This study explores a novel WNbMoTaV high-entropy thin film(HETF)in amorphous structure via pulsed laser deposition *** formation of amorphous structure of this high-entropy alloy is ascribed to the high cooling rate during the deposition *** HETF shows a smooth surface with a height fl uctuation of less than 13 *** film has a high electrical resistivity of~320.6μΩ·cm and a low corrosion current density of 0.088μA/cm *** corrosion resistance of the HETF at ambient temperature is superior to the conventional AISI 316 L stainless *** high electrical resistivity and excellent corrosion resistance of the HETF are mainly attributed to its chemical disorder,cocktail effect and homogeneous amorphous *** experimental phenomenon not only provides a basis for the preparation of amorphous alloy films with low glass forming ability by pulsed laser deposition system,also promotes the potential application of WNbMoTaV HETF in the microelectronic components as resistivity sensors.

Effects of entropy and free radical in life system are elucidated. The results indicate that living organism can maintain normal activities only if a suitable free radicals inside living organism can be guaranteed. Excessive free radical should be eliminated to reduce entropy in living organism. Some ways provided to eliminate excessive free radical, reduce entropy and keep health.

The ground-state energy and its derivate of the acoustic polaron in free-standing slab are calculated by using the Huybrechts-like variational approach. The criteria for presence of the selftrapping transition of the acoustic polaron in free-standing slabs are determined qualitatively. The critical coupling constant for the discontinuous transition from a quasi-free state to a trapped state of the acoustic polaron in free-standing slabs tends to shift toward the weaker electronphonon coupling with the increasing cutoff wave-vector. Detailed numerical results confirm that the self-trapping transition of holes is expected to occur in the free-standing slabs of wide-bandgap semi-conductors.

The variational effective mass with respect to the e-p coupling constant for different values of cutoff wave vector is performed in quantum dot. The self-trapping transition of acoustic polaron in quantum dot is reconsidered by character of the effective mass curve varying with the e-p coupling. The holes are determined to be self-trapped in AlN quantum dot systems.

矿井地表水与深部水形成机制及控制因素分析

为了探讨地表水和深部的奥灰水、十_(下)灰水的变化特征,基于水化学角度选取了东滩煤矿3种共计28个水样(9个奥灰水样品,6个十_(下)灰水样品和13个地表水样品)进行对比分析。绘制了研究区水化学的Piper三线图解,分析了3种水样的水化学典型特征离子关联性,利用因子分析探讨了地下水水化学成分控制因素,再通过分析水岩作用机理比较了奥灰水、十_(下)灰水和地表水之间主控因素的强弱和水环境变化过程。分析结果表明:奥灰水存在碳酸盐溶解、硫酸盐溶解和硅酸盐风化现象;十_(下)灰水存在蒸发盐溶解、硅酸盐风化和脱硫酸作用,其中蒸发盐溶解占主导地位,且以静储量为主,容易疏干;地表水存在硫酸盐溶解、碳酸盐溶解和硅酸盐风化,发现地表水的硅酸盐风化比深部的奥灰水和十_(下)灰水更强。3种水样均存在一定的阳离子交替吸附作用和硅酸盐矿物的溶解作用,地表水和矿井深部水控制因素具有明显的差异性。研究结果对东滩煤矿采掘中的突水水源判别提供了重要依据。

为探究特厚煤层综放开采条件下底板变形破坏深度,以兖矿能源集团股份有限公司东滩煤矿1305工作面为背景,采用现场实测、数值模拟和理论计算等方法综合分析了该工作面采动煤层底板变形破坏深度。采用应变感应法和钻孔成像技术的现场实测结果表明:底板受采动矿压作用在水平和垂直方向上存在明显的显现特征,水平方向上超前测点50 m附近、底板浅部10 m深度位置开始受采动矿压影响,工作面推过一定距离之后底板变形破坏剧烈;底板不同深度水平方向上超前距和滞后距变化范围分别为96~115 m和48~52 m,工作面综放开采底板变形破坏深度为16~20 m,垂深20 m以下底板岩层以弹性变形为主。数值模拟的底板不同深度塑性区分布特征表明,随着距工作面底板距离越远,受采动矿压影响越小,塑性区范围越小,底板下20 m基本没发生破坏。理论计算结果确定了底板变形破坏深度为19.2 m。综合现场实测、数值模拟和理论计算结果,可知1305工作面综放开采底板变形破坏深度不超过20 m。研究结果可为矿井特厚煤层综放开采底板水害防治提供量化依据。
