It was shown that these two strains both can utilize benzoate as sole carbon source and the maximum tolerance of benzoate are 1.7% and 1.600, respectively; These two strains both can grow on benzene, toluene, xylene, phenol, benzyl alcohol of as sole carbon source. Pfluorescens PFO1 can degrade dianiline, 3,5-dinitrosalicylic acid, p- dimethylaminobenzaldehyde while P. aeruginosa ATCC27853 can utilize 3,5-dinitrosalicylic acid, p- dimethylarninobenzaldehyde.

结果表明，两种菌都能在以苯甲酸钠为唯一碳源的基础培养基上生长，并且，对苯甲酸钠的耐受性分别达到1.7％和1.6％；两种菌都能以适当浓度的苯，甲苯，二甲苯，苯酚，苯甲醇为唯一碳源生长；荧光假单胞菌能以二苯胺，对二甲氨基苯甲醛，3，5-二硝基水扬酸为唯一氮源生长；铜绿假单胞菌能以3，5-二硝基水扬酸，对二甲氨基苯甲醛为唯一氮源生长。

When the TN:TP ratio was 25:1,V.spiralis had the best growth, with a biomass increment being 54% and 31% higher than that when the TN: TP ratio was 12.5:1 and 50:1, respectively, while the growth of periphyton, especially of epiphytic algae, was the worst, giving the least adverse effects on V. spiralis, indicating that a 25:1 of TN:TP ratio in eutrophic water was optimal for the growth of V. spiralis. However, such an optimal TN: TP ratio only worked when the nutrients concentration in eutrophic water was below the limited level, otherwise, it could be failed to be applicable.

结果表明：当TN/TP为25：1时，苦草的生长状态最好，苦草生物量的增长率最大，分别高于TN/TP为12.5：1和50：1时的54%和31%；当TN/TP为25：1时，附着生物尤其是附着藻类的生长状态最差，对苦草生长的不利影响最小；可见，富营养水体中适宜于苦草生长的TN/TP为25：1；TN/TP为25：1这一比例的应用具有相对性，当水体营养浓度低于限制水平时，该比例适用，如果水体中营养盐浓度超过限制水平时，该比例则不适用。

This attributes to the abundance remnant nutrients remaining in the stump. However, in later growing stage the difference between the two regeneration patterns gradually shrinks, in tree height the seeding individuals even exceed the sprouting ones. This reflects that the sprout forest exist premature senility phenomenon.

但是到了生长后期，两种更新方式形成的个体间生长量差异逐渐的缩小，在树高生长上实生个体的生长甚至超过了萌生个体的生长，这反应出了萌枝更新形成的萌芽林存在林木早衰的现象。

The tree diameter at breast height and crown length can be used to predict the size and location of mean knot diameter in a whorl.A linear mixed model expressed as function of tree and knot variables such as HK、RKD、KD and DBH was used to predict sound knot length,and a log-linear mixed model using RKD and DBH as variables was used to describe loose knot length.4.A knot has four development phases:from the birth of a branch to its growth cessation,from growth cessation to death,form death to occlusion and form birth to occlusion.The numbers of annual rings in four periods,as well as the stem width of respective zones were used as dependent variables predicted by models expressed as function of tree variables and knot attributes.5.Using the data of diameter out side bark of 15 relative heights along the step,the best taper equation for Larix olgensis was established.

Dead branches or knots in different sizes of tree was studied and different branch development phases of growth,suppression,death and self-pruning was analyzed to evaluate the effect that knot size and distribution impact on timber quality.Branch and knot dynamic models were developed using stand and tree variables.Based on multipleunit stepwise regression method, the individual tree growth model was established using forest and crown factors as the variable. The best taper equation model of Larix olgensis was bucking data of 130 sample trees selected in the studied area.

Besides playing an apparently key role in wall expansion, expansins have been implicated in an increasing number of processes including cell enlargement, seed germination, root hair formation, root growth, leaf primordium initiation,leaf growth, softening of fruits, fruit abscission and growth of the pollen tube of grasses through the stigma and the style.

目前认为扩张蛋白几乎参与了植物的整个发育过程：除具有增大细胞的功能外，扩张蛋白在细胞生长、种子萌发、根毛形成、根系生长、叶原基形成、叶子生长发育、果实成熟、器官脱离，以及花粉管生长方面起着重要的作用。

In the article a optical system was developed by the newest RC microscope with the schlieren method, which made the figure of appearance excellent colour and lustre and fine third dimension. The special cylindrical and cubic crystal growth cell was designed and the temperature-control system was developed to cooperate with the cell. Radial thermal gradient was formed in the cylindrical cell while transverse thermal gradient in the cubic cell, which was prepared for finding new effects.

Diamonds began growth when "Jiangnan continent" combined to Yangtze craton, the growth and residence average temperature T〓 was about 1200℃; Diamonds were mutil-stages growth and interruption caused by temperature and pressure varied during Yangtze craton activities; Diamonds were etched when the magma did not erupt on the surface and form failed magma in mantle; during the later growth term T〓＜1050℃, the type ⅠaA diamonds formed unclear and growth; Before the host magma erupted T〓＜0.5Ma, T〓A＜850℃, the type Ⅰb diamond formed unclear and growth; Few diamonds were brittle deformation during growth term, some were plastic deformation after growth; when the host magma erupted on the surface and weathered to alluvial deposit, diamonds surfaces formed green spots caused by irradiation, then most of green spots became to brown spots during a mid-temperature metamorphism; modern river reform it to alluvial deposit in the minute valley again.

在扬子地台&江南古陆&克拉通化时，金刚石开始生长，其生长与保存的平均温度T〓在1200℃左右；期间由于地台的活动，生长的温度压力条件发生了多次变化，使金刚石出现多次生长、停顿；夭折的母岩上侵活动使金刚石受到熔蚀作用；在金刚石形成的晚期，T〓值下降到1050℃以下，出现了另一次金刚石的生长期，在临近金刚石母岩上侵时T〓＜0.5Ma，温度进一步降到850℃以下，使Ⅰb型金刚石得以保存；在金刚石形成期间还有过碎性变形发生；金刚石形成后部分样品经过了塑性变形；金刚石在上侵过程中，遭受了强烈的熔蚀；在母岩露出地表，形成沉积砂矿时，受到了放射性物质的辐照，先形成表层的绿色斑点、壳层，后经过中低温的热变质作用，大部分绿色转化为褐色；现代河流作用对沉积砂矿进一步改造，形成现在的细谷型砂矿。

The rusults indicated that the temperature in forest was lower and the growth of ginseng was slower than out of forest, the yields were also lower; with the increase of ginseng age, the rate of net photosynthesis became higher; when the canopy density of forest reached to about 0.7～0.8, the net photosynthesis, hight, root weight, transpiration,chlorophyll conten of ginseng were higher than others, indicating that both lower and higher canopy density would reduce the rate of net photosynthesis of ginseng, and that the canpoy density of stand could be adjusted to satisfy the temperature and lighting for ginseng, and to provide the optimum ecology enviorment for the growth of ginseng.

结果表明，在生长季节内，林内温度低于林外温度，林下人参生长发育较差，产量较低；林分郁闭度为0.7~0.8时，人参的净光合速率、株高、单根重、叶绿素含量等指标较高；而郁闭度过高或过低都会影响人参生长发育；随着人参年龄的增加，净光合速率有逐渐升高的趋势。通过人为调节林分郁闭度的方式来满足人参对温度和光照因子的需求，为林下人参生长发育提供最适宜的生态环境。

VS crystallization, which has little effect on the elongation growth, takes place on side faces of the whiskers and consequently makes the whiskers radius increase.

从理论上可推导：晶须按 VS生长时，生长速度受原子沿晶须表面向晶须顶端的扩散控制，其生长速度恒定不变；按VLS生长时，固相与液相之间的 Gibbs Thom

The split between the two groups can hardly be papered over.
