The differentiation states of costae indicates the ways they absorb and transport water, and their ability adapting to the dry conditions, which was elucidated by the following examples: Brachythecium plumosum, because of its thin cell-walls in the costae and the absence of hydrome, assistant and steroid cells, can absorb water and nutrition under shady and moist conditions; Plagiomnium rostratum, though often grows in shady and wet condition, has hydrome and steroid cells, a feature similar to those of xeric mosses, which endows it to grow in the conditions with periodical drought stress during its life cycle; Hygrohypnum luridum is characterized by its slender leaves with only one layer of cells, the thin cell-walls, the absence of filaments on the leaf surface, and the fewer layer cells in the costae, the absence of hydrome and steroid cells. These features make it adaptable to aquatic environments. For Pogonatum inflexum and Atrichum undulatum, their ventral surfaces covered with lamella, while for Racomitrium japonicum, Thuidium cymbifolium, Macromitrium ferriei, Diphyscium fulvifolium, Barbula unguiculata and Ceratodon purpureus, their leaves are strongly mammillose or papillos. Such appendiculate structures made them adaptable to thy conditions.
例如,荫湿生环境下的羽枝青藓Brachythecium plumosum,其中肋细胞胞壁较薄,无导水主细胞和副细胞的分化,也没有厚壁细胞分化,能够在阴湿环境下吸收水分和养分;钝叶匍灯藓Plagiomnium rostratum具有与旱生藓类植物相似的中肋结构,叶片较厚,中肋具导水主细胞,中肋背面具厚壁细胞,这些特点使该种藓类植物能够分布于间隙性干旱胁迫的环境中;水灰藓Hygrohypnum luridum叶片纤细柔弱,仅1层细胞,细胞胞壁薄,叶表无附属结构,中肋细胞层数少,无导水主细胞分化,也没有厚壁细胞,这些特点使得水灰藓'能够生长在水生环境中;东亚小金发藓Pogonatum inflerum和波叶仙鹤藓Atrichum undulatum的叶腹面覆盖着栉片,东亚砂藓Racomitrium japonicum、大羽藓Thuidium cymbifolium、福氏蓑藓Macromitrium ferriei、东亚短颈藓Diphyscium fuhifolium、扭口藓Barbula unguiculata和角齿藓Ceratodon purpureus的叶片表面有乳头状突起或疣状物,这些附属结构使它们能够适应于旱生的环境中。

A boiler water controlling system with basifier a mg/L Na3PO4+b mg/L NH3+c mg/L NaOH is investigate in the paper. Several calculate methods are discussed and the precision pH value calculating equation is proposed for a cycle chemistry system that has seven changing parameters coexisting together, i. e. a mg/L Na3PO4+b mg/L NH3+c mg/L NaOH+d mg/L H2SO4+e mg/L CH3COOH+f mg/L CO2+g mg/L SiO2. As an example of equilibrium phosphate treatment, the pH value are obtained and showed in graphics with the four kinds of impurity changing from 0 to 1.0 mg/L. The calculating results can be used in practical boiler water pH value control.
对于一个采用a mg/L Na3PO4+b mg/L NH3+c mg/L NaoH碱化剂的炉水控制体系,主要讨论在炉水中存在d mg/L H2SO4+e mg/L CH3COOH+f mg/L CO2+g mg/ L SiO2 4种杂质时炉水pH值的计算方法,得到通用的pH值计算表达式;并以炉水平衡磷酸盐处理工况为例,计算这4种杂质在0-1 mg/L变化时,其单独或联合作用对炉水pH值的具体影响程度,以6幅图形展示计算结果,该结果可应用于炉水pH值的实际控制。

The achievement of this project can be briefly summed up as following:(1)the carbon contributing to karst processes mainly comes from ecological system itself under the condition of existence of vegetation and soil covers;(2)results indicates that the depositing processes of rainfall to CO2 is an important "sink" to global carbon cycle;(3)owing to the differences of vegetation and surface covering, the adjusting effect of ecosystem to environmental humidity, temperature and CO2 concentration near surface air which indicates different benefit of preventing water and soil from lose is marked;(4)the preponderant species of vegetation in the karst ecosystems which have different kinds of carbonate rocks are obviously variant, and this situation results to the clearly differences of the micro - habitat , structure of surface cover and water holding capacity;(5) the relevant study showed that the carpophagous animals and birds make a important role in the spreading of vegetation seeds. The designed experience for the study of seed reservoir was not able to obtain a satisfactory result.
主要研究成果包括:通过对表层系统碳库的研究,认为在有土壤和植被覆盖时,岩溶作用过程中的碳主要来自生态系统本身而不是母岩;降雨对大气碳具有重要&沉淀&作用,是碳的一个重要汇;不同植被类型表层岩溶系统对系统水份、空气湿度、气温、土温和近地表 CO2浓度等具有明显调节作用,具有不同的水土保持效益;不同母岩的岩溶生态系统的植被优势种、属差异明显,由此形成的小生境、地被物及其持水性差异巨大;对典型岩溶表层系统种子库的试验研究没有取得满意结果,但食果动物、鸟类对种子传播起到一定作用。

The test results showed that when the cycle water flow was 65m^3/h and the oxygen flow was 1, 2,……, 10L/min, the relationship between the dissolved oxygen and oxygen flow in the water was y=0.1009χ^2+0.0594χ+5.9588 (r=0.9927). According to the mass balance principle, the maximum oxygen utilization rate of oxygen cone was calculated at 84.56%. Under the condition of the maximum oxygen utilization rate of oxygen cone, according to the rate of Nile tilapia oxygen consumption, the number of oxygen cone was projected in industrialized fish farming system. It provided the basis for oxygen supply system design in industrialized fish farming system.

I'm not saying my route is the most normal, as I wear wellies to cycle to work (water comes over my ankles when I'm cycling through the water filled ruts), but for people like me that actually use their bikes daily for fitness, transport and fun, grinding substance terrain and grass filled meshes make the cost of running a bike higher.
我不是说我的路线是最正常的,因为我穿wellies向骑自行车上班(水是我的脚踝当我骑自行车通过水填补ruts ),但对于像我这样的人,实际上每天都使用他们的自行车的健身,运输和乐趣,研磨物质地形和基层填补网格使运行成本较高的自行车。
