Examples are given to illustrate the conditional entropy maybe increased, so Shannon's definition of information is not absolutely correct.

论文摘要:从新的角度指出了香农信息论和信息定义的局限性,指出了它没有考虑信息的可靠性,完备性等特点,指出条件熵的命名不恰当,香农的"条件熵"应该称为加权平均条件熵,并且举例证明了条件熵可能增加,进而香农信息定义中的不确定性的减少也不是绝对的。

Limitations of Shannon's information theory and information definition are analyzed from new angles. It is pointed out that they didn't consider the reliability, completeness and other characteristics of information, and the naming of conditional entropy is not proper. The correct naming of Shannon's "conditional entropy" should be weighted average conditional entropy. Examples are given to illustrate the conditional entropy maybe increased, so Shannon's definition of information is not absolutely correct.

The calculation shows that the transition amplitudes display some damped oscillation with a period inversely proportional to the energy gap between the initial and final states and a damping time determined by the inter-molecular potential of the collision system.

对b与v对θ_的影响的分析表明,在物理上有意义的b和v的范围内,CO-He体系的θ_分布在30°~70°范围内,CO-HCl体系的θ_分布在93°~116°范围内,故不存在正负干涉抵消的问题,"平均效应"不严重。

Also because of the road turned to the bottom of the top players on the team at the top of the ramp, the rock loose the season still has the possibility of the Rolling Stones hit the players, Yakou the 50-100 m section of the rock surface is a monolithic block staggered zone, rock face an average of 6-7 meters high, 70-80 degrees slope is very smooth too laborious climb directly to undesirableGreat can not see well because of the snow line, and only a walk around the rock surface, in the cross section of rock surface from time to time is close to the ridge walk, the most recent is only one meter away from the cliff, and at the foot of ice or hard snow if the time is easy to slide down the ridge, more dangerous.

另外因为路线转向上方队员就在下方队员斜上方,岩石松动的季节还是有滚石击中队员的可能,垭口上50-100米路段,是整块整块的岩面交错的地带,岩面平均高6-7米,坡度70-80度,很光滑直接攀上太费力不可取,由于雪大看不出好的路线,只有绕着岩面走,在跨越岩面时有部分路段是贴着山脊走,最近的离悬崖仅一米,而且脚下如果结冰或者是硬雪时很容易滑下山脊,比较危险。

2The speed of creating random series used irrational fraction arithmetic was faster than that of multiplicative congruence arithmetic. The correlative value of random series almost was zero.(3) Regarding not harm the images quality as the premise, the speed of FM screening was heightened.

主要结论:利用所建立的条件半色调函数进行图像加网,操作简单、控制精确,使发生阶调不连续处的密度差平均减少到0.01275,明显改善了调幅加网印品的质量;(2)无理数取尾法产生随机数的速度快,数列间几乎没有相关性;(3)在不损失图像质量的前提下,提高了调频加网的输出速度。

According to the VESs analysis, the intrinsic brittleness of Fe〓Al is due to less lattice electrons, bondcomplex distribution heterogeneity, hydrogen-induced embrittlement, and the difficulty in recovery of the lattice symmetry, while various alloying elements have strengthening and toughening effects through altering the VES parameters.

运用固体与分子经验电子理论建立起Fe〓Al合金各相的价电子结构,在计算中,首次尝试利用TFD模型确定Fe〓Al的原子杂阶,针对不完全有序的B2-Fe〓Al提出"局部平均原子模型",对Fe〓Al的室温脆性从电子理论上进行了系统的阐述,认为较少的晶格电子、键络分布不均匀、氢致脆性和难以恢复晶体的对称性使Fe〓Al具有本质脆性,合金化元素可以在一定程度上改变价电子结构参数而改善强度和韧性。

The light scattering data were well described by the crossover model proposed by Anisimov and Sengers, and the effective critical exponentsγandυshowed nonmonotonic crossovers from the 3D-Ising values to the mean-field ones as the temperature departed from the critical point. The coexistence curves exhibited that the values of effective critical exponents for the order parameter of the refractive-index decreased as the distance from the critical point increased, however after the regular terms were subtracted, the nonmonotonic crossovers from Ising to mean-field critical behavior were exhibited. The influence of sodium bromide on the trend of the crossover was small.

静态光散射数据符合Sengers和Anismov等提出的临界跨接理论,关联长度和渗透压缩系数的有效临界指数存在非单调跨接,盐对于跨接程度的影响不明显;共存曲线研究发现,随着偏离临界温度,折射率的有效临界指数逐渐减小,但是当与共存曲线相关的正规项的影响被排除以后,体系表现出从3D-Ising到平均场行为的非单调跨接,盐对于跨接程度的影响不明显。

"In this trial, risperidone was safe and effective for the treatment of tantrums, aggression and self-injurious behaviors in children with autistic disorder," write Lawrence Scahill and colleagues from the Research Units on Pediatric Psychopharmacology Autism Network.

参加此次试验的101位儿童(82位男孩,19位女孩)的平均年龄为8.8+/-2.7岁,采用risperidone0.5-3.5 mg/日,持续8周治疗的患者中,兴奋性得分降低了56.9%,而安慰剂组降低了14.1%p 作者指出的研究限制包括,观察时间不够长,不能确认risperidone的最小有效剂量,以及研究的注意力集中在特定的行为问题上,而不是孤独症的核心症状。

The development of the regional forestry industry was uneven.(2)The geographical distribution of China's forest industry and Forest resources was uneven during 1998-2007.The degree of the uneven geographical distribution of the primary industry of China's forestry industry and forest resources was de

我国林业第一产业与森林资源在地理分布上的不均衡程度逐年降低;而我国林业产业总产值、第二产业与第三产业与森林资源在地理分布上的不均衡程度则先在1998-2003年间逐年升高,然后再缓慢下降;(3)1998-2007年间,全国只有浙江、福建、西藏、吉林、黑龙江的林业产业结构对其林业产业增长的贡献始终高于全国平均水平,其他省份的林业产业结构还需调整。

SRL was slightly higher of white maize and black maize in Cd and pyrene contaminated soil than that in uncontaminated soil. SRA, ARD and SRV of white maize and black maize decreased in Cd and pyrene contaminated soil compared to control, but the difference was not significant between the two treatments.

与未污染相比,Cd+芘复合污染下白玉米和黑玉米的根长稍有增长,根表面积、根平均直径和根体积减小,但两处理间差异不显著。
