半关闭

Still, local people habitually leave the engines running if they have to stop off for half an hour, and some leave them on all day while at work to stop them conking out and to make driving bearably warm.

本地人一样习惯在离开汽车半个小时的情况下不关闭引擎，有人甚至在上班时整天让引擎开着，以防汽车冻坏，也可以使车里暖和一点。

The subject walks into this phone booth-like device, and translucent bifold doors close around him.

主题走进这个电话亭般的装置，和半透明bifold门关闭在他的周围。

Then, correct tightening is completed by turning the nut a half or 3/4 turn.

那么，正确的紧缩完成转动螺母半或3月4日关闭。

At my coming, he slowly slipped a glance of his agate eyes at me from between his half-opened lids, which he closed again almost at once, thinking to himself,"It is nothing; it is only my friend."

在我来了，他慢慢地滑落在我对他的玛瑙眼睛一瞥之间，他从半开的盖子，他几乎再次关闭，对自己的思想，&这没什么，它只是我的朋友。&

At the same time, the government announced it would be closing thousands of workplace lunchrooms, in exchange for paying employees a daily stipend, and that the food ration, in existence for nearly 50 years, supplying rice, beans, sugar, salt and other basics at subsidised prices, must eventually go.

同时，古巴政府宣布，将关闭成千上万个职工食堂，改为按日向员工发放补贴，并宣布，存在近半个世纪之久的食品配给制最终必须取消，该制度以补贴价格供应大米、豆、糖、盐以及其它基本物品。

With a view to knowing more about how NaHSO〓 increased Pn in higher plants, we studied the effects of NaHSO〓 on the cyclic electron flow around PSI in wheat (Jing 411) and rice (Shan-you 63). It was observed that the transient increase in chlorophyll fluorescence after the termination of actinic light was increased and the half-time of re-reduction of P700〓 was shortened in both rice and wheat leaves, indicating that cyclic electron flow around PSI was accelerated by NaHSO〓 treatment.

为探究NaHSO〓促进高等植物光合作用的机理，我们研究了NaHSO〓对小麦（京411）和水稻（汕优63）围绕PSI的循环电子传递影响，实验发现低浓度NaHSO〓可促进小麦和水稻叶片的叶绿素荧光在作用光关闭后的短时上升以及缩短叶片在远红光后P700〓再还原的半时间，表明NaHSO〓可以促进小麦和水稻的围绕PSI的循环电子传递。

In accord with the promotion in the photosynthetic oxygen evolution and ATP content, the transient increase in chlorophyll fluorescence after the termination of actinic light was increased; and meanwhile, the half-time of re-reduction of P700〓 in the presence of DCMU after a pulse light under background far-red light was shortened by approximately 30%, indicating that cyclic electron flow around PS1 was accelerated by the treatment.

与此同时，我们还发现经NaHSO〓处理后，蓝藻细胞的作用光关闭后叶绿素荧光瞬时上升的幅度增加，同时在远红光背景下和DCMU存在时，饱和闪光后蓝藻细胞P700〓再还原的半时间缩短约30％，表明低浓度NaHSO〓溶液处理能够促进蓝藻细胞围绕PSI的循环电子传递。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
