In this paper the design of an identical-velocity sampler to collect flyash and soot in flue gases is described., The sampler is compact in construction and self-aligning. The velocity in the sampling tube can be accurately maintained in identical with that in the main stream to make the sample representative. It employs the hot filtration process within the furnace to improve the accuracy of its measurement. Besides, it can be used to measure the velocity of the main stream while taking sample. Calibration in cold conditions and testing in hot working conditions proved that this sampler is convenient in use and accurate in measurement.

内燃机台架试验国家标准 GB 1105—74存在一些问题,其中标定功率核算方法的问题是:在不同大气状况下测定结果核算所得的标定功率相差较大,当大气密度小于标准大气状况下的大气密度时核算所得的标定功率偏大,当大气密度大于标准大气状况下的大气密度时核算所得的标定功率偏小。本文从试验及原理上说明其问题所在。从而提出一种新办法(可叫油耗线法),其原则与 SAEJ-270相同,(即从等过量空气系数α下的燃烧效率相同出发,求得在标准大气状况及标定油量下的指示油耗率,据以计算标定指示功率,再计入机械损失的影响得出标定有效功率)。但方法上比较简便,适合我国国情,以试验证明其符合要求。进一步就国外试验标准进行分析,原理上阐明所提油耗线法的合理性及其特殊优点。
