The result indicated, In the MS culture medium, and the damagement increased with Pb(superscript 2+) concentrition, when Pb(superscript 2+) concentration was up to 1000μmol/L, the callus was geatly damaged and its character is small, hard, skin drying; Organic acid of suitable concentration was able to improve the induction and growth of rice callus under the Pb(superscript 2+) stress, i.e. ascorbic acid, critic acid and oxalic acid The effect was the best which added 750 mol/L citric acid in MS culture medium, the callus was fresh, light yellow, loose, the surface moist. and survival was as higher as controlled treatment.

而添加不同有机酸（抗坏血酸、柠檬酸和草酸）均可明显改善Pb(上标 2+)胁迫下愈伤组织的生长，尤以750μmol/L柠檬酸对Pb(上标 2+)毒害的缓解效果最佳，其愈伤组织块颜色浅黄，表面湿润，愈伤组织成活率高，与对照愈伤组形态较接近。

RESULTS Duodenal ulcer was the first cause of upper gastrointestinal hemorrhage. Gastric ulcer, cirrhosis, Mallory-Weiss syndrome or acute gastric mucous lesion was the second cause of the illness alternatively. The rate of endoscopy and emergent endoscopy has been going up year after year and got up to 80% in 1998. Bleeding and active hemorrhage, respectively were found in 24.3% and 14.9% of the patients underwent endoscopy before medication. Endoscopic hemostasis was performed in 108 patients by spraying hemostatics and a good response was achieved subsequently. Hemostatics were mainly cimetidine and yunnan baiyao before 1994. Reptilase, pPI, famotidine and ranitidine were used increasingly while cimetidine and yunnan baiyao were used decreasingly. Octreotide was used in patients with cirrhosis commonly. The length of hospital stay and the period from admission to bleeding cease tended to be shorter year by year, but the reduction rate was small. The uses of ranitidine, famotidine, pPI, reptilase, octreotide, early endoscopy and endoscopic therapy may play a role in improving the therapeutic effect of hemostasis, reducing the hospitalization and the mortality.

结果 十二指肠球部溃疡是历年上消化道出血的首要原因，胃溃疡、肝硬变、Mallory -Weiss综合征、急性胃粘膜病变则交替成为第2位出血原因；内镜诊断率和急诊内镜率逐年提高，1998年达到80%，内镜下见出血者占内镜检查的24.3%，而见到活动性出血者仅占内镜检查者的14.9%；内镜下止血108例次，成功率100%；1994年前治疗药物主要为云南白药和甲氰咪胍，之后，随着立止血、质子泵抑制剂、法莫替丁、雷尼替丁等药物使用的逐渐增多，前二者的使用逐渐减少，善得定多用于肝硬变出血；住院天数和止血天数呈逐年下降的趋势，但幅度微小；雷尼替丁、法莫替丁、PPI、立止血、善得定的使用以及及时的内镜检查和内镜下治疗在提高止血效果、缩短住院天数、降低死亡率方面可能起到了一定作用。

Secondly, the method of hierarchical classification was adopted to divide 282 cities into 3 kinds, the first was mainly capital cities and vice-province cities; the second was mostly eastern coastal cities and some middle cities; the third was western cities and part of middle cities. Thirdly, principle component analysis was taken to get the numbers of principle component, dedicative ratios of each principle component, and indicator values of each kind of cities, then, the differences of numbers of principle component, dedicative ratios of each principle component, and indicator values of each kind was investigated.

然后采用层次聚类分析的方法将282个地级城市分成了3类，采用主成分分析的方法分别对每一类型城市进行分析，得出每类型城市主成分的组数、每组主成分的贡献率及指标的因子值，分析了各类型城市主成分及指标因子值的差异。

Of the free tick, Hyalomma asiaticum asiaticum was the dominant species in the southern part while Hyalomma asiaticum kozlovi was the dominant species in the eastern part.Both of them accounted for about 66.9% and about 25% was overlapped. Among the parasitic ticks, Rhipicephalus turanicus was the dominant species and its proportion was higher than that in the northwest.The proportion of Rhipicephalus sanguineus reached about 10%,which was identical to Dermacentor niveus .

游离蜱中亚洲璃眼蜱指名亚种在南部地区占主要地位，为72.6%，而在东部地区以亚东璃眼蜱为主，为66.9%，存在25%左右的交叉，寄生蜱中以图兰扇头蜱为主，并较西北部的比例偏高，血红扇头蜱的比例达10%左右，与银盾革蜱基本一致，较西北部高出20左右。

But I was not content with this Discovery; but having now more Courage, and consequently more Curiosity, I takes my Man Friday with me, giving him the Sword in his Hand, with the Bow and Arrows at his Back, which I found he could use very dextrously, making him carry one Gun for me, and I two for my self, and away we march'd to the Place, where these Creatures had been; for I had a Mind now to get some fuller Intelligence of them: When I came to the Place, my very Blood ran chill in my Veins, and my Heart sunk within me, at the Horror of the Spectacle: indeed it was a dreadful Sight, at least it was so to me; though Friday made nothing of it: The Place was cover'd with humane Bones, the Ground dy'd with their Blood, great Pieces of Flesh left here and there, half eaten, mangl'd and scorch'd; and in short, all the Tokens of the triumphant Feast they had been making there, after a Victory over their Enemies; I saw three Skulls, five Hands, and the Bones of three or four Legs and Feet, and abundance of other Parts of the Bodies; and Friday, by his Signs, made me under stand, that they brought over four Prisoners to feast upon; that three of them were eaten up, and that he, pointing to himself, was the fourth: That there had been a great Battle between them, and their next King, whose Subjects it seems he had been one of; and that they had taken a great Number of Prisoners, all which were carry'd to several Places by those that had taken them in the Fight, in order to feast upon them, as was done here by these Wretches upon those they brought hither.

我做出一想到这种罪恶勾当就要呕吐的样子。然后，我向他招手，叫他马上走开。他立即十分驯服地跟着我走了。我把他带到那小山顶上，看看他的敌人有没有走。我拿出望远镜，一眼就看到了他们昨天聚集的地方。但那些野人和独木舟都不见了。显然他们上船走了，并且把他们的两个同伴丢在岛上，连找都没有找他们。我对这一发现并不感到满足。现在，我勇气倍增，好奇心也随之增大。因此，我带了我的奴隶星期五，准备到那边看个究竟。我给了他一把刀，让他拿在手里，他自己又把弓箭背在背上--我已经了解到，他是一个出色的弓箭手。另外，我还叫他给我背一支枪，而我自己则背了两支枪。这样武装好之后，我们就向那些野人昨天聚集过的地方出发了，因为我很想获得有关那些野人充分的情报。一到那里，呈现在我面前的是一起惨绝人寰的景象，我血管里的血不由得都冰冷了，连心脏也停止了跳动。那真是一幅可怕的景象，至少对我而言实在惨不忍睹，可是对星期五来说，根本不当一回事。那儿遍地都是死人骨头和人肉，鲜血染红了土地；那大片大片的人肉，有的吃了一半，有的砍烂了，有的烧焦了，东一块西一块的，一片狼藉。总之，到处都是他们战胜敌人之后举行人肉宴的痕迹。我看到一共有三个骷髅，五只人手，三四根腿骨和脚骨，还有不少人体的其他部分。

到了洞里，我给他吃了些面包和一串葡萄干，又给了他点水喝。因为我见他跑了半天，已经饥渴不堪了。他吃喝完毕后，我又指了指一个地方，做着手势叫他躺下来睡一觉。那儿铺了一堆干草，上面还有一条毯子，我自己有时也在上面睡觉。于是这个可怜的家伙一倒下去就呼呼睡着了。

Methods Marshland areas near high endemic villages of schistosomiasis in the Poyang Lake region were selected. Corresponding map was digitized and (Landsat 5 TM) the image was corrected according to the digital map. The image where water and land shifted during floody and dry seasons was extracted and classified by unsupervised method. The image in dry seasons was calculated by both Normalized Difference Vegetation Index and Tasseled Cap model. Traditional snail survey was done at the same areas and recorded the geographic position by Geographic Position System. Some cultured lands inside the embankment and water pound in marshland areas were selected as control group. Results The image of pilot areas was classified into 10 classes.

方法选择鄱阳湖区内3个洲岛型血吸病重度流行村周围的洲滩地图进行数字化，在数字化地图的基础上分别对两张Landsat 5TM卫星遥感片进行校正，并提取出冬陆夏水洲滩部分，运用ERDAS IMAGINE软件对此洲滩进行计算机非监督分类、校正植被指数(Normalized Difference Vegetation Index， NDVI)和穗帽湿度变换指数(Tasseled Cap， TC)模型计算；用传统方法进行螺情调查，卫星定位仪记录有钉螺点的经纬度，同时选择部分堤内的农田和水溏作为对照点。

By the The equipment,The ratio in use of resin was increased inside VC manufacture , less acid, alcali and water was spend, The operator make less error then before due to automatization level was increased. So the production level of the gulonic acid was increased,The cost price of the gulonic acid was reduced, It is very important to increase greatly the economic effectiveness of the enterprise.3, Finished the industrialization apparatus design and feasibility studies, and the new technical equipment was run triumphantly in industrialized production.

使用该设备系统可提高VC生产中提取工序的树脂用率，减少树脂使用过程中的酸、碱及水的消耗，同时自动化水平提高，人为失误减少，最终可提高古龙酸的生产水平，降低古龙酸的生产成本，对大幅度提升企业的经济效益有重大意义。3、完成工业化装置设计及可行性研究，并推上了生产。
