The design method is described, and the calculation results are presented under the standard air conditioning condition. The working process of the two-stage expander is discussed, and the difference between the two-stage expander and the conventional one is stated. In addition, the influence of the dip angle on the expansion chamber volume is analyzed. The results show that the dip angle has little effect on the expansion chamber volume and it is suggested that the effect may be neglected in the expander design.

介绍了该膨胀机的设计方法，给出了标准空调工况下的计算结果，详细讨论了两级旋叶式膨胀机的工作过程，并对两级膨胀机与传统旋叶式膨胀机的区别进行了论述，最后分析了滑片倾角对工作腔基元容积的影响，结果显示，滑片倾角对工作腔基元容积的影响很小，在膨胀机的设计过程中忽略滑片倾角的影响是合理可行的。

However, I was so Enamour'd of this Place, that I spent much of my Time there, for the whole remaining Part of the Month of July; and tho' upon second Thoughts I resolv'd as above, not to remove, yet I built me a little kind of a Bower, and surrounded it at a Distance with a strong Fence, being a double Hedge, as high as I could reach, well stak'd, and fill'd between with Brushwood; and here I lay very secure, sometimes two or three Nights together, always going over it with a Ladder, as before; so that I fancy'd now I had my Country-House, and my Sea-Coast-House: And this Work took me up to the Beginning of August.

第二天，十九日，我带着事先做好的两只小袋子回去装运我的收获物。但是，当我来到葡萄堆前面时，原来饱满完好的葡萄，现在都东一片，西一片被拖散开，有的被践踏得破碎不堪，有的则已吃掉了。眼前的情景一片狼籍。这不禁使我大吃一惊。看来，附近一定有野兽出没；至于什么野兽，当然我无法知道。

The spore germination and gametophyte development of 21 ferns are studied. It indicates that :① the development period of prothallium and young sporophyte of the same species is different due to seeding time of spores;② the optimal temperatures of spores germination and gametophyte development of 21 ferns are about 15 -24 ℃;③ the rate of spore germination of rare ferns is much lower than the ferns which occur large populations in nature;④ the treatment with GA 3 can accelerate the germination of the spores;⑤ the prothallium changes from large to small, green to yellow when young sporophyte comes out. The prothalliums of all 21 ferns die away after the appear of the 3rd leaf of sporophytes;⑥ shapes of the 1st and 2nd leaves of the young sporophyte are different from those emerged later;⑦ spores cultured in dark can not germinate;⑧ a prothallium can develop only one young sporophyte though it has many archegoniums, and the spore propagation with leaf mould substrate is an economical method.

摘 要：以腐叶土为培养基质，对 21 种蕨类植物进行了孢子萌发和原叶体发育的研究，结果表明：①不同时期播种的同种蕨类的孢子，发育出原叶体和幼孢子体所历经的时间长短不同；②孢子萌发和配子体生长发育的适宜温度约为 15 ～ 24 ℃；③稀有蕨类的孢子萌发率低，而在野外能形成较大种群的蕨类的孢子萌发率高；④用 GA 3 处理孢子可以促进萌发；⑤当原叶体上长出幼孢子体时，原叶体由大变小，由绿变黄， 21 种蕨类的原叶体都在幼孢子体上长出第 3 片叶时消失；⑥幼孢子体上长出的第 1 、 2 片叶在形态上与以后长出的叶不同；⑦孢子萌发需要光；⑧ 1 片原叶体尽管有多个颈卵器，但仅发育出 1 株幼孢子体；⑨利用腐叶土进行蕨类孢子繁殖是一种经济实用的繁殖方法。

Take the opportunity of this project, theoretical and experimental researches on the high-efficiency evaporator used in a large quick-freeze equipment have been done. The main work of experimental research is as follows:(1) Compare and analyze the influences of structural parameters on the heat transfer coefficient of an evaporator. The calculation results show that, under non-freezing conditions, the structure possessing the highest heat transfer coefficient is the one with circular fins, equilateral-triangle arranged small tubes and varying fin-spacing.
