The explosive performances of DAAT were calculated theoretically by VLW equationofstate (EOS) and the results showed that several explosive formulations based on DAAT have highenergy and insensitive performance.


Experiments on both synthesis and real datasets show that the new algorithm not only achieves a significant gain of runtime and quality to find subspace clusters, but also is insensitive to input parameters.


It is found that the calculated results also agree with M?ller's results and that the MM model is insensitive to the microscopic singleparticle potential.


It grew well in 95% alcohol disinfectant and was insensitive to 84 disinfectant fluids containing chlorine (1000 mg/L) and such disinfectants as ozone.


The bacteria contained a 2.5 kb plasmid and were sensitive to 13 drugs and insensitive to 7 drugs of the 20 drugs tested.

 Some types of glass made thermal conductivity cells for gas analysis were prepared by author, which were constructed with tungsten wire 0.013m. m. in diameter, as a hot wire. Some of their properties had been tested with the gaseous mixtures of hydrogennitrogen and of aircarbon dioxide. The prepared thermal conductivity cells may be used with a higher sensitivity, and insensitive to the variation in the rate of gasflow; and with a rapid response to the variation in the composition of gaseous sample during... Some types of glass made thermal conductivity cells for gas analysis were prepared by author, which were constructed with tungsten wire 0.013m. m. in diameter, as a hot wire. Some of their properties had been tested with the gaseous mixtures of hydrogennitrogen and of aircarbon dioxide. The prepared thermal conductivity cells may be used with a higher sensitivity, and insensitive to the variation in the rate of gasflow; and with a rapid response to the variation in the composition of gaseous sample during the continuous analysis. The apparatus can be used suitably as a detector in gas chromatography.  作者用直徑爲0.013mm鎢絲爲熱絲、試制了幾種玻璃制氧體分析用導熱池,並用■—■混合物和空氣—二氧化碳混合物試驗其性能。所製得的導熱池具有較高的靈敏度,對氣體流速改變不靈敏。在連續分析中,對氣體組成改變的反應較快,可適於在氣相色層中用作测定器。  In this paper, by means of phase space and point transformation method, the second order system with dead zone and hysteresis loop has been studied. Various possible motions of system are described by phase trajectory and topological construction of phase space is demonstrated. The parameter plane is divided into stable region and selfoscillating region. A precise method for calculating amplitude and period of selfoscillation is obtained. Finally, an example of calculating amplitude and period is presented.... In this paper, by means of phase space and point transformation method, the second order system with dead zone and hysteresis loop has been studied. Various possible motions of system are described by phase trajectory and topological construction of phase space is demonstrated. The parameter plane is divided into stable region and selfoscillating region. A precise method for calculating amplitude and period of selfoscillation is obtained. Finally, an example of calculating amplitude and period is presented. The deduced results have indicated that hysteresis loop is the substantial cause for presence of selfoscillation, but dead zone can subdue selfoscillation. The system with hysteresis loop[1] which was investigated by Andronov and Bautin has been extended in this paper.  本文应用相空间和逐点变换法研究具有滞环和不灵敏区、无恢复力的二阶系统。将各种可能的运动状态用相轨迹表示在相空间中，论证了相空间的拓扑结构。将参数平面划分为稳定区和自振区。并且得到计算自振振幅和周期的精确方法，最后还给出了算例。 分析结果表明，系统中的滞环是引起自振的根本原因。不灵敏区有抑制自振的作用。 本文推广了安德洛诺夫等人的研究结果［１］，因为他们只考虑了滞环的作用。  In this paper the dominant modes (quasi TE11mode) in circular waveguides filled completely or partially with tangentially magnetized ferrite are studied for the general casethe diagonal components of permeability tensor μr =μz≠μθ. It is found that the characteristic equations for right hand and left hand circularly polarized waves are identical. Consequently, there exists no difference between the propagation constants of these waves, the rotation of plane of polarization is absent when a linearly polarized... In this paper the dominant modes (quasi TE11mode) in circular waveguides filled completely or partially with tangentially magnetized ferrite are studied for the general casethe diagonal components of permeability tensor μr =μz≠μθ. It is found that the characteristic equations for right hand and left hand circularly polarized waves are identical. Consequently, there exists no difference between the propagation constants of these waves, the rotation of plane of polarization is absent when a linearly polarized wave travels through the waveguides. We conclude that these waveguides can be used as polarization insensitive phase shifters and the results of the reference[3, 7](the propagation constants for right hand and left hand circularly polarized waves in these waveguides are different and when a linearly polarized wave travels through the waveguides the plane of polarization is rotated) are questionable.  本文研究了普遍情况下(张量导磁率对角分量μ_r=μ_z≠μ_θ)完全填充和部分填充圆周切线方向磁化铁氧体的圆波导中的主模(准TE_(11)模)。在这种波导中,右旋和左旋圆极化波的特征方程是相同的,因此,它们的传播常数也是一样的;而当线极化波通过这种波导时,不出现极化面的旋转。我们得出结论:这种波导可用来制作极化不灵敏移相器;而文献〔3、7〕中的结果(在这种波导中,右旋和左旋圆极化波的传播常数不相等;当线极化波通过它时出现极化面的旋转)是有问题的。   << 更多相关文摘
