| | The general configuration of geographical features of the He-xi Gallery is unrivalled in the world. Three great mountains form a "Venturi tube" , the prevailing west wind in high-altitude causes a "strong region" at the throttle-E. long. 95°-105°, N. lat.40°-45°. An-xi county, world-famous "wind Storehouse" , possesses an annual averge wind speed greater than 3.5 meter per second.The He-xi Gallery is a dry semi-desert among the north temperate zone, possessing abundant solar energy: sunshine time, 3360 hr./... | | 河西走廊的地貌是举世无双的。三条大山脉在东径95°~105°,北纬40~45°之间形成“纹杜里管”的喉部,高空盛行西风在此处产生一个“强区”。安西县是世界闻名的风库,年平均风速大于3.5米/秒。 河西走廊属于北温带干旱区,太阳能丰富,日照为3360小时/年,垂直辐射量为150310~163370卡/厘米~2/年,相当于太阳常数的76%。 综合利用风能和太阳能资源发电,提供动力,开发地下水以资灌溉。促进畜牧、工、农业生产是极有前途的。 | | 文摘来源 | | Added 0.3% (NH4)2HCO3 into the rotted straw can advance the biogas yield of rural biogas digester significantly, during anaerobic digestion process. In comparision with the rotted straw in which added pig and cow manure, the biogas yield can increace 100%.In order to settle for the barren nitrogen in rural biogas digester, (NH4)2HCO3 can replace the human and animal wastes to obtain higher efficiency of biogas production.Added 3 kg (NH4)2HCO3 into rotted straw, per cubicmeter volume digester can produ... | | 把0.3%的碳酸氢铵添加到堆沤过的谷草内,在厌氧消化过程中可显著提高沼气池的产气量。与已堆沤过的谷草加猪、牛粪比较,产气量提高100%。用碳酸氢氨代替人、畜粪便可获得较高的产气率,每立方米沼气池加入3公斤碳酸氢铵可产沼气14.1立方米。在沼气发酵过程中,碳酸氢铵的肥效可得到保存,并导致有机肥和无机肥自然结合施用。 | | 文摘来源 | | A method for the rapid determination of boron in seawater using fluoroborate ion selective electrode is developed. Boron convert into BF4~ with concentrated hydrofluoric acid in advance. Measurement with the BFr-ISE oan be carried out in pH 4. Ca2+, Cl~, Br~ and I- in seawater do not interfere with determination of boron. Some samples have been analysed by this method with satisfactory results, | | 建立了用氟硼酸根离子选择电极快速测定海水中硼的方法。预先用浓氢氟酸将硼转化成氟硼酸根,然后在pH4用氟硼酸根离子选择电极进行测量。样品中的Ca~(2+),Cl~-,Br~-和I~-不干扰硼的测定。用本法对某些样品进行分析获得满意的结果。 | | 文摘来源 | |   | | << 更多相关文摘 |
