Compared with the 5. 8s complete sequence of the snail arion rufus, its1 and its2 regions were recognized and combined for analysis. from sequence observation, it showed that the zhejiang sample has more inserted sites and fragments while the sequences of other three are nearly all the same. the average g % + c % of the four individuals was 46. 8 % while the zhejiang sample ' s was 48. 3 % and the other three ' s were all about 46. 2 % ; ts / tv and genetic distance mainly lies between the zhejiang sample and the other three individuals, which were 0. 8 and 0. 07 respectively
用於比較的序列長約350bp ，觀測一級結構，加拿大、墨西哥灣扇貝和美國二代個體的its1和its2序列幾乎完全相同，而浙江個體則具有較多的插入位點與片段； 4個個體平均g + c含量46 . 8 % ，其中浙江個體為48 . 3 % ，其它3個個體均為46 . 2 %左右；轉換顛換比與遺傳距離主要存在於浙江個體與其它3個個體之間，分別為0 . 8和0 . 07左右；以櫛孔扇貝作外群構建的分子系統樹表明：浙江群體已產生了一定的分化。 -
The differences in orbital morphologies due to different potentials is slighting, however, given a certain potential, for clusters that have perigalactic distance smaller than 1 kpc, some orbits may exhibit a chaotic behavior. the correlation between the metallicity of samples and the orbital morphologies is unclearly ; ( 4 ) it is found that the semi - major axis, apogalactic distance and azimuth period of 29 sample clusters are changed with their metallicity similarly, but a obvious correlation is seen between orbital eccentricity and metallicity. there is a fraction of 24 % of the sample clusters with eccentricities lower than 0. 4
不同的引力勢模型對球狀星團軌道的具體形態影響不大，在給定的引力勢模型下，當某些星團的運動軌道穿越距銀心1kpc附近的區域時會出現「混沌」現象： （ 4 ） 29個樣本星團的軌道半長軸、遠銀心距和方位周期隨金屬度的變化規律基本相似，樣本星團的金屬度與其軌道形態之間的相關性並不明顯，然而軌道偏心率與金屬度有關，對于所選的暈族樣本星團而言，大約有24的樣本星團的軌道偏心率低於0 . 4 。 -
We find that the change of distance between lens and sample cell will result in the change of lower limit of measurement. analysis of mie theory indicate that, at the position of 7 ? angle relative to optical axis, normalization light scattering energy increases followed by the increase of particle size, but at the angle of 35 ?, the trend is opposite
並從理論上分析了亞微米級顆粒粒徑與歸一化散射光能量的關系，指出在與光軸成7夾角的位置，歸一化散射光能量隨著粒徑的減小而減小；在35角處，歸一化散射光能量隨著粒徑的減小而增大。 -
First we construct a covariance matrix from sample images, then compute the eigenvalues and corresponding eigenvectors of the covariance matrix, construct a feature matrix with the eigenvectors. then every images in database can be projected into the feature matrix and gain a projection vector, so does the input image. then we can judge the resemblance between input image with each image in database by computing the distance between their projection vectors
我們首先根據採集的樣本圖像構造一個協方差矩陣，然後求取該矩陣的特徵值，以這些矩陣特徵值對應的特徵向量構造出一個特徵空間，然後將輸入圖像向該特徵空間映射，將獲取的映射系數與樣本庫中圖像的映射系數進行距離計算，根據計算出的距離判定輸入圖像與樣本圖像間的匹配程度。 -

The interaction mechanism of atomic force between tip and sample was unveiled more clearly with the analysis of the change regularity of force - distance curve. the theoretical research about the light pressure of laser and the gravity exerting on the micro - cantilever was first conducted in this paper : setting up the interacting model and formula of the light pressure, investigating the effects of these factors on the interaction mechanism of atomic force and the performance of afm, conceiving a method to remove these effects and so on. all of these were the theoretical foundation of developing the new atomic force microscopy and the new type of horizontal afm system
本文在全面分析掃描探針顯微鏡（ spm ）技術，特別是afm技術的國內外發展歷史、現狀及存在的主要問題的基礎上，進一步揭示了afm的原子力作用機理，著重分析了力?距離曲線的變化規律；對作用在微懸臂上的光壓力和微懸臂本身的重力進行了系統的理論研究和計算分析，建立了激光束對afm微懸臂的光壓作用模型及計算公式，考察了這些因素對原子力作用機理及afm性能的影響；提出克服或消除這些影響的理論構想，為發展新的afm技術、研製新型afm系統提供了重要的理論依據。 -
At the same time, we consider the reconstructed ermrs of a test sample in two spaccs : the between - class eigenmotion subspace and the within - class eigenmotion subspace, which are used as the classifier rule, in contrast to the traditional methods such as euclidean distance or mahalanobis distance in one subspace. experimental results show that this method outperforms the eigenface method in the presence of facial expression variations
在特徵運動的基礎上，我們還提出了同類特徵運動空間和異類特徵運動空間兩個子空間的概念，並且分析測試樣本在這兩個子空間的重建誤差，以此作為分類標準，而不是簡單地考慮在一個子空間里歐氏距離或者馬氏距離。 -
