B.the conversion of a solidC.when a solid is convertingD.a solid whose conversion 相关知识点: 试题来源: 解析 B 根据后面的is called sublimation可以看出,前面的部分是名词形式。A项出现了converts谓语,排除; C是从句形式,排除; D项中的whose后应该是一个完整的句子,而不应该是名词形式,排除。选B...
However, it remains unclear whether short, predominantly cellular RNA molecules can cause phase transitions to induce RNA foci. Herein, we demonstrated that short RNAs even with only two repeats can aggregate into a solid-like state via special RNA G-quadruplex structures. In human cells, these ...
Besides the classical ice–water phase change, the solid–liquid phase change exhibits many different behaviours: diffuse with respect to time and space phase change, phase change with voids and bubbles, phase change with different densities, dissipative phase change, irreversible phase change, phase ...
Complete (solid + liquid) phase diagrams are reported for the 10 mixtures: {(1 x) c-C mH 2 m + xC 6H 6}, m = 6, 7, 8; {(1 x)C mH 2 m+2 + xC 6H 6}, m = 8, 11, 12; {(1 x)C mH 2 m+2 + xc-C 6H 12}, m = 8, 12; and {(1 x)C mH 2 m+2 + x...
In contrast, the solid phase is an orderly array, or lattice, of atoms arranged in more or less close-packed rows and layers called a lattice. Atoms arranged in lattices constitute the solid bodies we call crystals. Iron in itsalpha phasetakes on the body-centered-cubic (bcc) lattice known...
The liquidus temperatures of the sodium vanadates were found to depend on the oxygen partial pressure for sodium oxide concentrations between 1.0 and 36 mol%. This effect was not observed for the ferric vanadate, chromic vanadate or magnesium vanadate systems. The solid–liquid phase equilibria for...
Solid phase regions. For an alloy, the liquidus temperature is that temperature at which a solid phase first forms under conditions of equilibrium cooling. Liquidus线。 在一张二进制相位图、分离液体和液体的那条线或者界限? 固体阶段地区。 为合金, liquidus温度是固体阶段最初版面在平衡冷却的情况下的那...
A new sample pretreatment method, solid-phase extraction combined with dispersive liquid–liquid microextraction (SPE-DLLME), was established for the sensitive determination of carbamates in environmental water samples. Three carbamates (carbofuran, carbaryl, and pirimicarb) were extracted from water sampl...
two microwave irradiation methods:(i) liquid-phase microwave irradiation(MWI) reduction of graphite oxide suspension dissolved in de-ionized water and N, N-dimethylformamide, respectively, and(ii) solid-phase MWI reduction of graphite oxide powder have been successfully carried out to reduce graphite ...
