I succeeded in establishing a mycorrhizal symbiosis between S. sinuosa and transformed Ri T-DNA carrot roots for the first time. The S. sinuosa sporocarps were found not to occur as single spores, but were observed to survive in groups of sporocarps in the environment.

利用双重培养方法首次成功培养了S.sinuosa的菌根共生联合体。S.sinuosa不是单个孢子,而是以孢子果的形式存在于自然界中。S.sinuosa孢子果的萌发是从孢子果的四周伸出芽管,在侵染根段的过程中,形成大量的营养孢子。

发射机主体部分在原多普勒水平单偏振模式下不作改动,在速调管放大器高频输出之后增加单/双线偏振转换开关、功分器和移相器。

Periodic fluid pulsation in aeroplane hydraulic piping could induce fluid-construction vibration and lead to fatigue damage. It is impossible to find the error sensor's optimization location because of the pressure standing wave, and the pulsation attenuation effect is not perfect when adopting pulsation attenuation at single point. For this reason, a distributed active control method of fluid pulsation was presented. To avoid stationary point in all aviation states, several fluid pulsation actuators and error pressure sensors were placed along the piping. The second fluid pulsation produced by actuators can counteract the primary pulsation brought by aviation piston pump and make the mean pulsation of whole piping minimum when adopting adaptive feed- forward control and the filtered-X least mean square algorithm.

针对飞机液压能源管路系统中的周期性流体脉动诱发流固耦合振动,导致管路疲劳损伤的问题,针对管路中存在压力驻波特性,在采用单点消振时寻找误差传感器最佳布局位置困难而引起脉动抑制效果不理想的缺点,提出了一种分布式流体脉动主动控制方法,即沿管路不同位置布置多个主动消振阀和误差压力传感器,在任意飞行阶段,避开压力驻波点,以误差压力传感器的脉动测量值为控制目标,采用一种针对周期脉动主动控制的自适应前馈控制法和多通道自适应滤波-X LMS算法,调整控制器参数,使主动消振器产生的次级脉动与管路中的初始脉动相互抵消,达到整个管路中的平均流体脉动最小的效果。
