Science Letters:Discovery of ultrahigh-T spinel-garnet granulite with pure CO_2 fluid inclusions from the Altay orogenic belt, NW China

We first report discovery of the spinel-garnet-orthopyroxene granulite with pure CO2 fluid inclusions from the Fuyun region of the late Paleozoic Altay orogenic belt in Central Asia, NW China. The rock is characterized by an assemblage of garnet, orthopyroxene, spinel, cordierite, biotite, plagioclase and quartz. Symplectites of orthopyroxene and spinel, and orthopyroxene and cordierite indicate decompression under UHT conditions. Mineral chemistry shows that the or-thopyroxenes have high XMg and A12O3 contents (up to 9.23 wt%). Biotites are enriched in TiO2 and XMg and are stable under granulite facies conditions. The garnet and quartz from the rock carry monophase fluid inclusions which show peak melting temperatures of around -56.7℃, indicating a pure CO2 species being presented during the ultrahigh-T metamorphism in the Altay orogenic belt. The inclusions homogenize into a liquid phase at temperatures around 15.3-23.8℃ translating into CO2 densities of the order of 0.86-0.88 g/cm3. Based on prelim

想起了"于文翠"

上世纪60年代有本连环画《于文翠》,说的是一个名叫于文翠的文工团员,演《白毛女》总不到位,每次排练到“喜儿哭爹”的场面时,不光哭不出来,还忍不住咯咯咯地笑个不停。

参透色空真境界,抛置乾坤再出家——郁达夫与禅宗文化关系论之二

郁达夫既逃禅又向往“爱情”,这曾令很多人感到困惑,但是仔细考察却不难发现,他在爱情中真正关注的并不是爱情本身,而是通过爱折射出的慰藉感和归宿感。爱的欢欣和美丽使他感动,但爱的易逝与多变也使他备感人生的空淡和无聊。当他在“爱、中参透“情禅”时,他的小说也一改早期的声泪俱下,痛器狂啸,变得澄净空明,平淡悠长,极富禅意。在中国现代小说史上,这是极其特殊的。

师范教育中的特殊教育与特殊教育学

教育不等于教育学。师范院校的教育专业不等于教育学专业。对于特殊教育来说 ,特殊教育学专业同样也不能代替聋校语文、聋校数学、聋校外语、聋校体育等面向具体学科的专业。学科特点与教育学相通的特殊教育学只是应该设置的面向特殊教育的专业中的一个部分。师范院校设置的有关特殊教育的专业中 ,除了应该包括特殊教育学专业之外 ,还应该包括其他面向基层特殊学校特定课程的各种专业。     

The development of the ability to recognize the meaning of iconic signs

Early developmental psychologists viewed iconic representation as cognitively less complex than other forms of symbolic thought. It is therefore surprising that iconic signs are not acquired more easily than arbitrary signs by young language learners. One explanation is that children younger than 3 years have difficulty interpreting iconicity. The current study assessed hearing children's ability to interpret the meaning of iconic signs. Sixty-six 2.5- to 5-year-olds who had no previous exposure to signs were required to match iconic signs to pictures of referents. Whereas few of the 2.5-year-olds recognized the meaning of the iconic signs consistently, more than half of the 3.0-year-olds and most of 3.5-year-olds performed above chance. Thus, the ability to recognize the meaning of iconic signs gradually develops during the preschool years. Implications of these findings for sign language development, receptive signed vocabulary tests, and the development of the ability to interpret iconic symbols are discussed.
