  1. Weight accounted for the greatest proportion of age - adjusted bmd variation ( e. g., at femoral neck, r2 = 0. 17 in males ) among four variables : weight, height, bmi and a principal component formed from weight and height

    身高、體重、體重指數和從身高和體重的主成分分析產生的第一主成分是與骨密度有關的變量，在這四個變量中，體重是解釋骨密度變異（如：在男性股骨頸， r ~ 2 = 0 . 17 ）最高的變量。
  2. Our empirical findings reveal that wage earnings dominated family income distribution, personal wage unequally distributed mainly because of the variation of the wage rate, rather than the variation of working hours, and age was the most important determinant of the wage variation

    實證結果顯示：工資收入系決定家戶所得分配的首要因子；個人工資之不均則源於個人間工資率之變異，而與個人工時變異之關系甚微；最後，年齡的變異又是決定個人工資率不均最重要的因子。
  3. Some conclusions are drawn : the compressive strength and flexural strength of cubic specimens of steel fibre reinforced concrete increase with the dosage of steel fibre ; without change of dosage of steel fibre, the elastic modulus of steel fibre reinforced concrete increases with the concrete age ; steel fibre reinforced concrete is of obvious function in cracking resistance, but there is no obvious function in avoidance of cracking ; for both common concrete and steel fibre reinforced concrete, the variation of the internal temperature is different from that of the external temperature before the initial set of concrete, and the internal strain of both two kinds of concrete is great, and, in general, the variation of strain of common concrete is much greater than that of the steel fibre reinforced concrete ; after the initial set of concrete, the variation of the internal temperature of both two kinds of concrete is similar to that of the external temperature, and the variation of the internal strain is relatively small

    結果表明：鋼纖維混凝土立方體的杭壓強度、抗彎強度隨著鋼纖維摻量的增加而增大；在鋼纖維摻量不變的情況下，鋼纖維混凝土的抗壓彈性模量會隨著齡期的增加而提高；鋼纖維對混凝土的阻裂作用很明顯，而對混凝土起裂的限製作用不明顯；在混凝土初凝之前，無論是普通混凝土還是鋼纖維混凝土，內部溫度的變化規律與外界溫度的變化規律不同，並且此階段混凝土內部應變的變幅很大，普通混凝土應變的變幅要比鋼纖維混凝土應變的變幅大得多；在混凝土初凝之後，無論是普通混凝土還是鋼纖維混凝土，內部溫度的變化規律與外界溫度的變化規律相同，並且此階段混凝土內部應變的變幅很小。
  4. Adopting fd - 1 admixture, c50 concrete can be obtained, which has excellent adaptability for environment temperature ? 5 c ; self - shrinkage of concrete is inevitable, and its variation tendency based on w / c and hydration age, fd - 1 has wonderful inhibition for self - shrinkage, and meanwhile anti - friction property can be promoted

    在fd - 1組分對負溫混凝土的耐久性能研究中，認為影響自收縮的主要因素是水灰比和齡期； fd - 1外加劑對水泥自收縮有很好的抑制作用，能夠有效的提高水泥砂漿的耐磨性能。
