The results indicated that there existed significant differences in growth rate and wood quality among the provenances. A classical clinal variation pattern responding to the latitude of seed sources was found for DBH, height, individual volume and stem straightness, and water and heat resources of seed sources were the main climatic factors which caused the variation.

结果表明：马尾松生长、形质和木材基本密度皆存在显著的种源差异，种源胸径、树高和材积生长及树干通直度呈典型的纬向倾群变异模式，这种变异主要是由其产地水热资源条件差异引起的。

The results showed that: with the regression analysis of Betula platyphylla, Pinus koraiensis, Abies nephrolepis, Picea koyamai var koraiensis, and Betula costata, there was a significant negative correlation between neighborhood interference index and the growth (0.40~0.89) and the correlation extent depended on the neighborhood influence zone and slope. The neighborhood influence zone corresponding to maximal regression coefficient R~2 was the neighborhood influence radius. Based on the linear subsection regression between neighborhood interference index and influence zone of five species, the neighborhood interference index increased with the increasing zone and there was a previous increasing trend in a certain scope, while the increasing trend slackened beyond the zone. The neighborhood influence zone corresponding to transition point was the neighborhood influence radius. The neighborhood interference index positively correlated with the neighborhood influence zone and the range of R~2 was 0.40-0.64. With the analysis of tree cores of Juglans mandshurica, Fraxinus mandshurica at middle and lower slope in a plot which was fostered in 1995, the distance which the growth release farthest neighborhood and object stub was judged, thus the neighborhood interference radius was inferred. According to the studies, we found that the neighborhood interference radius was different among different trees, even if the neighborhood interference radius of the identical tree species also had the difference at different slopes.

结果表明：通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与生长量回归分析发现，邻体干扰指数与生长量呈显著负相关(0.40～0.89)，相关程度因邻体影响范围和坡位而异，R~2达到最大值所对应的影响范围即为邻体影响半径；通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与影响范围的线性分段拟合，邻体干扰指数随影响范围的增加而增加，其在一定的范围内上升较快，而超出该范围后上升的幅度变慢，变化的转折点所对应的影n向范围可以判定为邻体影响半径，线性回归显著(0.40～0.64)；通过对1995a抚育的胡桃楸、水曲柳样树进行研究，分析邻体树种的中坡位和下坡位的生长锥芯，判断产生生长释放的最远邻木与基株树桩所对应的距离，推断邻体影响半径；根据研究发现，邻体影响半径因树种不同有一定的差异，即使同一树种的邻体影响半径在不同坡位也有一定的差异。

The induced amino acid sequence identity with other cucurbitaceous ribosome-inactivating proteins was up to 68.90%, with TCS was 71.25%, with Gelonin was 71.25%, with Saporin was 66.45%. The amino acid sequences of 90 to 220 were conservative.

BC-MAP30和YT-MAP30基因的推导氨基酸序列与其他葫芦科植物的Ⅰ型核糖体失活蛋白以及天花粉毒蛋白、多花白树毒蛋白、肥皂草毒素蛋白的氨基酸序列同源性分别为68.90％、82.75％、71.25％和66.45％，且其第90～220位氨基酸序列较为保守。

The content of oil in kernel and that of phorbol ester in defatted kernel of Jatropha curcas from different origins were studied in this paper.

选用国内4种不同产地的麻疯树种仁，对其含油量以及脱油后的佛波酯含量进行了研究。

Concerned with the extent of transient expression of explatns, the results show that the effectiveness of transient expression is rather high(60%) after the cotyledons of Jatropha curcas L.

为了构建麻疯树的遗传转化体系，首先应建立其高频再生和高效转化系统，而瞬时表达测试是优化转化系统条件的快速有效的方法。

On the basis of census of all individuals of the populations at different plots, the structure and dynamics of the populations were described. The result showed that P. tabulaeformisf.shekannesis were growing populations, and the distributions of the structure were reverse J. The density decreased with the increasing of Size-class structure. The populations developed the characteristic of increasing in the early stage and stabilizing in the late. The survive curve of Pinus tabulaeformisf.shekannesis were between DeeveyⅡand DeeveyⅢ. The analysis of time sequence showed that most of the inividuals would be adult after 20 years.

结果表明：柴松种群结构呈反J分布型，种群处于增长阶段；种群的密度随径级的增加而降低，种群密度与径级呈现出明显的负相关；四个函数估计值说明柴松种群具有前期增长、后期稳定的特点，其存活曲线介于DeeveyⅡ型和DeeveyⅢ型之间；随时间推移，种群中树和大树数量逐渐增多，种群在20年后开始大量进入成熟阶段。

OpenFlight , as a recognition standard in virtual reality region , has a biggest merit . It is dendriform administrative levels . It provides huge advantage in projects management.

作为虚拟现实业界公认的模型OpenFlight标准，层次化的树状结构是其最大优点，这也为项目管理提供了极大的便利。

The core thought of dendriform topology discovery algorithm is the brother-node guess algorithm, which can obtain the address space scanning by other means.

树状拓扑结构发现算法的核心思想是最小增量发现算法兄弟节点猜测算法，其优点在于采用了非地址空间扫描的手段却达到了地址空间扫描的效果。

In general, the more dendrites and synapses the brain has, the greater its processing power.

在一般的，更多的树突和突触脑，其更大的处理能力。

Diploblastic cnidarians as the outgroups, the phylogenetic trees of bryozoans and lophotrochozoans were reconstructed by the 28S rDNA analyses of theirs and other related bilaterians obtained through GenBank with different methods, respectively. Meanwhile, the primary and predicted secondary structures of their partial divergent 28S rDNA domains were compared and analysed.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
