The present paper deals in detail with the origin, dynamics, geochemistry and physicochemistry of the ore-forming fluids, in combination with the origin of ore-forming matter, gold behaviour in the ore-forming fluids, equilibrium and unstability-precipitation in the course of migration on the basis of mineral composition and mineralization, alteration and ore-controlling factors of the representative gold deposits hosted in the Ailao Mountains ophiolitic melange belt, Yunnan.

笔者通过哀牢山蛇绿混杂岩带典型金矿床的物质组成、成矿规律、蚀变及控矿作用的研究，对哀牢山金矿带的成矿流体来源，成矿流体动力学、地球化学及物理化学性质进行了详细地讨论；对金矿的成矿物质来源，金在成矿流体中的存在形式，迁移过程中平衡、失稳-沉淀等进行了详细地分析和探讨。

The new findings suggest that overconsumption of highly palatable foods maintains bingeing by enhancing opioids in the brain, and that increased opioids could be a factor involved in binge eating disorders.

这项新的发现表明，过量食用可口的食物由于强化了大脑内阿片类物质从而导致了大吃大喝。而且增加的这类阿片类物质可能是暴食这类饮食疾病的一个因素。

Essence of oxido-reduction reaction is studied by the theory of Yuanji Diagram , the law of oxidability or reductibility of a matter is analysised, and the standard of deciding the weakness and strong-ness of oxidability or reductibility is given

用元极图理论研究氧化还原反应的实质，分析了物质的氧化性或还原性规律，提出了判断物质的氧化性或还原性强弱的标准。

At present,with the increasing studies on neuropeptide,many of them have shown that substance Pand vasoactive intestinal peptideare closely related to the occurrence of nasal polyps and colorectal polyps which are similar to the occurrence and pathology of vocal cord polyps.This article will discuss these aspects in order to investigate the relationship between SP,VIP and vocal cord polyps.

目前，随着人们对小分子神经肽研究的增多，P物质及血管活性肠肽和鼻息肉、直肠息肉等的发生之间的密切相关性已受到许多学者的证明和肯定，而声带息肉的发生、病理与鼻息肉及直肠息肉有相似之处，现拟从以上方面进行论述，以探讨P物质及血管活性肠肽与声带息肉发生的相关性。

The constituent of anti-virus activity was isolated from Parthenium hysterophorus by bioassay. The compound was identified as parthenolide through MS and NMR technique.

摘 要：采用活性跟踪法从银胶菊中分离获得抗病毒活性物质，经质谱和核磁共振分析，确定该物质成分为小白菊内酯。

Since the relative antioxidant capacity of all the phenolic compounds was much higher than trolox in both assays, it is a good indication that phenolic compounds possess high antioxidation capacity against peroxy radicals.

由於酚类物质之相对抗氧化力均远高於trolox，表示酚类物质对过氧自由基具有很好的抗氧化效果。

Among the 5 cultivars detected, Meiguihong contained the highest content of all 7 substances in three fruit parts, while for Naiyou and Manaizi cultivars the lowest. The peroxyl radical scavenging capacity method, with some modification, was used to evaluate the antioxidant capacity of grape extract.

结果表明，玫瑰红葡萄果皮、果肉和种子中7种生物活性物质组分的含量均高于其它品种，而奶油和马奶子果实中7种生物活性物质组分的含量较低或未检出。

In the scorch stage, average yield of withered grass of second and third year growth prematurity type of Phleum pratense L. is 10672.5 kg/hm2, by cradling one time per year, average yield of wind hay grass is 7575 kg/hm2, the plant average height of selective colony is 160.0cm, the plant height of colony is rather equality. In the course of general nutrition composition analysis, discover that nutrition value of late-maturity type is higher than nutrition value ofprematurity type, coarse fibre and coarse protein and coarse fat of late-maturity type are 10.7%, 3.58%, 24.82% respectively, coarse fibre and coarse protein and coarse fat of prematurity type are 9.84%, 2.61%, 27.59% respectively, dry matter content of prematurity type is 92.63%, dry matter content of late-maturity type is 92.22%.

在枯黄期，第二、第三年生的早熟类猫尾草一年收割一次，枯草平均产量为10672.5 kg/hm~2，风干草平均产量为7575 kg/hm~2，选育出的群体平均高度为160.0cm，群体内植株株高较均一；在常规营养成分的分析中发现晚熟类的营养价值稍高于早熟类，晚熟类的粗蛋白是10.7％，粗脂肪是3.58％，粗纤维是24.82％，早熟类的粗蛋白是9.84％，粗脂肪是2.61％，粗纤维是27.59％，早熟类干物质含量92.63％，晚熟类干物质含量92.22％。

At the same time, with the help of photoelastic techniques, we can build different experiments to simulate and help explain important granular systems in the nature, such as earthquake faults.

同时，借助光弹性材料，我们还可以构建一些模拟自然界中颗粒物质系统的实验，对颗粒物质的实际应用也有所裨益。

Visual carbon stars whose mid-infrared spectra are mainly dominated by photospheric continuum and show large excesses at 60um, represent a transition phase which follows an interruption of mass loss from the oxygen-rich phase and begins a new phase of the mass loss of carbon-rich material. Excesses at 60um in these stars are the emission from the residual of oxygen-rich material.

光学碳星的中红外能量主要来自光球，在60μm处存在超量发射，人们认为其演化阶段处在抛射富氧物质终止和新的富碳拱星壳层形成之间，其60μm超量发射就是富氧物质的残余效应。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
