  1. Considering the diffuseness of the n - n scattering in the forward direction results in an increased reaction cross section. and also the angular distributions calculated in the glauber theory including these two corrections are in good agreement with the experiment data. in the investigation of the halo nucleus reaction with a loosely bound structure, one has to consider the strong spatial correlations among its constituents

    考慮了低動量轉移的核子?核子兩體散射在朝前方向上的彌散，使計算得到的反應截面增大，而且我們從彈性角分佈的分析中得到考慮了有限力程修正的效應無論是在峰的位置還是角分佈的絕對值都能更好地符合實驗。
  2. Finally theoretical results and the experimental data have been compared and analyzed. the theoretical results are in good agreement with the experimental data. after evaluated, the results have been adopted in the nuclear data library of china

    理論計算的總截面、彈性截面、去彈截面和彈性散射角分佈等結果和實驗數據符合很好，同時該兩組光學勢參數以及計算結果被中國核數據庫收錄。
  3. These experimental results show that < q12 > is independent of the dimuon mass and logitudinal momentum, and imply the scattering of the incident quark within the target nucleus. by means of the glauber model, the difference of the mean transverse momentum squared < qt2 > is studied for the dependence of the incident proton energy and nucleus. the theoretical results are in good agreement with the fnal e772 experimental data

    本文利用多重散射的glauber模型，討論了入射夸克在原子核中傳播的多重散射效應，給出了兩個不同的核drell - yan過程產生的末態輕子對橫動量平方平均值的差值對入射粒子能量核靶核的依賴性關系，計算結果與e772組的實驗數據符合甚好。
  4. The object of iasr imaging is the moving target in space. the traditional rda algorithm is based on the model of micro - motion scatters, but it is not fit for the real target at all. we must adopt some methods to correct the error, which is caused by the model mistermination, and the discussion is mentioned in the paper firstly

    對于isar成像，主要是針對空中運動目標的成像，傳統的簡單的rda演算法是基於散射點的微動模型，但是實際的目標並非完全符合這個要求，所以必須採用一定的措施校正因為模型失配引起成像誤差，本文首先對此進行了討論。
  5. Using lewis - riesenfeld theory, we obtain exact solutions of the time - dependent system, then we recover both n - pulse method based on time - evolution operator of the system and stirap method in terms of instantaneous eigenstates with the help of time - dependent gauge transformation

    利用含時規范變換理論得到系統的精確解，我們用時間演化算符同時得到文獻中分別採用-位相法和stirap （受激拉曼散射）方法得到的結果，因而更具有普遍性。
  6. The calculated double differential cross section of the new model is compared with experimental data and previous scdw calculations with single particle model. the calculated cross sections are larger than those given by previous calculations at backword and forward angles and smaller than those given by previous calculations near the quasi - elastic scattering ( qes ) angle. the agreement with experimental data is much improved

    新模型的雙微分截面計算結果與實驗值以及以前採用單粒子殼層模型時的計算結果進行了比較，表明cdfm模型的引入對scdw模型的計算結果有較大的改進，使其在大角度和極小角度區域有所增大，在準彈性散射角附近有所減小，從而能更好地與實驗值相符合。
  7. Silylate - terminated polyurethanes with built - in hydrophilic sites were synthesized. when the polymer is dispersed in water, the silane alkoxy end - groups of the polymer undergo hydrolysis, followed by condensation to form a stable cross - linked aqueous dispersion. tem studies indicated that with more incorporation of hydrophilic sites, the particle size of the dispersion decreased. it was also found that the film property depended on the particle size when the crosslinking density in particels was much higher. the average molecular weight of the elastically effective network chain mc measured by swelling experiments shows fairly good agreement with the theoretical value of mc. it was also found that the cross - linking density of the casting film may increase during the film formation and drying process

    將硅氧烷封端的含親水基團的線性聚氨酯預聚體分散於水中，獲得穩定的聚氨酯分散體.由於硅氧基團水解、縮合，在分散體粒子內產生擴鏈交聯反應，生成了交聯水基聚氨酯分散體.透射電子顯微鏡研究表明分散體粒徑小、分佈寬.掃描電子顯微鏡研究了成膜結構及成膜性能與粒徑的關系.溶脹實驗計算獲得的兩交聯點之間的平均分子量與理論平均分子量相符.研究還發現此分散體膜在乾燥過程中可進一步交聯.膜的水溶脹及機械性能表明，此分散體具有極大的工業應用價值
