Here we show that range-expanding plant species from a riverine area were better defended against shoot and root enemies than were related native plant species growing in the same area.

当前的气候变暖阶段正在导致一些植物和动物的生存范围从较低的纬度和高度向较高的纬度和高度迁移。

In order to better understand the determinants of tree height limit,32 tall tree species such as Parashorea chinensis,Sapium baccatum,Garcinia cowa,Eucalyptus citriodora,E.grandis×E.urophylla,Albizia falcataria,Populus tomentosa,Platanus hispanica,Ginkgo biloba,Pinus tabulaeformis,Ulmus pumia,Salix gordeivii,and Elaeagnus angustifolia from typical environments such as Xishuangbanna rainforest,Guangzhou subtropical area,Zhengzhou,Beijing,Helanshan mountain and Maowusu sandland in China were studied.

为了更好地了解树高极限的限制因素，本文对全国典型水分分布区域西双版纳、广州、郑州、北京、贺兰山和毛乌素沙地等地区生长的望天树、浆果乌桕、小叶藤黄、柠檬桉、巨尾桉、南洋楹、毛白杨、悬铃木、银杏、油松、榆树、沙枣、小黄柳等32种较高的木本植物进行了研究。

The result shows that when ColE7 is bound to its prefer sequence, the DNA main chain was distorted the most and the scissile phosphate was located closer to the endonuclease active site, thus leading to a more efficient cleavage.

分析ColE7与DNA的复合晶体结构后发现，当ColE7与其偏好的序做结合时，其DNA主链的构型有相当明显的变化，且scissile phosphate较靠近活性中心区，可能因此导致较高的活性。

The higher the concentration of manganese sulphamate in the electroforming electrolyte, and the lower the tem- perature of the electrolyte, the more manganese content is in the layers.

在复杂形状零件进行Ni—Mn合金电铸时，选择较低的电解液锰盐浓度、较高的电解液温度和合适的脉冲电流脉宽等工艺条件，有利于改善电铸层锰含量分布的均匀性。

But at relatively high temperatures, the alloy exhibits complete superelastic characteristics, and only one-step martensitic transformation is observed.

在较低的形变温度下，沿单晶母相［001］方向的压应力诱发的是两步马氏体相变，材料表现出赝弹性；在较高的形变温度下，只能观察到一步马氏体相变，材料展现出完全超弹性特性。

Synthetic ettringite precipitated from solution shows a highly positive zeta potential, hence it adsorbs great amount of negatively charged superplasticizer. Monosulfate has only a slightly positive zeta potential and adsorbs smaller amounts of superplasticizer. For syngenite, portlandite and gypsum, the zeta potential is around zero or negative.

以溶液沉淀析出法人工合成的AF具有较高的正zeta电位，能吸附大量带负电荷的超塑化剂，AF仅带少量正电荷，其吸附超塑化剂相对较少，钾长石、氮氧钙石和石青的zeta电位几乎为零或负值，因而基本不吸附超塑化剂。

ITS2(Intemal Transcribed Spacer 2) region in ribosome DNA has a character of conservative that makes a low aberrance ratio, on the other side, ITS-2 region evolves itself. According to the characters, ITS-2 region sequencing is an effective parameter in taxology and pests-control..

核糖体基因的第二内转录间隔区有较高的保守特性，同时进化速度又较快，因此序列进行测序得出的种内差异，是系统发育学的有力参数，也有助于异色瓢虫分类学和农林虫害的防治。

Terral research scientists are developing hybrid corn with stacked biotechnology traits that will give producers the ability to produce higher yields, while being more friendly to the environment by using less herbicides and pesticides.

terral研究的科学家正在开发杂交玉米与堆叠性状的生物技术将会给生产者的能力，产生较高的收益率，而更友好的环境，用较少除草剂和杀虫剂。

Since the element sulfur has lower electro-negativity than oxygen and the C=S double bond is easier to be polarized than C=O double bond, thiocarbonyl compounds and carbonyl compounds have different reaction properties, and their photochemical reaction mechanisms often possess dramatic difference.

但是，由于硫元素较低的电负性和C=S双键较高的可极化性，硫代羰基化合物和羰基化合物有着本质不同的反应特性，光化学反应机理常常存在着戏剧性的差别。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
