查询词典 reduced

The change of remaining litter weight was the largest in the earlier 30 days during 60-day litter decomposition, and there was no significant difference in subsequent 30 days. The phenolic acid content of litter was significantly reduced with the decomposition time prolonging, and the releasing quantity of phenolic acid was the highest at the tenth day. The amounts of soil Aerobic azotobacter, Ammonifier and Aerobic cellulose-decomposer and the soil chemical properties such as pH, phenolic acid content, NH+4-N and available phosphorus were significantly affected by the litter aqueous extract of four decomposition stages.

凋落物分解的60d中，凋落物残留量在前30d内变化最大，30d后无显著变化；凋落物中酚酸含量随分解时间的延长，呈显著降低的趋势，且在分解10d时，酚酸释放量最大。4个分解动态的凋落物浸提液显著地改变了土壤好气性自生固氮菌、氨化细菌、好气性纤维素分解菌的数量和土壤pH值、酚酸含量、铵态氮、有效磷等化学性质。

Increasing the calcining temperature at 1500℃ 5h, the morphologies of the product became the big and wide vermiform-fiber form particles, the length was about 2.5 μm, and the width was about 700 nm. In addition, the vermiform-fiber form particle could be found in the filtrated precipitate with the additional ammonium sulfate. If the ratio of ammonium sulfate to alum is above 1, the vermiform-fiber form particle was formed. After calcined at 1500℃ 5h, the particle grow up to 2μm. Adding ammonium sulfate was also reduced the particles size of alumina because the surface area of the products was increased by increasing the quantity of ammonium sulfate.

在明矾与氨水沉淀物经过滤后再额外添加不同硫酸铵的比例，1200℃ 1hr煅烧后，发现添加硫酸铵比例在1以上，其型态亦为蠕虫状纤维，当以1500℃ 5hr煅烧，蠕虫状纤维型态粒子亦变为又大又胖，其粒子尺寸长度约为 2 μm 宽度约为 500 nm；且将煅烧1200℃ 1hr测其比表面积值，会随著硫酸铵的添加量增加，粉体的表面积会增加且粉体变细，添加硫酸铵比例为 4 者所得粉体粒径最小，从比表面积所得结果估计约 150 nm 。

Lubei Chemical (600727, the closing price of 4.89 yuan) of the Securities Department staff said that the company produces ammonium phosphate, sulfuric acid, cement and other products, as the national economic slowdown, the company has reduced The ex-factory price of the product, but the company has not lowered prices of raw materials, the company's profits by a certain amount of pressure.

A novel synthetic approach of 3,3'-azobis(6-amino-1,2,4,5-tetrazine) was firstly devised. Taking 3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine as a primary material, DAAT was synthesized by high pressure ammonolysis and potassium permanganate oxidation. Compared with the four-step reaction in the literature, this new approach was reduced to two steps with a yield of 58.1%. The intermediate and DAAT were characterized by elemental analysis, IR and NMR spectra.
