谈日语口语中语气助词的作用

日语中的语气助词在词性分类上排序在后，且在语法理论上对语气助词的讲解也往往被忽视，尤其在口语交流中更不为人所注意，本文仅就口语中语气助词的作用作以探讨。

粘土调剖剂对中低渗透层的污染及其解除方法

用动滤失仪评价了粘土调剖剂对中低渗透层的污染情况。研究表明，注入压力越高。中低渗透层的污染越严重；地层的非均质程度越高，中低渗透层的污染越小．解除污染的方法有返排法和土酸酸化法。试验证明，返排法不能从根本上解除污染，常规土酸酸化方法的效果较好。     

Viscosity of some clay-based coating colors at high shear rates

The shear viscosity of clay-based coating colors containing latex and carboxymethyl cellulose (CMC) has been measured over a relatively large shearrate region. In the shear-rate range of 50–1500 s^–1 the measurements were performed using a rotational viscometer and, at higher shear rates extending into the region 10⁵ – 10⁶ s^–1, a high pressure capillary viscometer was employed. The viscosity of the clay colors increased with increasing CMC-concentration, but the influence of the CMC-content was less pronounced at higher shear rates. The apparent shear-thinning behavior of the investigated colors could, in part, be attributed to the shear-thinning of the corresponding polymer (CMC) solution constituting the liquid phase of the color, but the influence of another factor was also indicated. At low shear rates, the interaction between the color components can produce relatively high viscosity levels, but in the high shear rate region these interactions appear to be less important for the viscosity level. It is also of interest to note that the viscosity dependence on the solids content in the high shear-rate region could be described with reasonable accuracy using an empirical equation neglecting interactions between the color components.     

The effect of dissolved polymers on the rheological properties of coating colours

Coating colours used for the coating of paper and board consist mainly of a mineral pigment, which is very often clay, a synthetic binder such as a styrenebutadiene latex, dispersion agents and water retention aids. The latter are often water soluble polymers. These polymers have a very strong influence on the rheological properties of the coating colours, both on the strain rate dependence of the apparent viscosity and on the viscoelasticity. The effects of two different grades of carboxymethylcellulose (CMC) and one grade of hydroxyethylcellulose (HEC), on the rheological properties at room temperature of a clay-based coating colour at pH 8, have been investigated. It is concluded that the high values of the dynamic modulus of the colours are due to interactions between the cellulose derivatives and the solid particles, i.e. mainly the clay particles. For HEC this interaction is associated with adsorption of the polymeric molecules on the clay particles. In the case of CMC, the adsorption is strongly retarded by the presence of the dispersant (a polyacrylate salt). It is suggested that the marked elasticity of the CMC-containing colour in addition to a possible polymer adsorption may be due to charge interactions and/or depletion flocculation. The effect of CMC and HEC on the water-retention properties of the colour is also discussed.     

认知无线电Mesh网络路由选择的动态分层图模型

为了能够对认知无线电网络路由协议进行有效的分析,特别针对其动态频谱特性,需要一个动态的路由模型。提出了动态分层图模型,通过子节点的划分,用子节点的状态反映信道的可用性,并将每个子节点的状态看成一个随时间变化的随机变量,通过子节点状态的动态性,建立认知无线电网络的拓扑和连通性动态模型,并对动态分层图的性能进行了仿真分析。仿真结果表明,动态分层图模型在适应频谱的动态变化和描述认知网络的拓扑结构方面,表现出比静态分层图模型更加优异的性能,能够有效地适应认知无线电网络的动态频谱特性。
