The Regulation of braided stream with heavy sediment load calls for a complete change in river regime of a stream course running hundreds of kilometers long. This is only possible by modifying the hydrograph and the sediment production rate of the watershed and by changing the boundary conditions of the stream channel.

The Regulation of braided stream with heavy sediment load calls for a complete change in river regime of a stream course running hundreds of kilometers long. This is only possible by modifying the hydrograph and the sediment production rate of the watershed and by changing the boundary conditions of the stream channel. The construction of reservoir in the upstream basin upsets the equilibrium conditions of the river downstream of the dam, and a change in regime is expected. The braided river, after gradually losing its wandering intensity, will transform into a meandering pattern. At the beginning of the adjustment, the shifting of the main current still exists. The channel will be deepened by the passage of water with much smaller sediment concentration. Yet, on the other hand, the recedence of the bank lines under the attack of the ever-shifting current tends to widen the channel. The eventual modification of the cross-sectional form of the degrading reach depends on the interaction of these two types of forces. At low and medium stages, it appears that the deepening of the channel has gained the upper hand. After the passage of a larger flood when the water overflows the flood-plain, a rapid widening of the channel will take place instead. In as much as the recedence of the bank lines is a threat constantly in existence, every effort should be made to cut down the flow released from the dam to a value smaller than the bankfull discharge of the downstream channel, and bank stabilization works must be started immediately after the completion of the dam. The control of the mean-water channel and the protection of the bank lines should be proceeded hand in hand, with the former as the main measure. It is proposed to modify the river course into a succession of smooth bends such that the thalweg will be fixed along the concave side of the bend and low sand banks formed on the other. By using a smooth curve to guide the flow, the jetties and training walls will be subjected to a force evenly distributed along the bend, and this is beneficial for their maintenance. The protection length of the concave bank depends on the radius of curvature of the bend and on the variability of the flow. According to the experiences obtained from one of the sandy rivers in China, the ratio of protection lengths upstream and downstream of the apex of the concave bank is 2 to 3. In the degrading reach, it is sufficient to stabilize the concave side of the bend only. In the transition and aggrading reaches, underwater jetties should also be built along the bank line at the lower half of the convex side of the bend.

在多沙河流上修建蓄水拦沙水庫以后,下游游蕩性河道将逐漸向弯曲性轉化.如下洩清水不超过下游河道的平滩流量,則河床将以下切为主;如水流继续不断漫滩,則河道将逐漸展寬。固定中水河槽是保护滩地,加速河道調整过程的重要途径,应尽量利用已有节点,增加节点数目,并逐步改善节点外形,使其具有曲度适当的弯道型式。文中根据多沙河流的經驗及模型試驗結果,对河湾平面尺寸、护岸导流工程的布置及結构进行了初步探討.

The problems to be emphasized in strategic development of the work of conserv ation on the loess plateau have been presented in the paper: (1) It is necessary to use the land rationally, through readjustment of the strut cure of agricultural production. Measures appropriate to local conditions are to be taken in the 13 typically different zones of the loess plateau, relying mainly on forestry and animal husbandry, on agriculture as well as stock-breeding, or mainly on agriculture accordingly. (2) Work should be carried on persistently in managing the slopes as well as gullies and improving in a comprehensive way. Management of slopes and gullies, engineering measures and vegetative practice should go hand in hand with one another, each with its specific function. The establishment of basic farmland and its role in promoting comprehensive improvement and devlopement of rural economy as a whole have also been treated of.

本文提出在黄土高原的水土保持发展战略中应着重研究的几个问题:(1)必须合理利用土地,调整农业生产结构。对黄土高原13个类型区,应因地制宜,区分或以林牧为主,或农林牧并举,或以农业为主等三种情况,不能笼统地提出整个黄土高原以什么为主。(2)必须坚持坡沟兼治,综合治理。治坡与治沟,工程与林草,各有作用,不能互相代替,并进一步阐述了基本农田在促进综合治理与整个农村经济发展中的作用。

The state-of-art and prospect for materials and hot working technology for gas-turbines, made in China, were reviewed in the present paper.Materials used for gas-turbine disk, which were loaded with complex stresses and undergone non-uniform distribution of temperature, have been developed starting from stainless steels to super-alloys, since 1940.

The state-of-art and prospect for materials and hot working technology for gas-turbines, made in China, were reviewed in the present paper.Materials used for gas-turbine disk, which were loaded with complex stresses and undergone non-uniform distribution of temperature, have been developed starting from stainless steels to super-alloys, since 1940. Such disks, either formed with casting or forging technology, exhibiting inevitably a series of metallurgical defects, greatly reduce the working life of a gas turbine. So that it seems to be more important to develop new manufacture technology, in order to reduce the metallurgical defects to a minimum, rather than reseaches on new alloying composition.Some advanced technological processes have been developed recently, among then there are powder metallurgy, isothermal hot working and he-at-isopress technology. Due to lack of uniformity, stability and cleanliness, however,powder metallurgy method often renders disk's low-cycle fatigue failure. The later two processes might be the appropriate production methods to improve the working life and utilities of gas-turbine disks, used for manufacture of large thrust to weight ration gas turbines.It is concluded that researches on new alloying compositions and new forming processes should be proceeded hand in hand. For the purpose of improving turbine performance, researches on new forming processes might be more important.

本文评述了我国航空发动机涡轮盘材料及热加工工艺的现状与发展。 在不均匀温度场中承受复杂载荷的涡轮盘,选材由耐热钢逐渐发展至高温合金,经铸造和塑性变形后,存在着许多冶金缺陷。因而,在研究改进材料化学成分的同时,要改变加工方法,以提高材料的工艺性能和使用性能。近年来使用的粉末冶金工艺,也因均匀性、稳定性和纯净度等问题,加工的涡轮盘存在着早期低周疲劳失效的缺陷,同时限制其使用。等温锻造及热等静压工艺,改善了涡轮盘的使用性能,有希望成为大推重比的发动机涡轮盘所采用的工艺方法。 进一步应从寻找新材料和新工艺方法两方面共同着手研究,在一定意义上,后者比前者的作用更大。
