包装废弃物问题的治理,根本在于明晰包装产业链及生命周期与包装废弃物产生的关系,构建闭环的包装废弃物回收体系与回收模式。为此,在揭示包装废弃物形成和产生的要素与环节的基础上,试图阐明减少包装废弃物产生与便利回收处理之间的逻辑关系。提出包装废弃物治理必须秉承材料撷取是基础,包装设计是关键,制品生产工艺优化是重点,回收体系与模式是保障的思路和原则,绿色低碳是目标。在大力研发和推广应用新型绿色包装材料的同时,应建立严格的包装制品设计规范和审批制度,淘汰工艺技术落后产能,着力打造由政府主导、政策支持、区域协同、效益驱动、自主与约束相结合的回收体系与模式,建立从回收到分类再到加工处理的完整产业链,从而对包装废弃物实现标本兼治。

The Xitieshan lead-zinc deposit is located at the northern margin of the Qaidam Basin, Qinghai Province, China, and had developed a complete marine sedimentary-exhalative system. Our preliminary study of ore-forming fluids shows that fluid inclusions in quartz from altered stockwork rocks that represent the pipe facies have a wide range of temperature and salinity. The intense fluid activities are characteristics of the pipe facies of the exhalative system. Fluid inclusions in carbonates near the unstratified ore bodies hosted in the thick-bedded marble which represents vent-proximal facies are large in size and have moderate to high temperatures. They represent unerupted sub-seafloor fluid activity. Fluids in altered stockwork rocks and carbonates have similar H20-NaCI-CO2 system, both belonging to the sedimentary-exhalative system. The fluids migrate from the pipe facies to the unstratified ore bodies. Boiling of the fluids causes the separation of CO2 vapor and liquid H2O. When the fluids migrate into the unconsolidated thick-bedded marble, the escape of CO2, decreasing temperature and pressure as well as some involvement of seawater into the fluids result in the unmixing of fluids with high and low salinity and deposition of ore-forming materials. The two unmixed fluids were trapped in unconsolidated carbonates and the ore-forming materials were deposited in the unconsolidated carbonates to form the sedimentary-exhalative type unstratified ore bodies. The oreforming temperature of unstratified ore bodies is up to high temperature indicating that there is a huge ore-forming potential in its deep.

In this study, a novel model of photothermal conversion in a direct absorption solar collector based on the Monte Carlo and finite volume methods was built and validated and the temperatures of the novel and traditional solar collectors were compared. The sensitivity of the parameters to the radiative heat loss was investigated. Finally, the radiative heat transfer characteristics were discussed using the radiative exchange factor. The results of this study validated the advantages of the novel solar collector at both the surface and fluid temperatures. Under the conditions used in this study, the maximum temperature difference of the novel solar collector was 30 K, compared with 193 K for the traditional solar collector. Furthermore, the collector was divided into several units along the flow direction. The radiative exchange factor indicated that with an increase in the attenuation coefficient, the percentage of radiation intensity in the total solar radiation absorbed by the corresponding unit ***, it decreased with an increase in the incident angle and scattering albedo. These results provide a reference for addressing the low efficiency and thermal damage caused by traditional solar collectors at high temperatures.

The autosome dominant disorders, ring dermoid of the cornea (RDC), iris hypolasia (IH) and Axenfeld-Rieger syndrome (ARS), are allelic disor- ders, as all three can result from mutations of the transcriptional factor PITX2. Among three disorder phenotypes, ARS is the most severe, IH is milder than ARS, and RDC is the mildest. Missense muta- tions of the PITX2 homeodomain identified in RDC (R62H), IH (R84W) and ARS patients (T68P) were introduced into PITX2 cDNA by site-directed mutagenesis. PITX2 mutant proteins expressed in eucaryotic cells were stable and localized to the nu- cleus. Analysis of these mutant PITX2 proteins by DNA-binding shift and transactivation studies dem- onstrated that the R62H had the most activity in both studies, and the R84W still retained somewhat func- tions, whereas the T68P proved to be non-functional. These results are consistent with previous hypothesis that varying amount of residual PITX2 mutant activity could underline the severity of these phenotypes.
