Laser melting deposition process (LMD) is an advanced computer-aided laser additive manufacturing process (LAM). This process can produce net-shape components with fully dense microstructure and good properties based on a computer aided design (CAD) model by using a high power laser to melt the injected powders and re-solidify them in a layered way. It presents obvious superiority in direct manufacturing components with small-lot, repairing high-value components with good performance, and integrated fabricating new materials and composite structure. Deep understanding the melting process, alloying and reaction within the molten pool, solidification behavior, as well as formation and control of residual stress and defects during deposition are crucial to successful application.

旅行医学科学 1997年第4期3卷 151-152页

作者： Lu Yongchang He Jinshen Zhang Jiazhu nantong Health and quarantine bureau, P. R. china

This paper reported 5 Dengue Fever (DF) cases were found among the 9 international travellers, who went to Malaysia, Burma from nantong. In order to obtain the essential conditions, provide the international travellers with knowledge and preventive measures of DF, All of 9 travellers were surveyed by individual interviewing and blood—sample were detected for antibody. According to some epidemiological data, the area where the travellers went was epidemic area of DF, the time they arrived just in epidemic period. The results of individual interviewing showed that during they stayed abroad, they were bited by mosquito and contacted with a person who was suffering from illness, which similar with cold and other symptoms. Combinating the duration of DF with the date of onset, it was inferred that the 5 cases were infected with DF virus in the Burma. The same symptoms and signs of the 5 cases were as follows : the sudden onset with high fever, shivering, intense pains in the joints and muscles, poor appetite, nausea, vomiting and scarlet fever type of rash. Antibody of Dengue—3 were detected in all of the 5 cases, the highest titer was 1 : 10,240, the lowest titer was 1 : 2,560. In view the result of this investigation, authors put forward the following suggestions: (1) enhance the international travellers’ personal preventive consiousness to DF (eg: using mosquito expellant, and applying mosquito net). (2) If the imported cases were found, the isolation should be applied immediately and disinseeting, mosquito control measures also need be applied. (3) As the incidence of DF increased drastically in the most parts of the tropics and subtropics worldwide, especially in present decade, a total cases of DF were more than the total cases of the passed 25 years (1956—1980), meanwhile, considering the insect vectors of DF existed in the some areas in china, the population is susceptible to the DF, the vigilance of occur of DF in china should be caused.
