20 cases of esophageal achalasia are treated with cardioplasty and total fundoplication designed by the Thoracic Department. Through Jan 1982 to July 1987 among the 20 patients treated no postoperative complications, gas blaot syndrome, gastroesophageal reflux and death occurred. The operation consists of cardioplasty, incising all the layers of the constrictive portion of the esophagus longitudinally and suturing transversally to relieve the dysphagia, and fundoplication to prevent postoperative relur.

20 cases of esophageal achalasia are treated with cardioplasty and total fundoplication designed by the Thoracic Department. Through Jan 1982 to July 1987 among the 20 patients treated no postoperative complications, gas blaot syndrome, gastroesophageal reflux and death occurred. The operation consists of cardioplasty, incising all the layers of the constrictive portion of the esophagus longitudinally and suturing transversally to relieve the dysphagia, and fundoplication to prevent postoperative relur. The clinical and experimental studies prove that this procedure fits the principles of surgical treatment in esophageal achalasia. A hard tube of 1-1.2cm in diameter as a trestle during fundoplication is used. Thus the lower esophageal sphincter pressures before and after operation are not statistically different.The operative method is described and the mechanism of antirelux is discussed.

本文报告了我科设计的贲门成形加胃底折叠术治疗食管失弛缓症20例的体会。通过临床观察,食管X线吞钡检查,食管动力学研究及酸性灌注试验等证实这种手术方法既可消除进食梗阻又可防止返流,操作也不复杂。文中结合临床和动物实验研究,讨论了胃底折叠的松紧度和这种手术抗返流的机理。

The driver circuit with vacuum-tubes and pulse transformers is still employed in thd TM-906 hard tube modulator with maximum pulse current of 400A and thd TM-702F of 50A. It is used to perform pulse coding or pulsewidth agility and to provide desired high voltage and large current. A solid state driver using silicon controlled rectifiers and power transistors is described, some problems concerned with application of bipolar power transistors to driver and their solutions are discussed.

The driver circuit with vacuum-tubes and pulse transformers is still employed in thd TM-906 hard tube modulator with maximum pulse current of 400A and thd TM-702F of 50A. It is used to perform pulse coding or pulsewidth agility and to provide desired high voltage and large current. A solid state driver using silicon controlled rectifiers and power transistors is described, some problems concerned with application of bipolar power transistors to driver and their solutions are discussed. Two practical circuits of novel structure and reasonable design are presented. Their volume, weight and cost are greatly reduced, and efficiency is increased.

到目前为止,在最大脉冲电流为400A的TM-906及最大脉冲电流为50A的TM-702F刚管调制器中,还沿用由真空电子管加脉冲变压器组成的预调器电路来实现脉冲编码或对在几种不同脉宽情况下工作的脉冲进行脉宽瞬时转换,提供所需要的高电压和大电流。本文介绍了用可控硅整流器(SCR)和功率晶体管组成的全固态编码预调器设计方案,叙述了双极型功率晶体管在预调器应用中的几个问题,讨论了这些问题的解决方法,给出了两种结构新颖和设计较为合理的实用电路,从而可大大缩小体积,减轻重量、降低成本和提高效率。

Hindolodes sporsuta Jacodi was first collected at Shaowu, Fujan Province in 1944 and the host plant was not recorded.The author discovered a large number of this insect in 1990 on the twigs of Celtis sinensis Pers. at Taigu,Shanxi Province.There is one generation per year. Winter is passed as the full-grown nymphs in the tubes constructed on the twigs of the host.In early April to May.The sex ratio is about 1:1.08. Females lay eggs on the surface of the fruits arranging in single line of 2 to 14 eggs....

Hindolodes sporsuta Jacodi was first collected at Shaowu, Fujan Province in 1944 and the host plant was not recorded.The author discovered a large number of this insect in 1990 on the twigs of Celtis sinensis Pers. at Taigu,Shanxi Province.There is one generation per year. Winter is passed as the full-grown nymphs in the tubes constructed on the twigs of the host.In early April to May.The sex ratio is about 1:1.08. Females lay eggs on the surface of the fruits arranging in single line of 2 to 14 eggs. Generally each female lays about 80 eggs. The egg stage is a month and the hatching rate may reach 82.8% There are 5 instars in the nymphal stage, the stadia are 18, 20, 30, 230 days, respectively.In June and July,the young nymphs construct calcareous helical tubes densely fixed on the petiole of fruit This tube is called "summer tube", In August, the 3rd instar nymph comes out of the summer tube and crawls the twigs, oil which they construct pale and hard tubes with the glue fluid from the anus The principal composion of the tube is calcium carbonate The nymphs develop in tube untill mature and emergece.The morphological characteristics of the pest are also describes.

朴平刺巢沫蝉HindoloidessparsutaJacobi模式标本采自福建邵武,寄主不详。生物学尚无详细报道。作者在山西太谷小叶朴树CeltissinensisPers.上发现其密度很大。1990—1992年研究结果表明:该虫寄主专一为小叶朴。一年发生一代,以老龄若虫在当年生枝上结钙质巢越冬。4月上旬,小叶朴发芽开花期,越冬若虫出蛰。成虫羽化期从4月中旬到5月。成虫雌雄比为1:1.08。每雌虫平均产卵量为80粒。卵产在小叶朴果实表面,成单列横排,一块有2-14粒,以8—10粒者为多,一果有1—4块;单粒卵为靴形。卵期约30天,孵化率82.8%。若虫共5龄,各龄历期分别为18天、20天、30天、30天、230天。6月和7月,幼龄若虫以排泄物在果柄上结夏巢,隐蔽巢内取食;8月份第3龄若虫退出夏巢,迁移到当年生枝上结冬巢。并在其中取食发育,越冬,直到翌年春末羽化为成虫。夏巢和冬巢均为螺旋形,蜗牛壳状,灰白色,质硬,化学成份主要为碳酸钙CaCO3。但夏巢远小于冬巢。对各虫期形态特征作了描绘。
