A permeance value obtained under one set of test conditions may not indicate the value under a different set of conditions.

在一组试验条件下得到的水蒸气透过系数值不一定能表示试样在其它不同的试验条件下的水蒸气透过系数值。

The results of calculation and measurements have been demonstrated by the experimental researches on photosensitivity and grating performance of chalcogenide fiber.

在详细了解和分析硫系玻璃材料性质的基础上，对硫系光纤的基本特性、特殊工艺、光纤的基本实验方法进行了理论和实验研究。

Located in the adjacent area of Shanxi, Gansu and Sichuan provinces,the Yangshan gold deposit is a superlarge-scale gold deposit in Devonian epimetamorphosed phyllite or limestone,which is found by gold geological party of CAPF in recent years.

甘肃文县的阳山金矿床是武警黄金部队近年来在陕甘川交界地带发现的一个产于泥盆系浅变质岩系的特大型金矿床，勘查后求得储量已达227 t之巨。

Phytogeography which study flora geography and vegetation geography research the relation between the plant distribution and space and time. It has great meaning for studying plant distribution , flora evolve , protection and utilization of plant resources, vegetation evolve etc..

植物地理学研究植物区系地理和植被地理即植物分布与空间及时间的关系，对于研究植物的分布、区系演化、植物资源保护和利用、植被演替等均有重大的意义。

The main clime features included ataxia, hypopsia, axanthocyanopsia and retinal pigmental degeneration. Alleles from 7 to 9 repeats were seen in the other 4 healthy members. GAG repeats from 6 to 21 were found in other 126 SCA patients, 71 family members and 60 healthy controls.

该家系内表型正常的4位成员SCA7等位基因CAG重复数目为7~9，另126例临床表现为SCA的患者、71名表型正常的家系成员及60名健康对照者SCA7等位基因内CAG三核苷酸重复数为6~21。

The author offers numerous examples of mistakes he has discovered as evidence: green bean as mung bean, linden as pipal, date as jujube, oak as acorn tree, and more comical1y, killer whale as manslaugter whale, to name just a few examples of inaccurate translation.

举例来说，green bean是「四季豆」，但常被误解为「绿豆」：linden系「椴树」，但在台湾却被当作「菩提」； oak系「栎树」但被译成「橡树」，几使「栎树」真名不彰；olive与「中国橄榄」，date与「枣子」都是完全不同的植物，却因误译而被以为是相同的东西。

Starting from piperonal, the initial total synthesis of CET involved BischlerNapieralski reaction, 3, 2-sigmatropic rearrangement, unusual Nazarov-type electrocyclization, and autoxidative dehydrogenation of desmethylcephalotaxine to desmethylcephalotaxinone etc.

第一条路线我们以胡椒醛为起始原料，经Bischler-Napieralski反应，[3，2]-σ重排，6-6环系到7-5环系的还原重排，Nazarov氧化环化；碱性条件下脱甲基三尖杉碱到脱甲基三尖杉酮碱的氧化脱氢等20步反应，完成了三尖杉碱的全合成。

Three methods for establishment of female lines from pistillate plants in castor(Ricinus communis L.)were compared in this report :Staminate flowers are induced by high daily temperature in NES-pistillate p lant.

比较了三种由雌性单株建立蓖麻雌性系方法：(1)利用环境高温处理NES型雌性单株诱导雄花建立雌性系，是比较成熟的方法，但对日均温要求较高。

The QTLs controlling the three traits had the same direction on additive effects and dominant effects. And these traits showed bimodal or discontinuous distributions in respective NILs. These results imply that the same gene might control the three traits simultaneously (i.e.; the gene pleiotropism).

两个近等基因系的QTL分析结果表明，3个性状都是由一个QTL或紧密连锁的QTL控制，而且加性效应和显性效应的方向均相同；同时3个性状在各自的近等基因系中呈现典型的双峰分布或不连续分布，这些结果暗示3个性状可能是一因多效的结果。

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％。
