祖国,这是个多么神圣的称呼! 人们亲切地把祖国比喻为母亲,因为无论谁,都是祖国的山林水土养育。对于少年儿童,祖国大地就是他们的摇篮。在这个幸福的摇篮里,他们沐浴着阳光雨露,茁壮成长。要唱好这首二部合唱歌曲,可先让学生知道一点有关音程、和声的简单知识,再分为二个声部,作三度、四度、六度音程的演唱训练,然后学唱。演唱时要唱得亲切、轻巧,有休止符的地方,停顿要干净。

Corona discharge, as a common means to obtain non-equilibrium plasma, can generally obtain high-concentration plasma by increasing discharge points to meet production needs. However,the existing numerical simulation models used to study multi-point corona discharge are all calculations of small-scale space models, which cannot obtain the distribution characteristics of plasma in large space. Based on our previous research, this paper proposes a hybrid model for studying the distribution of multi-point discharge plasma in large-scale spaces, which divides the computational domain and computes separately with the hydrodynamic model and the ion mobility model. The simulation results are verified by a needle–ball electrode device. Firstly, the electric field distribution and plasma distribution of the needle electrodes with single tip and double tips are compared and discussed. Secondly, the plasma distribution of the needle electrode with the double tip at different voltages is investigated. Both computational and experimental results indicate that the charged particle concentration and current of the needle electrode with double tips are both twice as high as those of the needle electrode with a single tip. This model can extend the computational area of the multi-point corona discharge finite element model to the sub-meter(25 cm) or meter level, which provides an effective means to study the plasma distribution generated by multiple discharge points in large-scale space.

三轴振动激励下悬挂座椅垂向传递率试验研究

声学学报 2024年第2期49卷 209-216页

作者：尹玮倓邱毅浙江大学能源工程学院杭州310058 南安普顿大学工程与物理科学学院英国南安普顿SO171BJ

针对三轴激励下无源空气弹簧悬挂座椅垂向振动传递特性进行了试验研究。其中,垂向激励幅值设置为0.25 m/s^(2)r.m.s.、0.5 m/s^(2)r.m.s.或1.0 m/s^(2)r.m.s.,纵向和横向激励幅值同为0 m/s^(2)r.m.s.、0.5 m/s^(2)r.m.s.或1.0 m/s^(2)r.m.s.;座椅靠背倾角设置为0°、10°或20°。研究表明,垂向和水平方向振动激励幅值的增加均引起悬挂座椅传递率共振频率的降低,并影响座椅有效幅值传递率;在较小幅值(0.25 m/s^(2)r.m.s.)的垂向振动激励下,靠背倾角对该共振频率也有一定影响。此外,垂向和水平振动幅值对座椅传递率的影响存在轴间耦合效应,当垂向振动的幅值增大时,水平振动幅值从0.25 m/s^(2)r.m.s.增大到1.0 m/s^(2)r.m.s.所造成的传递率峰值的变化程度将减小,反之亦然。

基于空间数据和属性数据,构建了汉江安康断面以上流域环境水文预测(HYPE)模型,模拟了2012—2016年安康水文站的降水量和径流以及研究区非点源总氮、总磷污染负荷。结果表明:HYPE模型日径流量和月径流量模拟结果率定期纳升效率系数分别为0.78、0.90,验证期分别为0.69、0.87;总氮、总磷负荷模拟结果率定期纳什效率系数分别为0.71、0.69,验证期分别为0.68、0.63,表明HYPE模型在研究区具有良好适用性;汉江安康断面以上流域总氮和总磷非点源污染负荷主要集中在6—10月,主要来源于农业化肥施用与水土流失;研究区总氮单位面积负荷流失量为0.354~6.139 kg,总磷单位面积负荷流失量为0.012~0.395 kg,总氮、总磷流失最严重的区域主要分布在流域偏南部,合理使用化肥、加强防治水土流失是控制研究区非点源污染的有效措施。
