This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.

The infectivity of TMV recovered by dialysis from incubation with anthraquinone glycosides in vitro has been reduced in contrast to infectivity of TMV control, it seems that anthraquinone glycosides have direct viricidal effect on TMV. The anthraquinone glycosides may interfere recognization of TMV to host receptor when applied before TMV inoculation. The anthraquinone glycosides can inhibit multiplication of TMV in infected leaf discs but did not inhibit infectivity of TMV-RNA in vitro. The control of tobacco mosaic virus disease of N.

总蒽醌甙对TMV混合，对粒体形态无破坏作用，但经透析，其抑制作用仍较高，表明总蒽醌甙与TMV结合能力强不易解离或对粒体具有直接毒害作用；总蒽醌甙预先接种可能影响病毒对侵染位点的识别，对叶圆片中的病毒具有抑制复制的作用，但在体外混合不影响TMV-RNA的侵染活性，可能与总蒽醌甙干扰病毒的衣壳装配过程或影响复制酶的活性有关。

They recommend childproof packaging with striking and clear warning labels; increased public education and media publicity on primary prevention of poisoning; and new legislation mandating safety caps on poison containers. As there is not a specific antidote for amitraz poisoning, management should be supportive and symptomatic.

作者特别提到，amitraz可经由口腔食入或皮肤接触而中毒，但也有经呼吸道吸入amitraz的可能，因此他们建议应设计小孩无法打开的包装，并在包装外标示明显且清楚的警告卷标、加强对大众在这方面的教育及媒体对初期预防的宣导、立法管理盛装毒药的容器安全加盖等，因为目前为止尚无amitraz的解毒剂，因此必须根据中毒者的症状给予支持性治疗。
