According to the composting principle and the correlation between the forms of heavy metals and biological efficiency, combining with the controlling means of heavy metals' activity, this test studied the effect of passivation reagents including fly ash, phosphorate rock, zeolite, peat and lime on the forms and the biological efficiency of heavy metals; and the different perception of different passivation reagents were screened and optimized. Basing on the study, the adsorption mechanism of passivation reagents on heavy metals in sewage sludge composting was discussed, and the transformation mechanism of organic forms of heavy metals was also studied through some methods including dialysis and G-75 gel chromatogram separation etc.

从整个生育期看，氮利用效率高的水稻光呼吸速率较低，其相对光呼吸较小；氮利用效率低的水稻光呼吸速率较高，其相对光呼吸较大。

As a fast TDIE solver with high accuracy and efficiency, plane wave time domain algorithm is studied deeply in this thesis. The implementations of two-level and multilevel PWTD-enhanced MOT schemes are described and the numerical efficiency is presented.

论文还深入研究了一种高精度、高效率的TDIE加速算法——时域平面波算法的理论基础、数值实现的关键技术，以及两层、多层PWTD加速MOT的实现方案、程序流程以及数值性能。

However, the distributional firm, specialized transaction producer (or sup- plier), differs from the manufacturing firm in terms of the economic nature. Information technology promotes market transaction efficiency, stimulates distributional industry development, and at the same time promotes management and control efficiency within fir...

但流通企业具有不同于生产企业的经济性质，其本质是交易的专业化生产者；信息技术提高市场交易效率，推动流通产业发展，同时也提高企业管理和控制效率，使流通企业比生产企业更容易利用品牌和统一经营模式进行"复制"和"选择性干预"，实现分店扩张。

We found that in the case of neglecting magnetic shear, the plasma current also can be driven by the shear Alfvén wave and the circularly polarized wave, respectively, the efficiency of current drive in the rotation plasma is independent of the plasma density In addition, it is found that whether m=0 or m≠ 0, the effect of the magnetic shear on the compressional Alfvén wave current drive makes the efficiency be dependent on the plasma density and inversely proportional to it.

当考虑旋转效应而不考虑磁剪切效应时，等离子体平板模型下平面极化压缩阿尔芬波能够驱动旋转等离子体电流，驱动效率也与等离子体密度无关，却与旋转大小成正比，这与Avinash[Phys Plasmas 4，2204（1997）]的结论一致。我们发现在这种情况下剪切阿尔芬波和圆偏振阿尔芬波都可以驱动旋转等离子体电流，旋转效应引起的电流驱动与密度无关。

Thus industry profit is positive while both consumer and operator welfare reach social optimum. Static efficiency and dynamic efficiency no longer conflicts with each other. On the contrary they could be gained simultaneously.

在这种状态下，竞争性均衡能够在不损失消费者静态福利的前提下，实现产业的持续创新，静态效率和动态效率得到了完美的统一，我们称之为"理想的均衡状态"。

It believes that the barycenter of carrying out the scientific development conception is to potentiate institution reform, so that the engine of the development of China will turn from institution efficiency to framework efficiency.

在此意义上，本文从政治经济学的角度，对"科学发展观"做了尝试性的诠释和解读，认为落实科学发展观的重心在于加强制度建设，使经济发展由制度效率提升逐渐转向结构效率提升。

Efficiency: efficiency is the base of the achievement, without which all will be prate

高效：高效是我们实现目标的基石，没有效率，一切都是空谈
