A series of internal documents from the late 1970s and early 1980s shows that BAT at least thought about applying this knowledge to cigarette design. A research report from 1979 puts it thus: There are three major design features which can be used either individuallyorin combination to manipulate delivery levels; filtration, paper permeability, and filter－tip ventilation. A conference paper from 1983 says, The challenge would be to reduce the mainstream nicotine determined by standard smoking－machine measurement while increasing the amount that would actually be absorbed by the smoker. Another conference paper, from 1984, says:（5）We should strive to achieve this effect without appearing to have a cigarette that cheats the league table. Ideally it should appear to be no different from a normal cigarette...

英美公司上世纪70年代末、80年代初的一系列内部文献表明，该公司至少曾考虑过将这一知识用于卷烟设计。1979年的一份研究报告上这样说道：可分别或联合应用与设计有关的三个要素，即过滤、烟卷包装纸的通透性以及过滤嘴的通气效果，来控制焦油和尼古丁的释放水平。1983年一份会议论文也提到，关键在于，要在提高吸烟者尼古丁实际吸收量的同时，减少可被标准检测方法测定到的含量。1984年另一份会议论文说：我们应当努力达到这一效果并能在检测中蒙混过关。

It is the summation which the society and economy relation reflect essentially. The manpower capital property right have three common characters: exclusiveness、 resolvability、business and four special characters: the first one, the owner have not impartibility ownership and control right to the manpower capital himself. The second one, manpower capital can reflect in the different way of material capital when the property right deformity; the third one, manpower capital's employment and investment course are in-phase, the fourth one, the effective yardstick and mechanism of measuring manpower capital are absence.

在此基础上，概括出人力资本产权排他性、可分解性、可交易性的一般特征以及它的四个特殊特征：一是所有者对其自身的人力资本并不具有不可分离的所有权和控制权；二是当发生产权残缺时人力资本可以以迥然于物质资本的方式回应，通过关闭人力资本达到效用享有的均衡；三是人力资本的使用和投资过程是同步合一的；四是缺乏有效计量人力资本的尺度和机制。

The results show that a little amount of heteropolymolybdovanadophosphate can remarkably speed the degradation, the best conditions of the oxidative degradation of chitosan with hydrogen peroxide catalized by heteropolymolybdovanadophosphate in homogeneous condition are as follows: the ratio of catalyst and chitosan is 1 to 10, concentration of hydrogen peroxide is 0.15%, the temperature is 80℃, reaction time is 2h. 0.2g chitosan was degraded under the best condition and the molecular weight by viscometry was degraded from 1460000 to 7812. then water-soluble chitosan was obtained by this method; The heterogeneous method is a high efficient way, the best condition of this method are as follows: the ratio of catalyst and chitosan is 2 to 100, the volume of 30% hydrogen peroxide is about 3mL, the temperature is 90℃, reaction time is 5min～30min.

研究结果表明，适量磷钼钒的存在可显著加速壳聚糖的降解，磷钼钒催化过氧化氢均相氧化降解壳聚糖的适宜反应条件是：催化剂与壳聚糖的质量比为1∶10、过氧化氢百分浓度为0.15％、反应温度为80℃、反应时间为2h，在此条件下对0.2g溶解在100 mL 0.5％稀醋酸中的壳聚糖进行降解，可使壳聚糖的粘均分子量由原来的146万下降到七千多(7812)，成为水溶性低分子量壳聚糖，从而达到应用的要求；在异相条件下以磷钼钒为催化剂催化过氧化氢氧化降解壳聚糖是一种高效快速的方法，此法降解壳聚糖的最佳反应条件是：催化剂与壳聚糖的质量比为2∶100；30％过氧化氢的用量为3mL左右；反应温度为90℃、反应时间为5min～30min。

The effects of 20~100 mg/L MS-222,Tricaine Methanesulphonat,were tested at water temperature 15~25 ℃ on two species of sturgeons,Acipenser sinensis and A.schrenckii.

以20~100 mg/L的MS-222在水温15~25℃条件下对中华鲟和施氏鲟(A.schrenckii)的麻醉效果进行试验，中华鲟或施氏鲟分别达到不同程度的麻醉状态甚至出现死亡。30~40 mg/L的MS-222具有较好的麻醉效果，鱼的活动量明显下降，可保持镇静并维持身体平衡和正常体位，麻醉48 h后，在清水中数分钟内可恢复正常游动状态，适合于长途运输。50~100 mg/L的MS-222对中华鲟和施氏鲟具有较强的麻醉作用，适合于进行短时间的操作，如捉拿、称重、测量、外科手术、体外标记等。

There were lesser and fewer in commercial species and its numbers in the cover net, and the sum of Nemipterus virgatus , Saurida tumbil , Upeneus bensasi , Trachinocephalus myops comprised 95.4% in number and 86.0% in weight of sample catch in the cover net,respectively. The high percentage of juvenile commercial species that were undersized in the codend showed 30.3 mm square mesh codend had more serious damage to most juvenile commercial species, approaching or exceeding 50% in percentage of juvenile species which body length is smaller than fishable size- Trichiurus haumela, Priacanthus tayenus , Navodon tessellatus, Argyrosomus argentatus, Nemipterus bathybius and so on, even exceeding 90% in percentage of juvenile Sepia spp, Loligo spp and Parastromateus niger. In particular, 50% selection lengths ( L 0.5) caught Saurida tumbil and Nemipterus virgatus were smaller than their minimum fishable size.

结果表明，这种规格的方目网囊平均尾数逃逸率为29.76%，平均重量逃逸率为8.46%；出现在套网中的经济种类少、数量少，条尾绯鲤、金线鱼、多齿蛇鲻、大头狗母鱼4种鱼的尾数和重量分别占套网抽样渔获的95.4%和86.0%；网囊中带鱼、长尾大眼鲷、黄鳍马面鲀、白姑鱼、深水金线鱼等鱼种的体长小于可捕标准的个体尾数比例均超过或接近50%，枪乌贼、乌贼、乌鲳等幼鱼尾数比例达90%以上，多齿蛇鲻和金线鱼50%选择体长均未达到最低可捕标准，表明该种规格网囊对多数经济种类幼体的损害比较严重。

No doubt,"men" are the subjects of education, which call for diverse teaching styles. On the other hand, historical heros as canonic stereotypes are worthy of being topics in class, so as to initiate students' independent, systematic thinking and judgment.

「人」是教育的主体，教学的方法很多，在人史洪中可为典范、可为借镜的人物少，以人物做为教学的题材，古今映照、激发同心，构建脉络性思维，「进而建人的主体性」，「中国代人物概」的课程是达到「全人教育」目标的重要一环。

In this paper, we have proposed a flexible encryption blocks selection buyer-seller watermarking protocol integrated the RSA asymmetric encryption system and homomorphism mechanism to protect the ownership of digital contents and fit real life. And consider the secondhand transaction in the real life. We also propose a buyer-reseller watermarking protocol based on the flexible encrypt blocks selection buyer-seller watermarking protocol to offer a solution of secondhand transaction. In our scheme, it's more light data transport requirement than other schemes. All roles in protocol will benefit by their participation. Our scheme can overcome various of the known attacks and security problems in the buyer-seller watermark protocol, such as buyer's right problem, unbinding problem, piracy tracing problem, conspiracy problem, buyer's participation in the dispute resolution problem, man-in-the-middle attack problem and anonymous problem. Furthermore, the seller and arbiter can verify the buyer's watermark without decrypting it in our scheme.
