The dynamic behaviour of copper was investgated making use of an ex-perimental Lagrangian analysis technique,in which multiple manganin gauges were used to measure the stress-time history at different Lagrangian positions in the stress wave field,and a modified pathline method was used to analyse and solve the dynamic and physical parameters of the flow field.

利用拉氏分析方法对钨合金在高应变率下的力学性质进行探讨，分析各拉氏位置的应变，比容，密度，应变率，比内能，质点速度等物理量的变化历史，讨论不同晶粒度尺寸对钨合金在高应变率下动态力学性能的影响，给出钨合金在应变率为104~105s-1时的应力应变曲线。

During remediation experiment, the addition of benzene acid and Tween 80 gave higher CO2 evolution. The result of Microtox assay showed good correlation between aromatic rings of PAHs at low concentration. The Medaka embryo toxicity test had presented that while eggs were exposed to the soil extracts from fluoranthene and pyrene at high concentration (3mg PAHs/g soil), the embryo showed low hatch ratio、bleeding, high abnormal ratio and delayed mature period. The addition of composting materials for remediation study showed strong embryo toxicity to Medaka embryo at all test concentration.

青鱂鱼鱼卵试验部分，受单一与混合PAHs污染土壤之萃取物对青鱂鱼鱼卵孵化影响，当暴露在浓度3 mg PAHs /g soil时，及四环的Fluoranthene与Pyrene之下，皆有高未孵化率、高出血率、高畸形率及孵化天数的延迟现象产生；而在复育实验之土壤萃取物对青鱂鱼鱼卵孵化之影响，以添加酸性界面活性剂与中性界面活性剂实验组其鱼卵之未孵化率皆为零，与Microtox毒性测试结果有良好的关连；加入不同复育添加剂中，则以添加菜肥之实验组，对於青鱂鱼鱼卵孵化之影响为最大。

Results The rates of successful embolization for anteriorly directed aneurysms and for superiorly directed aneurysms were 91.6% and 73.3%, respectively, but that for inferiorly directed aneurysms was only 50.0%.

On the basis of the laboratory data and by widely analysing the formation origin and mechanism of low-resistivity oil/gas reservoir, a point of view is put forward which is not consistent with the idea existing for a long time, that is not all the low-resistivity oil/gas reservoir is shaly sandstone. Fine grains or pure fine siltstone can also form the low-resistivity oil/gas reservoir. And the additional conductibility of clay will become the prominent factor that causes the low-resistivity only when the salinity of formation water is lower. Actual cases indicate that when the salinity of formation water is greater than 300000ppm or so, even ifthere is some clay, its additional conductibility can also be ignored.

建立在实验室数据的基础之上，并通过广泛地低电阻率油气储集层成因和机理分析，提出了与长期以来存在于人们头脑中的思想观念不相一致的看法，即认为低电阻率油气储集层并非都是泥质砂岩，岩石颗粒细小的或纯净的细粉砂岩也可能形成低电阻率油气储集层，并且粘土的附加导电性也只有在地层水矿化度比较低时，才会成为造成低电阻率的突出因素，事实表明，当地层水矿化度高于大约300000ppm时，即使储集层含有一些粘土矿物，它所产生的附加导电性也是可以忽略的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
