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。

The experiment optimized the culture medium and conditions for PV 1 to yield the highest GABA: sucrose as carbon source,peptone and beef extract as complex nitrogen source,initial pH at 7.0,temperature at 30~34 ℃.The content of GABA was over 4 g/L in the optimum culture conditions.Thereby,i...

实验还对酸菜1号菌株的培养基和培养条件进行了优化：用蔗糖为碳源、蛋白胨和牛肉膏作为复合氮源、培养基初始pH为6.0、培养温度为30~34℃时该菌株发酵产GABA的量最多，发酵过程中的振荡培养(100 r/min)和静置培养对GABA的产量无明显影响；在最佳培养基组合和发酵条件下，发酵液中GABA含量可达4 g/L以上，表明利用乳酸菌进行富含GABA食品的生产是可行的。

Adopting sulphur-free method to protect color, low temperature chowchow, vacuum filter, air current continuous drying and nitrogen-filling packing makes the vitamin and the micro element of the saint female fruit the maximum content.

Make use of HPLC, can availably classify true or false D-calcium pantothenate, the D-calcium pantothenate sample diagram and standard diagram have similar diagram in same reservation time, the content meets provision;The false D is mainly depend on adding calcium inorganic salt, urea and glucose etc, to make specific optical rotation, calcium content, nitrogen content to attain a nation standard, but these material in the same reserve time have never absorbed diagram to make peak area very small, the content of external standard be low.

本文以市售D-泛酸钙为样品(山东新发药业有限公司生产)，对所建立的检测方法进行了验证，通过精密度、准确度和标准曲线等验证项目的实验，结果表明，本文所建立的D-泛酸钙的高效液相色谱检测方法可以准确地检测产品的含量；利用液相色谱图谱，可以有效地区分真假D-泛酸钙，D-泛酸钙样品图谱与标准品图谱在相同的保留时间处，有类似谱图，含量符合规定；搀假的泛酸钙主要靠添加无机钙盐、尿素和葡萄糖等使比旋度、钙含量、氮含量达到国家标准，但这些物质在此处无谱图造成峰面积很小，外标含量低。

Experiment 2: To choose the appropriate dosage of tannins for the diets in sheep, three High Mountain Fine-wool wethers fitted with permanent rumen fistula were used and the 3 ×3 Latin square design were adopted to study the effects of tannins in Sainfoin on protein protection of the diets, measured items included the rumen metabolic parameters, the appatent digestion of all nutrients and the appatent retention of N in sheep.
