Dendrimers have drawn lots of attention because of their highly branched structures capable of being used in photochemistry .

树枝形聚合物由于其特殊结构所表现出来的性质在光化学中有着广泛的应用前景，近20年来，树枝形聚合物在光化学中的研究也取得了很大的进展。

The nutrient absorption in fruits were lower than other fruits,especially,the amount of phosphorus and calcium in fruits were only one eighth of Satsuma mandarin.It is one of the nutrient physiology characteristic in Chinese bayberry that the amount of absorbed phosphorus in whole tree,and phosphorus,calcium in fruit are rather lower.

幼年树和成年树P吸收量分别为0.37 kg和0.9 kg，占全量的2.7%和2.3%，其吸收量和吸收比例均较低；果实养分吸收量与其它果树相比，相对较低，尤其是P2O5和CaO的吸收仅为温州蜜柑类的1/8，认为杨梅树体P、果实P和Ca吸收量低是杨梅营养生理的特性之一。

Minimal Cut Sets are separated from the reduced Fault Tree built by module and Faunet arithmetic.

用故障树最小割集诊断法诊断装备系统故障，以Faunet算法和模块化构建并简化故障树、求解其最小割集。

The directory service failed to lock a tree in preparation for a tree deletion because the tree was in use.

因为目录树在使用中，目录服务未能为删除目录树而将其锁定。

The consensus tree by ITS gene sequences indicated that subgenus Cerasus was basal to the other subgenera with a bootstrap value of 68% and occupied an isolated position.

基于ITs序列得到系统发育树为樱类位于系统发育树的基部，构成一单系分支，其内部支持率为68％。

According to molecular,we can vested them in Agaricomycetidae,Agaricales. The effects of temperature, nutriments, illumination and other factors on the germination of the spores of Lasiosphaera fenzliiand Calvatia gigantea were firstly studied in this paper.

利用rDNA ITS序列进行分析并建构系统发育树，结果表明了脱皮马勃Lasiosphaera fenzlii和大秃马勃Calvatia gigantea的亲缘关系较近，根据分子系统发育进化树可将其归属伞菌亚纲、伞菌目。

Room service: A red-knobbed hornbill arrives with breakfast, which he will regurgitate for his roughly three-month-old chick safely inside a nest hole in an Alstonia tree. Though its mother has left the confines of the nest, the chick remains within for another few weeks, dependent on its parents until it fledges.

房间服务：一只红冠犀鸟携早餐而来，它会将食物反刍，以喂养其安然处于灯架树树洞中的三个月大的雏鸟即便母亲离开了鸟巢的区域，雏鸟仍要里面待上几周，依赖它们的父母直到羽翼渐丰

The tree T=is a bichromatic tree subgraph in a maximal plannar graph G, in which the subgraph induced by V_t is a tree and T is a component of some bichromatic subgraph Gij of some 4-coloring of G.

极大平面图G=中的一个二色树子图T=，其Vt在G中导出子图为树，并且图G存在至少一个四着色C，使T是该四着色一个二色子图的一个连通支。

Seedlings of one-year-old Broussonetia papyrifera L. were subjected to the drought stress of soil under different moisture conditions. The injury degree of cell plasma membrane and the correlative enzyme activity of plasma-membre protection system in the leaves of the seedlings were studied. Their relative conductivity, MDA content and activities of superoxide dismutase, catalase and peroxidase were measured.

以盆栽当年生构树幼苗为实验材料，研究不同程度土壤干旱胁迫下及复水之后构树叶片细胞质膜的伤害程度、丙二醛含量和其酶促抗氧化保护系统（超氧化物歧化酶SOD、过氧化氢酶CAT和过氧化物酶POD）的活性。

The 28S rDNA molecular phylogenetic trees showed: 1 entoprocts and phylactolaemate ectoprocts constituted a sister group, strenghthening the opinion that entoprocts should be reunited into phylum Bryozoa; 2 the cheilostome gymnolaemates was obviously non-monophyletic; 3 bryozoans itself was polyphyletic beyond any doubt, its main lineages were scattered in different positions of the lophotrochozoan trees; 4 to our great interests, the phylogenetic position of cheilostomes was between the diploblastic and the triploblastic, indicating they may play an important role during the evolution route from the diplobastic to the triploblastic animals.

28S rDNA分子系统树显示，内肛动物和被唇类外肛动物聚在一起并互为姐妹群，支持将内肛动物重新归入苔藓动物门的结论；唇口目裸唇类外肛动物绝非单系发生；苔藓动物本身也不是单系发生的，其主要类群分别位于触手冠担轮动物系统树的不同位置，特别是，唇口目苔藓动物的系统地位介于二胚层动物和其它三胚层动物之间，可能是二胚层动物向三胚层动物演化过程中的一个关键类群。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
