We consider the thin shells of non-reinforced concrete as a membrane and show that they should be satisfied the following Poisson equationa2z/ax2+a2z/ayz=W/N,where W is the load of the shells per unit area, N is the inner tension under loading along the normal on the circumference of the shells. We solve the Dirichlet Probem for rectangular domain by means of the method of approximation, calculus of variations and the method of difference equation.

The PhYSiological effects of Pre-sowing treatment of Bailan melon Seeds with γ-rays at dosages 1, 5, 25, 75, 100, 200 and 300γ were determined. The rate of Plant growth and development was accelerated and the yield of the fruit Per unit area of land was increased bY the treatment with γ-rays at all dosages used in this exPeriment, The rate of photosyathesis was raised to as high as four times that of the control when treated with 25T. The chloroPhyll content of the leaf and the total soluble solid content of the fruit were also increased significantly by the above treatment. Dosages between 5-75γ were most effective in most cases. The gamma irradiation al so enhanced the Process of sugar accumulation of the fruit. It was found that the amount of reducing sugars was increased during the early stages of fruit growth and the amount of non-reducing sugars was increased during the ripening Period of the fruit by seed treatment. The total sugar content of mature fruit of tho treated Plants was 1.085% higher than that of the control.

1.A close relationship is existed between the proper water content of soil and the incre-ment of flowers and prevention of pod-shedding of soybeans.Number of pods borne on a single soybean plant as well as seed yield would decrease and pod-shedding rate would increaseas the plant suffered from drought during flowering and pod-bearing stage.The suffering isparticularly severe if drought occurs in late July when soybeans are on full-blooming-stage.Under such condition the growth and development of soybean plant would be hindered andless vigorous;pod-shedding rate would sharply increase while seed size would be larger.InAugust when pods are on forming-stage,drought would cause less damage on plant vigor butpod-shedding rate would be comparatively high,seed size would noticeably decrease,andpod-formation-stage 70%,and pod-filling-stage 60-65%.The experimental results of the past several years have showed that,in the leachedchernozen soil region of North East of China,the proper soil water content (in per centof water holding capacity) of the 0-5 50 cm.soil layer of the high yielding soybean field duringdifferent soybean growing stage should be:branching-stage 55-60%, blooming-stage 60-70,%,pod-forming-stage 70%,and pod-filling-stage 60-65%.2.If the density of stand and planting method are regulated according to soil fertility,number of pods per unit area would greatly increase,owing to that under such conditionsillumination and soil fertility can be fully utilized by soybean plants,and resulting in theincrement of photosynthetic rate and accumulation of photosynthetic products.Under lessfertile soil when variety Small Golden Yellow No.1 is used,and row distance is 60 cm.,thesuitable density of stand would be 250-300 thousands of plants per hectare.Under more fertileconditions the suitable density of stand should decrease to 100-150 thousands of plants perhectare.As to the method of planting,on fertile soil the 45×45 cm.square method with 3-5plants in each hill is much better than drilling method of which the distance between rows is50 cm.or 60 cm.Under square method,both of the rate of pod-bearing and the rate of pod-shedding of soybeans are high.When potato or wheat is interplanted between the rows of soybean,utilization of illumina-tion and soil fertility as well as microclimatic conditions are greatly improved.This wouldeffectively raise the number of pods of the individual soybean plants.For interplantation2:2 or 3:3 ratio is recommended for the fertile soil.3.The best time of topping (on comparatively fertile soil) of soybeans is preliminarilyconsidered to be on late blooming-stage.Topping on branching-stage is next,while on earlyblooming-stage ranks the third.Fertilizers containing NK Show the best result when theyare applied on late blooming-stage,while P fertilizer gives best result when it is applied onbranching-stage.The spraying of 3% of superphosphate solution for 2-3 times on leaves of soybeans duringthe pod-bearing stage (early August) can reduce the rate of pod-shedding.4.The spraying of minor-elements on soybean plants during full-blooming- and earlypod-forming-stage can increase intensity of respiration and photosynthetic capacity,andthus,beneficial for the increase of seed yield.The proper concentration of ammoniummolybdate solution sprayed during full-blooming-stage and early pod-forming-stage is 0.05%,while that of zinc sulphate sprayed during full-blooming-stage is 0.01%.5.Paying great attention to fieid management and adopting the practice of deep plowingare effective measures to promote soybean plants to have a vigorous growth and to bear moreflowers and pods.
