关于用桥夹绑扎集装箱利弊的讨论

1984年中远开辟中国至西北欧的集装箱班轮航线的“唐河”轮途经新加坡时，我看到有的集装箱船将顶层的箱子用桥夹(BRIDGE FITTING)将它们横连起来，当时觉得这很可取，于是就增添了此类绑扎器材且立即如法炮制。但在航行中逐渐发觉桥夹利少弊多，我曾请教了几位同行，可是他们却不以为然，可是他们也说服不了我。我见到此后中远的集装箱船愈来愈流行采用桥亮，     

超限箱工属具的技术改造

我公司现有超限箱工属具由转锁和保护套两部分构成。接卸超限箱的工艺流程为 :先将钢丝绳扣的一端通过卡环与岸桥的吊具相连接 ,另一端通过卡环与超限箱专用工属具的转锁连接 ,然后把转锁的锁头竖直放入集装箱的箱眼里后顺时针转动 90°角 ,再把转锁护套放下来进入箱眼并落实 (     

56例胆石核心细菌培养分析

本文报告经手术取出56例胆结石的核心细菌培养实验研究,其中胆囊结石44例,42例培养无菌生长,2例核心培养为大肠杆菌;原发胆总管结石7例,6例培养为大肠杆菌,一例为大肠杆菌及变形杆菌;胆囊加胆总管结石5例(仅送胆囊结石)无菌生长。实验研究结果显示胆管结石细菌培养阳性率高,本组为100％。预防胆系带菌状态及早治疗胆道感染是预防胆管结石的重要措施之一。     

Isolation and Characterization of Microorganisms for Degradation of Minimal Oils and Fats at Low Temperatures

The isolation of microorganisms for biodegradation of minimal fats and oils at low temperatures was reported. By using rapeseed oil as a sole carbon source, six strains were isolated from five kinds of oils/fats-contaminated wastewater, soil, and active sludge. Among them, two strains which show the highest oil removal ratios were identified as Pseudomonas pseudoalcaligenes and Pseudornonas mendocina, respectively. The experiments of orthogonal impact conditions show that the optimal oil degradation condition is at pH 8.0, 5 C and 100 mg/L oil. Under this condition, the rapeseed oil degradation ratios of two strains after 24 hours amount to 92. 6% and 92.0% respectively, whereas the removal ratios of lard decrease to 39.5% and 54.3%.

CATIA应力分析在汽车吊具设计中的应用

为设计出能够满足吊运汽车车体所需要的吊具,文章介绍了CATIA的应力分析功能在汽车吊具设计中的应用。应用CATIA软件建立吊具的数字模型,并应用CATIA的自动网格划分和有限元分析功能对建立的数字模型进行应力分析。根据应力分析结果查找到数字模型上的危险点,并针对危险点对数字模型进行结构改进再进行应力分析,最终设计出满足强度要求的吊具。应用结果表明,CATIA的有限元分析功能具有很大的方便性,极大地提高了设计效率。     

Nine pathogenic fungi of waterhyacinth isolated in China

The native pathogens of waterhyacinth in China, were studied and compared on pathogenicity by Koch＇s postulate. Nine pathogenic fungi, YBH, YBB, YB, YYX, YY, YBA1, YBA2, YBA3 and YYB12, were isolated from diseased waterhyacinth plants, and collected from Zhejiang province and Shanghai. According to cultural characteristics, the nine isolates were preliminarily identified. Isolates YBH and YBB were Collectotrichum sp.; YB, YYX and YY were placed in fungi imperfecti; the isolates YBA1, YBA2, YBA3 and YYB12 were Alternaria sp. The isolate YBH was the highly virulent with a disease index （DI） of 65.28% after one month inoculation. The isolate YBA3 was equily virulent, with the disease index of 6770 after 7 day introduction. These two pathogens appear to have the potential as biocontrol agents and they deserve further study.
