Ericerus pela Chavannes, the insect producing white wax,belongs to Coccidae,Homoptera. The female adult lays eggs while the male larva produces wax, whichis a well-known product from Southwest China. The wax secreted by the malelarvae may be boiled and extracted to result in something known as white wax.Its boiling point reaches above 82-83℃. It has manifold uses. Before WorldWar Ⅱ, besides the consumption at home, th greater part of this product wasexported abroad. The supply of the female adults of this wax insect in the wax-producing districtusually appears short annually, due to a peculiarity in the growth of this creature;and therefore naturally exist two correlative districts, that is a district of adultproduction and one of wax production. As these two.districts are located morethan 500 kilometres apart,every year the female adults ready to be transplantedon he feeding trees in the district of wax production have to be supplied bythe district of adult production, and they must be carried over a long distance.The carriage of the female adults of the wax insect from one place to theother has been practiced for about five hundred years by the people engaged inwax production. This article reports on a test of transportation of the female adults of the wax insect from Paikuowan (白菓湾) in Hweili County (会理县), formerly of SikangProvince to Huhtaokou (核桃沟) in Omei County (峨眉县), Szechwan Province.Investigations in this connection were made from the April 30 to May 13, 1941. It has long been the aim of the growers to produce the female adults of theinsect and the wax in the same locality. With this realized, the area of wax pro-duction would be enlarged, and the quantity of wax increased. However, as the female adults of the insect in the distr .ct of wax produc-tion are subject to such natural adversities as geographical features, temperatureand humidity, parasitic enemies etc., up to the present they cannot be raised andsapplied insufficient quantity in this district. For this reason, to in prove themethod of transporting the adults female insects to the wax-producing district, toShorten the time on the way,and to increase the vitality of the male larvae-all these have become the crucial questions in the promotion of wax production. The principal explanation, knowh for centuries, with regard to the impossi-bility to raise the female adults of the insects in the district of wax productionhas been the peculiar fact that the female larvae could not be carried in quickorder to a place over 500 kilometres apart. The present test has proved that al-though the female larvae were, in the greater part, hatched out on the way, therewere still a part of them reaching the destination in safety. Valuable informat-ion was also obtained on the hatching rate of the male and female larvae on theway, the influence of environmental factors on the sex ratio, the different speciesof parasitic enemies, etc.. It is hoped thet the facts thus ascertained will be ofservice to improving the methods of wax production.

白蜡虫是我国的特产,古代农民远在元朝已有饲养。在过去全国的白蜡年产量约在五万至十万担间,据1918年重庆海关报告有一万一千余担,值银七十七万余海 关两。解放前一、二十年来,由于国民党反动派的不重视和摧残,已逐渐衰落。白蜡是化学工业上的重要原料,用途很广,饲养蜡虫又是西南各省农民的主要副业,而且农民群众已积累了非常丰富的传统经验。因此,为了总结群众经验,发扬科学遗产,改进饲养技术,振兴蜡业,我们希望能引起有关方面的注意和进一步研究,除研究改进白蜡虫的经管技术外,又须注意白蜡在工业上的用途。 白蜡虫的种蜡异地繁荣,在目前已成为自然的形势,而蜡区种虫不能自给,是白蜡业发展上的基本障碍。我们通过本次测验之后,认为我国适于蜡虫(雄虫)繁育的地方很多,如四川、湖南、浙江、安徽、福建、江西、江苏等丘陵地带都可扑虫产蜡,关键问题在于改善运种方法。在目前我国交通运输业已有普遍发展的基础上,只要用航空运种即可在短时间内将种虫运送至全国蜡区。扩大蜡区,增加农民副业收入,发扬我国科学遗产,为国家创造财富,利用益虫为生产服务,在目前已完全有实现的可能。

This paper reviews the observational facts and theories on the airflow over small mountains. Special emphasis is laid to point out and discuss the controversies in the theory of lee waves among different writers. According to present author controversiesare due to (1) the difference in scale of the mountain and (2) the choice of the upper boundary condition. When l is comparable to the critical value , where l is the half-width of the mountain, lee waves occur. When there is an upper solid lid or a discontinuity in the atmosphere lee waves occur.In the first case the forced vibration is in resonance with natural vibration. In the second case there can exist only vibrations of certain wave lengths, which appears as those of the lee wave. The physics of lee waves is thus clear.

本文总结了小地形对于气流的影响。文中着重地指出和讨论了过去背风波理论中的矛盾。作者认为这些矛盾是由于山的大小选择和上界边界条件的选择而引起的。当山的宽度的一半l≈(L_S/2π)时(L_S=u/(g/θ αθ/αz)(1/2)),和当大气中有一个固定的盖或不连续面存在时,背风波出现。 在第一种情况下,山的强迫振动与大气中的自由振动共鸣;在第二种情况下,只具有某些滤长的振动可以存在,这波长就是背风波的波长。这样的讨论背风波的物理意义就清楚了。

1. Firmiana simplex has been cultivated by our Chinese people in both ancient and modein times for medical use, and for the making of furnitures and musical instruments, as well as ornamental tree.2. The distribution of this plant is wide-spread almost through entire China. According to the writer's observation it grows vigorously and reaches its maximum height in the lower part of the Yangtze basin.3. In 1929 Yen states that sex differentiation of Firmiana simplex might be due to the fact of nutrition, the writer, after visiting various parts of China, discovered that everywhere this plant has the same phenomenon of sex differentiation. This fact leads to a new conclusion that sex differentiation in this plant is certainly not entirely influenced by nutrition; it may be due to the historical factor of the plant it-self.4. No phcllum is developed in the hypodermis except in the region of Icnticels. Epidermis, therefore, may grow permanently and never break off. These are very rare even among the perennial woody plants.5. Characteristics which are considered peculiar to Firmiana simplex are: (1) closely arranged epidermal cells may become loose during the increase of the diameter of the branches, (2) rupturing of the fissures on the bark while the branch grows, (3) development of secondary epidermis from the hypodermal cells within the fissures and the lenticels, and (4) continuous division of the epidermal cells. All these characteristics are facts which explain the permanence of epidermis.

1、梧桐具有观赏,药用,制造器物等价值,我国民众自古就加栽培利用。 2、梧桐上分布几遍及全国,据我所见到的是长江中、下游地区所生长的比较繁茂高大,北京的最为矮小,厦门比北京的高大些,昆明虽然不及长江流域的但比厦门的似乎又茂盛高大些。 3、关于梧桐花两性分异,以前以为是养料的关系,但是现在观察了各地的梧桐花,发现它们对于性的分异都是一样之后,我认为造成性的分异可能下仅是单纯养料的问题。也许和有机体自身的历史发展因素有关。 4、苹婆和大多数多年生木本植物相同,它们茎部表皮的寿命不过1年。新枝条的下皮层在当年夏秋之际分化木栓组织。以后,表皮细胞就会枯死脱落。 5、梧桐,除皮孔而外,枝干表皮层之下一概不发生木栓组织,表皮层与枝干同寿,这是多年生树木中少有的微状。 6、梧桐表皮细胞,随枝干之加粗而疏离,又可分裂增多,同时条状裂纹也可以随枝杆直经之增加而开裂加宽,这些都是表皮长生不老的因素。 7、梧桐树皮裂纹中的下皮细胞向外分裂成为次生表皮组织,这是很特别的。
