A narrow pulse excitation current with sufficient peak value can lower perming error with low power consumption but reduce the sensitivity and increase the difficulty of the signal processing.

带有足够高峰值的尖脉冲激励电流能降低剩磁误差，同时也降低了功耗，但是降低了传感器的灵敏度而且信号的处理难度增加。

Bellows Gate Valves However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.

但在大压差工况下，蒸发压力降低，蒸发器负荷需求的液量减少，但实际情况相反，在吸气过热度不变的情况下，由于蒸发压力降低，蒸发器出口压力相应降低，膜片上下的压差变大，使主阀开度增大，供液量增加；但在小压差工况下，蒸发压力上升，蒸发器负荷需求的液量增多，但实际情况是在吸气过热度不变的情况下，由于蒸发压力上升，蒸发器出口压力相应提高，膜片上下的压差变小，使主阀开度减小，供液量减少；在变负荷下亦如此。

Simulation results show that the load control method with variable event timing can effectively decrease the pumping loss at engine partial load condition up to 57%, and the brake specific fuel consumption is improved to 5.63%.

结果表明，采用可变气门开启持续期负荷控制方式可以有效降低汽油机部分负荷泵气损失，最大降低幅度达到57%，同时比油耗降低了5.63%。

The effect of low temperature treatment on DNA methylation level decrease revealed some variety differences. The DNA methylation level in stem apices of the spring radish cultivar'Duanye 13'was somewhat easy to be decreased by low temperature treatment, but that of the winter radish cultivar'Yidianhong'did not decrease when the germinated seeds were treated at 10℃ for 10 days.

萌动种子低温处理降低DNA甲基化水平的效果在品种间存在一定差异，春性品种'短叶13'其DNA甲基化水平比较容易被降低，而冬性品种'一点红'的萌动种子在10℃下处理10d尚不能降低其DNA甲基化水平。

The chromatic aberration was decreased for filler adding, and the decrease was the biggest by CaCO3, the smallest decrease is TiO2. The chromatic aberration decreased gradually with CaCO3 dosage, however, the chromatic aberration changed little when CaCO3 dosage is greater than 20%; also the two-sidedness of paper was improved by filling.

填料的使用明显降低了色差值，其中降低最显著的为碳酸钙，最少的二氧化钛，碳酸钙用量的增大导致色差值逐渐降低，当碳酸钙用量大于20%后，色差值变化很小，但加填改善了色差值两面差的问题。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
