It's necessary to have a simple and systematic digital model in thinning decision-making. In the paper, the tree location map of 150 m x 30 m Luanta-fir in Hui-Sun Forest Experimental Station were digitized in GIS and thinning simulation by random, Telathaki-Wadali-Chi, DBH class and crown competition index method.

本研究系利用GIS 配合林木位置图，以惠荪林场之150m x 30m 香杉采穗园为研究材料，以生产大径材为目的的考量下，针对疏伐木之选择，利用随机法、寺崎渡氏法、胸径级法、树冠指数法等四种方法加以模拟、评估、探讨。

The research of the utility and safety of the hammer was performed. The affecting factors of pile-soil system to the results of dynamic load testing were also analyzed. The results show that there is no tensile force in hammer during impact and it is feasible to utilize the hammer in drilling piles dynamic testing. Drop height, stiffness of cushion, pile length and diameter, and the soil qualities etc. affect the dynamic load testing results considerably.

研究结果表明：锤体冲击过程中基本不受拉力，符合试验要求；特大型组合式基桩高应变动力试桩重锤应用于灌注桩承载力检测是可行的；锤重、落距、桩径、桩长、土阻力分布、桩侧及桩端土弹限、锤垫刚度和力脉冲宽度等因素对检测承载力均有较大影响。

More unusual is a multi-function display , in the center of the dash, that not only gives a detailed log of the driving behavior - speed, g-force, fuel economy etc - but also gives details of the car's mechanical information (turbo boost, water and engine oil pressure, transmission oil, front/rear drive distribution etc) plus steering angles, braking and acceleration pressure, and also optimal gearshift mapping for best fuel economy.

更不寻常的是一个多功能显示器，在该中心的赛跑，不仅给出了详细的日志的驾驶行为-速度， g力，燃油经济性等-而且还详细介绍了汽车的机械信息（涡轮增加，水和机油压力，变速器油，前/后座径分布等），另加督导的角度，刹车和加速的压力，也优化变速映射为最佳的燃油经济性。

Path analysis of nine traits, which were highly correlated with tree volume, showed that the direct contribution of DBH and height on the variations of tree volume took up about 63% of the total variations. On the other hand, those traits, such as tree crown and wall/lumina, affected the volume strongly by indirect way of the genetic correlation with DBH and height.

通过对与材积性状紧密相关的胸径等9个性状的通径分析发现，胸径和树高两个性状对单木材积的直接作用占材积总变异的63％，其余性状的直接控制作用很小；冠幅、壁腔比等性状通过胸径对单木材积具有很大的间接遗传控制作用，这种控制是通过与胸径、树高的遗传相关实现的。
