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。

In order to overcome this problem, in this paper, the surface electric current of the conducting sea surface and the first-order scattering from the conducting plate are obtained by employing Physic Optics method. The backscattering field of the time-dependant sea surface is calculated by using Kirchhoff Approximation. Meanwhile, taking the advantage of a newly developed technique that utilizes the reciprocity theorem, the difficulty in formulating the secondary scattered fields from the composite target is reduced. The dependences of the backscattered field on the parameters, such as the wind speed and the sizes of the plate are discussed.

使用有限元方法对成藏期三维应力场数值模拟研究的结果表明，北西方向断层受挤压强烈，断面正应力大、断层泥相对发育，易于封堵；北东方向断层封堵性差，常成为油气由西北往南东运移的"有限性"通道。

And the results indicate that the principal stress directions in study area are mainly NE-SW, and the second substage tectonic twist made the direction deflect from North to East, but the primary direction changed little; tectonic activities during the O〓～S～D stage is some violent, most of the area are under high stresses status, and rock fracture degree is correspondingly higher, as coinciding with the drill cores observation, i.

通过数值分析，模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场，结果表明：研究区主应力方向为北东～南西向，第二期的构造扭动使其由北向东发生了一定的偏转，但总的方位变化不大；O〓～S～D时期，塔中地区构造运动较强，研究区大部分处于高应力状态，岩石破裂程度较高，而岩芯观察结果也证实了这一结果，即O〓灰岩地层中早期形成的构造结构面比较发育，单个结构面的规模也较大；C～P时期，岩石的破坏程度较早期有所提高，主要表现在两个方面，一是各局部区岩石的破坏程度普遍有所提高；二是各个级别破裂区的分布范围相应地扩大了；研究区应力分布表现出明显的不均匀性，特别是剪应力，无论是O〓～S～D时期，还是C～P时期，都有很大的差异性，特别是在小断层的端部，剪应力比较集中，而且在断层的两盘，剪应力方向和大小都变化极快。
