objective to study the ct diagnosis of ureteral calculus at the distal end of ureter.methods 82 cases of ureteral caculus were examined by ct scanning.all cases were proved by clinical therapeutic results.results ureteral calculuses were showed as high density image in ct scanning.the ct values of the ureteral calculuses less than 7.5mm in diameter were beyond 83hu.the detection rate by ct was 96.3%.in all the 82 cases,ureteral with calculuses were found dilated and 69 cases with nephrohydrosis.in 13 cases with no nephrohydrosis,caculuses less than 3.8 mm in diameter were found.conclusion ct is the most valuable way to diagnose ureteral calculus at the lower end of ureter.appropriate methods of ct scanning are essential.

目的 回顾性分析输尿管膀胱入口处结石的ct诊断结果，评价其ct检查的临床应用价值。方法分析82例输尿管膀胱入口处结石的ct检查结果，所有病例均经尿道排石证实。结果输尿管膀胱入口处结石具有特征性的ct表现，即圆形或枣核状钙化高密度影，结石直径＜7.5mm，ct值≥83hu，ct确诊率96.3%。82例均发现病侧输尿管增粗，69例发现病侧肾盂少量积水，肾盂未见积水的输尿管膀胱入口处结石13例，其结石直径＜3.8mm。结论 ct检查输尿管膀胱入口处结石具有准确、无创、直观等优点，是诊断输尿管膀胱入口处结石不可替代的检查方法。

The method comprises heating up the lactic acid solution to gasify at 150-200 degree C, mixing the obtained mixed vapour of lactic acid and water with the carrier gas, entering into gas-solid catalytic reactor to get the reaction product gas by the action of a modified Y zeolite molecular sieve catalytic agent and dewatering after heating up the mixed gas to 200-450 degree C, obtaining the propenoic acid solution through gas-liquid dissociation after cooling the reaction product gas, obtaining coarse propenoic acid products form the propenoic acid solution by gas stripping, azeotropic distillation, extraction and rectification in turns.

其特征在于将乳酸水溶液加热至150～200℃气化得到的乳酸-水混合蒸气与载气混合，将混合后的气体继续加热到200～450℃后进入气-固相催化反应器中经改性Y沸石分子筛催化剂作用脱水得反应产物气体，反应产物气体冷却后经气液分离得到丙烯酸溶液，丙烯酸溶液再依次经过气提、共沸蒸馏或萃取、精馏得到粗丙烯酸产品。

Furthermore, large-scale fold and fault structure hasn't been found around the Tianchi Lake, but the original prismatic joints and radial joints developed well in the trachyte, so the rock mass is dissected into fractured fragmental structure and the integration of rock mass is further destroyed.

在构造方面，长白山天池周围虽然没有发现大规模的褶皱断裂构造，但粗面岩中原生柱状节理、放射状节理十分发育，这些节理裂隙将岩体切割成十分破碎的碎裂结构，使岩体极易产生岩崩、落石，使岩体的完整性遭到了进一步的破坏。
