冬季

We suffered the asperity of an antarctic winter.

我们忍受着南极冬季的严寒。

Temperature and humidity: The most comfortable temperature that views and admire pineapple is 15-20 ℃, winter not under 10 ℃, humidity should maintain in in 70-80 ％ above, need often is added to the aspersion in water of the gush on plant or surroundings wet.

温湿度：观赏凤梨的最适温度为15-20℃，冬季不低于10℃，湿度要保持在在70-80％以上，需要经常向植株上喷水或四周环境中洒水增湿。

And it establishes the math model of astatic heat transfer around the digester fermenting. The math model is dispersed by the use of control volume integration. Then, it presents composing of the experiment system and preparing of the experiment devices. It analyses the data of steady operation in summer and in winter. Through analysis, we can know the change condition about the soil temperature around the digester fermenting、the temperature of solution and heat-transfer content.

在实验方面，介绍了实验系统的组成和设备的选取准备，并选取实验中夏季和冬季运行比较稳定的两段时间，进行数据分析处理，通过分析可知沼气池周围土壤温度、料液内温度以及换热器加热量的变化情况，同时，还计算出了钢管换热器的传热系数。

Winter is at an end, for this is the first day of spring.

冬季是结束，因为这是春季的第一天。

S. winter is more expensive than at other times of the year, partly because of shipping costs.

当然，在美国冬季买花比今年其他时间要贵的多，部分原因是运送的费用。

Every winter, millions of fridges hum away continuously and at vast expense, busily maintaining an artificially-colled space inside an artificially-heated house--- while outside, nature provides the desired temperature free of charge.

每年冬季，数以百万计的冰箱，舂坎距离不断在广阔的牺牲，忙着维持一个人工colled空间内一人为炽热的房子---虽然外面，性质，提供了理想的温度，费用全免。

In a city known for its glittering winter Ball Season, couples waltz in the ballroom of Vienna's Auersperg Palace.

在一个城市知名的因为它的闪闪发亮的冬季舞会季节，夫妇们在舞厅跳华尔兹舞在维也纳的Auersperg宫殿。

在这座城市著名的由于它的灿烂的冬季舞会季节，一对对跳华尔兹舞蹈者在维也纳的Auersperg宫殿舞厅。

It is possible that the auroral oval shifts southerly and hence produces this effect in winter .

这可能是由于冬季极光卵向南偏移造成的。

The model is based on two extended heat sources, one is on day side of the auroral oval and the other on night side.

夏季负相扰动发展到较低的纬度，冬季在中纬正相扰动是主要的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
