针对冬季低温堆肥启动困难这一技术问题,优化和复配低温复合菌剂,并在有机肥厂冬季堆肥生产中对菌剂的应用效果进行评估。选取分离于极地的菌株,对菌株低温生长特性、产蛋白酶性能进行测定,选择供试菌株边缘假单胞菌MP-1(Pseudomonas marginalis)、硬结节杆菌AS-3(Arthrobacter scleromae)和水稻节杆菌AO-4(Arthrobacter oryzae)进行复配,3个菌株在15℃条件下均可快速生长,菌株MP-1、AS-3和AO-4于15℃条件下培养24 h,蛋白酶活性分别可达82.1、64.3和80.3 U·mL^(-1)。将3个菌株按照体积比2∶1∶1复配复合菌剂(IM)。利用中药渣、鸡粪和茶粕堆肥的原料浸提液进行菌剂生长试验,结果表明,IM菌剂在中药渣堆肥浸提液中24 h生长量为1.04×10^(10)cfu·mL^(-1);在鸡粪堆肥浸提液中生长量为1.41×10^(10)cfu·mL^(-1);在茶粕浸提液中生长量为3.6×10^(6)cfu·mL^(-1)。将IM复合菌剂应用于有机肥厂冬季堆肥生产中,设置市售常规堆肥接种剂为对照,结果表明IM菌剂可有效促进冬季低温环境下鸡粪堆肥快速启动,启动阶段IM处理升温速度为19.4℃·d^(-1),对照组为15.84℃·d^(-1);与对照处理相比,IM提前3 d进入高温期;堆肥35 d时,处理组全磷和全钾含量分别增加2.32和4.27个百分点,IM种子发芽指数(GI)可达到93.3%,比对照组高10.2个百分点。综上所述,接种IM菌剂可有效促进低温堆肥快速启动,缩短堆肥周期,促进有毒物质分解,加快低温堆肥的无害化进程,提高冬季低温堆肥效率。

Since trim and sinkage are significant while vessels are advancing forward with high speed, the predicted vessel resistance based on restrained model theory or experiment may not be real resistance of vessels during voyage. It is necessary to take the influence of hull gesture into account for oredicting the resistance of high-speed ship. In the present work the resistance problem of high speed ship is treated with the viscous flow theory, and the dynamic mesh technique is adopted to coincide with variation of hull gesture of high speed vessel on voyage. The simulation of the models of S60 ship and a trimaran moving in towing tank with high speed are conducted by using the above theory and technique. The corresponding numerical results are in good agreement with the experimental data. It indicates that the resistance prediction for high speed vessels should take hull gesture into consideration and the dynamic mesh method proposed here is effective in calculating the resistance of high speed vessels.

针对行人重识别任务中数据标注困难以及服装变化问题,基于无监督方法PPLR(Part-based Pseudo Label Refinement)提出了一个多粒度特征网络(Multi-grained Feature Network,MGFNet)。仅输入RGB图像,即可充分提取图像中行人的全局、局部和脸部特征,根据注意力机制针对性地抑制特征中的服装信息,挖掘行人的本质特征。融合全局、脸部和局部特征,根据聚类算法生成精确的伪标签监督模型训练。在公开的换装数据集上测试MGFNet性能,并设计消融实验验证MGFNet的有效性。实验结果表明,MGFNet的mAP和Rank-1指标在PRCC数据集上分别比基准模型PPLR提高了6.9%和15.8%。

Multiwall carbon nanotube-supported Pt （Pt/MWNTs） catalysts with high dispersion and high loading of Pt were prepared by chemical reduction method and the loading of Pt got to 40 wt%. The average diameter of Pt nanoparticles on MWNTs was about 3.5 nm. When the hydrogen and air were used as reactant gases for PEMFC, Pt/MWNTs catalysts showed significantly higher performance than the Pt/XC-72 （carbon black） catalysts.
