| | Based on the analyzing the curves of p beach sand model test by Kolmer (1973) and the curves of a natural wave-buiit ripple sand in addition, and based on synthetically analyzing many double saltation curves of the environments of beach, tidal current and river regimes, the results are obtained in this study as follows:1.The definition of "swash-backwash separation" about the double saltation curve by Visher(1969) is out of accordance with the substance.2.The composite curve of the test by Kolmer (1973) exi... | | 双跃曲线历来被认为是海滩、双向流的沉积环境标志.本文详细分析实验海滩砂、天然浪成Ripple砂及综合国内外海滩、潮流和河流体系双跃曲线资料分析,指出维谢尔关于双跃式给出“冲流——回流分界点”的解释不符实质,修正科尔默双跃试验曲线的关系;提出了凹双跃和凸双跃的形成主要是底床剪切差异和水流剪切差异所决定,并非海滩、双向流环境的特有标志;说明粒度概率图对沉积环境不是直接反映,而对搬运介质水动力条件是直接反映,所以是研究环境水动力条件的手段之一;并根据合成曲线特定形式和概率坐标的关系,提出揭示曲线结构的“组合型”分析方法. | | 文摘来源 | | The liquid medium quick-freze technolgy for vegefables is to put the vacuum packed vegetables in liquid-tight bags on quick-freze basket frames which are then immersed in unfrozen liquid at low temperature of-22℃ to -25℃ for quick freezing, the freezing speed by this method is 50% higher the flow-bed method extensively practiced nowadays. Power consumption and cost of equipment are notably reduced .The quality of the quick-frozen vegetables is nearly the same as fresh ones. | | 液态介质速冻蔬菜工艺是将蔬菜真空包装后,装入速冻筐架的隔液袋中,速冻筐架浸入-22℃~-25℃低温不冻液体中进行速冻的工艺方法。此法冻结速度比目前广泛使用的流化床高50%左右,能耗和设备成本都有显著降低,速冻的蔬菜品质几乎与鲜菜没有差别。 | | 文摘来源 | | Zhougongshan structure is located in the southeast to the Yaan City,Sichuan Province,belonging to a fault-horst anticline. raied by two faults.Well Zhou-1 is located at the top of the structure. and a high commercial gas flow bed been obtained from the Permian basalt in this well,opening up a new domain for oil and po exploration in Sichuan. In the light of the CR vs Rt cronplot,the eruptive rock and the orther rocks formed ftom its wtalhering residues can be discriminated .and the profile may b... | | EvaluatingthePermianBasaltReservoirofWeelZhou-1¥NiuShan-zheng;PangJia-li(NorthwestSichuanMiningDistrictofSichuanPetroleumAdmi... | | 文摘来源 | |   | | << 更多相关文摘 |
