Finally, the four-unit cylindrically conformal microstrip antenna array is processed and tested. Testing results indicate that, the input VSWR of the antenna array in the vicinity of 1.575GHz is less than 2, the omni-directional performance good, 3dB bandwidth is about 90 degree on axial plane, right-hand circularly polarization good. Overall performance of the antenna array satisfies the design requirements.
对仿真获得的四单元柱面共形微带天线阵列进行了加工测试,测试结果表明该天线阵列在1.575GHz附近工作频带内输入驻波小于2,柱面法向平面全向性良好,轴向平面3dB波瓣宽度约为90。,右旋圆极化效果良好,天线整体性能达到工程设计要求。

The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.
猪是多胎动物,从猪卵巢上获得的卵母细胞数量虽然较多,但成熟度比较低;由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内,跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应;如果卵胞质成熟或活化程度不够,加之圆形未成熟精细胞成熟度比较差等原因,很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足,引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等,使ROSI显微受精失败。

Take the opportunity of this project, theoretical and experimental researches on the high-efficiency evaporator used in a large quick-freeze equipment have been done. The main work of experimental research is as follows:(1) Compare and analyze the influences of structural parameters on the heat transfer coefficient of an evaporator. The calculation results show that, under non-freezing conditions, the structure possessing the highest heat transfer coefficient is the one with circular fins, equilateral-triangle arranged small tubes and varying fin-spacing.
主要做了以下几方面的试验研究工作:(1)对不同翅片形状、管径大小、翅片管排列方式,以及是否带波纹等结构参数对蒸发器传热系数的影响进行了比较分析,得出在不结霜工况下,具有最高传热系数的蒸发器结构是圆翅片小管径正三角形排列等节距结构的结论。
