The demand valve being built in the hydraulic steering circuit can provide a constantly large flow for the centre articulated vehicles to ensure them to keep a good steering performance at low speed, and not go so far as to make steering out of control when the diesel engine runs idle. To make the demand valve work as designers required, all given conditions for the displacements of steering pump and switch pump should be satisfied and the parameters involving the geometry and configuration of the steering...

The demand valve being built in the hydraulic steering circuit can provide a constantly large flow for the centre articulated vehicles to ensure them to keep a good steering performance at low speed, and not go so far as to make steering out of control when the diesel engine runs idle. To make the demand valve work as designers required, all given conditions for the displacements of steering pump and switch pump should be satisfied and the parameters involving the geometry and configuration of the steering cylinder have to be taken into consideration as well. In this paper, the abovementioned parameters have been studied, and the formulas for design and calculation are also presented.

在液压回路中设置双泵稳流阀,可使中央铰接车辆在低速运行时能获得恒定的大流量,保证机器有良好的转向性能,不致因发动机怠转而失去对转向动作的控制。但是要使该阀按照设定要求进行工作,转向泵及辅助泵的排量就必需满足一定的条件,同时还必须考虑到转向缸的几何尺寸及结构布置等参数。本文对上述参数作了分析研究,并为设计工作提供了计算公式。

The active perovskite--LaMnt-xCuxO3 for CO oxidation has beeninvestigated by XPS. For both the clean surface and the adsorbed surface, the measured binding energy of the core level of constituents showed no any significant shift in the range 0≤x≤0.6. The concentrations of oxygen and lanthanum did not vary with the x value, and they kept a good stoichiometry. The concentration of copper with different x values at the outmost layer almost kept constant for the clean surface, and its amount was much...

The active perovskite--LaMnt-xCuxO3 for CO oxidation has beeninvestigated by XPS. For both the clean surface and the adsorbed surface, the measured binding energy of the core level of constituents showed no any significant shift in the range 0≤x≤0.6. The concentrations of oxygen and lanthanum did not vary with the x value, and they kept a good stoichiometry. The concentration of copper with different x values at the outmost layer almost kept constant for the clean surface, and its amount was much lower than that of the bulk concentration, but copper segregated considerably at the very surface by the adsorption. The situation of manganese was just reversed. The Cu (2p) spectra from the adsorbed surfaces showed some huge satellites which features were quite similar to those of CuO, the shake-up mechanism was not easy to be assigned. Copper was confirmed to be the active centre, and the action of manganese was showed by a fairly large energy shift of Mn(2p) caused by the adsorption. The C(1s) spectra indicated two separate peaks, this was consistent with the complex Cu (2p) spectra due to the adsorption. The La (3d5/2) spectra could be synthesized with three peaks. It meant that there were two satellites other than the one which usually regarded. The La(3d) spectra also implied that the effect of lanthanum might not be ignored in the chemisorption of CO. In the valence band obtained by XPS, the peak positions of the O(2p) and the VBM's could show a firm correlation with the catalytic activity which depended on the x value.

用XPS研究了LaMn_(1-x)Cu_xO_3的表面性质。实验表明对0≤x≤0.6,芯态谱能够清楚地区分最表面层和次表面几层的电子结构。组成元素中的氧和镧的含量不随x值而变化,二者维持很好的化学组成比。铜和锰在最表面单层的x值与次表面的有很大差别。清洁表面存在锰的富集。对(CO)吸附表面,情况相反。吸附的碳存在两个谱峰,这与吸附表面的复杂的铜谱相对应。对镧谱的分析得到两个伴峰,而不是通常认为的一个伴峰。价带谱的O(2p)峰位和价带顶与催化活性有一定的对应关系。

How to evaluate the efficiency of energy dissipation still is an unsolved problem, especially for 3-dimensional flow. In this paper are suggested three design criteria of energy dissipation, i.e. rate of energy dissipation, ratio of max. discharge per unit width at downstream end of apron to that just at gate section and the vertical velocity distribution factor. By analyzing data from a lot of hydraulic modeling, it is found that the rate of energy dissipation for 3-dimensional flow is 15% greater than for...

How to evaluate the efficiency of energy dissipation still is an unsolved problem, especially for 3-dimensional flow. In this paper are suggested three design criteria of energy dissipation, i.e. rate of energy dissipation, ratio of max. discharge per unit width at downstream end of apron to that just at gate section and the vertical velocity distribution factor. By analyzing data from a lot of hydraulic modeling, it is found that the rate of energy dissipation for 3-dimensional flow is 15% greater than for 2-dimensional flow and keeps a good relationship with Froude Nunmber at section before hydraulic jump. The laterally flow expanding is another important process of energy dissipation, which has been verified both theoretically and experimentally.

如何评价闸坝下游的消能效果,尤其是三元流情况下的消能效果仍是一个没有解决的问题。本文建议供设计时采用的三个消能指标:消能率,闸门开启时护坦下游端的最大单宽流量与闸孔最大单宽流量之比,垂直流速分布系数。根据大量模型试验资料分析,认为三元流的消能效果比二元流高15%,并与佛劳德数有良好的相关关系。理论和实践都证明,横向水流扩散亦是一种重要的消能过程。
