But," says Von Braun,"I decided that if I had to know about math to learn about space travel and rocketry, then I'd have to learn math.

他就是那样做的。

In normal situation of teaching, math self-controlling ability will increase together with the increase of age and math knowledge.

在正常教学条件下，中学生数学学科自我监控能力的发展呈现年龄阶段性； 3。

On account of the traffic flow with the high complexity and randomicity, we could adopt fuzzy theory and fuzzy control technology without setting up an accurate math model, which can avoid the unideal control effect, brought by inaccurate math model, and also can adapt the real-time control. Therefore, this paper applies the fuzzy theory and fuzzy control technology to research and discuss traffic control.

因为，交叉路口交通流的运行具有高度复杂性和随机性的特点，采用模糊理论和模糊控制技术，可以不需要建立精确的数学模型，这样既可以避免由于被控对象数学模型建立的不准确而导致控制效果不理想，又能够适应交叉路口的实时控制要求。

In the studying of image segmentation, six crucial technologies havebeen developed successfully. 1 In one dimension histogram of original DRimage of luggage, there remain maximum-value wave crest havingapproximately stationary position, and the first minimum to the left of thewave crest performs excellently to be used to get rid of background of DRimage. 2 Open operation, one type of math morphology, is the right idea toerase luggage disturbance in DR image and at the same time, can be retaininteresting region appropriately. 3 After open operation, there are only a few minimums on image histogram, one of which can be to segment image furtherand achieves satisfying result. 4 Method of histogram analyzing and that oferosion performs well in the re-segmentation of conglutinative region in DRimage. 5 Method of image distance switch can ensure Luggage CT sectionautomatically obtained to have rich suspicious region information. 6 Todecompose structure element of math morphology is a way to save a great dealrunning time for automatically discerning interesting regions algorithm,apparently improving implementation efficiency.

在对图像可疑区域分割研究中，主要开发成功以下几项关键技术：1发现原始箱包DR图像的一维直方图中，均具有位置相对稳定的最大值波峰，以波峰左边第一个极小值为分割阈值，去除DR图像背景，效果非常好。2运用数学形态学中的开运算能够非常有效地去除箱子的干扰，同时能够比较好地保留可疑区域。3发现开运算后的DR图像直方图只有若干个极小值点的特点，其中用最大值波峰左边的第二个极小值点进一步分割DR图像，能够更有效地提取箱包中的可疑区域。4运用直方图分析法和腐蚀法，对粘连区域实行再分割，效果较好。5运用距离变换法，能确保自动设定的箱包CT截面包含丰富的可疑区域信息。6运用形态学结构元素分解技术，大幅度减少可疑区域的自动判别算法运行时间，提高算法软件执行效率。

Math Game Using Different levels of Skil - This program was designed to help people to improve their basic math skills (addition, subtraction, multiplication,division).

这个程序旨在帮助人们提高他们基本的数学技能（加法，减法，乘法，除法）。

In order to make the sense of self-efficiency widespreadly applied to math study, we expect, from the angle of psychology of mathematic education, to study the effects of the sense of self-efficacy in students math study and then formulate certain teaching concepts and principles, so as to guide the practical teaching of this subject as well as of others.

研究者认为，加强学生自我感觉意识是强化学生的反思意识不可缺少的一部分。在教学中，发现影响自我效能感形成和发展的主要因素，进而将提高数学学习的自我效能感深入到教学活动中去，是当今数学教学改革所面临的一个重要课题。

I failed in the first examination and got either 3 or 5 marks on math - You won't be surprised at my poor math score if I told you that I didn't finish junior high school.

我的第一次考试不合格，数学只考了不是3分就是5分。如果我告诉你我初中没毕业你就不会对我数学考这么差而感到惊讶了。

I failed in the first examination and got either 3 or 5 marks on math - You won't be surprised at my poor math score if I told you that I didn't finish junior high school.

我的第一次考试不合格，数学只考了不是3分就是5分。

The result shows that there were some difficulties on the design of the math activities when we planed the activities. However, difficulties can still be solved by finding topics in math coerces, discussing students' experiences and learning process, adapting daily life context and group cooperative designs.

研究结果发现，在设计数学活动的考量上，从准备规划到拟定方案，虽然面临一些困难，但可以从数学课程中寻找主题、探讨学生过去的经验与学习、采用生活化情境与团队共同设计。

I love math as math delights my life.

我爱数学因为它点亮了我的生活。
