A lot of research work has been done on the improvement of small wheel tractor traction performance in recent years.

近几十年来，国内外许多学者、专家对如何提高拖拉机的牵引附着性能作了大量的研究，取得了较好的效果。

Wheel tractors, especially small wheel tractors have some well-known disadvantages such as poor traction performance, driving wheel slipping, low traction efficiency and high fuel consumption.

轮式拖拉机特别是小型轮式拖拉机在田地进行重负荷作业时，牵引附着性能差，驱动轮滑转严重，造成牵引效率低、油耗大是普遍现象。

When operated as a bulldozer, a pair of endless track roller frames are free to oscillate up and down about a horizontal axis passing Lhrough the bulldozer's main frame for improved traction and grading characteristics, reduced stress on the tractor stmcturc, and a more comfortable ride for the operator.

In 1941 the Royal Romanian Army ordered 221 of these Czech medium artillery tractors, which with a six-ton towing capacity were ideal all-terrain transports for medium and heavy artillery batteries; however, only 130 were received, the remainder being appropriated by Germany for its own wartime needs.

1941年皇家罗马尼亚陆军订购了221辆这种型号的中型火炮牵引拖拉机，该车具有6吨的牵引能力并能在全地形上使用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
