If they were initially thwarted by allegedly indestructible siding made of aluminum, vinyl, or the maintenance-free, portland-cement-cellulose-fiber clapboards known as Hardie planks, they merely have to wait a century before most of it is lying on the ground.

如果它们最初被阻挡在所谓的坚不可摧的墙板外面——这种墙板由铝、乙烯化合物构成，也可能由被称为"高能厚壁板"、无需保养的硅酸盐水泥纤维隔板构成——它们所要做的不过是等上一个世纪，那么大部分的人工材料都会不攻自破了。

The Poly Vinylidene Fluoridemembrane was chosen to produce ultrasonic in transducer due to its higher sensitivity and better flexibility than other piezoelectric material.At the mean time,harmonic analysis to the PVDF film vibration was performed using ANSYS.The results show that the PVDF membrane can produce an ultrasound with afixed resonance frequency.

对各种压电材料进行比较分析，得到聚偏二氟乙烯膜比其它材料具有更高灵敏度和更好柔韧*，通过对其振动特*进行有限元分析，得到PVDF膜在固定频率具有振幅最大值，可知PVDF膜更适合做声频定向超声波传感器的振动膜来进行声音传播的方向控制。

It employs carbon dioxide as carbon source to replace traditional sugar, the concentration is controlled to be 2000- 3000ppm, takes light transmission, ventilating and water- proof fluoroethylene resin film as container, and gets tissue culture sprout and replanting sprout of chrysanthemum, which are characterized by largest plant height, largest leaf number, root number, longest root length and largest dry net weight of haulm and root, high rate of emergence and little pollution rate.

本发明提供了一种无糖培养菊花的方法，采用二氧化碳作为碳源，替代传统的糖，控制释放浓度为2000～3000ppm，采用透光性好、透气不透水的氟乙烯树脂膜为容器，在此种培养条件下，不同品种的菊花组培苗和组培后移栽苗在株高、叶数、根数、最大根长、茎叶部分和根部部分的干鲜重最大，出苗率高，污染率最低。

OBJECTIVE: To observe the hemostasis effect of PVF sponge.

The dissection of EtIe1 gene functions will be helpful to understand the molecular regulation of ethyele signal transduction in Hevea brasiliensis

对该基因功能的解析及深入研究，将有助于我们了解乙烯利刺激橡胶树信号转导的分子调控。

Four kinds of endogenous phytohormones in latex of Hevea brasiliensis were tested by using PGRIA and Gaseous Chromatogram.

采用酶联免疫检测技术和气相色谱法测定了巴西橡胶树胶乳中生长素、细胞分裂素、脱落酸和乙烯等4种植物生长物质的含量。

The SHS was carried out using NaN3 as a reducer; and poly (C2F4), hexachloroethane (C2Cl6) and hexachlorobenzene (C6Cl6) as three various oxidizers.

采用还原剂NaN3和三种不同氧化剂－聚四氟乙烯、六氯乙烷和六氯苯，实施了SHS制备。

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.

这是凯特，那个是爱朗。
