1) shoaling properties
变浅性
1.
In this paper, a new form of second-order fully nonlinear Boussinesq wave equation, which is applied to deeper water, is established through changing dispersion terms of a set of extended ones, with linear dispersion and shoaling properties improved and without having its mathematical form changed.
通过改进二阶全非线性Boussinesq波浪方程中的色散项,得到了一组没有改变原方程的数学形式但适用于更大变化水深的新方程,其色散性能和变浅性能都比原方程有了很大改进,所适用的水深范围更大,能更好地描述从深水到近岸浅水处的波浪传播;并基于新方程建立了波浪数值模型,通过模拟波浪从浅水到深水的传播变形来验证新方程的有效性。
2) pellic vertisol
浅色变性土
3) shoaling characteristic
变浅作用性能
1.
Also by the comparison with the model derived by Schaffer and Madsen, the two parameters are obtained, which improve the linear shoaling characteristics, and the applicable water depth is increased by nearly one time.
利用该方法,从传统的Boussinesq方程出发,通过引用2个参数来改善方程的色散性,并通过与Schaffer和Madsen的模型对比给出这2个参数,使得波浪的变浅作用性能得以改善,同时方程的适用水深提高近1倍。
5) shoaling
[英][ʃəul] [美][ʃol]
变浅
1.
The linear dispersion is accurate to Padé(4,4)expansion of linear Stokes s dispersion,the shoaling is applicable to a relative water depth(wavenumber is multiplied by water depth) not being greater than 6 and nonlinearity is accurate to the relative water depth not being greater than 1.
在他人给出的方程的基础上,通过在其动量方程中引入含4个参数的公式,推导出了加强的适合复杂地形的水波方程,新方程的色散、变浅作用以及非线性均比原来适合复杂地形的方程有了改善:色散关系式与斯托克斯线性波的Padé(4,4)阶展开式一致;变浅作用在相对水深(波数乘水深)不大于6时与解析解符合较好;非线性在相对水深不大于1。
6) Shallow-buried plastic rheological rock mass
浅埋塑性流变岩体

外源性变应性肺泡炎
又称"变应性肺泡炎"、"职业性哮喘"、"过敏性肺炎"。吸入有机粉尘引起的一类肺部变应性疾病。有机粉尘包括植物性（如嗜热菌孢子、枯草杆菌等）和动物性（如动物蛋白、垂体素粉剂等），都可作为抗原性物质，通过吸入肺部引起致纤维性肺泡和间质的炎症病变。临床可表现有发热、畏寒、乏力、全射肌肉酸痛、刺激性干咳、胸部紧迫感；有时可出现类似支气管哮喘发作的症状。免疫学检查，90%的患者血清内有IgE。糖皮质激素对本病有较好的疗效。晚期可发展为弥漫性肺间质纤维化，甚至"蜂窝肺"。
