  1. During its lifetime, the xd recorded a total of 664 triggers. the research team identified and recorded lightcurves of near one hundred solar flare events data taken during half of the orbit when the shenzhou - ii orbiter faces the sun and 30 candidates of gamma ray bursts. many of these observations were verified by similar results taken by other orbiting satellites

    探測器在運作期間，共錄得664次撞擊，研究小組由此識別並記錄了近百次太陽耀斑的變光曲線當神舟二號在軌道上面向太陽時和約30次伽瑪射線爆發，大部分觀測結果跟其他人造衛星所測得的類似。
  2. No trace of any newly expressed protein band was noticed in supernant as well as in the cells by sds - page, except the verification of the substitution of beta - galactosidase gene ( the lose of galactosidase protein band ), which is a selective marker of the wild - type virus. elisa test results suggested the expression of egf in cells, but not in culture supernant. the quantitative calculation suggested the expressed egf was about 6 - 7 u g ( as egf standard ) per flask ( 2 > < 106 cells ) in the cellular extract

    將重組病毒rbmbacph - egf以10moi感染bmn細胞， 72小時后收集培養細胞和上清；培養上清和經超聲波處理的細胞樣品elisa檢測發現胞內樣品中存在能與egf抗體免疫反應的產物，粗略估計表達量約6 7 g 2 10 ~ 6個細胞（相當于egf標準品） ；重組病毒rbmbacph - egf穿刺接種5齡家蠶幼蟲，每隔24h收集蠶血淋巴，經elisa檢測發現第4天表達量最高，根據egf標準曲線計算蠶血淋巴的表達量約32 g ml ； elisa定性實驗還發現正常蠶血也存在與egf抗體間交叉反應的物質。
  3. The apparent activation volume calculated by the model is about 2500a3, which was ten times larger than that of usual amorphous alloy and was at the same range of the amorphous polymer. the model shows the main deformation mechanism of nanocrystalline ag is grain boundary sliding, which in some extent declares the similar forms of equation with amorphous alloys. with the ananlysis to the hrem of nanocrystalline ag, the discrepancy of the apparent activation volume between the nanocrystalline ag and amorphous alloys is interpreted by the loss of atoms participating in grain boundary sliding without enough reconstruction by the movement of atoms under the low temperature

    運用晶界滑移的熱激活理論對壓縮實驗結果進行了數值擬合，擬合曲線與實驗數據符合很好，得到了晶界滑移的表觀激活體積（熱激活基本單位體積與局域瞬態應變的乘積） ，約為2500a ~ 3 ，先當于幾十個原子體積大小的瞬態變化，約為非晶合金的10倍以上，與非晶高聚物的表觀激活體積相當。
  4. Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence, observation of thin sections, and analysis of sr and mn. the mn / sr value of all samples presented in this paper are less than 2, and the cathodoluminescence is dull, however, the samples from the cambrian underwent diagenetic alteration to a certain degree, and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete. the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world, supporting the notion of global consistency of strontium isotope composition of marine carbonates

    根據鋸同位素地層學的基本原理，利用已有的鋸同位素演化曲線，筆者確定重慶秀山寒武系剖面寒武系底界、下一中寒武統界線和中一上寒武統界線都應適當下移；另外嘗試確定了重慶秀山寒武紀剖面一些關鍵點的年齡，累積厚度1380m處的年齡為503 ? 509ma ，累積厚度1900m處的年齡約為500ma ，這對秀山寒武系剖面下、中寒武統和中、上寒武統界線的確定具有參考價值。
  5. Secondly, the problem of the curve - surface mutual transforming and smooth - finishing have been analyzed farther. for the surface intersecting problem : owing to the introduction of the boundary points, as long as the intersecting points on a certain line, the full intersecting line can be gained. the intersecting line either intersects at the boundary of the triangle surface or forms the loop ; during the course of tracking, the selecting of the pace is restricted by the curvature, the number of the gained intersecting points are not in proportion as the chord - length ; the intersecting points not only record the coordinate and store the parameter

    對兩曲面求交問題，當曲面細化足夠小時，曲面求交可近似看成曲面與平面相交問題，引進了邊界點的概念，因此只要知道交線上的任意點，就可以將跨越許多曲面片的整條交線計算出來，所求出的交線或者跨越曲面的邊界，或者形成交線環；從初始點出發跟蹤求解整條交線的過程中，步長的選擇採用了通過曲面片曲率來約束的方法，用該方法求出的交點在不同曲面片上的分佈數目不與弦長成正比；該求交方法包含了各曲面片的邊界線與交線的交點的求解，可獲得邊界交點的坐標值及其參數值。
  6. But if the electron velocities are high enough ? at least six million meters per second, or about 2 percent of the speed of light ? the drag force actually decreases the faster the electrons go [ see illustration on page 69 ]

    但如果電子的速度夠高（至少每秒600萬公尺，約相當于光速的2 % ） ，則電子行進越快，阻力反而越小（見91頁曲線圖） 。
