Hangzhou Bay Bridge is the dream of many years Ningpo, Hangzhou Bay is the world's three-tidal bay, the biggest feature is a flood, streaming urgency, while the southern coast has a very wide beach, the beach there are more than nine kilometers, in the Land under some natural gas, the construction of a bridge in this place, in the past were very rare, and uniqueness lies in the special geographical environment, the difficulty of his decision, he is quite a high cost, so that the Hangzhou Bay Bridge The greatest feature is that under these conditions to build a bridge, how to overcome difficulties.

杭州湾跨海大桥是宁波人多年的梦想，杭州湾是世界三大强潮海湾，最大的特点就是一个潮大，流急，另外有一个南岸非常宽的滩涂，这个滩涂有九公里多，在滩涂底下还有一些天然气，在这个地方建桥，在以往是很少的，特殊性就是在于特殊的地理环境，决定了他的难度，他的成本也是相当的高，所以说杭州湾跨海大桥最大的特点就是在这种条件下要建设一座大桥，如何去克服困难。

Chitosan had been modified by polyacrylate sodium, glularaldehyde, and NaBH4, respectively, which afforded three kinds modified chitosan: polyacrylate sodium modified chitosan (CIS- PA4) chitosan bead and pentamethylene diamido crosslinked chitosan bead (CTSB- G- Hy). The adsorption properties of CTS-CTSB and CTSB-G-Hy were studied by L25(56) orthogonal experimental design. They show high adsorption activities for Pb2+ in solution. The highest removal efficiency of Pb2+ for CTS-PA4, CTSB and CTSB-G-Hy is 94%, 96% and 93%, respectively. The results showed the adsorption property of CTSB is the highest. The CTSB- G- Hy has good mechanical property, acid-resistance and alkali-resistance.

A frame image of a video frequency sequence is read into a postpositional memory zone, and staring position and size information of a tracked object is obtained in the frame, then distribution statistical information of a target signature is extracted to build a gauss mixed model as an object template, a mean vector and a covariance matrix in gauss mixed distribution are used to describe the position and the size of the object, then the next frame image of the video frequency sequence is read into the postpositional memory zone. In a new frame video frequency image, a parameter estimation method is used to obtain object gauss mized model parameters in the current frame in iterative computation and find candidate template similar to the object template, and the final model parameters obtained in iteration are used to update the tracking window for realizing self-adaption of the tracked window.

将视频序列的一帧图像读入缓存区，获得该帧中被跟踪目标的初始位置和尺寸信息，然后提取目标特征的分布统计信息建立高斯混合模型作为目标模板，用高斯混合分布的均值向量和协方差矩阵描述目标的位置和尺寸，再将视频序列下一帧图像读入缓存区，在新一帧视频图像中利用参数估计方法迭代计算当前帧中目标高斯混合模型参数找到与目标模板最相似的候选模板，利用迭代得到的最终模型参数更新跟踪窗口实现跟踪窗宽的自适应。

In details, the strongest inhabitation to the shoot growth was observed when neutral soluble fractionates were supplied. The shoot biomass with neutral soluble fractionates added was decreased by 10.52% over the blank control, resulting in obvious increase of root: shoot ratio. It suggests that the root exudates would be self-poisonous. Besides, both acid and alkaline soluble fractionates exhibited the trend to increase the stem height and it is necessary to exploit the reasons.

在培养液中，分别加入分组的烤烟根系分泌物，均显著降低根系对NO_3~-、H_2PO_4~-、K~+离子的吸收和根系活力，推测根系分泌物中产生抑制作用的物质可作用在相当宽的pH范围；其中，碱溶性组分对H_2PO_4~-、酸溶性组分对K~+、中性组分对NO_3的吸收和根系活力的抑制作用较强，推测在烤烟根系分泌物中，可能存在多种抑制烤烟生K和养分吸收的化学物质；另外，抑制作用随着根系分泌物浓度的增加而增强。

Using this method, wide dimming range can be achieved with narrow frequency range and constant DC link voltage. And the lamp current keeps perfect sine wave all the time, which means low lamp current crest factor is obtained. Its validity is verified by simulation and experiment.

本章最后提出了一种基于T型滤波器的新型的调光方法，采用此方法可以在保持逆变器直流母线电压和开关占空比不变的情况下，只需很窄的频率范围就能达到非常宽的调光范围，而且在整个调光范围内灯电流都基本上是完美的正弦波，这就意味着可以始终保持很低的灯电流波峰因数，仿真和实验结果充分验证了它的优点。

马上枪术比赛参加的人也很多，他提供了玩家在现实专中去挑战他们朋友的机会，手里拿着泡漠的矛，参加比赛的人需要努力的让自己在攻击别人的时候保持平衡，他们是在一个3尺宽的平台上进行的。

Reflecting on that achievement involves first of all acknowledging that we do think and experience things in those ways. Those are the 'premisses' from which transcendental reflection on the necessary conditions of our thinking in those ways begins. Accepting such premisses means ascribing those thoughts and experiences to human beings. We can then reflect in a broadly Kantian spirit on the conditions of our making such ascriptions—on what must be so, how we must be able to think, and what we must be able to do, in order to think of anyone as possessing such thoughts and experiences.

从那些对我们的思进行先验反思来说是前设的东西开始，接受这些前设意味着把那些思或经验&归&给人，我们因此能在更宽的意义上反思导致这些&归&——是什么使得必须如此，我们如何必须能够思，我们必须能做的是什么——的条件，从而为了考察任何拥有这样的思或经验的人的情况。

The Namibian tourism industry was just cutting its teeth, and community-based conservation approaches were almost non-existent.

保护区的边界几乎是不存在的，当地的农民和居住者定居在仅仅30公里宽的狭长的尸骨海滩公园上，人们和狮子间的冲突非常严重，1990年前以知的带项圈的狮子都已经被射杀，这种现象被看成是纳米比亚海岸狮灭绝的征兆。
