| 抄録 | Morphology and formation mechanism of poly (4'-oxy-4-biphenylcarbonyl) (POBP) crystals obtained by solution polymerization were firstly treated. It was concluded that the formation mechanism of the bundlelike aggregates of fibrillar crystals in POBP was fundamentally simillar to that in POB whiskers. Secondly the copolymerization effects of m-acetoxybenzoic acid and 4-(4-acetoxyphenyl) benzoic acid on the morphology of POB whiskers were studied. The experimental results strongly supported our proposal for the formation mechanism of whiskers which was consisted of crystallization of oligomers with a critical length as lamellae from solution and solid state polymerizationof oligomers between lamellae. Finally, the formation mechanism of poly (p-oxycinnamoyl) spherical products during solution polymerization was treated. The formation of these spherical products could be understood by overlapped phase diagram of melting depression curve and consolute curve of oligomers-solvent system. |

| 抄録 | The antigenicity of liposomes sensitized with haptenated phosphatidylethanolamine (PE) and the reactivity of the liposomes with complement depended on the length of the spacer between hapten and PE. To establish the optimal conditions for the assay, haptenated PE's with various length of spacers are required. In the previous method, hapten-spacer molecule was first synthesized to which PE was conjugated. Therefore, even different hapten molecules and different length of spacer molecules were used, every combination of hapten and spacer has to be synthesized. A new procedure for preparing hapten-spacer-PE was described here. We first prepared conjugates between PE and various length of spacer molecule, the terminal of which is an amino residue. These molecules react well with activated hapten molecules, giving a good yield of hapten-spacer-PE. |

| 抄録 | The drop formation in immiscible liquid-liquid systems under mass transfer conditions was experimentally investigated. To know the exact effact effect of mass transfer on drop sizes, the decrease of interfacial tensions due to the presence of solutes has to be evaluate. Interfacial tensions of liquid pairs were measured with a Wilhelmy method as a function of the relative amounts at which both the solution and the solvent were mutually saturated. The interfacial tensions between the liquid pairs mutually saturated at on equal amount were found to be appropriate for the prediction of the drop formation accompanying mass transfer. |

| 抄録 | An alumina-zirconia (AZ) composite powder was prepared by thermal decomposition of the organic precursors, which were synthesized from ethyl acetoacetate aluminium diisopropylate and zirconium n-butoxide. Specific surface area of AZ was higher than that of alumina-zirconia (ALK) prepared from aluminium sec-butoxide and zirconium nbutoxide. True density of AZ was lower than that of ALK. Selective reduction of nitrogen oxide with propylene in oxygen-rich atmosphere on AZ was superior to that on ALK. |

| 抄録 | This paper presents a new method for prediction of consolidation settlements of soft grounds. The method is based on the theoretical result which shows that the settlement velocity of soft grounds non-improved or improved with sand drains decreases exponentially with time. Final settlements can be easily derived from the regression analysis for the relationship between the elapsed time and the observed settlement velocity. The method has advantages of its simplicity and capability to give the satisfactorily good estimate of the consolidation settlements, and also the support of the theoretical background. |

| 抄録 | This paper describes the prediction of seepage in the impervious zones of six embankment dams by seepage analysis. In addition, by making use of the available monitored pore water pressure data of the first filling of reservoir, back analysis was carried out to estimate the best fit seepage parameters. The estimated parameters were used for further prediction of pore water pressures in subsequent monitored durations with reasonable accuracy. The accuracy of prediction was evaluated quantitatively by the prediction difference and error index. The results show that the error indices in the upstream sides of the impervious zones are smaller than those in the downstream sides. |

| 抄録 | The SWAP93 model was used to predict how much capillary rise would occur in cropped fields. The experimental fields were located in a humid climate and it was thought that contribution from groundwater sources to total water use could be significant. In one field planted with soybean, the model predicted an average daily uptake of 1.3 mm; in another field planted with pumpkin, there was average daily uptake of 0.3 mm; and yet in a third field located in a vinyl house there was average daily uptake of 0.03 mm. These predictions represent about 38,7 and 1% contribution to total water use respectively. Even though there were no measured data to compare with, the results lie within the range of other works reported in the literature. |

| タイトル（別表記） | Process of Acid Sulfate Soil Formation from the Viewpoint of Moisture Conditions on Coastal Muddy Soil and a trial of it's Amelioration |
| フルテキストURL | 001_135_141.pdf |

| 抄録 | According to recent soil survey data, it has been reported that acid sulfate soils cover areas of about 11,670,000 hectares all over the world and about 40% of those are in South-East Asia. Most of crops could not be grown on those areas without any amelioration due to low soil pH. This report consists of two parts. One is on acid sulfate soil formation in laboratory experiment. Another is on a trial of acid sulfate soil amelioration in field experiment. The results obtained on acid sulfate soil formation, in order to make clear the relationships between the process of oxidation of sulfur compounds and the moisture conditions (moisture suction) in coastal muddy soils, in laboratory experiment are summarized as follows; The concentration of sulfuric ions increase as oxidation of sulfur compounds contained in pyrite, etc. occurs, and as a consequence, the soil pH decreases in the coastal muddy soil (Fig.1). Especially, the soil pH decreased remarkably in the range of pF 2.3~3.4. The activity of soil microorganism takes part in this reaction by helping out with bringing about sulfur oxidation and formation of sulfuric ions. The pH decrease in the soil with autoclaved treatment was only slight at pF values lower than pF 3.0. Accordingly, it is concluded that the decrease of pH in coastal muddy soil occurred mainly due to soil microorganisms which oxidize sulfur compounds under the condition of higher-water than pF 3.0. The results of field experiment is summarized as follows; As a general rule, it is able to remedy the surface acidification of peat/acid sulfate soils by mixing lime dust with plough layer. However, the effect of mixed lime dust is easily disappeared in the area where the acidic ground water table is always high and moves up over the surface in rainy season. Therefore, it was carried out that several experiments for seeking protection against surface acidification due to capillary upward movement of acidic ground water by means of inserting a buffering layer of lime gravel (thickness of lime gravel layer =5㎝) between the top soil and the acidic subsoil (20 ㎝ depth) in the fields, Munoh series which is young acid sulfate soil, at the Narathiwat Land Development Center in South Thailand. The results of soil pH measurement carried out in the field in November of 1985, August of 1987 and September of 1990, it coincides with 2,4 and 7 years respectively after the beginning of the experiments, are shown in Table 3. In the plot of P2 and U1, application of lime dust to the plough layer can increase soil pH rapidly but it's residual effect is not so long. Within a 5 year period, the soil pH is likely to return to below 4. On the other hand, an underlaid lime gravel layer tends to improve the soil around the lime gravel only slight but steadily with time. Therefore, it is concluded that surface soil acidification caused by the upward movement of acidified ground water would be protected against, rapidly and continuously, by both mixing lime dust with plough layer and underlying lime gravel below plough layer. If acid sulfate soil areas would be used as upland fields, much of organic matters in soil are easily decomposed by drying. Therefore, it is suggested that it would be better for these areas to be used as paddy fields, also from the above results. |

| 著者 | 三浦 健志| |
| 抄録 | In this paper, secular changes of air temperature and the amount of precipitation in Okayama city are discussed using observed values at Okayama meteorologiccal station. Special reference is made to 1993 and 1994 in which peculiar changes occurred. The results obtained are summarized as follows: (1) The increasing rate of the annual mean air temperature at Okayama city is 0.85℃/100y. This value is nearly equal to the average of Japan; 0.87℃/100y. (2) The increasing rate indicates seasonal changes, and the rate is high especially in April and May. (3) The rapid increase of the air temperature in the 1980s is due to removal of Okayama meteorological station from the edge of town to the center. (4) The annual mean air temperature in 1994 is 16.9℃, and the monthly mean temperature for July and August are 29.8 and 29.6℃ respectively. These values are new records at the Okayama station. (5) The air temperature in July and August, 1993 are higher than in 1980 when it was much colder in the summer. (6) The amount of precipitation does not show any secular changes. |

| 抄録 | Actual irrigation situation in a typical upland irrigation district was estimated by the water balance method during the 1993 rainy and the 1994 dry year periods. Soil moisture conditions were analysed for cases where daily district water use was supplied to all the cropped upland farms, and to reduced irrigation area percentages. Consumptive use was obtained through monthly weighted crop coefficients used to reduce penman's potential evapotranspiration. The moisture budget was examined at three levels of total readily available moisture, TRAM, i.e., 20,30 and 40 mm; the effect of upward capillary rise was also considered. The results of this study indicated that the actual moisture conditions in upland irrigated farms is influenced by irrigation area, cropping pattern, stage of crop growth and upward capillary rise in the farms. Actual irrigated area was within the range of about 44 to 100% of cropped area while upward capillary rise was between 0.1 and 1 mm day-1, TRAM level of 30 to 40 mm was considered most appropriate for the district. Monthly effective rainfall percentages from the water balance method were fairly close to that determined by the basic irrigation requirement method for some months. Basic irrigation requirement may therefore be considered to incorporate capillary water contribution. |
