Objective:To produce low-sugar and high-moisture preserved pachyrhizus; Methods:The relationship of moisture and water activity, numbers of bacterial and mildew were researched. Then water activity was reduced by chitosans with different viscosity-average molecular weights; Results:The number of mildew was a major microbial index of quality-maintaining duration of product. The lower viscosity-average molecular weights of chitosans was, the more water activity reduced; Conclusion:When 9 kD molecular weight,...

目的：为生产低糖、高水分含量番薯果脯；方法：研究果脯中水分含量与水分活度的关系及细菌总数和霉菌数在保温试验中的变化，并采用不同黏均分子量的壳聚糖降低果脯的水分活度；结果：果脯中霉菌数是影响产品保质期的主要微生物指标，壳聚糖的黏均分子量越低，降低水分活度的幅度越大；结论：通过添加0.5%、9kD黏均分子量的壳聚糖，产品水分含量为20%、总糖为26%时，番薯果脯常温放置保值期达到12个月。

Result:①out of 25 patients,17 exhibited myeloma-related bone lesions on radionuclide imaging,the positive rate was 68.0%,ribs and spine were involved most frequently,162 lesions showed high uptake of radionuclide,the lesions lied in ribs appeared as strings of pearls,and those in sternums and vertebrae showed linear high uptake,the other 4 showed decreased radionuclide uptake.②the positive rate on radiography was 68.0%(17/25),which was the same as that on radionuclide imaging,the patterns were osteoporosis,pathological fracture,osteolysis or two or two and above of these appearances, radiography detected more abnormalities than radionuclide imaging in identical sites(162 versus 144),but radionuclide imaging detected more lesions than radiography in ribs and sternums.

结果：①25例患者中，骨显像异常17例，阳性率68.0%，肋骨、脊柱最常受累，162处病灶表现为异常放射性聚集，其中，肋骨病灶呈串珠样，胸骨及椎体病变呈扁平状或线状，4处表现为异常放射性减低；②x线片阳性率68.0%（17/25例），与骨显像相同，主要表现为骨质疏松、病理性骨折、骨破坏或呈混合性改变，共同检测的部位中，x线片检出的病灶总数较骨显像多（162和144），但骨显像检出肋骨和胸骨病灶较x线片多。

Firstly, saltating sand grains in various height layers mostly rotate clockwise; the rate of counterclockwise rotation changes from 16.7 to 33.3% for three different friction wind speed (u*= 0.67, 0.83, and 0.87 m/s). However, their mean rotational speeds were not significantly different, irrespective of whether the grains rotated clockwise or counterclockwise. The mean counterclockwise rotational speeds of sand grains for friction wind speed u*= 0.67, 0.83, and 0.87 m/s were 427, 519, and 604 rev/s, versus 429, 522, and 609 rev/s, respectively, in the clockwise direction.

首先，风沙流中各高度层内跃移沙粒旋转均以顺时针方向为主，逆时针方向旋转的沙粒数仅占总数的16.7-29.5%，但是无论逆时针还是顺时针旋转的沙粒，它们的平均旋转速度几乎没有差别(如u*＝0.67 m/s时，分别为427 rev/s和429 rev/s；u*＝0.83 m/s，分别为519 rev/s和522 rev/s；u*＝0.87 m/s，分别为604 rev/s和609 rev/s)；不同摩阻风速条件下各高度层内沙粒的旋转速度均服从Lorentzian分布。
