物质

Statement that any particle of matter in the universe attracts any other with a force that is proportional to the product of their masses (m1 and m2) and inversely proportional to the square of the distance between them.

宇宙中任何物质粒子吸引任何其它物质粒子的力的大小与它们质量(m1和m2)的乘积成正比，与它们之间的距离成反比的一种叙述。

Thenard(1811), the discoverer of hydrogen peroxide, expected that its degradation in living tissue is performed by a special substance, which Schonbein (1863) identified as a certain kind of 'ferment'. Loew (1901) was the first who named this H2O2-degrading enzyme catalase, but it took further 22 years until Warburg (1923) demonstrated that the active center of catalase contains iron, as concluded from the characteristic inhibition with cyanide.

过氧化氢的发现者Thenard ，希望活体组织中过氧化氢的降解是由一种特殊物质引起的，Schonbein定义这种特殊物质为某种酵种，Loew是第一个定义为过氧化氢降解酶，22年后Warburg 证明过氧化氢酶的活性中心含有Fe，正如从已知氰化物的特性得到结论。1927年，WIeland提出了一个简单的细胞过中氧化氢酶的解释。

We must not fall into the error of certain theosophical circles, and imagine the etheric and sentient bodies as consisting simply of finer substances than are present in the physical body.

我们不能陷入通神论的误区，将"生命体"和"情绪体"想象成是由优于"物质体"要素的物质构成的。

1St, foreword main point: A, about Earth's internal heat circulation as well as successional variation process three important times: Birth time, lifeless time, until has the life time; B, the earth interior stone fruits archery target thermonuclear reaction, causes the earth interior material convection and the Earth revolve production as well as terrestrial magnetic field production three between relations; C, also has in has the life time, the vital activity to the entire internal heat circulation influence as well as to the earth's atmosphere influence; D, has the life time, in the stratum the coal and the petroleum, the natural gas and so on the fixed energy storage which as a result of energies and so on zoology and botany absorption transformation sunlight forms, to Earth internal heat circulation influence as well as with earth's crust each kind of movement relation, such as: The plate movement, the volcanic earthquake, the orogenesis, the Earth moves the fierce degree the periodic phenomenon and so on.

前言要点： A 、关于地球的内热循环以及演变过程的三个重要时期：诞生时期，无生命时期，直至有生命时期； B 、地球内部核物质的热核反应，引起的地球内部物质对流与地球旋转的产生以及地球磁场的产生三者之间的关系； C 、还有在有生命时期，生命活动对整个内热循环的影响以及对地球大气的影响； D 、有生命时期，地层中煤与石油、天然气等由于动植物吸收转化太阳光等能量而形成的固定能量存储，对地球内热循环的影响以及与地壳各种运动的联系，诸如：板块运动，火山地震，造山运动，地球活动剧烈程度的周期性现象等。

Moreover, the effects of the molar ratios of the reagents on the yield are examined. The best molar ratios are a 2.0 molar equivalence of thionyl chloride and a 3.0 molar equivalence of paminophenol to retinoic acid, and the total yield is 80.7%.

此外，研究了反应试剂的摩尔比对反应收率的影响，最佳摩尔比为二氯亚砜和对氨基苯酚物质的量分别是维甲酸物质的量的2倍和3倍，总收率为80.7%。

Its principle is to use the acid standard solution or the alkali standard solution to titrate the opposite acid-base material, by which the content of measured material is calculated according to standard solution's consumption.

其原理是用酸标准溶液或碱标准溶液来滴定具有相反酸碱性的物质，根据标准溶液的消耗量来计算被测物质的含量。

Using materials such as earth, water, wood, metal, cotton, paper, stone and mirrors, the juxtaposition of natural and man-made materials -- left as far as possible in an unaltered state -- allowed materiality to speak for itself, almost entirely free of artistic intervention.

他们采用了诸如泥土、水、木材、金属、棉布、纸张、石头和镜片的物质材料，将这些自然和人工的材料并置在一起——尽可能地让它们保留在一种未经改变的状态中——这样物质本身得以言说自身，几乎完全排除了人为的干预。

The joint toxicity was evaluated by different methods, including toxicity unit,additive index, similarity parameter and mixtures toxicity index. The results show that the binary joint effects of phenol and toluol mixed with SDS are synergistic, while the binary joint effect of SDS and nitrobenzene is antagonistic. The environment risk of some compounds will be enhanced because of the joint of SDS.

研究结果表明： 4种不同的评价方法对SDS与取代芳烃苯酚、甲苯和硝基苯的联合效应评价结果具有较好的一致性，即SDS与苯酚、甲苯的二元混合体系的毒性表现为不同程度的协同作用，而与硝基苯则表现为弱拮抗作用；对环境存在风险性的阴离子表面活性剂SDS，当与一些有毒有害物质共存时会增加该类物质的环境风险性。

However, topdressing two weeks before heading increased the rates of dry matter production and accumulation during grain filling.

但在孕穗期（抽穗前2周）增施氮肥可增加灌浆期的单株干物质生产量和抽穗后干物质积累率。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
