The natural vegetation of Shantung Province, in the north temperate zone, is of the aestisilvae type. As the natural conditions vary in different parts of this province, the vegetation may be divided into the following four regions: 1. Alluvial plain of the Yellow River: This region is located at the northern part of this province. The saline soil is unfavorable for the growth of most plants. The following plants are characteristic: Tamarax chinensis, Apocynum venetum, Suaeda salsa, S. glauca, Artemisin capillaris,...

The natural vegetation of Shantung Province, in the north temperate zone, is of the aestisilvae type. As the natural conditions vary in different parts of this province, the vegetation may be divided into the following four regions: 1. Alluvial plain of the Yellow River: This region is located at the northern part of this province. The saline soil is unfavorable for the growth of most plants. The following plants are characteristic: Tamarax chinensis, Apocynum venetum, Suaeda salsa, S. glauca, Artemisin capillaris, Aeluropus littoralis, Miscanthus sinensis, Phragmites karka, Carex sp. etc.. 2.Western Shantung plain: This region is located at the western part of the province. Most of the land is under cultivation and the soil is rich in calcium. There is no forest. The common trees are Populus tomentosa, P. alba P. davidiana, Ulmus spp. etc., and the herbaceous plants are Cynodon dactilon, Digitaria sanguinalis, Echinochloa colonum, Imperata cylindrica, Chenopodium album, Convolvulus chinensis,Xanthium japonicum, Crypi saculeata, Scirpus maritimus etc.. Plants which grow in the lake district largely belong to Phragmites communis, Scirpus maritimus, Zizania latifolia, Euryale ferox, Trapa bispinosa etc.. 3.Central South hilly region: This region has mostly been transformed into farms for a long time. On the hilly region there are still some remnant forests. The important trees are Pinus tabulaeformis, Biota orientalis. Quercus acutissima, Q. variabilis, Betula chinensis, Tilia mongolica etc.. On account of calcareous soil in this region, Biota orientalis is found most extensively. Gramineae leads all other herbaceous plants in abundance. The following species such as Arundinella amomala, Bothriochloa ischaemum, Setaria viridis, Pennisitum flaccidum etc. have a wide distribution. 4. Shantung Peninsula: The common native plants in this region are Pinus densiflora, Quercus dentata, Q. acutissima, Robinia pseudoacacia, Acer mono etc.. Pious densiflora is a native plant which grows all over the hilly region. Herbaceous plants are mostly Thymus serpyllum, Setaria viridis, S. lutescens etc.. Due to the oceanic climate with higher precipitation and humidity, plants enjoy a more vigorous growth than those in other regions. There develops a richer flora, some even with warm temperate elements.

The continuous decrease of the viscosity of rubber solution in toluene or benzene under nitrogen atmosphere with the addition of an antioxidant has been confirmed to be the result of photochemical degradation by the diffused sunlight in the laboratory. An equipment for the determination of intrinsic viscosity under nitrogen atmosphere in the darkness is hereby described. It gives reproducible viscosity data and reliable values of intrinsic viscosity.A sample of first grade smoked sheet of plantation Hevea rubber was fractionated under nitrogen atmosphere in the darkness. The result shows a rather wide distribution in molecular weights, including a group of molecules having molecular weight above 2-3×10~6, This is in agreement with some recent results of fractionation studies found in literature. _n of our sample is 1.75×10~6, while an osmotic measurement gave _n =1.3×10~6.

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。
