From the point of view of geobotany, with the method of correlative factors of growth of plants, a countrywide theoretic ecological division was done for the introduction of Camptotheca acuminata and three kinds of areas of ecological preferent zone, ecological adaptive zone and ecological unadaptable zone were divided. With the theory of synecology, the characteristic on environment, constitution, life form spectrum, diversity, similarity of plots of communities were researched. Applying the method of species association, discrete distribution, indensity index, fractal geometry, etc. to research relations between the species of the communities, space distribution of Camptotheca acuminata, structure of age of Camptotheca acuminata, in different communities. Using the theories of autoecology, distibutons of seeds on land and growth of seedlings in vertical and horizontal directions, biomass of organ of Camptotheca acuminata were analyzed. On the opinions of conservation biology, the external and internal factors impressing Camptotheca acuminata were analyzed to research the mechanism of the endangered species, and with using of CTM Model, the future development direction of Camptotheca acuminata in different communities were forecasted, and. Standing on the position of resources ecology, discussing the regularity of camptothein in Camptotheca acuminata of different sites and seeding of different resources, also the the derive technics of camptothecin.

本文从地植物学的角度，运用植物生长相关因子法，对我国喜树资源的生态适宜区进行了划分，理论上确定了我国的喜树的引种栽培的最适生活区域、生态适宜区域和不适宜生活区域；从群落生态学的角度，对野生喜树所在的典型群落的群落环境、群落组成、群落生活型谱、群落的物种多样性特点、群落样地间相似性进行了研究；从种群生态学的角度，运用种间联结性、离散分布模型、聚集强度指数、分析几何等分析手段，对野生喜树所在典型群落间的种间关系、喜树的空间分布格局、年龄结构等进行了分析；从个体生态学的角度，对不同年龄组的喜树的种子的散落的垂直分布、水平分布、时间分布及种子发芽率和千里重等特点、不同种源的人工喜树苗期特点、喜树的高生长和茎生长特点、喜树的器官生物量特点进行了研究；从保护生物学的角度，对野生喜树的濒危的内部因素和外部因素进行了探讨，并运用CTM模型对不同群落中野生喜树的种群趋势进行了预测；从资源生态学的角度，对我国地理环境下喜树中喜树碱含量的地理分布规律、不同种源的喜树幼苗中喜树碱含量变化规律进行了研究，并对喜树碱的提取工艺进行了探讨。

"Because of its epochal scope, evolutionary biology is often caricatured as incompatible with controlled experimentation," says Losos, professor of organismic and evolutionary biology in Harvard's Faculty of Arts and Sciences and curator in herpetology at the Harvard Museum of Comparative Zoology.

"因为它的跨年代的时间尺度，进化生物学常常被讽刺为不适用于可以由控制性的实验来证明的学科。"

The overwhelming majority of soil physical, chemical and biological quality indicators increased incipiently and decreased subsequently with the increasing of dam land and terrace use years. They have been degenerate state and degradation will be lasted.

During my stay there,i was instructed in neurobiology.

呆在那里的那段时间，我学习神经生物学。

That shows time has a close relationship with matters which contain life. Learned from biology, we know the differences to distinguish living being and the rest is: the matter micro particle contained living being has the capability to regenerate; in other words, the special species matter micro particle of living being can regenerate 2 or 3 even more micro particle containing life. On the contrary, although the non living being micro particle changes continuously, the micro particle can not regenerate 2 or 3 even more counterparts.

这就说明了时间同含有生命现象的物质有着密切的关系，而生物和非生物区别又在何处；我们从生物学中知道：它们的区别是：含有生命现象的物质微粒能够有再生的变化能力，也就是说一个以本种形式存在的含有生命现象的物质微粒能够变成两个、三个以至更多个同样的含有生命现象的物质微粒，而非生物的物质微粒虽然是在不停的发生变化，非生物的物质微粒却不能变成两个、三个以至更多个不含有生命现象的物质微粒的。

Olney persuaded him to use the time to memorize biology terms. Another student posted a vocabulary list by the medicine cabinet.

他回忆起一位每天都参加训练的越野跑运动员，奥尔尼劝他利用训练的时间记忆生物学术语。

Evansi/HGPRT- could proliferate in the medium without HT and its pathogenicity to mice declined with the parasitemia and death of the inoculated mice to be delayed double than the control group.

生物学试验表明，HGPRT缺陷株在无HT的培养液中生长良好，对小鼠致病力有下隆的趋势，虫血症和小鼠死亡时间比对照组延长1倍多。

Efficacy: imitation of fish biology signals, using the majority of species increasingly sound, phototaxis, a specific sound, light, wave as an enticement factor, achieve far deeper waters of the call to lure fish to stimulate and focus on attracting fish swim to capture the workplace and improve fishing flats fishing operations the amount of time, with high economic and entertainment value.

功 效：仿鱼类生物学信号，利用多数鱼种的趋声、趋光性，以特定声、光、波作为引诱因素，实现对较远较深的水域鱼类的呼唤引诱，刺激并吸引鱼类集中游向捕捉工作地点，提高捕鱼者单位作业时间的捕渔量，具有极高的经济和娱乐价值。

Acousto-optic devices lure the fish, combined with the activities of fish characteristics and eating habits, through the imitation holographic fish biology signals, using the fish increasingly sound, phototaxis, a specific sound, light, wave as an enticement factor, achieve far deeper waters of the call to lure fish to stimulate and attract fish, swim to the phishing focus on the workplace and improve fishing anglers unit operating time, the amount of fish caught fishing with a high The economic value; this series of products, since the majority of sales have been very popular with fishermen, she was fishing people to like it.

诱鱼器是什么——美国声光诱鱼器，结合鱼的活动特点以及进食习性，通过模仿鱼类全息生物学信号，利用鱼的趋声、趋光性，以特定声、光、波作为引诱因素，实现对较远较深的水域鱼类的呼唤引诱，刺激并吸引鱼类集中游向捕钓工作地点，提高捕鱼钓鱼者单位作业时间的捕钓渔量，具有极高的经济价值；本系列产品，自销售以来一直很受广大钓友、捕鱼人的喜欢。
