冲击波

This result provides experiment reference to attenuator design.

这为制定起始冲击波抑制方案提供了实验依据。

The average propagation velocity of the laser-induced shock wave in aluminum is 6.38×10 3m/s.

激光引发的冲击波峰值压力在铝中的衰减规律是指数型的。

The average propagation velocity of the laser-induced shock wave in stainless steel was 5.72×10^3m/s.

激光冲击波在不锈钢材料中的平均传播速度为5.72×10^3m/s，与声波纵波的传播速度一致。

Treatment method uses 1 · Germany produces · of 0/9 of · of Wolf F 8 lens of 0 rigid ureter kidney, homebred APL baric and ballistic stone crusher and homebred microcomputer charge pump.

现将护理心得报告如下。1资料和方法1·1临床资料本组102例，其中男72例，女30例，年龄19~65岁(平均42岁)；左侧输尿管55例，右侧输尿管42例，双侧5例；其中1例行体外冲击波碎石术治疗多次结石未粉碎，2例为ESWL治疗后引起"石街"。1·2治疗方法采用德国产Wolf F 8·0/9·0硬性输尿管肾镜，国产APL型气压弹道碎石机以及国产微电脑灌注泵。

This method is used when the stone is large and not able to be removed by extracorporeal shock wave treatment.

这种方法时所用的石头是大和无法被删除体外冲击波治疗。

BACKGROUND: It can be confirmed by the clinical trial that chronic plantar fasciitis can be treated by extracorporeal shock wave. There are some different explains for the mechanism of action.

学术背景：已经证实应用体外冲击波治疗慢性足底筋膜炎的疗效是确定的，关于其作用机制有不同的解释，尚未完全明确。

However, the DBT temperature of notched specimen by shock waves treatment in impact toughness test is increased, which is believed to be caused by the shock induced decreasing of crack forming energy in the material.

文章还发现冲击波引起材料在脆性转变温度下缺口试样的裂纹形成功的下降是造成以缺口冲击韧性表征的脆性转变温度升高的主要原因。

The theoretical minimum movement velocity for the sheet to be punched by laser shock wave s was deduced.

为了验证激光冲击波冲孔工艺的可行性，采用Nd玻璃高功率脉冲激光器在0.4mm厚锻铝合金板料上进行冲孔试验。

Experimental measurements were also presented with a well-designed optical fiber sensor based on detection beam deflection.

采用自行研制的光偏转测试系统对该冲击波进行了多点测量。

The results show that overpressure bench mark is well suited for describing anomaly distribution, and momentum bench mark can provide better measure for shockwave damage. Along with increasing of the branch deflexion angle, the primary tunnel momentum increases and the branch tunnel momentum decreases, and plane shockwave recover distance also increase but will not exceed six times equivalent diameter.

研究结果表明：超压准则适用于描述分布的不均性，而冲量准则能更好地衡量分叉巷道中冲击波的破坏作用；分叉角度的影响较大，随着分叉偏转角的增大，主巷道内冲量将增大而分巷道内冲量将减小，恢复"平面波"的距离也增大，但不超过6倍巷道等效直径。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
