But recent survey reported that Panicum maximum, a perennial grass in the family of Poaceae and listed as one of the twenty most noxious invasive plants in Taiwan has replaced the role of M sinensis in those areas. As a result of recurrent burning, A. confuse forest has been gradually replaced by the grassland of P. maximum. In this study, I compared morphological, photosynthetic, growth and life history characters of field growing P.

早期的研究指出：在大肚山与铁砧山区的本地植物芒草为当地相思树林反覆火烧后的最优势种；但近年来同一地区的研究显示：大黍已取代芒草的角色，而且发现大黍在火烧后植群覆盖度显著的增加，但芒草却没有相同的现象；反覆火烧使得大肚山地区的相思树林逐渐转变成以大黍为主的草生地。

Compared with PF6P, the attachment of alkyl or alkoxyl groups on phenylene effectively inhibits the formation of fluorenone-based excimers and thus remarkably improves the thermal stability of the spectra.3. Morphology and phase behavior of the polymers substituted with alkyl and alkoxyl groups on phenylene were investigated by differential scanning calorimetry, X-ray diffraction and other techniques.

一方面，未取代的PF6P薄膜和烷氧基取代苯的PF60C6薄膜在空气中退火后都产生了芴酮结构，随退火温度的升高所生成的芴酮结构的含量逐渐增大；另一方面，新的长波发射随退火温度的升高其荧光寿命明显增加，因此确定PF6P空气退火薄膜的长波发射是来源于芴酮的激基缔合物。

In general under ideal perfect competitive environment, because of the replaceability the active output of a certain generating set will fall in vast scale while its bidding price is slightly raised, and the sensitivity index based on its own price will be a very small negative value; along with the increment of market power this index will gradually increase until sensitivity index becomes zero. This conclusion can be spread to the situation of multi-generating sets.

在理想的完全竞争环境中，由于可替代性，某台发电机组稍微提高投标价格一般会导致其有功输出的大量减少，基于自身价格的灵敏度指标为很小的负值，随着机组市场力的增加，该指标逐渐趋于增大，直至为零，此结论可推广至多台机组的情形。

Approximately 5% of subjects who had a perforation died within 14 days of the procedure. Risk of death was significantly increased by perforation after colonoscopy (OR, 9.0; 95% CI, 3.0 - 27.3) or after sigmoidoscopy (OR, 8.8; 95% CI, 1.6 - 48.5). The difference in risk between the two procedures has been narrowing because the risk of perforation from colonoscopy has decreased over the years, presumably from improvements in technology and in training.

约有5%发生肠穿孔的民众在筛检后14天内死亡，做完直肠镜或大肠镜后发生肠穿孔的民众死亡率明显增加（大肠镜：危险比，9.0；95%信赖区间，3.0 - 27.3；直肠镜：危险比，8.8；95%信赖区间，1.6 - 48.5），但这两种筛检方法的风险差异正在逐渐缩小中，可能是因为技术的改良与人员的加强训练，使得大肠镜的肠穿孔危险已逐年下降。

The results indicated that with the increasing of storage time, the leaves etiolated, contents of crude-fiber increased, while vitamin C, chlorogenic acid decreased, nitrate contents up to the maximum at the 3th day after storage , then decreased gradually. Stored at 2℃, the contents of chlorophyll, vitamin C, chlorogenic acid were higher, nitrate and crude-fiber contents were lower. The lower of membrane permeability and MDA content, the higher activity of SOD significantly delayed senescence process and prolonged storage life of Taraxacum mongolicum.

结果表明：采后蒲公英随着贮藏天数的增加，叶片逐渐黄化，粗纤维的含量升高，维生素C和绿原酸含量下降，硝酸盐含量先升高后降低；2℃下贮藏能够使采后蒲公英具有较高的叶绿素、维生素C、绿原酸，较低的硝酸盐和粗纤维含量，较低的细胞膜渗透率、MDA含量和较高的SOD活性，显著地延缓其衰老进程，延长贮藏寿命。

It had become evident that the simple, familiar, and unceremonious ways which had marked the Franciscan movement at its beginning were gradually disappearing, and that the heroic poverty practiced by Francis and his companions at the outset became less easy as the friars with amazing rapidity increased in number.

它已成为明显的是，简单，熟悉，和粗鲁的方式这标志著方济各运动在其开始逐渐消失，而且贫穷的英勇实行弗朗西斯和他的同伴在开始变得不那麼容易的修士具有惊人的速度增加在号码。

The silicone rubber based on PDM-MVS/PMMA blend had microphase-separated structure consisting of PMMA domains uniformly dispersed within a continuous PDM-MVS matrix.

结果表明，随着PDM-MVS中乙烯基质量分数的增加，共混物的黏度逐渐增大；由PDM-MVS/PMMA共混物制备硅橡胶的物理机械性能明显优于α，ω-羟基聚二甲基硅氧烷／PMMA共混物制备的硅橡胶；制得的硅橡胶具有微观相分离结构，PMMA分散相均匀地分布于PDM-MVS连续相中，两相的相容性良好。

The analysis results for community species component and plant diversity showed that exclusion did change the species component and increase plant diversity remarkably, while the indicateor life-form structure, palatability analysis indicated that community for old exclusion is becoming perennity and unpalatability, whereas community for comparative exclusion is under stable non-equilibrium condition, in the view of vegetation coverage, mean height, biomass, palatability of plant composition, community for old exclusion has lower than new, comparative exclusion which proves partly that long-term exclusion can not increase grazing values for semi-arid rangeland.

对3种封育措施群落组成和生物多样性的分析结果表明，封育改变了群落的组成成分并增加了生物多样性，同时对群落植物的生活型、饲用价值分析计算结果则显示，老封育的群落植物逐渐向多年生发展，放牧价值开始降低，而对照区则明显处于一种非平衡的稳定状态。从3种措施植被的盖度、高度、生物量和饲用价值来看，老封育区均低于新封育区和对照区，表明长期封育不利于促进并提高草场的放牧利用价值。

The numerical results for semiconductor heteroj unctions consisting of III-V group show that the contribution from 10 phonons with higher frequency can not be neglected in weak field limit, although the bulk LO phonons are more important to influence on the PCM. As increase of a magnetic field, the contribution from the two branches of 10 phonons tends to be comparable with that from the bulk LO phonons.

对Ⅲ—Ⅴ族GaAs/AlAs半导体异质结的计算结果显示：在弱场极限，尽管体纵光学声子对极化子回旋质量的影响更为重要，但高频支光学声子的贡献是不容忽略的；随着磁场的增加，两支界面声子的贡献逐渐变为与体纵光学声子的贡献相比拟。

Better denitrification efficiency could be obtained with adding amylo and the removal ratios of ammonia nitrogen were at least 93%. The removal ratio of TN increased gradually with the increasing of C/N ratio. When C/N ratio was 10, the best removal ratio of TN could reach 80.81%. But when C/N ratio added on 12, the ratio removal of TN was not increased only keeping about 75%.

投加淀粉调整C/N比，系统能取得良好的脱氮效果，氨氮的去除率均在93%以上，随着C/N比的增加，TN的去除率也逐渐的增大，当C/N为10时，TN最高去除率能达到80.81%，但当C/N增大到12时，TN的去除率不再增大，只是稳定在75%左右。
