查询词典 aromatic plant

The results show that the torsion energy and van der Waals interaction energy are the main types of energy and the substitution group has a great effect on the total energy of molecular. The aliphatic substitution would lead to the increase of total energy, while the aromatic substitution would lead to the decrease of total energy. The calculated results of bond length show that the bond length of aliphatic C—C is longer than that of aromatic C—C, which indicates that the rupture of aliphatic C—C is easier than that of aromatic C—C on heating.

降低经营费用连锁经营企业以顾客自我选购、自我服务的经营方式为主，减少厂售货劳动，因而雇员相对较少，节省厂}一资成本，节约厂场地费用在连锁超市中，商品明码标价，顾客可以自由挑选，顾客节省厂购物时间，也节省厂企业的经营成本同时，加快厂顾客的流通速度，增加厂客流量总之，连锁经营与非连锁经营在总成本费用上的差距很明显我们对同样数量的两种企业进行抽样调查显示，连锁经营企业的费用较之其他零售商场约低10个白一分点

A field trial for plant density has been used for practical remediation in 2004 and 2005, it has four treatments, 10 cm×10 cm、20 cm×20 cm、10 cm×40 cm and 40 cm×40 cm, respectively. The results were follows: the optimization plant density was 20 cm×20 cm; Peteris vittata L. was a herbaceous plant fit to adequacy increased density for enhancing the biomass and removalling of arsenic; with increased the plant density, the plant were accumulated more proportion arsenic in their fronds, and then made promote the efficiency of arsenic removal from contaminated soils.(2) It was a complicated pyrolysis course for plant incineration.
