The results showed that: different concentrations of sucrose and boric acid had significant impact on pollen germination, but different concentrations of calcium had no significant impact on pollen germination. It was most appropriate for tube elongation when sugar 150 gL^(-1) and boric acid 100 gL^(-1). Lack of sucrose would lead to the accumulation of callose in top of pollen tube and hold back its growth. The distribution of callose was regular in pollen tube when the medium lacked boric.

结果表明：蔗糖、硼酸浓度间对花粉萌发有显著影响，钙浓度间对花粉萌发的促进作用不明显；蔗糖150 gL^(-1)、硼酸100 mgL^(-1)时最适宜花粉管伸长；蔗糖的缺乏会导致胼胝质在花粉管顶端积累，使其生长停滞，缺硼时胼胝质在花粉管内分布正常。

The outside sealing component -corrugated tube of valve can affect outside sealing properties of valve. Through finite element analyse of stress state of corrugated tube, the stress status which are under stretch, compress and stretch-compress action are obtained. Combined with test, the stability, detonation pressure and rigidity of corrugated tube are analyzed. The result showed that corrugated tube is safety under working pressure and when stretch-compress displacement is less than 60% of maxmium displacement.

作为阀门外密封元件的波纹管是影响阀门外密封性能的关键部件，通过对波纹管进行有限元分析，初步掌握了波纹管在拉伸、压缩以及拉伸压缩共同作用下的应力状况，同时采用有限元计算和试验相结合的方法，分析了波纹管的稳定性、爆破压力、刚度等，结果表明，波纹管在工作压力下，拉伸和压缩量达到许用位移的60%时，波纹管工作仍是安全的，为阀门开启量的确定提供了理论依据。
