Physical model of computer box is established and through analyzing the changing curves of change of electromagnetic field with time and change of coupling coefficient with frequency, the coupling regulation of electromagnetic on computer box is obtained. It is as follows: electromagnetic pulse has a great effect on components of computer box through apertures and slots, the coupling energy in the box increases first and then decreases. The existence of components decreases the shielding effectiveness and resonant frequency.

建立计算机机箱的物理模型，通过分析机箱内的电磁场随时间的变化曲线和耦合系数随频率的变化曲线，得到电磁脉冲对计算机机箱的耦合规律：电磁脉冲可以通过孔缝进入机箱内部，对机箱内元件的瞬间影响较大；机箱内的耦合能量是先增加后减小；元件的存在使得机箱的屏蔽效能降低，谐振频率下降。

奥沙普秦玻璃酸钠凝胶的流变学实验结果显示，药物玻璃酸钠凝胶具有假塑性流体特性，在低剪切频率时具有较高的黏度，而在高剪切频率时具有较低的黏度，有利于制剂在皮肤表面的涂布和黏附。

They are mainly: the probe-fed square patch antenna with shorting pins,and the probe-fed rectangular patch antenna with a pair of wide slits (E-shaped patch). The analyses were carried out using method of moments software package. It is shown that the probe-fed square patch antenna can be made resonate at three different frequencies of 1.83 GHz,2.16 GHz and 2.74 GHz respect...

同时，采用基于MOM的软件包分析了天线性能，证明方形天线可以工作在3个频率点，即1.83GHz、2.16GHz和2.74GHz，其最大的增益达到9.4dB；E形天线工作在2.13GHz和2.5GHz，当中心频率为2.4GHz时，带宽达到33.33%(反射损耗≤-10dB)，其最大增益为9.25dB。

Polymorphisms in ESRa gene and association with egg production traits The SSCP detection of 5" flanking regulation region and intronl in ESRa gene showed that two genotypes were detected in 5"flanking regulation region of blue eggshell chicken.

ESRa基因多态性与产蛋性状关系 ESRa基因5侧翼调控区和内含子1区经PCR-SSCP检测，发现绿壳蛋鸡5例翼调控区有两种基因型，两等位基因C的频率为0.86，D的频率为0.14。
