探讨磷硒配施对冬小麦产量及根际土壤微生物群落结构与多样性的影响,明确土壤微生物群落与磷硒有效性的关系。采用盆栽试验,设置3个磷水平(0、0.2和0.4 g·kg^(-1))和2个硒水平(0和0.5 mg·kg^(-1)),完全交互设计,共6个处理(Se_(0)P_(0)、Se_(0)P_(0.2)、Se_(0)P_(0.4)、Se_(0.5)P_(0)、Se_(0.5)P_(0.2)、Se_(0.5)P_(0.4)),分析冬小麦籽粒产量、磷硒浓度、土壤有效磷含量、硒形态转化及微生物群落结构等的变化。施磷显著增加Se_(0)和Se_(0.5)水平下冬小麦籽粒产量、各器官磷浓度及累积量,但显著降低Se_(0.5)水平下根系、茎叶及籽粒硒浓度,且籽粒、颖壳及茎叶硒累积量随施磷量的增加呈先增加后降低的趋势,均在Se_(0.5)P_(0.2)处理下达到最大值。施硒显著增加了冬小麦各部位硒浓度和累积量,降低了P_(0.4)水平下籽粒产量和P_(0.2)和P_(0.4)水平下冬小麦各器官磷浓度及累积量,但对P_(0.2)水平下籽粒产量无显著影响。施磷显著增加了Se_(0.5)水平下土壤有效磷含量、可溶态硒含量及所占比例,施硒显著增加了P_(0.4)水平下土壤有效磷含量。在Se_(0.5)水平下,P_(0.2)和P_(0.4)处理分别显著增加了放线菌门(Actinobacteria)和芽单胞菌门(Gemmatimonadetes)的相对丰度,但均显著降低了拟杆菌门(Bacteroidetes)的相对丰度。施硒显著增加了P_(0.2)水平下放线菌门的相对丰度和P_(0.4)水平下酸杆菌门(Acidobacteria)的相对丰度。在Se_(0.5)水平下,与P0相比,P_(0.2)显著提高了Shannon指数;在P_(0.2)水平下,施硒显著提高Simpson指数。适宜的磷硒配施改变土壤微生物群落结构、促进土壤中磷硒的释放并提高其有效态含量,进而增强磷对冬小麦籽粒产量的促进作用和籽粒硒的累积,以Se_(0.5)P_(0.2)处理为宜。

针对鲸鱼优化算法(Whale Optimization Algorithm,WOA)存在的收敛速度慢、精度低的问题,提出了基于Tent混沌精英和Lévy飞行策略的鲸鱼优化算法(TELWOA)。使用Tent混沌映射初始化鲸鱼种群,保持种群的多样性,并通过引入精英反向学习策略,对初始种群的精英个体生成反向解,选取适应度高的种群作为下一代鲸鱼种群,加快算法收敛速度。其次,通过使用非线性收敛因子,缓解算法全局搜索和局部搜索能力不平衡的现象。最后,在鲸鱼位置寻优过程中使用Lévy飞行策略,避免算法陷入局部最优,提升算法的全局搜索能力。通过对不同改进策略的有效性分析、与其他智能算法的对比分析,证明了TELWOA算法在收敛精度、算法稳定性和全局寻优能力上与对比算法有显著提升,具有一定的实际工程应用能力。

本实验将小儿百部止咳糖浆进行拆方,将生、蜜炙百部分别与陈皮组成药对,采用HPLC法测定其中橙皮苷的含量。结果发现蜜炙百部-陈皮药对中橙皮苷含量(22.77 mg·g^(-1))高于生百部药对(20.61 mg·g^(-1))。说明蜜炙百部与陈皮配伍能促进其主要化学成分橙皮苷的溶出,但较蜜炙百部入小儿百部止咳糖浆中橙皮苷含量增加(约50%)少,说明复方中生、炙百部互换后,不是单一的促进某一成分溶出,而是多种成分相互作用增加各成分的溶出度,这为中药复方的合理性提供实验支持。

Zinc oxide(ZnO) thin films were deposited onto different substrates — tin-doped indium oxide(ITO)/glass, ITO/polyethylene naphthalate(PEN), ITO/polyethylene terephthalate(PET) — by the radio-frequency(RF) magnetron sputtering method. The effect of various O2/(Ar+O2) gas flow ratios(0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6) was studied in detail. ZnO layers deposited onto ITO/PEN and ITO/PET substrates exhibited a stronger c-axis preferred orientation along the(0002) direction compared to ZnO deposited onto ITO/glass. The transmittance spectra of ZnO films showed that the maximum transmittances of ZnO films deposited onto ITO/glass, ITO/PEN, and ITO/PET substrates were 89.2%, 65.0%, and 77.8%, respectively. Scanning electron microscopy(SEM) images of the film surfaces indicated that the grain was uniform. The cross-sectional SEM images showed that the ZnO films were columnar structures whose c-axis was perpendicular to the film surface. The test results for a fabricated ZnO thin film based energy harvester showed that its output voltage increased with increasing acceleration of external vibration.

Nickel-containing stainless steels have been widely applied in watch and jewelry production, and their re- sponses to the Nickel Directive become a universal concern in the industry. The nickel release rates and corrosion be- haviors of types 316L, 304, 303 and 201 stainless steels under the conditions of solid solution and mirror polishing were studied by artificial sweat soaking and electrochemical methods. The results show that the weekly nickel release rates in artificial sweat do not strictly correspond to the nickel contents, which present a descending order as 303 stainless steel of 2.06 μg/cm2 , 201 stainless steel of 1.51 μg/cm2 , 304 stainless steel of 0.08μg/cm2 and 316L stainless steel of 0.02 μg/cm2. Both the nickel release rates of type 303 and 201 stainless steels significantly exceed the threshold values regulated in EN1811 ： 2011 ; therefore, they should be avoided to be used as watch and jewelry materials owing to the risk of nickel sensitization. The nickel release rates of 316L and 304 stainless steels meet the requirements of the standard. Sulfide inclusions in stainless steel become the sources of pitting and exacerbate the damage of the passivation membrane, which is the significant cause to enhance the nickel release rates.
