Bioassay results revealed: compared with alcohol control, extracts at parameter 1, 4, 7 stimulated the absolute germination rate and potential, radicle growth, plumular axis growth, fresh weight, dry weight at different levels; extracts at parameter 2, 3 stimulated the all germination index except radicle growth and axis growth; extracts at parameter 6 stimulated all but radicle growth and fresh weight; extract at parameter 8 stimulated only the germination potential.

生物检测结果显示，与酒精对照相比：萃取参数1、4和7等条件苦楝叶提取物对杉木种子绝对发芽率、绝对发芽势、胚根长、胚轴长、鲜重和干重等发芽指标均表现出不同程度的促进作用，萃取参数2和3等条件苦楝叶提取对除胚根和胚轴外的各发芽指标起促进作用，萃取参数5条件苦楝叶提取物对除鲜重和干重外的各发芽指标起促进作用，萃取参数6条件苦楝叶提取物对除胚根和鲜重外的各发芽指标起促进作用，而萃取参数8条件苦楝叶提取物仅对绝对发芽势起促进作用。

The resol phenol-formaldehyde adhesive could be prepared from liquefied wood (wood: phenol=1:2) in phenol at r(subscript F/P) 1.8, r(subscript NaOH/P) 0.7 and resinification temperature 80℃. The physical properties of the poplar three-layer plywood bonded with LWR were similar to those with normal PF resins and also satisfied the demands of I level. Free formaldehyde content of plywood (0.1 mg/L) was lower than the E0 level set by GB/T 9846-2004 Plywood.

结果表明，采用料液比为1：2的液化物，F1.8，r0.7，树脂化温度80℃条件下合成的杉木液化物树脂压制的杨木三层胶合板满足I类胶合板强度要求，各项物理力学性能与常规PF树脂压制的板材相当，板材的甲醛释放量为0.1mg/L，远低于GB/T 9846-2004《胶合板》中的E0级要求。

And Toona sinensis were steam-treated at temperature 70℃ and 90℃ for 4 h and 8 h. The radial gas permeability and tangential gas permeability of the steam-treated specimens were compared with those of non-steam-treated one.

处理条件为：杉木和马尾松木材的汽蒸温度分别为90、100℃，假水青冈和香椿木材的汽蒸温度分别为70、90℃，处理时间分别为4 h和8 h，并对汽蒸处理前后木材的弦向和径向气体渗透性分别进行了测定。

In this paper, 12 years old Chinese Fir clones were studied on the genetic variation of growth properties, basic density and tracheid morphological characteristics. The main results were as follows.

本文综合研究了12年生杉木无性系试验林的生长性状、基本密度和管胞形态的遗传变异规律。

4In the Zero-span tension, the average longitudinal tensile strength of tested Chinese Fir tracheid was 357.39Mpa.

零距拉伸中，被测杉木管胞抗拉强度平均值为357.39Mpa。

Most understory plants populations display aggre-gated spatial distributions.Daphniphyllum glaucescens,Eurya nitida,Schima superba,Ficus hirtaand Woodwardia japonica and so on have larger niche breadth.

The whole structure has been mortised together with the high quality wood of China Fir and has not been nailed without a single nail, without a single clinch bolt or any other iron pieces.

整个结构已mortised与高品质的木材杉木和尚未钉没有一个钉子，没有一个单一的克林奇螺栓或任何其他铁件。

Latiusculum in the gold field is 135, 111 and 147 times as much as that in the background area, respectively; and Cu and Pb contents in leaf ash of these three types of plants in the gold field are 12, 8, 11 and 11, 11, 14 times as much as that in the background area, respectively.

对从金矿区和背景区采集和试验种植的植物样品的研究表明，在杉木、马尾松和蕨的叶灰分中，矿区相对于背景区，前者的Au含量是后者的135倍、111倍和147倍；前者的Cu是后者的12倍、8倍和11倍；前者的Pb是后者的11倍、11倍和14倍。
