The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species (r=0.93, p.01). Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher P T and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

这些结果表明，所观测的早春短命植物具有典型的C3植物特征，相比其它类型的荒漠植物具有较高的单位叶面积P高T及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。

这些结果表明，所观测的早春短命植物具有典型的G植物特征，相比其它类型的荒漠植物具有较高的单位叶面积Pn、高Tr及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。

These improvements included, widening and re-paving the footways with York Tone buff coloured paving. Replacing and reorganising the street furniture into one neat line behind the kerb to leave an unobstructed walkway for pedestrians. Relocating telephone booths to the sidestreets. Closing off selected sidestreets to provide a more continuous footway enhancing pedestrian safety and preventing restricted traffic from entering the street. Erecting new, dual purpose lighting covering both the carriageway and footway from one post. The posts also included attachments enabling banners to be put up. Creating bus lay-bys….

这些改进包括很多方面：拓宽并用浅黄的约克色调重铺人行道；重新组织摆放街边摆设，使砌边石后面的街道干净整洁，以便给行人留出无障碍物的通道；把电话亭挪进小巷安置；有选择地封闭一些小巷，从而提供一条更连贯的人行道，既保障了行人的安全，也避免了一些受限制的车辆进入大街；建立新的双重目的的照明系统，从一根电线杆上瑶同时照射车道和人行道，这些电线杆上还要有能安置旗帜横幅的连接物；修建公共汽车的路边停车处，等等。

Fruticosa grown in clay sandy soil and clay soil was best, and they were significantly higher than that in other soils from 12th d in the test. The biomass of hypocotyls in 4 soils was similar, and that in forest soil was higher and its dry weight accumulated in hillside soil was more.

沙土和黏土中紫穗槐根的生物量最好，并在第12天的时候开始就明显高于其他土壤。4种土壤中的下胚轴生物量都差不多，以森林土的较高，而山坡土的积累的干重较多。

Turfgrass seeds of nineteen varieties were treated with the different Pb2+ concentrations of 0, 200, 400, 600mg/L, and germination potential, germination rate, root length, shoot length, fresh weight, chlorophyll content, MDA content of seedlings were determined to compare theirs lead tolerance.

用浓度分别为0、200、400、600mg/L的Pb2+分别处理19个品种草坪草的种子，测定了供试种子发芽势、发芽率、幼苗根长、苗长、鲜重、叶绿素含量、丙二醛含量等7项指标，比较19个品种草坪草生长初期耐铅性的强弱。

The result showed that mycorrhiza inoculation was beneficial to the conifers,the volume weight of the medium and the contents of P,soluble P were major factors influencing seedling growth.

结果表明：菌根接种对培育针叶树容器苗非常有利。基质的容重、全磷和速效磷的含量是影响油松容器苗生长的主要因子。

This old man, he played eight, He played knick-knack on my plate; With a knick-knack paddywhack, Give a dog a bone, This old man came rolling home.

与小玩意儿，稻重击，给狗一根骨头；这个老人回家了辗压。这个老人，他演奏了十；他'再次'演奏了小玩意儿(或'在我的笔'，'在我走路'或'在我的母鸡')。

This old man, he played two, He played knick-knack on my shoe; With a knick-knack paddywhack, Give a dog a bone, This old man came rolling home.

与小玩意儿，稻重击，给狗一根骨头；这个老人回家了辗压。这个老人，他演奏了三；他演奏了小玩意儿'在我的膝盖'。

This old man, he played seven, He played knick-knack up to Heaven; With a knick-knack paddywhack, Give a dog a bone, This old man came rolling home.

Average weight of single fruit and yield per 667 m2 of grafted melon were higher than the own-root melons.

嫁接植株的增产效果显著，其平均单瓜重和667m2产量均高于自根植株。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
