In this paper the dimension parameters which influence the electrical properties of the biconical antenna is discussed by means of simulation and experimental test. And a biconical omni-directional antenna array operating within 0.8~3GHz is designed. Its design parameters and the results of the simulation including curves of the VSWR, radiation pattern and the gain within the band are also given.

The antenna has a composite structure of a cage and an asymmetric biconical structure. The impedance bandwidth and radiation pattern bandwidth are enhanced, and the tilting and ripping of radiation patterns are eliminated.

将笼型与不对称双锥结构相结合，展宽了天线的阻抗和方向图带宽，抑制了天线辐射方向图在宽频带内上翘或裂瓣。

A simple connected graph is called bicyclic if it has n vertices and n + 1 edges.

This paper referred to simulating the supersonic double cone inlet" s flow field of ramjet pill assisted range projectiles at a variety of working circumstances, pressure contours, density contours and Mach number contours of inlet" s flow field were given When cone combination, relative location of cone core and cowl lip, the pressure of outlet, inflow Mach number and angle were changed, flow field and performance parameters of inlet can be affected. Simultaneity, productive mechanism and inducing factors of the inlet surge were also discussed. Then the best working conditions and the best model of inlet were obtained.

Finally this paper consideres an applicable case-the symbolic transition graph,then the generalized symbolic observation graph SOG and symbolic congruence graph SCG can be finite,so authors' algorithm is feasible for weak bisimulation and observation congruence.

此时由符号双迁移关系生成的符号观察图和迟符号同余图必为有穷图，因而我们的弱互模拟等价算法是可行的。

In the sonograms of Psittacula Agapornis after the section of right side NXIIts the ascending parts of the tone disappeared. This causes their vocalizations became the descendent-call.

牡丹鹦鹉在断右侧NXlltS后其声图中音调上升支消失，因而其叫声变为以降音调为主的降调叫声；在断左侧NXlltS后的声图中，其基本音以上的谐波成分减弱或消失而在断双侧神经后其声图表现为一系列具有较低基频的宽带谐波谱。

Results One case of 226 Hz tympanograms was type "As" while others were all type "A", of which single-peaked tympanograms was 43.2%(108/250), W-shaped tympanograms was 56.8%(142/250). The abnormal pattern of 678 Hz tympanograms were 74 ears, and the abnormal pattern of 1000 Hz tympanograms were 35 ears. 43 newborns (86 ears) have accepted temporale CT and results showed 30 middle ears with effusion.

结果 226 Hz探测音鼓室导抗图有1耳为As型，其余耳均为A型，其中单峰型占43.2%(108/250)，双峰型占56.8%(142/250)；678Hz探测音鼓室导抗图异常者有74耳，其中65耳为B型，4耳为As型，5耳为C型。1000Hz探测音鼓室导抗图异常者有35耳，其中26耳为B型，5耳为As型，4耳为C型，声导抗测试异常或可疑者43例（86耳）颞骨薄层CT检查显示30耳存在中耳腔积液。

When ATRP of styrene was investigated with 1-phenylethyl bromide/benzyl a,a-dibromide mixture as initiator, the GPC chromatogram shows two elution peaks and the molecular weighs of the peaks are approximately in a 2/1 ratio. It suggests that benzyl dibromide is a difunctional initiator of ATRP of styrene. The analysis of end group using 1H-NMR also proves the result above.

采用1-苯基溴乙烷／α，α-二溴化苄混合引发剂进行苯乙烯的ATRP反应时，所得聚苯乙烯的GPC谱图为双峰，分子量相差一倍，初步证明了α，α-二溴化(来源：ABf399C论文网www.abclunwen.com)苄引发苯乙烯ATRP反应时是双官能引发剂，并用~1H-NMR对聚合物结构进行分析，进一步证明了α，α-二溴化苄引发苯乙烯ATRP时是双端同时增长的。
