The DNA was extracted from mature Spinacia oleracea L.separately by the method of CTAB, then used as template after mixed by gender to be amplified with the optimized RAPD reaction condition. A total of 160 primers (10 bp) and 40 pairs of primers were screened, 44 primers of which produced clear patterns.

菠菜为雌雄异株植物，用CTAB法提取其雌雄成株幼嫩叶片总DNA分别构建雌、雄株的DNA池，以之为模板，用已优化的RAPD体系扩增，在160条随机引物(10 bp)和40个引物对中筛选出44个扩增效果较好的单引物，再从中进行进一步筛选。

On the basis of that,the authors of this paper consider that it is better to determine the instability of seismic source process by use of the syzygial tide than by use of the semi-diurnal tide only;the method can avoid many complex problems of seismic sources without affecting the efficacy of earthquake prediction.

由此作者认为用朔望潮比单纯用半日潮来判断震源过程的不稳定性更好，它可以回避震源地方的很多复杂问题而不影响预报地震的效能。

In this paper, the improvement of synthetic method of 2-acetylaminotropone is introduced. 3-Acetyltropolone reacted with low concen-tration methylamine solution and solvent was directly evaporated in reduce pres-sure to give 2-acetyl-7 -methylaminotropone in good yield. The compound reacted with phenyltrimethylammonium tribromide to give two new compounds.

本文介绍2-乙酰基-7-甲胺基酮合成方法的改进——用挥发性小的低浓度甲胺溶液与3-乙酰基酚酮反应；和采用直接减压蒸除溶剂法分离产品，得到较好产率的2-乙酰基-7-甲胺基酮；用化合物与三溴化苯基三甲铵反应，得到两种至今未见文献报道的新化合物。

Use properly placed, properly made matched HUNTING arrows (matched to the bow/archer combination, and made for hunting; hunting arrows should be about 10 grains for every pound of draw, sometimes heavier - 400 grains for a 40 lb bow is a good starting point), with SHARP broadheads, and you won't have to worry about being "underbowed"-- as long as you pay to the local regulations where you hunt.

只要能准确的打中有效部位，用猎箭（每磅至少10格令，对初学者来说40磅的配400格令挺好的），用极锋利的猎箭头，你不用担心威力不足--参照各州法律规定在什么地方狩猎（译者说明，一般必须上树）。

The artifical fillers are hung under the plant floating bed then the remedial system combined by plant and microorganism came into being. The remedial effectiveness of the system was visibly better than that of the phytoremediation alone. So when the temperature is higher the remedial system combined by plant and microorganism is the preferable remedial technique to remedy contaminated water. In autumnal end and winterly outset, the temperature is lower, the plants begin to fade and die, and the plant must be harvested lest the relict of plant should contaminate water again. At the same time the technique combined by immobilized nitrogen cycling bacteria and microorganism which already existed in the water was used to remedy contaminated water.

将人工填料悬挂于植物浮床下，形成植物和微生物相结合的修复系统，其修复效果明显好于单独植物修复技术，因此温度较高时用植物和微生物共同结合的生物修复技术修复水体污染；秋末冬初温度较低时，植物开始死亡，必须将植物收割，以免植物残体造成二次污染，此时用固定化氮循环细菌和水体中原有微生物相结合的技术来修复水体的污染。

He said the witches was pestering him awful these nights, and making him see all kinds of strange things, and hear all kinds of strange words and noises, and he didn't believe he was ever witched so long before in his life.

这个黑奴的脸看上去是一副脾气好、傻呼呼的样子。他的一头卷发用细绳子扎成一撮一撮的。那是为了避开妖魔作祟。他说，这些天晚上妖魔作祟，害得他好苦。

Tests on road performance of SMA mixture with terylene long fiber and xylon fiber were conducted at both high temperature and low temperature. It was found that the resistances of lignin fiber to asphalt run-off, deflection at high temperature, and water damage were higher than those of terylene long fiber, while the effects of lignin fiber and terylene long fiber on anti-dispersion loss performance and anti-cracking performance at low temperature were basically similar.

通过沥青混合料路用性能试验，研究了涤纶长纤维与木质素纤维对SMA混合料高、低温等路用性质影响，发现同等掺量情况下，木质素纤维对SMA混合料抗析漏性能、抗高温变形性能和抗水损害的贡献好于涤纶长纤维；而二者对混合料的抗飞散损失性能和低温抗裂性能的影响基本相同。

The filtration produced by our factory has such good performance as high temperature resistance, flame resistance, good chemical stability, excellent firmness strength, low chlorin evolution, metal melting erosion resistance, good quality of filtering sand and convenient use, which is widely used for foundry filtering netlike cloth , filtering treatment for metal melting and improving casting quality, in addition , for such industrial fields as filtering for chemical erosion liquid , tobacco leaf filtering net for environmental protection, and fire fighting.

本厂生产的铸造过滤网具有耐高温、耐烧蚀、化学稳定性好；良好的刚强度、发气量低、耐金属熔体冲刷、滤渣质量好、使用方便等优良的性能，被广泛用于铸造过滤网，对金属熔体进行过滤净化处理，改善铸件质量，还可用于化工腐蚀液体的过滤和环境保护用烟叶过滤网以及消防等工业领域。

Not only do they come in all shapes, sizes and colours but the delicate flowers are edible too.The flowers are very hard to obtain so by growing your own you have access to these gems during the growing season. Jamie makes deep-fried courgette flowers stuffed with ricotta and mint.

为响应这口号，Jamie在后花园拣选了丰收的葫芦瓜作为今次私房菜的主题，首先他会用葫芦瓜加烟肉，再配上意粉作为主菜，然后会用将葫芦瓜刨成片状，配以烤好的鲜鱼作为一道简单的沙律。

The dash is a handy device, informal and essentially playful, telling that you're about to take off on a different tack but still in some way connected with the present course—only you have to remember that the dash is there, and either put a second dash at the end of the notion to let the reader know that he's back on course, or else end the sentence, as here, with a period.

它好像在说，你马上就要改变航向了，但并未完全脱离目前的航道——只是你别忘了你在这儿用过一个破折号，所以你需要在表达完自己的意思之后添上第二个破折号，好让读者知道他又回到原航道了，或者像我在这里所做的，用句号结束全句。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
