Meanwhile, the concentration of Pb,Zn and other heavy metals is rather high in the oxidation zone and decreasesdownward to levels that are unbelievably low for Pb-Zn mine tailings. Theseobservations suggest that heavy metals should be re-immobilized by secondaryminerals, rather than primary minerals, in the oxidation zone, and could be leachedout from suboxic environment due to low rate oxidative dissolution which preventsthe precipitation of secondary minerals in significant amount. Thus, cover scenarioswhich establish a suboxic environment beneath the cover layer might not always beeffective in preventing heavy metal release from mine tailings.Sequential extraction studies indicate that, in addition to heavy metal leaching,oxidation of the mine tailings increased the mobility of residual Zn, and Cu, while Pb remains immobile due to the formation of anglesite (PbSO4). Using the seven-step extraction technique developed by Dold (J. Geochem. Explor., 2003, 80: 55-68), galena dissolves in significant amount at step 2 most probably due to the strong complexing of Pb2+ by acetate, while other metal sulfides dissolve at step 6, which suggest that this extraction technique could not be used to evaluate the mobility of lead in natural environment

重金属含量均低于新鲜尾矿，但以硬化层中的含量最高(Pb、Zn含量分别为0.47%和0.93%)，往下大幅度降低，表明尾矿风化过程中形成的次生矿物对Pb、Zn等重金属元素有较强的固定作用，而次氧化带的淋溶作用造成了金属元素的大量流失；(4)与新鲜尾矿相比，硬化层中铅的可迁移性大大降低，硬化层之下尾矿样品中铅的可迁移性也不同程度降低，这是由于硫化物氧化产生的硫酸根与尾矿中的铅反应形成铅矾(PbSO_4)的缘故；(5)氧化作用使尾矿中的zn、Cu等重金属的可迁移性不同程度地增大，其中对锌的可迁移性影响最大，铜的可迁移性与铁比较相似，铅则容易与硫化物氧化形成的SO_4~(2-)反应形成铅矾(PbSO_4)；(6)为了减少尾矿污染和修复矿山环境，人们提出了各种不同的尾矿覆盖方案，本文的研究结果表明，这些方法不一定能够有效地阻滞污染元素的迁移。

Some day, when the world is much older, and when mankind will be masters of all the destructive powers in nature, to serve for the general good of humanity; when mankind, as you were just saying, have discovered the secrets of death, then that death will become as sweet and voluptuous as a slumber in the arms of your beloved.

死，按照我们处理它的方法的好坏，可以成为一个朋友象护士轻轻地拍我们入睡一样，也可以成为一个敌人，象一个粗暴地把灵魂从肉体里拖出来的敌人一样，将来有一天，当人类再生活上上千年，当人类能够控制大自然的一切毁灭性的力量来造福人类的时候，象你刚才所说的那样，当人类已发现死的秘密的时候，那时，死亡就会象睡在心爱的人的怀抱里一样甜蜜而愉快。

In these portion,the article begins the study of tone sandhi from the point view of two-character phrases and three-character phrases,which is also the focus and difficult point as well.On the basis of substantial materials of Dingzhou dialect,the author elaborates its rules and principles of tone sandhi of the general phrases and those with light tones,and reiterative location.the author puts his views as follows: 1.The rules of tone sandhi of two- character phrase are simple and unitive. 2.The complex of the phrase with light tones lies in the combination of the first tone and light tone.In the case,there are two different pronunciations in Dingzhou dialect.The author guesses it is the coexist of ancient pronunciations and common spoken Chinese. 3.The tone sandhi of general three-character phrases on the basis of the rules of that of two- character phrases,using the grammar structure of the three-character phrases as the restricted conduction,which function jointly. 4.The rules of tone sandhi of three- character phrases with light tones are restricted only by that of the two- character phrases with light tones and thus are foreign to grammar structure. 5.The tone sandhi of the words with reiterative location has their own system.

这两章中，作者采用直接调查法，社会语言学方法分别从一般字组、含轻声字组和叠音词字组三个方面对定州方言连读变调进行详尽地描写，文章中既有对连读变调的共时性描写，也有对连读变调历时性推测，总的来讲笔者认为定州方言变调具有一定的系统性，主要表现在以下几个方面：两字组连读变调规律简单统一，含轻声字两字组内部规律较为复杂，但是具有很强的一致性；定州方言含轻声两字组变调的复杂性主要表现在阴平+轻声的组合中，在这种情况下，定州方言有两种读音方式，推测它是语音存古现象和普通话语音并存的结果；一般三字组连读变调以两字组连读变调规律为基础，以三字组的语法结构为制约条件，二者共同发生作用；轻声三字组变调规律只受轻声两字组变调规律的制约，与语法结构无关；叠音词的变调规律自成系统。

Theoretical Part: Through theoretical analysis of chemothermodynamics, combustion and engineering thermodynamics, factors that affect explosion limit were determined, which include temperature, pressure, spark ignition energy, electrode shape, direction of flame propagation and size of explosion vessel.

理论部分：根据化学热力学、燃烧学和工程热力学的基础理论，从本质上定性地分析了爆炸极限的影响因素，包括温度、压力、爆炸容器的大小、点火能量大小、以及火焰传播方向等，得出了这些影响因素对爆炸极限的影响规律，以确保实验有完整的理论基础指导；在此基础上本文提出了一种新的推算在常温常压下可燃性纯质和混合工质制冷剂爆炸极限浓度的理论方法，该方法由可燃性气体的化学组成来推算上下限浓度，不需要其它条件；对混合工质制冷剂，只要再知道混合配比，即可以推算出爆炸极限，使预测爆炸极限的工作更简单、方便。

objective:to investigate the therapeutic action of somatostatin in pancreatic leakage after pancreaticoduodenectomy.methods: to collect 100 patients with pancreaticoduodenectomy during 2003～2006,contrast 44 patients use somatostatin after pancreaticoduodenectomy as experimental group,and 56 patients with conventional therapy as control group.results:there were no pancreatic leakage case in the modified group of 44 cases.3 cases complicating pancreatic leakage occurd in control group,and the proportion of pancreatic leakage are different examined by statistic mathord.conclusions:use somatostatin after pd can restrain organism excrete diastase vera,and help anastomotic stoma to concrescent and decrease pancreatic leakage;pancreatic leakage should be treated by different grades,grade 1 can be cured by persistent drainage with somatostatin and nutritional support;grade 2 should be pay more energetic intervention.

作者单位：潍坊医学院，潍坊 261042；潍坊市人民医院肝胆外科，潍坊 261042 目的：探讨生长抑素在胰十二指肠切除术后减少胰漏的作用。方法：收集2003年1月～2006年12月施行pd患者100例，术后应用生长抑素持续泵入病人44例，并与同期施行的pd术后常规应用全肠外营养及抗生素治疗病人56例，结果进行了对比观察。结果：实验组病人44例无1例发生胰漏，对照组56例病人，3例发生不同程度的胰漏，发生率5.3%，统计学比较有显著差异（p＜0.05）。结论： pd后应用生长抑素持续泵入可以抑制胰酶的作用，使胰肠吻合口较好地愈合，从而有效地减少胰漏的发生；胰漏可进行分级治疗，ⅰ级胰漏采用通畅引流为主，同时使用生长抑素和营养支持等治疗多可治愈，ⅱ级胰漏需要积极治疗。
