At last, as the example of squeeze casting with large ratio of height to diameter, the temperature field and stress field of high-leg casting were simulated and analyzed.
最后，以高脚杯形挤压铸件作为大高径比挤压铸件的实例，对其挤压铸造过程中的温度场和应力场进行了模拟和分析。
The distinct characteristic of squeeze casting with larger ratio of height to diameter is (heterogenous) distribution of squeeze pressure.
大高径比挤压铸件成形时的一个显著特征是压力沿着轴向分布严重不均。
Ratio of height and diameter, crown and root, of root cutting seedling were strong with more fibrous root, and higher rate of fungus root infection than untreated normal field seedlings.
切根苗的高径比与冠根比均在壮苗的适宜范围内，须根数量多，菌根感染率高，均明显优于未切根的普通大田亩，这将有效地提高造林质量。
