查询词典 matter

The observations of dark and bright matter wave solitons,the study of matter wave solitons have been one of the hot issues in the fields of both low-temperature physics and condensed matter physics due to their potential application.

玻色-爱因斯坦凝聚中的暗，亮物质波孤子的成功观测及它们的潜在的应用前景，也使玻色-爱因斯坦凝聚中的物质波孤子成为了当前低温物理和凝聚态物理研究领域的研究热点之一。

The above multiple changes will produce 2 kinds of waves, Matter waves and mechanical waves that spread at the same time. Because the electromagnetic wave is a matter wave, it is the medium. Since the multiple exchanges of the electrons state can be regarded as electrical vibration, and the vibrated electrons have magnetic fields and electrical fields at the same time, the electromagnetic wave will be produced. Then, because the electron itself is a matter micro particle, it can produce mechanical waves which can propagate outside with electrical magnetic waves.

这种状态改变的多次往复，就会产生两种波，一种物质波，即电磁波；一种机械波，并且这种机械波是以同次产生的电磁波为媒质进行传播的，，这是因为本种状态的多次往复，可以看作是一种电子振动，振动的电子同时具有磁场和电场，所以能够产生电磁波，又因为电子本身是一个物质微粒所以他能够产生机械波，并且是横波，并随电磁波进行向外传播。

It appears to you that there is living matter and nonliving matter, leading to such questions as: How does nonliving matter become living?

在你们看来存在着有生命的事物和没有生命的事物，而导致产生这样的问题：没有生命的事物是如何变成有生命的？

"Dark matter : Nonluminous matter not directly detectable by astronomers, hypothesized to exist because the mass of the visible matter in the universe cannot account for observed gravitational effects."

暗物质：不发光的物质，天文学家无法直接发现，由于宇宙可见物质的质量无法解释观测到的重力效应而假设其存在。

"Dark matter : Nonluminous matter not directly detectable by astronomer s, hypothesized to exist because the mass of the visible matter in the universe cannot account for observed gravitational effects."

暗物质：不发光的物质，天文学家无法直接发现，由于宇宙可见物质的质量无法解释观测到的重力效应而假设其存在。

"Dark matter : Nonluminous matter not directly detectable by astronomers, hypothesized to exist because the mass of the visible matter in the universe cannot account for observe d gravitational effects."

暗物质：不发光的物质，天文学家无法直接发现，由于宇宙可见物质的质量无法解释观测到的重力效应而假设其存在。

Negative matter is a hypothetical form of matter whose mass is opposite in sign to normal positive matter.

负物质是一种假象的物质形式，其质量在标示上与正常的正质量相反。

With hydroponic culture, we studied the effects of Zn(superscript 2+) on dry matter and zinc accumulation in wheat seedlings using Chang 5864 as the experimental material. In this paper, Zn(superscript 2+) concentration in cultivating solution was 30 and 60 mgL^(-1), respectively, and 0 mgL^(-1) Zn was set as control. Seedling root and plumule were gathered every day from 4 d to 13 d after cultivation. We measured dry matter weight, and analyzed zinc concentration by atomic absorption spectrometry. The results showed that the dry matter accumulation in seedling root and plumule were all significantly improved under Zn treatment.

为了探明Zn在小麦植株中的吸收、分配和积累规律，以小麦品种长5864为供试材料，来用室内水培方法，于培养4~13d后取幼芽和幼根，用原子吸收分光光度计法测定样品中Zn的含量，研究了不同Zn(上标 2+)供应水平（0、30、60mgL^(-1)，分别用Zn0、Zn30、Zn60表示）对小麦幼苗干物质积累及幼苗Zn含量和积累的影响，分析了小麦幼苗中Zn的积累规律。

Gray matter damage was assessed on the basis of the number of normal neurons in the ventral horn. White matter damage was assessed on the basis of the extent of vacuolation and amyloid precursor protein immunoreactivity in the ventral and ventrolateral white matter.

根据腹角内正常神经元的数目评估灰质损伤程度，而白质损伤则根据空泡形成的程度以及腹内和腹外侧白质的淀粉样前质蛋白免疫原性来评估。

The United Kingdom has pledged to provide technical assistance to the peacekeeping effort in Darfur, including airlifting supplies and equipment to assist the African peacekeepers.

英国承诺为达佛的維和努力提供技术帮助，包括提供非洲的維和部队空运补給和裝备。

Results: The level of ET-1mRNA in placental villus was significantly higher in pre-eclamptic women than that in control group.
