Fill a tulip-shaped glass with red wine to one third of a full glass (5cm from the foot of the bottom).Observe the wine. Lean 45 degrees to check its color against a white background. Fine dry red wine looks clear and glossy. By observing the color and tone of the wine, you coukd make good judgment about its maturity. Usually the deeper in yellow tone it looks, the more aged the wine is; the paler in color or deeper in purple tone it looks, the less aged the wine is.Smell the wine. Gently shake the glass for better contact between wine and air until the aroma of the wine evaporates enough. Reach your nose into the glass, smell gently and quickly. Fine red wine is rich in aroma, dense and subtle, with both the aroma from grape and the matching oak fragrance.Taste the wine. Take a deep sip, simultaneously draw in the air over the wine, whirl the wine inside every part of your mouth, fully appreciate its flavor before swallowing. Sense the aftertaste and make a good judgment of its potential quality.

试酒 首先，将红酒倒入郁金香型杯中，倒至酒杯的三分之一处（距杯角约5厘米处）即可，倾斜45度，对着白色的背景看颜色，好的干红葡萄酒应该是清澈、有光泽，根据葡萄酒颜色的深浅及色调，也可以判断出红酒的成熟度，同常红葡萄酒颜色越深、黄色调越重酒越老，颜色越浅、紫色调越重酒越年轻；闻香味，酒杯轻轻晃动，促使酒与空气接触，使酒的香气释放出来，然后将鼻探入杯中，短促的轻闻，红葡萄酒香味丰富、浓烈而复杂，既有葡萄本身所发出的果香，又有因在橡木桶中醇化而产生的丰富和谐的橡木香；然后品尝味道，深啜一口，同时吸入酒上方的空气，并让酒在口中打转，使之到达口腔的每一个部位，充分品尝它的味道，最后将酒下咽，同时感觉酒下咽喉后留在口中的滋味，体会它的余韵以判断酒是否有潜质。

The operative area was examined with light microscope, electronic microscope, and the proliferating cell nuclear antigenwas detected. Results In CsA group, intraocular pressure was significantly lower than that in NS group(P＜0.05), and more functional filtering blebs were observed. Less fibroplasia and proliferative cells, less bioblast and less active caryotin in fibrocyte were found in CsA group than that in NS group. No serious mcomplicaton was found in both group.

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。

In common glass fiber reinforced polyolefine pipe, when the volume faraction is less than the critical value, the glass fiber can not act as reinforcement, on the contray, it would reduce the whole intensity of the compound material. However, when extruded in combined stress field, the extend intensity of the compound system increases when the volume fraction of glass fibers is less than the critical value. When the glass fiber volume fraction is higher than the critical value, the required glass fiber volume fraction of compound fibers extruded in the combined stress field is less than theory value.

一般玻璃纤维增强管材在常规挤出时当添加的玻璃纤维体积含量小于临界体积分数(当添加的玻纤的复合体系拉伸强度等于基体聚合物材料的拉伸强度时的玻纤体积分数)时，玻纤起不到增强的作用，反而会使复合材料的整体强度降低；但在复合应力场下挤出时，当添加的玻纤含量小于临界体积分数时，复合体系的拉伸强度不但没有降低反而升高了；当添加的玻纤含量大于临界体积分数时，复合体系要达到同样强度，经过复合应力场的玻纤增强管材需要的体积分数小于理论值。
