There are many local taxis at the terminal; the price is about 200 RMB for a round-trip. It takes about half an hour to get to the entrance of Jinshanling; they will pick you up at the exit of Simatai. The time is a little longer on the way back to Miyun bus terminal from Simatai.

在终点有很多当地的出租车，价格一般是200元一个来回，把你送到金山岭，大概要半个小时，然后在司马台接你回密云公交车站，时间也差不多半个小时。

The concepts of the S-simplest form of a seminorm family P and the P-reflexive locally convex space are introduced. The seminorm family P and its every S-simplest form generate the same locally convex separated topology on X are proved.

引入半范数族P的S-最简形式和P-自反局部凸空间的概念，证明了半范数族P和它的每一个S-最简形式都生成X上相同的局部凸拓扑。

Locust bean gum (20% galactose) is more functional and more expensive than other galactomannan gums.

刺槐豆胶（半乳糖质量分数20%）与黄原胶的共混凝胶强度最大，也是价格最高的半乳甘露聚糖胶。

DPU at a concentration of as low as 10^(-7)mol/L retained the chlorophyll of Spirodela half-fronds under long-day conditions. From 10^(-5)~2×10^(-4)mol/L it prompted the synthesis of chlorophlly and the serine: glyoxylate aminotransferase activity, increased dry weight, and retarded the senescence of half-fronds.

在长日照条件下，10^(-7)mol/L的二苯脲对紫萍半叶状体就有保绿的作用，10^(-5)~2×10^(-4)mol/L的二苯脲还可以明显地促进叶绿素的合成和干重的增加，提高丝氨酸：乙醛酸转氨酶的活性，延缓半叶状体的衰老。

Finally, neglecting an immense literature that stretches from Ophelia to the Lorelei, let us note only the great half-anthropo-logical, half-cosmological analyses of Heinroth, which interpret madness as the manifestation in man of an obscure and aquatic element, a dark disorder, a moving chaos, the seed and death of all things, which opposes the mind's luminous and adult stability.

最后让我们跳过自奥非莉妮到罗蕾莱的浩瀚文学作品，仅仅提一下海因洛特引们的半人类学半宇宙学的精彩分析。他认为，疯癫是人身上晦暗的水质的表征。水质是一种晦暗的无序状态、一种流动的混，是一切事物的发端和归宿，是与明快和成熟稳定的精神相对立的。

Both LDPC codes and OFDM technology are studied in this paper. The working and the results obtained are summarized as follow:1. The definition of LDPC codes and its coding/decoding ideas are systematically summarized, a general algorithm of changing any parity-check matrix to lower triangular form, which is suitable for quick encoding, is given out, along with a girth checking algorithm. Absolutely random LDPC codes construction is improved, a new half random construction of LDPC codes with linear time coding and no 4-cycles is brought out.

系统地阐述了低密度校验码的定义及编译码原理，提出了一种将任何校验矩阵变换成适于快速编码的近似下三角形式的通用算法及一种围长检测算法，对完全随机的校验矩阵构造法进行了改进，提出了一类消除4环且可近似线性编码的校验矩阵半随机构造法，仿真表明，在高编码效率情况下，改进后的半随机构造法，其性能稍优于完全随机构造法，并可以线性时间编码，因此更适合实际应用。

And, slightly tongue in cheek, Dr Wilson quips that secularism is very maladaptive biologically.

威尔逊博士则半真半假地讽刺说：世俗化从生物学上来讲是非常不利的。

Results In 7 cases of odontoid process fracture, X-ray demonstrated 4 cases and CT demonstrated 5 cases, whereas the spiral CT reconstruction diagnosed 7 cases, which could display the displacement of fracture clearly. The X-ray and CT showed asymmetric space between left and right gaps of atlantoaxial joint in 6 cases, while spiral CT reconstruction showed normal and excluded the possibility of atlantoaxial dislocation. There was one case of lateral atlantoaxial joint dislocation, which was demonstrated by the spiral CT reconstruction clearly but not by the X-ray and CT scan. There were 3 cases of atlantoaxial congenital deformity (1 case of absence of both posterior arch of atlas and odontoid process and 2 cases of maldevelopment of the odontoid process), which were displayed clearly by spiral CT reconstruction, but misdiagnosed as odontoid process fracture and atlantoaxial subluxation by X-ray and CT scan.

结果 7例齿状突骨折中，X线显示4例，CT显示5例，CT重建确诊7例，且清楚显示骨折移位情况；6例X线、CT显示寰枢椎左右间隙不对称，通过CT重建排除寰枢关节半脱位；寰枢外侧关节脱位1例，CT重建可清楚显示，而X线片和CT平扫均未能显示；寰枢椎畸形3例，分别为齿状突、后弓缺如1例，齿状突发育不良2例，CT重建均能清楚显示，而X线、CT均误诊为齿状突骨折、寰枢椎半脱位。

Lastly , from a primitive rpp semigroup with zero , we built up a type A blocked Rees matrix semigroup and showed a semigroup S is a primitive rpp semigroup if and only if S is isomorphic toa type A blocked Rees matrix semigroup.

该结果的一个特例就是可消幺半群上的Rees矩阵半群。

The existence of the minimal and maximal fixed points for order preserving set-valued operators on semi-ordered sets and semi-ordered topological spaces was analyzed.

讨论了半序集和半序拓扑空间中保序集值算子的最小与最大不动点的存在性。

She gently rebuff ed him, but agreed that they could be friends
