    是痔瘡，不要擔心，這是個發病率很高的病，有十人九痔的說法，也就是說幾乎每個人都有不同程度的痔瘡，有的重，有的連自己也覺察不到，我推薦你使用痔根斷，是口服藥，德國進口的，一盒四十元左右，到大點的藥店一般都有，每盒80粒，天天吃三次，每次三顆，吃完三天就有效果，但是這個藥是要求可以堅持吃完一盒的，然後平時飲食注重不要辛辣刺激，不要讓自己上火，多吃水果多喝水，保持大便通暢，就可以了，假如不好意思就不要看醫生了，因為醫生一般會建議你做手術，不太好，手術也不能保證完全治好，假如你是未生育過的女性，那就更不要做手術了，因為以後生小孩時，用力過大還是會引發痔瘡復發的，相信我，另外你可以配合一個外用藥，馬應龍痔瘡膏，塗在外面，比較舒適，這個比較便宜，幾塊錢，快去買藥吧，不要耽誤太長時間，不然到了大便帶血的程度就痛苦了。
  2. The asteroids are the most important small bodies in the solarsystem, and they mainly lies in the two locations - a main belt between the mars ' s orbit and the jupiter ' s and the near - earth space. the most feature of the orbits of near - earth asteroids ( neas ) is that the semi - major axes of the orbits are nearly equal to that of the earth or the perihelia distances are approximate to or even less than the mean distance between the sun and the earth, thus they could move into inside of the earth ' s orbit, so that they might close approach or even colliside with the earth ( or other planets, such as the venus, the mars, etc. ). the characteristic brings about some difficulties in the numerical research during their orbital evolution, which leads to the failure of the normalization technique in the general removal impact singularities of celestial mechanics methods and the symplectic algorithm which is successfully applied to the investigation in quality. by comparing the computation effects of several common numerical methods ( including symplectic algorithm ), and considering the nature of the movement of the small bodies, the corresponding treatments are provided here to improve the reliability of the computation

    小行星是太陽系最重要的一類小天體，主要分佈在兩個區域；火星和木星軌道之間的一條主帶和近地空間.近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深入到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞.這一特徵給其軌道演化數值研究帶來一些困難，包括天體力學方法中一般消除碰撞奇點的正規化處理以及對定性研究十分成功的辛演算法都將在不同程度上失效.通過對幾種常用數值方法（包括辛演算法）計算效果的比較，根據小天體運動自身的特性，給出了相應處理措施，從而可提高計算結果的可靠性
  3. The radiation pattern of the antenna is more rotationally symmetric, and a more reduction on the sidelobe levels of the antenna is achieved as compared to the antenna with the corrugated soft surface. in conclusion, in the present thesis both theoretical and experimental research works have been carried out intensively on patch antennas based on photonic - bandgap structures. it is shown that our photonic bandgap structures can greatly improve the performance of the patch antennas

    該平面圓環結構軟表面天線是在空氣介質的皺褶圓環結構軟表面天線的基礎上改進得到，為了便於比較，我們首先研究了空氣介質的皺褶圓環結構軟表面天線，用fdtd方法並結合pml吸收邊界條件對該天線的性能進行了研究，結果表明天線的帶寬增加，天線的軸對稱性得到了很大改善， e面和h面方向圖的波束幾乎重合，天線的旁瓣和背瓣受到很大的抑制。
  4. Based on the basic principle of wavelet analysis, multi - resolution analysis of signal in atomic clock is made. the coefficients of wavelet transform for synthesis atomic time, which are weighed and averaged at different wavelet scales, are obtained. then according to reconstruction theorem, multi - resolution synthesis time scale can be reconstructed. since the signal of atomic clock has been analysed by multi - resolution, we can use wavelet variance at different scales to weight and average the coefficients. thus either the difference in stability of different clock or the varying characteristic of the same clock at the different scale are all considered. finaly, this method is checked by the measured data from national timing serve center of shaanxi astronomy observatory. it confirmed that this technique, which is simple and practicable, is a new method of multi - resolution. from this method, the common characteristic of different clocks can be extracted. the stability of multi - resolution synthesis atomic time scale is obviously superior to that of other methods

    本文根據小波分析的基本原理，對原子鐘信號進行多解析度分解，將分解后的小波變換系數進行加權平均，得到不同小波尺度綜合原子時的加權平均小波變換系數，然後由小波變換的重構條件，反演綜合時間尺度.由於對原子鐘信號進行了小波分解，利用不同尺度的小波變換系數的小波方差進行加權平均，這樣既考慮不同原子鐘在穩定性方面的差異，又顧及同一臺原子鐘在不同小波尺度的變化特性.最後根據陜西天文臺國家授時中心的實測數據對這種方法進行了檢驗.表明這是一種全新的多解析度綜合方法，這種方法比較簡單而切實可行，它能提取各個原子鐘的共同特性，多解析度綜合時間尺度的平穩性明顯優于其他方法
  5. The recombinant pcr technic was used to introduce a linking peptide klgggg to the site between scfv single chain form of the monoclonal antibody sz - 51 specific for the glycoprotein gmp140 on activated platelet membrane and uk32 low molecular weight form of pro - urokinase, to make the scfv - linker - uk32 chimeric gene. this gene was cloned into the transfer vector pbacpak9, and cotransfected with bacpak6 bsu36i digest into sf 9 cells. the fusion protein was secreted into the medium. in the fifth day after the cotransfection, the supernatant of the medium showed 107 iu ml fibrinolytic activity, higher than 25 iu ml fibrinolytic activity of scfv - uk32. elisa showed that the supernatant had the binding activity to activated platelet. wastern blotting also indicated that the supernatant could bind to the monoclonal antibody of urokinase b chain

    為了提高重組導向溶栓分子scfv - uk32的溶纖活性，通過重組pcr方法在編碼scfv與uk32的堿基之間引入編碼klgggg連接肽的堿基序列，並克隆到轉移載體pbacpak9上，通過與線性病毒dna bacpak6 bsu36i digest共轉染到昆蟲細胞sf 9內，進行表達。表達產物分泌到上清中，共轉染后第5d天用纖維平板法測得sf 9細胞上清溶纖活性達到107 iu ml ，比未引入連接肽的scfv - uk32的表達活性25 iu ml高。
