Whether terrestrial life emerged on earth or through biological seeding from space or as the result of some intermediate scenario , the answer would be meaningful 无论地球上的生命是源于地球，或是来自太空的生物移民，还是介于两者之间的演绎结果，答案都别具意义。
In practice , the selected interval thickness is usually a compromise between the need for a thin interval to maximize the resolution and a thick interval to minimize the error 为保证最大分辨率必须选用薄层，为使误差最小却须选用厚层，实际上通常选择介于两者之间的最佳厚度。
To conform to the laws of a particular plane is a practical necessity ， and at this time the flying saucer craft simply cannot afford to stay betwixt and between for any indefinite period 遵循特殊层面的法则是实际的需要，这时，飞碟根本不能承受任何不确定期间的模棱两可的和介于两者之间的停留。
In usual situation it refers to a process including slight finance difficulty , the bankruptcy and all kinds of situation between them . in the empirical research , the listed companies always become the object of the researchers in our country 大多数学者将其定义为一个过程,既包括较轻微的财务困难,也包括极端的企业破产清算以及介于两者之间的各种情况。
We have carried out th / u dating on intercalated calcite samples . the results show that the capping flowstone layer is of an age of 94 ka , and the second one 220 ka . the fossil - bearing deposits which are bracketed by the two flowstone layers should be of an age between 94 and 220 ka 新生碳酸盐岩与骨化石的铀系测年结果表明：该地点覆盖含人牙化石堆积的表层钙板在约94ka以前开始形成，堆积叠压的钙板年代为约220ka ，人牙化石的年代应介于两者之间。
Based on this study the following conclusions are drawn : the responses of cable - stayed bridge under seismic excitations with spatial variations differ from those under uniform seismic excitations up to 30 % ; the responses obtained by considering travelling effect as well as incoherence effect are close to those obtained by only considering travelling effect ; travelling effect has more significant effect on the seismic responses of cable - stayed bridge than incoherence effect ; if r . m . s . ( root - mean - square ) of random seismic ground motions are equal , seismic responses are considerably greater for the case of soft soil than for the cases of firm soil or medium soil 研究结果表明：与一致地震激励相比，地震动的空间变化特性可以使斜拉桥的地震响应改变30 % ；同时考虑行波效应、部分相干效应时的地震响应接近于仅考虑行波效应时的地震响应；行波效应对斜拉桥地震响应的影响明显大于部分相干效应的影响；在加速度均方根相同的随机地震作用下，斜拉桥在软场地条件下的地震响应明显大于在硬场地条件下的响应，中等场地条件下的地震响应介于两者之间。
Abstract : the paper analyzes the wear resistance and anti - adhesion of 20 and 45 steel formed in austenitic ion - nitrocarburising and comparisons to the general ion - nitrocarburising . the experiment shows that austenitization - nitrocarburising can be carried out at 590 700 , its wear resistance and anti - adhesion is the best at 630 ， the worst at 660 and anti - adhesion is the best at 630 ， the worst at 660 and the mediate at 570 600 . with the help of raising processing temperature properly and speeding up the process the wear behavior can be improved 文摘:研究20钢、 45钢经奥氏体离子氮碳共渗后的耐磨性和抗咬合性，并与普通离子氮碳共渗后的作了比较，试验表明:在570 700范围内进行离子氮碳共渗后，其耐磨性和抗咬合性以630处理时为最佳， 660处理时最差，而570 600处理时则介于两者之间，通过适当提高共渗温度，再提高渗速，从而缩短共渗时间的同时，可以提高耐磨损性能。
The month average and the year average water vapor press in chongqing both show that : the water vapor press decreases with the increasing of sea level elevation ; the water vapor press values in north - west and middle hill areas are middle and high ; the water vapor press values in north - east and south - east mountain areas are relatively low . the sea level elevation in north - east and south - east mountain areas of chongqing is higher , especially the north - east mountains are more rugged than the north - west mountains , and the decreasing of water vapor press with the increasing of sea level elevation is more distinct , so the lowest value often appears in the north - east mountains not in the north - west mountains . the seasonal change of water vapor press in chongqing is also distinct : the values of water vapor press are low mostly in winter , and the high values are relatively less ; the values of water vapor press are middle and high mostly in summer , and the low values are relatively less , the values in spring and autumn are between them 重庆市全年各月月平均和年平均水汽压都表现出：随着海拔高度的增加，水汽压逐渐减小；西北部和中部的丘陵低山地区一般为水汽压的中高值区；东北部与东南部的山地地区的水汽压则相对较小重庆市东北东南山地地区海拔高度较高，尤其是东北山区的山地较东南山区的起伏更大，水汽压随海拔高度的减小更加明显，因此各月的最小值往往出现在东北山区而非东南山区重庆市水汽压的季节变化也很明显：冬季水汽压多为小值，大值较少；而夏季多为中、大值，小值较少；春秋季则介于两者之间。
According to the application background and the dismatch between single antenna and differential lna , an active balun is needed and has been designed . then we put forward a design scheme that does co - simulation of an active balun and a differential lna on one chip together . at 2 . 45ghz , this lna provides a forward gain of 28 . 931db with a noise figure of 2 . 485db , while drawing 19 . 1ma from a 1 . 8v supply 从本设计的应用背景出发,考虑到单端天线与差分lna之间的不匹配性,设计了一个介于两者之间的有源平衡转换电路? balun ( balance - unbalunce ) ,并提出了将这个balun电路与前面设计的差分lna作为一个整体进行了仿真的设计方案。
