This paper makes comparison of two methods used for estimating the leaf-areas of vegetable crops in the field. The results showed that the correlation method was useful and accurate for crops possessing uniform and large-sized leaves, such as the cucumber, etc. and the other method, based on leaf weight appeared to be suitable for such type of crops like leguminous plants with leaves numerous in number but small in size. Comparison of the suitability of leaf fresh weight with dry weight as a basis for leaf area...

This paper makes comparison of two methods used for estimating the leaf-areas of vegetable crops in the field. The results showed that the correlation method was useful and accurate for crops possessing uniform and large-sized leaves, such as the cucumber, etc. and the other method, based on leaf weight appeared to be suitable for such type of crops like leguminous plants with leaves numerous in number but small in size. Comparison of the suitability of leaf fresh weight with dry weight as a basis for leaf area determination showed that the former was better in that it could be directly applied, thus simplifying the procedure, without affecting accuracy of results.

本文是以主要蔬菜为对象,从田间大量测量叶面积的要求出发,研究相关法和称重法的适用范围和测量准确性。结果表明叶形大而整齐的种类如黄瓜、白菜等以相关法测量最为简便,结果准确;叶形小而叶数较多的豆类等以称重换算为宜。比较鲜重和干重换算的测量结果,认为用鲜重既可进一步简化手续,而不影响测量结果。

Pulse emission current at the inflection point on I-U curve of a thermionie eathode can be measured rapidly by means of a circuital technique. This method can prevent the eathode from suffering injury during the measurement. So that it can be used to compare the emission levels between different thermionie cathodes, and to monitor the changes of activation of cathodes during life test. The principle of the rapid-measure-ment of pulse emission current at the inflection point on I-U curve of the thermionie eathode...

Pulse emission current at the inflection point on I-U curve of a thermionie eathode can be measured rapidly by means of a circuital technique. This method can prevent the eathode from suffering injury during the measurement. So that it can be used to compare the emission levels between different thermionie cathodes, and to monitor the changes of activation of cathodes during life test. The principle of the rapid-measure-ment of pulse emission current at the inflection point on I-U curve of the thermionie eathode is discribed. Autodisplay of the inflection point on the I-U characteristics is realized. The method of verification of its correctness is given. A great deal of mea-surements on various thermionie cathodes show that the instrument is of practical value. Finally the measuring error of the instrument is diseussed.

Tests have been made on the measurement of steam-water mixture quality with an ASME diameter-tap orifice. The orifice is mounted in a pipe with I. D. of 58.5 mm and the ratio of its hole diameter to pipe diameter is 0.2598. Tests are conducted under pressures from 177 to 208 kg/cm2 and with steam qualities varying between 0.21 and 0.97. Based on a conventional separated flow model, a modified relationship is developed with the help of introducing an additional assumption of α =α. Test data in the range with...

Tests have been made on the measurement of steam-water mixture quality with an ASME diameter-tap orifice. The orifice is mounted in a pipe with I. D. of 58.5 mm and the ratio of its hole diameter to pipe diameter is 0.2598. Tests are conducted under pressures from 177 to 208 kg/cm2 and with steam qualities varying between 0.21 and 0.97. Based on a conventional separated flow model, a modified relationship is developed with the help of introducing an additional assumption of α =α. Test data in the range with ReTP=1 .5×10s can be well correlated using this relationship. The RMS error is ±0.0401 as compared with that reported by Murdock, which is±0.0440. The accuracy of measurement has found to be influenced by flow characteristics during test.

对用径距取压的ASME标准孔板测量含汽率进行了试验研究。管道内径58.5毫米,m=0.2598,试验压力177~208公斤/厘米~2,测量的含汽率范围0.21~0.97。在分相流动模型的基本假定下,引入一项补充假定(α=α′),得到的修正分相流动模型表达式,对于本文中Re_(TP)≥1.5×10~5的试验数据能较好地进行综合,平均标准离差为±0.0401。与Murdock的数据(中压)相比,离差为±0.044。在试验条件下还发现流动特性对测量准确性有一定影响。
