Upon the basis of the design of the electrode for blisk EDM finishing,the searching of an interference-free path for feeding an electrode through twist channels of a rimed blisk is carried out, in which the ker-nel problem is the determination of the electrode kinematic constraints.

在涡轮叶盘EDM精加工中电极的设计的基础上，进行了电极在带冠叶盘弯扭狭窄通道中无干涉进给轨迹的搜索，其中的核心问题是电极运动约束条件的确定。

The content of nitrate in the leaves in treatment 1 and the treatment with 50% white clover plus little ammonium sulphate as base fertilizer were lower and the soluble sugar higher than that in other fertilizer treatments, which indicated that the B. chinensis quality in that both treatments were superior to pure chemical fertilizer treatments.

同等氮量下，基肥全部用白三叶的处理，生菜的株高、叶宽、叶片数、地上部鲜重和地下部鲜重均显著高于对照，基肥减少50％白三叶用量的处理在追肥前生菜的生长与对照相比无显著差异，追施复合肥后生菜生长显著优于对照，株高、叶宽和地上部鲜重显著优于基肥全部用白三叶的处理。

Culm sheaths glabrous or only hairy below blade, apex asymmetrically triangular; ligule 1–2 mm; foliage leaf blade abaxially sparsely villous or subglabrous

Based on the principle of Hamilton, dividing the main blade, flexbeam and torque tube into several beam elements, the bearingless rotor is nonlinearly modeled in this paper through modal transformation. By Newton-Raphson iteration and temporal finite element method, the above nonlinear equations are solved.

将无轴承旋翼的主桨叶、柔性梁和套管3个部分各自离散成若干梁单元，并将桨叶运动的物理坐标转换为挥舞、摆振、扭转方向的模态坐标，根据Hamilton原理建立旋翼气弹分析的动力学模型。

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。
