Both of the aqueous extract from aerial part and root of T. repens inhibited the germination rate of weed seeds, root activity and respiratory rate, and the activities of superoxide dismutase peroxidase and catalase of germinating seeds; enhanced the activity of peroxidase and the content of malondialdehyde.

结果表明，白三叶草地上部分水浸液和根部水浸液显著抑制苘麻和稗草种子的发芽率，降低了杂草种子萌发过程中超氧化物歧化酶，过氧化氢酶的活性，抑制了杂草种子萌发过程中的呼吸速率，根系活力，明显提高了杂草种子过氧化物酶活性和丙二醛的含量。

It is found that the design of reinforce-beam section dog-bone connection can transfer the yielding joint from flange welds to parent metal zone, which possesses better plasticity and avoid yielding joints in weak welds. This design also enables beam flanges to dissipate earthquake energy more effectuality and protects weak welds.

在弹性、弹塑性有限元分析的基础上，对狗骨式节点和翼缘增强狗骨式节点进行了承载能力对比分析，结果表明：翼缘增强狗骨式节点设计可以将梁柱翼缘焊缝的塑性铰有效的转移到塑性好的母材区域，避免了在薄弱的焊根部位形成塑性铰，保护了韧性较差的焊缝。

The result of experiment on different chemical control shows the best chemicals for cootrol Eriosoma lanigerum in the part trees above ground is 40%omethoate adding 1‰ washing powder (the ratio is 1:800). Applying 0.25 kg fortified benzene to the root of each tree can kill Eriosoma lanigerum in the root. In the past three years, chemical control as first, complementary with the measures of integrated control and quarantine techniques, the percentage of suffered trees in Malus pumila garden of 40.8 hm2 in Yimen County has decreased from 48.5%to 2.65%.

不同药剂的防治试验结果表明：40％的氧化乐果1：800倍液加1％o的洗衣粉是防治苹果地上部分棉蚜的较佳药液；另每株根施0.25kg高丙体内吸粉剂对根部的苹果棉蚜具有较好的杀灭作用。3年来，以化学防治为主，辅以配套的综合防治及检疫技术措施，使易门40.8hm2苹果园的植株受害率由48.5％降至2.65％，取得了较好防治效果。

The results showed that rice straw growth and fascicular alteration interacted when water was deficient. It not only affected the transportation of nutritious substance from rhizine and leaf to kernel, but also led to the decrease of agronomic characters and yield. 4 ecotypes of rice vascular bund...

结果表明：水分不足对稻秆及秆中维管束的影响是相互的：稻秆的发育情况影响了维管束变化，同时维管束的变化影响了稻秆的发育，最终影响营养物质从根部、叶部向籽粒运输，从而使结粒数、稔实率、千粒重、产量下降。4种生态型水稻维管束系统与一次及高次枝梗数目、结粒数、千粒重等有类似的相关性，而且水分不足时反应出相同的结果，说明土壤水分对维管束系统的分化有很大的影响，水分不足将使维管束面积变小，维管束比增大，从而使产量变小。
