It is conducive to uptake soil nitrogen for flue-tobacco on dryland soil with maize-tobacco rotation before topping (60 days after transplanting) and uptake soil nitrogen for flue-tobacco on paddy soil with rice-tobacco rotation after topping.2 The nitrogen utilization efficiency of rapeseed cake, rice straw and rape straw were 19.5%, 15.5%, 8.1% respectively, and the inorganic fertilizer nitrogen utilization efficiency were 41.1%, 42.7% and 35.7% under the combined application of organic additives and inorganic nitrogen fertilizer. The contribution rate of rapeseed cake, rice straw, rape straw to accumulated nitrogen of flue-cured tobacco were 1.0%, 2.4%, 2.7% respectively by the combined application of organic additives and nitrogen fertilizer. Flue-cured tobacco for organic nitrogen absorption meet with the nitrogen needs laws of high-quality tobacco, indicating that the combined application organic additives and inorganic nitrogen fertilizer reduces the nicotine content of tobacco, an increase of sugar/nicotine ratio and improved the quality of tobacco. In which the role of rice and rape straw is greater than the rapeseed cake can be used as measures to lower nicotine.3 Nitrogen accumulation in flue-cured tobacco with the total nitrogen input was a significant positive correlation during the growth stage of flue-cured tobacco. The total nitrogen input for the 156.3-405.5kg.hm-2, in which the soil nitrogen mineralization capacity account for 22.6%-54.3%, with an average of 34.5%, that is, soil nitrogen mineralization accounted for 1/3 of the total nitrogen input.

旱地轮作土壤有利于烤烟生长前期对土壤氮素的吸收，水旱轮作土壤增加了烤烟生长后期对土壤氮的吸收。2在有机添加物与无机氮肥配施条件下，烤烟对有机添加物中氮的吸收规律基本符合优质烟的需氮规律，其中烤烟对菜籽饼肥、稻草秸秆、油菜秸秆所含氮素的利用率分别为19.5%、15.5%、8.1%，所配施无机氮肥的利用率分别为41.1%、42.7%和35.7%，菜籽饼肥、稻草秸秆、油菜秸秆对烤烟氮素累积量的贡献分别为1.0%、2.4%、2.7%。3不同轮作方式及添加有机物条件下氮素平衡结果显示，烤烟生长期间的氮输入总量为156.3-405.5kg.hm-2，其中矿化氮量为输入总氮量的22.6%-54.3%，平均为34.5%，约为输入总氮量的1/3；肥料氮的利用率为31.4%-42.7%；植烟土壤氮素表观损失率在37.5%-57.2%，平均为46.9%，约为输入总氮量的一半。

Any sum insured under 20.1.2 to be taken into account and only the excess thereof may be insured, which excess shall be reduced as the hire is advanced or earned under the charter by 50% of the gross amount so advanced or earned but the sum insured need not be reduced while the total of the sums insured under 20.1.2 and 20.15 does not exceed 50% of the gross hire still to be earned under the charter.

根据第20.1.2项的投保金额应予考虑，仅其超额部分可以保险，而且应从中扣除根据租船合同已预收或已赚取的总租金的50％，但如果根据第20.1.2项及第20.1.5项的总保险金额不超过根据租船合同待收总租金的50％时，可不作上述扣减。

The results showed that the change of storage region had great effects on the property and sugar content of sweet sorghum. The change of sweet sorghum stalk with total sugar content about 58%(g/g dry sweet sorghum stalk) stored in the cold and dry Sonid Right Banner was as follows: rapid water loss and rapid dryness and sugar loss as 13%. When stored in Beijing, its change was as follows: sugar loss reached up to 25% and serious mildew occurred.

结果表明，区域选择的差异，对甜高粱秸秆的贮藏产生较大的影响，总糖约58%的甜高粱秸秆在低温、干燥的苏尼特右旗全年贮藏的物性变化为：失水、干燥速度快，总糖损失为13%；北京贮藏的甜高粱秸秆总糖损失达25%，霉变现象严重。

This thesis introduces "total volume method" into VAV control schemes, and analyses its advantages.

本文在进行广泛的文献阅读的基础上，对目前采用主要变风量系统形式、变风量末端形式以及主要的系统控制方法进行了分析和对比，指出了静压控制方式的主要缺陷，进而提出了采用&总风量控制方法&对变风量空调系统进行控制，该方法不再以静压作为调节风速的参数，而是以系统当前要求的总风量来调节风机的转速，并分析了总风量控制方法的优势和特点。
