I mean, there's no cop in of mice and men.

我是说，在人与鼠里没有警察。

For the vegetative shoot, the reproductive shoot, the coppice shoot, PN, WUE, VPD and E increased with the increasing of CO_2 concentration, the increasing of PN was larger than that in E.

营养枝、繁殖枝和萌生枝条的PN，WUE，VPD及E均随CO2浓度升高而增大，PN增加幅度较大，E增加幅度较小。

The relatively proper relation was also determined between the reserved coppice shoot quantity and the density.

结果表明，母桩高度在一定范围内对萌条量影响不大，而母桩地径与萌条量关系密切，并确定了较适宜的留萌条数量与密度的关系。

On the sites with middle and deep soil layers the recommended rotation age of oak coppice system is 3-5 years.

在土壤为中层-厚层厚度的条件下，栎林矮林作业轮伐期以3～5a为宜。

The results showed that owing to better layers composition and more litters and roots, abilities of holding water and preventing erosion of Oriental oak forest, Black locust forest and coppice forest of Black locust are stronger than that of others.

研究表明，栓皮栎林、刺槐林和矮刺槐林具有较好的层次结构、较大的枯落物积累量及根系数量，保水防蚀能力较强；

With a discounting rate not less than 12%, the investment on the coppice forest manage-ment on the ⅲ land site is not reasonable;

贴现率不低于12%时，在（？）立地级经营刺槐萌生林是不合理投资；

Under same growth conditions, there would be relative higher volume and productivity in coppice forest than in seedling crop of Robinia pseudoacacia.

与实生林相比，在相同的生长条件下，萌生林具有较高的木材量和生产力。

And the rotation age at the 8th to 13th years was reasonable for coppice forest management of black locust.

以培育干材和小径级矿柱材等工业用材为目的，对刺槐萌生林实施8～13a短轮伐期作业法，从经济效果最佳角度考虑是比较合理的。

The results showed that no benefit would be derived from black locust coppice forest with a rotation age beyond 20;

研究结果表明；以20a以上的轮伐期经营刺槐萌生林在经济上是不合算的；

Preliminary study on Coppice Forest of Robinia pseudoacacia

刺槐萌生林的初步研究

Various factors affecting the slow-crack-growth ( SCG) resistance of ethylene copolymer ( denoted as polyethylene below) pipes were investigated, including the content, type, and their distribution on the backbone of the comonomers, as well as the molar mass of polyethylene.

研究了共聚单体的种类、含量以及相对分子质量、共聚单体支化链在主链上的分布等因素对聚乙烯管材料抵抗慢速裂纹扩展（SCG）性能的影响。

Results indicate that the addition of right amount of PBT with low viscosity, ethylene copolymer A, rosin ester A and rosin ester B could improve the flowability of the composites to some extent without loss of their good mechanical properties and flame retardancy.

结果表明，适量加入低粘度PBT、乙烯共聚物A、松香酯A、松香酯B可使体系在保持综合性能较好的前提下，流动性能得到不同程度的改善。

A kind of vinyl acetate ethylene copolymer emulsion was prepared. With a viscosity range from 3 300 to 4 500 mPa · s.

介绍了一种粘度在3300～4500mPa·s之间的醋酸乙烯-乙烯（VAE）共聚乳液的工艺制备方法。
