Results showed that in the frontal cortex, the subcortex and the cerebellum, the mitochondrial O2.- generation peaked at 4 hr after MPTP treatment.

经本论文实验结果我们发现：小白鼠经MPTP处理后，在大脑额叶、次皮质区和小脑的粒线体产生O2·-的速率在四小时达最大值。

When PO3-4-P concentrations exceeded 0.010mg·L-1, the TAPA was significant difference (P＜0.01).②The contents of APA in phytoplankton, bacteria and dissolved were different. The ratio of DAPA to TAPA was the highest and BAPA was the smallest.

水体中的碱性磷酸酶在不同粒级组分中的分布差异明显，其中以溶解性碱性磷酸酶活性所占的比例最大，浮游植物体中的碱性磷酸酶活性所占的比例次之，细菌体中的碱性磷酸酶活性所占的比例最小。

To the world of green grass every tree, every spring, a hope that the initiative, watering the desert oasis of the nation, the rise and fall of the Chinese hold the responsibility, you, as hard a gardener, cultivating the land of the Green Grass stained, support tree of heaven and earth.

为了世界上每一棵小草的绿意，春天萌动着每一粒希冀，浇灌民族沙漠的绿洲，托起华夏兴衰的重任，你们，像辛勤的园丁，培育出染绿大地的芳草，支撑天地的树木。

It was shown from the results that emulsifier TP-Ⅴ which was prepared by PEG 4000 reacted with TME, in the molar ratio of TME to PEG 2:1, at about 110℃ for 1 h, catalyzed by boron trifluoride diethyl etherate, has a very good emulsifying impact for TME. Particle size distribution of the emulsion was homo-geneous and viscosity of the emulsion was small.

实验结果表明，以M相对适中的PEG4000与TME按物质的量比2： 1、在催化剂三氟化硼乙醚作用下、110℃左右反应1h合成的乳化剂TP-Ⅴ，对萜烯基环氧树脂具有很好的乳化效果，制备的乳液粒子粒径均一度较高，乳液表观黏度较小。

An experimental study of the influence of pressure on Umf and bed expansion height by the photographing with a camera was carried out in a fluidized bed of 60mm i.d.in the range of operating absolute pressure 0.1MPa~1.5MPa with two kinds of different size particles .

利用摄像技术在φ60mm×800mm压力为0.1MPa～1.5MPa的冷模加压流化床实验装置上，对两种不同粒径颗粒的最小流化速度和床层膨胀高度进行了研究。

The reaction rate was mainlyinfluenced by temperature but nearly uninfluenced by concentration of H2S and particle scaleswhen they were small.

温度对预硫化反应速率的影响较为显著；在较低的硫化氢浓度和较小的催化剂粒径范围内，预硫化宏观反应速率几乎不受二者的影响。

Microspore abortion of H9A occurred in the early uninucleate stage. The tapetum cells were in extreme hypertrophy so that tetrads were extruded to crack and break down and could not form normal uninucleate pollen grains; the abortion type was sporophyte.

结果表明，雄性不育材料H9A的小孢子败育发生在单核前期，由于绒毡层细胞极度膨胀，四分体受挤压后破裂并降解，无法形成正常的单核花粉粒，属于孢子体败育。

The accumulation of starch, vacuolation of multinucleate microspores and degeneration of anther wall affected microsporic embryogenesis.

淀粉粒的积累，多核小孢子的液泡化以及花药壁的衰退都可影响雄核发育。

He takes out a little bottle. takes out a pill and puts it into Snow White's mouth.

从身边掏出一只小瓶子，倒出一粒丹药，上前，扶起白雪，喂到她嘴里。

Wind-pollinated flower is the major factor in hay fever allergies due to small pollen grain, light, dry and easy floating and proliferation in the air.

风媒花为花粉症过敏的主要因素，因为花粉粒小、质轻、乾燥、易在空气中扩散漂浮，一旦有过敏体质者，极易发生过敏症状。

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。
