1. In order to study the impact of heavy metals on Pirate subpiraticus, 50 soil samples and 150 individuals of P. subpiraticus were collected from 5 different habitats in Nanyang City, Henan Province in July 2008. The contents of heavy metals of soil and P. subpiraticus were measured using atomic absorptions pectrometry. The carapace width, female weight, egg sac weight, the volume and number of eggs were measured and counted.
为了探明重金属含量对拟水狼蛛Pirata subpiraticus生物学特性的影响，本研究于2008年7月在河南南阳地区5种不同生境下，共采集50份土壤样本和150头拟水狼蛛样本，采用原子吸收光谱法测定了5种不同生境下雌拟水狼蛛体内重金属含量，并测定了雌蛛头胸甲宽、体重、卵袋重最、卵数目和卵体积等生物学指标。
2. PROFESSOR: five & there''s five valence electrons, but the atomic number is actually seven.
教授：5，有5个价电子，但原子序数是7。
3. The cells in the blank control group were cultured for 24 hours. Particle diameter was measured using atomic force microscopy; morphology was observed using electron microscope; effect of different concentrations of graphite carbon nanoparticles on cell number was detected using hemacytometry under optic microscope; the effect of 7.5 mg/L graphite carbon nanoparticles on ultramicrostructure was observed under transmission electron microscope.
