The results indicated the following: 1 All of the root, stem, leaf and bud of Ambrosia trifida have higher biosorption capability for Cu~(2+).

本论文获得的主要结论为： 1三裂叶豚草的根、茎、叶、花蕾四个部位对Cu~(2+)具有较强的吸附作用，且吸附能力的顺序为叶＞花蕾＞茎＞根。

Moreover, certain photoreceptors in the compound eyes of this taxon react with GABA and 5-HT antiserum.

在整个脑区，视叶、触角叶和蕈形体冠三个神经纤维网对 5-HT 抗血清的反应最弱，几乎不被 5-HT 抗血清所标记。

It indicates that the different parts of the cattle-egg stone samples in different colours all mainly compose of pyrophyllite, coexisted by two kinds of polytype of monoclinic and triclinic pyrophyllite, and the average crystal structural formula is Al4.04 Si7.89 Al0.11O204. The aggregation of pyrophyllite arranges with no direction, and the crystal size of the single pyrophyllite crystal in the weathering skin is a little bigger than that in the basal part.

结果表明，不同颜色牛蛋石样品的不同部位皆以叶腊石为主要成分，并以叶腊石的单斜和三斜两种多型共存，其平均晶体结构化学式为Al4.04[Si7.89Al0.11O20]4；其叶腊石集合体呈无定向排列，风化皮中叶腊石单晶的粒度略大于基体中的。

By analyzing the tissue-specific expression in 35-day-old plants, AtMAPR2 was expressed higher in flower, rosette leaf, and silique; while AtMAPR3 was expressed higher in flowers, roots, rosette leaf; AtMAPR4 and AtMAPR5 were expressed higher in flowers.

而三十五天的器官特异性分析，可观察到AtMAPR2对花、丛生叶与长角果；AtMAPR3对花、根、丛生叶；AtMAPR4、AtMAPR5对花具有器官特异性。

The length,width,thickness and weight of the current year and more than one-year-old needles of both bi-needle-cluster and tri-needle-cluster of slash pine were measured to expose the differences in terms of leaf shape and specific leaf area,and leaf area index was estimate based on measurement of the plantation in Qianyanzhou Ecological Station.

对湿地松当年生和多年生两针一束、三针一束叶片的长度、宽度、厚度和重量分别进行量测，据此探讨不同类型叶片的叶形和比叶面积差异，并结合样地调查数据对中科院千烟洲试验站湿地松人工林的叶面积指数进行计算。

The influence of tailboard on the exit flow fields of compressor cascades with normal straight, positive and negative curved blades were investigated at zero incidence.

进行了带尾板的常规直叶片、正弯曲叶片、反弯曲叶片组成的三种矩型压气机叶栅在低速风洞上的实验研究，测量了叶栅出口流场，分析了零冲角下尾板对叶栅出口能量损失分布情况和二次流速度矢量的影响。

Carbonyl arsonium ylides, which reacted with almost equimolarphenylselanyl iodide, were conversed into α-phenylseleno arsonium ylides in thepresence of triethylamine, affording a new method for the synthesis of α-phenylseleno arsonium ylides.

在弱碱三乙胺存在下半时，稳定的α-羰基胂叶立德和几乎等摩尔量的苯硒基碘作用，转化成α-苯硒基胂叶立德。提供了一个合成α-苯硒基胂叶立德的新方法。

This fibreglass fan made up of three giant blades, each blade looking like a giant windsurfer and weighing 5.6 tons, the diameter of the entire fan reaching 70 metres.

这面由玻璃钢制作的大风扇由三片巨大的螺旋桨叶组成，每扇桨叶都像一面巨大的帆板，桨叶重5.6吨，整个大风扇的扇面直径达70米。

At present, most hydropower plants close the wicket gate by using the closing law with two or three slopes. In fact, as the unit capacity goes up and the turbine working range of water head be even wider than before, so that the fixed closing law with two or three slopes can't control the unit stability effectively when the big fluctuation transient comes op.

目前，普遍采用导叶两段或三段关闭规律，实践表明，随着水轮发电机组容量的增大和水轮机工作水头范围的增大，这种固定的两段或三段导叶关闭方式不能有效地控制机组在大波动水力过渡过程中的稳定性。

In order to resolve the curing technology of loose tobacco curing barn, and spreading it in most tobacco planting area, the series of research of curing capability, technology of loading and curing technology on loose tobacco curing barn were studied. We found out the curing technology of loose tobacco curing barn when adopting nature loading method, the loading density were 75-85kg/m3, and the thermometer were hanged at the bottom layer. This technology was on the base of its own characteristic, it also integrated the technology of the three stage curing technique, and it had the virtue of simplicity of operation, earthliness and understandability, better curing effects, and preferably spreading foreground.

为解决散叶烤房烘烤工艺难题，使其能在广大烟区快速推广，通过对该烤房烘烤性能、装炕技术和烘烤工艺的系列研究，提出了采用自然堆积法装烟，装烟密度75~85kg/m3，温度计挂在一层时的散叶烤房烘烤技术，该技术根据散叶烤房自身的特点并结合&三段式烘烤工艺&，操作简单，通俗易懂，易于被烟农掌握，烘烤效果较好，有较好的推广应用前景。
