Grew on the normal temperature, it was shown that the deposits of calcium antimonate being the indicator for Ca(superscript 2+) localization mainly concentrated within the vacuoles and intercellular spaces and there was also some Ca(superscript 2+) deposits in cell walls. But when Garyota urens L. was treated by the temperature of 2℃ for 48 h, the level of Ca(superscript 2+) increased in cytoplasm and plasma membrane, but decreased in vacuoles and intercellular spaces considerably. At the same time, the ultrastructure of chloroplasts suffered from chilling: the membrane of chloroplasts had been damaged, the layer of thylakoids was exiguous and unclear, the photosynthetic rate decreased evidently. And when Garyota urens L. was treated by the temperature of 2℃ for 120 h, the deposits of Ca(superscript 2+) mainly concentrated within the cytoplasm, nucleus and plasma membrane and there was also some Ca(superscript 2+) deposits in vacuoles, and the ultrastructure of some cells was simultaneously damaged severely: Chloroplasts structure, vacuole membrane and nuclear membrane had been damaged fully, the structure within the cell had become unclear, and the cell only have respiration.

研究结果表明，未经低温处理的董棕幼苗叶肉细胞，焦锑酸钙沉淀颗粒大量出现在液泡和细胞间隙中，细胞壁中也可见少量沉淀，而细胞基质中则看不到焦锑酸钙沉淀；经2℃ 48 h低温处理后，细胞基质和细胞膜上焦锑酸钙沉淀增加，而液泡和细胞间隙中的焦锑酸钙沉淀则显著减少，并且超微结构已初步显示出寒害的特徵，叶绿体外膜部分破损，类囊体片层稀疏且排列不规则，光合速率明显下降等；经2℃ 120 h低温处理后，细胞间隙内的焦锑酸钙沉淀极少，有的也紧贴在细胞外壁上，而细胞基质和细胞膜上则分布有非常多的焦锑酸钙沉淀，在核基质和液泡中也可见到少量的焦锑酸钙沉淀，并且超微结构遭到了显著破坏，叶绿体结构完全被破坏，核膜与液泡膜严重破损，内部结构模糊，细胞只表现为呼吸作用，不进行光合作用。

RESULTS: Primarily cultured cells were colored with CD44 in-situ hybridization, kytoplasm as buffy and nucleus as blue by counterstain.

ERK1/2 immunohistochemistry positive staining coloration in cornu dorsale medullae spinalis of rats was Buffy color.Positive cells distributed in gray nucleus that nerve cell concentrated,and deep staining region localized at the nucelus of neurocyte.

针刺前后脊髓未见明显形态学改变。2、光镜下观察，大鼠脊髓背角ERK1/2免疫组化反应显色呈棕黄色，阳性细胞分布于脊髓灰质神经元集中的部位，针刺后深染部位向胞核集中。

Methods:Surgery was performed on kittens during the critical period (age 2～4 wks) to induce esotropic MS by sectioning the lateral rectus muscle of one eye and MD by lid suture.

结果：在正常发育幼猫的视皮质和外侧膝状体主要是在神经元核浆，呈深棕黑色免疫阳性反应，胞浆淡染。

Years , and of the normal nasal mucosa from 8 patients (male 4, female 4, aged 22-43 years, mean age 32 years). Resutls showed that the ER+ cells were morphologically plasma positive and nuclear negative and the plasma contained a large number of dark brown monomorphic granules.

结果显示：鼻息肉和慢性炎性鼻粘膜中，含有一种形态独特的雌孕激素受体阳性细胞，该阳性细胞呈圆形或椭圆形，为胞浆阳性，胞核阴性并且胞浆中含有大量的棕褐色颗粒。

The induced MSCs were found to be positive for desmin and specific myoglobulin of the skeletal muscle.

MSCs免疫组织化学法测定CD44反应阳性，胞质呈棕褐颗粒，核周明显，CD34呈阴性反应；诱导后MSCs结蛋白、骨骼肌特异肌球蛋白均为阳性表达。

Fruit a drupe-like pome, red, brownish red, or orange to black, with persistent, incurved, fleshy sepals, containing pyrenes; pyrenes (1 or)2–5, bony, 1-seeded; seeds compressed; cotyledons plano-convex.

果一核果象梨果一样，红色，棕红色，或橙到黑色，具宿存，弯曲，肉质的萼片，包含果核；果核(1或者)2-5，多骨，1种子；种子压扁；子叶平凸。

A planet on the other hand is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.

行星演化与恒星不同：恒星形成之后，周边的气体尘埃云冷却之后凝结形成，成为行星雏形，众多小行星雏形聚合碰撞，演化成成熟的行星；没有内部的核聚变；质量超过木星13.6倍，就会产生核聚变，如果还未至木星86倍，尚处于棕矮星的阶段，将会向恒星演化；持久的核聚变需要足够大的质量来支撑，温度也不足支撑氢向氦的转变。

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。
