There was big difference among the 22 different materials in the disease resistance. Translocation lines Pm97033 showed the highest resistance in reaction than others. The percentage of diseased root and severed level were 11.3% and 5.4%; substitution lines Wan7107 showed medium resistance to the fungus, the percentage of diseased root and severity level were 21.4% and 10.6%; F5 generation of common wheat with Till showed higher resistance to take-all fungus than the PS progenies of common wheat with Aegilops tauschii or the other common wheat varieties.

菌饼＋菌粒法对宁春4号的致病力明显高于菌饼法和菌粒法，其病根率、严重度和病茎率分别达到100.0%，57.3%和28.6%。22个遗传背景不同的小麦材料间抗病性差异较大，其中小麦－簇毛麦易位系Pm97033的抗病性最强，病根率和严重度分别为11.3%和5.4%；代换系Wan7107次之，病根率和严重度分别为21.4%和10.6%；硬粒小麦－簇毛麦双二倍体(TH1)与普通小麦品种杂交后代的抗病性强于粗山羊草与普通小麦品种杂交后代。

But whatever your system is, this ELEMENT CABLE Twisted pair is a definitive bargain : not because it is not expensive, but because it provides outstanding musical results and can compete with cables costing 5 times its price!

但无论你的系统，这个因素电缆双绞线是一个明确的讨价还价：不是因为它不昂贵的，但因为它提供了出色的音乐效果，并能与之抗衡的电缆费用5倍的价格！

The results show that,the control of delaying period-doubling bifurcations and unstable periodic orbits in a chaotic attracter of the AOB system is effectively realized,and other stable periodic orbits 2np、3mp and 2np×3mp are obtained by adjusting the control parameters.

仿真模拟显示，通过选择恰当的控制参数，有效地实现了声光双稳系统中倍周期分岔的延迟控制和混沌吸引子中原不稳定周期轨道的稳定控制，同时，还可以将系统控制在2np、3mp 和2np×3mp这样其它任意所需的周期轨道上。
