To investigate the kinetic isotope effect of Ti-Mo alloy hydrides, E of the deuterides is compared with that of the protides. When x=0.03, E of deuterium desorption is larger than that of protium desorption. When x=0.13 and 0.25, E of protium desorption is larger than that of deuterium desorption.

The slope estimate is the sample covariance between x and y divided by the sample variance of x.

斜率估计量等于样本中x和 y 的协方差除以x的方差。若x和 y 正相关则斜率为正，反之为负。

CP9 (X = 501 860, Y = 705 035); thence in a southwesterly direction to Corner Point No.

Eailroad Area的东北边的两个区域：第一个区域：从隅角点CP7（X = 501 810，Y == 705 010）起，边界线向东北方向延伸至隅角点CP8（X = 501 840，Y = 705 050）；从该点起向东南方向延伸至隅角点CP9（X = 501 860，Y = 705 035）；从该点起向西南方向延伸至隅角点CP10（X = 501 785， Y = 704 935）。

Work was also carried out. From numerous facts of ourprevious work, it might be seen that the stereoselectivity of aziridination viasulfonium ylides depends upon the sulfonium salts and C=X compounds. The moreactive the sulfonium ylide and C=X compound are, the more cis product is generated.Whereas, trans product will be major if the activity of the sulfonium ylide and C=Xcompound is low.

通过对以往工作的总结，我们发现，在经由硫叶立德途径的小环化反应中有一个经验规律：产物的立体选择性与所用的锍盐和C=X化合物有关，即锍盐和C=X化合物的活性增强，有利于形成顺式产物，反之，锍盐和C=X化合物的活性降低，有利于反式产物的形成。

To say that X educates or is educating Y is to say at least that X is fostering desirable and morally unobjectionable dispositions in Y by the use of methods that are also desirable and morally unobjectionable, or at least that X is cultivating dispositions in Y by certain methods.

我们说 X 教育或正在教育 Y ，意味着至少 X 正在使用无可争议的符合意愿的和道德的方法，在 Y 身上培养着无可争议的符合意愿的和道德的性状，或者至少 Y 用某种方法正在培养 Y 的性状。

The oxygen uptake activity using Triton X- 100 as substrate in a resting cell experiment demonstrated that one of the isolates, P nitroreducens TX1, showed the highest activity to transform Triton X-lOO, 528 nmole/min/g cell wet weight among the isolates. The generation time of strain TX1 was only 1.2 h by using 0.5% of Triton X-100 as sole carbon source in MSB medium. Furthermore, this strain could even grow on the Triton X-l00 at a concentration of IO%-2O%.

本研究藉由测定各菌株分解TritonX-100时的氧气消耗活性发现，编号82.10.6之菌株，经鉴定并命名为P.nitroreducens TX1，每克湿重的菌株具有528 nmole /min的高耗氧活性，尤其，该菌株以0.5%的TritonX-100培养时，世代时间仅为1.2小时，即使在10%-20%的Triton-X-100的培养环境中亦能维持生长，在过去相关研究中均尚未发表有此一特殊之生长特性。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
