Taking the lindemann model as a sample system in which there exist chemical reactions, diffusion and heat conduction, we found the theoretical framework of linear stability analysis for a unidimensional nonhomogeneous two-variable system with one end subject to Dirichlet conditions, while the other end no-flux conditions. Furthermore, the conditions for the emergence of temperature waves are found out by the linear stability analysis and verified by a diagram for successive steps of evolution of spatial profile of temperature during a period that is plotted by numerical simulations on a computer. Without doubt, these results are in favor of the heat balance in chemical reactor designs.

PENILE fracture is a critical urological emergency, which is caused by the rupture of the tunica albuginea of the corpus cavernosum following blunt trauma to the erect penis. Traumatic injuries of the penis often occur in the erected state.1 Due to the possible embarrassment, this condition has been under- reported. Typically, the patient reports a snap or cracking sound accompanied by sharp pain and rapid penile detu- mescence, followed by immediate development of swelling and angulation.2 The common causes include direct injuries, forceful masturbation, or vigorous sexual intercourse.3 Most injuries to the penis need immediate surgical treatment. Here we report a case of penile fracture caused by traumatic injury.

为了解决二重管旋喷工法成桩直径的预测问题,通过对二重管法成桩过程的理论分析,建立了可以考虑压缩空气影响的二重管法成桩直径的计算方法,并给出了相应的详细计算步骤。二重管法施工期间,压缩空气包裹高压水泥浆射流可以有效降低射流速度沿喷射距离的衰减速率,增强高压射流对土体的切削效应,使得高压旋喷桩的成桩直径明显增加,提高旋喷工法对软土地基的加固效果。所提出的实用计算方法可以有效考虑土性参数、旋喷参数以及压缩空气的影响。以旋喷施工时的空气喷射压力为主要控制参数,通过回归分析提出了可以表达压缩空气对成桩直径增大效应的定量计算公式。针对二重管法施工中压缩空气的常用压力范围0.5～1.5 MPa,得到了压缩空气包裹高压射流对旋喷桩成桩直径的增大比例,为27%～81%,这与工程实践经验非常接近(一般压缩空气可以提升桩径的范围为30%～90%)。以温州深厚软土地区的二重管法工程实例为依托,根据旋喷施工参数与土性参数,采用所提出的计算方法与成桩直径的现场实测结果进行了对比分析。分析结果表明:对于2根试桩C1和C2(实测直径分别为1.08,1.12 m),应用所提出计算方法产生的相对误差分别为5.6%和6.3%(计算直径分别为1.02,1.05 m),由此可见所提方法可以满足工程设计与施工的要求。

分析了旧水泥混凝土路面采用不同沥青罩面工艺时,路面体系温度场从沥青层摊铺时刻的变化规律;并建立三维有限元模型,计算了不同碾压阶段水泥板内应力水平和翘曲变形状况;采用ProVAL软件计算了水泥混凝土板翘曲对沥青层平整度的影响。结果表明:直接在旧水泥路面表面加铺薄沥青罩面会使混凝土板上表面温度最高达80℃以上,在板内产生非常大的平均温升和温度梯度;旧水泥混凝土路面板在四边自由情况下由热翘曲产生的变形对沥青层的IRI影响非常明显;在旧水泥路面与沥青罩面间设置热阻隔离层,或者对罩面层采用多层多次施工工艺,能够有效降低旧水泥混凝土路面板热翘曲对沥青层平整度的不利影响。

以大同矿区双系煤层开采为研究背景,基于高精度微地震监测技术,研究石炭系特厚煤层8104综放工作面开采过程中上部侏罗系煤层群复杂采空区影响下微震事件时空演化特征,得到双系煤层影响下覆岩运动与矿压显现的关系。结果表明:8104工作面接近和进入上部侏罗系煤层采空区对应区域,8104工作面覆岩运动加剧,侏罗系煤层的开采是工作面覆岩运动加剧的主要原因;侏罗系煤柱重叠区域微震事件密集分布,在工作面的开采扰动和重叠煤柱应力传递的共同作用下,微震总能量和能量大于10~5J的震动次数均处于较高数值,覆岩运动更加剧烈。临近采空区对8104工作面的强烈覆岩运动起到了关键作用,在临近采空区和侏罗系覆岩共同作用下,工作面超前微震事件集中,矿压显现剧烈。工作面开采扰动、临近采空区覆岩运动和侏罗系重叠煤柱的耦合作用,是石炭系综放工作面矿压显现剧烈的根本原因。
