Without these phenomena, can disconnect the output side of the current transformer and DC side of the Hall Voltage Sensor current detection, reset after the operation to see if there were flow phenomenon.

如果没有这些现象，可以断开输出侧的电流互感器和直流侧的霍尔电流检测点，复位后运行，看是否出现过流现象。

The findings indicate that, on the whole, the pattern of load transfer curves of adfreezing stress on a steel pipe pile stem and that of resistance stress on the pile tip are parabola and straight line, respectively; Due to the rheology effect, to different extent, adfreezing stress on the pile stem and resistance stress on the pile tip vary with time and relative displacement of pile-soil, respectively, and the settlement of pile tip varies with time tempestuously within 5 hours of loading, and then approximates to stability.

结果表明：模型钢管桩桩侧冻结力荷载传递函数曲线及桩端阻力荷载传递函数曲线其线状大致分别程抛物线及直线；由于流变效应的影响，桩侧冻结应力及端阻应力随时间有不同程度的变化；桩土相对位移和桩端下沉量开始5h内随时间变化较大，但加载5h后逐渐向稳定方向发展。

The abdominal wall in the left lower quadrant, 2 finger breadths (3 cm) cephalad and 2 finger breadths medial to the anterior superior iliac spine, has been shown to be thinner and with a larger pool of fluid than the midline and is usually a good choice for needle insertion for performance of a therapeutic paracentesis.27 The right lower quadrant may be a suboptimal choice in the setting of a dilated cecum or an appendectomy scar.

在过去，常常将腹部正中线耻骨与肚脐中间定为穿刺点，现在，由于腹腔穿刺引流大量液体以及腹中部脂肪厚度增加，左下腹成为腹腔穿刺部位（表1），在左下腹部中线至髂前上棘连线上2指宽（3cm）与距髂前上棘2指宽，已经显示较中部脂肪少及腹水较多是治疗性腹腔穿刺好的首选部位27，在盲肠有扩张或阑尾切除术后瘢痕时右下腹是次选的穿刺部位，应避开腹壁下动脉，这些血管走行在耻骨与髂前上棘之间的中线然后在腹直肌中向上行走，，腹壁可见的侧支循环亦应该避开，腹腔镜检查发现侧支循环可出现在中线并且在腹腔穿刺时有导致血管破裂的风险28。

Afterwards of pelvic cavity abscess is sent at abdominal 2, palace antrum operation 1, celiac lens operation afterwards of 7 years old of little patients sends exemple of a;1 at acute appendicitis, abscess is formed all round appendix. 24 patients all have issue abdominal durative secret anguish or bilge painful, among them 18 have clonic aggravate, companion has frequent micturition, make water urgent, make water is painful wait for bladder to stimulate vagina of semiotic;10 exemple to shed secretion of yellow pus appearance, 5 have the vagina irregular bleed. 19 appear calorific of temperature 38~42 ℃, next 20 abdominal tenderness, bounce painful, flesh is nervous, the person that accessories division has touch a tender spot 22, among them side of 15 Yu Shuang, 7 touch at odd side bag piece.

盆腔脓肿继发于开腹手术2例，宫腔手术1例，腹腔镜手术1例；1例7岁患儿继发于急性阑尾炎，阑尾四周脓肿形成。24例患者均有下腹部持续性隐痛或胀痛，其中18例有阵发性加剧，伴有尿频、尿急、尿痛等膀胱刺激症状；10例阴道流黄脓样分泌物，5例有阴道不规则流血。19例出现发热(体温38~42℃)，20例下腹部压痛、反跳痛、肌紧张，附件区有触痛者22例，其中15例于双侧、7例于单侧触及包块。

"Either the Atlantic or the Pacific subspecies of Clupea harengus (once considered two separate species), slab-sided, northern fishes that are small-headed and streamlined, with silvery iridescent sides and a deep-blue, metallic-hued back."

鲱形目鲱科体形侧扁的北方鱼类，既指大西洋鲱，也指太平洋鲱(C.harengus pallasii)，两者曾被认为是两个种，现则仅作为两个亚种。鲱鱼头小、体呈流线形，体侧闪亮银色，背部深蓝金属色。

（1）Bullae of lung ruptured spontaneous pneumothorax is the best indication for VATS,which has the advantages of less trauma and ache,short operation time,quick recovery and small incision;（2）Recurrent unilateral spontaneous pneumothorax with contineous air leakage of 7 days after closed thoracic drainage,bilateral spontaneous pneumothorax should be treated by VATS;（3）Spontaneous pneumothorax with pleura adhesion can be treated by pneumonolysis and bullae of lung excision under thoracoscopy assisted small incision operation.

疗效满意。结论：（1）肺大泡破裂自发性气胸是胸腔镜手术最佳的适应证，与传统开胸手术相比，胸腔镜手术具有患者创伤小，手术时间短，术后疼痛轻，康复快，符合美容要求等特点；（2）反复发作的单侧自发性气胸，行胸腔闭式引流术后持续漏气7d，双侧自发性气胸，不论是否同时发作都可考虑胸腔镜手术治疗；（3）自发性气胸并胸膜粘连可用胸腔镜辅助小切口行粘连松解肺大泡切除术；（4）为减少一次性材料的消耗，降低手术成本，可辅助小切口使用常规胸科手术器械完成手术；（5）为减少术后复发率需行胸膜固定术。

The results show that in the formation process of tumble during the intake stroke,two vortexes are generated in the cylinder.

增加流经排气门侧的进气气流或抑制直接沿进气门侧缸壁流入气缸的气流，都能提高滚流强度。

In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.

对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
