为提高图像清晰度，解决传统图像在去雾过程中存在的特征提取困难、去雾不彻底等问题，提出一种基于生成对抗网络的多特征融合端到端去雾网络。该网络由生成器和判别器组成，生成器采用编解码结构，通过多特征提取融合（MFEF）块提取多种感受野下的高维表征信息。判别器使用一系列卷积计算对生成图像和清晰图像进行特征差异分析，引导生成器输出更加真实的去雾图像。实验结果表明，该算法在有效消除雾霾干扰的同时，能够最大限度地保留图像的原始色调。与现有方法相比，该算法在峰值信噪比、结构相似性客观评价指标上分别提升了2.588 dB、2.66%。

A typical mineral processing agent benzo hydroxamic acid(BHA) was degraded by thermally activated potassium persulfate(PS). The effects of temperature, PS concentration, BHA concentration, pH and anions on the degradation effect of BHA were investigated. The degradation mechanism was determined by analyzing the degradation products and the active species of the system, and the toxicity of the degradation system was verified by the germination experiment of mung bean. The results showed that the higher the concentration of PS and the higher the temperature, the better the degradation effect. Under the condition of 70 °C and 1. 5 mmol/L of PS, the removal rate of 20 mg/L BHA reached 91. 34% in 120 min. The degradation of BHA was promoted by both strong acidic and alkaline conditions. HCO孑, SiO$_, and Cu2+ were beneficial to the removal of BHA. SO「 * played an important role in the degradation of BHA during the thermally activated PS system. The main products of BHA were benzoic acid and hydroxylamine, and the adding of Cu2+ promoted the transformation of hydroxylamine to gaseous nitrogen. The mung bean germination test showed that the toxicity of the beneficiation waste water after treatment was significantly lower than that of the original solution. [ABSTRACT FROM AUTHOR]

【Objective】The present study aimed to identify the new loci/genes controlling uppermost-internode length and explore the molecular genetic mechanism of the uppermost-internode length in ‘Pubing3228’. 【Method】The high density molecular linkage map was constructed for the RIL population derived from the cross between ‘Pubing3228’ and ‘Jing4839’using 55K SNP chip. Inclusive Composite Interval Mapping method was used to carry out QTL mapping for uppermost-internode length. Based on the identified QTLs, the candidate genes were predicted for uppermost-internode length.【Result】The large variation was found for the uppermost-internode length in the RIL population and the uppermost-internode length of each line varied from 16.00 to 117.50 cm. Total of 6 QTLs were identified for uppermost-internode length and these QTLs were distributed on chromosome 2B, 4B, 4D, 5B and 6D. LOD value of these QTLs varied from 2.55 to 7.88 and the phenotypic variation explaination（PVE) of that ranged from 3.43% to 15.84%. Furthermore, most QTLs were contributed by ‘Pubing3228’. Two major QTLs were identified for uppermost-internode length. One was QUIL-4B.e1 and was mapped to the distance between AX-109373490 and AX-111540511 on chromosome 4B. Another was QUIL-4D.e1 and was mapped to the distance between AX-110984743 and AX-109230716 on chromosome 4D. One reliable QTL, QUIL-4D, was detected under two environments. The candidate analysis was performed for uppermost-internode length and 15 candidate genes were obtained. These candidate genes mainly encoded some related proteins and functional enzymes, which could regulate or affect plant metabolic activities and thus affect the uppermost-internode length of wheat. For example, TraesCS4D01G039200 possibly encoded a fibrillar family protein that could directly affect the uppermost-internode length of wheat. TraesCS4D01G040300 possibly encoded a metabolite transporter protein, which may affect the length uppermost-internode of wheat by regulating the distribution of metabolites in the uppermost-internode region. 【Conclusion】Total of 6 QTLs and 15 candidate genes were identified for uppermost-internode length. These results not only help to elucidate the genetic mechanism of uppermost-internode length but also provide new wheat germplasm and effective information for the improvement of uppermost-internode length in the future.
