The rate-determining step tor the evolution of oxygen on the PhO2 electrode in NaOH solution has been found to be the delayed discharge of OH, i.e. OH→OH+e-. The behavior of such an electrode ia the presence of multivalcnt or surface-active ions has been briefly discussed.

The present paper reports studies on the relative rate of decomposition of nine different oil cake-meals [soybean, peanut, sesame, rape seed, cotton seed(with and without hull), chinese tallow seed (with and without hull)]. In the course of decomposition of the different oil cake-meals, freguent measurement were made of the quantity of evolved CO_2 gas, and amount of the NH_4~+, NO_3~-, and NO_2~- nitrogen formed at the given intervals of the day.

The present paper reports studies on the relative rate of decomposition of nine different oil cake-meals [soybean, peanut, sesame, rape seed, cotton seed(with and without hull), chinese tallow seed (with and without hull)]. In the course of decomposition of the different oil cake-meals, freguent measurement were made of the quantity of evolved CO_2 gas, and amount of the NH_4~+, NO_3~-, and NO_2~- nitrogen formed at the given intervals of the day. These measurement served as indices of the intensity of decomposition and rate of ammonification and nitrification of the oil cake-meals that may be occur in the soil. These studies were performed in the laboratory, under room temperature condition of the summer season. All cakes were ground into meals to such particle size as to pass through a 20-mesh sieve. The cake-meals were separately mixed with cultivation soil in the proportion of one part of cake-meal to hundred parts by weight of soil. The soil used was of alluvial origin, low in organic matter and somewhat sandy in texture. It was found that decomposition of the cake-meals began soon after their application to the soil. The daily evolution of CO_2 reached its maximum for about one week. Immediately after that, the daily evolution of CO_2 declined rapidly to a such lower level and attained a rather steady declining rate after about two weeks. The trends were common in character irrespective of the kind of the cake-meals. Among the organic constituents of tile cake-meals that underwent into decomposition in the early days, nitrogeneous organic compou ads seemed to be of major importance. The production of ammonium compounds as a result of ammonification followed a trend similar to that shown by the evolution of CO_2. The maximum rate of ammonification was noticed sometime before the evolution of Co_2 had reached a maximum. The positive correlation existing between the total nitrogen content of the oil cakes and the rate of ammonification was evident. Other factors, however seemed to be also affecting the status of transformation of Nitrogen compounds. Nitrate compounds began to appear soon after ammonification had proceeded to an appreciable degree. In the course of decomposition their accumulation in the soil increased steadily with the time. Small amounts of nitrites were found under the experiment conditions which were characterized by low moisture content (25%) of the soil and meal mixtures. From the quantity of the total available nitrogen accumulated at different intervals in the course of decomposition as in the case here given, it seemed that some nitrogen might be lost through volatilization of ammonium compounds, since the soil was alkaline in reaction (the soil here used had a PH value of 7.2) Soaking the cake meals with water, lime-water, or straw-ash extract as sometimes practiced by the local farmers in some districts in Chekiang province brought about the effect of hastening ammonification and nitrification processes. But, gain in readiness of availability of the meals by this hastening effect might not compensate for the loss in total amount of available nitrogen formed. The loss was particularly evident when the cake-meals were pretreated with lime-water or straw-ash extract. It is believed that the alkaline reaction of the treated cake-meals accounts for this loss. The relative readiness of decomposition of the different oil cake-meals followed in descending order: soybean, sesame, peanut, Cotton seed (without hulls)>Cotton seed (with hulls), rape seed>Chinese tallow seed (with and without bulls). Similarly, the relative total amount of available nitrogen (including ammonium and nitrate nitrogen) formed during decomposition shows in the following order: soybean, peanut, sesame, chiness tallow seed(without hulls)>Cotton seed (with and without hulls)>rape seeds>Chiness tallow seed (with hlls).

研究了浙江省施用的九种主要餅肥在土壤中分解的情况,各种餅肥都經磨碎,并通过20孔篩。实驗証明,在夏天的温度下,餅肥施入土壤后即迅速分解,它的分解最盛时期是在一星期左右,此后即迅速下降,到二星期后,即漸趋穩定。餅肥施入土壤后,铵态氮的大量發生是在一星期以內,此后即迅速降低,轉化成硝酸态氮。硝酸态氮在一星期到二星期的时間内开始大量發生,到二星期后就漸趋穩定。土壤中有效态氮总量在各个形态轉化的过程中,有顯著的減少趋势。餅肥在施入土壤前用石灰、草灰或水处理一星期,可提早土壤中有效氮的發生,其中單用水处理的效果尤其好。实驗証明,用石灰或草灰处理餅肥,使有效态氮大量損失,而用水处理則沒有这种情况。在本实驗的条件下,各种餅肥的分解速率依次为:豆餅、芝麻餅、花生餅、棉仁餅>棉籽餅、生菜餅、熟菜餅>桕餅、青餅。各种餅肥中氮素化合物转化后所產生的有效态氮总量依次为:豆餅、花生餅、芝麻餅、青餅>棉仁餅、生菜餅、棉籽餅>熟菜餅>桕餅。

Weather forecasting is formulated as an initial value problem in the workof numerical forecasting,while in the routine forecasting in the conventionalway it is formulated as an ‘evolution’ problem of weather process,especiallythat on certain specific level.It is shown in this paper that for large-scalemotion these two different formulations are in fact equivalent under certaintrivial conditions.It is also pointed out that for large-scale motion the three-dimensional structure of the baroclinic atmosphere at certain moment isreflected in and could be reconstructed from the evolution of the contour andtemperature fields at certain level before and after that moment.

天气数值预报研究中对预报问题的提法与日常天气预报工作中由天气历史演变来作预报的那种提法是很不相同的.本文对大尺度运动讨论了这两种提法在一定的简单附加条件下是等值的.由此也说明地面温压场的演变反映了也蕴含了斜压大气三维温压场的构造,并且决定了斜压大气三维温压场的发展.
