滞泥

According to the characters of organic maceral, organic type, biomarker,it can be divided to five types of sedimentary facies: unrest restricted sea graptolite facies, alluvial restricted sea, carbonate mesa algal deposit facies, mud mesa algal deposit facies and deep water shelf algal deposit facies.

根据烃源岩有机显微组分、有机质类型、生物标志物及成烃能力等特征划分出五类沉积有机相，即动荡局限海笔石相、滞流局限海笔石相、碳酸盐台地藻积相、泥质台地藻积相和深水陆棚藻积相。

After mud-sediment changed into stone,the water flowing in pores of middle layer of mudstone has to overcome the starting resistance resulted from the water film forming in pores.Water is easily preserved in the pores and forms the undercompaction of the mudstone layer.

当泥质沉积物成岩以后，地层中部的孔隙水必须克服微孔隙对其产生的启动阻力才能向外排出；否则，地层水就被滞流在岩层孔隙中并造成泥岩的欠压实。

In the middle later period of diagenesis, the starting resistance increases, the fluid is not able to flow, the viscous resistance is equal to zero, the ultra-pressure value is equal to starting resistance.

在成岩作用的早期阶段，泥质岩层启动阻力较小，流体可以流动，流体超压由粘滞阻力和启动阻力两部分组成，当成岩作用进入到中－晚期以后，泥质岩层启动阻力增大，流体不能流动，粘滞阻力近似等于零，超压值等于启动阻力值。

The purpose of this study is discussing the shear stress and strain rate relation under different silt allocated proportion and different water content, and the viscosity coefficient and yield shear stress are estimated.

本研究旨在探讨模型材料在不同的泥砂配比及不同的含水量下剪应力和应变率的关系，并推估其黏滞系数和降伏剪应力。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
