The clear water that day of the 2-3 that irrigate air wants when watering is advisable, and when watering, should irrigate in plant ' cup ' in shape, in irrigating the matrix in flowerpot directly, even if slant in the matrix inside the basin dry, xie Beizhong has the word of water, plant still grows good, but if be the humidity in basin earth only big, and Xie Beizhong is anhydrous a plant is lacklustre, occurrence leaf easy hair is yellow wait for harmful response.

浇水时要浇晾2-3天的清水为宜，且浇水时要浇在植株的'杯'状中，不要直接浇在花盆的基质中，即使是盆内基质中偏干，叶杯中有水的话，植株依然生长良好，但假如只是盆土中湿度大，而叶杯中无水则植株无生气，出现叶子易发黄等不良反应。

This article is based on the material balance equation and the no fixed water inroad equation,educe the equation of the no water recovery and the water coming time.

Carbon-14 through the ring inference and reference "polar glaciers source of water theory" on its equivalent billion years of age, and the 2004 Antarctic expedition of 3000 meters from the polar ice-class source of water similar to the water is clean functional effectiveness can not Bacteria, naturally full of "active" role in the trend of high-Tour-organic marine biological activity of the best deep water, natural "green" Need for Water, high value-added applications, will become the 21st century "Water for Life" the new mainstream !

通过碳14的年轮推断和参考《极地冰川源水理论》它相当于上亿年的年龄，与2004年南极科考抽取的3000米极地冰川级源水类似，其水功能功效能是洁净无菌，充满自然"活性"作用的游离子有机态势高生物活性的海洋深层水的极品，自然"绿色"之水极品，极高的应用附加价值，将成为21世纪"生命之水"的新主流！

Through the thermodynamic calculation of the reaction that aluminum and magnesium reduce anhydrous scandium chloride molten salt to prepare aluminium-magnesium-scandium master alloy, we got that the standard equilibrium constant of the reaction is 1.074 ×10~(19), and the experimental equilibrium constant of it is approximately 6.874 × 10~(14)under around 1200 K and 1 standard pressure, which demonstrate that the reaction can take place and proceed thoroughly.
