为量化评估饰面人造板材生产过程中所产生的环境影响,探索产品的低碳优化方向,本文运用生命周期评价法,聚焦产品碳足迹这一环境属性,对饰面人造板材产品生命周期过程的碳足迹进行了量化分析。以某公司产品的碳足迹评价过程为例,以0.5 mm重组装饰单板为评价对象,进行实地数据收集与计算。结果表明:该重组装饰单板1 m^(2)的产品碳足迹总和值为2.79 kg CO_(2)eq,其高碳排放单元过程为生产制造阶段,碳足迹为1.13 kg CO_(2)eq。热蒸汽能源的使用对碳排放贡献的影响最大,主要发生于染色漂白和单板干燥工序。因此,针对染色漂白和单板干燥工序进行低碳优化,对于降低产品碳足迹具有重要的意义。

Objective： To observe the effect of acupuncture at Jǐngjiājǐ（颈夹脊）on the repair and regeneration of cochlear hair cells of guinea pigs with sensorineural ***： Sixty healthy guinea pigs were selected, 20 guinea pigs were randomly assigned to the normal control group（group A）, and other guinea pigs were randomly divided into model control group（group B） and acupuncture treatment group（group C） after injection with gentamicin sulfate in order to induce deafness. No intervention was given to the guinea pigs in group A and group B, and acupuncture at Jǐngjiājǐ was given to the guinea pigs in group C for 30 days. ABR threshold, DPOAE amplitudes and hair cells counting of guinea pigs in each group were recorded after intervention for 30 ***： After intervention for 30 days, ABR threshold in group C was significantly lower than that in group B（38.46 ±7.36 vs 82.94 ±6.47, P〈0.01）. and the DPOAE amplitudes in group C were obviously higher than that in group B（28.06 ±5.64 vs 25.23 ±5.38, P〈0.01）. The number of cochlear hair cells in group C increased significantly, over 50% of the hair cells survived, accounting for 66.67% of the observation cases. The number of cochlear hair cells in the 3 rd and 4 th gyri was close to the normal level, and plenty of proliferous sustentacular cells can be seen. Compared with group B, the number of cochlear outer hair cells in each gyrus in group C significantly increased（36.76 ±1.97 vs 28.59±2.24, P〈0.01）, indicating that acupuncture at Jǐngjiajǐ can promote the repair and regeneration of cochlear hair ***： Acupuncture at Jǐngjiajǐ can promote the repair and regeneration of cochlear hair cells, thus improving the hearing of guinea pigs with deafness.

In a smart system, the faults of edge devices directly impact the system’s overall fault. Further, complexity arises when different edge devices provide varying fault data. To study the Smart System Fault Evolution Process (SSFEP) under different fault data conditions, an intelligent method for determining the Smart System Fault Probability (SSFP) is proposed. The data types provided by edge devices include the following: (1) only known edge device fault probability;(2) known Edge Device Fault Probability Distribution (EDFPD);(3) known edge device fault number and EDFPD;(4) known factor state of the edge device fault and EDFPD. Moreover, decision methods are proposed for each data case. Transfer Probability (TP) is divided into Continuity Transfer Probability (CTP) and Filterability Transfer Probability (FTP). CTP asserts that a Cause Event (CE) must lead to a Result Event (RE), while FTP requires CF probability to exceed a threshold before RF occurs. These probabilities are used to calculate SSFP. This paper introduces a decision method using the information diffusion principle for low-data SSFP determination, along with an improved method. The method is based on space fault network theory, abstracting SSFEP into a System Fault Evolution Process (SFEP) for research purposes.

In order to improve the multi-ion cooperative transition, we proposed and exploited a novel nanoscale effect, namely the nanoshell effect in bulk materials. Based on the effect, an optimal material structure was designed by coating the surfaces of Ca F_(2):Yb^(3+)micron size particles with ZrO_(2). An about 2 times higher intensity of cooperative luminescence is observed upon laser excitation at 980 nm. Dynamical analysis exhibits that the novel effect plays a key role in improving the performance of cooperative transitions. Our results also suggest that the nanoshell effect in bulk materials is likely to be significant in some special cases, which have not been reported yet in the literature.
