A new type of dual-channel PAM chlorophyll fluorometer has been developed, which is specialised in the detection of extremely small differences in photosynthetic activity in algae or thylakoids suspensions.

设计了一种用于检测藻液或类囊体悬浮液光合活性微小差别的新型双通道PAM叶绿素荧光仪。

A data acquisition and data analysis software for the fast fluorscence kinetics fluorometer of our laboratory is redesigned and recompiled using assembly and BASIC language. The data acquisition rate in the fast rising part of the fluorescence kinetics curves is one order faster (100μs/point) than the old one. It can measure fluorescence parameters, such as Fo and Fi more accurately for calculation of the relative content of inactive PSⅡ, etc.

用N80-BASIC语言结合汇编语言重新编写了本室快速叶绿素动力学荧光计的测控程序，使快速荧光上升曲线的采样速度提高了一个数量级（达到100μs／点），可对Fo、Fi等关键荧光参数进行精确测定，为无活性PS Ⅱ中心相对含量的准确测定奠定了基础。

To study the foxtail millet variations in the chlorophyll contents, soluble protein contents, SOD, CAT activities and MDA contents of the leaves of two foxtail millet varieties, 05-61 and Jilgu 3 from flowering to maturing.

以谷子品种'05-61'和'金谷3号'为材料，研究不同基因型谷子开花至成熟期叶片的叶绿素含量、酶促防御系统的保护酶SOD、CAT活性和MDA积累量的动态变化规律。

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈"肥皂盒"形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

The result go as follows on citric acid-Fe,EDTA-Fe and N-Fe correcting apple(cv:Starking Delicious)chlorosis by root-inserted.All of the three iron fertilizersignificantly increased the content of chlorophyll and iron in leaves.

用不同浓度的柠檬酸-Fe、EDTA-Fe和自制的N-Fe对红星苹果缺铁黄叶病树根系输液结果表明，三种铁肥都显著增加了叶片中叶绿素和铁的含量，以5.99×10-3mol/LN-Fe处理效果最好，EDTA-Fe最敏感。

核心成份：采用S.O.S紧急救援抗痘模式的PH4酸性加强配方，萃取天然草本植物活性止痘剂，天然莓多酚、苦瓜素、青竹、叶绿素、蜂胶、大黄、橄榄、黄莲、昆布、茶树、芦荟、甘草、水杨酸、等成份。

Basesd on the precipitation difference in Tsaidam Basin of Qinghai Province, three sampling areas, including Geremu, Delinghan and Doulan, were selected, and then three sapmling plots in each sampling area were selected to study the characteristics of plant community which dominated by Ceratoides lateens, Nitraria tangutorum, Tamarix chinensis, Kalidium gracile, Haloxylon ammodendron and Salsola arbuscula respectively. At the same time, the morphological and physiological features of above-mentioned 6 species were measured for probing their drought tolerance. By using the subordinative function method, grey correlative degree analyse and no-weight index comprehensive evaluation method, their drought tolerance were compared as well. The results were showed as follows: The main xeric vegetation types in the desert steppe of Tsaidam Basin were Nitraria tangutorum community, Tamarix chinensis community, Haloxylon ammodendron community, Kalidium gracile+Salsola arbuscula community, Ceratoides lateens+ Haloxylon ammodendron+Kalidium gracile community.

根据青海省柴达木盆地不同地区历年降水量差异，在研究区内选择格尔木、德令哈、都兰3个采样区，每个样区内确定3个采样点(表示为D11、D12、D13、D21、D22、D23、D31、D32、D33)，以样区内唐古特白刺、甘蒙柽柳、梭梭、木本猪毛菜、里海盐爪爪、驼绒藜等6种主要植物为研究对象，通过调查采样地区群落特征，观测植物形态解剖特征，测定植物脯氨酸、可溶性糖、叶绿素、超氧化物歧化酶、过氧化物酶和过氧化氢酶等生理指标，研究了柴达木盆地6种植物抗旱生理特性及抗旱特性，用模糊数学隶属函数法、灰色关联分析和非加权指数评价法分别对6种植物的各个抗旱性指标进行了综合评价。

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.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
