潜伏期

The sensibitity to CO2 is higher than that to peripheral chemoreceptor.but the latent period of reaction to sudden change of PCO2 in the arterial blood is longer than that of the peripheral chemoreceptor.

c。 对CO2的敏感性却比外周化学感受器高，但它对动脉血中PCO2的突然改变所引起的反应的潜伏期却比外周感受器长。

Chlamydia and Mycoplasma invasive human urogenital tract, there are 1 to 3 weeks or longer incubation period.

衣原体和支原体侵入人体泌尿生殖道后，都有1～3周或更长的潜伏期。

The incubation period for both can last from 7-10 days. The period of communicability is the first 3 weeks of illness.

白喉及百日咳的潜伏期均可持续7-10天，在发病后的3周内具有传染性。

Methods Three doses of etomidate were administered intraperitoneally. Five minutcs later, convulsion was induced by electricity or drugs . The convulsant latency, duration of tonic state, incidence of convulsion, mortality and survival time were noted.

以电刺激或致惊剂〔士的宁、N-甲基－D-天冬氨酸、利多卡因〕建立不同类型的小鼠惊厥模型，观察腹腔注射3种剂量的依托咪酯对小鼠强直性惊厥潜伏期、持续期、惊厥发生率、小鼠死亡率以及小鼠存活时间的影响。

Days after a convulsant dose of KA, the seizure susceptibility were found in KA+NS group and enhanced in KA+PL017 group, whereas significantly decreased in KA+β-FNA group (p.01).β-FNA prolonged the latency and reduced the stage of seizures in dose-dependent manner.

结果显示，一次给予惊厥剂量KA后7天，KA+NS组的癫癎发作敏感性形成；MORs激动剂组（KA+PL017）动物出现癫癎发作敏感性增强；与上述两组比较，MORs拮抗剂组动物癫癎发作敏感性明显降低（p.01），β-FNA以剂量依赖方式延长癫癎发作的潜伏期、降低发作级别。

Methods Three doses of etomidate were administered intraperitoneally.Five minutcs later,convulsion was induced by electricity or drugs ［strychnine.N-methyl-D-aspartate.lidocanine］.The convulsant latency,duration of tonic state,incidence of con-vulsion,mortality and survival time were noted.

以电刺激或致惊剂〔士的宁、N-甲基-D-天冬氨酸、利多卡因〕建立不同类型的小鼠惊厥模型，观察腹腔注射3种剂量的依托咪酯对小鼠强直性惊厥潜伏期、持续期、惊厥发生率、小鼠死亡率以及小鼠存活时间的影响。

RESULTS:POT at doses of 200 mg/kg had significant antagonistic effect on the cough caused by mixture of hista...

结果 ：POT 2 0 0mg/kg对氨雾引起的小鼠咳嗽无明显的影响；对乙酰胆碱和组胺混合液引起的豚鼠支气管收缩有极显著的抑制作用(P 。0 0 1 )；对小鼠PCA反应的抑制率为 3 2 。79%；可显著延长卵白蛋白所致的致敏豚鼠呼吸困难、抽搐和跌倒的潜伏期(P 。0 0 1 )。

Methodssmear 0.25% croton oil＼acetone ag on the back of kunming mice,and observe the growth condition of papilloma,then record the quantity of tumor-bearing mice and the quantity of tumor in each mice.results20-ginsenoside rh2 prolonged the incubation of tumor, reduced the quantity of tumor-bearing mice and decreased the amount of tumor in each mice.conclusion20ginsenoside rh2 has obvious anti-papilloma effect on the mice skin.

结果20-人参皂苷rh2对小鼠皮肤乳头状瘤有明显的抑制作用，可使肿瘤发生潜伏期延长，使化学致癌物诱发的荷瘤动物数明显减少，每鼠荷瘤数显著下降。结论20r 人参皂苷rh2在预防癌症的发生和发展方面有重要的作用，也是很有前景的新型抗癌药。

D'Arcy also questioned the response-time factor cited by the report."Most of our subscribers have actually increased the performance on their search -- there might be a slight difference in latency like a 10th of a second vs. a 12th of a second, but I've never heard that as part of a sales cycle," he said. D'Arcy claims one large company is currently in the process of deploying MessageOne to improve performance after two on-premise products had failed.

D'Arcy 同时还质疑了报告中列举出来的响应时间因素，"实际上，我们的大多数用户反应在搜索过程中产品表现不错—可能在潜伏期略有不同，例如一秒钟10次以及一秒钟12次，但是我从来没听过在一个销售周期中它成为什么问题，" D'Arcy 还宣称一家大公司目前正在部署 MessageOne 产品，用来改善之前的2次产品失败。

The average delitescence was 12h. Common symptoms were abdominal pain and diarrhea.

潜伏期平均12h；临床症状以腹痛、腹泻为主。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
