Consider the dependencies between the coefficients and their parents, a non-Gaussian bivariate distribution is given, and corresponding nonlinear threshold function is derived from the model using Bayesian estimation theory. According to non-subsampled Contourlet transform and bivariate threshold function, a novel Non-Subsampled Contourlet Transform based on Bivariate threshold function for image denoising is proposed. This scheme achieves enhanced estimation results for images that are corrupted with additive Gaussian noise over a wide range of noise variance.

The results of lattice beam internal force calculated method based on double parameter groundsill model are more approach the experiment measured values because of consideration of the pass of shearing force in soil, and its calculated workloads are similar with the method of winkler elastic foundation. Besides, the thesis also discusses the moment of torque affected results on node stress situation and the correction of stress value at the bottom of cross node of lattice beam. Due to the repeat calculation of node area during internal force calculation, the stress value of the bottom of beam is lower, this may lead the calculated value unsafe, but the corrected stress value will more approach to practical situation.
对格构梁的内力计算提出基于双参数地基模型的格构梁内力计算方法，其计算结果表明，双参数地基模型上的格构梁内力由于考虑土中剪力的传递更加接近于试验实测值，其计算工作量与winkler弹性地基梁法相当，此外，文中还探讨了扭矩作用对格构梁节点受力情况的影响结果以及格构梁交叉节点底部的应力值的修正，由于内力计算过程中节点处的面积被重复计算，使得梁底应力偏小，可能导致计算结果的偏于不安全，修正后的应力值更接近于实际情况。

Two-component waterborne polyurethane paint composed of acrylic dispersion and hydrophilically-modified polyisocyanate has fast dry time, good adhesion, flexibility, impact resistance, but poor water and chemical-resistance. The dry time becomes shorter with the increase of glass transition temperature and the decrease of acid value; the gloss of the film decreases with the increases of hydroxyl value, acid value and Tg of emulsion polymer; higher Tg polymer leads to harder film.
将制得的丙烯酸分散体与亲水改性多异氰酸酯组分配制水性双组分聚氨酯涂料，发现漆膜表干和实干比较快，干燥时间随玻璃化温度升高而缩短，随酸值的增加而增加；附着力、柔韧性和冲击强度比较好；光泽随分散体羟值、酸值的增加和玻璃化温度升高而降低；硬度随玻璃化温度升高而升高；较高的酸值使涂料的耐化学品性和耐水性较差，羟值在100mgKOH/g时较好，而酸值应尽可能低。
