患"颤抖病"中华绒螯蟹血细胞中类立克次体寄生的超微结构观察

本文对患“颤抖病”的中华绒螯蟹血细胞内类立克次体生物RLOs的寄生及繁殖特性进行了超微结构研究。正常中华绒螯蟹的血细胞可分为三类；无颗粒细胞、小颗粒细胞、小颗粒细胞和大颗粒细胞，而RLOs只特异性地侵染小颗粒细胞。RLOs以胞吞的方式进入小颗粒细胞，并在细胞内大量增殖形成包涵体，使细胞肿胀、瓦解、坏死，进而释放出RLOs，释放出的RLOs又继续侵染其他靶组织和细胞。     

Multitemporal passive microwave mapping in MACHYDRO'90

MACHYDR0'90 was an experiment conducted in Pennsylvania in 1990 to study the synergistic use of remote sensors in multitemporal hydrologic studies. As part of this mission the pushbroom microwave radiometer was flown and used to produce brightness temperature maps. Verification studies and vegetation algorithms for mixed land cover areas are described

Direct electroless Ni-P deposition on AM50 magnesium alloy from sulfate bath

A bright electroless Ni-P deposition on AM50 magnesium alloy in a sulfate plating bath was proposed by using direct plating process with non-chromate pretreatment. The electroless Ni-P plating on AM50 magnesium alloy has an admirable appearance and good adhesion. The results indicate that the electroless Ni-P deposition with non-chromate pretreatment has better adhesion than that of zinc immersion coating. Anodic polarization curves indicate that the electroless Ni-P deposition obtained from the sulfate bath has similar corrosion-resistance to that obtained from basic nickel carbonate bath. The deposition process generates less pollutant by a non-chromate plating bath and is suitable for the magnesium alloys manufacture because of its low cost. The hardness of the electroless Ni-P plated AM50 is about HV 720.6 and HV 969.7 after heat treatments at 180℃ for 2 h. The wear resistance of Ni-P plated magnesium alloy specimens is about 5 to 9 times as high as that of bare magnesium alloys.
