There was a little difference betweenphotosynthesis characteristic of the two varieties,response of Jiamusi to low temperature andpoor light was more sensitive than that of Longjiao No.2 and decreased pronouncedly withdecreasing light.6.EC and MDA of pepper leaves increased under low temperature and poor light,therewere no significant differences between them with decreasing light at 21-23℃/8-10℃,butthey were increased dramatically at 15-20℃/5-6℃.So we can speculate that lowertemperature was the direct reason resulted in cell membrane lipid peroxidation.7.No significant difference of SOD activity was observed under suboptimal temperatureand poor light21-23℃/8-10℃;150μmol·m~(-2·s~(-1),but SOD and POD activity substantiallydeclined with lowering temperature and light as well as treatment time.8.Under suboptimal temperature and lower light,proline accumulated to increaseosmotic regulation capacity and alleviate chilling damage.Soluble carbohydrate of pepper leaves decreased progressively and significantly with decreasing temperature and lightintensity as well as longer treatment time.So we think that synthesis and transport ofphotosynthetic product were inhibited by low temperature and poor light as solublecarbohydrate was important component of photosynthetic product.

两个供试辣椒品种之间的光合特性略有差异，佳木斯对低温弱光的反应比陇椒2号敏感，尤其随光照降低，其光合作用显著降低。6、低温弱光胁迫下，辣椒叶片的相对电导率和丙二醛含量都有不同程度的提高，在偏低温下，随着光照减弱，相对电导率和丙二醛含量差异不显著；在极端低温下，随着光照进一步减弱，相对电导率和丙二醛含量明显提高，随着处理时间延长，同一温度下，随着光照降低，叶片丙二醛含量也显著增加，由此可初步判断，低温是导致细胞膜脂过氧化的直接原因。7、经偏低温较弱光21～23℃／8～10℃、150μmol·m~(-2·s~(-1)处理后，辣椒叶片的超氧化物歧化酶活性变化与对照无显著差异，但随着温度、光强的逐步降低和处理时间的延长，SOD、POD活性显著降低。8、在偏低温较弱光下，辣椒能积累更多的脯氨酸，增强渗透调节，减轻低温冷害。

At the speed the muons were travelling a factor of thirty is exactly the value expected on the basis of the above formula for time dilation.

在这种速度下运转的μ介子延长了30倍的寿命，正好符合根据上面时间延长公式的预计数值。

He laughed as he went on to describe his dreams about relativity land-how the streets had become visibly shrunk, and how the time dilation effects had been greatly magnified .

他接着笑了讲述了他的梦境，关于那个相对论的国家-街道如何明显变得缩窄了，还有时间延长效应如何被大大的延长了。

The severity of ethological asymmetry increased with time and trended steady 28 days later.

Apo诱发的PD模型大鼠旋转行为次数随损毁时间延长而增加，与其行为不对称性随时间延长加重的表现一致。

In order to study the mechanism of the inhibitory effect of salvia miltiorrhiza and tetramethyl pyrazine on scar fibroblast, the DNA content of fibroblast and the all distribution in cellular cycle was measured by FCM. The hypertrophic scar tissue of chest was chosen for primary culture of fibroblast.

摘 要 应用流式细胞光度分析法测定丹参和川芎嗪对体外培养的瘢痕成纤维细胞DNA相对含量和细胞周期时相变化，发现药物在一定浓度作用下，DNA指数无明显变化；丹参使C2-M期细胞分布增多，G2-M期延长；川芎嗪使G2-M期细胞分布增多，G2-M期、S期延长；药物使细胞群体倍增时间延长，与浓度呈明显直线正相关。

The conclusions were that the inhibitory effect of SM was the result of inhibiting the mitosis of cells and the cellular cycle be at a standstill in G2-M stage.

RESULTS: The content of marrow DNA decreased gradually with the prolongation of postmortem interval and gradated to its minimum after 10 d after death.

结果： 人死亡后1～10 d，Feulgen染色阳性产物随死亡时间延长逐渐减少，胸骨骨髓细胞核DNA含量随死亡时间延长呈规律下降，DNA染色逐渐变浅淡，至死后10 d已基本观察不到。

It gradually increased with prolongated infection time. In the spleens of infected mice, IL-4,IL-5 and IL-10 were also elevated. However, their ranges were obviously lower than those in livers. In the colons of infected mice, IL-4,IL-5 and IL-10 slowly increased with prolongated infection time.

结果在老婆感染小鼠肝脏IL-4，IL-5，IL-10明显成年人高于正常对照(P＜0.01)，并随老婆感染时间的延长而逐步升高；在脾脏IL-4，IL-5，IL-10亦升高，但其幅度明显成年人较肝脏为低；在结肠IL-4，IL-5，IL-10随老婆感染时间延长呈缓慢升高趋势。

After sustained exposure of 2h to 90 dB the total time of black-red digit test was prolonged and the time performance decreased, the reaction time of attention range also was prolonged.

但90dB、2h的持续暴露，可引起黑红数字测试的总时间延长，时间绩效降低，注意广度测试的反应时延长。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
