本试验研究了5种不同颗粒粒径的蛭石对其物理性质、水分常数和孔雀草苗期生长的影响，结果表明，基质总孔隙度在70%～90%，大小孔隙比在1：2左右时均能满足作物苗期生长的要求。

This essay analyzes the method and procedure of ice-making recorded in Huai Nan Wan Bi Shu, and creatively proposes that the principle of "ice-making in summer" is refrigeration through the quick evaporation of water to absorb heat under low pressure, and that ice is made on the fine silk at the mouth of an urn, but not inside the urn at its bottom as it was conventionally thought. The essay points out three necessary conditions which should be fulfilled in order to realize "making ice in summer": low relative humidity (less than 26%), large volume of the urn (about 100 L) and proper air temperature (about 20℃).

分析《淮南万毕术》所载制冰方法和过程，提出低压下水快速蒸发吸热制冷是"夏造冰"的制冰原理；结冰的部位不是传统观点所认为的瓮底，而是在瓮口的嫌上；指出要实现"夏造冰"，需满足三个条件：相对湿度低（低于26%）、瓮的容积大（100升左右）、空气的温度适当（20℃左右）。

The study on the hardening mechanism of the soft soil with the materials shows that the hardening procedure can be divided into three stages:(1). Hydrating and dissolving stage, when material A and material B of the high-water-content and quick-setting materials respectively dissolve and balance in water.(2). Gel and consolidating stage, when the materials hydrate into calcium crystal and the ion exchange and aggregation of soil particles occur in an alkaline environment.(3). the structure developing stage, when the calcium crystals connect each other, absorb and crystallize the water around; the hydrate remnants, calcium hydroxide, carbonate continuously in water and in the air.

本文对高水速凝材料-软土硬化机理的研究表明，高水速凝材料-软土的硬化过程可分为三个阶段：①水化溶解阶段：主要为高水速凝材料的甲、乙料分别与水的溶解、维持平衡阶段；②胶凝固化阶段：主要为高水速凝材料的水化反应生成钙矾石晶体以及土颗粒在碱性环境中发生离子交换和团粒化作用；③强度增长阶段：钙矾石晶体相互连接，大量吸收周围环境中的水分，并将水分变成自己的结晶水；水化残余物氢氧化钙在水中和空气中发生碳酸化作用。

It was full of sap, full of leaves, and full of boughs; but now in vain does the busy art of man pretend to vie with nature, by tying that withered bundle of twigs to its sapless trunk; it is now at best but the reverse of what it was, a tree turned upside-down, the branches on the earth, and the root in the air; it is now handled by every dirty wench, condemned to do her drudgery, and, by a capricious kind of fate, destined to make other things clean, and be nasty itself; at length, worn to the stumps in the service of the maids, it is either thrown out of doors or condemned to the last use - of kindling a fire.

如今变了样，却还有人自作聪明，想靠手艺同大自然竞争，拿来一束枯枝捆在它那已无树液的身上，结果是枉费心机，不过颠倒了它原来的位置，使它枝干朝地，根梢向天，成为一株头冲下的树，归在任何干苦活的婆子的手里使用，从此受命运摆布，把别人打扫干净，自己却落得个又脏又臭，而在女仆们手里折腾多次之后，最后只剩下一支根株了，于是被扔出门外，或者作为引火的柴禾烧掉了。

它曾生气勃勃，枝繁叶茂，但如今爱管闲事的人却动手把枯枝捆扎于它那枯桩上，装模作样地同自然徒然抗争。如今它充其量只是以前模样的倒转——一棵本末倒置的树，枝条伏地，根部朝天，听由脏兮兮的女佣随手使唤，并且被无常的命运捉弄，注定要去清扫他物，把自己搞得污秽不堪。最后，被女佣用成一根光杆儿，要么被扔出门外，要么最后充当引火的木柴。

Never, in general terms, does a Puerto Rican say, nor does he know how to say "no":"We'll see,""I'll study the matter,""I'll decide later"; when a Puerto Rican uses these expressions, it must be understood that he does not want to; at most, he joins the si with the no and with the affirmative and negative adverbs makes a conditional conjunction, ambiguous, nebulous, in which the will fluctuates in the air, like a little bird aimless and shelterless on the flatness of a desert....

总的来说，波多黎各人不说"不"字，也不知道该怎麼启口。"我们再看看吧。""这件事我再想想。""我过后再决定吧。"当波多黎各人这样说时，这意味著他不愿意这麼做。最多也只能理解为他把"不"和"是的"这两个词放在一块，作为条件句的连词，使意思模稜两可，含糊不清。他拿不定主意，他的意愿像无处藏身的小鸟在沙漠上无目标地飞著。

The stealth warplane for the microwave radar usually have complicated structures with the coating of wave absorption. On the base of calculation and modeling of the geometrical structure of the warplane in real size, the HF RCS of the air crafts under two different polarizations in different direction have been calculated with the FDTD. The result shows that the above mentioned stealth warplane have the obvious characterstics of frequency resonance, polarization and the relatively large RCS in HF Band 10-30dBm2, which can be used as the theoretical reference for selection of working frequency for sky wave OTH Radar and it also means that the sky wave OTH radar has good capability of anti-stealth targets quantitatively.

对微波雷达具有隐身作用的飞机，其形体较为复杂且表面涂敷有强吸波材料在对一种具有隐身几何外形结构实际尺寸飞机进行计算建模的基础上，文中采用FDTD技术得到了两种极化状态下该飞机无涂敷时不同方向上的短波雷达截面RCS值其结果显示了这种隐身几何外形飞机在短波波段有明显的频率谐振特性、极化特性和较大的RCS10-30dBm2，可为天波超视距雷达在选择工作频率时提供理论参考，并定量地说明天波超视距雷达具有较优的反隐身目标能力
