破口

The result demonstrates accent of true and false in 34 AD 34, inside diaphragm 27, the haematoma inside the wall interlining of model of 7;27 exemple is three-dimensional into resemble all showing clear crevasse, crevasse of aorta bend ministry with arrowy shape show optimal, fall aorta crevasse shows with position of axle and coronal shape optimal, VRT shows pathological changes whole journey is clearer, but reach to crevasse inside the indication of diaphragm reachs position of axle as MIP, MPR.

结果34例AD中显示真假腔34例，内膜片27例，壁内血肿7例；27例典型夹层三维成像均显示明确破口，主动脉弓部破口以矢状位显示最佳，降主动脉破口以轴位及冠状显示最佳，VRT显示病变全程较清楚，但对破口及内膜片的显示不如MIP、MPR及轴位。

For example, only one or two hemomediastinum at the edges, you can use adhesive tape, and for one more layer of hemomediastinum that you can use the faoyuan along the longitudinal utility knife with a long fillet, avoid stress concentration causing breaking.

比如只有一两处纸边破口，则可用胶纸贴好，而不不差于一处众层的破口，可用美工刀沿纵向划一个较不幼的功渡圆角，制止由于答辛集洋变成断裂。

If you live your brokenness under the curse, even a little brokenness can destroy your life.

如果你的破口使你生活在诅咒下，即便一个小小的破口都能摧毁你的生活。

If a copy of the book with the above mentioned five factors of an issue in the hours'work more cut-copies you wish to generate back-hemomediastinum, the greater the chance of butshe, producing a spine hemomediastinum dextrality.

如果每册书带有以上提到的5个不败不合洋的一个题目，那么屡屡裁切册数越众，爆发书脊破口的几率不离越不小反之，爆发书脊破口的几率不离越众。

The analytic results obtained from the PCT evaluations revealed that the most limiting accident was the case with a break at the Main Steamline Outside Containment. Its PCT was 1289.15 ℉, which is much below the upper temperature limit of 2200℉ set by the nuclear regulatory authority. The most limiting accident for the minimum water level measured outside the core shroud is the case with a break at the High Pressure Core Flooder Line, the minimum water level drops to 18.4 ft. For this case, even though the water level has dropped to 11.6 ft below the top of the active fuel, the reactor core was still completely covered by the two-phase water.

分析结果显示，对燃料护套最高温度而言，最严重之事故为围阻体外主蒸汽管路破口，其燃料护套最高温度为1289.15 ℉，此温度远在法规10CFR50.46所定之限值 2200 ℉以下；对反应炉最低水位而言，则最严重之事故为高压注水系统管路破口，反应炉降水区最低水位降至18.4 ft，约在有效燃料顶部以下11.6 ft，然而炉心内部仍为双相饱和流体所完全覆盖。

Talking a typical Westinghouse three-loop pressurized water reactor as reference plant and using the PWR severe accident analysis platform based on RELAP/SCDAPSIM code, best estimate calculation of hot leg large break LOCA of 25 cm without mitigating measures is performed. The mitigating capability of high-pressure safety injection to the accident is studied when peak core temperature reaches 1100 K, 1300 K and 1500 K respectively.

以西屋公司典型的三环路压水堆为参考对象，采用基于RELAP/SCDAPSIM程序开发的压水堆严重事故分析平台，对没有缓解措施的热段25 cm大破口失水事故进行了计算分析，详细研究了堆芯表面峰值温度分别达到1 100K、1300 K和1500 K时进行高压安全注射对大破口失水事故的缓解情况。

Results MPR images were helpful in diagnoses of the low density intimal flap,the entrance,the true channel and flase channel,CPR can show the whole disorder;VR was good in showing whole aorta stereoscopically,although VR was superior to others in display details in the aorta lumen.

结果：MPR对判断真假腔、内膜瓣、破口入口有帮助；CPR显示主动脉夹层动脉瘤整体效果较好；VR整体观最好，但显示内膜瓣、破口入口不如前两者。

Hand-folded four-Pack (50g/mdoes-quadratical and the following paper) or hand-fold three fold (60-80g/m-squared paper) in a manner worthy of the books which should be in the book-to-last three fold in a manner worthy of the fold sewup hemomediastinum, to rule out the air and in a manner worthy of the book to prevent wrinkles appear, but now there are many flats in manual folding, knowing very well that should be hemomediastinum, but the pursuit of production would go for the big is not hemomediastinum, and finally after the wrinkles in buchbinderei and unrectifiable is extremely serious.

手工折四折（50g/m平方及以下的纸张）或手工折三折（60-80g/m平方纸张）的书帖均应在书帖倒数第三折折缝上破口，以排除书帖内空气而防止皱褶出现，但现在有许多单位在手工折页时，明知应破口，但一味追求产量就是不破口，最后书籍装订后皱褶极为严重而无法补救。

The sensitivity studies of break location show that the cold leg SBLOCA is more serious.

试验回路的破口位置敏感性分析表明：在破口尺寸相同的情况下，冷端破口失水事故的事故后果更严重一些。

Finally, the paper ties up engineering practice. AC600 design based accidents such as double ends cool leg lost of coolant accident, double ends hot leg lost of coolant accident and main steam line break accident have been analyzed in the paper.

最后，本文密切结合工程实际，用开发的PCCSAC-3D程序对先进压水堆AC600的设计基准事故进行了计算分析，并对剧烈喷放的破口附近提出了破口喷放缓冲区模型，破口喷放出的流体在缓冲区内迅速得到均匀混合。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
