为了研究稻瘟病等病害的发生与水滴消长的关系,必须要有连续准确记录露水消长动态的仪器。因此,作者参考日本桥本晃提出的原理,经过三年研究,试制成功了重量式结露计,经过技术鉴定和野外使用,认为本仪器能准确地反映生物体、非生物体表面露水的生消及露量的大小,灵敏度较高,稳定性较好,坚固耐用。现简介如下。一、工作原理重量式结露计根据虎克定律测量露量,其工作过程(见附图)如下:集露框承接凝露渐渐产生重力使垂直升降杆向下位移,连接在下横梁的测量弹簧伸长位移,带有自记 In order to study the relationship between the occurrence of rice blast and other diseases and the drop growth, it is necessary to have a continuous and accurate record of the dynamics of dew growth. Therefore, with reference to the principle proposed by Hashimoto, Japan, after three years of research, the author succeeded in making a weight-type dew-point meter. After technical appraisal and field use, the author thinks that this instrument can accurately reflect the dew on the surface of organisms, non-organisms Elimination and the amount of dew, high sensitivity, good stability, durable. Now the introduction is as follows. First, the working principle of weight dew condensation meter according to the Hooke’s law to measure the amount of dew, the working process (see photo) as follows: set the dew frame condensation to gradually produce gravity to lift the vertical lift rod down, connected to the lower beam measuring spring Elongation, with self-recording
