1. In this study which has been carried on since 1949,attempts were made toanalyse factors involved in the outbreaks of stripe rust of wheat in North Chinawith a view of giving some clues for forcasting.Five periods of the developmentof an epidemic of the stripe rust in this region are recognized:(1) the infectionand divelopment period of the rust on wheat seedlings in the autumn,(2) the over-wintering period,(3) the over-springing period,(4) the development period in thelate spring,and (5) the over-summering period.For each of the above stated peri-ods,the degrees of the stipe rust development are described and the main factorseffecting the development are analysed. 2. In the autumn,if field conditions were favorable for infection,the earlier ??the date of sowing,generally the heavier the wheat crops would be rusted.Therewere little or no stripe rust developed when the date of sowing wes later than thelast part of September although the condition might be varied appreciably withdifferent localities.Besides temperature,the period of high concentration of air-bornespores was the most important factor determining the disease severity in the earlysown wheat fields. 3. The stripe rust organism was capable of over-wintering in the form of dormant mycelium within infected leaves under the weather conditions of North Chinaplain.Heavy infection of wheat seedlings was the prerequisite of over-wintering,which was also influenced by micro-environmental conditions such as air temperat-ure,soil moisture and protection from wind.Air temperature was probably the mostessential factor. 4. The dry weather and the low moisture contents in the soil in the earlyspring were unfavorable to the development of the rust.Under these conditions,the over-wintering rust might be completely killed off or much lessened,while hig-her soil humidity usually favored the overspringing of the rust organism.Furtherdevelopment of the disease appeared to depend on the amount and frequency ofprecipitation.However,in flooded areas where the soil moisture was excessivelyhigh,epidemics might occur under dry weather. 5. The over-wintering inoculum was most important for local epidemics in spring,although long distance air-borne spore might also have some influence on the rustdevelopment in the later part of the wheat growing season. 6. Uredospores of stripe rust were not capable of over-summering on volunteerwheats in North China plain.Stripe rust collections from Elymus chinense andAgropyron spp.were capable to infect certain wheat varietes when inoculated arti-ficially,but under natural conditions these grasses appeared to play little part inthe aestivation of this rust in the vast wheat growing areas of North China.Theresults of spore-trapping indicated that Chang-Chia-Kow region and certain partsof inner Mongolia where spring wheats mature as late as the end of August weremost probably the reservoir of over-summering fungus which serve as the mainsource of autumnal infection. 7. Since there are great diversity of types of farming in North China,i.e.,(1)the dry land,(2) the well and river-irrigated land,(3) the low land and river-irrigated land of the mid-part of Shansi Province,and (4) the autumn floodedland,and as the environmental factors effecting the first four stages of stripe rustdevelopment were varied,consequently,the rust development in each type of landwas obviously different from others.The disease struck most severely in the wellor river-irrigated and the autumn-flooded lands. 8. Based on the foregoing results,the writers suggest that by means of timelyobservations and inspections on the stripe rust development during autumn and onthe amounts of the Survival after over-wintering and over-springing along with theweather forecasting data,it is possible to make fairly accurate forecast of the striperust epidemics in North China.

Due to the influence of the vdriation of the temperatures of the surrounding air and water in the reservoir, the decks and the buttresses of a buttress dam often have different temperatures. The writer offers dn approximate method to compute the rather complex stresses thus drisen in the dam. The dam was cut by a plane along the conjunction of the deck and the buttress. Under the action of different temperatures, the deck and the buttress will have different displacements along this plane. Then, a pair of self-balancing shears, equal in magnitude but opposite in direction, was applied along this plane. The distribution of the shears wds deter- mined by the condition that the deck dnd buttress must have the same displacements along the plane of conjunction. After the determinating of shears, the stresses in the dam may be calcu- lated. This method may dlso be used to calculate the stresses due to the shrinkage or swelling of concrete in the deck and to calculate the effect of deck on the stresses in the buttress due to water pressure and weight of concrete.

在气温和水温的作用下,支墩与壩面具有不同的温度,因此而产生十分复杂的温度应力。本文提供一个近似的计算方法。首先将支墩与壩面沿其接触面切开,则在不同温度的作用下,支墩与壩面之间将产生变位差。然后沿此面施加一对本身互相平衡的剪力,大小相等,方向相反,其分布状态由支墩与壩面沿其接触面必须具有相等的变位的条件决定之。剪力求得后,即可计算壩内应力。应用这个方法也可以计算壩面混凝土的收缩或湿胀在壩内所引起的应力以及在水压和自重作用下壩面对支墩应力的影响。这些在按现行弹性力学方法计算支墩壩时均无法考虑。

After the construction of reservior in an alluvial stream, the equilibrium condition of the downstream channel will be upsetted due to the reduction of sediment supply. This will result in a change in the form and gradient of the channel. The direction of the displacement will lead to a reduction of the sediment carrying capacity of the channel, through which the river regains its equilibrium. The whole process is accomplished by the flattening of the bed slope, as suggested by the theories generally accepted at the present. From a study of the fluvial processes of Colorado River and some other streams, it appears that a decrease in channel gradient is one of the three possibilities only, and should not be regraded as an universal rule. In fact, the change in bed slope below an impounding reservoir depends essentially on the geologic and geographic conditions of that area. It is first considered that the channel width does not change materially in the downstream direction. In many of the sandy rivers, there exists, a layer of gravel or pebble below the finer surface material. The inclination of this layer is generally steeper than the present bed slope. After the releasing of clear water from the reservoir, the surface material is carried away and thereby exposing the coarse layer, first near the dam and gradually extended to the downstream. This will result in an uneven erosion along the direction of the flow, and the steepening of the channel gradient is the consequence of such a process. The Colorado Eiver below the Hoover Dam belongs to this case. If the distribution of the bed material in the downstream, direction is more or less uniform, and if there exists no coarse layer within a finite depth below the bed surface, the bed will be degraded as a whole and the channel gradient remains essentially at its initial value. Results of flume study seem to indicate that such is the case. The Colorado Eiver below both the Parker and the Imperial Dam also belongs to this group. Only when there is a base level within a short distance from the dam which controls the depth of scour at that neighborhood, or if ther is a tributary which brings coarser material into the lower part of the reach, will the channel slope below the dam become flatter. On the other hand, if the river is impounded in a gorge and enters a plain not far away from the dam site, the width of the channel on the alluvial fan becomes progressively wider downstream. It is then possible that the depth of degradation decreases in the downstream direction and the slope becomes flatter. This case is well illustrated by one of the rivers in U. S. S. R. It must be realized that no matter how the channel gradient below an impounding reservoir changes, it is mainly through the coarsening of the bed material which makes the channel regains its equilibrium. Two different types of the coarsening of the bed material can be distinguished from the field data available. One of which is the exposing of a gravel or pebble layer below the present alluvium. As soon as this layer is exposed, there will be a sudden jump in the bed material size, and the stream channel becomes stable again. The othertype of coarsening of bed material takes place continuously and at a much slower rate. One often fails to notice the occurence of such a phenomenon, as the size of the bed material only increases in a relatively small amount. Yet, such a small increase in bed material size results in a much significantly rise of the roughness coefficient, by remolding the sand bars on the bed surface. Both the velocity of the flow and the sediment carrying capacity of the channel will be reduced, and the river gradually re-establishes its equilibrium. It is now possible to calculate such a proeess according to the theories on sediment transport and river roughness. Following the coarsening of the bed material, the down-cutting rate of the stream channel decreases with time. Both the flume studies and field measurements indicate that the relationship between the down-cutting rate and the cumulative time of erosion is an exponential one. This study demonstrates that the fluvial processes of an alluvial channel depend very much on the hydrographic conditions of the basin, of which the stream forms a part. One can't visualize the whole aspect of the problem (?)y studying the fluvial proteases through hydraulics, view-point only.

冲积河流上修建水库以后,下游河道将失去平衡。河流为了重新建立平衡,必将发生一系列的变化。本文对这—变化的过程,提出了一些新的概念。根据枢纽下游所在地区的地质地理条件,河流的坡降可以有各种不同的变化。坡降的渐趋和缓只是三种可能性中的一种,不能当做普遍规律来看待。河槽的重新建立平衡,主要是通过河床质的粗化作用。河床质的粗化现象具有两种不同的类型。一种是河床表层复盖物因清水冲刷而外移,露出了底下属于另一地质时代的较粗的卵石层,这时河床质的粒径会发生突变。另一种是由于水流的分迭作用,河床质的变化是连续的,徐缓的。在第二种情况下,河床质的粒径虽然变化不多,但是,通过河底沙垅的加多,却可以使曼宁糙率系数有很快的增加,这就使水流的流速降低,挟沙能力减小,河流逐渐建立起新的平衡。随着河床质的渐次粗化,河床的冲刷下切率与时俱減。野外实测结果及水槽试验成果都指出冲刷率与冲刷历时之间成一指数关系。河床质中不能为水流所挟运的颗粒所占百分比愈大,冲刷率下降得愈快,河道重新恢复平衡所需要的时间也愈短。从黄河下游的具体情况来判断,将来修建枢纽以后,下游河道在承受清水冲刷时可能作整体下降,坡降的变化不会很大。黄河下游的河床质虽然很细,同样也...
