1. The deuterium contents of two,bittern samples obtained from Chiaochou Bay in Tsingtao Locality and Kwangchou Bay in Chenkiang Locality were determined by float method. Sp. gr. of Shantung sample is 1.240 (28.0?Be') and that of Kwangtung sample is 1.260 (29.7° Be′). A sample:from Yellow Sea was chosen .as a standard for comparison.All determinations were carried out after normalization of O18 in the sample, by means of CO2-NaHCO3 equilibrium method. In. experiments employing a stream-lined spindle-shaped float and setting the observation region of floating in the middle portion of liquid. column, therefore, a larger range of linear relation between temperature and velocity (rising or falling) of float is obtained, that is, temperature range is±0.33℃ and the velocity range is ±0.26 mm/sec.2.Determined results show that the density of Shantung bittern sample (28°Be′) is 4.208 r higher than that of standard sea water sample, that is, the D content of Shantung bittern is 0.0037 mole % D2O higher than that of the standard (Corresponding to 24.03% of D content of standard sea water sample), the density of K,wangtung bittern sample (29.7°Be′) is 6.250 r higher than that of the standard, that is, the D content of Kwangtung bittern is 0.0058 mole % D2O higher than that of the standard (Corresponding to 37.66% of D content of standard sea water sample). The max. experimental error is ±0.6 7.3.Comparing the determined results of these two samples from Shantung and Kwangtung we can see that the Kwangtung sample is more abundant in heavy water content (through °Be′ of two samples are not entirely the same, the density difference is still apparent). This agrees with the expected results caused by the evaporation difference which is due to the latitudinal difference between the two localities (Chenkiang situated at 21° north latitude and Tsingtao at 36° north latitude).4.The density difference between sample water and standard water shows that after solar evaporation of sea water and salting out of sodium chloride the D content in bittern is concentrated as expected. Thus, highly concentrated bittern may be used as raw material for production of heavy water--a valuable information for the comprehensive utilization of sea water and bittern.

1.我们用浮沉子法测定了胶州湾青岛地区及广州湾湛江地区盐田析盐后苦卤中重水的含量,山东苦卤此重为1.240相当于28.0°Bé,广东苦卤比重为1.260相当于29.7°Bé,并用黄海某区海水作为标准进行此较。所有测定都在用CO_2-NaHCO_3平衡法使氧同位素正常化以后进行的。实验中采用了流 线型梭把式浮沉子,并使浮沉子升降区观察范围设在液柱中部,获得了较大的浮沉子升降速度与温度间直线性关系的范围。温度范围±0.33°C。速度范围±0.26毫米/秒。 2.测定结果表明:山东苦卤(28°Bé)密度较标准海水高出4.208γ相当于0.0037克分子%D_2O,重水含量较标准海水高24.03%。广东苦卤(29.7°Bé)密度较标准海水高出6.250γ,相当于0.0058克分子%D_2O,重水含量较标准海水高37.66%。 3.比较广东与山东二份样品测定结果,可以看出广东苦卤中重水含量有更多富集(虽然二者°Bé不尽相同,但密度差仍旧是显著的)。这与湛江、青岛两地的纬度差异(湛江——北纬21°,青岛——北纬36°)而引起的蒸发差异所应导致的预期结果是一致的。 4.样品水与标准水的密度差证明海水经自然蒸发析出氯化钠以后...

New methods of transonic experiment in the ballistic range are presented in this paper. Two special launching techniques are used on a two-stage light gas gun, namely the filling gas techniques which can be used to obtain a projectile velocity in the subsonic range and the low filling condition technique which can be Used to reach transonic and supersonic ranges. Since initial acceleration of model is lower in the subsonie and transonic cases, models can be launched with stable attitude and undamaged configuration. In addition, there is no support disturbance and small wall effect, so that the ballistic range has special advantage for transonic test. Using the f orementioried techniques, clear photographs of flow field around spheres in transonic cases have been obtained. Comparing with supersonic and hypersonic cases the stand-off distance of shock wave, the neck width, the position of separation point and the wake are obviously quite different. Two photographs of flow field around a sphere at M = 1.01 and M = 0.99 have been obtained and produced valuable information. Finally a tentative idea for raising Reynolds number up to 10 by increasing pressure and decreasing temperature in the-range is described.

本文介绍用弹道靶作跨音速试验的新方法,在二级轻气炮上采用了二个特殊的新技术:充气放炮能发射模型达到亚音速,低充填条件能发射模型达到跨、超音速。由于初始加速度较小,发射的模型外形完整,姿态稳定;加上没有支撑干扰和小洞壁效应的优点,使弹道靶设备在跨音速实验方面有特殊的优越性,用上述技术得到了圆球跨音速流场的清晰照片,其中击波脱体距离、分离点位置、颈部宽度、尾迹形状与超音速、高超音速流动比较有明显变化。文中M≈1.010和M≈0.99的二张全流场照片是十分有意义的。最后提出一个想法,用靶场加压、降温的方法可以提高雷诺数直到10~7以上。

Bovine trypanosomiasis spreads widely in Ethiopia, producing a serious menance to cattle. An investigation on epizootiology of bovine trypanosomiasis was carried out in order to provide valuable information as the basis for devising control measures. 5171 blood-smear samples collected from Bahar Dar region (five places) were examined during 1978—1979. It was found that 576 cattle were infected with trypanosomes, infcotive rate being 11.4%。All of them were identified as Trypanosoma vivax morphologically. Results obtained from the investigation on seasonal dynamics of infection revealed that only a few cases occurred from late February to gune & infective rate was below 4%, the lowest period of infective rate in the year. After that, infctive rate rose rappidly to about 10%, lasting grom guly to September and reached to a mach higher rate of about 15% from October to February of next year, being the highest period of infective rate of the year Thence, this disease prevails for seven & half months in this region in a year & the rest period is slack season. These investigative results were disccussed in detail & a suggestion was made for control measures against bovine trypanosomiasis for this region.

牛锥虫病在埃塞俄比亚是一种流行广泛、危害严重的疾病。研究流行病学的目的在于为有效的控制本病提供依据。 1978—1979年间,在巴哈尔达尔地区5个点检查牛血片5171枚,共发现阳性牛576头,感染率为11.14%。病原体经形态学鉴定全部为活跃锥虫。季节动态方面全年呈现三个阶梯:2月下旬至6月,仅有个别病例发生,感染率在4%以下为全年最低期;从7月开始感染率急剧上升至9月均为10%左右;从10月开始感染率进一步上升至翌年2月均在15%左右,为全年最高期。由此可见,该地区全年有7个半月为牛锥虫病的流行季节,其余时间为淡季。对上述结果,结合该地区的地理气候条件进行了较详细的讨论,并提出了防治意见。
