水稻是世界上最重要的粮食作物之一，在整个生育期中遭到各种病虫害的侵害，其中稻瘟病是世界稻区最严重病害之一，防治稻瘟病最经济有效的措施是培育抗性品种。

The dependence of resistance on the curing temperature illustrated that-codoped BST was capable of exhibiting the positive temperature coefficient effect at low frequency; nevertheless,it might display the negative temperature coefficient effect at other frequencies. The relationships between the resistance and applied voltage revealed that the resistance property of-codoped BST appeared at low frequencies, but its property of capacitive reactance might present at high frequency.

The hardness and wear resistance increase with increasing TiB2 content. Adding about 1.5%Mg in melt restrains the conglobation of the TiB2 particles, which makes the size of TiB2 particle decrease and the distribution of TiB2 particle is more homogeneous. The strengthening effect of TiB2 particles is enhanced and the hardness and wear resistance of composites are obviously improved. The excess Mg decreases the refinement effect of TiB2 particles, but the hardness and wear resistance are improved continuously.

结果表明：反应生成的TiB2颗粒平均尺寸约为0.5 μm，材料的硬度和耐磨性随着TiB2含量的增加而提高；添加1.5%Mg元素可明显细化TiB2颗粒，且使其分布更加均匀，增强TiB2颗粒的弥散强化和细晶强化效果，复合材料的硬度和耐磨性显著改善；过量的Mg元素(3%)会造成TiB2颗粒细化效果的下降，但其硬度和耐磨性能继续得到改善。

There are many kinds of salts in gound water, salt lakes and salty soil in China's western region, and deicer salts have effects on frost resistance and corrosion resistance of cement concrete or corrosion resistance of steel bar in reinforced concete.

我国西部地区地下水、湖水中以及土壤中含有多种盐类，道路除冰盐对混凝土的抗冻性以及耐腐蚀性以及钢筋锈蚀有很大的影响，而混凝土年平均经受的冻融次数对混凝土结构设计具有重要意义。

By analyzing experimental data, some conclusions were made that adding normal loads on silt is not an applied method to raising interface shear resistance, Adding some large grains of debris in slit can strengthen the passive resistance force of the transverse ribs of geogrids, yet reduce the integrated pullout resistance force of geogrids when subjected to low normal loads, the ultimate pullout force can be greatly enhanced by adding normal stress to restrain soil dilatability .

对试验结果比较分析后发现：单纯提高法向荷载来增加格栅表面的摩擦剪切阻力的方法并不适用；在粉土中加入大粒径碎石，可以提高格栅横肋的被动阻力，但在竖向荷载较小的情况下，反而降低了格栅的整体拉拔阻力；施加适当的法向荷载，抑制土体的剪胀效应，格栅整体拉拔力得到了显著增强。
