There have also been two less catastrophic pandemics. The so-called "Asian" flu of 1957 caused between one and four million deaths, while 1968's "Hong Kong" flu - with about half the estimated deadliness of the Asian flu - caused one to two million deaths.

还有两次比那一次稍微好一点的大流行。1957年所谓的"亚洲的"流感导致了一百万到四百万的死亡而1968年的"香港"流感,估计大概"亚洲的"流感致死一半,引起了一百万到两百万的死亡。

Result In the first 4 d of experiment, the corrected mortalities of spore suspensions with various concn. of P. cicadae APC20 to P. xylostella were lower than 50%, but on the 7 th day, that of spore suspension with concn. of 3.0×10^8 spores/ml reached 85.11% and the insect corpses was bestrewed in the mycelium and spore powder of P. cicadae, indicating that APC20 showed stronger parasitic lethality to P.

结果]药后第1~4天,蝉拟青霉APC20各个浓度的孢子悬浮液对小菜蛾的校正死亡率均低于50%,而第7天,浓度为3.0×10^8个/ml的孢子悬浮液对小菜蛾的校正死亡率达85.11%,并且虫尸布满蝉拟青霉的菌丝体和孢子粉,说明APC20对小菜蛾呈现较强的寄生致死性。

The most suitable range of temperature is 25~30℃ and lethal temperature is 56℃ for hypha growth, the most suitable temperature is 25℃ for produce more conidiospore and lethal temperature is 56℃ for conidiospore. Within the pH range of 3~11 the hypha could grow and produce conidiospore. The optimum pH is 5~7 for hypha growth and 3, 9, 10 for produce more conidiospore. The range of glucose concentration is 2%~8% for hypha growth, the most suitable glucose concentration is 2% for hypha growth and produce more conidiospore. The effect of illumination on Bipolaris cynodontis was significance to the growth hypha and spore numbers. The whole light is advantage of hypha growth, but could not produce conidiospore. Alternation of light and darkness for 12 hours is advantage of hypha growth, as well as produce conidiospore.

菌丝最佳生长温度是25~30℃之间,在25℃时最利于产孢,菌丝生长和分生孢子的致死温度是56℃;该菌在pH 3~11范围内均能生长,产生分生孢子,菌丝生长的最适pH 5~7,产孢量最大的pH是3,9,10;糖浓度在2%~8%菌丝能生长,在糖浓度为2%时菌丝生长最好,产孢量最高;光照对病原菌的菌丝生长和产孢有明显影响,在全光照的条件下有利于菌丝的生长,但不会产孢,黑暗12h光照12h既利于菌丝生长又利于产孢,而全黑暗的条件下不利于菌丝生长和产孢。

In this study, for the complicated distribution of dose rate in time and space, considering the repair of the sub-death cells, the radionuclide decay law and exponential proliferation of clonogenic cells, the dose-response relationship is built based on the known linear-quadratic model, and the concept of tumor control probability is introduced into the therapy method. Furthermore, the concepts about "curable stage" and "critical time point" and the methods calculating the amount of radionuclide injected into tumor in clinical are proposed.

本课题针对这一方法中靶区复杂的剂量率时-空分布特点,以公认的"线性-二次模型"理论为基础,同时考虑亚致死性细胞修复、核素衰变规律和克隆原性细胞指数增殖,建立了适合这一治疗方法的具有时-空分布特点的剂量效应关系,并进一步将肿瘤控制概率的概念引入这一方法中,提出了"治愈期"及"临界时间点"的概念以及由此指导临床确定药物注射剂量的方法。

The contents of valine and leucine of the nematode are obvious higher than that of others in different kinds of amino acid of the nematode. The analysis of irritant factors playing a important role on the production of predacious organs showed that live nematode larva or its lytic solution can cause the production of predacious organs of the strain A1, but the latter produced less than the former .The live larva of the third stage produced more predacious organs than one of the first and the second stage , so the number of predacious organs that are produced by the live larva of first and the second the stage are less than the live larva of the third stage .

刺激捕食器产生的因素在线虫体来说:活的线虫幼虫和其裂解液可以刺激捕食线虫性真菌—少孢节丛孢菌菌株产生捕食线虫性结构——捕食器;但后者刺激产生的捕食器数量较少;有活力的第三期幼虫与第一、二期幼虫相比较,可以刺激菌株产生较多的捕食器;但少孢节丛孢菌对第一、二期幼虫作用速度快;与第三期幼虫相比,第一、二期幼虫易被捕获致死。

Because Rwanda is the most densely populated country in the world, the 1.3-million-square meters now cleared of land mines can be turned into much needed farming land as well as eliminating the threat of death and maiming.

由于卢旺达是世界上人口最密集的地区,清除了地雷的130万平方米的土地可以转为急需的农业用地,同时也根除了致死或致残的威胁。暂无词汇

Expression analysis with RT-PCR revealed that PcLGBP gene was exclusively expressed in hepatopancreas and the expression could be up-regulated by heat-killed Listonella anguillarum. The binding specificity of PcLGBP to ligand were subsequently examined by recombinant expression of the cDNA fragment encoding its mature peptide in Escherichia coli BL21 (DE3) and ELISA approach.

为分析PcLGBP基因的功能,通过半定量RT-PCR方法研究了其在组织中的分布,并用荧光定量PCR技术分析了其对细菌刺激的响应,结果表明PcLGBP基因是肝胰腺特异表达的基因,能响应热致死鳗弧菌刺激而增强表达,说明PcLGBP基因可能参与螯虾的细菌防御反应。
