ตัวอย่าง fossilize

• The dark contrast of the fossilized cell walls suggests that a light element (low atomic number), perhaps carbon, is still present.

• However, this technique only provides an external morphological description of putative fossilized cells and is incapable of distinguishing between abiotic fossils of similar morphologies.

• These methods, especially in relation to the theory of frames, have imported a new interest into a subject which was in danger of becoming fossilized.

• The resulting structures (stromatolites) often undergo only moderate diagenesis and fossilize with characteristic biofabrics.

• In the case of fossilized, older, adult learners this may be true.

• It is quite impossible, then, to give a principled reason why one part of the cluster would fossilize and another would not.

• The mat-forming microorganisms were healthy when fossilized (by silicification) and showed no morphological signs of stress.

• The prediction, then, is that successful resetting is impossible, and the interlanguage grammar of every learner will fossilize at the nontargetlike value.

• Close morphological resemblance to contemporaneous microorganisms and other fossilized microorganisms further support that interpretation.

• In such a situation the tendency for it to fossilize into ritualized officialese is increased because the countervailing influences of less formal varieties of the language are not so strong.

• Also, it cannot be ruled out that this first planktonic stage did not possess a calcified exoskeleton, which may explain why it has not been fossilized.

• We cannot unequivocally eliminate an ancient origin because the chemical signatures are similar to those of the fossil substrates, raising the possibility that they were fossilized together.

• The length of the present test section is not sufficient to reach the fossilized state and the data can support no firm conclusions with respect to a fully fossilized turbulence.

• It will be important below that the phonological environment in which the ex-process occurred (its 'structural description') is also fossilized, as the 'exceptions' to a change.

• When the conditions of acquisition are less advantageous, the learner language is likely to fossilize at a lower level of proficiency, which is often the basic variety.
