    The Kwangsi Gymnasium is situated by the Yong River in the urban district of Nanning. It accomodates 5,450 spectators and has a total floor space of 8,210 square metres. The competition hall has a rectangular plan with a span of 54 metres and a length of 66 metres. The arena can be used for basket-ball and volley-ball matches, gymnastics, acrobatics as well as mass rally. The hall has 1,730 seats in 8 tiers downstairs and 3,674 seats in 11 tiers in the balcony. It has a ceiling height of 16 metres, providing a cubic volume of 8 cu.m. per seat.Because of the sub-tropical climate in Nanning, the design has carefully considered the natural ventilation of the competition hall. The problem has been resolved by arranging the main fagades to face south and north so as to direct the summer prevailing wind to blow at right angle with the major axis of the building, and by utilizing the windows above the grandstand on the south wall and the spaces between the tread plates of the grandstand seats to let draught pass through the corresponding parts on the north wall. The treatment mentioned above can also provide adequate natural light for sports competitions in the daytime without the necessity of artificial illumination. The shortcoming is that during the hours of strong wind table-tennis and badminton matches can only be held by closing part of the windows. Moreover, the increasing of ceiling height makes the top tiers of the balcony seats steeper in gradient.According to the principle of economy and thrift, the architectural form has been organically integrated with functional requirements, structural system and building materials. The open-type structure of the grandstand, the crisp style of the colonnade and the out-stretched cantilevered gallery, as well as the light toned exterior finishes and the luxuriant sub-tropical plants, sufficiently present the striking characteristics of architecture in South China.The gymnasium is built with a cast-in-situ reinforced concrete frame. The competition hall, 54 m. by 64 m., is topped with tubular three-dimensional steel trusses, which are light and comparatively rigid. Artificial lighting provides an illumination level of 500 luxes in the central part of the arena and 250 luxes along its sides. Practice has proved that both the illumination level and its uniformity are comparatively satisfactory.

    In 1975 we synthesized the sex pheromone of the oriental fruit moth, Grapholitha molesta (Busck), cis-8-dodecenyl acetate, and field trials were conducted with traps baited with the synthetic pheromone in a peach orchard near Peking in the summer of 1975 and the spring of 1976. The results of field trials show that the attractiveness of the synthetic pheromone is very good; the addition of a small percentage of the trans isomer to cis-8-dodecenyl acetate can increase the attractiveness, and the addition of 10%...

    In 1975 we synthesized the sex pheromone of the oriental fruit moth, Grapholitha molesta (Busck), cis-8-dodecenyl acetate, and field trials were conducted with traps baited with the synthetic pheromone in a peach orchard near Peking in the summer of 1975 and the spring of 1976. The results of field trials show that the attractiveness of the synthetic pheromone is very good; the addition of a small percentage of the trans isomer to cis-8-dodecenyl acetate can increase the attractiveness, and the addition of 10% the trans isomer gives the best capture. It is interesting to note that the synthetic pheromone is also attractive to males of the summer fruit tortrix, Adoxophyes orana (Fischer von Roslertamm), another important pest, whose sex pheromones are cis-9- and cis-11-tetradecenyl acetates. The optimal attractiveness for this insect requires 12% the trans isomer in cis-8-dodecenyl acetate.Some factors influencing the captures of the male oriental fruit moth have been investigated in field trials. In good weather, catches were greatest in the evening, i.e., at 17:00-18:00 in spring, and 20:00-21:00 in summer, Little or no oriental fruit moths were captured during the periods of strong wind or heavy rain.

    1975年我组合成了梨小食心虫性外激素顺-8-十二碳烯醋酸酯,并于1975年夏季和1976年春季在北京市通县果园进行了田间诱蛾试验。试验结果表明:合成的梨小食心虫性外激素具有强烈的诱蛾活性。在顺-8-十二碳烯醋酸酯中加入少量反式异构体能显著提高诱蛾活性,当反式异构体的含量为10%时活性最好。在田间试验中我们还发现,这种合成的昆虫性外激素对另一种重要害虫棉卷蛾(已知它的性外激素是顺-9-和顺-11-十四碳烯醋酸酯混合物)也有一定引诱作用,当反式异构体的含量为12%时诱蛾活性最高。我们对影响梨小食心虫诱蛾效果的其它因素进行了观察和研究。在一般天气下,梨小食心虫的交配活动主要在傍晚前后进行,春天在下午5—6点,夏天在下午8—9点,这时捕蛾量最多。刮大风或下大雨时它们很少活动,几乎捕不到雄蛾。

    The meridional components of 850 mb wind over the equator at 105°E, 120°E and 150°E from June 15 to September 12, 1976 is analysed by the use of the spectral method. By comparing the power spectra of the meridional wind components at these locations with that of the surface pressure in Australia, we find that all the power spectra show 15 day cycle, except that at 120°E.The south wind components cross the equator at these three longitude are also calculated. The strongest wind is at 150°E,...

    The meridional components of 850 mb wind over the equator at 105°E, 120°E and 150°E from June 15 to September 12, 1976 is analysed by the use of the spectral method. By comparing the power spectra of the meridional wind components at these locations with that of the surface pressure in Australia, we find that all the power spectra show 15 day cycle, except that at 120°E.The south wind components cross the equator at these three longitude are also calculated. The strongest wind is at 150°E, the weaker one is at 105°E, and the weakest wind, which is smaller than the other two by 1-2 m/s, is at 120°E.Thus, it is concluded that there are two main low-level cross-equator air flows from Australia during the northern summer. They located at 105°E (Singapore) and 150°E, (Bismarck Archipelago), respectively.

    本文用波谱分析方法,对1976年6月15日至9日12日赤道上105°E、120°E和150°E附近850毫巴的经向风分量作了分析。将这三处经向风功率谱与同一时期澳大利亚地面气压的功率谱进行比较,我们发现:105°E、150°E的功率谱和澳大利亚地面气压的功率谱都有明显的15天周期,而120°E克的功率谱则没有。 我们还计算了赤道上这三个经度的南风分量。风速最大的是150°E,其次在105°E。120°E的风速比前二处小1—2米/秒。 由此我们认为:夏季来自澳大利亚的气流有两个通道,一个在105°E(新加坡)附近,另一个在150°E(俾斯麦群岛)附近。
