There are greater differences between the absorbing dust、sulfur dioxide and heavy metal capability of different types of trees. Synthetically Considering the purification function on the air pollution of trees, can divide the trees into : The first kind of comprehensive absorbability to the air pollution is relatively strong, pagoda tree, Apple, China Savin, Poplar; Second comprehensive absorbability in air pollution strong, such as Deodar Cedar, purple leaf Li, Glossy Privet; The third kind of comprehensive absorbability to the air pollution is medium-sized, such as the cedar , Pear , Evergreen Euonymus , peach, apricot, Huashan pine.

综合考虑植物对环境的净化作用，可将试验段生态防护林带的组成树种分为三类：第一类对环境净化能力很强，如圆柏、国槐、杨树、苹果等；第二类对环境净化能力强，如雪松、大叶女贞、紫叶李等；第三类对环境净化能力中等，如华山松、梨、杏、桃、黄杨等。

In this chapter, we obtain the following conclusion: Let f=h+〓 be a univalent orientation-preserving harmonic mapping defined on the unit disk U such that f is convex in a direction and real on the real axis, and satisfies the normalization f (0)=0 and 〓, then f is typically real.

在这一章中，我们证明了如下事实：对于单位圆U上的单叶调和映照f=h+〓，如果它满足条件〓，且在其映照下单位圆的像域是一个方向凸的，则它必定是典型实照映射。

The research results also pointed out that the complex compound of iodine and amylum is not stable, and has a regular fadding process; the concentration of phosphate buffer solution has a serious inffluence on the fadding effect of the extractive solution of plant leaves.

取一定部位的功能叶，用打孔器取40个叶圆片，研磨加水后离心制得植物材料提取液，取一定量上清液加到3ml含有碘、叠氮化钠和淀粉试剂的反应混合液中，30秒后测定1分钟内吸光值的变化量。

In the first part,we give the inner radius of univalency for fan-shaped domains and for quadrilateral domains with vertexes on a circumference and sides forming the sequence abba .

在第一部分中，我们给出了扇形和四边为abba形式的圆内接四边形的单叶性内径，并给出了长方形区域单叶性内径的下界估计。

Extracts from 6 species of IPomoea batatas Lam leaves have been determined for their bacteriostatic effects on five types of pathogenetic bacteria (Escherichia coli,Bacillus subtilis, staphylococcus aureus, staphylococcus albus, and Proteus vulgaris) by using the methods of the filter paper disk test s and the dual-flat tests.

用滤纸圆片法和双层平板法测试六种不同品种红薯叶（SPGS—1，SPGS—2，SPGS－3，SPGC，SPRC，SPRS）的提取物对五种致病菌：大肠杆菌、枯草杆菌、金黄色葡萄球菌、白色葡萄球菌、普通变形杆菌的抑制作用、结果发现SPGS—1、SPGS—2、SPGS—3和SPRS四种红薯叶提取物有明显的抑菌作用，其最低抑制浓度范围为0.4g／ml～1·0g／ml

Leaves 1-foliolate, rarely 3-foliolate or simple; petiole usually articulated with base of leaf blade, usually conspicuously winged; leaf blade subleathery to leathery, with dense pellucid fragrant oil dots, margin crenulate or rarely entire.

叶单身复叶，单叶或很少掌状3小叶叶柄通常与叶片基部间有关节，通常明显具翅；叶片近革质到革质，具浓密透明芳香的油点，边缘具细圆齿或很少全缘。

Leaves opposite, subopposite, whorled, spiraled, or alternate, usually petiolate, estipulate; petiole sometimes persistent and thornlike; leaf blade simple, margin entire or subentire, sometimes toothed, glands often present between crenations of proximal margin and at base or on petiole.

叶对生，近对生，轮生，螺旋状排列，或者互生，通常具叶柄，无托叶；叶柄有时宿存并刺状；单叶，边缘全缘或者近全缘，有时具齿，通常在近端部和基部的圆锯齿之间或叶柄上有腺体。

The flower has calorie of power, sepal egg shape wraps around needle form, petaline corydalis is lubricious, have canaliculus state, straight or go up a bit curved; Florescence 4 ～ May, purple floret, xie Rengqing of after autumn bine is green be like first, the companion other the flower has acicular small fruit, till at the beginning of the winter, ground upside divides ability wither, because this is wonderful ground by the plant, but sheet is planted the predestined relationship issues a Zhi Yulin or on the meadow of exposed to the sun, also but with other herb, wait like bison grass, dandelion mix kind, form level ground of beautiful compose flowers and plants.

紫花地丁叶基生，狭披针形或卵状披针形，边缘具圆齿，叶柄具狭翅，托叶钻状三角形，有睫毛。花有卡柄，萼片卵状披针形，花瓣紫堇色，具细管状，直或稍上弯；花期4～5月，紫色小花，秋后茎叶仍青绿如初，花旁伴有针状小果，直至冬初，地上部分才枯萎，因此是极好的地被植物，可单种成片植于林缘下或向阳的草地上，也可与其他草本植物，如野牛草。蒲公英等混种，形成漂亮的缀花草坪。

At same time, the inverse-trapezium nectar scales, rectangular and spheral seed with high longitudinal ridge were also reported.

同时，首次报道了大叶火焰草倒梯形状的心皮鳞片，扫描电镜下大叶火焰草的种子呈近矩圆球形，外壁被高脊状纵棱。

The primary aim of this experment was to make clear the photosynthetic characteristics of eggplant.The photosynthetic charateristics of different varieties, nodes, growth and development stages and the effects of photo, CO2 concentration and temperature on Pn of own-rooted seedlings in eggplant;the photosynthetic charateristics of grafted seedlings that cions were grafted on rootstocks; the effects of low temperature(10/5 ,day/night) and poor light(60mol.m-2.s-1 and l20mol.m-2.s-1) on photosynthetic and other physiological characteristics of own-rooted seedlings in eggplant with four and five leaves were studed.

以茄子自根苗为试材，研究了不同品种、不同叶龄、不同叶位、不同生育期单个叶片的光合特性及环境因子对盛果期功能叶片Pn的影响；以托鲁巴姆、CRP为砧木，二苠茄和快圆茄做接穗所得的茄子嫁接苗为试材，研究了嫁接苗单个叶片光合特性及环境因子对嫁接苗功能叶片Pn的影响；以自根苗幼苗(4-5叶)为试材，研究了低温(10／5℃)弱光60μmol.m~(-2.s~(-1)和120μmol.m~(-2)。s~(-1)对茄子幼苗光合及其它生理特性的影响。

The split between the two groups can hardly be papered over.
