计划性语言文化认同指某一语言文化的成员基于对另一语言的隐形优势的理解而放弃母语，并在另一语言文化的基础上建立一种新的语言文化认同。

After many year endeavors, the development has designed the high quality at low price "the low negative pressure aspirator", the product performance may the overseas similar products compare, the price is lower than the similar foreign product by far.

经多年的努力，开发设计了质优价廉的"低负压吸引器"，产品性能可以国外同类产品相比，价格是远远低于同类国外产品。

If your pixel scale is much larger than the values quoted above, then the quality of the astrometry will suffer. If your pixel scale is too low for your local setup, then the signal-to-noise of the images may be low as each image is spread over a large number of pixels.

如果你的像素分辨率比上面要求大很多的话，那么可能导致天文测量的测量品质下降，但如果你的像素分辨率比上面要求的小很多，则会导致图片的信噪比下降，因为每个目标占据了过多的像素。

Opening with减仓social security fund is more likely that an industry at a low ebb with the high point, and we can not say that the city market at low or high point.

In the catalyst after leaching, other than nanoscaled Ni crystallites, boundary area is observed from HREM. These areas are low contrast and high brightness. The atomic density of these areas should be low, therefore, it is suggested that they are rich in voids and phosphorus atoms.

高分辨电子显微观察显示，合金脱铝形成镍纳米晶的同时，还形成了纳米尺寸的低密度、高亮度的界面区域，该区域与其它文献中提到的孔洞尺寸相当，但认为它应该是富含铝及大量缺陷的结构疏松区。

Under soil water stress conditions, the photosynthesis rate, water useefficiency and light compensation point of Atriplex canescens obviouslyreduced, and its dark respiration rate weakened. In the treatments in July, theaccumulative and average value of daily Pn from high to low is: light soil water stress＞no soil water stress＞medium soil water stress＞heavy soil water stress, the valueare 7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1) and 1.761μmolm~(-2)s~(-1), respectively. In the treatments in August, the accumulative and average value ofdaily Pn from high to low is: light soil water stress＞medium soil water stress＞heavy soil water stress＞no soil water stress, the value are 7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1) and 1.705μmolm~(-2)s~(-1), respectively.

在土壤水分胁迫下四翅滨藜的净光合速率、水分利用效率、和光补偿点显著降低，暗呼吸速率减弱。7月份各处理Pn全天的累计值和平均值的大小顺序为：轻度土壤水分胁迫＞无土壤水分胁迫＞中度土壤水分胁迫＞重度土壤水分胁迫，它们的值分别为：7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1)和1.761μmolm~(-2)s~(-1)。8月份各处理的Pn全天累计值和平均值的大小顺序为：轻度土壤水分胁迫＞中度土壤水分胁迫＞重度土壤水分胁迫＞无土壤水分胁迫，它们的值分别为：7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1)和1.705μmolm~(-2)s~(-1)。9月份四翅滨藜的Pn变化趋势于8月份的变化曲线基本相似，唯一不同的变化就是各个处理的Pn比8月份的要高，这可能于9月份气温降低，湿度增大有关。

For the first time, the applied function of Copper azole preservatives for bamboo preservation has been studied; the advantage and shortage of CuAz on bamboo preservation has been analyzed; the mechanism and approach for formulation optimization of CuAz have been proposed. Moso bamboo , which is abundant in china, was used as experimental materials in this thesis. These investigations laid the foundation for the exploitation of bamboo preservatives with independent intelligent property right, low toxicity and high performance, high quality and low overhead.

本论文以我国资源丰富的毛竹为试验材料，首次对铜唑类防腐剂（Copper Azole，简称CuAz）在竹材上的应用性能进行研究，分析了铜唑防腐剂应用于竹材防腐的优势和不足，总结了竹材的腐朽机理、药剂的防护机理和固着机理，提出了铜唑类防腐剂配方优化的机理和途径，为竹材防腐剂的研发、优化和改造提供科学依据。
