时间延长

But in SD rats, cardiac muscle fibers were fractured seriouly , contracted to wavilness obviously, then muscle fibers fracture were contracted like entasia by the hypoxia time increased , injury intensify , all the changes refered SD rats compensatory mechanism can not be transferred in this hypoxia degree. 3. Exposed to 4% oxygen concentration, the cardiac muscle ultrastructure of Gansu zokors had serious injury after hypoxia 2h.

在4%氧浓度的低氧耐受实验中，甘肃鼢鼠在低氧2，4h后，心肌纤维收缩明显呈波浪状，低氧时间延长至6，8和10h后，心肌显微波浪状收缩由强逐渐变弱，并逐渐恢复至正常状态，说明鼢鼠心肌在6h以后对严重缺氧环境开始代偿性适应；SD大鼠2h组心肌纤维断裂严重，收缩加强成明显的波浪状，随着低氧时间得增加，4h组呈严重成挛状收缩，损伤加剧，提示SD大鼠在这一氧浓度下已经无法正常调动其代偿机制。3。

The mass loss patterns of four type litters fitted exponential model, and the decomposition rate could be well predicted by their lignin/N ratio.

结果表明：与对照相比，降水量减少条件下，蒙古栎叶凋落物的初始N、P、K浓度显著升高，初始木质素浓度显著降低，凋落物分解速率大，N、P、K矿化率高，N和P固持时间缩短；降水量增加情况下，其凋落物初始N浓度显著降低、木质素浓度显著升高，N、P、K矿化率低，N和P固持时间延长。4种类型叶片凋落物的质量损失过程均符合指数降解模型，分解速率可以由凋落物木质素／N来预测。

When subjects appeared complications, the visualization of kidney, the distinctness of kidney's outline, the uniformity of contrast agent degraded, perfuse time and empty time prolonged; besides, the TIC waved accompanied a lower or disappear second peak.Conclusions:⑴.

移植肾并发症的移植肾显影程度、轮廓清晰度、造影剂分布均匀度降低，灌注时间、排空时间延长；TIC上下波动，包络线光滑度及斜率降低，第二峰低平、消失。

The response of Pn to instantaneous lighfflecksdepended on induction state and lightfleck length;full induction shoots could response morerapidly than low or non-induction shoots;and the increase of lightfleck length could raise photoinduction thus to increase Pn.

针叶Pn对单个瞬时光斑的响应与光斑前的光诱导状态和光斑时间长短有关，充分诱导的针叶Pn光斑的响应要敏捷得多，光斑时间延长可提高光诱导状态。

Snake meats ── work as two snake copulations, will continue very long period of time (pallas pit viper to be possible to amount to 6~24 hours), will eat the snake meat to be able to cause the sex life effectively the time expand.

3蛇肉──当两条蛇交尾时，会持续很长一段时间(蝮蛇可达6～24小时)，食蛇肉能有效地使性生活的时间延长。

Lymphocyte transformation test demonstrated that all these vaccines stimulated significantly higher levels of T cell-mediated immunity with a duration of 2 weeks or so than that of control after initial immunization and the levels and durations could both be boosted by revaccination.

这七种疫苗免疫鸭的T细胞转化能力较非免疫鸭明显为高，但该作用只有约2周左右的持续期时间，此后便下降到与对照组相当的水平，二免可以使一免细胞免疫的水平增高和持续时间延长。

To verify whether the prolonged saccade latencies by TMS at two different time points really indicate the dissociation of the two mechanisms, the combination of TMS and model fitting was applied in this study to elucidate the issue.

有趣的是，眼球跳视反应时间是一个由许多历程相加的复合体，因此Juan等人(2008)所观察到的反应时间延长是否分别代表注意力及眼动准备需要更进一步的探讨。

However, when reaction time is fixed, this system can follow Lambert-Beer Law within visible spectrum. Furthermore, it can not be affected by temperature. Based on these findings, CTAB Turbidness Method, a quick method to determine hyaluronic acid contents in fermentation broth is established.

研究表明，随着反应时间延长，反应体系的吸光度逐渐升高，但当反应时间固定后，在可见光区反应体系能较好的遵循朗伯－彼尔定律，并且不受温度的影响。

TNF-α and IL-10 plasma concentrations were measured by ELISA. Results: Plasma concentrations of TNF-α fell significantly from (419.4±77.5) pg/ml to (168.1±55.4) pg/ml after treatment, much lower than that of MODS group (P.05), but we did not find TNF-α in the ultrafiltrate. The start of HVHF was associated with a significant and sustained fall of IL-10, which came to the lowest level in the 6th hour after new filter was used, thereafter remained stable during the observation period.

姑果：HVHF组治疗后血浆TNF-α浓度明显下降，从(419.4±77.5)pg/ml降低到(168.1±55.4)pg/ml，各时间点与MODS组有显著差异(P.05)，但滤液中未检测到TNF-α治疗开始后血浆IL-10明显下降，6h达到最低点，此后维持在稳定状态，滤液中能检测到IL-10，随治疗时间延长其滤过系数降低。

The GLDH gene expression showed a continuing reinforcing trend after morphine injection compared with control group, even after drug withdrawal. The ADA mRNA contents in morphine group Ⅰ,Ⅱ and withdrawal group Ⅰ,Ⅱ were 2.65,1.89,1.18, and 0.87-fold of that in control group dividedly. The ADA gene expression increased after morphine injection and fell gradually after withdrawal.

结果：吗啡Ⅰ、Ⅱ组及停药Ⅰ、Ⅱ组大鼠肝脏GLDH mRNA含量分别为对照组的1.02、1.09、1.16及1.46倍，吗啡给药大鼠肝脏中GLDH基因表达随给药时间延长而持续增强，自然停药一定时间内大鼠肝脏中GLDH mRNA含量仍持续增高；吗啡Ⅰ、Ⅱ组及停药Ⅰ、Ⅱ组大鼠肝脏ADA mRNA含量分别为对照组的2.65、1.89、1.18及0.87倍，吗啡Ⅰ、Ⅱ组大鼠肝脏ADA的基因表达均比对照组明显增高，自然停药后大鼠肝脏ADA表达逐渐下降，停药7 d时下降至接近对照组水平。

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
