The text studied effects of acid materials on pH value in calcareous soil ; studied effects of phosphoric acid (H2SO4 as control) on pH value and micronutrient availability ; studied relation between P and available Fe, Zn in plant; studied effects of acid material on growth of acidophilic plant.

本文采用室内模拟试验和盆栽试验相结合的方法，研究了不同酸性物质对石灰性土壤的酸化效果；磷酸和硫酸对石灰性土壤pH值及微量元素有效性的影响；植物体内磷、有效铁、锌的关系；不同酸性基质对嗜酸植物生长的影响。

The results demonstrated that the intracellular pH change was different when the Hela cells was treated with different anti-tumor drugs, some would caused intracellular acidification, some would caused ntracellular basification, and some would barely caused pH change. The single living Hela cells uptaken with the ratiometric pH nanosensor was also imaged with laser confocal microscope, which were treated with anti-tumor drugs.

以甲苯二异氰酸酯、聚丙二醇醚(PPG 2 2 0 )和二羟甲基丙酸为原料制备了阴离子型水性PU 乳液，研究了DMPA用量、n /n值、交联剂TMP用量对水性PU 乳液与涂膜性能的影响，得出了制备阴离子型水性PU 的最佳配

Sawdust cellulose xanthate was prepared from sawdust of the wood machining industry,and the processing parameters were optimized.

以木材加工行业所产废弃物木屑为原料研制出木屑黄原酸酯，研究了木屑黄原酸酯的使用量、作用时间、pH值和温度对重金属离子废水处理效果的影响。

This experiment is designed to analyze the effects of different temperatures and pH on lactic acid bacteria isolated from koumiss by improved MC culture. The OD600, pH and vaccine opacity of the culture at terminal were measured.

实验用改良MC培养基为载体，通过目测菌液浑浊度，测定菌液OD600值和培养终点时pH值，对从酸马奶中分离出的乳酸菌的生长温度及pH值进行了研究。

Irmer Mongolian semi-fine wool wethers fitted withpermanent cannules at the rumen proximal duodenum and terminal ileam were used todetermine dietny postruminal starch digestibility in the small intestine by SIF technique.

常用饲料代谢葡萄糖值本章计算出常用饲料中过瘤胃淀粉提供的葡萄糖值与韩飞Q）硕士论文中计算出的常用饲料中瘤胃发酵产生的丙酸转化形成的葡萄糖值合。

Fatty acid compositon is the primary acid component that can react with metal ions in DCS to form sticky insoluble soap; while resin acid does not form soap with metal ions at lower temperature and does form insoluble soap with less sticky at higher temperature. pH value is the key factor influencing the deposit of pitch with the presence of DCS in DIP, there is little deposit at lower pH however the deposit increases obviously with the increase of pH.

脂肪酸是与脱墨浆 DCS 中金属离子形成黏性不溶性皂的主要酸性组分，树脂酸在低温时几乎不形成皂，高温时有不溶性皂产生但沉积性较低。pH值是影响树脂在脱墨浆 DCS 存在时沉积的关键因素，在低 pH值时胶体树脂沉积程度较低，而在中碱性 pH 值时，沉积量显著增加。
