使人工化

With a method similar to chandlers, artificial red and white thrombi of rabbit in vitro were prepared, and then separately infused into jugular vein of the same rabbit to form red and white thrombi in its pulmonary circulation.

采用与chandler氏相似的方法，制取家兔体外人工红、白血栓，然后分别注入同体家兔颈静脉，使之形成肺循环红、白血栓。在48小时内，给予实验动物某种活血化瘀中药或对照生理盐水。

Noggin induces the nerve tube formation. It binds and inactivates members of the transforming growth factor-beta superfamily signaling proteins, such as bone morphogenetic protein-4 (BMP4). Proximal symphalangism (SYM1) and multiple synostoses syndrome (SYNS1) are related to noggin mutations.

Noggin能使紫外线人工腹侧化的爪蟾胚胎重新恢复背-腹的身体轴；在神经系统中诱导神经管的形成；减弱包括骨形态发生蛋白在内的转化生长因子信号蛋白的活性，从而控制骨的生长；调控生殖系统的发育。

This paper has studied the impacts of rubber plantation on the fragmentation of tropical forests and its substitution for natural forests.

研究表明：西双版纳橡胶种植既有明显的地域分布和地带分布差异特征，也有很高的时空动态度；橡胶种植对土壤侵蚀作用不明显，但是使周边环境破碎度加大，热带森林异质性自然景观向单一人工斑块化景观发展；西双版纳橡胶种植获得了巨大的社会效益和经济效益，也对热带森林的稳定性和多样性造成威胁。

When the synovial line structure appeared around the silica gel bag, we observed the bursa figure, studied its histology and ultra structure, detected the activity of uridine diphosphoglucose dehydrogenase in synovial lining structure. At the same time, the expression of vascular cell adhesion molecule 1 (VCAM-1), CD68 and UDPGD mRNA in cells was detected, the character of liquid in subcutaneous synovial bursa was studied, and hyaluronic acid concentration of liquid was detected with ELISA. Secondly, a portion of peroneus longus tendon was taken from self-body of rabbit and it be placed into the artificial subcutaneous synovial bursa.

首先，在动物皮下手术埋置硅胶囊扩张器，经过不同时间充气和有规律的按摩刺激，使局部形成滑膜样包裹结构，从而构建人工皮下滑膜囊模型，通过大体观察、组织学结构、超微结构、免疫组化以及UDPGD功能性酶活性的检测、滑囊液HA浓度检测等指标，对滑膜囊结构和功能进行研究，探讨其形成的可能性。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
