Structural matter drops to hit water with fixed rate phut from certain height, inchoate and main the structure that attacks water process in the light of phut is answered begin research, and press mutation of field of force and Xing Bo to wait to study however to entering the underwater after water less, and add with each passing day as large bridge and marine project much, the construction in these projects and the phenomenon that phut of large construction content also appeared to hit water in use process, like Guangdong 9 rivers big bridge is bumped to break down after collapsing, large area bridge floor falls into surface to wait, the meeting such as mutation of field of pressure of the underwater after this kind of phut hits water and Xing Bo is right all round structural products gives birth to certain influence, evaluate this kind of influence to have real project sense to construction and design.

结构物从一定高度落下以一定速度砰击水面，早期主要针对砰击入水过程的结构响应开展探究，而对入水后水下压力场突变和兴波等却探究较少，而随着大型桥梁和海洋工程日渐增多，在这些工程的施工和使用过程中也出现了大型结构物砰击入水的现象，如广东九江大桥被撞垮塌后大面积桥面落入水面等，这种砰击入水后水下压力场突变和兴波等会对四周结构物产生一定影响，评价这种影响对施工和设计具有现实的工程意义。

When the relative soil water content were 55%-40%, the main reasons of the photosynthetic rate declined were stomatic limitation. When the relative soil water content were 20%, the main reasons of the photosynthetic rate declined were nonstomatic limitation.

干旱胁迫下，光合速率的下降是气孔因素与非气孔因素双重作用的结果：轻度干旱胁迫下（土壤相对含水量55%~40%）气孔限制是光合速率下降的主要原因，而严重干旱胁迫下（土壤相对含水量20%）非气孔限制是光合速率下降的主要原因。

The land use pattern had changed by a relatively large margin in Neijiang city from 1997 to 2005. The main tendency of this change is that with remarkable reduction of cultivated land that decreased by 9936.11hm~2, unutilized land and water area, while garden land, forest land that increased by 7032.23 hm~2, grass land and building land increased notably. And during the research time, the speed of land use type change reduced from garden land, traffic land, forest land, residential areas and industrial and minings land, cultivated land, unutilized land to water area. The main trend of general dynamic degree changed from progressive increase to degression. From the analyses of land use diversion matrix, we know resulting in the quantity change of land use was that cultivated land being occupied by construction,adjustment in structure of agriculture and the implementation of the national reforesting formerly cultivated land policy in Neijiang city.

结果表明：1997～2005年间，土地利用类型发生较大幅度变化，总体上呈现耕地、未利用地、水域面积显著减小和园地、林地、牧草地、建设用地面积增大的趋势，其中耕地面积减幅最大，达9936.11hm~2，林地增幅最大，达7032.23 hm~2；土地利用类型变化速度依次为园地＞交通用地＞林地＞耕地＞居民点及工矿用地＞未利用地＞水域，其中园地为2.67％，水域为-0.01％，综合土地利用动态度呈现先递增后递减的趋势；从土地利用类型转移矩阵分析得出，建设用地占用耕地、农业结构内部调整、&退耕还林&是导致内江市土地利用类型数量变化的重要原因。

Result showed that, with the controlled facility, the water storage is about 19×10^3 m^3/km of in the main drainage canal, the groundwater table in farmland is raise about 0.3 to 0.5 m and the crop water use is increased about 50 to 80 mm comparing with the non controlled main drainage canal.

结果表明，单位长度大沟年调蓄水量为1.9×10^4立方公尺/km左右，其影响范围内的农田地下水位较无控制大沟平均抬高约0.3~0.5 m，每年可增加作物对地下水的直接利用量50~80 mm，区域年农田水资源调控总量110 mm左右，约占当地年均降雨量的13%；只要控制合理、管理得当，不会因此而影响排水系统对农田涝渍的有效控制或降低原有排水工程的除涝降渍标准。

Geomancers clever often from the main level of the mountain, which Hill, Dachaoshan the distance, blue dragon, white tiger encircled mountain conditions, such as water, good or bad times to determine the location of graves and tombs of the building echoes the main high mountains such as the is higher with a large tombstone, if the Blue Dragon, White Tiger Hill to be a defect of the hand, against the current, and the case of urgent Hill, the altar should be thick and tall, hand should be straight, external expansion; if the water, then the altar should be low thin, care should be surrounded by hand, which arch and build the mountain Road to alleviate the pool and so on.

高明的风水师往往从主山的高低、案山、朝山的远近、青龙、白虎山的合围状况、水的顺逆等情况来确定墓穴的位置，并于墓的建筑相呼应，如主山高的则配较高大的墓碑，若青龙、白虎山有缺损的加以护手，逆水的、案山紧迫的，祭坛应厚且高耸，护手应挺直、外扩；若是去水的，则祭坛应低薄，护手应环抱、内拱，并筑起道池以缓解山势等等。当然所有的建筑必须符合相关尺寸，才能使墓穴的建筑与山川形势匹配，与大自然融为一体，才能天人合一，福泽子孙。
