In this paper, the design, construction and characteristics of a 70cm streamerchamber system are deseribed. A very fast pulse with rise time 2 ns and duration 10ns has been successfullyobtained by using a four-spark-gap cylindrical Blumlein line with a 25 stage Marxgenerator (up to 600kV) connected to it. The output pulse of the Blumlein line isthen fed to the chamber, via heteromorphic transmission line with pulse shapeminimum distortion.

In this paper, the design, construction and characteristics of a 70cm streamerchamber system are deseribed. A very fast pulse with rise time 2 ns and duration 10ns has been successfullyobtained by using a four-spark-gap cylindrical Blumlein line with a 25 stage Marxgenerator (up to 600kV) connected to it. The output pulse of the Blumlein line isthen fed to the chamber, via heteromorphic transmission line with pulse shapeminimum distortion. The system are triggered by three-fold large area scintillation counter telescopeto pick up particle of the cosmic ray traversing the sensitive volume of the chamber.The coincidence-counting rate is ~5 particles/min., the resolving time is 10ns, andthe ratio of the true-accidental coincidence is more than 700. The chamber has two 15 cm gaps and is 70 cm long, 50 cm wide, with 30Ω ofcharacteristic impedence. In order to photograph through the electrodes, the central and the ground electrodes towards the cameras are made of 0.2mm diameter beryl-lium-copper wire stands spaced 2 mm apart, with transparency~90%. Pure neon and mixtures of neon-helium gas were used to fill the chamber, oneatmosphere, and a cycling and purifier system were designed to maintain its purity.The gas is passed through type 5A and 13x molecular sieve operated at room andliquid -nitrogen temperature to remove CO_2, H_2O and O_2, N_2, respectively. The im-purities of the chamber gas can be reduced to 0.2% within 2hr., at the gas flow rate500 1/hr. All photographs are taken with one or two oscilloscope cameras on 35mm film of28 DIN. A demagnification 30x and a resolution 30 line pairs/mm at the maximumaperture (f/2) are used. The sizes of the visual streamers were estimated about3 to 4 mm in diameter (view along the E field), and 10 to 15 mm long (view perpen-dicular to the E field). The delay time between the penetration of charged particle and the supply of thehigh voltage pulse on the chamber was ~3.5μs. The system was suggested in June1975. The whole facility began to mount and adjust in January 1979, and the strea-mer tracks were seen on July 26, 1979. We plan to make the performance tests, to reduce the delay time of the system,and to improve the chamber suitable for use in high energy accelerator and cosmic-ray experiments in the near future.

This paper gives a brief account on the design for the first two China-built railway bridges of prestressed concrete through girder bridges with spanof 20m(double-track) and span of 24m(single-track)respectively. prestressedconcrete through girder is a through-type structure composed of two mainbeams on both sides and a floor slab in between, with the outstandingadvantage of less height from the bottom of bridge girder to the top of rails.The structure of the two bridges are briefly introduced in the paper,and the design principle based on theory and on tests are specially empha-sized. The topics covered in respect of the design details are: layout of theducts, the sequence of prestressing, the governing stress, the stresses atcorners etc. In addition, some technical tests and their processes as well asthe results of the traffic tests after conctruction are also included.

This article introduces mainly the structural characters、its applying conditions and strength calculation etc.of the following lifting lugs;1.ring type lifting lug at tower top; 2. shaft-through type lifting lug; 3.plate type lifing lug; 4.tube-shaft type lifting lug and 5. mixed type lifting lug.In strength calculation;for the ring type lifting lug,when the tower is in horizontal position,besides correcting the bending strength of the root of the lifting lug.th shearing strergth of bolts should also be calculated.For the supporting plate,the theory of fla plate concentrically loaded and rigidly fixed at circumference can be used for calcula- tion.For the shaft-through type lifting lug.besides correcting the strength and the stability of the lifting shaft,the local influences of the supporting point of the lifting shaft to the cap ofi tower top should also be considered.For the plate type lifting lug,the strength calculation should include the squeezeforce of shaft hole,the shearing force of lifting lug and bending strength of lifting shaft etc,For the tube-shaft type lifting lug,calculation can be made ac- cording to the theory of short cantilever beam.For the mixed type lifting lug with sup- porting lever system,it can be simplified to linear static indetermination structure and calcu- lated as the articulated pull-rod.

本文主要介绍了下列几种吊耳的结构特点、应用条件及强度计算等问题:1.塔顶环式吊车;2.穿轴式吊耳;3.板式吊耳;4.管轴式吊耳;5.混合型吊耳。在强度计算中:塔顶环式吊耳,在塔设备卧态时,除应校核吊耳根部的抗弯强度外,还应校核螺栓的抗剪强度;支承板可按周边刚性固定受集中荷载的平板理论计算。穿轴式吊耳,除应校核吊轴的强度及稳定性外,还应考虑吊轴支点对塔端部封头的局部影响。板式吊耳,其强度计算包括耳板轴孔挤压、耳板剪切、吊轴弯曲等。管轴式吊耳可按短悬臂梁理论计算。带支撑杆系的混合式吊耳可简化成一次超静定结构,设支撑杆系是两端铰接的受拉杆件而后计算。
