地力维护措施可在很大程度上防治连栽人工林生物量和土壤有机碳贮量的下降，2代杉阔混交林生物量和土壤有机碳贮量分别比2代纯林提高69%和19%；2代按树与相思属树种的混交林生物量比2代按树纯林增加29%；施肥可使2代杉木人工林生物量提高22%。

Lines which were 2n=21"+1" and one line which was 2n=20"+2", one line which was 2n=43. The salt-resistance addition line Line15 was confirmed as a Disomic alien addition line by C-banding, SSR, FISH methods, and the two alien addition chromosomes had close correlation with the long arm of the second homoeologous group, the centromere region of the third homoeologous group and the short arm of the seventh homoeologous group. We also confirmed the particular C-banding type of the alien addition chromosomes by C-banding following FISH method. The drought-resistance addition line Line17 was found also as a Disomic alien addition line by SSR and FISH detection. The alien addition chromosomes had close correlation with the short arm of the second homoeologous group.

对导入赖草优质耐盐基因的株系Line15进行了C-分带、荧光原位杂交、SSR相结合的鉴定，确认Line15是一个二体异附加系，附加的一对染色体与小麦的第二同源群长臂、第三同源群着丝粒和第七同源群短臂密切相关，并确定了Line15的外源染色体C-分带特征带型，为目后鉴定Line15附加系的真伪提供了简便快捷的途径；对抗旱附加系Line17进行了荧光原位杂交和SSR检测，得出Line17也是一个二体异附加系，外源染色体与小麦的第四同源群短臂密切相关。

On the basis of an analysis to both of them,it's obvious that the first is the foundation of the second,and it provides structural system and disquisitive thoughts for the second.

通过对两者分析，可以发现前者是后者的基础，它为后者的发展提供了结构框架和研究思路。

The phylogenetic trees reconstructed by MEGA based on the sequence data indicated that the 12 species referred here were divided into 3 groups: Dinodon rufozonatum and Sinonatrix annularis was the first group, Zaocys dhumnades and Ptyas korros the second group, and the genus Elaphe the third group which had a close relationship with the second one.

在此基础上用MEGA软件重建的系统发生树表明，研究的11种游蛇科蛇类可以分为3组：第一组为赤链蛇和水赤链游蛇，第二组为乌梢蛇和灰鼠蛇，第三组为锦蛇属的蛇，它们与第二组较近。

A first pair of additional yarns (20, 22) are intermeshed in a first intermeshing pattern repeat with the MD yarns outwardly of the endmost of the CMD yarns at one of the opposed ends and a second pair of additional yarns (24, 26) are intermeshed in a second intermeshing pattern repeat with the MD yarns outwardly of the endmost of the CMD yarns at the other of the opposed ends.

第一对附加纱线(20、22)在所述相对端的一端处的最外端CMD纱线外侧以第一交织图案循环与MD纱线交织；第二对附加纱线(24、26)在所述相对端的第二端处的所述最外端CMD纱线外侧以第二交织图案循环与MD纱线交织。

In addition, the Exactive has the same HCD scanning capability of the LTQ-Orbitrap, but is a faster system, providing 10,000 resolution at 10 scans per second, or 100,000 resolution at 1 scan per second.

除此之外，Exactive有和Orbi同样的HCD能力，但采集速度更快，可每秒获得10张10，000分辨率的谱图，或者每秒获得1张高达100，000分辨率的谱图。

The second year, it fruited 5 apples,4 ones were taken away, and only one could be kept."Haw-haw, I got 10% last year, and get 20% this year!Doubled!" the psychology of this apple tree balanced.But, it can also grow like this:Continue to grow up.For example, the second year, it fruits 100 apples and 90 ones are taken away ,it can keep 10 ones. But it doesn't matter, it can also continue to grow up and fruits 1000 apples in the third year

Although he went to the bench late in the second quarter grimacing and holding his shoulder, he returned in the second half to finish his nine-point, 3-of-11 performance.

尽管他在第二节后期一脸痛苦地坐回板凳，但在下半场他依旧回到场上，完成了11投3中得9分的表现。

Based on 3D steady and incompressible N-S equation and k-ε turbulent model, the aerodynamic performance of three different design options of 160 km/h container flat wagon was analyzed and compared using finite volume method. The three design options are as follows: the first design option has no headwall and the side surface of side beam is flat; the second and the third both have headwall and high side beam, and the side surface of side beam of the second is obtuse, while the third is cambered.

基于三维、不可压、定常N-S方程和k-ε双方程湍流模型，采用有限体积法对3种不同设计方案在运行时速为160 km/h的集装箱专用平车在有、无横风情况下的气动性能进行分析与比较，其中：方案一的平车无端墙，侧梁侧面平直；方案二和三的平车均加有端墙，且侧梁加高、侧面形状分别为钝形和弧形。
