Reduction of ovule number as a tendency of speciation in the genus is substantiated by the occurrence of tri_ovulate cones coupled with comprehensive characters of the genus. The metamorphic patterns as well as the leaf nature of the outer envelope indicate that female cones of Ephedra are compound while the female reproductive units of the ovulate cone have been reduced from secondary reproductive shoots similar to those of cordaites by phylogenetic transformation, fusion and reduction. Each fertile bract together with its axillary female reproductive unit composed the Bract Scale and Seed Scale Complex of Ephedra .

基于返祖性畸形三胚珠球花的出现及其他形态特征，认为麻黄属胚珠数目减少是该属内物种特化的一个趋势；利用雌球花发育的畸形现象及外珠被的形态学本质提出麻黄属的雌球果为复轴性构造，雌性生殖单位是由类似于科达类的次级生殖枝构造经系统发育变态、融合、简化成现存的生胚珠构造式样，每一可育苞片及其腋内雌性生殖单位共同组成了麻黄属的苞鳞_种鳞复合体。

Experimental results indicate that the reduction of chemical oxygen demand were 40%, 38%, 12%, 50%, and 73% for β-naphtho1, salt R, dihydroxy salt R, acid red, and wastewater, respectively when the reactions had run for 4 h at a pH of 1.7. In comparison, the COD reduction of-naphtho1 and salt R were 10.2% and 16.2%, lower than 23.4% and 18.1% with H2O2, while the Fenton reaction time was 1 h.

当pH=1.7、反应4h时，β-萘酚、R盐、二羟基R盐、酸性红、实际废水的化学需氧量去除率分别可达40%、38%、12%、50%和73%；对比实验显示，反应时间为1h时，β-萘酚和R盐的COD去除率分别为10.2%和16.2%，而用H2O2则分别为23.4%和18.1%。

Taking Shewanella and Geobacter as examples, this paper reviewed three kinds of possible mechanisms of microbial enzyme-catalyzed dissimilatory Fe reduction and its molecular regulation, i.e., direct contact between microbial cell and Fe oxides, siderrophores, and electron shuttling compounds. Many membrane-bound cytochrome proteins are involved in the dissimilatory Fe reduction, forming a complicated regulation network.

以希瓦氏菌和地杆菌为例，本文综述了3种异化Fe还原的酶促反应机制及其分子调控机理：异化Fe还原菌与Fe氧化物直接接触机制、电子穿梭体的作用机制、铁载体作用机制，多种膜蛋白特别是多血红素的细胞色素蛋白参与微生物的异化Fe还原过程，并形成复杂的调控网络。

The mechanism of electrocatalytic reduction, the classification and selection of electrode and catalyst and the effect of temperature, current density and pressure on the selective and Faradaic efficiency of reduction are discussed.

介绍了在水溶性介质中利用电化学催化的方法还原CO2的研究现状：电催化还原机理、电极材料催化剂的分类和选择；综述了温度、电流密度以及压力等对还原选择性和法拉第效率的影响；展望了CO2电催化还原方法的研究方向和应用前景。
