Analysing ustiloxins inhibiting plant cell mitosis The inhibition experiment of growth of garlic radicle showed that there were more cells in the telophase stage in the garlic radicle dealed with culture filtrate of Ustilaginodea virens than those dealed with H2O. The cell volume of the former was bigger than that of the latter. So it seemed that ustiloxins could inhibit the cell mitosis, but not in the cell elongation.
毒素对植物细胞分裂的抑制作用分析:用大蒜根尖做抑制试验,发现用稻曲病菌培养滤液处理过的大蒜根尖呈分裂末期的细胞数目明显多于相同条件浙江大学硕士学位论文下对照的数目,抑制率为69%,且细胞明显比对照的细胞大,说明毒素抑制根尖细胞的有丝分裂,但不能抑制细胞的伸长。

The phase of ω0 frequency fluctuates tempestuously. The resonance peaks of flexural and torsional vibrations response are present at 2/3ω0 1/2ω0 1/3ω0 and 1/4ω0 with three kinds cracked rotor models. Near 1/2ω0 frequency, quasi-periodic and chaotic motions maybe appear. Periodic, quasi-periodic and chaotic motions show on alternately when the rotating speed is near to 2/3ω0.Combined step-by-step integral method with traditional transfer matrix method, an increment transfer matrix method is put forward.
研究结果表明:各种故障情况下,华北电力大学博士学位论文弯振和扭振之间都存在祸合关系,但弯扭祸合振动一般不会威胁机组安全运行:在叶片丢失或滑环飞脱故障时,将产生很大的弯振,同时各转子扭振也将被激发出来,它以工倍频和前三阶固有频率为主;在各种电气故障情况下,各转子都很快被激励出较大幅值的扭振来,相应各转子弯振也发生一定的变化,但它的变化明显滞后于扭振,扭振和扭矩主要以前三阶固有频率为主。
