But sober see, these achievements were made in the case of decreased rainfall for two consecutive years, we realize that environmental protection work still faced many problems in our County. Mainly in the PM2.5 and PM10 air quality monitoring indicators often exceeding, dredging of river section's water quality is not stable, and rural non-point source pollution has not been radical, Wade through the corporate environmental risk, livestock pollution rebound from severe, a wealth of protection and use of water resources is not well. If this year's rainfall, these problems will be exposed, and raw materials caused a great deal of pressure to go green. To solve these problems, we focused on three aspects of the work of environmental protection: (a) in accordance with the ... ... Real good green.

MU. 第二次弯矩分配，然后不再传递。实际上，弯矩二次分配法，只将不平衡弯矩分配两次，将分配弯矩传递一次。 图5 弯矩分配与传递 (6)作弯矩图 将杆端弯矩按比例画在杆件受拉一侧。对于无荷载直接作用的杆件(如柱)，将杆端弯矩连以直线，即为该杆的弯矩图;对于有荷载直接作用的杆件(如梁)，以杆端弯矩的连线为基线，叠加相应简支梁的弯矩图，即为该杆件的弯矩图。例如顶层边跨横梁B的跨中弯矩为 ，510 Million.
