The synthetic process for a new plasticizer used in low temperature, dibutyl nylonic acid ester, was introduced.

介绍了一种新型耐寒增塑剂尼龙酸二正丁酯的合成工艺，用价廉、易得的尼龙酸(由制己二酸母液中获得的C4～C6混合二元酸)及正丁醇为原料，浓硫酸为催化剂，经酯化、脱醇、中和、沉降及减压蒸馏等工序而制得产品。

This study instead proposes an alternative solution namely carrier docking to enhance sludge settleability by physically increasing sludge density with non-recovered elutriated microsand produced by using an elutriating method in our laboratory.

传统上以设置选种槽等方式改善上述问题，本研究则尝试利用自制之小粒径、低成本且不需回收之淘洗细砂，透过载体嵌合以物理方式增加污泥比重，改善其沉降性。

Conventionally the problem is approached by placing biological selectors preceding the ASP. This study instead proposes an alternative solution namely carrier docking to enhance sludge settleability by physically increasing sludge density with non-recovered elutriated microsand produced by using an elutriating method in our laboratory.

Since the Late Pleistocene the coastal plain subsidence came into a quick phase, because the global eustasy superposed, as a result, the hydrothermal situation and relat...

在晚全新世河流造陆过程中，河流的沉积速率超过了海平面的上升速率，陆地才得以形成。在现代海岸带依然持续构造沉降、河流输沙减少、相对海平面上升的背景下，认识不同时间尺度环境变迁机制是极其必要的。

The feed throughput related to the plate distance and the properties of system were analyzed.

通过实验研究了斜板沉降器板间距对处理负荷的影响。

Chitosan coagulates fine flocci together into lager, impact floccules and greatly strengthens the polymerization degree and coacervation force. The sedimentation rate and adsorption efficiency rise greatly. So the flocculation efficiency of this composite flocculant is superior to the single one.

无机絮凝剂CF-PAC、铝交联蒙脱石主要起吸附作用，而壳聚糖和PAM等有机高分子絮凝剂主要起吸附桥连作用，将细小的絮粒凝结在一起形成更大更致密的絮体，并使聚合度和凝聚力大大增强，从而使其沉降速度和吸附效率大大提高，起到优于单一絮凝剂的絮凝效果。

Inorganic flocculant CF-PAC、Al-pillared rectorite act as sorption mostly ; Meanwhile organic flocculant chitosan acts as the adsorption bridge mainly. Chitosan coagulates fine flocci together into lager、impact floccules and greatly strengthens the polymerization degree and coacervation force. The sedimentation rate and adsorption efficiency rise greatly. So the flocculation efficiency of this composite flocculant is superior to the single one.
