Transportable refillable brazed steel cylinders for liquefied petroleum gas - design and construction ; german version en 12807 : 2001 液化石油气用便携式可再充填的钎焊钢瓶.设计和制造
The data of fluid inclusion analysis showed that the filling of minerals mainly happened during the burial period 各种自生矿物充填的不均匀性揭示了岩石与孔隙水之间相互作用的复杂性,以及岩溶水在不同时期是变化的。
The riding position of signal wire was not always in the vertex of the impression from the conclusions of production , but in the position in which aluminous liquid tilted at last 由生产实践总结出信号线的安放位置不一定在型腔最高点,而应在金属液最后充填的位置。
Based on cad software such as ug and solidworks and hzcae system , experimental data design was researched , which includes three - dimension solid model and some figures of temperature field , flowing field and simulation filling in shape theory and mould dismount - installation experiments 利用ug和solidworks等cad软件和hzcae系统完成实验数据的设计。其中包括成型理论实验和模具拆装实验中应用的三维实体模型,成型理论实验涉及到的温度场、流动场、和模拟充填的图片。
We find that the petrology characteristic of all the samples have no characteristic of meteoric water such as geopetal structure , infiltrative sand , ( uniform cement and gravitational cement on base of the research of the dolomite in the regions . on the dot diagram of combination of mgco3 ( mol % ) and sr , the dot are all close to the line of seawater whether they are microlite - crystalline penecontemporaneous dolostone or diagenetic dolostone of various crystals . the 87sr / 86sr value of dolostone or matrix is less than the one of sparry calcite in cave or vein , and close to the value of seawater 通过本区白云岩的研究发现:已有的白云岩样品的岩石学特征没有显示出如示底构造、渗滤沙、新月型胶结物和重力胶结物等大气淡水作用的特征;在白云石mgco _ 3mol百分数和白云石sr含量的投点图中,无论是准同生成因的泥?微晶白云岩,还是粉?细晶(或中晶,或细晶以上的不等晶)的成岩白云岩,均投在海水线的附近;白云岩(或基质)的~ ( 87 ) sr / ~ ( 86 ) sr比值显著低于与孔洞或脉中充填的亮晶方解石,且与海水值十分接近, ~ ( 13 ) c和~ ( 18 ) o值显著高于孔洞或脉中充填的亮晶方解石,也偏向于海水值; mn含量则显著低于孔洞或脉中充填的亮晶方解石。
The effect of overburden separation dynamic development under key stratum on grouting for bed separation space was analyzed , in order to deal with the problem that the current bed separation growing technology can not prevent the key stratum from breakage , put forward the isolated section - grouting technology for overburden bed separation space , integrated the virtue of growing for bed separation space and partial extraction , the bed separation grouting bodies , key stratum and isolated section pillars were made to constitute the load - carrying body all together , and to reach the purpose of reducing subsidence effectively , increase the coal seam extraction ratio , and accelerate the development of isolated section - growing technology for overburden bed separation space 摘要分析了关键层下离层动态发育对离层充填的影响,针对目前离层区充填工艺不能阻止覆岩关键层初次破断的问题,提出了“覆岩离层分区隔离注浆充填”技术,它综合离层充填与条带开采技术的优点,通过离层区充填置换或减小分区隔离煤柱宽度,使“离层区充填体关键层分区隔离煤柱”形成共同承载体,从而达到有效减缓地面沉降的目的,提高了煤层采出率,促进了覆岩离层充填减沉技术的发展。
At present , the infrared transmission spectroscopy is the best technique for determining whether jadeite is polymer - impregnated or not , and the infrared reflectance spectroscopy is a nondestructive and rapid determination method that provides mainly the fundamental frequency vibration spectra data of minerals and shows new application potentials in gemological research , especially in the identification of gem species 摘要红外透过光谱技术是当前鉴别翡翠是否有聚合物充填的最好方法,而红外反射光谱技术是一种快速、无损伤的测试方法,主要提供矿物的基频振动光谱信息,在宝石学研究方面特别是鉴定宝石种属方面显示出新的应用可能性。
