查询词典 negative catalyst

The reasons for both positive and negative nominations in sociometry were collected and categorized into nine social-related traits. They were positive and negative competence, positive and negative interacting behaviors, positive and negative self-related characteristics, positive and negative appearance, and misbehavior. Three subscales of the SSSL provided self-reported traits of social skills, social relations, and social anxiety.

Therelationship of the amount of catalyst and the ee% of product was seen to be negative nonlin-ear. Catalyst 3 was used in the enantioselective addition of diethylzinc to aromatic aldehydesand gave good results. The configuration of products was determined by the configuration ofthe catalysts' chiral carbon linked with hydroxy group. Using β- amino alcohols bearing only one chiral center as catalysts for the enantiose-lective addition were studied. D-N, N-dialkyl-2-amino butanol gave poor catalytic effect be-cause of their structure. The configuration of the product is the same as the catalyst. Anotherkind of β- amino alcohols - phenylglycine derivatives and valine derivatives have chiralcenter on the carbon linked with amino group. Catalyzed by-phenylglycine derivatives 6,7, 9, 10, the reactions gave satisfied results. The optical yields exceeded 80%.

在探讨了含有两个手性中心的β-氨基醇之后，选择了只有一个手性中心的β-氨基醇，一是手性中心为连羟基的手性碳原子：D-N，N-二烷基-2-氨基丁醇；二是手性中心为连氨基的手性碳原子：D-苯基甘氨酸衍生物和L-缬氨酸衍生物。D-2-氨基丁醇的催化效果不太好，这与其结构的空间位阻较小有关系，反应产物与连羟基手性碳构型一致；由苯基甘氨酸和缬氨酸出发合成五种β-氨基醇6-10，研究了不同ee％的-6作用下的二乙基锌-苯甲醛加成反应，发现该催化剂具有不对称放大效应；-7，9，lO的催化效果也比较令人满意，光学产率80％以上，所得产物构型与催化剂构型一致。

Therefore, in this article,we first discussed the compound negative binomial, it able to simultaneously fitthe claim size and the claim number. At the same time, we studied the sum of themutually independent compound negative binomial and the sum of the mutuallyindependent compound negative binomial with discount factor and the sum of themaximal compound negative binomial; Next, for the claim data to be better fitted, this article has establishedthe superposition distributed model about the weighted average of the discreterandom and has discussed the estimation method of the parameters of thesuperposition distribution; Once more, we in detail elaborated the NCD which based on the claim numberand the NCD which based on the claim size and the claim number. Besides, weestablished an applied NCD model which also based on the claim size and the claimnumber; At last, we introduced the rewards and punishment coefficient of automobiletravel region into the applied NCD model, availably consummated the present NCD.

As a whole, the rocks from diorite enclaves, through quartz-diorite, granodiorite to monzonitic granite, have the feature of REE slightly increasing, Eu from weakly positive transits to negative anomaly, but the diorite enclaves which has Eu negative anomaly. Besides, the Ba, Nb, Ta, P and Ti all show negative anomaly, and have positive anomalies of K and Th, simultaneously, there exists Sr positive anomaly in some rocks. Along with the increasing of the SiO〓, the P and Ti have negative anomaly, Th and K positive anomaly are obvious.

张广才岭中生代不同时期的花岗岩具有相同的Sr、Nd同位素特征，均具有高ε〓值、低，值的突出特点，ε〓值集中在-2～+4之间，〓值主要集中在0.703～0.706之间。

Besides, I also find that firms report negative earnings for fiscal year, which have less current and future earnings response coefficient than report positive earnings, and firms report negative cash flows from operating for fiscal year, which have less current cash flow response coefficient than report positive cash flows. Indicating that firms report negative earnings or cash flow, because losses are more transitory and which stock prices less information but which future cash flow response coefficient more than report positive cash flows. Inference of this study because cash flow have substance effect, so when firms have negative cash flows investor more care about it, which have more cash flow response coefficient, and further find while distinguishing the degree of sophisiticated investor, investor the sophisiticated degree proportion is higher. Because they know information of the earnings, firms have more degree of shareholder sophistication for fiscal year, which have more current and future earnings response coefficient than which have less.

此外，本文也发现报导损失之公司，其当期及未来盈余反应系数较报导利润之公司低，以及公司报导营业活动之现金流量为负时其当期营业活动之现金流量反应系数低於报导营业活动之现金流量为正之公司，显示公司报导损失或营业活动之现金流量为负时，因为通常都是暂时性的故其股票报酬的资讯性较低，不过其未来营业活动之现金流量反应系数高於报导营业活动之现金流量为正之公司，本研究推论因为现金流量是有实质的效果，所以当现金流量为负值时投资人应该会比较关注，所以其反应系数较高，而进一步发现当区分投资人之精明程度时，投资人精明程度比重较高，因其会辨识盈余资讯而认为公司进行损益平稳化会增加其资讯内涵，故当期及未来盈余反应系数相较於投资人精明程度较低者高。

2B8a was weakly reactive to neutrophils (23.72%) and negative for T cells, NK, DC, RBC and Plt. The antibody reacted to all 3 marrow CD34+ cells with an average positive rate of 39.33% while it was negative for G-CSF-mobilized CD34+ peripheral blood stem/progenitor cells (PBSC, 1.25%). Cell line analysis showed that the antibody notably reacted to three out of 4 cell lines (Raji, SMS-SB, Nalm-6 and Nall-1) with the positive rates of 98.78%, 98.61%, 94.93% respectively and weakly to one of them with 5.68% in B lineage cell lines and monoblastic cell line (U937, 67.78%) while it was only weakly positive or negative for other myeloid leukemia cell lines including Meg01 (33.40%), HL-60 (29.70%),K562 (28.19%), KG1a (16.23 %) and HEL92.1.7 (8.02%).

The results showed that in evaluation of the method by detecting 50 RHD 1227A positive and 50 RHD 1227A negative individuals, the genotyping method displayed a sensitivity of 100% and a specificity of 100%; in evaluation of the method by detecting 33 DEL positive and 89 DEL negative individuals, the sensitivity was 100%, however, there were two serologically negative samples which were confirmed as positive using genotyping method. After re-testing these two samples with serological method and sequence analysis, it was found that original serological method gave false negative results and genotyping method still showed 100% specificity. The minimal target DNA concentration of this genotyping method is 8.13 ng/μl.

结果表明：在50例RHD 1227A阳性和50例RHD 1227A阴性的Rh阴性样本中基因分型方法的灵敏度和特异性都是100％；在33例DEL阳性样本和89例DEL阴性的样本中，基因分型方法的灵敏度为100％，有2例样本血清学结果为阴性而基因分型结果为阳性，重新用血清学方法和序列分析方法复核这2例样本，发现2例都是血清学漏检，因而基因分型方法的特异性是100％。
