The Cobden turbine was far less complex and far less expensive to manufacture than a typical high speed power generation turbine, but it was also far less efficient.

这种科布登涡轮机在制造方面远不及—般的高速发电涡轮机复杂和昂贵，但是它的效率也差很多。

However, the growth of the cage aquaculture of Cobia is slow in the past which can be ascribed to the lacking of efficient manufacturer - retailer channel. In addition, the self benefit-based initiation results in a deficiency of cooperation between different members of the supply chain and market access has not established leading to the increase of cost as well as the lowering of profit of supplier. Consumers also cannot obtain the products with a reasonable price.

然而，以往海鲡鱼箱网养殖产业发展一直无法有效突破，影响的因素，不是养殖技术的问题，主要是产销通路的问题，同时现行产销供应链中各层级业者皆以追求自身的利益为出发点，缺乏上、中、下游的合作关系，再加上长期未能建构有效的市场通路造成成本增加，使生产者无法获得应有之利润，消费者亦无法享受到合理的价格。

This paper proposes an efficient codebook design algorithm for image compression.

提出了一种高效的矢量量化码將设计算法。

Octavia had never been able to decide whether the codger was an efficient worker or just anxious to get rid of any visitors so he could go back to his solitude.

Octavia 一直没法搞清楚，这个古怪的老头到底是个能干的工人还是只想着快点打发走前来光顾的人好继续一个人独处。

Simple sequence repeats,alternatively called microsatellites,are regarded as useful and efficient markers for map construction of cotton,which are abundant,locus-specific,often codominant and multiallelic.

在众多的分子标记中，SSR标记具有分布广泛、位点特异性、共显性、信息量高等优点，是构建棉花遗传连锁图谱最有优势的标记。

The original data used were 5 in 12 RFLPs of a mouse F2 population including333 individuals presented in the software MAPMAKER.Classical and successive x2 testswere used to check segregation distortions of the codominant markers. And the resultexhibited that successive x2 tests was more efficient.

以MAPMAKER中提供的老鼠F2群体中333个体12个RFLP标记中的5个连锁标记为原始数据，用传统x2检测和连续x2检测两种方法处理共显性分子标记数据，比较它们对偏分离情况分析的能力，发现连续x2检测比传统的x2检测更加准确有效。

The friction performances of carbon face were investigated with an inertia friction tester. The torque curve of carbon face was ideal, the coefficient of static friction was lower than that of dynamic in 0.28 MPa, the friction coefficient of static and dynamic decreased with the braking pressure increasing. To the fiber face, the coefficient of dynamic friction of carbon face was more stable in cycle braking process, the wear rate was lower, and it was efficient to protect the couple plate not to be worn.

结果表明：碳质层的摩擦力矩在制动初期上升较快，中间过渡区平稳，尾部翘起较小；在制动压力小于0.28 MPa时静摩擦系数小于动摩擦系数，且动、静摩擦系数均随制动压力增加而减小；相对纤维层而言，采用碳质层摩擦时摩擦力矩曲线形态更好，连续制动时摩擦系数波动较小，磨损率低且能够有效保护偶件，是1种静/动摩擦系数比较低且适用于高载荷工况条件下使用的摩擦材料。
