Based on five-year different protected and common cultivation field experiments and by using Oringin and SAS software intergraded with the principles of bio-mechanism, dynamic models of leaf age development and leaf area index change of potato were submitted. The simulated results showed that the methodology was of easy usage, clear mechanism and high accuracy.

The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0～700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.

In the dynamics of total litterfall and litterfall components, there were seasonal variations and leaf was the basis. Nutrient content of most elements and litterfall have alike variational trends. Above-mentioned results exhibited that leaf had the conclusive influence on total litterfall and nutrient content.

总枯落量与枯落物各组成分均有季节性变动，且皆以枯落叶为主(70-75%)，而枯落叶与枯落物内多数元素的养分含量与其总枯落量有相似的变动趋势，以上结果显示枯落叶对总枯落量及养分含量有决定性的影响力。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
