The solution composed by algebraic polynomial with double sine series is used to satisfy the corner conditions.

另外用代数多项式和双正弦级数组成的解来满足角点条件。

If w is a ν-value algebroid function of finite positive order in the unit disk, then there is a point eiθ0, such that w has at most 8ν-6 Borel exceptional values in angular domain Δ(θ0,δ).

对于单位圆内有穷正级ν值代数体函数w，必存在点eiθ0，使w在角域Δ(θ0，δ)内的Borel例外值之个数至多为8ν-6。

In order to reduce the maximum combustion pressure and the NO, emission, it adopts smaller advance angle of fuel delivery. In most conditions, the combustion starts after TDC; the maximum rate of pressure rise, the combustion pressure and the heat release rate are lower; their relevant phases are retarded.

结果表明，为降低最大燃烧压力及NO、排放，小缸径直喷增压柴油机采用的喷油提前角较小，柴油机在大部分工况下，燃烧始点较迟，最大压力升高率、最大燃烧压力较低，其对应相位较迟，放热规律也较低。

Results The pain spots were commonly located at the superior angle and medial border of scapula,and the transitional zone between neck and shoulder in trapezius. After 1 to 5 blockings of these pain spots,90.27%（946/1048）patients with cervical syndrome achieved a satisfactory efficacy.

To more briefly calculate the accurate solution of the hangingpoint motion parameters of the beampumping unit,the walking beam's swing equation according to the geometry relationship and movement characteristic of the four pitmen mechanism in the beampumping unit is found.

根据游梁式抽油机四连杆机构的几何关系和运动特点，建立了游梁的摆动方程，并由该方程得出了游梁摆角变化规律以及悬点运动的位移、速度和加速度的计算公式，从而给出了求游梁式抽油机悬点运动参数精确解的一种计算方法。

The lift course of hanging device on wheat no-tillage planter was simulated by using the software of ADAMS. Some important parameters were obtained such as height of the working part relative to ground, the distance between the working part and the rear wheel of tractor, the angle of road pass and the force of hanging point, etc. The key parameters of the hanging device and its best working parameter of hanging device were found out through optimization simulation. Simulation results showed that suspension point had minimum force when variable DV_1 and DV_2 gained corresponding maximum and minimum at scope of structure limit.

应用ADAMS软件对小麦免耕播种机悬挂机构提升过程进行了动态仿真，得到了工作部件的位置高度、工作部件与拖拉机后轮之间的间距、路面通过角以及悬挂点的受力等参数，找到了悬挂机构的关键参数，通过优化仿真，得到了悬挂机构的最佳工作参数，仿真结果表明，设计变量DV_2、DV_3在结构受限范围内分别取其最大值和最小值，悬挂机构悬挂点受力最小。
