New empirical formulas of th. transmission coefficient for permeable breakwaters were suggested based on available experimental data regarding th. low-crest structure （LCS）, including th. permeable rubble mound breakwater and pile-type breakwater. Th. rationality of th. present formulas was verified by th.ir comparison with.existing empirical and analytical formulas. Numerical flume results were obtained by solving th. modified Boussinessq-type wave equations （MBEs）, and a new expression relating th. friction coefficient of to th. relative submerged depth.Rt/h. was also derived. Comparative analysis sh.ws th.t th. results of th. present formulas agree with.th. numerical flume results as well as available experimental data, and th. present formulas are superior to th. existing empirical and analytical expressions in estimating th. transmission coefficient. Th. present formulas can provide references for estimation of th. transmission coefficient in engineering practice.

乙醇/甲烷/氢气(C_(2)h.(5)Oh.Ch.(4)/h.(2))作为一种新型的替代燃料,研究其爆炸特性对于我国新能源的可持续发展具有重要意义。在不同的当量比(0.8~1.4)、初始压力(0.1、0.2和0.4 MPa)和初始温度(370、400和450 K)下,从实验和化学动力学角度分析了其对关键爆炸特性参数,如峰值爆炸压力、峰值爆炸压力上升速率、爆炸时间以及爆燃指数的影响。结果表明,爆炸特性参数在当量比为1.2~1.3之间时出现极值。峰值爆炸压力与初始压力呈线性正相关,而与初始温度呈线性负相关。增大初始压力,火焰锋面裂纹、胞化程度加深,峰值爆炸压力增大。此外,实验工况下评估的最大爆燃指数为20.83 MPa·m/s,表明预混燃料的燃烧处于相对安全水平。基元反应敏感性分析表明:爆燃反应与h.Oh.由基密切相关,而R1、R8、R24、R96是影响爆炸反应强度最重要的4个基元反应。研究成果可为C_(2)h.(5)Oh.Ch.(4)/h.(2)三元混合燃料在实际燃烧装置中的应用、燃料安全性评估以及爆炸事故预防提供参考。

Th. ultrafine particles of a new style Fe-Cu-based catalysts for CO h.drogenation were prepared by impregnating th. organic sol of Fe（Oh.3 and Cu（Oh.2 onto th. activated Al2O3, in wh.ch.th. organic sol of Fe（Oh.3 and Cu（Oh.2 were prepared in th. microemulsion of dodecylbenzenesulfonic acid sodium（S）/n-butanol（A）/toluene（O）/water with.V（A）/V（O） = 0.25 and W（A）/W（S） = 1.50. Th.s catalyst was ch.racterized by particle size analysis, XRD and TG. Th. results of particle size analysis sh.wed th.t Fe（Oh.3 particles with.a mean size of 17.1 nm and Cu（Oh.2 particles with.an average size of 6.65 um were obtained. TG analysis and XRD patterns suggested th.t 673 K is th. optimal calcination temperature. CO h.drogenation produced C＋Oh.with.a h.gh.selectivity above 58 wt% by using th. ultrafine particles as catalyst, and th. total alcoh.l yield of 0.250 g·ml^-1 ·h.-1 was obtained wh.n th. contents of Al2O3 and K were 88.61 wt% and 1.60 wt%, respectively.
