There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.

Yoshida and Parao (1976) reported that CO2 enrichment and shading during the reproductive stage, influenced very much the sink size of rice plant. It was also reported that there was a high positive correlation between solar radiation during the reproductive stage and final grain yield.

Yoshida 和 Parao （1976）报导了生殖生长阶段 CO2增加和遮荫大大影响水稻植株养分汇的大小，也报导过生殖生长阶段日光辐射和最终产量呈显著正相关。

Reflecting layer is composed of TiO2 large nano-particles with mean grain size of 250nm or 150nm prepared using organic alkali tetramethylammonium hydroxide as peptizer. Nano-crystalline TiO2 porous thin film composed of small nanocrystalline (10~20nm) was used as a substrate layer to absorb large amount of dye molecules.

用有机碱四甲基氢氧化铵做胶化剂制备的两种大粒径纳晶TiO2（粒径为250nm和150nm），用它们分别制备薄膜做为反射层；用小粒径纳晶TiO2(10~20nm)来制备的纳晶多孔薄膜为底层膜，用于吸收大量的染料。

Physiologically, our model estimated 2.6 days to reach the single ridge stage, 5.6d to the double ridge stage, 11.3d to the stamen and pistil initiation stage, 13.1d to the anther separation stage, 15.3d to the pollen mother cells stage and 18.2d to the tetrad stage. Phenologically, estimations were 13.1d to reach the jointing stage, 28.7d to the heading stage, 32.8d to the grain filling stage and 51.5d to the maturity stage. PDT was consequently used as a unified scale for measuring developmental progress of different cultivars under different climates and cultural practices.

经测算，各大麦品种到达单棱期、二棱期、雌雄蕊分化期、药隔形成期、雌蕊柱头二裂分叉期、雌蕊柱头毛状突起期等顶端发育阶段的生理发育时间分别为2.6、5.6、11.3、13.1、15.3、18.2、28.7d，到达出苗期、拔节期、抽穗期、灌浆期和成熟期等主要物候期的生理发育时间为0、13.1、28.7、32.8、51.5d，形成了不同大麦品种在不同气候和栽培条件下统一的衡量发育的定量尺度。

Products is rich, agriculture and service line of business are the economic section with the largest India, main grain crop has Jute, tea, sugar cane, rapeseed and pily; ox, goat, sheep, buffalo to raise a quantity to reside the world for crop of main economy of paddy and wheaten; the India at the beginning of time of the first.60 begins to execute green revolution, to 80 time commissariat came true first self-sufficient.

物产丰富，农业和服务业为印度最大的经济部门，主要粮食作物为水稻和小麦；主要经济作物有黄麻、茶叶、甘蔗、油菜籽和棉花；牛、山羊、绵羊、水牛饲养量居世界第一。60年代初印度开始实行绿色革命，到80年代初实现了粮食自给。

It is not grass, which is Polygonaceae, people familiar with the "Polygonum multiflorum, rhubarb", and so are blood brothers, is an international FAO recognized outstanding use of food-grain species, is China's fresh-a typical manifestation of cultural identity.

它不属禾本科，而属蓼科，与人们所熟悉的&何首乌、大黄&等是亲兄弟，是国际粮农组织公认的优秀粮药兼用粮种，是我国药食同源文化的典型体现。

The site covers how to identify presolar grains, what type of presolar grains are known, how they are studied and what we can learn from them. Also included is a presolar grain links page.

该网页介绍了粒子的确定、粒子的类型、我们如何来研究它们、以及我们可以通过它们获得什么样的信息等。

The Y-TZP nanoceramics with an average grain size of 60 nm and a relative density of 98% were prepared by pressureless sintering.

采用无压烧结获得了相对密度为98%、平均晶粒尺寸为60nm的Y-TZP纳米陶瓷。Y-TZP纳米陶瓷的显微硬度主要取决于陶瓷的相对密度、相结构和晶粒尺寸，即陶瓷的四方相质量分数越高，相对密度越大，晶粒尺寸越小，则显微硬度越高。
