The results of its 1D test demonstrate that the MARED code is suitable for simulating implosions on different devices and with a wide range of load parameters. Combination of the wire-array Z-pinch experiment simulation and analysis shows that under the same load conditions, the X-ray radiation power produced by the tungsten wire-array implosion is much greater than the power generated by the aluminum wire array. With the same load current, the greater load mass gains the lower X-ray power.

结合丝阵Z箍缩实验的数值模拟和分析表明：相同负载质量条件下，钨丝阵内爆产生的X光辐射功率远大于铝丝阵产生的X光功率；相同负载电流条件下，负载质量越大，计算得到X光功率越低；X光功率随着负载电流增加而增加。

For narrow-band signals, three uniform linear arrays, whose grating lobes are not overlapped by setting the angles between the arrays and the same pointing of main-lobes, are used and then multiplication of three patterns is operated to reduce the grating lobes of large-spaced array, which makes the array operate in broad band. For wideband or ultra-wideband signals, array pattern in the whole frequecy band is identical by designing the frequency-dependent weighting coefficients based on the Bessel function, and therefore grating lobes in high frequency parts are suppressed.

对于窄带接收信号，利用三个相交的大间距均匀线阵，通过设置它们之间的角度和主瓣指向相同使各自的栅瓣位置错开，然后把三个方向图相乘从而抑制大间距阵列栅瓣，因而适用于宽频带工作；对于宽带接收信号，利用Bessel函数设计与频率有关的加权系数，产生整个信号带宽内恒定的方向图，从而抑制了高频部分的栅瓣。

With the help of these conditions, computer efficiently searches out many quasi-perfect and double quasi-perfect punctured binary array pairs. The relationships among perfect punctured binary array pair, quasi-perfect and double quasi-perfect punctured binary array pair is presented. Specially, when first and second dimension period of the punctured binary ar

The entire theory systems of the punctured binary sequence pair and the punctured binary array pair are built, which include the perfect punctured binary sequence pair theory, the perfect punctured binary array pair theory, the quasi-perfect and double quasi-perfect binary array pair theory, and the punctured binary complementary sequence pair theory.

定义了屏蔽二进序列偶、最佳屏蔽二进序列偶和奇周期最佳屏蔽二进序列偶，研究了它们的变换性质和存在的组合允许条件，并用这些性质和条件，搜索出若干最佳屏蔽二进序列偶和奇周期最佳屏蔽二进序列偶。

At first, this age-dating approach was used to estimate the age of G-dwarf stars with Th/Nd chronometry. Recently, it has been used to evaluate the age of halo field stars and globular cluster stars with the Th/Eu and U/Th chronometers.

这种方法最初是利用元素对 Th/Nd 来确定 G 矮星的年龄，近年来开始利用元素对 Th/Eu 和 U/Th 来确定晕族场星和球状星团内恒星的年龄。
