A new type of separation and purification method for isolating puerarin was developed using chelate complex chromatography.

中文内容：摘要：建立了采用配位色谱柱从葛根素浸膏中分离纯化葛根素的方法。

The chimney-sweep and the little shepherdess looked piteously at the old Chinaman, for they were afraid he might nod; but he was not able: besides, it was so tiresome to be always telling strangers he had a rivet in the back of his neck.

扫烟囱的人和牧羊女望着这位老中国人，样子很可怜，因为他们害怕他会点头答应。但是他现在不能点头了，他同时又觉得怪不好意思告诉一个生人，说自己颈子里牢牢地钉着一根钉子。因此这一对瓷人就成为眷属了。他们祝福老祖父的那根钉子；他们相亲相爱，直到他们碎裂为止。

Alternaria-induced necrosis and chlorosis of all leaves were studied in mycorrhizal and non-mycorrhizal plants over time course and at different soil P levels.

长期在菌根和非菌根植物和在不同的土壤P水平上，对所有的由早疫病菌诱导的坏疽和萎黄的叶片进行了研究。

High-pressure trunk-injection of iron fertilizer was reported to be effective to correct chlorosis, but the mechanism involved was unknown.

结果表明，铁肥树干强力高压注射，主要以二价铁(Fe2+)沿中央木质部的导管运输，大部分向下运输，使铁在根中大量贮存；向上运输较少，运输速度为每小时数百厘米，矫正缺铁失绿症的速度比根系输液慢，但由于根中贮存大量的铁，持效期较长。

That's Roman wormwood —— that's pigweed —— that's sorrel—— that's piper-grass —— have at him, chop him up, turn his roots upward to the sun, don't let him have a fibre in the shade, if you do he'll turn himself t' other side up and be as green as a leek in two days.

这是罗马艾草，——这是猪猡草，——这是酢酱草，——这是芦苇草，——抓住它，拔起它，把它的根翻起来，暴露在太阳下，别让一根纤维留在荫影中间，要不然，它就侧着身子爬起来，两天以后，就又青得像韭菜一样。

This study has hypothesized that high concentration of nitrate, acetic and chorine ions in the scrubbing water lowers the water vapor pressure which in turn reduces the relative humidity of the scrubber outlet from 90~100% to below 80%. As a result, nitric acid can't absorb water to grow into visible white smoke particles.

本研究推论白烟消失的原因是因为含有高浓度硝酸根离子、醋酸根离子及氯离子之洗涤水蒸气压变低，使得洗涤塔出口的相对湿度由90~100%降低至80%以下，因而使得硝酸无法反应及成长成可见之白烟微粒。

In the 20 yr forest, 304. 6gm〓 C and 11. 6gm〓 N are inputted to the soil. In the 80 yr forest, 502. 3gm〓 C and 17. 2gm〓 N are inputted to the soil. In the climax forest, 430.3gm〓 C and 11. 9gm〓 N are inputted to the soil. Along with forest succession, the C inputted to the soil B layer by fine root increases because of the deepening of root depth distribution.

白桦山杨幼林、白桦山杨成熟林与原始阔叶红松林中，细根每年向林地周转的碳量分别为304.6gm〓、502.3gm〓、430.3gm〓，氮量分别为11.6gm〓、17.2gm〓、11.9gm〓；其中，随着演替的进行，由于根系分布的加深，细根每年向土壤B层周转的碳量会逐渐增加。

A combined process of chemical control of clubroot in Chinese cabbage at different growth stages was carried out. The test results showed that fluazinam and cyazofamid were effective pesticides for control of clubroot.

在大白菜的不同生育期，采用多种杀菌剂和不同的防治方法防治大白菜根肿病，试验结果表明： 50%氟啶胺和10%氰霜唑能有效防治大白菜根肿病，其防治效果优于其他化学药剂。

Plasmodiophora brassicae causes clubroot of cabbage and related brassicas .

如芸苔根肿菌引起的甘蓝和芸苔根肿病。

Tom and me was to sleep in the same room and bed; so, being tired, we bid good-night and went up to bed right after supper, and clumb out of the window and down the lightning-rod, and shoved for the town; for I didn't believe anybody was going to give the king and the duke a hint, and so if I didn't hurry up and give them one they'd get into trouble sure.

队伍走过时，只见国王和公爵给骑在一根单杠上——其实，那只是我认为是国王和公爵，因为他们遍身给涂了漆，粘满了羽毛，简直已经不成人形——乍一看，简直象两根军人戴的狰狞可怕的粗翎子。

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。
