In this paper, major agronomic traits and grain quality traits affecting rice yield and grain quality were investigated in seven aromatic rice maintainer lines bred in Sichuan and one variety introduced from America. It was aimed at estimating the numbers of gene controlling aroma, the allelism of aroma genes, location of aroma gene on the chromosome, and molecular tagging of aroma gene.

本研究利用四川新育成的七个香稻保持系(D香1B、D香2B、内香2B、内香4B、绵香2B、绵香3B、宜香1B)、一个香稻引进改良品种(泸香90)和一个非香型保持系为材料，研究了香稻保持系主要农艺性状和品质性状对品质、产量的影响，并且通过杂交群体构建对香稻香味性状进行了遗传分析。

第十八条在建设和生产过程中损毁水土保持设施的单位或个人，应按下列规定向水土保持行政主管部门缴纳水土保持设施补偿费

Soil and Water Conservation received from the administrative department in charge of soil and water conservation programs report within thirty days from the date, soil and water conservation program reports, fifteen days from the date of the decision to approve or disapprove, and written notice declare unit or individual.

水土保持行政主管部门自接到水土保持方案报告书之日起三十日内、水土保持方案报告表之日起十五日内决定批准或不批准，并以书面形式通知申报单位或个人。

In this algorithm, first, a crowed comparison operator is used to sort and select individuals according to the characteristics of multi-objective optimization. Then, a non-uniform mutation operator is applied to the observation populations to preserve the convergency of the solutions and to improve the precision of local search. Finally, a diversity-preserving operator is employed to delete the observation populations for the purpose of preserving the solution diversity.

首先，根据多目标优化特点，使用多目标密度比较算子对量子种群进行排序和筛选；然后，应用非均匀变异算子对观测种群进行变异以保持解的收敛性并提高局部搜索的能力；最后，使用多样性保持算子对观测种群进行删减以保持解的多样性。

Except that the specifications of the single-objective real-valued quantum-inspired evolutionary algorithm are kept, the proposed algorithm has three main features to enhance the RQIEA. First, the crowed comparison operator is used to sort and select individuals in multi-objective sense. Second, the non-uniform mutation operator is applied to improve the precision for local search and to preserve the convergency for the solutions. Third, the diversity preserve operator is proposed to maintain the diversity.

该算法除保留求解单目标优化问题的实值量子演化算法的特点外，还有三个主要特征：首先，根据多目标优化特点，使用多目标密度比较算子对种群进行排序和筛选；其次，应用非均匀变异算子保持解的收敛性和提高局部搜索能力；再次，使用多样性保持算子来保持解的多样性。

Gross conformation changes of the enzyme molecule as a whole require the highest denaturant concentration.

说明酶活性的表现不仅要求各种底物和效应剂的结合位点保持其天然构象，而且还要求各个位点间保持正确的空间关系，即要求整个活性区域保持其完整性。

There are many reports about analysis of isozymes between male sterile lines and their maintainers, but different crops or varieties in same crop expressed dissimilarly. There were few reports about comparison study of isozymes between male sterile line in cabbage and its maintainer at present. Most reports about analysis of isozymes between male sterile lines and their mainainter were limited 1-2 isozymes.

有关细胞质雄性不育系及其保持系花药同工酶分析的报道已有相当多，但不同作物表现不一样，同一作物不同品种表现也有差异，而且目前有关甘蓝雄性不育系和保持系同工酶比较研究的报道极少，有关细胞质雄性不育系与保持系的同工酶分析的报道多限于1—2种酶。

Capable of Mach 2.35, it has variable sweep wings which can be set to 16 degrees of sweep during takeoff and landing, 72 degrees for high speed flight, and 45 degrees for mid-range operation; the dogtooth you can see in the outer wing section fits in to the inner wing section when in the 16 degree position.

他能够达到2.35马赫，拥有可变后掠翼，在起飞和降落的时候保持16度，高速飞行保持72度，中距离任务保持45度。外部的机翼尖端在16度时恰好能嵌入机翼内段。

The 19th article in the construction and production process of soil erosion caused by not govern, unable to control their own or take soil and water conservation program approved by the management of the unit or individual, should be assessed on its soil and water conservation program or a plan to control the cost of staging the Soil and water administration departments to pay fees to combat the loss of buried by soil and water conservation administrative department in charge of management of the organization.
