查询词典 influence machine

In order to prevent wheat stem lodging and to fertilize precisely, the experiments on the influence of phosphate and potash fertilizers on mechanical properties of wheat stem were performed with Zhengzhou-wheat 9023 as an object. Mechanical properties (such as flexural strength and flexural rigidity) of second base inter-node were measured by six treatments at five growth stages of wheat, which were jointing stage, booting stage, flowering stage, grain-filling stage and maturity stage. Nonmetallic material testing machine was used in the experiments.

为了对小麦精准施肥，提高小麦的抗倒伏能力，该文以郑麦9023为研究对象，磷钾肥配施共6个处理，分别在小麦拔节期、孕穗期、扬花期、灌浆期、成熟期等5个生长期，利用非金属材料万能试验机，对去鞘茎秆作3点弯曲试验，测试茎秆基部第2节间的弯曲强度和抗弯刚度。

The reaction and influence involving the mechanism of crystal and the interior flow field was developed when impeller machine transferring bittern .Based on the measurement through PIV and numerical simulation,the reason that deposition mass rate and removal mass rate is changed along with the increase of crystal layer was analyzed. Moreover,the viewpoint was developed that the change is the result of the reaction among temperature gradient,velocity gradient,turbulent intensity and the temperature stress within the crystal layer.

提出叶轮机械输送卤水时，结盐过程与内部流场相关且相互影响、相互作用，并在进行PIV内流测试和数值模拟的基础之上，综合运用多学科理论，依据Kern-Seaton模型，分析了沉积率与脱除率随盐析层增长而发生变化的原因，提出了这种变化是温度梯度、速度梯度、湍动度及盐析层内部温度应力等各种因素交叉影响的结果。

Aiming at the engineering problem that K welding machine is used to weld PD3 60kg/m rail during welding production at present, the quality of the joint falls short of the standard of TB/T1632-91 because of the objection of grey-spots in the welding joint, this paper analyses the element which influence the welding joint quality in detail from the stability of flash of the accelerating step of the rail, finds out the relationship between the stability of flash-butt welding and the quality of rail joint, provides the measure for controlling the quality of rail welding and some gist for establishing perfect controlling system of welding joint quality

针对目前焊轨生产中采用K型焊机焊接PD3 60kg/m钢轨，接头灰斑缺陷多，性能难以达到部颁标准要求的工程问题，对材质、焊接电压、焊接工艺对接头质量的影响进行研究，并从钢轨焊接加速烧化阶段的闪光稳定性入手，详细分析了影响接头质量的因素，找出了钢轨闪光焊稳定性与质量的关系，提出了控制钢轨焊接质量的措施，为建立完善的焊接质量控制体系提供了依据。
