The emission of greenhouse gases induces greenhouse effect among which CO_2 is typical. The amount of CO_2 emission from fossil fuels accounts for 80 percent of all the emission caused by human activity, and the amount of CO_2 from power plants is 30 percent.

温室效应是由于以CO_2为代表的温室气体的大量排放造成的,化石燃料燃烧产生的CO_2占人类活动引起的CO_2排放量的80%,其中电厂烟道气CO_2排放量占30%,因此电厂烟道气脱CO_2是削减温室效应的关键。

Paper introduces the present structure and features of this type of boiler in China as well as its comparison with small fossil fueled boiler in economical aspects. 电热锅炉具有重量轻、体积小、使用方便以及无污染等优点,正在广泛地应用于商业、高层建筑等许多领域中。本文介绍了我国现有电热锅炉的结构型式和特点以及它与化石燃料小锅炉的经济比 The Changjiang River is the largest in China and the third largest in the world in terms of discharge. In recent years, a number of scientists have studied on the transfer and flux of its dissolved matter. These studies are very important in illustrating the oceanographic features of the East China Sea.

In recent years, a number of scientists have studied on the transfer and flux of its dissolved matter. These studies are very important in illustrating the oceanographic features of the East China Sea. Cruise to collect water samples and surface sediments from Nanjing, lower reaches of the Changjiang River, to the estuary as shown in Fig. 1 was conducted by vessel "Venus Ⅱ" in October 1983. Pore waters of sediments were obtained by using a Model CP-1 contamination-proof hydraulic piston squeezer designed and made by ourselves. Concentrations of major dissolved constituents Na, K, Ca, Mg, Cl, SO_4 and SiO_2 in river, sea and pore waters were analyzed. Eh and pH of the waters and sediments were determined in situ. The results obtained are summarized as follows: 1. The nonanthropogenie SO_4 in the Changjiang River is attributed to weathering of sulphide and sulphate minerals, and anthropogenic sulfur which is additional source of SO_4 in this river is attributed to acid rain containing H_2SO_4 formed by atmospherical SO_2 derived from the burning of fossil fuels in the region of the lower reaches. Caand Mg in rivers are derived from weathering of carbonate minerals, Mg mainly from weathering of silicate minerals. However, Fig. 3b shows that Ca and Mg in the Changjiang River are derived probably less from weathering of silicate minerals. 2. The Changjiang River Estuary is of a characteristic two-layer flow with entrainment of sand in accordance with the salinity section of the estuary as shown in Fig. 4. Whence, a model of two-layer exchange of water between the Changjiang River Estuary and the sea can be advanced as shown in Fig. 5. In which R, Q_1 and Q_2 represent the discharges of river, outflowing upper layer water and inflowing lower layer water, C_R, C_1 and C_2 represent the concentrations of a certain constituent in river, upper and lower layer waters, respectively. Assuming a steady state and no change in water volume of the estuary, the balance between the inflowing and the outflowing as in Fig. 5 should be established: Q_1=Q_2+R (1) and in case of no addition or removal and on the basis of mass balance there should be the following relation: Q_1C_1=Q_2C_2+RC_R (2) Similarly, for a conservative constituent: Q_1C_1~0 =Q_2C_2~0+RC_R~0 (3) where C° represents the concentration of the conservative constituent Cl, the subscripts are the same as that mentioned above. In general condition such as the Changjiang River Estuary, viz, C_2~0C_R~0, and from the formula 1, 2 and 3 the following expressions can be derived: Q_1=RC_2~0/(C_2~0-C_1~0) (4) Q_1=RC_1~0/(C_2~0-C_1~0) (5) C_1_(C_1~0(C_2-C_R)/C_2~0)+C_R (6) 3. In the condition of two-layer exchange of water in estuary, C_2~0, C_2 and C_R can be considered as constants. Thus, the relation of dissolved constituent concentration C_1 to conservative constituent concentration C_1~0 is a straight line in compliance with the formula 6. Nevertheless, by comparison of the results calculated from formula 6 with those of measurement, in addition to SO_4 and K in stations of H_(14) and H_(15), which were likely to occur in processes of addition and removal, respectively, the other constituents were mainly controlled by physical mixing in the estuary (Fig. 6a—f). 4. The Q_1C_1 values for the dissolved constituents in the upper layer waters of the stations in the area of the estuary are calculated and listed in Tab. 1.本文阐明了长江下游水体中的主要溶解组分,主要是由蒸发岩和碳酸盐经化学风化作用所提供的。其中,SO_4部分由化石燃料燃烧后生成的SO_2在大气中氧化成SO_3,并随降雨生成H_2SO_4而进入河水,同时还分析了长江在入海过程中,各溶解组分的浓度受物理混合的影响以及可能发生的转移和溶出作用。 According to the energy modeling and the strategies forecast of china's economic development and population, china's energy in coming century has been calculated yearly by computer in this paper.

Because the fossil fuel resources of china are limited, more and more fossil fuel will be mainly turn to industrial chemicals, and the environmental pollution will be serious if we still use the fossil as a fuel widely. The amount of renewable energy will be increased, but its share of primary energy consumption would be cut down fron 36% to about 20% during the first half of next century and then maintain thisproportion. In this case, the nuclear energy will be developed rapidly daring the early stage of next century and will become the main energy since 2040.本文从人口和经济发展的情景设想出发,运用计算机模型对中国下世纪能源需求进行了长期预测。计算机的计算结果表明,到2050年,中国的总能耗将达到每年52.5—67.5亿吨标准煤,大约是1986年商品能源总消耗的6—8倍。虽然化石能源仍将是下世纪初期的主要能源,但化石能源的年消耗量在下世纪二十年代达到16.55—20.44亿吨标准煤后将迅速下降。这是由于可以经济开发的化石燃料资源有限,运输量大,污染严重,对地球气候影响深远,并将越来越多地转作化工原料。可再生能源将增加。但由于可经济开发的可再生能源的资源有限,因而随着总能耗的增加,它在总能耗中的份额将由下世纪初期的36％下降到下世纪中期的20％左右。下世纪初期核能将迅速发展,并可能在2040年左右超过50％而成为主要能源。&nbsp&&&&&相关查询
