    In this paper the general synthesis problem of optimal control systems with the criterion of transient responses as a positive integral functional (3) is discussed.In the first part it is assumed that the motion of controlled object is described by a system of ordinary differential equations and that the final states of the system form a bounded and closed convex region in n-dimentional euclidian phase space. A method is proposed for finding all optimal control functions which lead any starting state into the given final region of states. Some conclusions are obtained from the maximum principle by using transversal conditions of optimal trajectories in terminal points, and the particular properties of the stated problem are pointed out. The case of linear dif-ferential equations with integral quadratic functional criterion is investigated in detail.Further, in the second part the fundamental properties of isoloss regions, the rela-tions between the isoloss region and optimal control functions are indicated. As a direct result a partial differential equation determining the optimal loss-function J (x) is found and the connection between function J (x)and optimal vector control function u (x) is also stated. The methods proposed are practically the extension of the me-thods used by us for designing time optimal control systems as seen in [5, 6 ,7].Finally, an example is illustrated with optimal trajectories shown in phase plane.The necessary numerical data is calculated by an analog computer with high accuracy.

    In phosphate buffer the optimal pH for the activity of the particle-bound CoIH cytochrome c reductase system of heart muscle preparation is between pH 7 and 8, whereas in glycylglycine buffer it is pH 8.0. The activity of this enzyme system in the latter buffer is considerably lower than that in the former (Fig. 1).

    In phosphate buffer the optimal pH for the activity of the particle-bound CoIH cytochrome c reductase system of heart muscle preparation is between pH 7 and 8, whereas in glycylglycine buffer it is pH 8.0. The activity of this enzyme system in the latter buffer is considerably lower than that in the former (Fig. 1). Addition of ethylenediamine tetraacetic acid caused considerable stimulation of its activity in glycylglycine buffer, indicating that the lowered activity in the latter buffer is probably due to disturbance in the physical state of the enzyme preparation. The optimal pH for the particle-bound CoIH cytochrome c reductase system of heart muscle preparation, whether in phosphate or in glycylglycine buffer, differs markedly from the value of 8.7 reported by Mahler et al for their soluble CoIH cytochrome e reductase in glycylglycine buffer. It has been found that addition of a relatively large amount of the soluble CoIH cytochrome c reductase to heart muscle preparation does not result in any increase in activity of the CoIH oxidase system. The amount of soluble CoIH cytochrome c reductase added had an activity about 8 times that of the reductase system already present. The addition of this amount of the soluble enzyme also fails to restore to any appreciable extent the CoIH oxidase activity of heart muscle preparations previously treated with 2,3-dimercaptopropanol. It is known that 2, 3-dimercaptopropanol treatment does not affect cytochrome c or cytochrome oxidase. These show that the soluble CoIH cytochrome c reductase of IV[abler et al reacts only with soluble cytochrome c but not with the cytochrome c firmly bound to the particulate matter of enzyme preparations. The cytochrome c reductase activity of the Keilin-Hartree heart muscle preparation can be easily extracted by 9% alcohol at pH 5.4 using the procedure of Mahler et al. However even when the CoIH cytochrome c reductase activity of the heart muscle preparation has been completely destroyed by 2, 3-dimercaptopropanol treatment, the alcohol extract still contains the soluble reductase with an activity comparable to that extracted from an untreated control (Table 5). This seems to indicate that the soluble reductase of Mahler et al is formed during the extraction procedure and is therefore different from the enzyme originally present in the heart muscle preparation. The evidence presented above together with those previously obtained by us and by other workers all point to the conclusion that the soluble reductase of Mahler et al is an artifact.

    The present report deals with the results of some studies on the longevity of the soft-rot organism, Erwinia aroideae (Towns.) Holland in soil. It is found that when the bacteria are added into a mass of non-sterile field soil in a test-tube and incubated at 28℃, they can not live longer than 14 days. This result is somewhat contradictory to those of Patel, but agrees with those of Gorlenko and Voronkeviz. A study of the number of microorganisms which, are able to be plated out in beef bouillon peptone agar reveals that when a known number of soft-rot bacteria is added into a soil sample, the total number of the indigenous microorganisms is increased, while the number of the introduced bacteria is rapidly decreased. After 72 hours, the total number of the indigenous microorganisms in the soil sample begins to decrease and finally reaches its original level. It is inferred that following the addition of the soft-rot organism into a soil sample, a biological equilibrium is broken and the indigenous microorganisms are stimulated to multiply rapidly. After a brief period of such an unusual multiplication of the indigenous microorganisms, the invaders are suppressed and a new equilibrium is finally established. Henceforth the number level of the indigenous microorganisms in the soil sample returns to the orginal. When the soft-rot bacteria are introduced into the soil in soil tanks regulated at different soil temperatures (and in each tank two plants of the Chinese cabbage are planted), the introduced bacteria live 11 days at 35℃, 21 days at 10℃ and 7 days at 20℃. Possibly a soil temperature at 20℃ might be close to the optimal for the activities of some antagonists of the soft-rot bacteria. When a soil sample is fertilized with the "de-oiled soybean-seed-cake" or with the "dried night soil", the elimination of the intruding bacteria is accelerated. In the plot where the de-oiled soybeanseed-cake" is applied, the soft-rot organism disappears within 24 hours, whereas in the plot of the "dried night soil", the intruding bacteria disappear within 5 days. The soft-rot bacteria in an autoclaved field soil sample live 96 days. When a quantity of manure or compost is added to the soil sample and chert autoclaved', the soft-rot bacteria introduced at such a condition live longer than 180 days. Evidently the added manure or compost in sterile condition serves as food material for the soft-rot organism.

    白菜軟腐細菌(Erwinia aroideae)在不灭菌的土壤中可以存活11天至14天。土壤中的微生物总数(指可以在牛肉汁(月柬)培养基上发育的微生物)因軟腐細菌的加入而起剧烈的波动。当軟腐細菌进入土壤中后24小时,軟腐細菌的数量銳减而土壤中的其他微生物数量上昇,以后亦逐漸递減。当軟腐細菌在土壤中消失时,土壤微生物的数量又趋于平稳。軟腐細菌在栽有白菜的土壤中,土壤温度影响其存活期:土温在35℃时可以存活11天,在10℃可以存活21天,在20℃时可以活7天。豆餅及大粪干施入土壤中时可以促进軟腐細菌的消灭。施豆餅区(豆餅微粒与土壤拌匀)在24小时中软腐細菌即已消灭,而在施大粪干区軟腐細菌可以存活5天。軟腐細菌在灭菌的土壤中可以活96天,如果施以灭菌的堆肥或厩肥时,可以延长至180天以上。
