因此，要实现东鞍山含碳酸盐铁矿石中铁矿物和石英的有效分离，关键是如何在反浮选之前预先将菱铁矿分离出去，或找到能有效活化或抑制菱铁矿的浮选药剂。

Results showed that spraying KCl solution every other day for 15 days from late flowering decreased nitrate content in the leaf and stem, promoted nitrogen redistributed to silique, increased nitrate reductase activity in the leaf. After spraying 1% KCl solution does not affect the fresh weight of rapeseed. And more obvious differences between the species, different varieties of the same deal with the differences between the more significant.

结果表明，喷施氯化钾溶液能有效降低油菜茎叶硝酸盐含量，与喷施硫酸钾溶液和清水相比达到了显著水平；有效促进了氮素向角果分配；喷施氯化钾还可以增强叶片硝酸还原酶的活性，但不影响喷洒后采样时油菜总的鲜质量；而且品种之间处理后的差异比较明显，同一品种不同处理之间的差异也比较显著。

Spraying KCL solution every other day for 15 days start from late flowering, results showed that nitrate content in the leafs and stems were markedly reduced, Nitrogen redistributed to silique and rapeseed were efficiently promoted, nitrate reductase activity in the leaf were markedly increased. The differences of the same species which under different treatment are more serious, and the differences of the different species which under the same treatment are more significant.

结果表明，喷施氯化钾溶液能有效降低开花期和收获期油菜茎叶硝酸盐含量，与喷施硫酸钾溶液和清水相比达到了显著水平；有效促进了氮素向角果和籽粒分配，显著增强了油菜角果初期叶片硝酸还原酶的活性；同一品种不同处理之间的差异比较显著，品种之间处理后的差异也比较明显。

On the basis of the RMS definition a method for measuring TRMS of distortion sinusoid or non-sinusoid is introduced in the paper.

介绍了一种基于交流信号有效值定义测量失真正弦波或非正弦波真有效值的方法，解决了平均值法在测量失真正弦波时引起显著测量误差的问题。

Technology of coal of gush of blast furnace double gun solves blast furnace coal effectively to compare current velocity of the coal fines when rising fast, coal fines and sirocco mix inadequate, cause efficiency of combustion of blast furnace coal fines this technique still can reduce low problem; effectively remove dust the carbolic content in ash, energy-saving to the enterprise decrease platoon and clean production to having active sense.

高炉双枪喷煤技术能有效地解决高炉煤比提高时煤粉流速快，煤粉和热风混合不充分，致使高炉煤粉燃烧效率低等新问题；此项技术还能有效降低除尘灰中的碳含量，对企业节能减排和清洁生产有着积极意义。

A transportation engineering research and development program assessment method basing on DEA is formulated for prediction of efficiency index, production possibility set's restraint coefficient and inputoutput slack variable. Then use the reciprocal process of principle factor method to calculate the effective availability of research and development personnel and funds.

并采用构建基于投入的交通科技项目C^2R模型，分析投入因子的效率评价指数、生产可能集约束系数和投入／产出松弛变量，结合因子分析逆向求解得到投入指标的有效值，从而得出交通科技项目投入人员及经费的有效利用率。

Because a bulk smoothing capacitor is usually installed on the DC side of many AC to DC converters, the characteristics of harmonic loads will be influenced by this capacitor. Nowadays, shunt active power filters can't reduce harmonics effectively for this voltage type harmonic-producing load. Therefore, a series active power filter is designed to meet the requirements of voltage-sourced harmonic loads. Both source current and load voltage are detected in order to reach the compensation voltage for the SAPF.

由於许多交直流电源转换器均在直流端并联一直流电容以作为稳压之用，此大电容将造成负载谐波特性的改变；此类谐波源负载，如果使用现今常见的并联型主动式电力滤波器并不能很有效解决此类谐波问题；因此本文将采用串联型主动式电力滤波器，并配合同时量测电源电流及负载电压的混合式控制模式，即可有效解决此类谐波问题。

Paper soap flakes contained decontamination factor of efficient and effective removal of the common bacteria on the skin cells and necrosis; deep clean pores, remove smell and can effectively moisturize the skin, easy to carry, with the use of admission.
