A circle is the set of all points in a plane equidistant from a fixed point called the center point. We can derive the equation directly from the distance formula. If we place the center point on the origin point, the equation of a circle with center point (0, 0) and radius r is x^2 + y^2 =r^2。 相似文献

This study explores the role folk tales of deception might play in assisting the child's development of a theory of mind. Four three- and four-year-olds read and reread “The Brave Little Tailor” with their parents. The results suggest that rereading a folk tale of deception sets a framework for social interactions supporting the development of the child's understanding of mental representation. The deceptions of the story elicit discussions—of thoughts and feelings and their relation to intentions and actions—that change over the course of successive readings as the child shows increasing comprehension of the deceptions of the story and decreasing need of parental support. Parent-child pairs differ in how they structure their interactions and gender of parent and of child appears to affect how frequently and explicitly connections are drawn between actions, beliefs, and reality. Reading a familiar story with a new person allows the child to assume a more active “expert” role. 相似文献

In order to help the selection and training of teachers for kindergartens, a scale for diagnosis of the special psychological predispositions needed for kindergarten teachers has been developed. It consists of 130 items derived from a personality test and an ability test.
By the use of stratified sampling strategy, 660 teachers from different kindergartens in Beijing were chosen to form a sample group in its development. The result of the test was displayed in the form of T-score and percentile respectively. After several times of practice, its reliability and validity have been verified. 相似文献

A smile costs nothing,but gives much. It enriches those who receive, without making poorer those who give. It takes but a moment, but the memory of it sometimes lasts forever. None is so rich or mighty that he can get along without it , and none is so poor but that he can be made rich by it . A smile creates happiness in the home. fosters good will in business, and is the countersign of friend- ship. It brings rest to the weary,cheer to the discouraged, sunshine to the sad, and is nature's be… 相似文献

The ultimate bending moment and maximal shear stress of a bulk carrier with two structural forms (single hull and double hull/ are calculated separately by using the combined moment which is determined by stochastic process. Then the assessment of reliability is carried out. The results indicate that by introducing the double-hull structure, the shear stress of side can be decreased to half of that of the primary structure( 50.7% i. but the effect on longitudinal strength is not obvious. Finally, the effects of different double-side skin widths on ultimate bending moment and the maximal shear stress are investigated, followed by proposals of the selection of the double-side skin width. 相似文献

The sustainable water system (SWS) was interpreted based on green residential zone associated codes issued by P.R. China and some other countries, and ecological principles. Its constitution, designing and engineering, and economic and environmental benefits were illustrated with a case of a campus construction project. The SWS incorporates divided nature drainage systems, grey water treatment and reuse technologies, rainwater decentralized collection and purification technologies, and water quality safeguard techniques for reclaimed water reused for landscaping. Application of the SWS is expected to gain remarkable economic and environmental benefits by reducing both the demand for municipal water supply and sewage discharge. 相似文献
