1·A pressure regulation screw bolt can be arranged on the pressure spring, and the pedals can also be installed on the lateral part of the casing.

它的压力弹簧上还可设置压力调节螺栓，外壳侧部还可设脚踏板。

2·Regulation of the spark gap is convenient with sliding rods under spring tension.

放垫沟槽的调节装置也很便于将棒放入弹簧下。

3·The dynamically seasonal regulation of absorbing dust capability of most green tree species in the same location was what is higher in spring and autumn, and what was lower in summer.

同一地点大部分绿化树种滞尘能力的季节动态规律是春秋季较高，夏季较低。

4·The influence of the parameters of the valve(in particular the spring rigidity of the valve rod) on flow-dividing accuracy is analysed in the rate of self-regulation and the steady-state error.

从快速性和稳态误差二个方面，分析了元件参数（特别是阀芯定位弹簧刚度）对分流精度的影响。
