The results indicated that organic fertilizer at a rate of 75000 kg/ha or organic fertilizer (75000 kg/ha) with compound fertilizer at a rate of 300 kg/ha had higher effects on genetic diversity of soil microbial community under field conditions. Treatment of fertilizers as base application at level of 600 kg/ha resulted in decrease of DNA sequence richness index and diversity index of soil microbial communities, and the similarity coefficient of DNA sequence from soil microbial communities was the lowest compared with control. Organic fertilizer treatment was conducive to increasing DNA sequence diversity index and evenness index of soil microbial communities.

The invention refers to a method to correct universal frequency of electric communication technique, its character: make signal index quantization on the complex number of cross product, to directly reflect the quantized numerical value of tangent value and the located quadrant of imaginary and real parts, use inverse tangent ROM table to discriminate the processed result, then make loop filter and phase accumulation on the discriminated result to obtain error-correcting angle, and use digital controlled oscillator to make table look-up and quadrant adjustment to obtain correcting factor; use the relationship of trigonometric function in each quadrant to compress inverse tangent look-up table ROM and digital controlled oscillator look-up table ROM.

一种涉及电通信技术的通用频率纠正的方法，其特征在于：它采用如下步骤：经过叉积的复数进行信号指数量化处理，通过该复数虚、实部信号的指数量化结果的差值及其极性直接反映虚、实部的正切值的量化数值以及所处象限，将处理后的结果通过反正切ROM表进行鉴频，鉴频后的结果经环路滤波和相位累加，得纠偏角度，通过数控振荡器针对纠偏角度进行查表和象限调整，得到纠正因子；通过个象限之间的三角函数关系来压缩反正切查表ROM和数控振荡器查表ROM的大小，本发明资源耗费小，效率高，可极大地节省内存资源。

by calculating the rca of guangxi in recent years and its ntr index of 2006, the author comes to the conclusion: compared to other provinces in china, the superior industries of guangxi are mainly labor intensive industry and resource intensive industry; and food manufacturing industry, chemical industry and paper making industry are increasingly developing, which have become the new advantages in export; electromechanical products and hi-tech products of guangxi are inferior to those of other provinces in china.

文章计算了广西近几年的显性比较优势指数和2006年贸易竞争力指数，通过综合分析得出广西出口产业的比较优势格局：广西相对于全国具有比较优势的产业主要集中在资源密集型和劳动密集型产业，且部分产业的优势地位趋于减弱；近年广西重点发展的食品制造、化工、造纸等产业发展较快，已成为在全国具有强比较优势的出口产品；机电产品和高新技术产业处于明显的比较劣势地位。

objective to determine the menarche age among female students and the relation between body fat and menarche in anhui province to provide theoretical basis for adopting intervention measure and carrying out health education.methods probability unit regression were used to calculate mmas in 3 000 girls aged 9～18 years old,who were selected from 3 areas in 2005.results mmas were 12.76 and 13.11 years old for urban and rural girls respectively.the youngest age was 10.the menarche age was significantly,related with bmi sebum thickness of abdomen,sebum thickness of shoulder blade and the upper arm.conclusion there was significant relationship between menarche age and body fat.menarche age showed an ahead trend in han national students in anhui province.sex eduction should be conducted in advance,and it was important to strengthen sex education in adolescent.

目的 了解安徽省女生月经初潮及初潮前后体脂变化情况，为采取干预措施和健康教育提供理论依据。方法按照2005年全国学生体质调研要求，采用分层整群抽样方法，对安徽省南、中、北3个地区城乡9～18岁中小学女生3000人进行调查，并测量体质指数、腹部皮脂厚度、上臂皮脂厚度和肩胛下皮脂厚度4项指标。结果城市女生半数月经初潮平均年龄为12.76岁，农村女生13.11岁，城乡最小月经初潮年龄均为10岁。体质指数、腹部皮脂厚度、上臂皮脂厚度和肩胛下皮脂厚度4项指标均值来潮组均大于未来潮组，差异有统计学意义，p.01。结论月经初潮年龄与体脂因素关系密切；安徽省汉族学生月经初潮年龄呈现提前趋势，性教育应提前，加强青春期性教育尤为重要。
