At the same time,the specific genes of WG-001 had not lost and the horizontal transfer of the characteristic genes(cry1Aa and cry1Ac of WG-001,and gfp of 1125BG) had not been detected from the genetically engineered B.thuringiensis to the indigenous microorganisms or potted Chinese cabbages.
Besides, the other part of this research suggested that there is another way of Wolbachia horizontal transfer that uninfected parasitoid wasp can be infected by Wolbachia harboured in its infected host.
Two sows with field hog cholera virus (HCV) ,thirty-five piglets stem from the two sows and six HCV negative controls were studied. Observation of development of fetuses,survival rate of piglets, HCV vertical transfer rate, and influence of immune protection efficacy of hog cholera lapinization virus (HCLV) in pigs with HCV were carried out in the laboratory. Meanwhile, HCV horizontal transfer between pigs and influence on ability of sows' reproduction by HCV persistent infection were observed.
and acc ording to the basic knowledge that the Froude number critical value of wind clim bing flow and circling flow in valley is about 1.0, the influence of height of h ill、intensity of inversion and ground horizontal wind speed on Froude number an d horizontal transfer, and dynamic distribution characteristics of Froude number with intensity of inversion and ground horizontal wind speed with several assum ed heights of hill are revealed.
The numerical experiments show that the integrating of surface flux formed horizontal transfer of lower tropospheric jet is one main reason of the severe precipitation with shear line or quasi-stationary front in summer.
On the other hand, if the following typical conditions, a slow moving anticyclone at the upper atmosphere, continuous inversion below 300 m and wind field near the surface unfavorable for horizontal transfer, exist simultaneously, then there will be the period of heavy pollution in Beijing.
Five types of experiments are designed to further reveal the characters of additional stress system. They are experiments of additional stress distribution (including the distribution in even soil, in soil with hardcore and with extension loaded areas), transfer (vertical and horizontal transfer), Chaos, its affect to soil dynamic character and validating experiment.
Based on a linear mode of primary training plane,horizontal transfer function and lateral transfer function of airplane are established,then uncertainty of mode parameter is analyzed,parameter of PID controller is optimized by using NCD module of MATLAB,and height holding mode and head holding mode of airplane autopilot are designed.
