Organic matter and available n of topsoil decreased in recreational areas , but the soil bulk density and ph increased . affected by garbage decomposing , soil available p concentration varied obviously in recreational areas 活动区土壤有机质含量降低， ph值升高，容重增大，碱解氮含量降低，受垃圾分解影响，速效磷含量发生变化。
The activity of cells became weaker and weaker with exposure time . it was conspicuous that uva damaged the activity of cells . the contents of mda upgraded and the contents of gsh - px degraded 结果表明：随着uva照射时间的延长，细胞的活性明显降低，说明uva对细胞的氧化损伤是明显的，其中表现为mda的含量升高、 gsh - px的含量降低。
The contents of the a - helical and p - turn conformation in the secondary structure of the mp - 11 molecule increase and the content of the random coil conformation decreases due to the coordination of cd2 + with s in the peptide of mp - 11 firstly 由于cd ~ ( 2 + )优先与多肽链中的s键合，引起mp - 11二级结构有规结构含量增加，无序结构含量降低。
For example , those who have been advised to reduce their total dietary sodium intake could actively look out for products naturally low in salt or sodium ; or products which have been modified to create lower sodium content than standard 例如，那些被建议降低钠摄入量的人就要主动地寻找天然的低盐或低钠食物，或者是经过加工后钠含量降低的食物。
4 . in the process of spontaneous vegetation recovery of blown sand soil , coarse sands ( l - 0 . 25mm ) content gradually lower , middle sands ( 0 . 25 - 0 . 05mm ) and fine sands ( 0 . 05 - 0 . 02mm ) , silt , clay content gradually higher in mechanical composition 4 、在自然植被恢复过程中，风沙土机械组成中砂粒含量变化表现为粗砂含量的降低，中砂和细砂含量的升高，砂粒整体含量降低。
Conclusion . an in vivo model simulating physiologic levels of glycosaminoglycan loss was created to aid in understanding the relationships between altered biochemistry , altered mechanics , and altered cellular function in degeneration 结论：我们创造一种氨基葡聚糖含量降低到生理水平的体内模型，目的是为了了解椎间盘生化改变、力学改变和退变椎间盘细胞功能改变之间的相互关系。
1 . it imply abundant meal fiber in the burdock root root , the meal fiber has the function of adsorb the , and can eject the body with the excrement , making the content of the inside the body lower , thus attaining the purpose of decline the blood pressure 1 .牛蒡根中含有丰富的膳食纤维，膳食纤维具有吸附钠的作用，并且能随粪便排出体外，使体内钠的含量降低，从而达到降血压的目的。
4 ) soil nutrient of leguminosae also higher than non - vegetation soil ; while organic matter and available k increased , there was no significant change in total n ( it increased slightly ) ; available p and soil ph decreased 4 )豆科植物较无植被覆盖地，土壤养分朝着良性循环转变。土壤有机质、速效钾含量提高，全氮含量稍有增加，速效磷含量降低， ph值有所下降；这些变化主要发生在土壤表层。
In the same time , it would increase in the contents of the a - helical and p - turn conformation in the secondary structure of the mp - 11 molecule and decrease in the content of the random coil conformation , leading the increase in the exposure extent of heme group 同时也使mp - 11二级结构中有规结构含量增加，无序结构摘要含量降低，使血红素的暴露程度增加，而使mpll的电化学反应可逆性增强。
The results in these two respects indicated that shading first exerted influence on the development of inner membrance systems in the leaves of a . vera l . and then affect aloin synthesis and transport thereby reducing the aloin content in the leaves of a . vera l 综合两方面的实验结果认为，遮荫首先影响芦荟叶片细胞内膜系统的发育，进而限制了芦荟素的合成和运输，使芦荟叶片中芦荟素含量降低。
