Results: From the third to sixth month of gestation, some small NOS positive cells could be seen in the lamina propria mucosae. With the fetal age increased, the number of NOS positive cells increased too, and at the same time, the positive reaction of NOS increased gradually.

结果：第3~6个月龄时，胃粘膜固有层内皆可见胞体较小的NOS阳性细胞分布，随着胎龄的增加，NOS阳性细胞数目逐渐增多，染色逐步加深。

In 16 month- aged mice, TP (50, 200mg/kg, ig) also showed potentiating effect on PFC response.

TP（200，400mg/kg，ig）可促进正常小鼠的PFC反应，并可对抗环磷酰胺（10mg/kg ip）和冷水（14±1℃）游泳应激所致的PFC反应降低；TP（50.200mg/kg）可使16月龄老年小鼠低下的PFC反应恢复至正常3月龄年轻小鼠水平。

At the salinity of 30, the animals respired and excreted at a low level. The respiration rate and ammonia excretion rate increased significantly at higher salinity of 35 and at lower salinity of 23 for the juvenile group or 20 for the one year old group.

幼参在23~30盐度、1龄参20~30盐度范围内，耗氧率和排氨率随着盐度的升高而降低，当盐度升高至35时，两者都明显升高（以盐度30为对照），当盐度降至20、16（1龄参）时，刺参耗氧率和排氨率均降低。

The plasmid pcDNA3.1-3-1E and pcDNA3.1 was respectively used to immunize SPF chicks by injection intra-muscularly in thigh muscle at 14 and 21 days of age.Chicks in each group except that in the unchallenged control group were challenged with 5×104 E.acervulina sporulated oocysts at 28 days post-inoculation,and the immune protective efficacy was observed.

将构建的重组质粒以及空载体质粒分别于14、21日龄分2次经腿部肌肉注射免疫SPF雏鸡，28日龄除非免疫非感染对照组外各组攻击性感染5×104个堆形艾美球虫孢子化卵囊，观察真核表达质粒对球虫感染鸡的免疫保护作用并探讨其免疫保护机理。

There was no apparent structure of vasicular bundle sheath in the leaves. Thick cuticle layer was found on both abaxial and adaxial surfaces.

荔枝叶片叶肉组织内细胞的排列，除了在5天叶龄的幼叶排列非常紧密之外，其余叶龄的叶肉组织都会发现有空隙的存在。

The proper alkaline content was in favor of compressive strength. The chemically combined water of paste without activator decreases with the increase of fly ash content, the content of Ca2 decreases after 28d. The increase extent of chemically combined water of pastes with NaOH is higher than that of without activator, and the paste with Ca2 is the same. The XRD peak of Ca2 of paste without activator is high at early age, and the peak of mullite and quartz has less change along with age. When NaOH is added, the peak of quartz of fly ash has clear drop. The surfaces of fly ash activated has eroded trace at 7 d.

研究结果表明：适量碱的掺入对强度有利；未掺激发剂浆体的化学结合水量随着粉煤灰掺量的增加而减少，Ca2含量在28d后开始下降；掺NaOH浆体的结合水量随龄期增长的幅度比未掺激发剂的浆体的大，而掺Ca：试样变化较小；未掺激发剂的水泥－粉煤灰体系在早期Ca2的峰值较大，且粉煤灰中的莫来石和石英晶体的衍射峰随龄期变化不大；NaOH掺入后，28d时，粉煤灰中的石英晶体衍射峰明显下降；时于掺激发别的试样，在7d时粉煤灰颗粒表面已被腐蚀。

China has a long and venerable tradition of indulging its rulers' artistic endeavours – from the sensitive emperor aesthetes of the Song dynasty to the artistic ambitions of Madame Chiang Kai-Shek, whose husband lost China to the Communists in 1949 but who was always able to find buyers for her watercolours.

中国长久以来就拥有容许其统治者进行艺术尝试的威严传统——从感情细腻的宋朝君主的唯美主义，到宋美龄(Madame Chiang Kai-Shek)的艺术抱负。宋美龄丈夫在1949年被共产党打败，逃离了中国大陆，但她总能找到买家购买她的水彩画。

The results show that the air exchange efficiency can meet the need of indoor air quality, the airflow and air age distribution is symmetrical among apartments, and the best air quality area is the lower berth, the middle berth the next and the upper berth is the worst, and reasonable airflows will make for improving indoor air quality.

研究结果表明：车厢内的换气效率基本符合室内空气品质的要求；整个车厢内流场及空气龄关于隔间存在良好的对称性；旅客区域的空气品质优劣排序依次是：下铺区域、中铺区域、上铺区域；气流组织的合理分布能够缩短空气龄，改善室内空气品质。

生物测定结果表明，幼虫死亡率依多角体浓度和虫龄而变化，在25℃条件下，3龄幼虫的致死中浓度为1×10~(5.3)多角体/毫升。

Studies on digestible methionine requirement of fattening egg-type cockerels Experiment with corn-soybean meal type ration was conducted to study methioninerequirement of fattening egg-type cockerels. Methionine level of basic diet were 0.34% during former period (0~6 week) and 0.28% during latter period (7~10 week).

育肥蛋公雏可消化蛋氨酸需要量的研究用玉米—豆粕型基础日粮进行育肥蛋公雏蛋氨酸需要量的试验。0～6周龄和7～10周龄基础日粮的蛋氨酸含量分别为0.34％和0.28％。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.
