Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.

研究结果显示，两孔记录的古气候波动可与深海氧同位素曲线进行对比：对应于深海氧同位素曲线第6阶段(MIS6)，堆积厚层的河道相粗颗粒沉积及第3硬土层，反映当时气候寒冷；第5阶段(MIS5)，为滨海湖沼沉积，沉积物的颗粒显著变细；第4阶段(MIS4)，本区形成第2硬土层；第3阶段(MIS3)的早期，本区也发育滨海湖沼沉积，中晚期则形成潟湖—砂坝体系，在滨海平原区普遍发育粉、细砂层；第2阶段(MIS2)，地层由下粗上细的沉积序列构成，下部为黄灰、棕黄色粉砂，上部则为棕黄色或暗绿色硬粘土。

Construction in China is often slapdash, with builders usually claiming to be able to throw up a two-storey school in less than two months, but in Sichuan there was a suspicion of deliberate negligence.

在中国，部分建筑是草率建成的，建筑商经常声称能在不到两个月内速建一栋两层学校，而在四川，此前在这一方面有蓄意疏忽的嫌疑。

And by the help of further reasoning, which if drawn out would have been exhibited in two or three other syllogism, you arrive at your final determination, I will not have that apple.

更深一层的理论如果被引出，就会出现在其他的两个或三个逻辑论中。在这种更深一层的理论的帮助下，你会实现你最终的目标，我将得不到那个苹果。

Two-ply refers to materials that twist two threads together into a single thread, thus increasing the fabric's thread count and creating a stronger thread.

两层材料，是指两个线程一起扭成一个单一线程，从而增加了织物的线程数和创造一个更强有力的线程。

October 1987 are completed within a base,"Guangdong Stadium," the entire museum covers an area of 12,200 square meters, the venue of 1,700 square meters, high-quality wood floors, at a time Points-electric installations, air-conditioned, sound And lighting equipment, the gallery can accommodate 2,800 people. December 1989 in the west side stadium built Wang Qiuguan, two-story building, home to bottom, is the area of 1680 square meters of multi-purpose game room, north and south on both sides have a standard tennis driving range; upper has two regular venues North and South on both sides of a 400-seat spectator stands, the things I observed on both sides of the corridor and television filming.

1987年10月基地内建成"广东体育馆"，全馆占地面积1.22万平方米，比赛场地面积1700平方米，优质木板地面，场内设有多功能电动计时记分装置，装有空调、音响和灯光设备，观众席可容纳2800人。1989年12月在体育馆西侧建成网球馆，两层建筑，底层为主场，是面积1680平方米的多功能比赛大厅，南北两边各有1个标准网球练习场；上层建有两个正规比赛场地，南北两侧有400座位的观众看台，东西两侧为观察席及电视拍摄走廊。

The 〓～t curve of UF with periodic back flush can be divided into two sections: the initial section represents the accumulation stage of undetachable cake layer, and the final section represents the equilibrium stage of accumulation and detachment of cake layer.

对周期反冲洗膜污染过程分析结果表明，周期反冲洗超滤〓～t曲线可分为两段：起初的直线增长段为不可逆滤饼层的累积阶段，直线的斜率为各次反冲洗不可逆膜阻增量△R；后期的水平段为滤饼层累积与剥离达到平衡的阶段。

By formulating the apparent porosity cross calibration model of these two logs, and adopting the same matrix logging pa rameters as those of the practical complex lithology, the study constructs new log curves, utilizes and amplifies the different responses of neutron and density logs, eliminates multiple solutions caused by inaccurate calibration lithology, makes the overlayed curves take the same units, greatly improves the gas-i dentification resolution of this combination, intensifies the visual effect of gas indication.

从而能够放大中子、密度测井对地层中天然气的不同响应，消除刻度岩性不准确产生的多解性，统一重叠曲线的量纲，大大提高这两种测井组合识别气层的分辨率，增强气层指示的直观性。

One of their crucial functions is to make up the error recovery due to the deteriorative channel transmission conditions, provide better links condition to the transmission control protocol of upper layer. Then, the study of RLC and MAC two layers retransmission mechanism is very important to whole wireless system.

这两层有一个重要的作用就是弥补无线通信系统中信道条件不理想或底层不理想造成的传输错误，为上层的传输协议提供性能良好的链路环境，提高上层数据业务在无线传输通信系统中的性能，因此研究RLC和MAC层的重传性能对整个无线传输系统是很重要的。

A new sucker-rod pumping system of double-layer separate recovery is developed in order to solve the interbedded disturb problem of multilayer heterosphere oil-field radically. The present fault diagnosis technique can't well suit to diagnose the pumping system. So far, the public reports in the field are few at home and overseas.

为从根本上解决多层系、非均质构造油田的层间干扰问题而研制的两层分采同步抽油系统是一种新型的采油设备，现有的采油系统领域的故障诊断技术难以满足对该系统进行故障诊断的需要，国内外也没有这方面的研究报导。

Adopts the all- air and natural ventilation system for the opening north wall;the floating floor and isolation table to isolate machine vibration,the sounds insulation materials between two walls to insulate noises in the plant;the air conditioning system separately for the audience area and sports area,the fan-coil unit and floor heating system only for the sports area to adapt the use after the Olympic Games,the natural ventil...

针对1层两个比赛厅北墙敞开的特点，采用全空气空调系统、排风从敞开空间自然排出方案；针对空调机房距4个比赛厅仅一墙或一板之隔的特点，空调机隔振采用浮筑楼板加减振台板、隔声采用双墙中间夹隔声材料层的方案；针对奥运会后观众区改作他用、运动区继续作集训使用的特点，观众区和运动区各有一套空调系统，运动区另设风机盘管和地板供暖；针对步枪、手枪射击时产生弹药味的特点，采用吊顶设通风格栅、高窗设电动开启的自然通风方案。
