Preliminary study of the resources of germ plasm of gramineous grass in Kirin Province, China.

标题 吉林省禾本科牧草种质资源的初步研究。

As De Groot observes (lsc, IV, 67):"Taoism being fundamentally a religion of the Cosmos and its subdivisions, old Chinese Cosmogony is its Theogony. It conceives the Universe as one large organism of powers and influences, a living machine, the core of which is the Great Ultimate Principle or T'ai-kih, comprising the two cosmic Breaths or Souls, known as the Yang and the Yin, of which, respectively, Heaven and Earth are the chief depositories. These two souls produce the four seasons, and the phenomena of Nature represented by the lineal figures called kwa".

作为德葛鲁特观察（ LSC种质，四， 67岁）说：&道家从根本上被一个宗教的宇宙及其分支机构，中国古老的宇宙起源是其theogony它构思宇宙作为一个大的有机体的权力和影响力，谋生机，其核心是伟大的终极原则，还是t'ai - kih ，组成两个宇宙呼吸或心灵，被称为阳和阴，其中，分别为，天与地都是行政托管机构，这两个灵魂产生四季节和现象的性质，代表了由直线数字所谓土瓜湾&。

The Samkhyas will say that the substance of each Guna comprises three characteristics (that is to say, the characteristics of the three Gunas), but that, through combination, they are so amalgamated as to make any distinction almost impossible; hence they appear as one.

再反过来说，种种质素与其所构成的法，既然是一而二、二而一，那它们应该是一而不是三。结论便是：你数论派要嘛否定大等的统合性，或否定贪瞋痴三德的三种性质。

The results showed that autote traploid rice might be effectively improved by ion beam bio-technique, from which the new germplasm with hereditable twin-embryo seedling could be selected.

结果表明，利用离子注入技术可以对同源四倍体水稻进行有效地改良，由此可以获得具有遗传变异特点的新种质，其双胚苗特性随着自交世代的推进而得到保持。

Information on the combining ability and heterotic patterns of maize germplasm is of great value to maize breeders.

研究玉米种质的遗传关系及其杂种优势模式对玉米育种者有着极为重要的指导意义。

The objectives of this study were: 1 to assess the breeding potential of maize populations including 2 of tropical origin and 7 of temperate origin;2 to find a new heterotic pattern among the 9 populations.

评估2个热带群体和7个温带群体的育种价值，并在这些群体之间寻找新的杂种优势模式，为利用这些种质提供有用的科学信息。

The new gemplasms of the sweet corn which were transferred and bred by our country were used as experimental materials to study the biochemical constitution,the heterotic rate and genetic control.

以我国自己转育成的甜玉米新种质为材料，研究甜玉米的生化成分、优势率和遗传控制。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
