Theorem 2.3.3 Let R be a reduced left morphic ring, then R is a right PS-ring.

定理2.3.3：设R是约化的左morphic环，则R是右PS-环。

If ring eRe and (1 - e)R(1 - e) are both left morphic rings, then R is also a left morphic ring.

如果eRe和(1-e)R(1-e)都是左morphic环，则R也是左morphic环。

Flow rate was 1.0 ml/min. Results: The linear ranges of icariin and naringin were 30~150 μg/ml(r=0.9997) and 10~50 μg/ml(r=0.9995), respectively.

结果：淫羊藿苷和柚皮苷的线性范围分别为30~150 μg/ml (r=0.9997)和10~50 μg/ml (r=0.9995)，平均回收率分别为100.04%和100.23%。

1 After comparison of sum fusion and optimal fusion, sum fusion was selected as the fusion scheme for local test statistics. For the distributed CFAR detection based on the above three local statistics and sum fusion: CA-R-SUM and OS-R-SUM, CA-S- SUM and OS-S-SUM, Max-OS and Min-OS, Max-CA and Min-CA, their analytic expressions of detection performance were derived for and in nonhomogenous background.

2.1 通过求和融合与最优融合的性能对比，确定了以求和融合做为对局部检测统计量的融合方案；推导出了基于上述三种新的局部检测统计量和求和融合的分布式 CFAR 检测方案： CA-R-SUM 和 OS-R-SUM 、 CA-S-SUM 和 OS-S-SUM 以及 Max-OS 和 Min-OS 、 Max-CA 和 Min-CA 在、条件下在非均匀杂波背景中检测性能的解析表达式。

In New York he roomed with O'Brien while they attended the Academy of Dramatic Arts. In 1923 they both got nonspeaking parts as robots in "R.U.R".

在纽约的戏剧艺术学院学习时他仍和老友欧布莱恩共住一室，1923年两人同时获得了影片《R.U.R》中两个没有台词的机器人角色。

Large condensate gas pools are developed in the Ordovician and Carboniferous in the Lunnan low salient. Geochemical study shows that the Ro of gas condensate in these gas pools is in the range of 0.8% 1.0%(far below the threshold of R o＝1.3％ for thermal cracking), and the condensate gas is overmature dry gas (with R o＞2.0%). Moreover, the crude oil and dry gas in the study area were charged in different stages, indicating that the genesis of the condensate gas was not thermal cracking.

轮南低凸起奥陶系及石炭系发育大规模的凝析气藏，地球化学的研究结果表明，这些凝析气藏中凝析油 Rc 在0.8%~1.0％（远低于热裂解成因 R o＝1.3％的门限），凝析气为过成熟干气（回归 R o＞2.0％）；同时，区内原油与干气的充注期相异，表明轮南地区的凝析气藏并非热裂解成因的产物。

Two photo-chromatic organic materials for CD-R/CD-RW are found. One photochromatic organic material for Blue-light DVD-R/DVD-RW is found.

发现了两种适合CD-R／CD-RW的有机光致变色光盘材料和一种可用于红光和蓝光DVD-R／DVD-RW的有机光致变色光盘材料。

Scanning tunneling microscope was used to investigate the in vitro assembly of R-phycoerythrin from the marine red alga Polysiphonia urceolata. The results showed that R-PE molecules assembled together by disc-to-disc while absorbing on HOPG surface, which just looked like the rods in the phycobilisomes.

将海洋红藻R 藻红蛋白吸附到刚揭开的高定向石墨表面上，然后用扫描隧道显微镜在纳米尺度上进行直接观察，发现纯化的R 藻红蛋白在体外自然聚集时，能够&面对面&的聚集在一起，形成非常规则的类似藻胆体的杆状结构。

Six-stage counter-current extraction experiments were carried with two different solvent to raffinate ratio i.e. E/R=4, 8. A better result was found with E/R=4, that gave 90% in oil recovery and 8~9% oil concentration in extract.

本研究建立多级逆向萃取的数学模式，并分别以两种溶剂与固体比(E/R=4，8)进行实验，验证数学模式的实验结果显示E/R=4效果较佳，六级的逆向萃取，萃取收率达90%且萃取液浓度可维持8~9%。

如果试图分派\r\n一个已声明却未定义的程序， Perl 将重分派到 AUTOSUBDEF 或 AUTOMETHDEF \r\n来定义这个程序。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
