图书分类法又叫图书分类词表，是按照图书的内容、形式、体裁和读者用途等，在一定的哲学思想指导下，运用知识分类的原理，采用逻辑方法，将所有学科的图书按其学科内容分成几大类，每一大类下分许多小类，每一小类下再分子小类。
中国图书分类基本分为马列主义毛邓思想、哲学、社会科学总论、政治、法律、军事、经济、文化、科学、教育、体育、语言、文字、文学、艺术、 历史、地理、自然科学总论、 数理科学和化学、天文学、地球科学、生物科学、医药、卫生、农业科学、工业技术、交通运输、航空、航天、环境科学、安全科学、综合性图书等这些类别。
1、哲学（缩写：Phil）（英语：Philosophy，希腊语：Φιλοσοφ?α）：是对基本和普遍之问题的研究。哲学分支有中国哲学、西方哲学、伦理学、宗教学、美学、逻辑学、心理学、科学技术哲学等。其按其词源有「爱智慧」之意。哲学是有严密逻辑系统的宇宙观，它研究宇宙的性质、宇宙内万事万物演化的总规律、人在宇宙中的位置等等一些很基本的问题。
2、政治：它指对社会治理的行为，亦指维护统治的行为来源:https://liuxinsheng.com/zhishi/202412-139.html。政治是各种团体进行集体决策的一个过程，尤指对于某一政治实体的统治，例如统治一个国家，亦指对于一国内外事务之监督与管制。
3、法律：是国家的产物，是统治阶级（泛指政治、经济、意识形态上占支配地位的阶级），为了实现统治并管理国家的目的，经过一定立法程序，所颁布的基本法律和普通法律。法律是统治阶级意志的体现，国家的统治工具来源:https://liuxinsheng.com/bkjj/202412-145.html。
4、文学：是一种语言艺术，是话语蕴藉中的审美意识形态。诗歌、散文、小说、剧本、寓言、童话等不同体裁，是文学的重要表现形式。文学以不同的形式即体裁，表现内心情感，再现一定时期和一定地域的社会生活。作为学科门类理解的文学，包括中国语言文学、外国语言文学及新闻传播学。
5、艺术：是宏观概念也可以是个体现象，是通过捕捉与挖掘、感受与分析、整合与运用（形体的组合过程、生物的生命过程、故事的发展过程）等方式对客观或主观对象进行感知、意识、思维、操作、表达等活动的过程，或是通过感受（看、听、嗅、触碰）得到的形式展示出来的阶段性结果。来源:https://drill-pipe.com/cshi/202501-273.html

暗银河系的发现及其科学意义
In addition to conventional galaxies, the universe contains very dim galaxies that until recently went unnoticed by astronomers. Possibly as numerous as conventional galaxies, these galaxies have the same general shape and even the same approximate number of stars as a common type of conventional galaxy, the spiral, but tend to be much larger. Because these galaxies ’mass is spread out over larger areas, they have far fewer stars per unit volume than do conventional galaxies. Apparently these low-surface-brightness galaxies, as they are called, take much longer than conventional galaxies to condense their primordial gas and convert it to stars—that is, they evolve much more slowly.
These galaxies may constitute an answer to the long-standing puzzle of the missing
baryonic mass in the universe. Baryons—subatomic particles亚原子粒子 that are generally protons or neutrons—are the source of stellar, and therefore galactic, luminosity, and so their numbers can be estimated based on how luminous galaxies are. However, the amount of helium in the universe, as measured by spectroscopy光谱学, suggests that there are far more baryons in the universe than estimates based on galactic luminosity indicate. Astronomers have long speculated that the missing baryonic mass might eventually
be discovered in intergalactic space星系际的空间 or as some large population of galaxies that are difficult to detect.

另类海豹哺乳方式与众不同来源:https://drill-pipe.com/cshi/202501-259.html
Until recently, zoologists believed that all species of phocids (true seals), a pinnipped family, use a different maternal strategy than do otariids (fur seals and
sea lions), another pinniped family. Mother otariids use a foraging strategy. They acquire moderate energy stores in the form of blubber before arriving at breeding sites and then fast for 5 to 11 days after birth. Throughout the rest of the lactation (milk production) period, which lasts from 4 months to 3 years depending on the species, mother otariids alternately forage at sea, where they replenish their fat stores, and nurse their young at breeding sites. Zoologists had assumed that females of all phocids species, by contrast,
use a fasting strategy in which mother phocids, having accumulated large energy
stores before they arrive at breeding sites, fast throughout the entire lactation period, which lasts from 4 to 50 days depending on the species. However, recent studies on来源:https://liuxinsheng.com/bkjj/202412-36.html
harbor seals, a phocids species, found that lactating females commenced foraging
approximately 6 days after giving birth and on average made 7 foraging trips during the remainder of their 24-day lactation period.
The maternal strategy evolved by harbor seals may have to do with their small size and the large proportion of their fat stores depleted in lactation. Harbor seals are small compared with other phocids species such as grey seals, all of which are known to fast for the entire lactation period. Studies show that mother seals of these species use respectively 84 percent, 58 percent, and 33 percent of their fat stores during lactation来源:https://www.drill-pipe.com/cshi/202501-459.html. By comparison, harbor seals use 80 percent of their fat stores in just the first 19 days of lactation, even though they occasionally feed during this period. Since such a large proportion of their fat stores is exhausted despite feeding, mother harbor seals clearly cannot support all of lactation using only energy stored before giving birth. Though smaller
than many other phocids, harbor seals are similar in size to most otariids. In addition,
there is already some evidence suggesting that the ringed seal, a phocids species that
is similar in size to the harbor seal, may also use a maternal foraging strategy.

pheromones是什么东东，是不是该划为odorant
There is no consensus among researchers regarding what qualifies a substance as a pheromone. While most agree on a basic definition of pheromones as chemicals released by one individual of a species which, when detected by another individual of the same species, elicit a specific behavioral or physiological response, some researchers also specify that the response to pheromones must be unconscious. In addition, the distinction
between pheromones and odorants—chemicals that are consciously detected as odors---can be blurry, and some researchers classify pheromones as atype of odorant. Evidence that pheromone responses may not involve conscious odor perception comes from the finding that in many species, pheromones are processed by the vomeronasal (or accessory olfactory) system, which uses a special structure in the nose, the vomeronasal organ (VNO),to receive chemical signals. The neural connections between the VNO and the brain are separate from those of the main olfactory system, whose processing of
odorants triggers sensations of smell. But while the VNO does process many animal
pheromone signals, not all animal pheromones work through the VNO. Conversely,
not all chemical signals transmitted via the VNO quality as pheromones来源:https://liuxinsheng.com/bkjj/202412-19.html. For example,来源:https://liuxinsheng.com/cshi/202501-200.html
garter snakes detect a chemical signal from earthworms—one of their favorite foods—via
the VNO, and they use this signal to track their prey.
