区域应力场是构造运动的驱动力，是地壳应力研究中的重要内容，现今构造应力与地质资源的储存、开采及基础建设工程的设计实施具有密切联系。文章对锦州南部地区9个钻孔进行了翔实的现场水压致裂原地应力测试，并依据强度与应力指标，对应力状态和岩爆风险分别进行了评价与预测。结果表明，测区最大和最小水平主应力量值分别为3.92～17.33 MPa和3.00～8.93 MPa，垂直应力值为0.80～4.58 MPa，最大水平主应力方向在N33°～88°E之间，优势方位为N72°E；地应力评价结果显示为低～很低应力状态，工程区地下厂房附近无岩爆风险。

为研究球体垂直入水空泡的演化过程,基于N-S方程、VOF多相流模型及动网格技术,对球体的垂直入水过程开展了数值仿真模拟并进行分析。球体入水初期受到较强的冲击载荷并产生喷溅,球体入水后会产生和大气相连的入水空泡,空泡形成之后,依次经历发展、闭合以及溃灭等演化阶段,空泡受到的周围流体压力是空泡发生深度闭合的主要原因,空泡在闭合后会产生上下两股高速射流。结果表明:数值计算得到的球体垂直入水空泡形态和试验结果吻合良好,验证了仿真的准确性。

Tibetan singing bowls emit low-frequency sounds and produce perceptible harmonic tones and vibrations through manual tapping. The sounds the singing bowls produce have been shown to enhance relaxation and reduce anxiety. However, the underlying mechanism remains unclear. In this study, we used chronic restraint stress or sleep deprivation to establish mouse models of anxiety that exhibit anxiety-like behaviors. We then supplied treatment with singing bowls in a bottomless cage placed on the top of a cushion. We found that unlike in humans, the combination of harmonic tones and vibrations did not improve anxietylike behaviors in mice, while individual vibration components did. Additionally, the vibration of singing bowls increased the level of N-methyl-D-aspartate receptor 1 in the somatosensory cortex and prefrontal cortex of the mice, decreased the level of γ-aminobutyric acid A(GABA) receptor α 1 subtype, reduced the level of CaMKII in the prefrontal cortex, and increased the number of GABAergic interneurons. At the same time, electrophysiological tests showed that the vibration of singing bowls significantly reduced the abnormal low-frequency gamma oscillation peak frequency in the medial prefrontal cortex caused by stress restraint pressure and sleep deprivation. Results from this study indicate that the vibration of singing bowls can alleviate anxiety-like behaviors by reducing abnormal molecular and electrophysiological events in somatosensory and medial prefrontal cortex.
