Reaching een that leel of protection required 12 times the dose of antigen deliered by a typical flu shot , and required that the treatment be gien in two shots seeral weeks apart 而且，要达到这一水平的保护作用，还需要一个典型的流感疫苗的抗原剂量的12倍剂量，注射还分两次进行，第二次注射与首次注射间隔好几个星期。
Fourth , to make use of the method of progressive transmission . transmission by twice can effectively relieves the burden of network . fifth , through a post - processing according to the compress scheme , effect of reconstructed image is reinforced 第四，压缩数据传输时采用了一种特殊的渐进传输方法，根据用户需要分两次传输，可有效的降低对传输带宽的要求。
Comparison tests were made to the primary and secondory detonations and the same quantities of the same explosives , and found that both the surface rigidity and the depth of the induration layer have been improved obviously by the use of secondary detonation 同时对同种炸药相同药量分两次爆炸与一次爆炸的效果进行比较，发现采用二次爆炸要比一次爆炸无论表面硬度，还是硬化层深度都有明显改进。
Under the filtration irrigation , the water content could remained a fit range from 14 to 22 percent in the layer of 20 to 70 cm deep , however , the general irrigation could reduce the moisture utilization during the growing period of the maize . ( 4 ) filtration irrigation could well adjust the soil temperature so that the root system made a sufficient absorption of the moisture and mineral nutrinents 从土壤含水量测定分析看，在20 70cm土层，渗灌水分含量一直维持在玉米正常所需的14 22范围内，而漫灌分两次灌水，在每次灌水前一段时间水分含量要下降到14以下，出现水分胁迫，尤其影响到玉米的前期生长。
The refund of the surplus fund from the off - line subscription will be effected by two batches : on august 8 , 2008 , the co - sponsors ( lead underwriters ) will refund to the investors the subscription fund ( including invalid subscription fund ) refundable prior to the implementation of the clawback mechanism ; and on august 18 , 2006 , the co - sponsors ( lead underwriters ) will refund to the investors the subscription fund refundable after the implementation of the clawback mechanism , the amount of which depends on the situation of the implementation of the clawback mechanism 本次网下申购多余资金的退款将分两次进行： 2008年8月8日，联席保荐人(主承销商)将向投资者退还回拨机制实施前应退申购款(含无效申购款) ； 2008年8月18日，联席保荐人(主承销商)将向投资者退还回拨机制实施后应退申购款，该退款金额取决于回拨机制的实施情况。
In the study , the author changes the way of adding coagulation , which is called secondary coagulation technology to remove the organic substance of trace - contaminated original water . in fact , it is more effective . so - called secondary coagulation technology is that in the light of keeping the dosage as the routine one , add the coagulation for two times to the original water 本研究通过改变加药方式即二次凝聚工艺来去除微污染原水中的有机物获得了较好的效果，二次凝聚工艺即在保持与常规凝聚加药量相同的情况下，将凝聚剂分两次投加到原水中进行净化处理的工艺。
