The locust breeding area is considered as a kind of ecological geographical units. Some ofthe natural geographical characters consisting of all types of the oriental locust breeding areas aregiven, and the distribution of four main types of the areas in China, has also been discussed briefly. These four types are lake shore, sea coast (and subcoast),river flood area and internal plainflood area. Each type comprises of one or more heteromorphical sub-structures. The phenomenon of transformation and diversion among these sub-structures in the progression of long termsuccession are developing continuously. And since there are some homologous factors consisted ofamong the four areas, and one main topographic facter,such as removement of a certain large rivercourse as Hwang-ho, has made a foundational effect on all of them at the young stage of develop-ment. Such transformation are also occurred among the four types. These four types have separately their own specific characteristics at different stages on the wayof succession. Such characteristics are also reflected on the locust population dynamics which cor-respond to the limiting affect of the environmental factors. Under natural condition the expansion and contraction of the locust areas are going on inter-mittently. Some sectional stages have also showing either in the course of development or on theway of their disappearance. Such sectional phenomena seem to refer a relative static period in theprogression of succession, and it may also display a certain character of a natural sequence. Locust area can be obliterated either by the influence of natural factors or by the artificialoperations, but the degree of obliteration is decided upon what kind of environmental factor hasbeen disappeared. For example, the absence of certain secondary factor can only to make a tem-porary change as comparing with primary factor does. However in case of the effects could beaccumulated continuously with time, the later factor can also substitute the doing of the fore ones.

蝗区可看成是一类自然生态地理单位,本文列举了蝗区的共同生物地理特征,并摘要叙述了四类主要蝗区在中国的分布。这四类蝗区是滨湖、沿海、河泛与内涝。每类蝗区中包括有形态与性质均不相同的异型次级结构,次级结构能互相转化,并可导致蝗区类型间的转化。四类蝗区各有它的形成过程和表现于飞蝗发生动态上的特殊规律,但四者在形态解剖上有共同的特征,并在最初形成因素上都直接或间接与黄河等大河道的变迁相联系。此外,四类蝗区在扩张与收缩过程中,都呈现阶段现象,此阶段现象系蝗区变化中的相对稳定性的标志,在某种程度上也体现了自然变化规律的顺序性。蝗区发生地的消灭决定于主导环境因素的变化,如第二、三类因素消灭,仅能实现临时性的改造,只有在第一类因素消灭后方能达到根本改造,但是二、三类因素在一定时间内的量变积累,亦可以导致第一类因素发生根本性变化。

The influences of heat setting conditions on the structure of PAC fibres investigated from several approaches like thermal swelling retractions,X-ray diffraction and studies of mechanical properties.The as-spun fibres were dried,heat set in dry state,steam-set relaxed,hot drown once more,and steam-set relaxed again.Each heat setting treatment left a mark on the structure of the fibre.For instance,hot drawing would impair the order,cause internal stresses to occur within certain maoromolecular segments and pro-duce defects and distorsions in the paracrystalline structure;the effects of steam setting,however,would go just by contraries.In conjunction with the studies of mechanical properties,it was discovered that the primary factor which influenced the loop strength of the fibre was the breaking extension,while the perfection of crystallization in the paracrystalline region was secondary.

本文从热溶胀收缩,X-光衍射和机械性质几个方面,观察热处理条件对丙烯腈三元共聚纤维(PAC纤维)聚集态结构的影响.成形后的纤维经过干燥、干热定型、松弛汽蒸定型、再次热拉伸和再次松弛汽蒸定型,每一次热处理都在纤维的聚集态结构上留下印记.拉伸会降低序态,在无定形区的某些大分子链段中产生内应力,在蕴晶区造成结晶缺陷;汽蒸定型的作用则刚巧相反.联系纤维的机械性质,发现决定纤维钩强的主要因素是纤维的断裂伸长,蕴晶区的完整程度是次要的.

Clayey Silt is a slightly plastic sandy loam the plasticity index(Ip) of which is between 3~10 and its liquefaction occurred in a large area during Tangshan earthquake on July 28, 1976.Formulae with 4 or 5 primary factors for predicting liquefaction potential of clayey silt are presented in this paper. The formulae are derived after analyzing three groups of representative data of clayey silt (involving 126, 166 and 231 points respectively)by using a special computer program prepared by authors.The characteristic of the formulae is associated with a discrimination ratio for liquefaction and non-liquefaction. In addition,they can also be used to choose certain discriminas-tion ratio based on importance of engineering projects.The validity of the formulae is established through checking typical examples from seismic zone with different intensity. A practical application is also mentioned in the end of the paper.
