The results indicate that the best model for DNA evolution of rbcL sequences in Liliales is GTR+I+G, and the topology of Bayesian tree is similar to those of Maximum parsimonious tree and Neighbor Joining tree, but giving more resolution and higher support values.

结果显示，百合目rbcL基因最适合的DNA进化模型为GTR+I+G，贝叶斯法与距离法和最大简约法构建的系统发育树拓扑结构相似，没有显著差异，但是分辨率和支持率明显比后者高。

Hec limbed to the tree top, ate the apples, took a nap under the shadow...He loved the tree and the tree loved to play with him.

他会爬到树顶摘苹果吃，会在树荫下小憩……他很喜欢这棵树，树也很高兴和他一起玩耍。

本文把划分向量V当成一种特殊的数制，找出其进位规则，从而求得V/D和D/V数制转换。所建立的算法经计算机验证，是正确的。

From the base to the crown in axial, the vessel-elements proportion increases in fluctuation, contrary to the ray proportion. The fiber proportions in the regions of base and crown are less than that in the trunk of tree, and fluctuate at 65% or so. The parenchym proportion increases quickly to the 1.3m height of tree, reaching the maximum at 9.52%, and then decreases quickly to the 3.3m height of tree (8.90%); afterward it leveled off and increases slightly.

组织比量轴向变异表现为随树高增加导管比量波动性递增，与木射线比量相反；纤维比量在近根区和近冠区稍小，而主干部稍大，并在65%左右波动；轴向薄壁细胞比量先随树高增加急剧增加，到1.3m树高处达最大值（9.52%）后又急剧降低至3.3m树高处的8.90%，以后基本稳定并在波动中略有增加。

The phytotoxin can restrain the activities of peroxidase , polyphenol oxidase and phenylalanine ammonia lyase that existed in the tree, and so reduce the resistance of the host tree and benefit the fungus to intrude into the tree successfully.

该毒素能抑制寄主组织中过氧化物酶、多酚氧化酶和苯丙氨酸解氨酶的活性，降低寄主树木的抗御能力，从而有利于菌突破寄主的生理防御屏障而成功地侵染生长。

Hu Diequan Park,"Tip-chuen, is the beauty of the green, wood-jun and love is zoned" environment placard, this remark is not false to say Hu Diequan of the United States, not only benefited from the way we see Fengwei Bamboo, Gadao amenities such as the Christmas tree to plant new trees and the pine-chuen, after Manshanbianye, Berlin, palm forests, tea-lam, rhododendron forest, Mao bamboo, also benefited from more Hudiequanbian Acacia trees, acid-tree, Chinese pistache , And other local tree species unique aroma.

最后说&树&。蝴蝶泉公园内，有&蝶泉之美在于绿，请君爱护划和木&的环境标语牌，这句话一点不虚假地说出蝴蝶泉之美，不仅得益于沿途我们所见到的凤尾竹、圣诞树等夹道迎客的新栽林木，以及泉后满山遍野的松林、柏林、棕榈林、茶林、杜鹃林、毛竹林，还更得益于蝴蝶泉边合欢树、酸香树、黄连木等本地特有的芳香树种。

By analyzing soil quality of 4 kinds of land use types in Kalamay agriculture development area according to principal component analysis, we draw the conclusions: nature shrub tree land is affected little by mankind, a great deal of organic matter return to soil every year, and root system can improve soil physical quality, can absorb salt from soil, so the soil quality of nature shrub tree land is the best; the soil quality of farmland is better than the soil quality of manpower Tamarix Bulrush land, which may be reasoned that man make for soil quality by irrigation to exclude salt and fertilizing organic muck in the earlier oasis digging up period. Soil physical qualities of tree land get harden and worsen for flooding irrigation, furthermore climate in Kalamay is dry and rainless , the other irrigation is very long time after the former one, so soil get harden severity and result soil physical quality get worse and worse.

利用主成分分析法分析新疆克拉玛依农业开发区四种土地利用方式下的土壤质量，得出：天然灌木林地，受人为影响较小，每年有大量有机物质返还土壤，且天然灌木的根系可以很好的改良土壤的物理性质，同时所选天然灌木林灌木多是耐盐碱并且本身又具有吸收积累来自土壤的盐分，土壤质量最好；农田受到的人为影响最大，但农田综合得分却好于人工柽柳芦苇地综合得分，这可能是由于在开垦初期的绿洲农田，受到了人们灌水压盐及增施各种有机无机肥料等有利于土壤质量提高的措施所致；乔木林地，由于人们用大水漫灌的方式灌溉，致使林地土壤变得板结，土壤物理性质下降，加上克拉玛依地区气候干燥少雨，一次灌溉后较长时间后才有下一次灌溉，致使土壤理化性质恶化，土壤质量不高。

In this paper,the character of the user behaviors in the Operating System and the formal de- scription are analyzed firstly,a insider user behavior monitoring model based on the user behavior tree is put forward, which can acquire the"open authorization"behavior traces by the OS behavior-tree,and make use of the user behavior- tree hierarchy to monitor the inside user behaviors.

首先分析了操作系统中用户行为的特征及其描述方法，提出了一种基于用户行为树的用户行为监管模型，依据操作系统行为树来分析用户在操作系统中可能存在的&开域授权&行为踪迹，然后根据用户行为的层次性来实现对用户行为的监管。
