This article first antenna, microstrip theory, the circular polarization technology, the theoretical discussion, in this based on the microstrip antenna of circular polarization method - corner square microstrip antenna, and has done a design simulation , and then do the design and further research to improve and eventually get a resonant frequency (S11 reflection coefficient corresponding to the minimum frequency) for the 1.5GHz and 1.43GHz, the frequency of circular polarization for the 1.46GHz, S11 is less than -10dB relative bandwidth, the VSWR is less than 2 is about 8.8% relative bandwidth, axial ratio less than 3dB relative bandwidth of about 2.2% of the right circular polarization microstrip antenna design case, which proved very good the circular polarization microstrip antenna theory, also fully confirmed by a square corner design is a practical program, and select the appropriate regulation of sticks is indeed able to improve the performance of the antenna.

本文先对天线、微带理论、圆极化技术等进行了理论论述，在此基础上，提出圆极化微带天线的实现方法——切角方形微带天线，并对此做了设计仿真，后又对这一设计方案做了改进及进一步研究，最终得到一个谐振频率（反射系数S11 的最小值所对应的频率）为1.5GHz和1.43GHz，圆极化频率为1.46GHz，S11 小于-10dB 的相对带宽、驻波比小于2 的相对带宽约为8.8%，轴比小于3dB 的相对带宽约为2.2%的右旋圆极化微带天线的设计案例，从而很好的印证了圆极化微带天线理论，也充分证实了切角方形是一种切实可行的设计方案，而选取合适的调节枝则确能提高天线的性能。

After two-cluster testing,branch length testing and relative rate testing ,two sequences(Melantitta nigra and Aythya americana) of 15 Cty b sequences were deleted because thek evolutionary rate were heterogeneous. The divergence between Anseriformes and Galliformes was chosen as an anchor point. Nucleotide sequence and amino acid sequence of 13 sequences data set was used to calibrated Anatidae molecular clocks. The results indicated that amino acid sequence is better than nucleotide sequence when divergence time is calculated with two kinds of sequences. The reliable divergence time of Anatidae were estimated with """"1+2TiTv"""" model.

经过二簇检验、分枝长度检验和相对速率检验，删除2条速率不恒定的序列后，用剩余的13条序列，以鸡形目与雁形目的分歧时间(89.8MYA)为锚定点，用顺序标定法标定鸭科鸟类分子钟的分析结果表明，用&1+2TiTv&分析得到的鸭科鸟类的分歧时间比较可靠；氨基酸序列用泊松校正模型和Γ模型估计的分类单元间的分歧时间则比较一致，表明氨基酸序列更适合用于鸭科鸟类分子钟的研究；用同一基因标定分子钟时，较长序列得到的结果标准误比较小；与核苷酸序列相比，氨基酸序列更适于用作分子钟的标定。

He stared at the small flower on the tip of the karnikāra outside the windows. This was his second assumption: He felt that this tasteless and gorgeous life, like the milky liquid excreted by the body was now flowing in his wife's stomach. He imagined that perhaps he was already inside the stomach of this stuporous woman sleeping next to himself, staring at the karnikāra flowers.

他把视线停留在窗外的牙皂树梢的那枝小花朵上，这是他的第二个假设；他觉得这个无味艳丽的生命，亦如体内排泄的乳色液体，如今在妻子腹内飘曳，他想或许自己已在身旁这个昏睡的女人的腹中，凝视牙皂花朵。

The main reason causing the defects and low angle boundaries in SC casting is the perturbations of heat flow and the slight misorientation at the S/L interface. An uniform and unidirectional heat flow is required to produce a single crystal casting free of low angle boundaries or splaying

单晶组织中由于晶体取向与热扩散场综合作用因素造成的亚单元生长形态的改变是造成单晶缺陷的主要原因，控制均匀、严格单向性的热场，并利用单晶生长的各向异性特性，可以避免发散型枝晶组织和小角度晶界的出现。

Guns with the least 'leakage' are best, so a sealed breech (e.g. bolt action) is preferable and can be suppressed to the point that the "click" as the striker or hammer falls is the loudest sound of firing.

渗泄&最小的枪枝效果最好，所以枪膛密封的结构是最宜采用的方式，对这类枪的抑制效果能做到使射击时发出的最响的声音是击针或击锤落下时发出的&嗒声。

Beautiful green dragonfly, fly it lightly, the sharp reversal of the time, shoot kissed, you still remember how you, with love and curiosity, gazed at this lovely little wizard, I should be this beautiful Green dragonfly wear on your head, so she always轻吻with your hair, as I kiss your body falls, and numerous green diamond crystal and beautiful, elegant shape, the dragonfly's body was light most.

美丽的绿蜻蜓，它翩跹飞舞，急转之时，吻了一下枝梢，您还记得，您怀着何等的爱意和好奇，凝视着这只可爱的小精灵，今天我要把这个美丽的绿蜻蜓戴在你的头上，让她时刻轻吻着你的秀发，就像我的吻落在你的身上，无数的绿色水钻晶莹而美丽，精致的造型，把蜻蜓轻盈的身体表现得淋漓尽致。

Based on the revised system,the vine life form spectrum analysis shows that the phanerophyte lianes are absolutely dominant,accounted for 72.7% of all vines,followed by the geocryptophyte vines(17.5%),the hemicryptophyte vines(6.2%),the therophyte vines(2.7%)and the chamaephyte vines(1.5%).

对本区生活型分析的结果表明，中国亚热带东部藤本植物的生活型谱是以高位芽藤本占绝对优势( 72 。7%)其次为地下芽藤本( 1 7.5%)、地面芽藤本( 6.2 %)、1年生藤本( 2 。7%)和地上芽藤本( 1 。5%)，除地下芽藤本比例略高外，与亚热带常绿阔叶林生活型谱十分接近，具有比较明确的生态学意义；地下芽藤本比例略高的原因可能是由于该类藤本具有地下贮藏器官，因此有利于次年春天迅速的抽生攀援枝，较其他草质藤本更优先占领光合空间，这是对区域小生境长期适应的结果。

Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.

结果表明：毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小，是较为稳定的指标；展叶期施肥处理（处理1）能显著增加单株立竹的叶片数量，到7月底，其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥（处理2）提高14.8%和13.7%，比不施肥提高27.6%和24.5%；冠层14~17档是单枝叶片数量最多的区域，施肥能增加各枝盘叶片的质量，但对林冠重心的分布无影响；单叶叶面积稳定后（6月），处理1的叶绿素测定值和光合速率显著高于处理2和对照，而处理2与对照间无显著差异。

Life. But the intrinsic way of the Internet by wire confines accessing and using of the network information.

然而，Internet固有的有线连接方式大大限制了人们对网络信息的访问和使用。

I have a strong persuasion that this is true .

我坚信这是正确的。
