The study shows that weed density in paddy fields significantly decreases with more than 94% grass-controlling effect under SF compared with CK. Before rice booting stage, weeds compose mainly of Alopecurus pratensis, Echinochhloa crausgalli, Cynodon dactylon, Alternanthera philoxeroides, Mouochoria vaginalis, Murdannia triquetra and Eclipta prostrata in SF. During heading to ripe stage, weeds are mainly A. philoxeroides, E. crausgalli, C.

结果表明：规模稻鸭生态种养杂草密度显著降低，与水稻单一种植比较防效为94%；水稻分蘖到孕穗期稻田杂草主要由看麦娘、稗草、狗牙根、水花生、鸭舌草、水竹叶和鳢肠组成，抽穗期到成熟期主要由水花生、稗草、狗牙根和水竹叶组成。

CHALKER and Mark OWINGS (1945-), in The Index to the Science-Fantasy Publishers (1966; rev vt Index to the SF Publishers 1979; very much exp vt The Science-Fantasy Publishers: A Critical and Bibliographic History 1991), provides a checklist of almost every title released by the specialist sf houses, arranged by publisher.

乔克尔和马克。奥英斯的《科幻幻想小说出版者索引》（1966），再版名为《科幻小说出版者索引》（1979），扩充很多的版本更名为《科幻幻想小说出版者：评论和书目历史》（1991），提供了由出版业者准备的专业科幻出版社出版的几乎所有作品的目录。1991年的版本其内容十倍于初版，对使用者掌握20世纪科幻小说出版的情况提供了莫大的帮助——但是在细节上则有所欠缺。

Samples of conchocelis and gametophytic baldes of both SF-1 and Y-6 (isolated from SF-1 line) lines had a unique allele on PC40 locus, indicating that it can be used as a marker to distinguish these two lines from the others.

在引物PC-40界定的遗传座位上，2个优良品系申福1号和优质6号（以申福1号为母本选育出来的品系）的丝状体和叶状体均出现了区别于其他品系的等位基因，显示对这2个优良品系进行SSR特异性标记是可能的。

These moral issues were often quite responsibly examined in sf stories, but sf CINEMA tended to take a more simplistic line. The mid-1950s saw a procession of MONSTER MOVIES in which very often the monsters were the products of scientific irresponsibility; commonly a religiose voice, impressively baritone, would intone on the sound-track:"There are some things Man was not meant to know."

这些道德问题常在科幻小说中被太负责任的检验，而科幻电影采用简化的办法。20世纪50年代中期，排成行的怪兽电影中大部分的怪兽都是不负责任的科学产物；常常是一个狂热的声音——使人难忘的男中音——在声道中咏唱：&有些是人类不该知道的。&

Dactylon, M. triquetra. At tillering, species richness, Simpon index and Shannon-Wiener index are higher while Pielou index is lower in SF than in CK. From booting to ripening, weed species richness, Simpon index and Shannon-Wiener index are lower while Pielou index is significantly higher in SF than in CK.

研究还表明，规模稻鸭生态种养水稻分蘖期物种丰富度、Simpon指数、Shannon-Wiener指数略高于水稻单一种植，Pielou指数低于水稻单一种植；孕穗期到成熟期物种丰富度、Simpon指数、Shannon-Wiener指数低于水稻单一种植，Pielou指数显著高于水稻单一种植。

Degummed Bombyx mori silk was dissolved in a ternary solvent system of CaCl2/CH3CH2OH/H2O in 1∶2∶8 mole ratio at 60℃,and lyophilized SF was dissolved in 98％ formic acid to obtain regenerated SF solution for electrospinning.

将脱胶后的桑蚕丝溶解在摩尔比为1：2：8 的60℃CaCl2/CH3CH2OH/H2O三元体系中，将该溶液冷冻干燥后溶解在98％的甲酸中得到再生丝素溶液，对其进行静电纺丝。

Secondly, spinnability of SF dope was studied. The results indicated that the higher concentration of the dope and the less content of H2O would result in the better spinnability. And higher concentration of the dope had good spinnability whether the dissolution system containing minim EDTA or not. Pure EtOH and LiBr/EtOH (40/60, w/w) were used as solvent, to which minim EDTA was added. Then certain degummed SF was dissolved in the above mixed solvents to prepare the dope (21.7wt%) containing minim EDTA or not, respectively.

二、丝素溶液纺丝成型特性，结果表明纺丝液浓度较高及纺丝液中水分含量较少时再生丝素溶液有较好的可纺性，且无论体系中是否含有微量EDTA，较高浓度纺丝液均具有较好的可纺性，因此采用无水EtOH 及LiBr/EtOH (40/60，w/w)作为纺丝溶剂，制得了纺丝液浓度为21.7wt%含微量EDTA 及不含EDTA 的可纺性良好的丝素溶液。

Objective To compare MNA with MNA-SF in assessment of nutrition status of the elderly patients of chronic heart disease, and to comfirm the correlation of MNA and MNA-SF with classical nutritional assessment methods.

心血管疾病在住院老年病人中所占比例非常高，由于传统营养评价方法的局限性，此类病人发生营养不良往往得不到及时的发现和纠正。

The results of this reseach showed that administration of SF intracolonically had protective effect on the colon injury in the rat model of colitis induced by acetic acid enema, which was probably due to the mechanism of antioxidation, inhibition ofarachidonic acid metabolis and platelets activation, administration of SF intracolonically also showed protective effect on the colon injury in the rat model of colitis induced by trinitrobenzene sulfonic acid and ethanol, which was probably due to antioxidation and inhibition of macrophages activation.

实验研究表明，大鼠分别经乙酸、TNBS和乙醇处理后均出现典型的结肠炎症状，给药后分别评价结肠粘膜损伤指标、结肠组织病理变化，检测结肠组织炎症指标、结肠组织氧化损伤指标及主要炎性细胞因子改变；实验结果：阿魏酸钠对大鼠乙酸性结肠炎结肠粘膜损伤具有缓解保护作用，其机制可能与直接抑制炎症结肠粘膜花生四烯酸代谢过度，抑制血小板活化，清除大量氧自由基有关；阿魏酸钠对大鼠TNBS性结肠炎粘膜免疫损伤亦具有缓解保护作用，其机制可能与抗氧化，抑制结肠巨噬细胞活化有关。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。
