Plant diseases and insect pests of safflower model wood is less, be like an environment not beautiful, can produce thorn E and harm of red wax interpose, can spray to plant in 5-7 month to red wax Jie the oxidation happy fruit of the 40 ％ of 1500 times, LO 15 days one, keep clear of thoroughly comparably scale insect; High to thorn usable also and same method gush is treated.

红花楷木病虫害较少，如环境不佳，会发生刺娥和红蜡介危害，对红蜡蚧可在5-7月向植株喷洒1500倍的40％的氧化乐果，lO一15天一次，可比较彻底地清除介壳虫；对刺峨也可用同样的方法喷治。

The study was carried out in two breeds of sheep, Indonesia Thin Tail and Merino, both infected with F. gigantica. Kinetic analysis of Fasciola gigantica specific antibody responses revealed that resistant ITT do not produce a parasite specific IgG2 response; whereas susceptible Merino sheep produce a high parasite specific IgG2 response.

以印尼短尾羊和美利奴细毛羊两种品系的绵羊为实验动物，研究动物感染巨片形吸虫后所产生的抗体依赖性细胞介导的细胞毒反应的免疫应答。

However, the high abundance of ostracodan and foraminiferan was distributed in deeper water while the high abundance of nematodan was presented in coastal water, and they could meet the distribution rules of these fauna groups.

但总的来说，介形类和有孔虫的高丰度区主要分布于洋山港区附近的深水区，线虫主要分布于近岸海域，这符合它们大体的分布规律。关键词洋山深水港；小型底栖动物；丰度；生物量；分布

An expression vector was constructed with a safe marker gene, 6-phosphomannose isomerase, and an insect-resistant gene, Galanthus nivalis agglutinin, was used in rice genetic transformation in the present study.

采用农杆菌介导法将来源于大肠杆菌的6-磷酸甘露糖异构酶安全选择标记基因和雪花莲凝集素抗虫基因构建于同一表达载体上进行遗传转化，获得带有安全标记基因的抗褐飞虱转基因植株。

Detailed biostratigraphic study reveals that the sequence could contain 3 Ostracoda assemblages, 3 Lamellibranchiata and Gastropoda assemblages and 8 sporopollen assemblages, whose ages are discussed on the basis of radioactive dating.

通过详细的生物地层学研究，共划分出 3个介形虫化石组合带、3个瓣鳃类及腹足类化石组合带和 8个孢粉组合带，结合各组同位素年龄数据，对其形成时代进行了探讨。

Many methods for sample preparation have been applied in stable isotope measurements of ostracode shells from lake sediments.

由于湖泊生物碳酸盐样品不同的前处理方法可能会影响到稳定同位素测试结果的重现性和辨析率以及实验室之间数据的可比性，采用有效的方法对介形虫壳体进行预处理是保证介壳稳定同位素测试的一个关键环节。

Stable isotopic composition of fossil ostracode is used as an ideal proxy for paleo-lake sedimentary environments.

介形虫化石壳体被认为是反映古湖泊沉积环境的理想对象。

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。
