The fact that the compound, 2-methyl-2-di- methylaminomethyl-5--n-pentylidenecyclo- pentanone hydrochloride (T60) possessed little anticancer activity indicated that the Mannich bases that could formed a methylene group were necessary for anticancer activity.

当环戊酮环上的Mannich碱侧链位置上引入取代基时，抗癌活性显著降低，如化合物2-甲基-2-二甲胺甲基-5--亚戊基环戊酮盐酸盐（T60）几乎无抗癌活性。这说明Mannich碱能形成亚甲基是这类化合物产生抗癌活性所必不可少的条件。

The result showed that there existed spatial variability of soil nutrients. N, P and K had medium variability, which were mainly affected by routine fertilization measures. On the contrary, Organic matter has a smaller spatial variability; Soil nutrient had semi-variance structure, and model best fit included Circular, Pentaspherical and Exponential. There existed medium spatial correlation in N, P, K and OM.

结果表明，土壤养分性质均存在着空间变异性，受常规施肥措施影响较大的碱解氮、速效磷、速效钾变异相对较大；常规施肥有机质投放较少，变异相对较小；土壤养分性质均存在半方差结构，分别拟合Circular、Pentaspherical、Exponential模型，碱解氮、速效磷、速效钾和有机质均显示中等的空间相关性。

Liensinine is the primary pharmacal component of capsule for relaxing heart and stepping down blood pressure, which is developing by the second pharmacy factory of Tianjin DaRentang.

舒心降压胶囊是天津市达仁堂达二药厂正在开发的中药二类新药，其主要有效部分为莲心碱，在生产中传统的办法很难将莲心碱和叶绿素有效分离。

AIM: To investigate the effect of phellodendron and three kinds of its main components, which have asuppressive effect on the immune system, on the membrane fluidity of normal murine splenocytes.

The alkali lignin-based rigid polyurethane foam was prepared with alkali lignin extracted from black liquor as raw materials to replace 10%~25% amount of polyether polyols and polymethylene polyphenyl isocyanate.

以造纸黑液中提取的碱木质素为原料，代替10~25的聚醚多元醇与多亚甲基多苯基多异氰酸酯合成了碱木质素基硬质聚氨酯泡沫。

The company has strong technical force and advanced equipment, the main products protopine, liquid and chemical additives.

公司拥有雄厚的技术力量和先进的设备，主要产品为片碱、液碱和化工助剂。

Rumsfeld used the company's advanced technology, will be 48% ion-exchange membrane caustic soda concentration for 99% of the melting alkali, and then slice into protopine.

采用瑞士伯特拉姆斯公司的先进技术，将48％离子膜烧碱浓缩为99％的融熔碱，进而切片制成片碱。

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。
