In addition, the pCO2 in the hypolimnion near the sediment is the highest and has an increasing tendency, which indicates that the degradation of organic matter in the sediments has an important effect on the pCO2 in the hypolimnion.

静水层沉积物附近pCO2最高并且还有持续增加的趋势，说明沉积物中有机质降解是静水层中CO2增加的主要原因，夏季湖底水温较高加快了沉积物中有机质的降解。

The α-helical structure of the globulin is an important factor to forming and stabilizing the protein emulsion. The particle size distribution of legumin and vicilin hydrolysates were measured by dynamic light scattering, the particle size of legumin hydrolysates was decreased at first then increased during the papain hydrolysis, but the vicilin hydrolysates decreased continuously, it demonstrated that the legumin hydrolysates might have a re-aggregation in the solution which the vicilin hydrolysates did not have.

采用动态激光光散射分析了水解产物的粒径分布，结果表明：随着水解的进行，11S球蛋白水解物在溶液中的粒径出现先减小后增加的趋势，而7S球蛋白水解物的粒径呈递减趋势，说明11S水解产物分子间发生了新的选择性定向和聚合，而7S水解物分子间未发生二次聚合。

Results The invalid areas surveyed by bait method accounted for 53%, suggesting that the inducement of sweet potato was very weak. Successful surveillance area accounted for 8% and 67% by trap method and powder-trace method, respectively, showing that the reason leading to the insensitivity of rodent to trap method was its strong repellence to new substance.

结果 食饵法监测失败的区域占53%，说明红薯的引诱力不强致使敏感度较低；鼠夹法、粉迹法成功监测的区域分别为8%和67%，说明鼠夹法敏感度较低的主要原因是鼠对鼠夹有较强的新物反应。

Three kinds of CpTiCl had been synthesized when was catechol , 2, 2′-biphenol , or 2, 2′-binaphthol , respectively. In the case of CpTiCl〓, was 8-hydroxylquinoline , 2-methyl-8-hydroxyl-quinoline , and 8hydroxyl-5-nitro-quinoline , respectively.

研究表明，这三类半茂钛配合物在助催化剂MAO作用下，于30℃、0.1MPa乙烯压力下均可催化乙烯聚合，并显示较高的活性，远高于未引入非茂配体的CpTiCl〓及不含茂环的相应非茂配合物的活性，这说明同时含一个茂配体和一个非茂配体的半茂配合物是烯烃聚合的优良催化剂。

A cDNA segment was isolated from M. meretrix larvae. The results of caspase in situ detection in larval developmental stages revealed that there were activated caspase from L1 to L3, indicating caspase is involved in the whole developmental process. The main apoptosis area was found in velum at L3 before metamorphosis, indicating the degradation of velum might be the process of apoptosis. The larvae before metamorphosis were treated by caspase specific inhibitor to analyze the role of caspase in this process. The results indicated that caspase have function metamorphosis.

根据caspase在不同物种中的保守区域设计简并引物，在文蛤幼虫中扩增到cDNA序列片段；检测有活性的caspase在文蛤幼虫各发育时期的分布部位，发现其在L1至L3期幼虫中都有分布，说明整个幼虫形态变化过程中都有caspase的参与；细胞凋亡检测结果显示，幼虫主要发生细胞凋亡的部位在L3期幼虫的面盘，即变态过程中要退化的器官，说明细胞凋亡可能是文蛤幼虫变态过程中面盘退化的主要机制；用caspase特异性抑制剂处理变态前幼虫，发现幼虫变态率下降，初步验证了caspase在文蛤幼虫变态过程中的作用。

Bio-Ba/Ti, bio-Ba /Al were chosen as the sensitive markers to show the variation of the biogenic/terrigenous suspended particles in MNLS through the correlation analysis of 12 major elements of the suspended particles. Comparing with the overlain waters, the content of terrigenous particles in the BNL was increased significantly, but was lower than that in the surface sediment.

与上覆水体相比，近底雾状层内陆源组分显著增加，但较底质沉积物为低；生源组分则明显降低，但比底质沉积物为高，这一规律说明底质沉积物再悬浮对近底雾状层有显著的影响，表明Ba_/Ti和Ba_/Al值可以作为近底雾状层颗粒物的高精度示踪指标，其中Ba_/Al值尤为敏感。

The carboxyl of the tripodal ligand is a goodbridging group. The building blocks are linked together by the bridging group andother weak interactions (hydrogen bond and π-π stacking interaction, etc), thusgenerating a one, two or three-dimensional metal complexes.2. Studies on the fluorescence properties of the lanthanide complexes indicated that:(1) The excitations in the ligand-based π-π〓 transitions cause the structuredemission of lanthanide complexes while the ligand luminescence is completelyquenched showing that ligand-to-metal energy transfer occurs.

三脚架配体所带的羧基是一个很好的桥联基团，配合物的结构基元通过这种基团的桥联作用及其它一些弱的作用力(如氢键、π-π堆积作用等)联系起来，构成了一维、二维或三维的超分子空间结构。2、稀土配合物的发光研究发现：(1)用配体的π-π〓跃迁波长进行激发，配合物均显示出稀土离子的特征发射峰，同时，配体的荧光峰没有出现，这说明在三脚架配体与稀土离子间进行了有效的能量传递。

The phosphorus forms and BAP vary with horizontal and vertical positions. The total phosphorus, inorganic phosphorus, BAY, and iron-phosphorus contents were high at a depth of 0~20 cm at the first sampling point, and then decreased at 20-40 cm of depth. This shows that the potential release capacity of P at 0-20 cm of depth is higher. The concentrations of total phosphorus and inorganic phosphorus decreased at 0~20 cm of depth and increased at 20~40 cm of depth at the second sampling point, but BAY and Fe-P increased along with the depth consistently. This shows that the deeper layer at the second sampling point had a higher potential release capacity of phosphorus.

不同地点沉积物各磷形态和BAP的垂向变化有较大的差异。1号采样点的总磷、无机磷、铁磷和BAP质量比在沉积0~20 cm处较高，20~40 cm逐渐减小，说明0~20 cm内释磷潜力较大；2号采样点的总磷和无机磷质量比先减小，20~40 cm逐渐增加，而BAP和铁磷质量比随深度增加呈上升趋势，说明2点深层具有较大的释磷潜力。

Percents of N immobilization were positively correlated with the litter mass loss, indicating forest floor with easily decomposition litters may have greater potential of N sinks than that with hardly decomposition litters.

在本实验中易分解凋落物具有较高的氮固持百分比，可能说明具有较易分解凋落物的森林表层可能比具有较难分解的凋落物的森林表层具有较大的氮固持潜力。

In the dissertation, a new stabilization method, equal-density method was adopted to prepare modified asphalts with storage stability at high temperature. In this method, a compound was prepared by premixing polymer and filler, and the compound was mixed with asphalt to prepare Polymer-Modified Asphalt by changing the ratio of polymer and filler. The asphalts with good storage stability were formed with the addition of filler, by regulating the density difference between polymer and asphalt. With identifying the effect of composition factor and the technique conditions on mechanical properties of polymer/filler compound and the molecular distribution of the polymer, identifying the effect of composition factor and the technique conditions on the properties and structure of polymer/filler modified asphalt, Styrene-Butadiene-Styrene copolymer, Low Density PolyEthylene, Styrene-Ethylene-Butadiene-Styrene block copolymer modified asphalts with good storage stability and performance were prepared. Rheological method, gel content analysis and swelling measurement were adopted to elucidate the interaction between the polymer and filler. Filler reduced the difference between the polymer and asphalt with the premixing technique, which led to the improvement of the storage stability of the modified asphalts. The thermo-oxidative aging process of base asphalt and PMA were studied and the effect of antioxidant additives on the base asphalt and PMA were analyzed.
