On the basis of drawing on the technology and experiences of tower assembling and erection for 500kV and 750kV transmission lines in China, such methods suitable to the tower assembling for UHV transmission line as inside suspension pole with outside pulling wires, ground rocker pole and tower crane are adopted and applied in UHVAC test and pilot project, pursuantly the task of tower assembling and erection in this project is completed, from this a lot of practical experiences are achieved and can be available for reference to subsequent engineering and construction..

文章在借鉴我国500 kV和750 kV架空输电线路组塔施工技术和经验的基础上，提出了内悬浮外拉线抱杆组塔、落地摇臂抱杆组塔、塔式起重机组塔等适合于特高压线路铁塔组立的方法。该方法已在特高压交流试验示范工程中得到应用，为后续工程建设提供了技术储备。

On the other hand, when the tropical western Pacific is in a cooling state in spring, convective activities are weakened around the Philippines. In this case, there is an anticyclonic anomaly circulation in the lower troposphere over the South China Sea, and the western Pacific subtropical high shifts westward, thus, the late onset of the SCSM can be caused. Moreover, when the tropical western Pacific is also in a cooling state, convective activities around the Philippines are also weak in summer, since the abrupt northward-shift of the western Pacific subtropical high is not obvious in mid-June and early July and it gradually shifts northward during its northward advance in this case, the East Asian summer monsoon rainband can be maintained in the Yangtze River and the Huaihe River valleys.

相反，当春季热带西太平洋处于冷状态，菲律宾周围对流活动弱，在这种情况下，南海上空对流层下层有反气旋性距平环流，西太平洋副热带高压偏西，从而使得南海夏季风爆发晚；并且，当夏季热带西太平洋也处于冷状态，菲律宾周围对流活动也很弱，在这种情况下，西太平洋副热带高压北进时，在6月中旬或7月初向北突跳并不明显，而是以渐进式向北移动，从而使得东亚季风雨带一直维持在长江流域和淮河流域。

The results show that when the tropical western Pacific is in a warming state in spring, convective activities are intensified around the Philippines. In this case, there is a cyclonic anomaly circulation in the lower troposphere over the South China Sea, and the western Pacific subtropical high shifts eastward, thus, the early onset of the South China Sea summer monsoon can be caused. Moreover, when the tropical western Pacific is also in a warming state, convective activities around the Philippines are also strong in summer, since the western Pacific subtropical high abruptly shifts northward in mid-June and early July during its northward advance in this case, the abrupt northward-shift of the East Asian summer monsoon rainband from South China to the Yangtze River and the Huaihe River valleys is obvious in mid-June and this monsoon rainband again jumps northward from the Yangtze River and the Huaihe River valleys to the Yellow River valley, North China and Northeast China in early July.

分析结果表明：当春季热带西太平洋处于暖状态，菲律宾周围对流活动强，在这种情况下，南海上空对流层下层有气旋性距平环流，西太平洋副热带高压偏东，从而使得南海夏季风爆发早；并且，当夏季热带西太平洋也处于暖状态，菲律宾周围对流活动也很强，在这种情况下，西太平洋副热带高压北进时，在6月中旬和7月初存在明显的突跳，从而使得东亚季风雨带在6月中旬明显由华南北跳到江淮流域，并于7月初由江淮流域北跳到黄河流域、华北和东北地区。

A mass rockslide happened while the pilot shaft of penstock No.2 driving through the wide fracture zone of f 20 fault ,and it was difficult to treat because the rockslide area was in the inclined shaft .

Patients were divided into several groups: the left-to-right shunt type of CHD without pulmonary hypertension , PH secondary to the left-to-right shunt type of CHD, no-shunt existence type of CHD (the three types above were regarded as acyanotic CHD), cyanotic type of CHD, and healthy children as controls. Diagnosis were established by clinical symptoms and signs, chest roentgenography, electrocardiogram, echocardiography, cardiac catheterization and surgery.
