    水處理設備平流池、濃縮池、二沉池的刮泥機承載梁屬于桿梁結構。文中採用了有限單元法對其進行研究，並且給出了有限單元法的基礎理論和分析過程。
  2. ( 1 ) effects of externally applied electric fields on photorefractive two - beam coupling are analyzed. theoretic dependence of the intensity gain factor on applied field e0 in sbn : 60 is presented. and the experimental results obtained in two sbn : 61 : cr crystal samples with different dopant concentration show clearly that for properly applied fields, a larger f can be achieved effectively than that obtained with no field applied

    由兩塊不同摻cr濃度的sbn 61 cr晶體得到的實驗結果同時表明，適當的外電場作用能夠有效提高晶體的二波耦合增益，並且，外電場的作用使晶體的響應速度大大提高，而晶體的最佳耦合角與外電場之間沒有明顯的依賴關系。
  3. For example, one of us ( umstadter ) has demonstrated electron beams of a few million electron - volts whose “ brightness ” ( in essence, the concentration of particles in the beam ) exceeds that of beams made by conventional accelerators, mainly because the charges bunched in one pulse of the beam have less time to blow it apart by its own electrostatic forces

    例如烏姆斯塔特（本文作者之一）便曾展示過，具有數百萬電子伏特的電子線束之亮度（基本上，即是線束內的粒子濃度）超過了傳統加速器產生的線束，因為脈沖內束在一起的電荷根本沒時間以自身的靜電把別人擠開。
  4. The stress fields in misaligned welded joints, " t " type of plate welded joint, flanged beam and perpendicular flanged beam are calculated respectively, and their stress concentration factors formulation are obtained

    採用這兩類單元計算了錯位板接頭、 t型板接頭、工字梁焊接鋼結構和工字梁十字接頭的應力場，得到了相應的理論應力集中系數公式。
  5. Experimental results on butane and butane - plant oil flames indicated that, measurement precision by the multi - wavelength method is strengthened by taking radiation information on multiple wavelength units into consideration, and moreover, the radiation calibration procedure is simplified, in that a halogen light source is used instead of in situ flame radiation. in section 2, fluctuation and averaging analyses are carried out on optical transmission signals by particles passed through laser beams to derive particle size and concentration in measuring area, furthermore, correlation calculations are conducted on two adjacent laser beam signals to obtain flowing velocity of particle

    對丁烷氣體火焰及丁烷-植物油混合燃料火焰的測量結果表明，多波長分析方法優于傳統的雙色法，表現在兩個方面：一、由於綜合考慮多個波長單元上的火焰輻射信息，多波長方法的測量精度比雙色法有較大的提高；二、在多波長分析方法中，採用標準鹵素燈進行相對輻射強度標定，簡化了雙色法中的火焰絕對輻射強度的標定。
  6. While loading rectangular - section overhanging beam with one - side fillet, usually there is stress concentration problem occurred at the fillet position of part

    摘要一側帶有圓角過渡的矩形截面懸臂梁受力時，圓角處存在應力集中現象。
