The source,existing form and equilibrium of carbonic acid in natural water are presented in this article,which points out that alkalinity is determined by double indicator that indicates purply at the first terminal point,while at the second terminal point should use methyl red-bromocresol green mixed indicator.

介绍了天然水体中碳酸的来源、存在形式及平衡关系；指出用&双指示剂&法测定水中碱度的第一终点应显粉紫色，第二终点宜采用甲基红-溴甲酚绿混合指示剂；测定游离二氧化碳要用双样测定并严格控制滴定终点；各种碳酸的含量可与pH值、硬度的测定结果进行校核。

All the LOH on 〓 and 〓 was observed in invasive ductal carcino- ma, carcinoma simplex, medulary carcinoma and scirrhous carcino- ma, no deletions at these sites were observed in any invasive lobular carcinoma and others. These results imply an etiological difference.P53 gene is a hot point gene in the occurrence and development of breast, cancer. PCR-SSCP analysis was performed to detect P53 gene point mutation in the region between exon 5 and 8, 5 of 12 (41. 6%) stage I breast cancer patients contain mutation of P53, 3 of 5 patients were accompanied by 〓 deletion. These results suggested that point mutation and allelic loss of P53 gene are two vi- tal genetic events in earlier stage of breast tumorigenesis.

我们还发现，〓和〓位点LOH均分布在乳腺浸润性导管癌、单纯癌、髓样癌及硬癌中，在浸润性小叶癌和某些特殊类型乳腺癌中全部为LOH阴性，上述位点LOH可能与某些组织学类型乳腺癌的发生有关。P53基因是乳腺癌形成过程中的一个热点基因，本研究对12例Ⅰ期乳腺癌组织标本中P53基因热点区域第5、6、7、8外显子点突变进行了测定，发现41.6％（5／12）的病人有P53基因一个或多个点突变，其中3例同时伴有〓位点LOH，表明P53基因点突变和等位基因缺失是发生在乳腺癌形成早期的一个重要遗传学事件。

Methods 15 SD rats, 8 males and 7 females, were set to receive radiant-heat stimulus at 5 different measure points-right and left footplates, tail root, proximal trichotomous point of the tail and distal trichotomous point of the tail to measure their escape response latencies in a constant ambient temperature (21-23℃) at 3 different time points-9:00, 15:00 and 20:00 in 7 consecutive days.

15只SD大鼠，雌7只，雄8只，在恒定的环境温度下，连续7d分别在每天的9：00、15：00和20：00采用热辐射刺激大鼠双足底、鼠尾根、鼠尾近侧3分点和鼠尾远侧3分点共5个不同的刺激点，测定每个刺激点对刺激反应的潜伏期。

Life, then, is really a dream, and we human beings are like travelers floating down the eternal river of time, embarking at a certain point and disembarking again at another point in order to make room for others waiting below the river to come abroad.

生活如梦，我们就像是在永恒时间之河中漂流的旅客，在某一点上船，然后为了给岸边的其他旅客留足够的位置，又在某一点下船。

Life, then, is really a dream,and we human beings are like travelers floating down the eternal river of time, embarking at a certain point and disembarking again at another point in order to make room for others waiting below the river to come abroad.

人生真是一场梦，人类活像一个旅客，乘在船上，沿着永恒的时间之河驶去。在某一地方上船，在另一个地方上岸，好让其他河边等候上船的旅客。

The stereo image pair is acquired by a pair of calibrated cameras. Global disparity of foot is estimated at first. After the image pair is preprocessed automatically, using non-contact information-collecting technique and phase-correlation method, which is based on complex wavelet, surface matching with sub-pixel accuracy in the frequency domain is carried out. By taking order matching constraint, continuity constraint and correlation constraint together, 3D point cloud of foot is reconstructed and 3D model of foot is built by mosaicking point cloud at various angles automatically. After normalization, high-order moments are compared, which is useful for the subsequent shoe last design.

运用已标定的双目照相机拍摄立体图像对，进行足部整体视差估计；在对立体图像对进行自动预处理后，采用非接触式的信息采集技术，运用基于复小波的相位相关技术对足部表面进行亚像素级小区域频域匹配，考虑顺序匹配约束、连续性约束和相关性约束条件，重建足部密集三维点云信息，并自动拼接不同角度点云生成相应的足部三维模型；对其归一化后，提取其高阶矩向量进行比对，为后续的三维鞋楦设计提供必要信息。

Now pull out a "neutral dart" of the task, we can still去凑热闹trumpet, and that profit, of course, the most lucrative robbery argue openly that we are not robbed, and took advantage of people in the black spots in shuttle, in the starting point for others to see you when class is not very conspicuous一百六七十foreigners generally will not kill you, the opportunity to gain the upper hand at the starting point is when the car up to a maximum of staring at a car radio with light arrows do not line with bow and arrow skills that will be found and shot while walking a little before he was taken to machine shop was robbed, and good luck today, I get a click on the 60D.

现在又出了一个拉&中立镖&的任务，我们这些小号也还是可以去凑热闹的，那利润最丰厚的当然是抢劫咯，公然抢劫那我们是不行的，趁着人多在黑点中穿梭，在起点时别人看你才一百六七十级不是很显眼一般外国人是不会杀你的，下手的机会就是在起点时，人最多车最多盯着一个车用弓箭轻射千万不要用弓箭系的技能那会被人发觉的，边走边射，嘿嘿等他还没拉到机械工厂那时就被劫了，今天本人运气好一下就抢了个60D。

Aiming at feature point based image registration, we suggest the concepts of broad sense feature point and narrow sense feature point.

针对基于特征点的图像配准，本文提出了一种基于广义特征点的图像自动配准方法。

We cannt get result on how to change course and speed to make collision avoidance, this can help little on collision avoidance decision.The article aims at the default on Radar simulator and implements the standard result on Radar simulator by making use of MCU.the main production is below:First, we calculate how to chang course and speed on the destine point by MCU. We get the new course and new speed on the destine point,we get the point to resume original course and speed, we get the distance and azimuth to resume original course and speed on given course and speed, the six essential: DCPA, TCPA, distance, azimuth,real speed and real course.

本论文针对当前雷达模拟器标绘训练中的不足，实现了利用单片机进行雷达模拟器标绘标准值的计算，主要成果有以下方面：首先，利用单片机计算得到了在预定点改变航向和改变航速的计算，求得预定点改向的新航向C_N和预定点变速的新速度V_N，恢复原航向和原航速的时机点的计算；在给定避碰的新航向、航速的条件下，计算出恢复原航向／航速的时机点H的距离R_H和方位θ_H；目标船的六要素，即DCPA、TCPA、距离R、方位θ、真航速V_T和真航向C_T。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
