Numerical simulations of nonlinear interaction of space charge waves in microwave and millimeter wave range in n-InN films have been carried out. A micro- and millimeter-waves frequency conversion using the negative differential conductivity phenomenon is carried out when the harmonics of the input signal are generated. An increment in the amplification is observed in n-InN films at essentially at high-frequencies f < 450 GHz, when compared with n-GaAs films f < 44 GHz. This work provides a way to achieve a frequency conversion and amplification of micro- and millimeter-waves.

Singularity-free superstar is proposed as a model for the collapse of large stars and for GRBs, and as an alternative to black hole and gravastar. Similar to a superconductor, a superstar contains extreme force fields that have non-zero momentum and non-zero wavelength to prevent the inactivation of force field at absolute zero and singularity (infinite interacting energy) at infinite density, respectively, based on the uncertainty principle. Emerging only at an extremely low temperature above absolute zero or an extremely high density below infinite density, extreme force fields are shortrange, and located in between a particle and its ordinary force fields (electromagnetic, weak, strong, and gravitational forces) to prevent the inactivation of force fields at absolute zero and singularity (infinite interacting energy) at infinite density in ordinary force fields. Extreme force fields are manifested as the bonds among electrons in a superconductor and among atoms in a Bose-Einstein condensate. When the stellar core of a large star reaches the critical extreme density during the stellar collapse, the stellar core is transformed into the super matter core with extreme force fields and ordinary force fields without singularity. A pre-superstar contains the super matter core, the ordinary matter region, and the thin phase boundary between the super matter core and the ordinary matter region. The stellar collapse increases the super matter core by converting the in falling ordinary energy and matter from the ordinary matter region into the super matter, and decreases the ordinary matter region. Eventually, the stellar breakup occurs to detach the ordinary matter region and the phase boundary from the super matter core, resulting in GRB to account for the observed high amount of gamma rays and the observed complex light curves in GRBs. Unlike black holes and gravastars that lose information, singularity-free superstars that keep all information exist.

In the proposed light-dark dual universe, the light universe is the observable universe with light and kinetic energy that fueled the Big Bang, and the dark universe without light and kinetic energy has been observed as dark energy since about 9 billion years after the Big Bang. The light-dark dual universe started from the zero-energy universe through the four-stage cyclic transformation. Emerging from the zero-energy universe, the four-stage transformation consists of the 11D (dimensional) positive-negative energy dual membrane universe, the 10D positive-negative energy dual string universe, the 10D positive-negative energy dual particle universe, and the 4D (light)-variable D (dark) positive-negative energy dual particle asymmetrical universe. The transformation can then be reversed back to the zero-energy universe through the reverse four-stage transformation. The light universe is an observable four-dimensional universe started with the inflation and the Big Bang, and the dark universe is a variable dimensional universe from 10D to 4D. The dark universe could be observed as dark energy only when the dark universe turned into a four-dimensional universe. The four-stage transformation explains the four force fields in our universe. The theoretical calculated percentages of dark energy, dark matter, and baryonic matter are 72.8. 22.7, and 4.53, respectively, in nearly complete agreement with observed 72.8, 22.7, and 4.56, respectively. According to the calculation, dark energy started in 4.47 billion years ago in agreement with the observed 4.71 ± 0.98 billion years ago. The zero-energy cyclic universe is based on the space-object structures.

研究眼内房水流动有助于认识眼睛疾病(如青光眼)的发生机理.该文利用计算流体力学计算了人眼睫状体分泌的房水由后房流经5μm和30μm虹膜-晶体间隙进入前房,再经小梁网排出这一过程,分析了平视、仰视、俯视不同体位以及不考虑浮力因素的房水流场.结果表明不同情况的房水压力场类似,5μm虹膜-晶体间隙时后房眼压比前房约高30 Pa,而30μm时前后房压力基本相同,小梁网压力下降明显.前后房压差驱动房水从后房流经虹膜间隙到前房,而角膜与虹膜温差引起的自然对流为前房房水的主要流动.前房自然对流引起的压差变化在mPa量级,温度较高房水汇集区域压力稍高.平视时主要为前房虹膜侧房水上升、角膜侧下降的自然对流循环;仰视时瞳孔区房水沿前房中心轴上浮,然后沿角膜向周边下沉,从虹膜周边部位到瞳孔,形成轴对称的对流模式;对于俯视,流动模式与仰视正好相反,前房中心轴上房水从角膜运动到瞳孔处;不考虑浮力作用时,房水的平均速度比自然对流时小1~2个数量级.

为了确保不同种易燃危险物体以及延伸管道结构的安全性,本文提出了由超声波导和微控制器建立的管道防火控制系统,并对其可行性进行分析。如今,用于监测泵站外部延伸管道部分的消防安全设备还十分稀少,这正是本研究主要解决的关键问题。文中对已有的设备结构进行详细分析与对比后,选定由柔性耐热线制成的超声波导为敏感元件,并使用物理现象驻波作为该监测器的工作原理。本文制定了技术规范,创建了电气结构和电气功能图,并在此基础上,为管道防火控制系统设计了电气原理图。此外,本文在开发该监测系统的过程中计算了各项技术设计指标,并针对元件基座的选择得出印刷电路板上的各元器件的特性。此处,本文选择了最优设计方案,并计算了所设计设备的总尺寸。由于微控制器在本文开发的系统中起着重要作用,本文为该监测器已有的两种操作模式(即监控模式与报警模式)写入算法,并基于该算法,使用C编程语言编写了微控制器的程序代码,已对程序进行检验且已成功编译。在已有信息的基础上,本文还对管道点火控制系统进行了仿真模拟。即使在个别模块的操作参数发生变化的情况下,系统也可以正确运行。与现有的系统相比,本文提出的监测系统在使用过程中将为安装和操作过程节省大量资金。最重要的是,本文系统将各类易燃物体的防火安全水平提高到一个新的高度。

It is proposed that the digital space structure consists of attachment space (denoted as 1) for rest mass and detachment space (denoted as 0) for kinetic energy. Attachment space attaches to object permanently with zero speed, and detachment space detaches from the object at the speed of light. The combination of attachment space and detachment space brings about the three structures: binary lattice space, miscible space, and binary partition space. Binary lattice space, (1 0)n, consists of repetitive units of alternative attachment space and detachment space. In miscible space, attachment space is miscible to detachment space without separation. Binary partition space, (1)n(0)n, consists of separated continuous phases of attachment space and detachment space. Binary lattice space, miscible space, and binary partition space constitute quantum mechanics, special relativity, and the extreme force fields, respectively. Through the detachment space, a higher dimensional particle in attachment space is sliced into infinitely surrounding a lower dimensional core attachment space, resulting in a particle surrounding by gauge field in the form of binary lattice space. The 10d particle can be sliced into 9d, 8d, 7d, 6d, 5d, and 4d particles equally by mass, corresponding to baryonic particle as 4d and dark matter as other 5 particles, so the ratio between baryonic matter and dark matter is 1 to 5, in agreement with the observed ratio. At extreme conditions, such as extremely low temperature, the gauge force field in the form of binary lattice space is transformed into the extreme force field in the form of binary partition space to explain extreme phenomena, such as superconductivity.

在激光加工过程中,保护气和载粉气对熔池氧含量有很重要的影响,为了减少在开放条件下激光加工过程中产生的氧化,需要研究保护气和载粉气工艺参数对激光加工过程中氧化行为的影响。以激光重熔45钢为例,通过测定熔池上方气氛以及重熔后基材表层的氧含量,对比研究了不同保护气流量、载粉气流量和离焦量对激光重熔过程中氧化行为的影响。结果表明:气流量较低时,气流卷吸周围空气,载粉气流量、保护气流量以及离焦量升高会加剧激光重熔时的氧化。当载粉气流量超过84 L/min时,大量氩气对周围空气进行了稀释,熔池上方气氛中的氧含量会有所降低。但是保护气流量过高会加剧熔池飞溅。降低熔池上方气氛中氧含量的气流量工艺参数为:保护气流量8.5 L/min,载粉气流量6.5 L/min。
