505他并不想根据长子继承制、男子平分继承制或末子继承制，把那幢有着门房和马车道的男爵宅邪及其周围那一大片辽阔的英亩、路得和平方杆法定土地面积单位，（估价为四十二英镑的泥炭质牧场地，或者那座被描述为&都会中的田园&或&健康庄&的有阳台的房子或一侧与邻屋相接的别墅，继承下来并永久占有。他只巴望根据私人合同购买一所继承人身分不受限制的不动产：要坐北朝南的一座草屋顶、有凉台的双层住宅，房顶上装起风向标以及与地面相接的避雷针，门廊上要爬满寄生植物，橄榄绿色的正门最后一道工序漆得漂漂亮亮，赛得过马车。门上有着精巧的黄铜装饰。房屋正面是灰泥墁的，屋檐和山墙涂着金色网眼花纹。尽可能让房子耸立在坡度不大的高台上，从那圈着石柱栏杆的阳台上，隔着现在空着、将来也不得占用的牧场地，可以聎望四周的一片好景致。单是自己的庭园，就有五、六英亩之谱。它与最近的公路的距离适度：夜晚从修剪得整整齐齐的鹅耳枥树篱上端和缝隙间，可以瞥见室内的灯光，从首都边界的任何地点丈量，与这所房子相距至少也有法定一英里。不出十五分钟就可以轰电车或火车铁道沿线。（例如往南去登德鲁姆或往北去萨顿，就像是南北两极。经过验证，据说这两处气候都适合肺结核患者。）凭着继承人身分不受限制的不动产转让证拥有房屋和地基，租借期限为九百九十九年。宅邸里包括一间有着凸窗的客厅，一间起居室，四间卧室，两间仆役室。砌了瓷砖的厨房里还安装了多用途的铁灶和洗涤台，休息厅里备有放亚麻布床单衬衫用的壁橱，分成几层的氨熏橡木书柜，放着《大英百科全书》和《新世纪辞典），横陈着一把把中世纪或东洋的古老刀剑；还有通知开饭的锣，雪花石膏做的灯，悬垂着的饰钵，附有电话号码簿的胶木自动电话听筒；手织的阿克斯明斯特地毯，是奶油色质地，周围镶着棋盘图案。有着兽爪形柱脚的牌桌。壁炉装着大型黄铜格栅，炉台上摆着精密的镀金计时表，准确无误地发出大教堂那样的钟声，附有湿度计的晴雨表，蒙着鲜红色长毛绒面子、装着上等弹簧、中心部位富于弹性的舒适的长靠椅和放在角落里的备用椅，日本式三扇屏风，痰盂（俱乐部里摆的那种，用深紫红色皮革制成，只要用亚麻子油和醋一擦，不费吹灰之力就能发出光泽，焕然一新。）室中央悬挂一盏金字塔式枝形吊灯，射出灿烂的光辉。一截弯木上栖着一只驯顺得能停在手指上的鹦鹉，墙上糊着每打价为十先令的压花壁纸，印着胭脂红色垂花横纹图案，顶端是带状装饰；一连三段栎木楼梯，接连两次拐成直角，都用清漆涂出清晰的木纹，梯级、登板、起柱、栏杆和扶手，一律用护板来加固并涂上含樟脑的蜡；浴室里有冷热水管，盆汤、淋浴，设备俱全。位于平台上的厕所里，长方形窗子上嵌着一块毛玻璃，带盖的坐式抽水马桶，壁灯，黄铜拉链和把手，两侧各放着凭肘几和脚凳，门内侧还挂有艺术气息浓厚的油画式石版画。另外还有一间普通的厕所；厨师、打杂的女仆和兼做些细活的女佣的下房里也分别装有保健卫生设备（仆役的工钱每两年递增两英镑，并根据一般忠诚勤劳保险，每年年底发奖金一英镑，对工龄满三十年者，按照六十五岁退职的规定，发退职金）；餐具室、配膳室、食品库、冷藏库、主楼外的厨房及贮藏室等、堆煤柴用的地窨子里还有个葡萄酒窖（不起泡、亮光闪闪的葡萄酒），这是为宴请贵宾吃正餐时预备的。对整座楼房都供应一氧化碳瓦斯。

Based on the review of the description of subtropical high and the research on its formation, fluctuation characteristics and physical mechanisms, it is found that the subtropical high is refered to the area where pressure is relatively larger. Its formation is due to the existence of mean meridional circulation that accumulates air mass to subtropical areas. The subtropical high is belt-like with meridionally non-uniform feature and this is a zonal mean point of view.

通过对副高的描述、形成及演变特征和物理机理的研究进行回顾，认为：副高是相对的气压的高值，是由于平均经圈环流的存在，使得有空气质量在副热带地区的堆积而形成的，成为带状，表现出在经度方向的不均匀，这是一种纬向平均的观点；同时，在这个平均的高压带上常常有闭合的单体存在，表现出纬向的不均匀。

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈&肥皂盒&形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.

进一步采用以第4层次基准面旋回中相当最大湖泛面的相转换面和具有区域性暴露侵蚀作用的层序边界面为等时地层对比框架的边界，对发育于MSC2—MSC4三个第4层次基准面旋回的第3层次基准面旋回内砂体进行了逐层等时对比，探讨第4层次等时地层对比格架内储集砂体发育分布规律，及储集砂体的非均质性特点，研究发现：①第4层次基准面上升初期发育的水下分流河道，砂体呈连续叠置、侧向迁移受限，纵向上呈长距离延伸的带状产出，砂体间泥、粉砂岩夹层少，储层非均质性相对较弱；②在第4层次基准面上升中期发育的水下分流河道侧向迁移活跃，纵向延伸过程中分流汇合作用强烈，以形成网状或席状连片砂体为主，但砂体间泥、粉砂岩夹层逐渐增多，储层非均质性增强；③第4层次基准面上升晚期和下降早期，不利于储集砂体发育，仅出现少量薄的水下分流河道、水下决口扇、远—河口砂坝砂体。
