Chinese markswoman Guo Wenjun broke the Olympic record for the women's 10m air pistol with 492.3 points, winning China the 2nd gold medal for shooting at the Beijing Shooting Range Hall Sunday morning. The Olympic debutant, a 24-year-old from Shaanxi, ranked 2nd among 8 finalists after the qualifying round, and overturned the leading Russian Natalia Paderina in the finals.

中国女子射击选手郭文珺10日上午在北京射击馆举行的奥运会女子10米气手枪决赛中发挥出色，以492.3环的成绩为中国队摘得本届奥运会上的第2枚射击金牌。24岁的郭文珺来自陕西省，此次是初次参加奥运会比赛。10日在预赛中她以第2名的身份进入决赛，但在决赛中成功超越了预赛成绩最好的俄罗斯选手帕特琳娜。

Gently shake youth Campanula ring, a pleasant voice on the heart attack, looked up rays in the halo of colorful dreams, a few heart will indulge in the glory of touching: the stream of history, the splendid ancient Chinese poem so elegant that the idea of flying the look, clean up one's soul and beautify their own temperament; breathing poetry of the text in the mellow air, let poets of sentiment or feeling melancholy; then Qingli poetic, sincere love, dream The gorgeous cast of human soul, the soul of the strokes used to write their own lines, to the life of paper left on a clean page.

轻轻摇响青春的风铃，一阵悦耳声袭上心头，抬头仰望霞光中五彩梦的光环，心几就会沉醉在那动人的光环之中：从历史的小溪里，掬起古人灿烂的诗句，让那飘逸的思想、飞动的神采，荡涤自己的灵魂，美化自己的气质；呼吸诗文中醇厚的文气，感悟诗人们放达抑或忧郁的情怀；再把诗的清丽、情的真挚、梦的绚烂投人心灵之中，用灵魂的笔触写出自己的诗行，给生命的纸页上留下一笔清澈。

After analyzing the performance anduncertainty of the DDPM vortex flowmeter in gas-liquid bubble flows, the vortexflowmeter-Venturi tube combinative method using the vortex flowmeter and the Venturi tube as measuring cells was put forward, the measurement model based on thevortex frequency and the Venturi differential pressure was established, and it showsthat the relative errors of this method for the mass flow measurement of bubble flowsare within±5%. Furthermore, the flowrate and volume void fraction of bubble flowswere obtained using a single DDPM vortex flowmeter through the relationshipbetween the frequency and amplitude of the circumferential DDPM signal, and resultsdemonstrate that the relative errors of the flowrate and volume void fraction of bubbleflows are within±5% and±10% respectively, which indicates the broad applicabilityof this method to large numbers of engineering fields.

According to the existent problem of the running water film deduster which included the more pressure drop and the efficiency of low removal dust,the method was discussed by applying venturi and rotating-stream-tray and spraying and demister to reconstruct the old deduster.

针对文丘里水膜除尘器运行中存在的压降过大和除尘效率过低等问题，采用文丘里+旋流板+喷淋+折流除雾器的方法对原有除尘器进行改造。改造工程应用表明，该方案的阻力和除尘效率在理论上的分析与实际应用相一致，在文丘里喉管气速 40m/s，液气比 0 。5L/m3 ，喷淋液气比为 1.5L/m3 时，除尘效率达到 95 %以

When the night got down quietly, the glory which seemed to be the jade fell into the entire earth and space looking like the Milky Way waterfall. It suddenly shone the clear bright. The silent magnolia looking like a literary-style girl by now on, calmly bathed in the fantastic night. In another hand, it was decorated gracefully and naturally by the flowers which were standing upright the branches showing off some extent of grazioso pretty. Looking the suitable ray of light and paying the full attention to the top of the tree gave me more interest.

当夜沉寂下来，一丝风也没有，玉一般的光辉似银河瀑布匀匀地倾洒向整个大地和空间，映照出一种清晰的明亮，沉默不语的花树这时就如一个文气的姑娘，静静地沐浴在夜的飘渺之中，而那挺立枝头非常大方的花又把她装点得婀娜多姿，显出一派幽幽的靓丽。

This thesis deals with oil-water flow rate measurement using a venturi and develops a differential pressure-based two-phase flow rate measurement model, which does a terrific job with the use of a water fraction device. Meanwhile, Coriolis flow rate meter is also studied in the oil-water two-phase flow measurement and a SVM-based single-phase flow rate prediction method is proposed, realizing the prediction of single-phase flow rates. To overcome the disadvantages of both venturi and Coriolis flow meters, a double parameter measurement method is put forward, which combines the two meters and solves the problem of oil-water flow rate measurement. Last but not least, on the basis of the study of two-phase flow, a device for the separation of gas and liquid is designed and realizes the flow rate measurement of three-phase flow as oil, gas and water.
