In the present work about forty antibiotics were tested for their toxicities on the larvae of the great wax moth,Galleria mellonella,the armyworm,Leucania separata,the cotton bollworm,Heliothis armigera,and the green peach aphid,Myzus persicae.It was found that the antibiotics are rather specific in their mortality effects towards different insect species.When mixed in an artificial diet actinomy-ein D,qingfengmycin,blasticidin S,terramycin and kasugamycin caused relatively high mortality rates on Galleria mellonella.But...

In the present work about forty antibiotics were tested for their toxicities on the larvae of the great wax moth,Galleria mellonella,the armyworm,Leucania separata,the cotton bollworm,Heliothis armigera,and the green peach aphid,Myzus persicae.It was found that the antibiotics are rather specific in their mortality effects towards different insect species.When mixed in an artificial diet actinomy-ein D,qingfengmycin,blasticidin S,terramycin and kasugamycin caused relatively high mortality rates on Galleria mellonella.But for the armyworm and the cotton bollworm only blasticidin S was effective when the solution was applied to the corn and cotton leaves respectively,and for Myzus persicae qingfengmycin was better than blasticidin S.The factor causing mortality in different insect species has been tested and discussed.

Since 1974 the research work on gas soft nitriding of nodular cast iron crankshafts used in agricultural diesel engine has started. It has been a success and applied in production through the tests once and again for several years.After being treated by the method mentioned above, the bending fatigue strength of the nodular cast iron crankshaft is increased by 45-70% in comparison with those in normalized condition. The wearing resistance of the treated crankshaft is improved notably; the percentage of broken crankshafts has been greatly decreased from 0.5-2% to less than 0.05%, and the duration for first major overhaul of treated crankshafts has also been prolonged from 1000-1500 hrs. to 5000 hrs. or more. Therefore both the quality of nodular cast iron crankshafts and its practical application effect have been great increased.In this paper, the main test results of the said new technology and its inner principles were emphatically discussed and searched. Meantime the application conditions in production were also described briefly.

用气体软氮化强化农用柴油机球铁曲轴的研究始于1974年。经过几年的反复试验,现已研究成功,并应用于生产实际。 球铁曲轴通过这种途径强化后,和一般正火状态的曲轴相比,其弯曲疲劳强度提高45~70%,耐磨性也显著提高。从而基本上消除了球铁曲轴的断裂现象,使断轴率从原来的0.5~2%,降低到1/2000以下;而第一次大修寿命由原来的1000~1500小时提高到5000小时,大大提高了球铁曲轴的质量和实际使用效果。 本文着重介绍主要试验结果,也探讨了内部机理,并简要地提供了生产应用等情况。
