Verified by the test to the samplings from a depth of 153m at No. 1125 boring well, the age of the subsurface layer at Du-Cun, Suznou, Jiangsu Province is around 800.000 years old, The granutarity parameter and the pattern of its progressive change illustrate that the sediment is mostly fluviolacustrine facies. An analysis of the mineral and sporo-Pollen compositions indicates 8 stages of environmental evolution, 3 of which comparatively colder.

The Okinawa Trough, a narrow sediment basin, is situated in the middle part of the northern West Pacific Ocean. Sample site Z14-6 is located in the middle of the Okinawa Trough (27°07'N, 127°27'E, water depth 739m). Faunal trends and statistical and FP-12E transfer function analysis indicate that there were three warm periods during the last 120 000 years, and two cold periods in the last interglacial. Oxygen isotope substage 5e was the warmest periods, during which the winter sea surface temperature (SSTw) was 1.9℃ higher than that of today; Oxygen isotope stage 2 was the coldest period, during which the SSTw reached 12.4℃ and summer sea surface temperature (SSTs) was below 25.9℃, which were 6.8℃, 2.3℃ lower than that of present respectively. The difference, between SSTw and SSTs is related to the degree of frigidness. The Paleo-Kuroshio Current speed was controlled by global climate. The current velocity increased and the current area extended during the warm periods, and conversely in the cold periods. The current quantity fluctuation of Paleo-Kuroshio caused the changes of sea surface temperature.

冲绳海槽Z_(14-6)孔柱状样于1981年取得,该孔浮游有孔虫系统鉴定、统计及转换函数分析表明,该区12万年来曾存在三个温暖时期,末次间冰期存在两次寒冷波动。氧同位素5e亚期为最温暖时期,海水冬季表层水温高出现代1.9℃;氧同位素第2期为本区晚更新世以来最寒冷时期,冬季海水表层水温降至12.4℃,比现今低6.8℃。海水冬、夏表层水温差异与气候的寒冷程度有关,气候越寒冷,温差越大。此外,本文还就黑潮的某些古海洋学特性进行了初步探讨。

A pig house proper for pig farming in cold agricultural area was designed.Ac- cording to the habits of pigs,i.c.sleeping,feeding and extracting at different places, and chosing optimal thermal environment to sleep,the semi-open house was divided into two parts by a walt:sleeping area and exercising area.In the wall between the two areas,there was a door way,which was (?)ed by a d(?)r cu(?)tain or a free door during cold winter.The size of upper port of door way can be regulated for vantilati- onfor sleeping room,so that the micro-climate of the room can be controlled.Thermal insulation of the surro(?)mding structure of the room was improoed and the thermal resistant coefficients of roof and wall were 2.5 and 1.6m h℃ K(?)al~(-1) respectively. In the wall opposite to the passing route,there was an emergency window which is open during hot summer,whereas during winter,the exerciring area was covered by vinyl sheet with a ventilation window.so that it moderated the cold air before ente- ring the sleeping room.By this way,a pig house with double micro-climate in sleepi- ng and excersing area was built up. One unite of the house,with availab(?)e area of 6m~(?),can provide enough room for farrowing sow or 10 growing-finishing pigs.Therefore,according to the extent of the pig farm,the unites of the house can be decided.The house designed is suitable to middle or small farms and family farms in cold region. Operative experiments showed that in January the average temperature in the sleeping room was 8.9℃ whe h theventilation rate was controlled at no less than 8m~3/h for a pig with 50kg body weight.

依据猪趴卧、采食、排便占据舍内不同区域和寻求温热最舒适位置趴卧的生物习性,半敝开式猪舍分作趴卧区和运动场两部分。本设计是在窝与运动场间设墙隔开,只留出入门洞,寒冷时期用门帘或活动门把门洞封闭起来,可以调节的换气孔,使趴卧窝内形成通过调节换气量可以控制温热状态的小气候。加强了趴卧窝围护结构的隔热性能,顶盖和墙体最低热阻值分别为2.5和1∶6m~2·h·℃·KCol-(?)。在门洞对侧墙上设防暑应急窗,越冬时在运动场上方扣覆塑料棚,棚上开设换气孔,使棚内成为趴卧窝的缓冲区。这就形成了窝内和棚内双重小气候的猪舍结构。每单元窝内净面积6m~2,养1头母猪或10头肥猪。随饲养规模而增减单元数量。本设计适合寒冷地区中小养猪场或专业户使用。
