Based on the problems of low viscosity index and the acidity increasing in the lubricating base oil,it has been found that the unstable quality of the crude oil was the root cause to effect on the quality of the base oil by analysis for long time;the low viscosity index and the higher acidity were resulted from the low paraffinicity and the high content of aromatics,cyclane.

针对润滑油基础油相继出现的黏度指数降低、酸值升高等问题，跟踪分析了润滑油基础油质量，认为原油的变化是造成润滑油基础油质量变化的根本原因；基础油组成中烷烃含量降低，芳烃和环烷烃含量上升是其酸值上升和黏度指数下降的内在原因。

对比 实验表明产生这两类导电轨迹的原因是由于物质对水的结构有促进能力和破坏能力两种不同功能所造成；而电导率持续变化的原因则可能与自然环境某些电磁辐射场强度的持续变化有关连。

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。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果，包括地壳运动，火山爆发，沉积作用，冰河作用和风化等等，在这些作用下，生成了火成岩，火山杂岩，水成岩和沉积岩等，一些矿石是由于这些作用共同形成的，这就是自然界中没有纯净矿石的原因。由于这些原因的存在，需要用分离技术和器械，也就是矿石加工设备对矿石进行的分割，迄今为止这些矿石加工设备已经不能够满足冶金工业的需要，科学家们力图用激光把冶金工业提高到一个新的水平。

Possible reasons for this failure may be that obesity is so physiologically complex that no single gene or even handful of genes is likely to have a dispositive role, that examining gene gene interactions is difficult without large numbers of subjects, and that variations among current candidate genes are not the most important contributors to human adiposity.

其他有明显量的变化的基因很难证明，可能的原因就是肥胖是一个复杂的生理变化过程，单个基因或一部分基因会能起到真正的作用，没有大规模人群实验检测基因相互作用还很困难，而且当前的候选基因变化并不是人类肥胖的主要原因。
