Experimental type of CN-sonde was made to test characteristics of the system, and we performed the laboratory experiments. The experiments suggested that the experimental type sonde had mostly realized the purpose which was chosen at beginning of the project.1.Detectable limit : There was noticeable uncertainty to detect about 1 nanometer size particles, and the number of particles observed experimental type sondes varied from first sonde to second sonde (two experimental types were compared). However, there was little difference between those two concerning detected number concentrations of several nanometer size particles. We could observed 1particles/cm3 at a few nanometer size range.2.Kinds of observation items : Out put corresponding to CN particle concentration, number of rotation of motor/minute, power of laser out put, temperature of chamber, atmospheric temperature, and atmospheric pressure.3.Observable range : Motor pump used here has been used as standard one of optical particle counter which was made to monitor tropospheric and stratospheric aerosol concentrations, and good results were obtained in various fields. Therefore it is possible to operate the CN-sonde in the troposphere and stratosphere (〜35km).4.Portability : Estimated total weight of the CN-sonde is in the range of 7-8kg, and it is necessary to reduce about 1-2kg of the weight to used as the small balloon on the basis of world standard of usage of balloon.Test of the sonde under low temperature conditions will be made within this financial year, and experimental type of the sonde will be established after the low temperature test.

为了测试系统的特性，制作了实验型的cn -探空仪，并进行了室内实验。试验结果表明，实验型探空仪基本实现了工程开始时选定的目的。检测限：检测约1纳米大小的颗粒存在明显的不确定性，并且实验型探空仪观察到的颗粒数量在第一探空仪和第二探空仪之间存在差异（比较了两种实验类型）。然而，这两种方法在几种纳米级颗粒的检测数量浓度方面差异不大。在几个纳米尺度范围内，我们可以观察到1个粒子/cm3。2 .观察项目种类：与CN粒子浓度相对应的输出量、电机每分钟转数、激光输出功率、腔室温度、大气温度、大气压力。观测范围：本文所使用的电机泵已作为光学粒子计数器的标准之一，用于对流层和平流层气溶胶浓度的监测，并在各个领域取得了良好的效果。因此，可以在对流层和平流层（~ 35km）操作cn -探空仪。便携性：cn -探空仪的总重量估计在7-8kg之间，根据世界气球使用标准，作为小气球使用需要减少1-2kg左右的重量。在本财政年度内对探空仪进行低温条件下的试验，并在低温试验后确定探空仪的实验型号。
