Therefore,tapping potencial of remaining oil to improving oil recovery,the recognition of reservoir intraformational heterogeneity in channel sandbodies is proposed and the main targets of reservoir IOR in channel sandbodies of mature oilfields are pointed out as follows:①shutting off strongly-waterflooded intervals to control ineffective circulation of injected water;②strengthening water washing in medium-waterflooded intervals in order to achieve the aimed waterflood efficiency and even to exceed it;③enhancing injection-production consistency and injector-producer ratio of non-waterflooded or weakly-waterflooded intervals for the propose of realizing effective displacement and imporving conforma nce.

根据我国东部主力油田储层绝大多数都属于河道砂体，注水开发进入高含水阶段后，层内剩余油超过层间剩余油，层内矛盾上升为主要矛盾这一特点，从挖掘层内剩余油潜力出发，提出要重新认识河流砂体储层层内非均质性，并指出高含水期河流砂体储层改善采油目标主要有：①封堵强水洗段，控制注入水无效循环；②加大中水洗段注水冲洗强度，达到目标水驱效率，并有可能超过目标效率；③提高未、弱水洗段的注采对应程度和注采井数比，达到有效驱替，提高波及程度。

According to terrestrial heat professional in China Energy Sources Research Institute: the hot spring water temperature in Tangchi, Lujing County is 63℃ and is the typical hot spring water with sodium sulfide and the total minerals content is 1.2kg/Liter. Compared with "Medical Thermal Mineral Water Quality Standard "(refer to natioanl standard GB11615-89 ), the spring water in Tangchi belongs to the fluorin water and the silicion water of the thermal mineral water. It contains metaboric acid,lithium,sulfureted hydrogen etc. and has great effect on many diseases such as arthopathy, cardiovascular disease, digestive system diseases, skin diseases, and neuritis, respiratory infections, etc.

中国能源研究会地热专业文员会评价：庐江县汤池温泉水63℃，属于硫酸钠型水，是典型的温泉水质类型，其所含矿物质总量高达每升1.2克；对照《医疗热矿水水质标准》（见国标GB11615-89），汤池温泉属于医疗热矿水的氟水和硅水，并且其中所含的偏硼酸、锂和硫化氢等成分具有综合疗效，这种类型的医疗热矿水对骨关节病、心脏血管病、消化系统病、皮肤病、神经系统病和呼吸系统病等数十种病症，均能具有显著或有效的疗效。

The method of fuzzy partitional cluster algorithm is applied to classify the multi-target in the air combat,to be aimed at the shortcoming of traditional algorithm in calculating attack strategy difficultly.This algorithm reduces the computational complexity,and raises the operating speed by considering multi-target as a whole.

针对传统多机多目标攻击不易解算攻击任务分配，且计算量大的问题，提出基于划分的多目标模糊聚类算法，该算法根据目标属性的相似性进行多目标分类，可以有效地降低多目标任务分配解算维数，减少运算量，提高解算速度。

The geometry of canopy and interception of photosynthetically active radiation were measured.

通过实测和理论计算，结果表明：高原地区冬小麦叶片比平原地区的更趋于直立，具有比平原地区低的消光系数，能够容纳较大的绿叶面积和有效穗数；当冠层对PAR的截获率趋于饱和时，高原地区麦田可容纳的最大绿叶面积可达8.6，是平原地区的1.4倍左右；开花到成熟期间的叶日积大约可达平原地区的2倍，绿叶面积持续时间长；整个生长季期间，高原地区的PAR总量是平原地区的1.7倍，单位绿叶面积所截获的PAR是平原地区的1.3倍，又由于其叶片的趋于直立，故从上到下叶片受光比平原地区更均匀和充分，群体光合潜力高，对PAR的利用率更高。
