color, odor, texture, pH, organic acid composition and content, ammonia-N / total-N ratio, crude protein, neutral detergent fiber, acid detergent fiber and comparing their nutritive value before and after silaging. Results showed that silage quality of R.

对刺槐、柠条和紫穗槐进行了单独青贮和两两混合青贮，并从青贮饲料的色泽、气味、质地等感官品质，pH值、有机酸含量及组成、氨态氮／总氮比值这些发酵品质，以及粗蛋白、中性洗涤纤维和酸性洗涤纤维这些营养价值方面进行了分析评定。

NH3-N is convered in to nitrogen under the condition of anoxic, which is termed as nitrification.

生物脱氮是指利用微生物将含氮化合物中的氮转化为氮气，它分为硝化和反硝化两个过程。

However, when the concentration of nitrate was 21 mg/L, nitrite with the concentration of 106 mg/L has an approximative potential.

因而，利用亚硝态氮，尤其是硝态氮低浓度条件下，强化反硝化条件下河流沉积层中苯降解是可行的。

Compared the two factor showed that the yield and quality were affected evidently by nitrogenous the yield of Luyuan301 was single-apex changed with the increase of nitrogenous used. Furthermore, Jimai20 is more sensitive to nitrogenous than Luyuan301, the protein content and artifactitious quality were positively related to the nitrogenous.

两因素比较表明，作物产量和品质受氮素因子影响大，籽粒产量随施氮量的增加呈单峰曲线变化，且强筋小麦济麦20对氮素缺乏较鲁原301敏感，其蛋白质含量和加工品质与施氮量呈正相关关系。

The organic compounds like cyanine, macrocyclic azotic compound, azo-metal complex, metal chelate, benzoheterocycle dye, have been applied to recordable optical discs as the recording materials.

菁类、大环氮杂、偶氮、金属螯合物、苯并杂环等类的化合物已被作为光记录材料进行研究。

Results of nitrogen balan ce calculation indicated that nitrogen surplus Was primarily existed with Nmin at low nitrogen application rate,while Was primarily apparent loss at high nitrogen application rate treatments.

氮素平衡计算的结果表明，低施氮量时，氮素盈余以残留Nmin为主，高量施氮则以表观损失为主。

The 6- cyano-1, 1 (1, 3- dioxypropylidene)-7-(carbomethoxyl group- methyl - 5- oxo-Delt6 (8)- tetrahydrochysene indolizine and haloethane reacts with each other for ethylization with existence of alkali and organic solution with or without phase transversion catalyst, and produces mentioned product.

本发明在相转移催化剂或无相转移催化剂存在下，6-氰基-1，1-(1，3-亚丙二氧基)-7-(甲氧羰基-甲基-5-氧代-Δ6(8)-四氢中氮茚类化合物与卤代乙烷在碱和有机溶剂的存在下进行乙基化反应即得6-氰基-1，1-(1，3-亚丙二氧基)-7-1′-(烷氧羰基-丙基-5-氧代-Δ6(8)-四氢中氮茚类化合物。

The 6-nitro-2-benzothiazolyldiazoaminoazobenzene as a chromogenic reagent was synthesized and its color reaction with nickel has been investigated.

合成了显色剂6 硝基 2 苯并噻唑重氮氨基偶氮苯，并在TritonX 100表面活性剂存在下，研究了其与镍的显色反应。

It is shown from the assessment results that (1) both the TN and TP fluxes discharged from the Changjiang River to the Changjiang River estuary sea area increased continuedly, the DIN concentration in the sea areas increased continuedly, and the Si concentration decreased continuedly, which resulted in the significant changes in N/P/Si ratios;(2) the chlorophyll a concentration in the sea areas increased continuedly, and the significant changes in community structure of phytoplankton occurred;(3) the species and biomass of benthos declined greatly, and the bottom oxygen-poor water area increased significantly;(4) the range and occurrence frequency of red tide events in the sea areas increased greatly, and the algal toxic infection events of mussel were frequently found in the sea areas.

结果表明，长江向长江口海域输送总氮和总磷通量持续增大，长江口及其邻近海域无机氮浓度持续增高而硅浓度持续下降，并由此导致N/P/Si与比值的显著变化；该海域叶绿素a浓度持续增大，浮游植物群落结构也发生了显著变化；该海域底栖生物种类和生物量都大大减少，底层水低氧区面积也显著扩大；该海域赤潮事件无论是规模还是频率都大大增加，藻类毒素DSP/PSP贻贝传染事件也时有发生。

The quantity and diversity of culturable cellulose-decomposing fungi in these soils are significantly correlated with organic matter, total nitrogen and water content. In addition, the quantity of them are significantly correlated with temperature and altitude. Different plant community and human disturbance have effected on the quantities and diversity of CCDF.

结果发现中低海拔地区土壤CDF数量高于高海拔地区，且数量与样地海拔、土壤含水量、温度、有机质和全氮含量呈显著相关（P.05）；CDF在样地内多样性与土壤有机质、全氮、含水量显著相关（P.05）；植被类型和人为干扰对CDF的数量和分布都有一定影响。
