In order to solve the problem of crop growth difficulty in saline-alkali soil, it is meaningful to discuss how much salt affects the growth and germination of soybean. Zhonghuang 35 with low salt tolerance and Zheng 1311 with high salt tolerance were selected respectively, and NaCl solutions with concentrations of 0.250, 0.250, 0.125, 0.0625 and 0 mol L-1 were set for hydroponics, the effect of NaCl concentration on soybean germination was determined by variance analysis. The results showed that the concentration of NaCl was significantly correlated with the germination rate of Zhonghuang 35 and Zheng 1311 soybean varieties. The health of soybean is inversely proportional to NaCl concentration. The effect of NaCl concentration on germination in Zhonghuang 35 was more obvious than that in Zheng 1311. This study provides a theoretical basis for soybean growth in saline-alkali soil.
为了解决盐碱地作物生长困难的问题,探讨盐分对大豆生长和发芽的影响是有意义的。分别选择耐盐性较低的中黄 35 和耐盐性较高的郑 1311,设置 0.250、0.250、0.125、0.0625 和 0 mol L-1 的 NaCl 溶液进行水培,通过方差分析确定 NaCl 浓度对大豆发芽的影响。结果表明,NaCl 浓度与中黄 35 和郑 1311 大豆品种的发芽率显著相关。大豆的健康状况与 NaCl 浓度成反比。NaCl 浓度对中黄 35 发芽率的影响比郑 1311 更明显。该研究为大豆在盐碱地中的生长提供了理论依据。

The Tilting Method(TM) is applied to measure the automobile mass center position widely for simple principles and easy operations. However, the TM has some problems, such as inaccurate calculation of tire force point and large tilting angle of the vehicle, so the Improved Tilting Method (ITM) is proposed in this paper. In the process of running ITM, the tire force direction is always straight up, so the friction and other adverse factors are less than that in TM. ITM applies a combined parallelogram mechanism to keep the supporting plates horizontal. In this research, we study the ITM measurement process by simulation analysis. The research results show that the design scheme and the equipment movement outcomes prove the feasibility and practicability of the ITM.
倾斜法(TM)因其原理简单、操作方便而被广泛应用于测量汽车质心位置。然而,倾角法也存在一些问题,如轮胎受力点计算不准确、车辆倾角较大等,因此本文提出了改进倾角法(ITM)。在运行 ITM 的过程中,轮胎受力方向始终是笔直向上的,因此摩擦等不利因素比 TM 少。ITM 采用组合平行四边形机构使支撑板保持水平。在这项研究中,我们通过仿真分析研究了 ITM 的测量过程。研究结果表明,设计方案和设备运动结果证明了 ITM 的可行性和实用性。

Insulation mortar was prepared with cement, mud from washing manufactured sand, wheat straw, vitrified microbead, polypropylene fibre and chemical admixture. Influence law of wheat straw on performance of cement insulation mortar was discussed. Influence factors included pretreatment method, dosage and length of straw. Features of straw surface pretreated by NaOH solution and bonding interface were observed by scanning electron microscopy. Dry density, compressive strength, thermal conductivity coefficient reduce with the increase of straw length and the decrease of soak time. When straw dosage increases, they decrease firstly, increase later. Straw reduces the mass loss of cement insulation mortar treated at temperature below 500℃. Straw surface pretreated by NaOH solution becomes rough. There are trenches with widths about a few microns. It makes a better interface combination between straw and cement matrix.
保温砂浆由水泥、洗砂泥、小麦秸秆、玻璃化微珠、聚丙烯纤维和化学外加剂配制而成。讨论了小麦秸秆对水泥保温砂浆性能的影响规律。影响因素包括预处理方法、用量和秸秆长度。通过扫描电子显微镜观察了经 NaOH 溶液预处理的秸秆表面和粘结界面的特征。干密度、抗压强度和导热系数随着秸秆长度的增加和浸泡时间的减少而降低。当秸秆用量增加时,它们先减小后增大。秸秆能减少水泥保温砂浆在低于 500℃温度下的质量损失。经 NaOH 溶液预处理的秸秆表面变得粗糙。出现宽度约为几微米的沟槽。这使得秸秆和水泥基质之间的界面结合得更好。

This paper proposes an open-cell ceramic acoustic material to combat noise pollution, which utilizes sediment from Taihu Lake as its main ingredient. The open-cell ceramic is manufactured using the gel injection molding method to achieve a high occupancy ratio. Simulation and experimental research demonstrate that the open-cell ceramics possess excellent sound absorption properties, particularly in the middle and high frequencies, with high sound absorption characteristics. The unique pore structure of the open-cell ceramics provides multifunctional and excellent mechanical properties, resulting in a lightweight, pore-designable, and broad-frequency sound absorption material that is environmentally friendly, energy-efficient, and renewable.

A lithium-ion battery begins aging since it is made available, with a variety of secondary reactions taking place inside it, and this has an impact on the battery’s safety and performance. Therefore, it is necessary to conduct cyclic aging experiments on batteries under various conditions. In this study, 4 stresses are chosen, ambient temperature (T), constant charging current (i1), end-of-charge voltage (V1), and constant discharging current (i2), with three levels chosen for each stress, and a experimental method is devised for aging batteries, serving as not only the basis for studying the issue about the aging of batteries under the effect of multiple factors, but also the precondition for devising an accelerated battery-aging experiment.

AFM showed the crystal quality of the Films. The results of experiment demonstrate that high-quality films have been achieved by this technique, and research on ZnO films can be done by the equipment.
文中给出了磁控溅射系统的各个部分。同时,我们分析了磁控溅射的工作原理。在生长出纯氧化锌(ZnO)薄膜后,以锌为靶,在 NH3-O2-Ar 气氛中制备了掺杂 N 的薄膜,并以锌和铝为靶,通过共溅射技术生长出掺杂 Al 和 N+Al 的共掺杂 ZnO 薄膜。原子力显微镜显示了薄膜的晶体质量。实验结果表明,利用该技术可以获得高质量的薄膜,并可利用该设备进行氧化锌薄膜的研究。
