酸雨

The preliminary results showed that the atmosphere contaminator mainly contained SO\-2, NO\-\%x\% and suspended granule. Which caused large area acid rain with high frequency. As pollution became more serious, there were decreases in pH value and increases in the content of SO\+\{2-\}\-4 and Al\+\{3+\} in forest soil; the chlorophyll concentration also would decrease...

初步结果表明：大气污染引起珠江三角洲地区发生大面积、高频率的酸雨，主要的污染物有SO2 、NOx、悬浮颗粒物等；随着污染程度的增大，森林土壤pH值降低，SO2 - 4和Al3+质量浓度增大；马尾松、湿地松叶片叶绿素含量降低，生长衰退甚至死亡；但不同树种对大气污染敏感程度不同，种植马占相思比马尾松更能增加林地对酸雨缓冲力和提高土壤肥力。

During the course of acid rain eluviation, Zn shows the most activation.

酸雨淋滤过程中重金属元素的活动特性一方面可能取决于土壤整体缓冲酸雨的能力，另一方面更主要的可能与其在土壤中的存在形式有关。

During the course of acid rain eluviation, Zn shows the most activation. Although Zn does not seem to be obviously anomaly, it has the highest concentration in soil solution and eluviation solution, the most activation heavy metal element in acid rain effect. Other elements including Hg, As, Cd, Cu, Pb etc.

已有大量研究结果表明，冲积平原区土壤中的Hg异常主要与Org.C有关，本次试验中又在土壤天然重砂中发现了辰砂矿物，Hg的上述存在形式特征决定了它在酸雨淋滤过程中的活动特性。3、酸雨作用下离子的迁移过程客观存在，这一点从土壤电导率研究结果中得到了确认。

The flexible-wall permeameter was adopted to simulate the acid rain and action of microorganism which influences the long-term permeability of solidification sludge, moreover, the mechanism of permeability change was analyzed.

3采用柔性壁渗透仪模拟酸雨以及微生物强化条件，开展了酸雨和微生物的活动对固化污泥的长期渗透性的影响研究，并对渗透性变化的机理进行了分析。

The acid rain cause the cytoplasm, MDA content and praline content increase, the lower the pH values of simulated acid.

酸雨引起板蓝根种子的细胞质膜透性、丙二醛和脯氨酸含量上升，模拟酸雨的pH越小，这种生理反应就越明显。

Has weak activation and transfer under acid rain effect and redeposition will take place during the course of their moving from surface soil to deep soil. Contrasted quality standard analysis of surface water, ground water and drinking water, these elements will not bring about negative effect to the water environment and ecological environment of soil.

进一步相态分析结果表明，受酸雨淋滤作用的影响，离子的迁移主要发生在盐基离子上，具体表现在经酸雨淋滤后表层土壤水溶态组分中盐基离子浓度降低，与此相对应的是Al离子浓度显著增高，一个直观的反映是土壤的电导率降低。

The influence of acid rain soaking on thermostability and water vapor permeability of the leather s were investigated.

采用不同的加脂剂对猪蓝湿革进行加脂处理，并将所得到的加脂皮革在人工配制的酸雨中浸泡一定时间，考察了酸雨浸泡处理对加脂皮革透水气性能和耐干热收缩性能的影响。

Thymol is recommended as biocide to prevent microbial uptake and conver sion of organic acids if refrigeration cannot be used as sample preservation in the technical manual for monitoring wet deposition.

在东亚酸雨监测网湿沉降监测的技术指南中，百里酚作为杀菌剂被推荐用于预先加入采样容器以抑制微生物对有机酸的分解，解决没有冰箱或难以使用冰箱地区的酸雨样品保存问题。

The result showed that the activity of photoreduction,photophosphorylation and SOD in chloroplasts increased when reactionmedium added calcium with concentration of 0.04mmol/L,lessened theaccumination of free radical and the destruction of membrane system,which manifested the indirectly antiacid function.

酸雨胁迫降低龙眼的坐果率，并且坐果率随酸雨pH的下降而下降，同时使单果重、TSS、固酸比和糖酸比下降。pH3.5处理的K+、Ca2+、Mg2+和可溶性糖的渗出量与对照差异达极显著水平，说明已对果实品质造成影响。

The field acid rain spray system was adopted to study the effects of simulant acid rain on leaf injury and chlorophyll content, photosynthesis, permeability of cell membrane, stomatic impedance, and transpiration intensity of 11 crops.

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
