查询词典 study

Methods (1) The device for study was determined by comparing the fluorescent images obtained by laser scanning confocal microscope and CCD fluorescent microscope respectively. The mercury-arc lamp of fluorescent microscope was studied to value its possibility to be used as the irradiation light source. Various image analyzing and processing methods were compared to determine which one was the best to be applied in this study.

(1)实验系统的建立：分别利用激光扫描共聚焦显微镜和CCD荧光显微镜采集ECV 304细胞的DCF荧光图像，并比较两者的成像质量，实验可操作性等技术指标；主要测量输出功率、功率稳定性以及光斑直径这三个指标，考察荧光显微镜的高压汞灯作为本研究中照射光源的可行性；比较并选择合适的荧光图像的分析与处理方法。

Results (1) CCD fluorescent microscope was superior to laser scanning confocal microscope in collecting the fluorescent image of DCF. CCD fluorescent microscope was chosen to be the system applied in this research with the consideration of operation, cost and et al. The mercury-arc lamp of fluorescent microscope was fit for the requirement of our study. The wavelength range of the light output was 460-490 nm and the power density was about 100mW/cm in the condition of our study. Organelle-cell fluorescence intensity ratio analysis was more suitable than other methods.

结果：(1)CCD荧光显微镜采集到的DCF荧光图像的质量优于共聚焦显微镜，同时综合考虑包括采图质量、光照射剂量的可控性、实验成本和操作简便性等诸多因素，最终确定了CCD荧光显微镜作为实验研究的工具；荧光军医进修学院硕士学位论文中文摘要显微镜的汞灯输出功率稳定，光斑均匀，经本实验所选取的光路系统后输出波长范围为460一490nm，功率密度约为1 00 mw/cm；细胞器一细胞荧光强度比值法对于荧光分布位置的确定优于其他方法。

Through "minor term" study glossary study glossary, should also utilize the target key points, the foundation advance principle, causes the student to grasp one batch of energies enormously reliably "the minor term", thus establishes own "the basic vocabulary".

学习词汇，也应运用突出重点，基础先行的原理，使学生牢固掌握一批能量极大的"小词"，从而建立自己的"基本词汇量"。

In this study, an effectual experimental method to study the minority carrier diffusion characteristics of Hg ~1-xCd xTe photodiodes was presented.

提出了一种对碲镉汞(Hg 1-xCdxTe)光伏器件的少子扩散特性进行研究的有效方法。

This study was carried out in collective-owned summer grassland in Ganchaitan, which is located at the south foot of eastern Lenglongling Mountain (a branch of north Qilian Mountain), with yak and Tibetan sheep miscellaneously grazed on it. The grassland type could be classified as alpine meadow, dominated by Potentilla froticosa shrub. This study, under grads grazing stress, focused on the community structure, composition, species diversity, above-ground biomass of PFS, by using pane net sampling based on spatial distribution in stead of temporal succession. Results showed that: Grazing stress negatively related to the distance between grazing area and resident area.

以祁连山北支冷龙岭东段南麓的甘柴滩夏季牧场集体长期混合放牧的高寒金露梅Potentilla froticosa灌丛草场为对象，利用空间分布代替时间演替的方法，采用方格网法取样分析调查，对不同放牧压力梯度下金露梅灌丛群落的结构、组成、物种多样性、地上生物量进行研究，结果表明：①放牧居住点由远到近，放牧压力梯度不断增加，金露梅株高、密度、覆盖度、地上生物量和丛间草地的地上生物量均有不同程度的降低，地上的总生物量降低幅度达84.77%。

Different from the current cultural research and criticism that restrict to nation and nationality, the study of Chinese American literature should be concerned with its miscellaneousness. The subject of the study is no longer stable and uniform, rather their "multi-position" as well as "multi-situation" in culture have gone beyond the limit of nation and nationality, which reflect the cultural identification problem within a global and imperialistic context.

与今天以民族和国家为基本范畴的文化研究和文化批评不同，华裔的文学和文化具有混杂性，主体不再是稳定的、统一的，他们文化的"多重立场"和"多重处境"超越了国家和民族的范畴，凸现了在全球化和帝国主义语境下的文化认同问题。
