The update model of the probability vector in compact GA is characterized by random walk, based on which the components update of the probability vector in the CGA with binary code is studied. A novel algorithm is proposed consequently. By using this algorithm, the fitness difference of the two competitors is increased. This can guarantee the probability vector updates availably.

紧致遗传算法中概率向量进化的模型是随机游动模型，据此研究了二进制编码中向量分量的进化特性，提出了分级竞争紧致遗传算法（grading competition compact genetic algorithm，GCCGA），加大参与竞争的两个个体的适应度的差距，使概率向量有效进化。

Processors analyze and monitor seismic frequencies in order to select proper time and frequency parameters in data processing.

在地震勘探过程中，多种因素影响地震波频率的变化，在数据处理过程中分析和监控各种波场的频率属性能够使处理人员了解数据频率成分的变化规律，有针对性地选择处理中的空变参数和频变参数。F-X-Y谱估计方法在三维空间上统计有效波的频率，结果较准确，对问题的分析更加细致。

The principle of proportionality may effectively limit the implementing of national public power and coordinate public interest and private interest by weighing benefits. The principle has broken the absolute concept of the private interest's superiority or the public interest's superiority and put the two interests into the concrete situation for analyzing.

比例原则可以有效地限制国家公权力的行使，最大限度地保护公民私权利，并且通过利益衡量的方法，在公共利益与私人利益之间进行协调，打破了私人利益至上和公共利益至上的绝对观，从而使二者处于具体情境中待分析的状态，没有哪个处于绝对优先的地位。

Following are summary of our works:(1)The powders of LaCr_(0.9)Co_(0.1)O_3, LaCr_(0.9)Fe_(0.1)O_3, LaCr_(0.9)Ni_(0.1)O_3, LaCr_(0.95)Sn_(0.05)O_3 and LaCr_(1-x)Ti_xO_3(x=0.0-0.3) were single perovskite phase with orthorhombic structure. The gas-sensing properties of their thick film sensors were tested in the acetone, ethanol, normal propyl alcohol, carbinol and formaldehyde organic gases. The sensitivity of the sensors can not be enhanced effectively by doping Co、Fe、Ni、Sn elements in B-site of LaCrO_3. Ti dopant with proper concentration can greatly improve the gas-sensing properties, which make the sensor display higher sensitivity and quicker response-recovery characteristics.

所得结果摘要如下：(1)LaCr_(0.9)Co_(0.1)O_3、LaCr_(0.9)Fe_(0.1)O_3、LaCr_(0.9)Ni_(0.1)O_3、LaCr_(0.95)Sn_(0.05)O_3和LaCr_(1-x)Ti_xO(来源：ABfd1dC论文网www.abclunwen.com)_3(x=0.0-0.3)粉体为正交单相钙钛矿结构，其厚膜型气敏元件在350℃时对丙酮、乙醇、正丙醇、甲醇、甲醛等有机气体的气敏性能测试表明：0.1mol Co、Fe、Ni和0.05mol Sn元素在LaCrO_3的B位进行掺杂后，不能有效提高材料对以上测试气体的气敏性能；而Ti元素的适量掺杂可以极大地改善LaCrO_3的气敏性能，使之显示出对丙酮气体的高灵敏度和快速响应恢复能力。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
