Objective To investigate the skill,efficacy and safety of laparoscopic sacrospinous ligament fixation,the LSSLF technique was used as part of the vaginal repair procedure for marked uterovaginal prolapse, and in the treatment of vault prolapse.

目的 探讨腹腔镜下骶棘韧带固定术（laparoscopic sacrospinous ligament fixation LSSLF）治疗子宫脱垂和阴道穹隆脱垂的手术技巧和临床疗效。

The calculation results of some examples are given. In the unstratified case, the cake cross section at any point is circular. When the flow is stratified, buoyancy cause the wake, which initially grows at the same rate in all directions, to collapse in the vertical direction and flatten out horizontally producing a very wide and thin rectangular shape.

在稳定层化海洋中，潜艇尾流以圆锥形增长；在非层化海洋中，初期尾流也以圆锥形增长，但在浮力作用下，尾流垂向增长崩溃，然后以又薄又宽的近于矩形截面增长，最后垂向尺度趋于常值。

In the two test sites, the soil water movement numerical models of vertical-one-dimension and cross section two-dimension have been established with the softwarer Vadose/W and self-programming code, of which the advantage is that it can deals with lower boundary and the upper boundary (such as meteorologic, vegetational, etc) conditions in convenience. The fitting between the model and observation data from sites indicates that the models are relatively high precision. So the models can be used to study problems such as soil evaporation, infiltration to recharge groundwater and so on under various conditions.

The reservoir rock types in the region of interest are grain limestone, algal limestone, cryptite, siltstone, muddy limestone and mudstone. The thesis identified as a result of changes in the deposition causing the heterogeneity in plane, and then the geological oil reserves have been calculated in accordance with the areal heterogeneity.3、Based on the data of core analysis, bore logging, array induction imaging log and FMI, porosity and permeability model were built using regression analysis. Through testing 45 rock samples, a, b, m, n value were obtained and used to calculate single-layer oil saturation value using the Archie formula. According to the theory of laterolog and inductolog, resistivity ratio and cross plot were used to identification effective thickness. Effective thickness was identified delicately in 103 wells. Based on the over work, active porosity and oil saturation was calculated accurately.4、According to observation of 100 pieces of the thin slices, cast thin slices and 383m core in three wells, the chief diagenesis in this area were compaction, cementation, denudation and cataclasis. Cementation and denudation were universally influenced active porosity this area. The intergranular pores, residual pores and secondary pores were formed in thin carbonated reservoir of lacustrine facies.5、The influence of reservoir heterogeneity to reservoir calculation was analyzed systematically using actual data. And the conclusions were as follows:①The principal reason leading to oil distribution unequal is interior structural feature of reservoir in structural hydrocarbon reservoir.

迎浪航行是船舶航行时经常选取的航态，在这种航态下影响船舶作业的主要因素是船的纵摇，垂荡，垂向加速度，甲板上浪及砰击等，且这些方面难以通过减摇措施得到改善，因此这些要素是评价船舶运动性能的重要条件。

But our Patron warn'd by this Disaster, resolved to take more Care of himself for the future; and having lying by him the Long-boat of our English Ship we had taken, he resolved he would not go a fishing any more without a Compass and some Provision; so he ordered the Carpenter of his Ship, who also was an English Slave, to build a little State-room or Cabin in the middle of the Long Boat, like that of a Barge, with a Place to stand behind it to steer and hale home the Main-sheet; and Room before for a hand or two to stand and work the Sails; she sail'd with that we call a Shoulder of Mutton Sail; and the Boom gib'd over the Top of the Cabbin, which lay very snug and low, and had in it Room for him to lye, with a Slave or two, and a Table to eat on, with some small Lockers to put in some Bottles of such Liquor as he thought fit to drink in; particularly his Bread, Rice and Coffee.

这次意外事件给了我们主人一个警告，他决定以后得小心谨慎一些，出海捕鱼时带上指南针和一些食品。正好在他俘获的我们那艘英国船上，有一只长舢舨。他就下令他船上的木匠--也是他的一个英国人奴隶--在长舢舨中间做一个小舱，像驳船上的小舱那样；舱后留了些空间，可以容一个人站在那里掌舵和拉下帆索；舱前也有一块地方，可容一两个人站在那里升帆或降帆。这长舢舨上所使用的帆叫三角帆，帆杆横垂在舱顶上。船舱做得很矮，但非常舒适，可容得下他和一两个奴隶在里面睡觉，还可摆下一张桌子吃饭；桌子里做了一些抽屉，里面放上几其他爱喝的酒，以及他的面包、大米和咖啡之类的食物和饮料。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
