In this paper, some problems and ways of the quality education for college students are discussed on the ideology, knowledge, morals, psychology, physical health and creativity of the teachers.

The shortage of this article is, because of the lack of knowledge and skill, I should perfect the study of the depth and extent in economic new problem and apply and analyse the prctice.

But students' internalization of knowledge is inseparable from teachers' guidance, and teachers' personality power, knowledge power and expressive power demonstrated in their teaching are still very important to the students' internalization of knowledge.

The characteristics of his writing and his way of pursuing reveal the essential quality of a successful military jounalist in the new century, i.e., fine temperament, spirit of innovation, profound knowledge and self-cultivation, and a sound structure of intelligence and ability.

Hence teachers, especially young teachers ought to have solid basis of profession, comprehensive knowledge and healthy mentality, and colleges should supply situation and opportunities for them.

We shall show that the inverse spectral problem can be used to construct sampling type theorems from the knowledge of the sampling points only.

Calculations of those coefficients and many other situations where frames occur, requires knowledge of the inverse frame operator.

A quantitative structure-retention relationships (QSRR) approach, as one of the all-important areas in modern chemical science, gives knowledge that is practical and necessary for drug design, combinatorial, and medicinal chemistries.

The starting material used abroad is expensive and the yield is low (16%-28%); furthermore, to our best knowledge, no characterization of Compound A is available in the open literature.

The so-called "truss rigid frames" are those rigid frames with trusses as their horizontal beams, of which the two ends are rigidly connected to columns. Within the author's knowledge, all the methods available at present for analyzing such rigid frames are based on Certain special assumptions such as (1) that the positions of the points of contra-flexure in all the columns are previously known; (2) that the end rotations of a truss may be reprensented by that of its assumed line of axis as in the case...

The so-called "truss rigid frames" are those rigid frames with trusses as their horizontal beams, of which the two ends are rigidly connected to columns. Within the author's knowledge, all the methods available at present for analyzing such rigid frames are based on Certain special assumptions such as (1) that the positions of the points of contra-flexure in all the columns are previously known; (2) that the end rotations of a truss may be reprensented by that of its assumed line of axis as in the case of an ordinary beam; or (3) that the end verticals of trusses may be given certain prescribed deformations. Of course, the adoption of any of such assumptions leads to only approximate results inconsistent with the actual deformations of such rigid frames under any loading. Heretofore, the author did not know any correct method for analyzing such rigid frames. In this paper, the author presents two principles of the correct analysis of truss rigid frames. The first principle is that of "moment action on column" for computing the angle change constants of columns, and the second principle is that of "effect of span-change in truss" for computing the angle and span change constants of trusses.As, for computing the angle change constants of a truss, the dummy unit moment is a couple applied to its end verticals, so, for computing the angle change constants of a column, the dummy unit moment must also be a couple applied to the section of column rigidly connected to the end of a truss, in order to effect a consistent deformation at the joint of the two. This is the first principle.A truss just like a curved or gabled beam of which the effect of span-change can not be neglected, so truss rigid frames belong to the same category of what may be called "span-change" rigid frames such as rigid frames with curved or gabled beams. Therefore the span-change constants of trusses should be included besides their angle-change constants for analyzing truss rigid frames. This is the second principle.With the constants of columns and trusses are all computed in accordance with respectively the first and second principles mentioned above, truss rigid frames may be analyzed by any method including the effect of span-change as in the case of rigid frames with curved or gabled beams, and the results thus obtained will be exactly the same as by the method of least work or deflections without any special assumptions.In this paper, after the two principles are described and the formulas for computing the constants of columns and trusses are derived, the correctness of the two principles are then proved by the methods of least work, deflections and slope-deflection. A two-span truss rigid frame is analyzed under the following three conditions:Ⅰ. Applying both of the two principles to obtain the correct results.Ⅱ. Applying only the first principle to show the discrepancies of neglecting the effect of span-change in trusses as born out by comparing the results of Ⅱ with Ⅰ.Ⅲ. Applying neither of the two principles, and the truss rigid frames being analyzed by the special assumption (2) mentioned above with the line of axis at the bottom chord of truss, in order to show the discrepancies of neglecting the moment action on column as born out by comparing the results of Ⅲ with Ⅱ. For the sake of brevity, only the results are given in Tables 1 to 5 without computations in details.Although the discrepancies of neglecting the moment acticn on column are only slight as shown by comparing the results of Ⅲ with Ⅱ in Tables 2, 4 and 5, there is no reason why special assumptions should not be replaced by the correct principle of moment action on column to obtain correct results. As shown by comparing the results of Ⅱ with Ⅰ in Tables 2, 4 and 5, the discrepancies by neglecting the span change in trusses are generally considerable and, in certain particular part, as large as 3000%. Therefore, for the safe and economical design of truss rigid frames, the effect of span-change in trusses should not be neglected in their analysis.Finally, for analyzing co

The investigation of the properties of loess constitutes a highly specialized branch of soil engineering. The design and construction of foundations and earthwork in this soil involve many uncertainties that have not been solved. Among all uncertainties the following are considered the most important items:(1) the changes of bearing capacities caused by variations in the strength of the cohesive bond due to changes in its moisture content, and(2) the methods of ascertaining the amount of its settlement under the combined action of foundation loads and of percolating water.In order to prevent foundations against settlement the "Provisional Code for the Design of Natural Foundations" gives a set of rules of precautions for designers to observe, which include the prevention of water from getting into the foundations, artificial strengthening of the soil and the designing of superstructures in such a way that they will adjust themselves to settlement. Before the adoption of any of such precautions could be decided, the accuracy in evaluating the amount of possible settlement of the soil is a problem of prime importance, which unfortunately cannot be satisfactorily obtained.This paper attempts to give some predominent characteristics of loess, the points of contradiction between the assumptions made in the old designing code and the results derived from actual work, a comparison of the salient features of the old code with the new code of ordinance of the U. S. S. R., 1955, and some suggestions regarding further developments of this branch of soil engineering. Several cases of actual construction work in loess in recent years are also cited which, owing to our incomplete knowledge of the soils, nature, have inevitably either caused unnecessary expenses to the works, or brought about results detrimental to the stability of structures.In this branch of soil engineering have, therefore, many difficulties yet to be contended with. It is hoped that this paper could be of some reference value to research engineers in this line and the knowledge of loess be further developed in view of the increasing pressure of necessity in our present construction work.

This paper reports on biological investigations on two Scelionid egg-parasites,Telenomus dendrolimusi Chu and Telenomus sp., of the pine caterpillar (Dendroli-mus punctatus), and their parasitization under field conditions at Nanking, Kiangsuand Changshan, Chekiang during 1954 to 1955. The effect of cold storage on theeggs both of pine caterpillar and the parasites is discussed. Telenomus dendrolimusi is the well-known egg parasite of pine caterpillar inChina. Formerly there was no knowledge that Telenomus sp. parasitizes the cater-pillar egg in China, and this is the first report of its parasitization. Differences bothin the morphological characters and physiological reactions of the adult and larvaof Telenomus dendrolimusi and Telenomus sp. show that they are two different spe-cles. According to data at hand, Telenomus sp. is distributed in Nanking, Kianin,(Kiangsu Province), Changshan(Chekiang Province) and Canton(Kwangtung Pro-vince). It forms about 80% of the two Scelionids found in Nanking. Telenomus sp. overwinters in the larval stage in the egg-shall of its host, Ly-mantria sp. (Lepidoptera, Lymantriidae) and the adult emerges from the time whenthe first-brood Dendrolimus eggs appear the following spring. It does not perish either from low temperature in winter or from shortage of food or hosts in spring.So it is saperior to Telenomus dendrolimusi from the standpoints of biological con-trol practice. In Nanking, Telenomus dendrolimusi has 10-12 generations and Telenomus sp.has 8-9 generatiom annually. The proportion of females is about 80%. A female ofTelenomus sp. parasitizes 30 host-eggs in average, this amount being twice as manyas parasitized by Telenomus dendrolimusi. It oviposites all its eggs within a shortperiod and is easy to rear on a large scale under laboratory conditions. One-dny-old pine caterpillar egg was stored in a refrigerator at 4℃ for onemonth, the development of the embryo was not effected. The mature larvae ofTelenomus sp. are best suited for cold storage. Adults emerging from these eggsafter treatment produce normal healthly progeny without showing any ill effects.
