Sorrow is God's plowshare that turns up and subsoils the depths of the soul, that it may yield richer harvests. 忧愁是神的犁头,掘到土的深处,地就能多结果子。
Above all, we now first meet the iron plowshare drawn by cattle, which made large-scale agriculture, the cultivation of fields, possible, and thus created a practically unrestricted food supply in comparison with previous conditions. 首先,我们在这里初次看到了带有铁铧的用牲畜拉的犁;有犁以后,大规模耕种土地,即田间耕作,从而食物在当时条件下实际上无限制地增加,便都有可能了;
The data showed that the maximum load was on the plowshares spade, and the minimum load was in the area of the transition from plowshare to the wall. 测试结果表明,该测试手段满足使用要求,其数据表明最大点荷载产生于犁铧的铧面上,最小点荷载产生在犁铧与犁壁的过渡区域。

The Effect of Magnetized Plowshare Upon Tillage Performances 犁铧磁化对耕作性能影响初探
Experimental Study on Abrasion Course of Plowshare Edge 犁铧刃口磨损规律的试验研究
Application of in-situ synthesis of nickel-based anti-abrasion coating by argon-arc cladding on plowshare 氩弧熔覆原位合成Ni基耐磨层在犁铧上的应用
According to the fact that there are plenty of capillaries in tillage soil and the plowshare cuts off the soil capillaries when cultivation, the capillary negative air pressure was produced on the interface of soil-moldboard, and its formulation was given. 结合土壤含有丰富毛细管的事实和耕地时犁铧切断土壤毛细管的过程分析,证明了土壤犁壁界面存在由弯月面的附加压强产生的毛细负压,同时给出了毛细负压产生的判定式。
The microstructure and anti-wear mechanism and the feasibility of cladding coatings used to manufacture and remanufacture of plowshare were analyzed. 分析了熔覆层组织结构、熔覆层的耐磨机理及熔覆层用于犁铧制造及再制造的可行性。
The Effort Analysis of Plowshare Blade and Its Application 犁铧刃口的受力分析及其应用
Above results show that we can study further stick resistance on the coated plowshare iron. 说明在犁铧钢表面涂覆某些涂层可以减粘降阻,有待进一步研究。
Simulate the water film formation conditions at the time of tillage parts touching soil, tested the optimal combination of etching Plowshare Steel surface contact angle. 模拟耕作时触土部件形成的水膜条件,测试了刻蚀的最优组合的犁铧钢表面的接触角。
In the tests select the plowshare iron ( hydrophilic material) as a pilot test material, use machine tools to cut and polish the surface of plowshare iron in order to increase the reliability and comparability of tests. 犁铧钢是农机具耕作部件的主要材料,选择犁铧钢(亲水性材料)作为试验试材,运用机床对犁铧钢切割和表面磨光,增加了试验可靠性和对比性。
