Zn~(2+) had a relative lower toxic effect on the conchocelis among the five heavy metal ions in this experiment, when the concentration was up to 60μmol/L and time was after 48 hours, its slightly negative effect on the conchocelis came into effect, chlorophyll a content, soluble protein content, mannite content, POD activity started to decrease and MDA content began to increase.

Zn~(2+)在实验所采用的五种重金属离子中毒性较弱，对藻体造成的抑制影响较小，当浓度升至3.9mg/L、时间加长到48h时出现极微的抑制作用，叶绿素a含量、可溶性蛋白含量、甘露醇含量、POD活性下降，丙二醛含量升高。

The biochemical and physiological effects of Pb~(2+) on conchocelis of Porphyra yezoensis was lower relatively, at the beginning, the algae still grew under the condition of higher concentration-40 mg/L, mannite content and POD activity appeared a tendency to first increased and then decreased, but chlorophyll a content declined slightly, on the contrary, MDA content went up quickly.

Pb~(2+)对条斑紫菜丝状体的毒性相对较弱，在浓度40 mg/L时，处理早期(12h时)丝状体仍有生长，此浓度下藻体的甘露醇含量和POD活性均随处理时间的延长呈现先升后降的趋势，而叶绿素a含量逐渐下降，与此相反，丙二醛含量迅速上升。

This paper takes conchocelis of Porphyra yezoensis as experiment material, analyzes the toxicity of heavy metal ions on 6 parameters of chlorophyll a content, soluble protein content, mannite content, peroxidase activity, malonaldehyde content and the growth of conchocelis. In experimental conditions, samples were exposed to mercuryHg~(2+, copperCu~(2+, cadmium Cd~(2+, plumbumPb~(2+ and zincZn~(2+ at different concentrations and were taken after exposure for different hours.

本文以条斑紫菜丝状体为实验材料，测定条斑紫菜丝状体中叶绿素a含量、可溶性蛋白含量、甘露醇含量、过氧化物酶活性、丙二醛含量及藻体生长情况6项生理生化指标，研究分析了不同处理浓度和不同培养时间下重金属离子Hg~(2+)、Cu~(2+)、Cd~(2+)、Pb~(2+)、Zn~(2+)对条斑紫菜丝状体的毒性效应。

The extraction and isolation conditions of chlorophyll were studied using the leaves of Indocalamus herklotsii McClure with supercritical CO2 extraction.

采用超临界CO2萃取技术，研究了从箬竹叶中提取叶绿素的工艺。

The obvious characters are Chlorophyll-a concentration increased (The Chla concentration even reach hundreds milligramme per stere in serious area), transparence and dissolving oxygen reduced.

三峡库区蓄水后，由于水文条件发生明显改变，次级河流出现大面积富营养化现象，其显著特征就是藻类疯长引起水体Chla含量增加(在严重的累积区Chla浓度高达数百毫克/立方米)而透明度、溶解氧降低。

The results showed that there were remarkable seasonal variations of chlorophyll a concentrations and grain size at the surface of the mudflat, i.

结果表明，研究区域表层沉积物中叶绿素a的浓度4，5月份较高，分别为(5.997±0.803)gg^(-1)和(2.356±0.295)gg^(-1)，12月份最低，为(0.571±0.091)gg^(-1)；表层沉积物中细颗粒物质(0m)含量从4月到12月也有减少的趋势，春季4月份最高，为(91.0±5.44)%，冬季12月份最低，为(59.8±11.95)%。

Fatsia japonica、 Nandina domestica、 Laurus nobilisl、 Hhypericum Chinense were cultivated under four different light regimes(fully open site,58%,24% and 6% daylight).Their leaf area, leaf mass per unit area, the gas exchange parameters , chlorophyll content, the RPP were measured.

测定了4种光强(100％、58％、24％、6％自然光强)下，地被植物八角金盘、南天竹、月桂、金丝桃的叶面积、叶片气体交换参数、比叶重、叶绿素含量和高温下细胞质膜透性。

For example red autumnal leaves is bright red broadleaf plant, red the flowers observing a part of a historical period such as back laurel, contain cyanine element inside their mesophyll cell, consequently the front of blade or the reverse side present red; The lamina that wait is in Gong Sang, nandina synthesis of the chlorophyll below weak light is much, kind of carotene falls in strong

例如红叶朱蕉。红背桂等观叶花卉，在它们的叶肉细胞内都含有花青素，因而叶片的正面或背面呈现红色；红桑。南天竹等的叶片在弱光下叶绿素合成多，在强光下类胡萝卜素合成多，故放在半阴处培养叶色发绿，放在强光下养护，则叶色发橙；金边吊兰。金边虎皮兰叶片的不同部位上细胞内分别含有叶绿素和叶黄素，所以叶片呈现出黄绿相间的两种颜色。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
