The changes of nitrogen content, free amino acid, C/N ratio and chlorophyll content of wheat in wheat-faba bean intercropping system were studied by pot experiment with 3 N levels 0, 75 and 150 mg Nkg^(-1 soil. The results showed that leaf nitrogen content of intercropped wheat was higher than that of monocultured wheat at 3N level at tilling and booting stages, but was lower at heading stages.

Author was menstruated content of boron and researched the status of lack of Boron and researched relativity of its Influencing facto, the results showed that the average content of available boron in the yellow soil was 0.39±0.27 mg/kg, 80 percent of its was under 0.5mg/kg which was lack for boron and 17.44 percent of its was under 0.2mg/kg which was especially lack for boron; The distribute frequencies of available boron contents of yellow soils in Chongqing was dispersedly, its range of 0.07mg/kg to 1.99mg/kg. The diversity of different zoology area was distinct. The result of pertinence analyses showed that available boron contents had correlativity with the pH(r=0.181** n=281) and CEC（r=0.124** n=281 and It had correlativity with Organic matte When the content of organic matte is high; in addition, soil granule、clime was the Influencing factor of availability of boron in Yellow Soils in Chongqing.

笔者通过调查取样对重庆市黄壤硼的含量进行测定并分析了缺硼的程度，对其影响因素进行了相关性分析，研究结果表明：重庆市黄壤有效硼的平均含量为0.39±0.27mg/kg，其中近80%的土壤样品有效硼含量低于0.5mg/kg，属于低硼或缺硼土壤，还有17.44%的土壤样品有效硼含量低于0.2mg/kg，属于极度缺硼的土壤；而有效硼含量的分布频率比较分散，变幅较大，从0.07mg/kg~1.99mg/kg，变异系数达到69.41%，不同生态类型区土壤有效硼含量的差异十分明显；而相关性分析结果表明：土壤有效硼与土壤pH值(r=0.181** n=281)和CEC（r=0.124** n=281呈正相关，在有机质含量较高的条件下与其相关性也较为显著（r=0.347** n=90，而土壤质地以及气候也对重庆市黄壤硼的有效性有很大的影响

The invention can lead the conversion rate of quick lime during the digestion process to reach more than 95 percent and water content in digestion products to 5-10wt percent; besides, slaked lime absorbent produced has excellent desulfurization effect for Ca2 content and water content, etc.

本发明方法可使生石灰在消化过程中其转化率达到95％以上、消化产品中的含水量为5～10wt％，制备出的熟石灰吸收剂由于Ca2含量、含水量等能控制在一个较适宜的范围内，因此其脱硫效果十分理想。

The results show that, under each drip irrigation treatment before the tasselling stage of spring maize, the fluctuation of average soil water content and soil matric potential at different soil depthes are comparative low under high frequency drip irrigation treatment, and the HDI can hold stable soil water content. The drip irrigation can obviously delay the effect of air temperature on the soil temperature, which was influenced by irrigation process, soil water content and crop growth stages. In addition, the irrigation frequency affects the spring maize root distribution in the soil, and the HDI improves the probability of root distribution in upper soil(0~40 cm). The yield difference of spring maize for irrigation frequency treatments is not significant under the typical field irrigation model combined irrigation with precipitation.

试验结果表明：在春玉米抽雄期以前阶段实施的滴灌各处理中，高频滴灌下土壤平均含水率和不同深度处的土壤基质势波动幅度较小，高频滴灌下土壤水分能保持在一个比较稳定的范围；土壤温度受灌水过程、土壤含水率及作物生育阶段的影响较明显，滴灌能显著延迟气温对土壤温度的影响；灌水频率对春玉米根系分布存在一定影响，高频灌溉能显著促进春玉米根系在上层土壤(0～40 cm)中的分布；此外，在这种典型的灌溉和降雨相结合灌溉模式下，不同灌水频率下玉米产量差异不显著。

In the toped and untoped tobacco when applied with hormone, both content of IAA and GA3 increased but others decreased in tobacco that treated with IAA and GA3; The content of ABA increased significantly but the content of IAA and GA3 decreased when applied with ABA.

打顶与不打顶喷施外源植物激素的处理中，IAA和GA_3均可使叶和根中该激素含量提高，而其他激素含量下降；喷施ABA可以使烟株体内ABA明显增加，IAA和GA_3含量下降，ZR略有增加，但增幅不大。

According to the change of the kinds of elements content in slag, F in slag volatilizes in the form of KF and NaF, KF volatilizes much more easily than NaF, KF plays a leading role in the F volatilization, theoretical analysis shows that the saturation vapour pressure of KF in the test slag is 31. 4 times of NaF; when F content is far more than K, KF volatilization is first order grade reaction, it is dominated by K content, the apparent activate energy is 275. 30KJ/mol.

4依据对含氟熔渣中高温条件下（1450℃、1505℃）的各种元素含量的变化情况，发现氟在熔渣中是以碱金属氟化物挥发，并且，KF比NaF具有更好的挥发性，在氟的挥发中占主导地位，理论研究也证明，在1505℃试验组成的熔渣中，KF的饱和蒸气压是NaF的31.4倍；在含氟量远大于钾含量的情况下，KF挥发为一级反应，受钾浓度控制，其表观活化能为275.30KJ／mol。

The results showed that the two kinds of Ni-P electroless deposits are both amorphous. The phosphorus content in the deposit using lactic acid as complexing agent is 10.04%, and in the deposit using citric acid as complexing agent is 11.93%. As the Na2S content increases, the polarizability increases, and the corrosion current and corrosion potential decrease while the Na2S content is between 1.0%~2.5%. The corrosion resistance of Ni-P electroless deposit using lactic acid as complexing agent is better than that of another kind.
