Soil and water conservation protective cultivation is an advanced cultivation technology that avoid cultivation or few cultivation on farmland and with stubble cover.Protective cultivation technology is an integration technology that use stubble cover,no-tillage cultivation,deep-plough with machine,and weeding with chemistry.Adopting soil and water conservation protective cultivation can reduce the loss of soil and water in northeast blackland area and improve the soil anti-erodibility.

中文摘要：水土保持保护性耕作是对农田实行免耕少耕，并用农作物秸秆残茬覆盖地表的一项先进耕作技术，保护性耕作技术是由秸秆覆盖、免耕播种、机械深松和化学除草等核心技术组成的一项集成技术，采用水土保持保护性耕作措施可以有效减少东北黑土区的水土流失，提高黑土区土壤抗蚀性。

The grids can be densified locally where the flow is complicated for the sharp change of water depth.(5) 2-D hydrodynamic equations in the generalized curvilinear coordinates have been derived with the contravariant velocities as main variables. The new equations keep the original styles and physical meanings. Based on the water depth correction method, the 2-D flow numerical model has been established and validated by the measured data.

推导了广义曲线坐标系下以逆变流速张量作为主变量的二维水动力方程，新方程保持原有结构形式及物理含义，采用水位校正法建立了二维水流数学模型，经实测资料验证后的模型，模拟并分析了分流角度、宽深比等因素变化对分汊流平面二维水流结构的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
