A preliminary study was made on the habitat and activity of E. sinensis in Lunghwa area,a suburb of Shanghai, from January to August 1959. Out of 53 houses examined, 27 (50.9%) were found to be infested with this cockroach—afact which indicated the wide distribution of the roach in the rural area. The main breedingplace, according to the present observation, is the loose soil under the kitchen stove. 24-hour observation was carried out to determine the activity of E. sinensis,and the recordwas made hourly.

A preliminary study was made on the habitat and activity of E. sinensis in Lunghwa area,a suburb of Shanghai, from January to August 1959. Out of 53 houses examined, 27 (50.9%) were found to be infested with this cockroach—afact which indicated the wide distribution of the roach in the rural area. The main breedingplace, according to the present observation, is the loose soil under the kitchen stove. 24-hour observation was carried out to determine the activity of E. sinensis,and the recordwas made hourly. It was found that the roach is chiefly nocturnal in habit. It appeared at 7P.M., and reached the peak of its activity between 8--11 P.M. Gradual quiescence ensued until6 A.M. at which time it disappeared almost completely from the surface of the soil. The majority of the population was found 2.5--4 cm. under the ground during day time,the deepest at. 5 cm. In the night, most of them were found on the surface of the soil or withinthe range of 1 cm. underneath, the deepest at 3.5 cm. The average crawling speed was also determined as follows: 1512.3 cm/min. 650cm/min and nymph 474.29 cm/min. Of the roaches 84.37% showed their activity within the rangeof 30 cm. on the ground near the base of the kitchen stove.

本文报告了中华地鳖活动习性的观察结果:调查了53户农村住宅,发现中华地鳖的户数有27户(50.9%),证明它的分布较为普遍,并表明它的孳生地点主要是在靠灶墙足的松土中。 它的活动时间自晚7时开始,8—11时达高峯,随后逐为减少,至翌晨6时全部消失 于地面。爬行速度,雄虫1512.3厘米/分钟,雌虫650厘米/分钟,若虫474.29厘米/分钟。白昼它在土中的深度以2.5—4厘米之间为最多,最深可达5厘米,但在夜晚,则以地面及1厘米深度处为多,最深仅达3.5厘米,活动距离的测定看出,占84.37%虫数是活动于30厘米距离之内,未见及活动于高出地面所在,说明它的活动范围较为狭窄。 并对它的孳生地,分布,活动的时间性及机制,与人类的关系等问题作了较详细的讨论。

A detailed analysis of steady state heat transfer is made in this paper for a conical focusing solar energy collector with a cylindrical glass cover around the absorber. The equilibrium temperature under various conditions have been calculated using a computer. The influence of the diameter of the absorber, wind speed and the emissivity of the absorber surface on the equilibrium temperature have been discussed. The calculation shows that using the selective coating and the cylindrical glass cover both are the...

A detailed analysis of steady state heat transfer is made in this paper for a conical focusing solar energy collector with a cylindrical glass cover around the absorber. The equilibrium temperature under various conditions have been calculated using a computer. The influence of the diameter of the absorber, wind speed and the emissivity of the absorber surface on the equilibrium temperature have been discussed. The calculation shows that using the selective coating and the cylindrical glass cover both are the effective means to improve the thermal performance of the collector. The cylindrical glass cover can also make the collector work more steadily. A design of a solar autoclave based on this analysis will be available for the rural areas in China where are plenty of sunlight but lacking in fuel.

本文对带有圆管形玻璃罩的圆锥面太阳能集热器进行了稳态传热分析。用电子计算机计算了各种情况下的吸收器平衡温度。讨论了吸收器直径、风速和吸收表面发射率对平衡温度的影响。计算表明,使用选择性吸收涂层和圆管形玻璃罩都是改善集热器热性能的有效措施。采用玻璃罩还使集热器工作更为稳定。基于本分析设计的太阳能消毒器,对于我国日照丰富、但缺乏燃料的农村有一定的使用价值。
