Low-frequency covibration experiments of four kinds of fluid-saturated feldspar sandstones which have different viscosity coefficients respectively were conducted so as to know how fluid viscosity coefficient influences attenuation, modulus and velocity dispersion in fluid-saturated sandstone.

为了探讨孔隙流体的黏滞系数对饱和砂岩的衰减、模量和速度色散的影响，本文进行了四种不同黏滞系数的饱和长石砂岩的低频共振实验，结果发现在0.01～10Hz频带范围内，无论是衰减温度话还是衰减频率谱，都显示出衰减随黏滞系数的增大成良好的线性增长关系，黏滞系数越大楼量越大；同时还具有明显的模量与速度色激，而且随着黏滞系数的增大，模量与速度色权有增强的趋势。

Indeed, the Grand Canal was constructed partly utilizing the pre-existing channels connecting these lowland swamps and lakes (3) Several rivers have produced deltaic forms on the western side of the lakes;(4) A series of artificial islands have been constructed upon the natural bars or barriers located in the lakes and wetlands, and are locally termed Duo, Dun or Wei (meaning artificial bars or crossways in Chinese).

钻孔B/M界线之下(4078 m～4530 m)的泛滥平原河湖相沉积物中局部地段富含铁锰鲕粒，其主要矿物组成为蛋白石、铁的氢氧化物(包括纤铁矿、水纤铁矿、针铁矿、水针铁矿，统称褐铁矿)、铁锰氧化物(包括硬锰矿和软锰矿，以硬锰矿为主)及极少量的细小碎屑矿物(钾长石、蚀变黑云母、含铁白云母、锆石、独居石、金红石和含钛磁铁矿)。

The results showed that:①the crystalline phases are mainly the cuspidine, wollastonite and gehlenite with nepheline, fluorite and olivine also found in some samples under the experimental conditions;②with the bacisity and CaF_2 content increased, crystalline proportion of mold flux rises .

熔融保护渣在MoSi2高温电阻炉内以2℃/min降温速率冷却至室温，制成薄片，采用岩相显微镜分析保护渣的结晶矿相·结果表明：在本实验条件下，结晶矿相主要有枪晶石，硅灰石，黄长石，个别渣样有霞石，萤石，橄榄石；增大保护渣碱度，能促进保护渣结晶；随着渣中CaF2，Na2O，K2O和Li2O质量分数的增大，保护渣结晶化率增大；随着渣中Al2O3，MgO，BaO和MnO质量分数的增大，保护渣结晶化率减小

The primary ores of the Laozuoshan gold deposit is a heavily disseminated and massive gold ores the main metallic mineral of which is pyrrhotite that account for approximately 11% occurring in migmatitic granite in disseminative and massive form and its gangue minerals take about 80% with quartz and feldspar as main minerals.

老柞山金矿原生矿石为稠密浸染状、致密块状金矿石，矿石中主要金属矿物为磁黄铁矿，约占11%，磁黄铁矿以浸染、致密块状分布于混合花岗岩中；脉石矿物约占80%，以石英、长石为主。

All protruding angles of equigranular melilites are 90°.

黄长石等粒状，无论形态多么复杂，边缘凸角均为90°左右。

The studied results show that feather-like hardystonite crystallizes in R2O-CaO-ZnO-Al2O3-SiO2, systems and the macrocrystalline of it will be gotten in the low concentrations of SiO2 and Al2O3, It is evident that the tendency towards the crystallizing of Hardystonite decreases with the equimolecular substitution of K2O by Na2O when the .

本文通过大量的配方实验和OM、XRD分析，系统研究了R2O－ CaO－ ZnO－ Al2O3－SiO2系统锌黄长石析晶与组成和热处理温度间的相互关系。

The study show that: the reservoir sandstone is mainly made of feldspathic sandstones.

研究表明，研究区长6油层组储层砂岩主要为长石砂岩。

Type of sandstone is mainly to sublitbarenite, feldspathic litharenite and lithoclastic feldspar are account for a large proportion.

砂岩类型主要为亚岩屑砂岩，长石质岩屑砂岩和岩屑质长石砂岩也占较大比例。

For example, glasses containing MgO where dolomite is cheaper than limestone, and low alumina glasses where feldspar or feldspathic sands are at a premium.

再举个例子，在白云石比石灰石廉价的地区出产的玻璃里会含MgO；在长石或长石质砂价格高涨的地区会出产低铝玻璃。

At present,these sandstones are at the late A period of the early diagenetic stage（Ro=0.8%,T=70℃-90℃）,and their diagentic fabrics are controlled by the acidic diagenetic environment, resulting in widespread dissolution of feldspathic grains and well developed quartz overgrowth.

砂岩目前处于早成岩阶段B期的晚期，Rt，为0.8％，温度在70℃～90℃，成岩组构特征受酸性成岩环境控制，因此长石类易溶颗粒普遍发生溶蚀作用，石英次生加大发育。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
