本文采用人工神经网络(ANN)与进化算法(特别是阿基米德优化算法(AOA)和水循环算法(WCA)相结合的方法)对非线性磁流体动力学(MHD)的Jeffery-Hamel问题,特别是收敛和发散通道中的拉伸/收缩问题进行了数值研究。这种组合技术被称为ANN-AOA-WCA。将基于复杂非线性磁流体动力学Jeffery-Hamel问题的偏微分方程转化为速度和温度的非线性常微分方程系统,我们建立了基于人工神经网络的适应度函数来求解非线性微分问题。随后,采用了一种新的AOA和WCA结合方法(AOAWCA)来优化基于神经网络的适应度函数,并确定了神经网络的最优权值和偏差。为了证明提出混合方法的有效性和多功能性,探索了一系列雷诺数、通道角和可拉伸边界值的MHD模型,从而开发了两种不同的情况。ANN-AOA-WCA的数值结果与参考解(NDSOLVE)非常接近,NDSOLVE与ANNAOA-WCA的绝对误差约为3.35×10^(−8),对可拉伸收敛和发散通道的理解特别关键。此外,为了验证ANN-AOA-WCA技术,我们对150多个独立运行进行了统计分析,以获得适应度值。

Nitrogen (N) plays a vital role in the productivity of maize (Zea mays L). To investigate the fertilizer effects of N on the yield and growth of maize hybrid variety (Gorilla), the experiment was carried out at the research farm of University of Swabi, Pakistan, during summer 2017-18. Four levels of N (Urea, Urea + Farm Yard Manure (FYM), Urea + Compost, Urea + Poultry Manure (PM)) were set in the present study. Randomized complete block design (RCBD) was used with split-plot arrangement with N administering to main plot. Results showed that yield and other traits, i.e. plant height, ear length, ear weight, kernel yield, kernels ear-1 and harvest index (HI) were significantly affected by Nitrogen. In current study, the maximum performances of plant height (231.46 cm), ear length (12.17 cm), kernels ear-1 (434.83), kernel yield (2095.7 kg·ha-1), total kernel weight (350.75 kg·ha-1), biomass yield (4015.3 kg·ha-1) and HI (37.31) were recorded under the treatment of UREA + PM, and followed by UREA + FYM. Besides, the applications of organic manure in combination with nitrogen significantly increased yield and its components. Application of 50% of N and 50% of poultry manure produced higher performance for the traits of plant height, ear length, kernels ear-1, total kernels weight ear-1, kernel yield, and biomass yield.

为探索河西灌区青贮玉米高产高效的栽培措施,设置67 500株/hm2(L)、82 500株/hm2(M)和97 500株/hm2(H)3个种植密度及不施氮(N0)、施氮120 kg/hm2(N1)、240 kg/hm2(N2)和360 kg/hm2(N3)4个施氮水平.结果表明:在玉米6叶期和12叶期各施氮处理的株高、茎粗、相对叶绿素含量(SPAD)、叶面积指数(LAI)和地上干物质量(ADM)无显著差异,但在灌浆期和收获期M、H密度下,N2和N3的上述指标显著高于N0,且N1、N2和N3的鲜干草产量显著高于N0.在收获期L的SPAD和茎粗显著高于H,而LAI、ADM和鲜干草产量显著低于M和H.N2和N3较N0显著提高粗蛋白、粗脂肪和粗灰分含量,显著降低淀粉和酸性洗涤纤维(ADF)含量,从而提高相对饲用价值(RFV),且N2和N3的各营养成分产量显著高于N0.随种植密度的增加,粗蛋白、淀粉和粗脂肪含量降低,而中性洗涤纤维(NDF)和ADF增高,致使RFV下降,但M和H的粗蛋白、淀粉和粗灰分的产量显著高于L.N1、N2和N3的水分利用效率(WUE)显著高于N0,M和H的WUE显著高于L,所有处理中MN2的WUE最高.因此,82 500株/hm2的种植密度结合240 kg/hma的施氮量是一种适宜河西灌区青贮玉米生产的栽培措施.

The present research work was carried out to investigate the proximate composition and antioxidant capacities of newly invented varieties of dry peas. The proximate composition in terms of moisture （7.00-8.50%）, ash （3.85-4.97%）, fiber （3.8-12.3%） and protein （17.3-18.8%） contents varied significantly with respect to various cultivars. Total phenolic contents （TPC）, total flavonoids contents （TFC）, percentage inhibition of peroxidation of linoleic acid system, reducing power and DPPH free radical scavenging capacity of different dry peas extracts were found in range of 0.651-0.684 g/100g of GAE, 0.021-0.041 g/100g of CE, 0.713-0.895, 40.051-84.608%, 18.097-24.591 mg/mL, respectively. The amount of TFC, and percent inhibition of per oxidation in linoleic system of different dry peas extracts varied significantly among various cultivars and solvents. From the results of present investigations it is reasonable to say that 80% methanolic extracts of dry peas have exhibited varying degree of antioxidant activity.
