内形成性的

Moreover, the inner cone has the characteristic of Lewis basis with high electron density because of the lone-pair electrons of oxygen atoms stretching towards it and can form inclusive compounds with varied compounds. The special structure of CD is very important to separate and analyze enantiomers, which has become the most important mainbody of super-molecular chemistry and greatly improved the developments of bioscience and pharmaceutical chemistry.

环上具有多羟基，具有亲水性。O原子的孤对电子朝向内腔，使内腔具有高的电子密度，具有Lewis碱的特征，能和多种化合物形成包合物，这种结构因素在手性识别上起作用，目前它已经发展成为超分子化学最重要的主体，对促进生命科学和药物科学的发展具有重大意义。

Solid carbide tungsten fishtail drill is suitable for pcb flexible foil clad laminate,used for target machine drilling,the features of pcb fishtail drill are thin and flexible plate,it's structure and cutting methods are different with normal pcb drill bits.its two main cutting edge is concave and formed 100degree angle,in order to distinguish with PCB drill,named fishtail drill.fishtail drill cuts beginning of circular drill.concave along the main cutting edge to cut,chip is just two much fine filament.cuttingis falling off naturally,in order to be processed without burrformation by pcb surface.

整体硬质合金鱼尾钻适合印制电路板行业加工挠性覆箔板，为打靶机钻孔用。鱼尾钻所加工的印制电路板特性是薄板、带柔性、这样就决定了它的结构和切削方式与一般PCB钻不一样，它的两主切削刃是内凹的，两主切削刃形成100度的夹角，为了与PCB钻区别，就叫它鱼尾名。鱼尾钻切削时从我圆处钻尖开始，沿着内凹的主切削刃切削，切屑只是两条极细丝状切削，整个切削自然剥落，从而被加工印制板表面平整无毛刺。

There were many reasons attributed to this phenomenon: macromolecules, which were from raw material such as polysaccharides and proteins decomposed incompletely in the process, formed precipitation through biochemical reaction, many kinds of bacteria were not removed totally after fermenting, which caused bacterial precipitation, Fe3+ from fermenting equipments combined with polyphenol and proteins to form infusibility complex.

中文摘 要：食醋在其保质期内经常出现混浊现象，其原因主要有：原料中的大分子物质，如多糖、蛋白质等分解不彻底，后经过生化反应形成沉淀物质；发酵完成后，食醋中的各种微生物未及时清除，从而造成的菌体性沉淀；以及由于生产设备中的Fe3+与原料中的多酚、蛋白质等大分子形成的不溶性络合物所造成的沉淀。

Methods Three hundred cm-long ileus tube was installed into jejunum by nasal cavity under radiophotography observation in 25 cases with recurrent postoperative adhesive ileus,ileus tube was impulsed by enterokinesia to ileum end to relieve adhesive ileus and conduct internal intestinal arrangement.

25例术后反复黏连性小肠梗阻患者，X线监视下经内置金属导丝的引导作用将300 cm长的肠梗阻导管经鼻置入空肠屈氏韧带20 cm以远，即刻小肠内抽吸减压，导管前气囊充水形成水囊，模拟食团在肠蠕动的推动下在小肠内移行，带动导管边吸引减压边向小肠远端前行，到达梗阻的直接上部抽吸减压或通过黏连部至回肠末端全小肠减压，解除肠梗阻。

The results show that the dynamic change of water resources in the Heihe River Basin is mainly reflected by three aspects, i.e., the formation, utilization and disappearance of runoff respectively, the runoff formation area accounting only for 10% of total area of the Heihe River Basin plays a dominant role in the dynamic change of water resources in the whole basin and affects the capabilities of take-in and send-out, conservation, evapotranspiration and conversion of water resources.

研究表明，本区水资源动态变化主要在径流形成、利用和消失三个区域内具有依次性体现的特征。其中占总流域面积10%左右的河川径流形成区，对全流域的水资源动态变化具有先决性作用，并在各个区域水动态变化体现上又受到系统对水的吞吐、留存、蒸散和转化能力大小的影响。

Firstly,all patients have been excided the upper ductus choledochus,the liver gross duct,left right liver duct besides one centimeter of liver duct that lies upwards the hepatolith.Secondly, we have sutured the excided bile duct, which has been shaped acetabuliform,lifted one part of jejunums,intered non-port one subcuneously,and then inosculated gall with enteron by Roux-en-Y way.Lastly,we have partly excised the ill liver in regular way.Results 26 ones have been follow-up for 1～10 years.The rate is 81 percents,average for 6 years.

32例肝内胆管结石均接受皮下盲袢型胆肠吻合术，其中结石位于右肝7例（22%），左肝9例（28%），两肝均有16例（50%）；结石合并肝胆管狭窄24例（75%），全部病例均切开胆总管上部、肝总管、左右肝管，并切开肝内胆管狭窄部以上1cm肝管，将切开的胆管做必要的缝合，形成碟状，取一段空肠上提，盲袢埋置皮下，再做胆肠Roux-en-Y吻合，病肝做规则性肝部分切除术。

It is well known that retinal pigment epithelial cells are predominant proliferative cells in PVR which is an excessively wound healing response occurring after RPE cell wounding. The activated RPE cells migrate from their normal, sessile state to vitreous and onto both surfaces of the retina, in which they begin to dedifferentiate, migrate, proliferate, change phenotype and secrete ECM.

既往研究证明视网膜色素上皮(retinal pigmentepithelial，RPE)细胞是参与PVR的主要细胞，PVR是视网膜脱离后RPE细胞损伤的一种自我修复过程，是一种过度的眼内创伤修复反应；RPE细胞在正常位置上处于静止状态，而在某些病理条件下，如视网膜裂孔形成和视网膜脱离后，RPE细胞脱离原位，开始去分化、移行、增生、发生表型转化并分泌胶原等ECM，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。

Isolation and identification results of volatile compounds showed that aldehydes, alcohols and ketones were the major volatile compounds formed in the processing of XUANWEI ham, and had the highest relative contents in the 6-month-old, which were 11326.18, 947.29 and 554.95 μg nonane 100g-1, respectively. The result was relevant to intense hydrolysis of intramuscular fat in the pre-processed ham (4-month-old).

挥发性化合物的分离鉴定结果表明：醛、醇和酮类是火腿加工过程中形成的主要挥发性化合物，在6月龄时，它们的相对含量最高，分别为11326.18、947.29和554.95μg壬烷／100 g，此结果与加工前期（4月龄）肌内脂肪发生强烈水解相关。

The words "Pai-Chang"or "Pai5 Tiunn5" have many meanings But when used in traditional opera or music and explained as a kind of formal musical performance they are only applied in Taiwanese Peguan and Nanguan cultural circle particularly in Peguan circle There are two kinds of characters of "Pai-Chang" in terms of the function of the performance namely artistry and folk custom In Tainian city "Pai-Chang" which refers to the formal vocal performance without makeup and acting; nevertheless is used by the amateur actors' organizations of Peking opera as well Such a phenomenon raises two questions: first of all Although Peking the origin of Peking opera has vocal performance of Peking opera "Pai-Chang" is never used either artistry or folklore therefore how does this jargon hand down to the Peking opera circle in Tainan city ?

「排场」(pai5 tiunn5或ㄆㄞˊㄔㄤˇ)一词，用於戏曲音乐方面，做音乐的正式演出型态解释者，为台湾南北管文化圈所特有，其中又以北管最常使用。其以表演目的或弁郧荌粥洃嚏A可分为艺术性与民俗性两种。然而，在台南市及其周边的京剧文化圈内，亦使用有「排场」(pai5 tiunn5或ㄆㄞˊㄔㄤˇ)此一语汇，也指京剧的「正式清唱演出」。本研究动机基於对目前仅见於台南市及其周边之民俗性京调排场的两点疑惑：其一，按京剧的形成地－－北京，虽亦有京剧的清唱演出，然不论为艺术性或民俗性，北京人都不称为「排场」，那麼台南市京剧圈的排场语汇是如何得来的呢？代表了何种意义？

objective to study the changes of t-pa and t-pa inhibitorduring the acute stage of cor pulmonale.methods to measure the plasmatic activity of t-pa and pai by chrom-substrate in60cases of cor pulmonale,compared with the corresponding index of55cases in the control group.results pai was significantly higher in acute stage than in remission stage of corpulmonale,and t-pa was lower in remission stage than in acute stage.the difference was significant（p.01）.conclusion the unbalance between t-pa and pai can promote the formation of micro-thrombus and further exacerbate high pulmonary pressure.

目的 探讨血浆组织型纤溶酶原激活物及t-pa抑制物在肺心病急性加重期的变化。方法用发色底物法测定60例肺心病急性加重期的血浆t-pa及pai的活性，并与对照组55例肺心病缓解期的相应指标作比较。结果肺心病急性加重期患者pai显著高于肺心病缓解期，而t-pa低于肺心病缓解期，其差异具有非常显著性（p.01）。结论 t-pa及pai关系失衡，有助于动脉内微血栓形成，促进或加重肺动脉高压的形成。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.
