在艺术院校中,以常规方式开展语文教学有诸多不足,因而需要调整教学方法,将语文教学与艺术理论相融合,提高学生的艺术理论修养,提升课堂教学的效率。教师可有意识对比同一题材的不同艺术表现形式,以及不同时期的不同版本来分析文学与其他艺术形式之间的关系,从而启发学生思考,培养学生的思辨能力及艺术思维。同时应注重向古典文学汲取营养,使之具备较为扎实的古文功底,为今后的专业创作、改编提供可能。如此才能真正做到文化与专业相互促进,使学生在艺术之路上获得更长远的发展潜力。

Glycogen storage diseases （GSD） are inherited metabolic disorders of glycogen metabolism. Different hormones, including insulin, glucagon, and cortisol regulate the relationship of glycolysis, gluconeogenesis and glycogen synthesis. The overall GSD incidence is estimated 1 case per 20000-43000 live births. There are over 12 types and they are classified based on the enzyme deficiency and the affected tissue. Disorders of glycogen degradation may affect primarily the liver, the muscle, or both. Type I a involves the liver, kidney and intestine （and I b also leukocytes）, and the clinical manifestations are hepatomegaly, failure to thrive, hypoglycemia, hyperlactatemia, hyperuricemia and hyperlipidemia. Type Ilia involves both the liver and muscle, and lib solely the liver. The liver symptoms generally improve with age. Type IV usually presents in the first year of life, with hepatomegaly and growth retardation. The disease in general is progressive to cirrhosis. Type Ⅵ and Ⅳ are a heterogeneous group of diseases caused by a deficiency of the liver phosphorylase and phosphorylase kinase system. There is no hyperuricemia or hyperlactatemia. Type Ⅺ is characterized by hepatic glycogenosis and renal Fanconi syndrome. Type Ⅱ is a prototype of inborn lysosomal storage diseases and involves many organs but primarily the muscle. Types V and Ⅶ involve only the muscle.

无刷双馈电机由于结构简单、可靠性高、变频器容量小等优点在恒频变速发电领域受到广泛关注,其定转子的槽数配比对电机性能与振动具有一定程度的影响。为探究这一问题,该文以绕线式无刷双馈电机定转子磁势分析为基础,推导不同槽配合的电磁力波对比以及槽配合对电机性能的影响,给出3种符合要求的槽配比方案,计算出各方案转子绕组谐波,并进行对比分析;利用有限元法对48/36槽、42/36槽与36/30槽3种方案在相同要求下的负载性能进行研究,导出定子齿部电磁力,对电机进行振动响应分析对比;最后,通过样机试验,验证有限元仿真的正确性,同时试验结果也证明所选槽配合下电机具有振动形变量小、转子电流小、系统输出电压和效率高、饱和程度低等优点。

针对长短期记忆网络(LSTM)应用于光伏发电功率预测时存在的耗时长或精准度低的问题,提出基于灰狼算法(GWO)优化门控循环单元(GRU)的光伏发电功率预测模型。通过GWO算法优化GRU模型的超参数,以近似最优参数建立光伏发电功率预测模型。结果表明,长时功率预测时,GWO-GRU模型的均方根误差更低、拟合系数更高、耗时更少,比传统LSTM模型的平均绝对误差降低10.20%;短时功率预测时,GWO-GRU模型在3种典型天气条件下不仅预测的平均误差最低、稳定性最强,而且比GWO-LSTM模型的平均用时节省17.24%。不同时长的功率预测表明,GWO-GRU相对于LSTM光伏功率预测效果更佳。

为了提高微电网日常运行的经济性和环保性,以及解决鲸鱼算法(WOA)收敛速度较慢、易陷入局部最优的问题,提出了一种鲸鱼-蝙蝠算法(WOA-BAT)。首先,建立微电网优化调度模型,在模型中引入BAT算法对WOA算法进行优化;其次,将鲸鱼觅食行为和蝙蝠搜索策略相结合,将WOA-BAT算法用于仿真微电网并网模式下的多目标优化调度。仿真结果表明:WOA-BAT算法相比于传统的WOA、BAT和粒子群优化算法(PSO),能有效提高微电网日运行总效益及系统运行稳定性。
