Abstract］ Objective We assessed the usefulness of a laparoscopic Heller myotomy with a Toupet fundoplication for the treatment of achalasia.Methods LHT was performed in 30 patients who had esophageal achalasia with severe dysphagia.

摘要］ 目的评价腹腔镜Heller术合并胃底折叠术治疗贲门失弛缓症的疗效方法 30例伴严重吞咽困难的贲门失弛缓症的患者实行了LHT。

The mass transter can be enhanced ,when we introduce sulfuric acid and cuprous oxide into this system.The model is formed to describe the transference of the martial between the four phases: gas-liquid-liquid-gas, which can explain some problems. We analyze the dead of the catalyst, and make a conclusion that the surface of the catalyst is covered with some compounds such as bluestone, which lessen the activity points of the catalyst and debase the activity.

在SO_4~(2-)／ZrO_2-La_2O_3催化的反应系统中加入稀硫酸和氧化亚铜促进了异丁烯和一氧化碳的传质、使反应得以快速，高选择性的进行，异丁烯的转化率达95％以上，特戊酸的收率达47％；讨论了g-l-l-s传质过程；对催化剂作了失活分析，催化剂失活的原因是因为反应后的催化剂表面覆盖了一层硫酸盐，使催化剂的活性中心数减少，活性降低。

The the accurate effective length factors of gable portal frames are got. The paper also found the unbraced low height-span ratio gable portal frames can produce the non-sway buckling, and the reason of non-sway buckling are given.

并在分析中发现高跨比较小(小于1/5)的山形门式刚架在无侧向支撑的情况下能够发生无侧移失稳，分析了山形门式刚架发生无侧移失稳的原因。

Cases were considered as heterozygous if PCR amplification of undigested DNA showed two major bands with equal intensity. Cases with only one major band were homozygous for HUMARA and thus uninformative.

2·讨论一、克隆状态分析与HUMARA分析在胚胎发育早期，女性体细胞的两条X染色体中，随机地有一条发生失活，因此正常女性组织的X染色体失活方式为随机性。

The influence of disability glare is decided by the Equivalent Veiling Luminance and average road luminance.

失能眩光是由于眩光源在人眼屈光介质内形成散射而形成的，可以通过等效光幕亮度和路面平均亮度来确定失能眩光的影响大小。

However, the role of inactivation gate of sodium channel is not clear. In present study, single fibre recording in vivo from dorsal root on chronically compressed DRG model was used. We analyzed the characters of ISI series of oscillation firing of type A neurons induced by veratridine, an inhibitor of inactivation gate of sodium channel.

本研究在大鼠背根节慢性压迫模型上，利用在体单纤维记录方法，观察与分析Na通道失活门抑制剂藜芦碱引起受损背根节A类神经元放电ISI序列发生的变化特征，为了解Na通道失活门与放电型式的关系以及进一步探索放电时间型式与疼痛的关系奠定基础。
