In the light of the palenenvironmental significance reflected by the radiolaria, graptolite, brachiopod, sponge spicule and the rock character, it's suggested that the grayish green mudstone at the basal Wufeng Formation of the Goujiaya section would be probably deposited in 60 to 100meters deep water, the Guanyinqiao bed in 50 to 80meters deep, and the radiolaria-bearing silicalite from Wufeng Formation in water with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level change cycles, the change range of every one of the 5 cycles could be further conjectured. They were in ascending order: 20～120m, 80～130m, about 150m, 50～250m, and in excess of 200m.

根据放射虫、笔石、腕足类、海绵骨针以及岩性等对古环境的指示意义，认为五峰组底部灰绿色泥岩段产出时水深约60-100m，观音桥层水深约50-80m，在晚奥陶世最大海侵期(对应于T.typicus亚带下部)，水深约400m，五峰组含放射虫硅质岩沉积时最小水深约200m，结合以上海平面变化的5次旋回，从而推算出各旋回海平面的变化幅度：在第①旋回，海平面变化范围大致为20～120m；在第②、第③和第④旋回中，海平面变化分别为80～130m、大约150m和50～250m；第⑤旋回的海平面升降幅度大于200m。

The path through such a wormhole is called a closed timelike curve, and a wormhole with this property is sometimes referred to as a timehole.

通过这样一个虫孔的路径被称做一闭合类时曲线，而且具有这个特性的一个虫孔有时被称为"时间洞"。

The efficacy of aromatic diamidines in the treatment of protozoal diseases was first recognized in the 1930s by investigators searching for agents with therapeutic activity against African trypanosomiasis .

早在1930年，人们在寻找治疗非洲锥形虫症药物时首先发现了芳香二脒类化合物具有治疗原虫疾病的作用，临床试验表明戊烷脒及其类似物对非洲人早期锥形虫症和黑热病具有疗效。

Any of various arthropods of the class Chilopoda,which includes the centipedes .

虫各种类似的节肢类动物，如蜘蛛，百足虫或蝉

According to the basic information such as origin, agricultural characters of different germplasm, 444 representative domestic cultivars, belonging to 13 species or varieties, 7 genus of cucurbitaceae respectively, were selected as experimental materials to identify their resistance to root-knot nematode using the inoculation method of infected soil. Results showed the resistance distribution of different cucurbit crops.

根据不同种质的来源地、农艺性状等背景信息，从国家蔬菜种质资源中期库中选取具代表性的444份主要瓜类作物地方品种，分属葫芦科7个属的13个种或变种，采用病土接种法进行苗期根结线虫抗性鉴定，得出了不同葫芦科作物对南方根结线虫的抗性分布范围。

The main species of the community were Isaria cateinannulata, I. farinosa and Beauveria bassiana.

该林区虫生真菌群落的主要成分是环链棒束孢、球孢白僵菌和粉棒束孢，虫生菌种类较少，较为单一。

The contents of rutin, isoquercitrin and quercetin were the highest in petal, but lower in calyx, bract and cotton boll. Moreover, the tot...

不同组织不同生长期的主要抗虫黄酮类化合物含量有一定的差异，所起的抗虫作用也有所不同。

The results from statistical analysis of variance indicated that Bt toxin in Bt transgenic cotton had no negative effect on synthesis of flavonoids (mainly rutin, isoquercitrin and quercetin ).

显著性分析发现，外源Bt杀虫蛋白表达对棉花原有的芸香苷、槲皮素和异槲皮苷等抗虫黄酮类化合物不存在不利的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
